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

The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the outdoor heat exchanger. The outdoor heat exchanger condenses the compressed refrigerant into a liquid phase, and heat is released to the ambient environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the outdoor heat exchanger into a low-pressure liquid-phase refrigerant. The indoor heat exchanger evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The indoor heat exchanger may achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. The air conditioner is used as a heater in a heating mode when the indoor heat exchanger is used as a condenser, and as a cooler in a cooling mode when the indoor heat exchanger is used as an evaporator.
