The cold storage is one of the best modes for storing products which are easily influenced by the environmental temperature at present, and most of the mechanical cold storage in China mainly adopts a steam compression type refrigeration mode to adjust the temperature of the cold storage at present. The mechanical refrigerator is simply a refrigerator that performs cooling by a mechanical method. The refrigeration principle can be briefly described as follows: the evaporation of the liquid refrigerant with lower vaporization temperature is utilized to absorb the heat in the storage environment, thereby reducing the temperature of the storage. The vaporized refrigerant is sucked back and pressurized by the compressor, the refrigerant transfers the absorbed heat to the cooling medium in the condenser, so that the temperature of the refrigerant is reduced and the refrigerant is condensed into liquid, and then the evaporation and the heat absorption are carried out, and the continuous refrigeration can be realized by the circulation.

However, when power failure occurs, the refrigerator loses power input, the refrigerating device cannot refrigerate, the temperature in the refrigerator rises due to long-time incapability of refrigerating, the articles stored in the refrigerator begin to recover to the room temperature, and the articles originally stored in the refrigerator are easy to deteriorate due to moisture generated by thawing.
