The refrigeration cycle of an air conditioner consists of a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle repeats a series of processes consisting of compression-condensation-expansion-evaporation, and after heat exchange between high-temperature air and low-temperature refrigerant, low-temperature air is supplied to the room.

The compressor compresses and discharges the refrigerant gas in a high-temperature and high-pressure state, and the discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase and releases heat to the surroundings through the condensation process. The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into the low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve. The evaporator uses the latent heat of evaporation of the refrigerant to achieve a refrigeration effect by heat exchange with the object to be cooled, and returns the refrigerant gas in the low-temperature and low-pressure phase to the compressor. Through this cycle, the air temperature in the indoor space can be adjusted.

The outdoor unit of the air conditioner refers to a part of the refrigeration cycle consisting of a compressor and an outdoor heat exchanger. The expansion valve may be located in either an indoor unit or an outdoor unit, and the indoor heat exchanger is located in an indoor unit of the air conditioner.

The present invention relates to an air conditioner for cooling an indoor space, wherein an outdoor heat exchanger serves as a condenser and an indoor heat exchanger serves as an evaporator.
