[0054] The refrigeration device in the present application generally comprises a box body, a door body and a refrigeration system, wherein at least a refrigeration compartment is formed in the box body, and the refrigeration compartment is opened and closed through the door body to meet the requirements of storing and retrieving articles.

[0055] The refrigeration system uses a compressor, condenser, expansion valve and evaporator to perform the refrigeration cycle of the refrigeration equipment. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve cooling of the items in the box.

[0056] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0057] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can cool the items in the box by utilizing the latent heat of evaporation of the refrigerant.
