特徴とするヒートポンプ式空気調和機。 During heating operation, the heat pump type air is equipped with a crankcase heater that is energized to heat the compressor when the compressor stops, and an indoor fan that starts operating when the temperature of the indoor heat exchanger rises above a standard value. The conditioner is provided with means for energizing the crankcase heater during defrosting operation and after returning to heating operation after the defrosting operation is completed until the temperature of the indoor heat exchanger reaches the reference value. A heat pump air conditioner featuring:
