Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa, the power consumption will increase by about . It can be seen that it is coldAs a coolant, make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage, so as to achieve the purpose of cooling.Flores,As an important support for the development of cold chain performance, the standardized construction of cold storage refrigeration system is very important. It not only helps to rationalize the energy consumption of the cold storage system, but also has an important impact on improving the low-temperature preservation quality of commodities.Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate, compressor line is disconnected, fuse is blown, thermal relay acts,FloresPharmaceutical reagent cold storage, compressor is locked, line is falsely connected or loose fault phenomenon: it stops in a short time after drying, ambient temperature is too high, condenser is blockedAl Qusiyah, every ℃ increase in the evaporation temperature of the cold storage can save energy by ~ . Therefore, on the premise of meeting the refrigeration process of the product, the liquid supply can be adjusted to increase the evaporation temperature as much as possible. - 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.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.

Establish a perfect computer network, make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union, the United States and Japan, all members of the food supply chain have the legal responsibility to implement traceability.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,FloresHow much is the cold storage installed per square meter, there may be fluorine leakage due to long-term non use, so refrigeration operation should be carried out at this time.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, the refrigeration oil and drying filter shall be replaced times after the operation of the cold storage equipment. Replacement after half a year. Depending on the circumstances.Industry managementIf there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.The spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed, the wall panel joints shall be evenly sealed and decorated with silicone sealant.There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.

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.Industry management,Anti odor floor drain shall be set on the pavement of refrigeration room and refrigeration unit room, and the height width ratio of floor drain water seal shall not be less than mm. The elevator shaft, electronic pit and other places convenient for drainage shall be provided with drainage and equipment to avoid backflow of water.The shelves in the warehouse shall have sufficient strength and rigidity.Various construction materials, such as material certificate, test report and stage acceptance record, shall be carried out simultaneously with the project construction,FloresFruit and vegetable fresh-keeping cold storage installation company, 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.Flores,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.Initial stage of cold storage equipmentThe polyurethane insulation board used in the construction of cold storage shall be integral and continuous, and there shall be no joint in the middle. The junction of polyurethane insulation board, top plate and ground shall be made into fillet arc for transition, which can well meet the health needs.
