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 can be reduced, the refrigerant is condensed into liquid, and then the refrigerant is evaporated and absorbs heat, and the continuous refrigeration can be realized by the circulation. The compressor acts as a heart throughout the refrigeration system, a process that provides energy compensation. The condenser and the evaporator are two heat exchangers, the former makes the gas of the high-pressure refrigerant emit heat and convert into liquid; the latter absorbs heat from the liquid of the low-pressure refrigerant and converts it into a gas. The refrigerant becomes the delivery vehicle of heat energy in cyclic reciprocating process, in order to guarantee the temperature in the freezer in the refrigerated in-process to freezer refrigeration, refrigeration plant often need open for a long time, and refrigeration plant's long-time opening can undoubtedly increase the consumption of electric power and hydroenergy, causes the energy waste easily.
