Specifically, the operation of the compressor, the upper fan 300, and the lower fan 500 is controlled by the controller. Wherein the upper fan 300 is operated at a low speed, and can supply air to the evaporator 100, and the evaporator 100 absorbs heat of the supplied air, so that condensed water is generated at the evaporator 100. At this time, the exhaust temperature is not high, the temperature of the condenser 200 is not high, excessive heat dissipation of the condenser 200 is not needed, and the lower fan 500 operates at a low rotating speed, so that the power of the lower fan 500 can be reduced, and the power consumption can be reduced.
