The refrigerant charge is insufficient. At this time, just add enough refrigerant.Cold storage is mainly used for frozen processing and storage of foodLopez Matos,After the fresh-keeping storehouse is built, it is also important to pay special attention to the maintenance of fresh-keeping storehouse equipment in the whole process of application. Here are some key maintenance matters.If 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.Borjega,There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.During production in the production workshop, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project, not less than & plusmn; kg/m.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.

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, the logistics center cold storage cold chain for the purpose of product distribution came into being and developed rapidly, playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?Whether it is a fruit fresh-keeping warehouse or other cold storage, there are many details to pay attention to in the transformation of the cold storage. If other small items are not done well it will bring a lot of trouble to the later use, such as high energy consumption and small problems.A large number of personnel are not allowed to select goods in the warehouse. Close the warehouse door in time. When the warehouse door is opened,Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, 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.The overall construction achievements of the cold storage project have been put into use, and the service life can reach years.In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank.

The spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed,Lopez MatosPharmaceutical plant,Lopez MatosHow much is the cold storage installed per square meter, the wall panel joints shall be evenly sealed and decorated with silicone sealant.Discount,Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops,Lopez MatosInstallation of large and small cold storage, it shall be solved in time to avoid adverse effects.Before the installation of the controlled atmosphere warehouse, we should also know how long the time demand for freezing goods is. After the installation of the controlled atmosphere warehouse, it can be divided into fresh-keeping warehouse, cold storage, frozen storage and quick-frozen storage. The first thing for the fresh-keeping warehouse is to store regular items, the first thing for the cold storage is to store items below zero, and the first thing for the frozen storage is items around zero, The freezing time code takes hours. If it is put into the quick freezing warehouse, it only takes to hours to reach the phenomenon of quick freezing. In the process of depositing goods, if the temperature is too low, it will affect the normal temperature of the deposited goods. The high price cold warehouses of various specifications are installed, installed, fruit fresh-keeping cold warehouses, and medical cold warehouses are supplied in time, High cost performance, has become the preferred brand for many wire products, 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.Lopez Matos,During the installation of polystyrene storehouse, 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.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, and unqualified products are not allowed to leave the factory.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.
