The compressor 151 compresses the refrigerant to a high-temperature and high-pressure state.

The compressor 151 and the condenser 160 are connected through the connection pipe 155 so that the refrigerant can be moved.

The condenser 160 condenses the high-temperature and high-pressure refrigerant compressed from the compressor 151. The condenser 160 dissipates heat generated by condensing the refrigerant. The refrigerant condensed while passing through the condenser 160 is moved to the expansion valve.

The evaporator evaporates the low-temperature low-pressure liquid refrigerant that has passed through the expansion valve. In the evaporator, the liquid refrigerant evaporates and heat exchange with the surrounding gas proceeds. The liquid refrigerant evaporates and absorbs the latent heat of the main surface, thereby generating cold air as the gas around the evaporator cools. The completely vaporized refrigerant is supplied to the compressor 151 again to circulate the refrigeration cycle.
