When cooling operation or dehumidifying operation is started, a blower fan for an evaporator and an exhaust fan for a condenser are driven at an initial rotational number. A compressor is driven at a fixed rotational number. Due to load variation, an operating current supplied from a power source is changed. When the operating current exceeds a reference value, the rotational number of the blower fan is gradually reduced. When an endothermic quantity by the evaporator decreases, a temperature of a gas refrigerant flowing through the evaporator is lowered. Since the load applied on the compressor is reduced, the operating current decreases. In this way, when the compressor is loaded, the operating current increased, however, by controlling operation of the fans as described above, it is possible to prevent that the power source is shut off due to overcurrent and operation is stopped.
