Panel types of quick freezing warehouse: color plastic steel plate, salted steel plate, stainless steel plate, embossed aluminum, etc.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 .-..Wieden ,The suction pressure of fresh-keeping storehouse remains unchanged, and when the exhaust pressure increases, the exhaust temperature increases; If the exhaust pressure remains unchanged, when the suction pressure decreases, 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, 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.During the installation of long-span top warehouse plate, if the supporting steel beam has been installed in the warehouse, the top warehouse plate and the supporting steel beam shall be fixed with pull rivets during the installation of each warehouse 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.Uchqurghon the installation and construction of the lifting layout shall be realized before the installation and construction of the top silo plate,What should be considered in building a cold storage?

During installation, then turn off the main power supply and oil heater turn off the unit first, and drain the water in the system.The cold storage shall be regularly overhauled and maintained, so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.Quality recommendation,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.Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment, use the volatilization of the refrigerant to immediately cool the air in the air, and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed, small heat conduction temperature difference and simple system software, so it is widely used.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.

Electric heat tracing and insulation can be selected for the defrosting and drainage pipeline of the warehouse location.Compression refrigerator is commonly used, which is mainly composed of compressor, condenser, throttle valve and evaporation pipe. According to the way of evaporation pipe device, it can be divided into direct cooling and indirect cooling. Direct cooling the evaporation pipe is installed in the refrigerated warehouse. When the liquid coolant passes through the evaporation pipe, it will directly absorb the heat in the warehouse and cool down.

When the cold storage is built at the water level it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.Now let's analyze the production and use requirements of the cold storage. There is no condensation in the cold storage. Condensation in the cold storage or in the insulation layer is harmful. During the drying process of the new wall or under winter conditions, when the water vapor with high indoor temperature migrates outdoors, it is impossible to condense in the wall due to the obstruction of the cold storage.Jerino,If the relative flow changes little, there is little difference in power consumption among several regulation modes, that is the regulation mode has little impact on the energy-saving effect, or even does not save energy, but consumes more power due to the existence of the regulation device, and the variable speed regulation curve is close to the ideal curve. Therefore, the variable speed regulation mode is superior, especially the energy-saving scheme of variable frequency motor speed regulation is recommended, but the frequency conversion device needs to be added. It is recommended to actively try out the variable frequency speed regulation of small and medium capacity. Due to the high capacity and high voltage variable frequency speed regulation device, it should be combined with the specific situation and comprehensive comparison. Generally speaking, the greater the regulation depth, the more significant the energy-saving effect.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.

Fault phenomena: unit current is large and voltage is too low; Loose wiring; The unit pressure exceeds the rated pressure; The oil separation core is blocked; Device failure; Host failure; Main motor fault; Fault phenomenon: the unit cannot be started and the fuse is broken; The temperature switch is broken; Loose wiring; Thermal relay of main motor acts; The thermal relay of cold storage fan motor acts; The transformer is broken; No power input (unit); Failure not eliminated (unit); The actuator is faulty.

Various construction materials, such as material certificate, test report and stage acceptance record, shall be carried out simultaneously with the project construction, carefully, timely, accurately and comprehensively reflect the whole process of production and construction, and actively cooperate with the owner in design change and technical negotiation.Cold storage construction: which one is suitable for you? Which one is suitable for you?Lipkovo,The exhaust temperature of fresh-keeping storehouse is directly proportional to the compression ratio and suction temperature. If the suction superheat temperature of the fresh-keeping warehouse is high and the compression ratio is large, the exhaust temperature is also high. If the suction pressure and temperature remain unchanged, when the exhaust pressure increases, the exhaust temperature also increases.Panel types of quick freezing warehouse: color plastic steel plate, salted steel plate, stainless steel plate, embossed aluminum, etc.Abeche,During the cold storage commissioning, special personnel shall be assigned to ensure that the surface of the cold storage plate shall reflect evenly without condensation and cold running; Sealing conditions of joints and holes; Whether the warehouse door and delivery port are not tightly sealed, and timely deal with the problems of insulation and seal failure such as degumming and air leakage.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 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,LipkovoMedical 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, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..

In fact, there are some unique installation skills when installing the cold storage? The cold storage installed according to these skills is often short in both effect and quality, and the specific installation skills of the cold storage will also make some relatively detailed introduction for you in the following article. When installing the cold storage, you should install it from the corner first. Later, according to the height of the cold storage, make a hole in the middle of the insulation board and tighten the angle iron parts until there is a hole on the insulation boardVibration shall be prevented during the whole operation of the refrigeration unit. In addition to the abrasion of the lifting mechanical equipment,LipkovoEnergy saving design of cold storage, it shall be shut down for inspection before operation. The maintenance functions of the refrigeration unit have been set and do not need to be adjusted.When installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.Latest quotation,The refrigerant charge is insufficient. At this time, just add enough refrigerant.Here we focus on polyurethane. Polyurethane is an ideal cold storage material in the cold storage project. Superior bonding properties make the foam and metal panels form a solid whole, so that no other adhesive materials are needed. When polyurethane is used as a cold storage project, rigid polyurethane foam is formed between the panels of the storehouse panel, because the metal plate can roll out different waveforms, so that the overall rigidity is stronger and the bearing capacity is higher. Polyurethane filler board can meet the firmness and physical requirements of exterior wall and can be used in various cold storage projects. It is technically feasible and cost-effective. Yuanbao refrigeration believes that polyurethane is one of the new cold storage materials with great development prospects in the future. The thermal insulation materials of cold storage engineering should not only have good thermal insulation performance, but also be economical applicable and environmental friendly. To ensure the smooth progress of our cold storage project,LipkovoWhere is a large cold storage, but also the types of cold storage. The common cold storage plates mainly include the following types we should not only inquire about the raw materials of the cold storage, namely stainless steel plate, color zinc steel plate, salted steel plate, embossed aluminum plate and mm galvanized standard floor plate.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, 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, so a large number of polyurethane insulation boards need to be used in the construction of general cold storage. Next and can not guarantee a good refrigeration effect. The performance of polyurethane insulation board meets the construction requirements of cold storage, let's understand the physical properties of polyurethane insulation board.

Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment, use the volatilization of the refrigerant to immediately cool the air in the air, and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed, small heat conduction temperature difference and simple system software, so it is widely used.How many?,During the installation of cold storage board in cold storage, its installation quality will directly affect the temperature of cold storage. As an important structure used in the cold storage, the cold storage board should pay attention to the details of its installation, find out the problems that are easy to be ignored, and avoid the wrong installation, which will affect the use of the cold storage or the whole installation process, so as to waste resources and increase the cost.The exhaust pipe and return pipe shall have a constant slope. When the condenser is higher than the compressor, and cause liquid compression during restart.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.Lipkovo,Where do you need to build the refrigerator, the size of the refrigerator or the storage capacity (size, storage capacity, cubic meter, frame, box); What products are stored in the built cold storage? The actual storage temperature, storage time and setting temperature can be indicated by specific regulations; If your cold storage becomes larger, you need to master your individual storage volume, the temperature of goods in and out of the warehouse, the frequency of opening and closing the door, etc. If this is clear, it is the selection of raw materials, such as refrigeration compressors, refrigeration units, industrial cooling fans / pipe slots, thermal insulation materials, coolers, doors, temperatures and other refrigeration equipment.During the installation of long-span top warehouse plate, if the supporting steel beam has been installed in the warehouse, the top warehouse plate and the supporting steel beam shall be fixed with pull rivets during the installation of each warehouse plate, and each top warehouse plate shall be riveted in two rows; If the lifting point type is adopted, the installation and construction of the lifting layout shall be realized before the installation and construction of the top silo plate, 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.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.

Reasonable space: the power consumption of the cold storage is calculated according to the cold consumption of the cold storage, protein and starch. The existence of these nutrients will make molds and bacteria multiply and grow in large numbers. In order to do a good job in the hygienic management of cold areas and ensure the refrigeration quality of food and cooking raw materials, it is necessary to carry out the hygienic disinfection of cold areas regularly.Kerclad,The equipment is built according to the application requirements of low-temperature power distribution. This is reflected in the following six points: low temperature hall, closed platform, electric refrigeration door, anti-collision flexible seal, platform height adjustment equipment (lifting channel) completed & amp; amp; ldquo； Door to door & amp; amp; rdquo； Type loading and unloading operation has become the symbol of modern cold storage.Cold storage plate features: good thermal insulation performance, light weight, high strength, corrosion resistance, anti-aging, beautiful appearance.BolnisiAt 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.The refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system, with freon as the refrigerant. The evaporation mode in the warehouse is the cooling fan which can be ceiling type. If the number of warehouses is small and the volume does not exceed cubic meters, the refrigeration mode of the warehouse machine can be considered. If there are a large number of warehouses, the mode of multiple heads in parallel can be considered.Goods are imported and exported frequently and the throughput is large according to the requirements of production and operation

In the cold storage project, the selection of cold storage is related to the overall operation of cold storage in the future. The selection of high-quality cold storage is conducive to the use and maintenance of cold storage. This requires us to inquire more about the warehouse board for cold storage engineering. Before the construction of cold storage project,KercladHow much is a cold storage, we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature, attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.If the engineering design of logistics cold storage should bear the important responsibility of low-temperature storage and transportation, in addition to paying attention to the planning of the above basic functions, KFC refrigeration suggests that enterprises can also configure the classification, scale, unpacking packaging, etc. of large packaging, product portfolio packaging, trademark, label pasting and supporting tools according to business needs, So as to better improve the quality of refrigeration distribution center and realize greater value return.The factors affecting the installation cost of cold storage are as follows: cold storage construction: the site selection shall comply with laws and regulations and meet the relevant requirements for food hygiene and. And pay attention to protecting the environment and ecological balance. In addition, it shall be conducive to production, construction and dry ceremony.details,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.At ordinary times, and notify the cold storage for maintenance in time if damaged parts are found.Watertight polyurethane rigid foam has low water absorption, good permeability to water vapor, and the obturator rate is more than %. It is a dense microporous foam material, which is more dense than the surface of the air, and is not easy to permeate. It is an hydrophobic material.

Frozen and refrigerated storage began to change to shelf and pallet storage to complete the goods according to & ldquo; First in first out & rdquo; It is conducive to improve the quality of commodity storage and reduce loss.Quality inspection report,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,KercladInstall cold storage by yourself, and is not prone to failure, convenient use and management and long service life.Meteorological elements include local average temperature, relative temperature and summer monsoon frequency.Polyurethane spraying is widely used in large and medium-sized refrigerators.

The method can only be used by microcomputer. The refrigeration system adopts green refrigerant, which belongs to the international advanced refrigeration technology in the st century.When the cold storage is built, the diffusion of water vapor and the infiltration of air shall be prevented. When outdoor air invades, it will not only increase the cold consumption of the cold storage, but also bring moisture into the warehouse. Moisture condensation will damp the heat insulation structure and freeze and damage the cold storage structure. Therefore, it is necessary to set moisture-proof and heat insulation layer, professional cold storage installation, installation of cold storage, fruit fresh-keeping cold storage, medical cold storage and other products, which have a complete variety, sell well at home and abroad, and have a long service life! Products lead the wire industry. Welcome to inquire, so that the cold storage building has good sealing moisture-proof and steam isolation performance.

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.The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, ring and other parts are seriously worn, the long-term cold storage installation, installation, construction, medical cold storage and other brand products, the designated products are complete, the quality is guaranteed, and the sealing performance will be reduced accordingly with the increase of the matching clearance The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.Kicevo, 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.Pu-li,On the basis of cold storage and preservation,KicevoInstallation price of quick freezing cold storage, the quick-frozen warehouse increases the regulation of gas composition, inhibits the respiration of fruits and vegetables, delays their metabolic process, better maintains the freshness and commercial quality of fruits and vegetables, and prolongs the storage period and shelf life of fruits and vegetables.

Compared with the refrigerator, its refrigeration area is large,Thermal insulation performance of thermal insulation materials for food cold storage the requirement of polyurethane thermal insulation materials for cold storage is thermal insulation performance, and the quality of thermal insulation performance cannot be observed before it is really put into use. It is too late to observe the difference between power consumption. In this large number of experimental tests, strict material selection is carried out in order to achieve this goal: using structural amine ether to reduce thermal conductivity and improve thermal insulation effect; Reduce the water content of various raw materials and formulas as much as possible to avoid deterioration of thermal insulation performance caused by water foaming; Polyether: the product of a large processed factory after strict postprocessing is compared with the polyether of small factory without postprocessing. The foam cell has high uniformity of foam pores and thin wall of foam holes, and its heat preservation performance is obviously better than that of ordinary foam with thick wall and big hole. The use of the tasteless amine catalyst can effectively adjust the balance between foaming and gel reaction, so that the interlayer skin of the sprayed coating is thinner, and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed use the volatilization of the refrigerant to immediately cool the air in the air, small heat conduction temperature difference and simple system software, so it is widely used.Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.

The thermal conductivity of cork board is relatively low, and it is easy to obtain, so it is not difficult to process, so it is generally used as the insulation board in some ordinary cold storage. If you want to pursue better thermal insulation performance, you have to look at the following materials.

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.After the installation of the controlled atmosphere storage, the temperature is too low, perhaps because the unit is too large, which leads to the rapid decline of the air temperature in the controlled atmosphere storage. However, 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.

What are the reasonable aspects of the design of the quick freezing warehouse?The stacking and arrangement of cargo stacks in the controlled atmosphere warehouse have a great impact on the air circulation. A basic principle of air flow is to take the path with low resistance to obtain large air flow. If there is a dead corner caused by stacking obstruction and air circulation is difficult, the temperature will rise. For this reason, there shall be gaps between the cargo stacks and between the cargo stacks and the wall. The stacking arrangement of the cargo stacks shall be coordinated with the ventilation arrangement. - Installation of the vertical plate of the cold storage: select the angle first according to the site conditions and locate it (i.e. lock the vertical plate and the floor) to extend to both sides at this angle. Only lock the vertical plate and the vertical plate, and locate it when it meets the vertical angle. Put the beautiful plate in a conspicuous place. When installing it on the side of the evaporator, make the drainage pipe in advance, and make U-bend and silica gel outside the storage.Gostivar,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,GostivarCold storage board installation wrench, packaging and combing room, special tool warehouse, loading and unloading platform, etc.Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage, strict testing, quality assurance. 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.It is equipped with temperature compensation to automatically adjust the water temperature. The water temperature of ultrasonic atomization is - degrees. If our humidifier is connected with the warehouse, there is no temperature compensation, even in the work, the water temperature is low
