る制御手段を設けた ことを特徴とするヒートポンプ式調和装置。[Scope of claim for utility model registration] During heating operation, the refrigerant on the outdoor heat exchanger side is circulated to the indoor heat exchanger through a four-way valve, and during defrosting operation, the four-way valve is switched to circulate the refrigerant on the indoor heat exchanger side. In a heat pump air conditioner equipped with a compressor whose capacity can be adjusted to circulate refrigerant to the outdoor heat exchanger, the capacity of the compressor is reduced when performing the defrosting operation, and then the four-way valve is operated to defrost the air. A heat pump type harmonizing device characterized by being equipped with a control means for switching between operations.
