有していることを特徴とする空気調和機。 The discharged gas refrigerant from the compressor 1 is transferred to the indoor heat exchanger 5.
, 6 to the outdoor heat exchanger 2 for heating operation, the outdoor heat exchanger 2
a frosting amount detecting means 40 that detects the amount of frosting on the surface, and a frosting device that issues a defrosting start signal when the detected frosting amount exceeds a reference value, and a defrosting end signal when the detected frosting amount reaches a return value. Comparison means 72 and operation control means 60 which switches from heating operation to defrosting operation when a defrosting start signal is input, and ends the defrosting operation and restarts heating operation when a defrosting end signal is input.
and a forced return means 73 for issuing a defrosting end signal to the operation control means 60 when the duration of the defrosting operation reaches a reference time, and a forced return means 73 for issuing a defrosting end signal to the operation control means 60 until the first priority time elapses when starting the heating operation and restarting the heating operation. The heating priority means 71 prevents the defrosting start signal from the frost amount comparison means 72 from being input to the operation control means 60, and the first defrosting operation after the start of the heating operation is performed immediately after the first priority time elapses. and a forced signal generating means 74 for generating a forced defrosting signal when the defrosting operation is terminated by the defrosting end signal from the forcible return means 73; and a forced defrosting operation switching means 75 that issues a defrosting start signal after the restarted heating operation continues for a second priority period shorter than the first priority period. harmonizer.
