Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

The refrigeration cycle of the air conditioner consists of a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle circulates through a series of processes consisting of compression-condensation-expansion-evaporation, and the hot air exchanges heat with the low-temperature refrigerant, and then low-temperature air is supplied to the room.

The compressor compresses and discharges the refrigerant gas in a state of high temperature and high pressure, 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 liquid refrigerant in the high-temperature and high-pressure state condensed in the condenser to the liquid refrigerant in the low-pressure state. The evaporator evaporates the refrigerant expanded in the expansion valve. The evaporator uses the latent heat of vaporization of the refrigerant to achieve a refrigerating effect by heat exchange with the object to be cooled, and returns the refrigerant gas at low temperature and low pressure to the compressor. The air temperature of the indoor space can be controlled through this cycle.

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