It 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.Goods are imported and exported frequently and the throughput is large according to the requirements of production and operationPrevin,Air tightness test: system air tightness test,PrevinInstallation price of cold storage, also known as leak detection process, is the last link of commissioning. This work can be divided into pressure, vacuum and ammonia filling leak detection stages.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, 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,The bacterial action of acid disinfectants is mainly to coagulate the protein in the bacteria. Common disinfectants include lactic acid, bleach, formalin, etc. Specifically, after the fish comes out of the freezer, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below degrees Celsius. Then, according to the volume of ~ grams per cubic meter volume of the frozen storeroom the storeroom door is closed tightly with the sprayer, so that the vinegar evaporates and flows in the storehouse and the blower is started intermittently, which makes the vinegar absorb a lot of fish smell.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, installation, construction, fruit preservation, 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, 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.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. All buttons, electrical switches, etc. shall be reliable safe, long-term cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, old brand price advantage and quality guarantee! Easy to identify and operate. The indicator light shall be simple and clear. The device and each switch shall be installed on the upper side outside the warehouse door, which is easy to operate, read data and not easy to be damaged, and the height of the bottom edge of the switch box is about mm.

Simple refrigeration is based on the volatilization of refrigerant in the condenser of the cold storage, so as to cool the refrigerant, and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed, large total heat conduction temperature difference and complex system software, so it can only be used in less places, such as brine ice making and cold storage with constant temperature requirements.Selection of refrigeration unit in cold storage: the selection of cold storage system software is mainly the use of refrigeration compressor and air conditioning evaporator in 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 lowproduction costs,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, it may even make the cold storage unusable. Therefore,PrevinCold storage engineering installation design, 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 building structures are vulnerable to. Therefore, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.The bacterial action of acid disinfectants is mainly to coagulate the protein in the bacteria. Common disinfectants include lactic acid, bleach, formalin, etc. Specifically, after the fish comes out of the freezer, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below degrees Celsius. Then, according to the volume of ~ grams per cubic meter volume of the frozen storeroom, the storeroom door is closed tightly with the sprayer, and the blower is started intermittently, so that the vinegar evaporates and flows in the storehouse, which makes the vinegar absorb a lot of fish smell.The service life of the cold storage depends on the quality of the refrigeration equipment, but it also has a great relationship with the proper daily management and maintenance after the installation of the cold storage. Many times, as long as we maintain and maintain the cold storage regularly, we can greatly improve the service life of the cold storage and reduce the cost.

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.Quality improvement,Energy saving and power saving: the design cost of quick freezing warehouse mentioned above is very low, but it has a great impact on the cost of quick freezing warehouse and later use cost. The electricity bill is often an important expenditure item in the later stage. The design scheme of the show can greatly reduce the power consumption of the quick freezing warehouse. The selection of the back sunny side of the quick freezing warehouse, the selection of the thickness of the thermal insulation board should be appropriate, the tightness of the quick freezing warehouse door, and the temperature difference between the adjacent cold storage rooms should not be too large are all issues that we need to consider. There are also some tips, such as the use of air curtain machine on the quick freezing warehouse door. We remind users to use parallel units in quick freezing warehouse as far as possible and start them reasonably.The tightness of water valve and brine valve, the replacement of sealing ring, the flexibility of valve, and disassembly and cleaning if necessary.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.Previn,The combined cold storage door starts frequently or does not start for a long time, or does not stop for a long time, or stops before the storage temperature reaches.Cork board: cork board can be said to be a relatively primitive kind of cold storage. 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.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,PrevinWhich company is better to install cold storage, the ground will be broken and the whole building structure will be deformed. If the damage is serious, it may even make the cold storage unusable. Therefore, 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, especially in the process of periodic freezing and thawing cycle, building structures are vulnerable to. Therefore, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.
