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.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?Tamisari,It takes hours after the installation of the controlled atmosphere warehouse to deposit the goods, so as to quickly meet the temperature required by the goods and ensure that the controlled atmosphere warehouse equipment can operate normally.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.Huizen,Moreover, polyurethane does not produce harmful gas at high temperature.It will still decrease. The humidification amount will decrease by % at degrees.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, playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?

Fault phenomenon: high current or tripping during unit startup, and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be ~ seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; TR time relay is broken (relay unit).The air suction surface of the condenser shall be kept more than mm away from the wall, and the air outlet shall be kept more than m away from obstacles.Features of quick freezing warehouse: the quick freezing technology is advanced, the frost free quick freezing method is adopted, the famous brand compressor and refrigeration accessories are configured, and the automatic frost is adopted. 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.Which one is better,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.General quick-frozen warehouses are mostly cooled by refrigeration mechanisms,TamisariInstallation price of small cold storage, 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.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.

Moreover,During the installation of polystyrene storehouse,TamisariInstallation of small fruit cold storage, the Perpendicularity Error of wall plate shall be corrected while the top storehouse plate is installed. The length of the top warehouse plate shall be mm shorter than the surface of the wall plate. After the installation of the top warehouse plate, the mm gap shall be marked with foaming material to ensure the sealing performance of the warehouse body.According to the changes of external conditions, the air-conditioning fresh-keeping warehouse in the machine room can automatically and accurately adjust the operation of the equipment, so as to maintain the required refrigeration conditions and improve the economy of the operation of the fresh-keeping warehouse.Install the electric control system. The electric control system of the cold storage mainly includes electric controller, electric door, lighting and other electrical equipment in the cold storage. The power supply of the cold storage is required to be stable phase line,TamisariWhere is the installation of cold storage cheap, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.Tamisari,The cold storage belongs to a kind of refrigeration equipment. Compared with the refrigerator, its refrigeration area is large, but they have the same refrigeration principle. So how to maintain the cold storage every day. Today I'll introduce how to do a good job in the daily management and maintenance after the installation of the cold storage.Secondly, since the cooling of the compressor is not continuous, the multi work operation at night can be selected if possible. When working at night, the external temperature is low, the cooling water temperature is reduced, and the condensation pressure and condensation temperature are reduced. The cooling capacity of the sampling system coupled with the equal role of the cold storage board, reduces the power operation of the compressor and achieves the purpose of energy saving.The importance of regular oil discharge, descaling and air discharge in the refrigeration system of the warehouse.
