Abstract

PURPOSE: To keep a continuous operation while restricting the lowering in operating efficiency even in the case of an abnormal state of a sensor for judging a starting time of a defrosting operation based on the variation in integrating capability.
CONSTITUTION: Temperature differences between the temperature of an indoor heat exchanger 6 detected by an indoor heat exchanger sensor (The) and the sucked air temperature in an indoor heat exchanger 6 detected by a suction air sensor (Thr) are integrated in response to time and a starting time of defrosting operation is judged on the basis of the variation of the integrating capability. Provided that when an integrated heating operation time reaches its upper limit value, it is judged as a starting time of the defrosting operation. When the suction sensor (thr) is in an abnormal state, judgement by the integrating capability is not performed and as the integrated heating operation time reaches a specified value, it is judged to be a starting time of the defrosting operation.
