The lower the temperature, the higher the frequency the compressor needs to operate to increase the refrigerant circulation volume; the expansion valve needs to increase the opening to allow more low-temperature refrigerant to enter the evaporator to absorb heat.

[0112] In this embodiment, the condenser needs to cool the high-temperature and high-pressure refrigerant discharged from the compressor into a liquid state.
