本発明はエンジン駆動ヒートポンプ冷暖房装置の改良に
関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in an engine-driven heat pump air conditioning system.

う欠点があった。BACKGROUND ART Conventionally, heat pump air-conditioning systems have had the disadvantage that their performance decreases and frost forms on the outdoor heat exchanger when the outside temperature is particularly low when operating in the heating mode.
そこで、上記の欠点を排除して加熱能力の増強をはかる
ため、補助電気ヒータ付のヒートポンプ式冷暖房装置に

この場合、冷媒加熱の熱源に電気ヒータを用いるため、
装置全体のシステム効率、即ち能力と入力エネルギーと
の比率が著しく低下するという欠点があった。Therefore, in order to eliminate the above-mentioned drawbacks and increase the heating capacity, a heat pump type air-conditioning device with an auxiliary electric heater was devised in Japanese Utility Model Publication No. 56-2134.
In this case, since an electric heater is used as the heat source for heating the refrigerant,
There was a drawback that the system efficiency of the entire device, that is, the ratio of capacity to input energy, was significantly reduced.

スポンプの駆動エネルギーが必要という欠点があった。In addition, some engine-driven heat pump devices use the engine recovered waste heat as heat for transporting refrigerant, but in this case, an actuating device called a gas pump is used.
However, since engine waste heat can be used for the high-pressure side of the heat pump, it is much more energy efficient than systems that use it for the low-pressure side. However, the drawback was that it required energy to drive the gas pump.
