The working principle of the refrigerating system is as follows: the compressor 106 is driven by a motor as power of the refrigeration cycle to continuously rotate, thereby compressing the low-temperature low-pressure refrigerant vapor to a high-temperature high-pressure state. The condenser is a heat exchange device that uses an ambient cooling refrigerant to remove heat from the high-temperature, high-pressure refrigerant vapor from the compressor 106, thereby cooling and condensing the high-temperature, high-pressure refrigerant vapor into a high-pressure, normal-temperature refrigerant liquid. The refrigerant liquid at high pressure and normal temperature passes through the capillary tube 300 to obtain low-temperature and low-pressure refrigerant, and then is sent into the evaporator 200 to absorb heat and evaporate. The evaporator 200 serves as another heat exchange device, and the throttled low-temperature low-pressure refrigerant liquid is evaporated therein to be vapor, absorbs ambient heat, and reduces ambient temperature for refrigeration purposes. The evaporator 200 is configured to provide cooling directly or indirectly to the storage compartment.
