Abstract

PURPOSE:To shorten the defrosting operation of the titled air conditioner and accelerate the rise-up thereof after defrosting by setting the rotational speed of an electrically-driven compressor to a value higher than the set rotational speed computed on the basis of the room temperature and the room temperature set value during the defrosting operation and within a predetermined period of time after or before that at the time of heating. CONSTITUTION:The coolant discharged from the compressor during the heating operation is circulated in the sequence of four-way valve 1a, indoor heat exchanger 5, voltage reducing device 4 and outdoor heat exchanger 3. During the heating operation, when an AND condition is established between a signal from a defrosting timer contained in a microcomputer 8 and a signal from a defrosting thermostat 19 detecting the temperature of the outdoor heat exchanger 3, the rotational speed of the compressor motor 2 is increased up to the maximum rotational speed while continuing the heating operation by the operation of the microcomputer 8 and the inverter unit 14. After the motor 2 reaches the maximum rotational speed, the four-way valve 1a is changed over, to shift the freezing cycle to the defrosting operation.
