PURPOSE:To make it possible to regulate the degree of superheating of a refrigerant to a target degree of superheating by a simple construction by regulating the number of revolutions of a compressor on the basis of a temperature deviation of a detected temperature of air regulated through an evaporator from a target temperature thereof and by regulating the opening of an expansion valve on the basis of a humidity deviation of detected humidity of the regulated air from target humidity. CONSTITUTION:In cooling dehumidifying equipment, a discharge refrigerant of a compressor Cmp is circulated in the sequence of an oil separator Osp, an outdoor-side condenser Cd, an expansion valve Ex, an indoor-side evaporator Ev and an accumulator Acc, and air SA of which the temperature and humidity are regulated in the evaporator Ev is sent out by an air supply fan SF. In this case, the amount of change in the number of revolutions is computed 2 on the basis of a deviation of the temperature of the air SA detected by a temperature sensor 1 from a target temperature, and based on the computed value, the number of revolutions of the compressor is changed through the intermediary of an inverter 3. Besides, the amount of operation for change in the opening of the expansion valve Ex is computed 5 on the basis of a deviation of the humidity detected by a humidity sensor 4 from target humidity, and based on the computed value, the expansion valve Ex is controlled. |
