The air conditioner is provided therein with a compressor, a condenser, an expansion valve, and a heat exchanger, and performs a refrigeration cycle of the air conditioner by using the compressor, the condenser, the expansion valve, and the heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and heat exchange, 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 condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The heat exchanger exchanges heat of the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The 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.
