The cold room air cooler is the preferred form of small-scale cold storage, which has the advantages of simple, compact, easy installation, convenient operation, less auxiliary equipment and so on. Generally, the color steel plate is used as the panel, and the rigid polyurethane foam is used as the thermal insulation material. The storehouse has the characteristics of good rigidity, high strength, good heat insulation performance, and flame retardance. In general, the small-scale cold storage adopts eccentric hook connection of embedded parts in the plate wall or field foaming fixation, with good sealing, convenient installation, removal and handling, a small amount of field construction and installation, labor-saving, good quality, and quick effect. It can meet the needs for different purposes and is suitable for various industries and departments.
Cold storage, generally refers to facilities that use various cold room refrigeration equipment, such as cold room air cooler, condensing unit for cold room and so on to cool, control and maintain stable low temperatures. Its basic components are refrigeration system; electric control device; storehouse with certain thermal insulation performance; attached buildings, etc. The refrigeration system mainly includes all kinds of refrigeration equipment. The refrigeration equipment is the heart of the cold storage, which makes the cooling capacity and ensures the supply of cold source in the warehouse. The electronic control device is the brain of the cold storage, which commands the refrigeration system to ensure the supply of cooling capacity. The storehouse with certain heat insulation performance is the place for storing fresh agricultural products. Its function is to keep the stability of the low-temperature environment. Generally speaking, the heat insulation performance is called heat preservation. The good heat insulation structure of the warehouse can keep the cooling capacity of the refrigeration equipment manufacturers in the warehouse to the maximum extent and leak out less. On the contrary, it is to minimize the heat leakage out of the warehouse to the warehouse, which is also the main difference between the cold warehouse and the general house.
