[0002] Cold storage is a kind of refrigeration equipment. Cold storage refers to the use of artificial means to create an environment with different temperature or humidity from the outdoor environment. It is also a constant temperature and humidity storage equipment for food, liquids, chemicals, medicines, vaccines, scientific experiments and other items. Cold storage is usually located near the transportation port or place of origin. Compared with refrigerators, cold storage has a larger refrigeration area and shares the same refrigeration principle. Cold storage has always been an important part of the logistics industry. Cold storage is mainly used for constant temperature and humidity storage of semi-finished and finished products such as food, dairy products, meat, aquatic products, poultry, fruits and vegetables, beverages, flowers, green plants, tea, medicines, chemical raw materials, electronic instruments, tobacco, alcoholic beverages, etc. Cold storage is a kind of refrigeration equipment. Compared with refrigerators, its refrigeration area is much larger, but they have the same refrigeration principle. Among them, ultra-low temperature cold storage generally has a temperature of -40°—-80°, and is mainly used for low-temperature refrigeration of seafood, chemicals and other products.
