The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0088] The compressor 201 compresses the low-temperature and low-pressure refrigerant gas and discharges the high-temperature and high-pressure refrigerant gas. The discharged refrigerant gas flows into the outdoor heat exchanger 202 .

[0089] The outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0090] The throttling device 204 expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the outdoor heat exchanger 202 into a low-pressure liquid-phase refrigerant.

[0091] The indoor heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 201 .
