ことを特徴とするヒートポンプ式空気調和機。 A heat pump air conditioner that is equipped with an inverter-driven compressor, a four-way switching valve, an indoor heat exchanger, a throttling device, and an outdoor heat exchanger, and whose capacity is controlled by changing the rotation speed of the inverter-driven compressor according to the load. The compressor is provided with a bypass capacity control mechanism for bypassing the gas during the compression stroke to its suction side and controlling its capacity, and also detects the load and adjusts the load to the minimum capacity by changing the rotational speed of the compressor. 1. A heat pump type air conditioner, characterized in that a heat pump type air conditioner is provided with a control means for activating the bypass capacity control mechanism when the load becomes less than or equal to the load.
