るエンジンヒートポンプ。 In a refrigeration cycle that has a compressor driven by the engine, an on-off valve that closes when the engine starts and warms up is installed, and the refrigerant suction pressure is applied to the suction side of the compressor. An engine heat pump characterized in that a refrigerant pressure detection device is installed which outputs a valve opening signal to the opening/closing valve when the pressure falls below a certain value.
