The temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.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.Drashkin,The gap between the cooling fan and the storage plate shall be greater than the thickness of the cooling fan.The three-dimensional automatic cold storage adopts a computer, which can complete the loading, unloading and stacking in the storage, the control of storage temperature and the operation of refrigeration equipment.Colombia,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.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.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,DrashkinFruit and vegetable fresh-keeping warehouse, 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.

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. 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,DrashkinConstruction and installation price of cold storage, to form a vapor barrier layer.For those large-scale fresh-keeping warehouse wholesalers, if the equipment fails due to long-term neglect of maintenance, the loss can not be ignored. Therefore, we should do a good job in the maintenance of fresh-keeping warehouse wholesalers in the process of daily use.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.retailer,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, and the temperature of the tally area is usually controlled at ~ + ℃.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 so as to avoid bad compressor and reduce the service life of the compressor.It is required to set up a special tally room (area) replace it with new oil in time, 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, 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,DrashkinInstallation of cold storage equipment manufacturer, and I found that it is cheap to replicate cold through actual field investigation.Project scope,Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.Disadvantages: high precision requirements, shape and position tolerances are in micron level; No exhaust valve, and the heat in the compression process is difficult, so it can only compress the gas with small adiabatic index or internal cooling; Large displacement scroll refrigeration unit is difficult to realize. The receiving teeth are high, the displacement is large, the diameter is large, and the unbalanced rotation mass increases.The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, 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.Drashkin,Wall and floor fixtures shall start at corners. According to the plate layout drawing, transport the two plates at the corner of the required device to the device location. According to the plate beam height and the model of the angle iron for fixing the mushroom head nylon bolt, 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, 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, the angle iron parts of the warehouse plate shall be covered with a shield to avoid the high temperature of the welding ground baking the warehouse plate and welding slag on the warehouse plate during electric arc welding.As a coolant, so as to achieve the purpose of cooling.Technical assurance measures for the installation of cold storage: during production in the production workshop the production shall be carried out in strict accordance with the operation rules specified in ISO quality operation, self inspection and inspection application shall be carried out to ensure that the factory pass rate is, and unqualified products are not allowed to leave the factory.
