General quick-frozen warehouses are mostly cooled by refrigeration mechanisms, so as to absorb the heat in the warehouse so as to achieve the purpose of cooling and reduction.Cold storage construction: which one is suitable for you? Which one is suitable for you?Soletracy,Replace the refrigeration oil. After years of service, the refrigeration oil inside the compressor shall be replaced. The oil stain copper filings, iron filings and impurities caused by secondary wear are mixed in the refrigeration system, which thickens the refrigeration oil, deteriorates the fluidity and performance, reduces the effect, increases the burden of the compressor, and the current will be higher than that of the new machine, This is a bad phenomenon. Replace the refrigerant oil regularly and timely to maintain the good performance of the system, so as to ensure the long-term use of the equipment.The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity, and there are corresponding strict requirements for the wall, ceiling, ventilation, disinfection and epidemic prevention of the warehouse. The refrigeration system adopts full-automatic microcomputer electrical technology and does not need to be on duty. It mainly stores western and Chinese grass materials and instruments, and can monitor and record the temperature and humidity in the storage area.Baardheere,During the use of the goods yard medical cold storage project, the stored goods must be in strict accordance with the relevant regulations. The goods should have a certain distance from the ground and wall of the cold storage. When stacking, the distance between the goods and the goods must be cm. At the same time, the distance between the goods and the cold fan should also be cm. No goods can be stored within this range, This is also an important content in the use of medical cold storage engineering.Whether the water pump works normally and whether the moldy switch is effective. In case of abnormality, timely handle the overhaul and maintenance of the refrigeration compressor in the cold storage: generally, oil separator shall be installed for semi sealed or fully sealed compressor, and an appropriate amount of oil shall be added in the oil. When the evaporation temperature is lower than - ℃, gas-liquid separator and an appropriate amount of refrigeration oil shall be added.The foaming technology of polyurethane with strong stability 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, under the unfavorable local temperature and humidity conditions, it can bear various internal and external combined loads such as wind force, self weight and normal collision, and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.Energy costs,The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam, 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.First,SoletracyWhere is the cold storage installed, use a hammer to pad the wood on the polyurethane warehouse board between the two warehouse boards, so as to make the boards closely close to each other. Two sets of connecting pieces shall be wedged between the wall panel and the wall panel, and the two sets of connecting pieces shall be fixed on the upper,SoletracySmall cold storage installation company, outer and lower sides of the gap between the wall panel and the wall panel respectively. The lower connecting piece shall be as close as possible to the lower side, so that the post cast concrete can cover the connecting piece. After the gap between the plate and the plate ground is wedged with a connector, it shall be about mm wide. If it does not meet the requirements, remove the plate trim the plate edge, and then reinstall it to make the plate joint meet the requirements. When fixing the adapter, and fix them with rivets. The spacing of the adapter should be able to tension the two library plates. When wedging the wedge iron, the hammer shall be perpendicular to the wedge iron to prevent damaging the warehouse plate. The ground wedge iron at the upper and lower parts shall be wedged at the same time,SoletracyWhere does the cold storage installation sell, and the wedge iron shall be fixed with rivets.General quick-frozen warehouses are mostly cooled by refrigeration mechanisms, and those with very low gasification temperature are used as coolant to evaporate under low pressure and mechanical conditions, so as to absorb the heat in the warehouse, so as to achieve the purpose of cooling and reduction.
Indirect cooling is that the air in the warehouse is pumped into the air cooling device by the blower. The air is absorbed by the evaporation pipe circling in the cooling device, and then sent to the warehouse for cooling. The advantages of air cooling are rapid cooling, uniform temperature in the warehouse, and can bring harmful gases such as carbon oxide out of the warehouse during storage.Application process,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.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, there may be fluorine leakage due to long-term non use, so refrigeration operation should be carried out at this time.Goods are imported and exported frequently and the throughput is large according to the requirements of production and operationSoletracy,The refrigerant charge is insufficient. At this time, just add enough refrigerant.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 structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, rapid and movable, but the project cost is relatively high.
