    We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator as a in the home, still has some use environment. In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large, because a large number of items need to be insulated, so the temperature in the cold storage is strict. In such cases the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is, to form a vapor barrier layer.The height of the warehouse, the horizontal and vertical of the warehouse shall be designed according to the refrigeration, refrigeration equipment, transportation and stacking conditions. The selection of insulation board is very important for Guangdong cold storage. At present, the vast majority of cold storage use polyurethane insulation board. What are the characteristics and advantages of polyurethane insulation board?Bedgosh,The fresh-keeping storehouse is generally composed of maintenance structure and refrigeration equipment. It is mostly cooled by compressor, and the gasification temperature is very low as coolant, so that it can evaporate under low pressure and mechanical conditions, and absorb the heat in the storage warehouse, so as to achieveIt is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day, and the door of the cold storage must be locked.Innsbruck,The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade, and pay attention to the waterproof of the lamp.Cold storage board, compressor, and other components in the cold storage can reasonably adjust the evaporation and condensation temperature, so as to improve the reduction of power consumption and reduce the production cost. Professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, quality assurance, professional, timely supply and high cost performance. It has become the preferred brand for many wire products. Welcome to buy! Save more resources.The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, in the quick freezing warehouse, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.

    After being stored in the medical cold storage project, ventilating medical products may also emit some odors. Once these odors are stored in a certain quantity, they will also have a certain impact on other products. Therefore, we must carry out regular ventilation in the process of daily use, so as to effectively reduce the storage time of products. If the medical cold storage project uses row tube refrigeration, it will also affect the effect of. Therefore, I hope you must pay attention to defrosting.When installing and splicing the storeboard in the fresh-keeping storehouse, it needs to be tightly sewn to ensure the tightness; The fresh-keeping storehouse will discharge water during operation, and the drainage pipe should be installed in a place that can circulate; An anti-collision barrier shall be installed around the door of the fresh-keeping storehouse to prevent the door from being damaged by impact. To play an eye-catching role, the fresh-keeping storehouse shall be equipped with emergency lights, alarm devices and safety channels to facilitate self rescue or alarm for help in case of emergencies.If there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.Administration,Suggestions on the quantity of polyurethane cold storage insulation materials: cold storage investment is a long-term and profitable investment. A high quantity of hair can certainly reduce the initial investment, but it is necessary to grasp a certain limit and comprehensively consider the long-term energy consumption and initial investment, because the insulation effect of polyurethane cold storage insulation materials has a parabolic linear correlation with its bulk weight; A large number of studies have shown that the foam bulk density has better thermal insulation performance at ~ kg / cubic meter. Therefore it is usually recommended that the number of thermostat refrigeratory outlets should be ~ square / ton.The combined cold storage does not cool or the cooling effect is poor. Check whether the condenser of the refrigerator is dirty. Whether frost is too thick on the evaporator in the warehouse. Check whether the refrigerant is leaking (apply soapy water to the pipeline connection, and if bubbles are generated, it indicates that the refrigerant is leaking). And ask the combined cold storage engineering personnel to supplement the refrigerant and deal with the leakage. Check whether the sealing of the combined cold storage door is intact and eliminate it. Whether the refrigerator of the combined cold storage works. Whether the parameter setting of the computer controller of the cold storage is correct, and reassemble the cold storage door for installation. Check whether the cooler in the cold storage fails and replace it. Whether there is enough clearance for stacking articles in the warehouse and dredge them.The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam,BedgoshDesign of medical cold storage, the deterioration of foam performance is also a very important index. When the white material is prepared, the surface of some polyester materials can make the foam have better toughness and impact resistance, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure, which is slightly brittle at the initial stage, but generally disappears after a few days and then maintains the stable performance of cold storage insulation materials for a long time.

(note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).Bedgosh,Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin,BedgoshInstallation of cold storage, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene,BedgoshHow much is the installation of cold storage per square meter, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, so we try to use screw parallel units. The great advantage of this unit is that it can turn on all equipment, just like the shift at work, so that the compressor can work and rest in turn.Emergency measures during the use of the medical cold storage project, it may also encounter power failure or power failure. In fact, most medical cold storage projects will be equipped with emergency equipment so that the medical cold storage project can achieve the effect of normal power supply. Once the automatic temperature or humidity monitoring system is abnormal, the cold storage door should be closed in time, So as not to expose more air conditioners, resulting in corresponding problems in the quality of stored products. The medical cold storage project also has a self rescue system in time. If the temperature of the cold storage exceeds the limit, the system cooling system will also be turned on. When the temperature returns to normal, it will be automatically turned off.

    The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade and pay attention to the waterproof of the lamp.Step of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time, which not only has excellent fire resistance, but also has high cost performance. There are several types of cold storage insulation materials. One is the plate produced and processed into a fixed shape and specification with fixed length, total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts cm thick cold storage plate, cm or cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam, and the raw materials can be sprayed into the brick or concrete warehouse of the cold storage to be built immediately. After shaping, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance, but the cost is low.Lamezia Terme ,In addition, water shortage or insufficient water in water-cooled machines will increase the exhaust temperature of the fresh-keeping warehouse. The condensation pressure is abnormal and the exhaust pressure of the fresh-keeping warehouse decreases.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature.

    Cold storage design step: the selection of cold storage refrigeration system the selection of cold storage refrigeration system is mainly the use of cold storage refrigeration compressor and air conditioning evaporator. Generally, small and medium-sized refrigerators are dominated by fully enclosed refrigeration compressors. Due to the small output power of the fully enclosed refrigeration compressor, the price is relatively cost-effective; Small and medium-sized refrigerators are generally dominated by semi closed refrigeration compressors; Semi closed refrigeration compressor is adopted for large and medium-sized refrigerated warehouses. When adopting, ammonia refrigeration unit can also be considered. Because the output power of ammonia refrigeration unit is large and can be used for machine use, but the installation and management of refrigerated warehouses are cumbersome. When using the air-conditioning evaporator, the high-temperature cold storage uses the industrial cold fan as the air-conditioning evaporator. Its characteristic is that the temperature reduction speed is faster, but it is easy to lead to the water consumption of the cold collection; Medium and ultra-low temperature refrigerators are dominated by seamless evaporation pipe slots, which is characterized by very good temperature control effect and moderate cold storage.Let's see,Lamezia Terme Where is the refrigerator installed,Another reason is that there are many refrigerants in the system. In this case, find the leakage point first, focus on the connection of each pipeline and valve, repair the found part, and then fill in sufficient refrigerant.The exhaust pipe and return pipe shall have a constant slope. When the condenser is higher than the compressor, the exhaust pipe shall slope towards the condenser and a liquid ring shall be installed at the exhaust port of the compressor. Prevent the gas from cooling and liquefying back to the high-pressure exhaust port after shutdown, and cause liquid compression during restart.When installing polyurethane insulation board,Lamezia Terme Installation and design of cold storage, ensure that its surface is smooth and flat without scratch and warpage.Lamezia Terme ,For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin,Lamezia Terme Which company is good for cold storage installation, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane board has very good thermal insulation performance and does not absorb moisture.The installation of top warehouse plate should be carried out alternately with the installation of wall plate, and the wall plate should leave a gap for withdrawing construction equipment; During the installation of the top warehouse plate, the end steel sheet at the overlap with the wall plate shall be disconnected for mm to prevent the cold bridge from running cold; Two layers of foaming materials shall be evenly and continuously punched on the joint surface between each top warehouse plate. Rivets shall be pulled and fixed at the internal and external lap joints of the steel plate, and the rivet spacing shall be mm; According to the design drawings, if there are supporting beams, columns and supporting steel frames in the warehouse, the setting out and positioning shall be carried out and accurate and clear marks shall be made according to the requirements of the design drawings; Weld or install the support beam, support steel frame etc., and the welded junction shall be moisture-proof and treated according to the drawing requirements.

    When installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.Standard requirementsThe height of the warehouse, the horizontal and vertical of the warehouse shall be designed according to the refrigeration, refrigeration equipment, transportation and stacking conditions. The selection of insulation board is very important for Guangdong cold storage. At present, the vast majority of cold storage use polyurethane insulation board. What are the characteristics and advantages of polyurethane insulation board?There are several types of insulation materials. One is to produce and process plates with fixed shape and specification, fixed length, total width and thickness. Plates of corresponding specifications and models can be selected according to the installation of the refrigerator body. High and medium temperature refrigerators generally use cm thick refrigerator plates, and ultra-low temperature refrigerators and freeze-cleaning refrigerators generally use cm or cm thick refrigerator plates; Another kind of sprayed polyurethane foam can be sprayed immediately into the finished brick or concrete warehouse. After forming, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, etc. polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption and poor fire resistance, but the cost is low. The structure of modern cold storage is developing in the direction of dress matching architecture. They are made into prefabricated components including steam barriers and heat shields to ensure field assembly. Its advantage is that the project construction is convenient, fast and movable, but the project cost is relatively high.When the cold storage is used for the first time or shut down for a long time,BalmFresh storage installation, it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse, it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.Balm,For water-cooled units, the turbidity of cooling water shall be frequently, the cooling water shall be replaced frequently, and whether the running, emitting, dripping, leakage and other conditions of the water supply system exist.Improper adjustment or blockage of throttle valve, too large or too small refrigerant flow: improper adjustment or blockage of throttle valve will directly affect the refrigerant flow into evaporator. When the throttle valve is opened too large, the refrigerant flow is too large, the evaporation pressure and evaporation temperature also increase, and the decline rate of warehouse temperature will slow down; At the same time, when the throttle valve is opened too small or blocked, the refrigerant flow will also decrease, the refrigeration capacity of the system will also decrease, and the decline rate of warehouse temperature will also slow down.The assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material, which has excellent thermal insulation performance, storage and circulation effect and reduces operation energy consumption. Of course, more important is the choice of refrigeration system. For example, the refrigeration system of fluorine refrigerant is still the mainstream, but when selecting the type and power of cooling equipment it is necessary to calculate the data for the installation of cold storage, and then make a high-quality choice.

    Cold storage, compressor overload, lack of refrigerant low pressure too low, excessive air intake, compressor jamming.Workshop cost,For the ground insulation of large cold storage we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.The location temperature,KasetaPharmaceutical cold storage installation company, temperature difference and other main parameters of fresh-keeping warehouse equipment wholesale shall be set according to the specific situation of the frozen warehouse, and the main parameters cannot be changed at will.

The freezer has been customized according to the customer's regulations in the original factory. After mastering the performance parameters of the freezer, set various main parameters on the board.Cold storage has strong stability. Polyurethane foam technology makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is,KasetaCold storage installation company, under the unfavorable local temperature and humidity conditions, the characteristics of the cold storage still do not separate and fall off from the carrier layer and remain stable under normal conditions.Kaseta,When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure, especially the heat insulation structure, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), the size changes often reflect bubble cracking or falling off, and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present, polyether commonly used in spraying materials contains a large number of functional components and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage, and the reaction is complete, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, achieve the effect of stable size, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.

    only with sufficient cold storage installation skills can we ensure that the cold storage is more energy-saving and power-saving after installation, and is not prone to failure, convenient use and management and long service life.The refrigerant charge is insufficient. At this time, just add enough refrigerant.peas,After the installation of the controlled atmosphere storage, the temperature is too low, perhaps because the unit is too large, it can be found that the temperature of the goods is still at a high level, or perhaps because the thermal insulation effect of the controlled atmosphere storage is relatively poor after the installation of the controlled atmosphere storage, then the heat dissipation will be accelerated, This phenomenon may be caused by the poor quality of the selected modified atmosphere storage board. It is suggested that when selecting the modified atmosphere storage board, we must pay attention to its thickness. Only the modified atmosphere storage board with the required thickness can have a certain thermal insulation effect.The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.Ingolstadt,peasDesign and installation of fruit cold storage,The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, resulting in poor thermal insulation and thermal insulation effect, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.Wall and floor fixtures shall start at corners. According to the plate layout drawing, drill a hole at the corresponding elevation in the middle of the plate width. When drilling the electric drill should be perpendicular to the plate surface. Put the mushroom head nylon bolt in the hole, tighten the angle iron, and tighten it horizontally,peasInstallation and maintenance of maintenance cold storage, so as to make the nylon bolt on the surface of the warehouse plate slightly concave. When setting up the wall panels, foam data and other soft data should be laid on the floor slots along with the floor of the storehouse, so as to avoid damaging the storehouse. After the two corner panels are neutrally removed from the floor the plane position of the wallboard and the verticality of the storehouse should be adjusted in time according to the location of the laying line, and check whether the top elevation of the wallboard can be correct. After the position of the wallboard is correct, weld the angle iron on the plate beam and fix the inner and outer corners. When welding the angle iron parts, compressor overload, lack of refrigerant, low pressure too low, excessive air intake, compressor jamming.

    The wide, light and thin walls are made of rigid polyurethane foam at the same time as structural materials, making the whole structure have the advantages of light weight, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit, which allows the use of thinner plates during construction and saves building space.If the controlled atmosphere storage is not used for a long time, does it also require refrigeration? If the controlled atmosphere storage is not used for a long time after installation, it does not need refrigeration operation as long as it does not show fluorine leakage. However,peasWhich is a good installation for small cold storage, there may be fluorine leakage due to long-term non use, so refrigeration operation should be carried out at this time.The two sets of connectors between the cold storage shall be wedged tightly, and the two sets of connectors shall be fixed at the upper, outer and lower sides of the cracks in the cold storage respectively. The lower connector shall be as close as possible, so as to facilitate the use of concrete to cover the connector in the future.Honesty is the foundation,The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage, it should be determined according to the type, quantity, frequency, cycle, whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, the storage capacity of -kg per cubic meter can be referred to, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..The insulation board of the cold storage adopts polyurethane double-sided color steel plate. The main effect of this cold storage insulation board is good sealing performance, insulation effect and moisture-proof effect, so as to ensure the refrigeration effect of the cold storage. The electric cold storage door is adopted for the cold storage door, and the cold storage management personnel can timely and effectively open and close the door when entering and leaving, so as to avoid the loss of refrigeration capacity of the cold storage.Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate, compressor line is disconnected, fuse is blown, thermal relay acts, high voltage switch acts, compressor is locked line is falsely connected or loose fault phenomenon: it stops in a short time after drying, ambient temperature is too high, condenser is blocked

    How to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, the condensation temperature will rise by ℃ compared with the original temperature, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa, the power consumption will increase by about . It can be seen that it is coldGra,Advantages: no reciprocating motion,GraCold storage and freezing of drugs, so it has the advantages of simple structure, small volume, light weight, few parts (especially few vulnerable parts) and high reliability; Torque change is small. I am engaged in all kinds of cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage and other materials all year round.

High balance, low vibration, stable operation and low vibration of the whole machine; It has high efficiency and variable frequency speed regulation technology in the range of refrigeration capacity; The scroll refrigeration unit has no clearance volume, can maintain high volumetric efficiency, low operation noise, good stability and high safety, and is relatively not easy to liquid hammer.Step of cold storage design: define the volume of the cold storage warehouse. The size of the cold storage should be based on the design of a large number of agricultural products to be stored for a long time. This volume is calculated based on the essential volume of stored goods accumulated in the cold storage plus the row to row corridors, the indoor space between the pile and the wall, the ceiling and the gap of the packaging house. After the volume of the cold storage is determined, the length and height width ratio of the cold storage shall be determined. Necessary auxiliary engineering buildings and equipment shall also be considered in the design of cold storage such as working intermediate, special tool warehouse, loading and unloading platform, etc.Ndibene Dahra,Improper adjustment or blockage of throttle valve, too large or too small refrigerant flow: improper adjustment or blockage of throttle valve will directly affect the refrigerant flow into evaporator. When the throttle valve is opened too large, the refrigerant flow is too large, the evaporation pressure and evaporation temperature also increase, and the decline rate of warehouse temperature will slow down; At the same time, when the throttle valve is opened too small or blocked, the refrigerant flow will also decrease, the refrigeration capacity of the system will also decrease and the decline rate of warehouse temperature will also slow down.Installation of box and operating device: the design of box shall be reasonable, and the appearance quality shall meet the requirements of beauty and practicality.

In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large, because a large number of items need to be insulated, so the temperature in the cold storage is strict. In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, and the penetration of the envelope is carried out from outside to inside all year round. R gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer it is effective to seal the hot side of the insulation layer, that is, and pay attention to the waterproof of the lamp.The cooler on the refrigeration unit is very easy to be dirty, so it should be cleaned on time according to the specific situation. To maintain stable heat conduction and practical effect. Good heat removal and cooling. There is no need to accumulate dirt around the refrigeration unit.Cold storage has good water tightness. Polyurethane rigid foam has low water absorption,GraDesign of small cold storage, good permeability to water vapor, foam holes, disconnected and closed porosity of more than %. It is a dense microporous foam material, which is more dense than air surface, and is not easy to permeate. It belongs to hydrophobic materials.retailer,There should be excellent drainage pipe standard around the warehouse, the soil temperature should be low, there should be interlayer under the cold storage, and maintain good natural ventilation. Maintaining dryness is very important for the cold storage. In addition, the phase electricity of the relative volume shall be built according to the output power of the refrigeration unit. If the cold storage is water-cooled and radiating, the deterioration of foam performance is also a very important index. When the white material is prepared, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure, which is slightly brittle at the initial stage, but generally disappears after a few days, and then maintains the stable performance of cold storage insulation materials for a long time.During production in the production workshop, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project,It is required to set up a special tally room (area), and the temperature of the tally area is usually controlled at ~ + ℃.The fresh-keeping storehouse is a device that combines a refrigerator with facilities that use cooling capacity.

    Relative humidity maintenance of quick-frozen warehouse: humidification of quick-frozen warehouse is very important, from centrifugal humidification to high-pressure micro fog humidification, gas-water mixed humidification, to the current ultrasonic humidifier. The utility model has the advantages of small particles, uniform humidification, no freezing and blocking, and no dirty blocking. The air conditioning humidifier we produce is specially designed for all kinds of vegetable and fruit quick freezing warehouses, which is essentially different from other humidifiers in the market: fully closed circulation, that is, take the gas in the warehouse, return to the warehouse through the humidifier and isolate it from the outside air.We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, as a in the home, still has some use environment. In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance.

Over time, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is, to form a vapor barrier layer.malpensa airport ,All equipment connections shall be laid with wire pipes and fixed with clips. PVC wire pipes shall be bonded with glue,malpensa airport How much is the cold storage, and the pipe orifice shall be sealed and wrapped with adhesive tape.When installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.Paijan,However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.Because polyurethane sheet has excellent thermal insulation performance, it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.Preparation, prepare the project planning of cold storage, and prepare the construction site and construction materials. All kinds of materials for cold storage construction are customized according to the needs of customers. Sort out the construction site that meets the requirements, transport all installation materials to the construction site, check the material quality and model, which can be determined according to its own budget and actual needs. At present, most cold storages adopt single-layer steel structure, and are equipped with combined thermal insulation warehouse body, unloading platform refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.Cold storage has good fire and flame resistance. After adding flame retardant polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.How much is it,In the process of realizing your dream, you must remove all the influences. It is very important to recognize that when these beautiful refrigerators are built in the villa room, the collection pit (pool) for flushing (thawing) and drainage should adopt the Countermeasures of avoiding freezing and cleaning and avoiding backflow of water.The products stored in the medical cold storage project must be managed by color code, so as to avoid the problem of purchase errors. In the process of handling, it is also necessary to strictly follow the instructions.Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety, science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.

    Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room, sorting room, quick freezing room, refrigeration room, channel, unloading platform, etc.property right,Install the library body. Generally, the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat, compact and solid, without hollow feeling, load-bearing, antifreeze, moisture-proof, etc.The selection of the refrigeration system of the controlled atmosphere storage is mainly the selection of compressor and evaporator. The refrigeration system is the core of the controlled atmosphere storage, which is mainly composed of compression system,malpensa airport Which is a good installation for small cold storage,malpensa airport Pharmaceutical cold storage certification, condensation system, evaporation system and regulating valve. In addition, there are auxiliary parts such as fan, duct and instrument. The whole refrigeration system is a sealed circulating circuit in which the refrigerant circulates, The compressor is the heart of the refrigeration system, which promotes the circulation of refrigerant in the system. The function of the condenser is to remove the heat from the compressed gaseous refrigerant and condense it into liquid refrigerant; The cooling methods of the condenser include air cooling, water cooling and the combination of air and water. Air cooling is only used in the refrigeration equipment of small-scale air-conditioned storage. The role of the evaporator is to provide cooling capacity to the air-conditioned storage. The evaporator is installed in the air-conditioned storage. The blower blows the cooled air to all parts of the storage. The air duct of large-scale air-conditioned storage is commonly connected with the evaporator to extend the air supply distance, Make the storage temperature drop and even.The foundation of cold storage is affected by low temperature and the water in the soil is easy to be frozen. Due to the volume of frozen soil, the ground will be broken and the whole building structure will be deformed. If the damage is serious, in addition to the thermal insulation layer, the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading, unloading and transportation machinery and equipment. Therefore, the structure of the cold storage plate shall be firm and have large bearing capacity. In low temperature environment, especially in the process of periodic freezing and thawing cycle,When hot ammonia defrosting or electric defrosting is selected as the cooling fan, professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage safety, environmental protection and economy! The products are exported to foreign countries and are deeply trusted. Defrosting and drainage can be discharged immediately. Electric heat tracing and insulation can be selected for the defrosting and drainage pipeline of the warehouse location.For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.The equipment configuration is reasonable and the service life of the quick freezing warehouse is long. The reasonable equipment configuration of the quick freezing warehouse can greatly prolong the service time of the quick freezing warehouse. Some compressors are easy to be damaged when they work at full load for a long time, so we try to use screw parallel units. The great advantage of this unit is that it can turn on all equipment, just like the shift at work so that the compressor can work and rest in turn.

    Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.The water-cooled cold storage shall keep the cooling water tower clean and keep the air around the water tower circulating with low temperature, so as to avoid sundries from entering the cooling tower and reduce the heat dissipation efficiency.The use of large-scale cold storage is naturally very strict in installation and material selection. Therefore, in the face of the above possible situations, we can strictly screen the insulation board materials of cold storage, which can effectively alleviate or solve the above problems. However, at present, there are many fields using cold storage insulation board, so the details of the use environment should be considered for the wood making of many such products in the market.Installation material list,Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.During the installation of long-span top warehouse plate, if the supporting steel beam has been installed in the warehouse, the installation and construction of the lifting layout shall be realized before the installation and construction of the top silo plate and each top warehouse plate shall be riveted in two rows; If the lifting point type is adopted, so as to ensure that each lifting point can be installed at the same time during the installation of the top silo plate; The lifting point shall ensure that there are at least two points along the width direction of each warehouse plate.

Sort out the construction site that meets the requirements, transport all installation materials to the construction site, check the material quality and model, and start the installation of cold storage after confirmation.The suction pressure of fresh-keeping storehouse remains unchanged, and when the exhaust pressure increases, the exhaust temperature also increases. Both cases are caused by the increase of compression ratio of fresh-keeping warehouse. Too high condensation temperature and exhaust temperature of fresh-keeping warehouse are unfavorable to the operation of compressor when the suction pressure decreases, which should be prevented. Too high exhaust temperature will dilute the oil and even carbonize and coke, which will worsen the compressor conditions of the fresh-keeping warehouse.Cold storage construction: which one is suitable for you?

In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, and the penetration of the envelope is carried out from outside to inside all year round. R gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is, to form a vapor barrier layer.

    Generally, in the actual operation of the refrigeration system, because the temperature conditions are constantly changing, only by relying on the careful operation of the cold storage management personnel and accurately adjusting the operation of the refrigeration equipment of the cold storage, can the refrigeration system always be in the ideal working state and achieve the effect of energy saving.Core tip: in the cold storage project, only with sufficient cold storage installation skills can we ensure that the cold storage is more energy-saving and power-saving after installation, and is not prone to failure, convenient use and management and long service life.Jessheim,There are several types of insulation materials. One is to produce and process plates with fixed shape and specification, fixed length, total width and thickness. Plates of corresponding specifications and models can be selected according to the installation of the refrigerator body. High and medium temperature refrigerators generally use cm thick refrigerator plates and ultra-low temperature refrigerators and freeze-cleaning refrigerators generally use cm or cm thick refrigerator plates; Another kind of sprayed polyurethane foam can be sprayed immediately into the finished brick or concrete warehouse. After forming, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, etc. polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption and poor fire resistance, but the cost is low. The structure of modern cold storage is developing in the direction of dress matching architecture. They are made into prefabricated components including steam barriers and heat shields to ensure field assembly. Its advantage is that the project construction is convenient, fast and movable, the deterioration of foam performance is also a very important index. When the white material is prepared, the surface of some polyester materials can make the foam have better toughness and impact resistance, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure,JessheimWhich cold storage installation company is good, which is slightly brittle at the initial stage, but generally disappears after a few days, and then maintains the stable performance of cold storage insulation materials for a long time.Ban Pong,Cold storage construction: which one is suitable for you?

When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.Polyurethane spraying is widely used in large and medium-sized refrigerators. Different well-known brands are produced at different prices, and the product quality is relatively large. However, it is not high-quality or good goods. This is the result of long-term cooperation.

Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then, the water vapor in the cold storage is easy to condense, and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water, its nature will be greatly reduced. Therefore, it is necessary to be careful to select extensional perlite as cold storage.Precautions for transforming the warehouse into a fruit preservation warehouse: determine the area and height of the cold storage according to the estimated number of fruits. In this way, after all, the warehouse is too large and the stored fruits are too few, resulting in a large waste of electric energy.Insufficient refrigeration dose and capacity in the system: there are two main reasons for insufficient refrigerant circulation,property right,Other aspects: in the design process of food cold storage, it is also necessary to consider the cooperation between the cold storage and on-site fire fighting, ventilation, water and electricity systems. It should meet the requirements of safety, science and environmental protection. When designing and installing the cold storage, the drainage problem must be considered, and the following points should be paid attention to during redesign and installation.Different food processing technical processes for the construction of cold storage are combined with local urban planning. The construction of cold storage is the design requirements and construction of cold storage, which not only avoids the cross pollution between foods, a reasonable overall layout, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.

    The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage, it should be determined according to the type, quantity,JessheimCold storage engineering installation, frequency, whether to use shelf stacking and so on.

    Cold storage design step: the selection of cold storage refrigeration system the selection of cold storage refrigeration system is mainly the use of cold storage refrigeration compressor and air conditioning evaporator. Generally,violetPharmaceutical company cold storage, small and medium-sized refrigerators are dominated by fully enclosed refrigeration compressors. Due to the small output power of the fully enclosed refrigeration compressor, the price is relatively cost-effective; Small and medium-sized refrigerators are generally dominated by semi closed refrigeration compressors; Semi closed refrigeration compressor is adopted for large and medium-sized refrigerated warehouses. When adopting, ammonia refrigeration unit can also be considered. Because the output power of ammonia refrigeration unit is large and can be used for machine use, but the installation and management of refrigerated warehouses are cumbersome. When using the air-conditioning evaporator, the high-temperature cold storage uses the industrial cold fan as the air-conditioning evaporator. Its characteristic is that the temperature reduction speed is faster, but it is easy to lead to the water consumption of the cold collection; Medium and ultra-low temperature refrigerators are dominated by seamless evaporation pipe slots, which is characterized by very good temperature control effect and moderate cold storage.Cold storage has good fire and flame resistance. After adding flame retardant, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, unlike flow burning and flashover like extruded board, it can be closed as a whole after fire prevention treatment to form non combustible products.violet,When the ceiling fan is too heavy, or angle iron shall be used as lintel. Lintels shall span over another roof and wall panel to reduce load.With the rapid development of modern commerce, the original cold storage for the purpose of product storage can no longer meet the rapid, accurate and small batch circulation needs of modern commodities. Therefore,When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure, especially the heat insulation structure, being damaged by moisture and freezing. Therefore, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. Professional projects include: cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other related businesses. Merchants who hope to have this business please consider the wide scale of warehouse temperature control, the selection and placement of cooling equipment and the description of wind speed field, which are suitable for the cold storage needs of a variety of goods. Equipped with perfect storage temperature active detection, recording and active control equipment.Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is very important to select materials with good thermal insulation. Cold storage is a better material selection, and in the production process of cold storage, there will be no condensation in the cold storage of the plant. Condensation inside the cold storage or inside the insulation layer is harmful. Irreversible damage or deformation occurs in the new external insulation, and the external surface temperature of the external wall changes sharply. For example the insulation and sound insulation effects of polyurethane insulation board are relatively good, which can be used in many industries. As we all know, the cold storage has great requirements for the thermal insulation effect of building materials. If the thermal insulation effect of building materials is not good, the cold storage will consume more energy during operation, and can not guarantee a good refrigeration effect. The performance of polyurethane insulation board meets the construction requirements of cold storage, so a large number of polyurethane insulation boards need to be used in the construction of general cold storage. Next let's understand the physical properties of polyurethane insulation board.

Of course, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.However, due to high labor intensity and incomplete defrosting, it has limitations.Large space rate of quick-frozen warehouse: for quick-frozen warehouses of the same size, reasonable design schemes store more goods than unreasonable ones. For the fixed size quick freezing warehouse, we reasonably designed to expand the original storage capacity of boxes to boxes,Artificial refrigeration keeps the room at a constant temperature. The walls, floors and flat roofs of large cold storages are laid with thermal insulation materials with a certain thickness to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color.Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil,violetPrice of cold storage, in order to maintain the set temperature requirements, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, the condensation temperature will rise by ℃ compared with the original temperature, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa, the power consumption will increase by about . It can be seen that it is coldWhen installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.

    According to the size and nature of the cold storage area and in combination with local regulations, the construction form of food cold storage warehouse is to determine the plane layout based on the site, whether it is a single-layer or double-layer warehouse, and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity, production process, refrigeration, product stacking, temperature, etc. are used to determine the size and location of the cold storage room, so that it can become a whole.original, so reasonable maintenance is particularly important.The exhaust temperature of the compressor in the fresh-keeping warehouse can be read out from the thermometer on the exhaust pipeline. It is related to the adiabatic index long-term continuous operation will inevitably lead to equipment aging compression ratio and suction temperature of refrigerant. The higher the suction temperature, the greater the compression ratio, the higher the exhaust temperature, and vice versa.However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.violetFor the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank.The construction of cold storage in site selection bears the circulation of low-temperature goods. Therefore, the transportation convenience of cold storage construction site should be given priority in site selection, such as proximity to roads, railways, etc. At the same time, the location of the cold storage should avoid large pollution sources and direct sunlight, and the construction of the cold storage should have good drainage and ventilation conditions.

    What should be considered in building a cold storage? In these aspects, food cold storage is a systematic project of artificial refrigeration to ensure food quality and reduce food decay in a low-temperature environment. Refrigeration technology affects the design of food cold storage, meets the needs of refrigeration technology, convenient production, energy saving and cost reduction. What problems should be considered in the construction of food cold storage?The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel, which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.Henforth,Therefore, the cold storage also needs regular maintenance every year, so as to ensure its stable operation.The cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of polyurethane cold storage board is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is to prevent the temperature transmission of cold storage board due to large internal and external temperature difference, so as to make the cold storage more energy-saving and improve the working efficiency of cold storage.El Ejido ,For cold storage, it is very common in our production and life. Cold storage is very important for food freezing and preservation, but its energy consumption is very large in the use of cold storage. How can we solve this problem?During installation, the plates shall be handled with care. Rough operation is strictly prohibited. Burrs shall be removed at the cutting opening to prevent scratching the plate surface and workers.The butt joint between the top warehouse plate and the end of the top warehouse plate shall be treated to prevent air leakage and cold running. After all the top warehouse plates are installed the butt joint shall be filled with foaming material, and the mm wide color steel plate shall be sealed at the butt joint with pull riveting.

    At ordinary times, users should check the sealing degree of the gap of the cold storage, and notify the cold storage for maintenance in time if damaged parts are found.After startup, first listen to whether the sound of the compressor is normal, and see whether the condenser and cooling fan operate normally.During the early operation of the refrigeration unit, carefully observe the oil return of the compressor and keep it clean. If it is found that the oil level is not clean enough or the oil level drops, so as to avoid bad compressor and reduce the service life of the compressor.property right,With the rapid development of modern commerce, the original cold storage for the purpose of product storage can no longer meet the rapid, accurate and small batch circulation needs of modern commodities. Therefore the logistics center cold storage cold chain for the purpose of product distribution came into being and developed rapidly, playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking,HenforthCold storage transfer, every ℃ increase in the evaporation temperature of the cold storage can save energy by ~ . Therefore, on the premise of meeting the refrigeration process of the product, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.All wiring shall be neat. All switches and keys shall be opened and closed sensitively, reliably and accurately. Special connectors shall be used for wiring, and power protection shall be provided for the box and each power branch.

    Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.technological innovation,There are many kinds of cold storage. According to the material, stainless steel plate and salted steel. Among them color steel plate has strong anti rust ability,HenforthFresh storage installation Telephone, but stainless steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout, it is divided into flat plate and wave plate. The former is flat after the surface material is formed, and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials, the thickness of stainless steel is .mm and mm, without color requirements; The thickness of salted steel plate is .mm, without color requirements; The thickness of PE paint baking board is .mm, .mm ivory white, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the mm storage plate is mm, and the thickness of the vertical plate is mm and mm, which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm, which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm, which is suitable for the thermal insulation conditions above ℃. In fact, there are many other classification methods of cold storage. Determined by the current processing technology, it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate, vertical angle plate W = mm, W = mm, W = mm and W = . The dimensions of non-standard plates are different from those of Wa,HenforthWhich is cheaper to install in cold storage, WB and W.The suction pipeline of the compressor and the return pipeline of the cooling fan shall not be smaller than the size indicated in the sample to reduce the internal resistance of the evaporation pipeline.The overall construction achievements of the cold storage project have been put into use, and the service life can reach years.HenforthOther aspects: in the design process of food cold storage, it is also necessary to consider the cooperation between the cold storage and on-site fire fighting, ventilation, water and electricity systems. It should meet the requirements of safety, science and environmental protection. When designing and installing the cold storage, the drainage problem must be considered, and the following points should be paid attention to during redesign and installation.Emergency measures during the use of the medical cold storage project, it may also encounter power failure or power failure. In fact, most medical cold storage projects will be equipped with emergency equipment, so that the medical cold storage project can achieve the effect of normal power supply. Once the automatic temperature or humidity monitoring system is abnormal, So as not to expose more air conditioners, resulting in corresponding problems in the quality of stored products. The medical cold storage project also has a self rescue system in time. If the temperature of the cold storage exceeds the limit, the system cooling system will also be turned on. When the temperature returns to normal, it will be automatically turned off.Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, the condensation temperature will rise by ℃ compared with the original temperature, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa, the power consumption will increase by about . It can be seen that it is cold
