ζ目的と有−Ｙる。In the conventional outdoor air heat exchange device for this type of engine-driven heat pump, total heat was exchanged between the air and the refrigerant only seven times in the air-refrigerant heat exchanger, but when this was used, When an air-refrigerant heat exchanger is operated as an evaporator, the refrigerant is easily gasified in the air-refrigerant heat exchanger section located close to the radiator using the heat dissipation of the radiator, but in the air-refrigerant heat exchanger section located close to the radiator, the refrigerant is easily gasified using the heat dissipation of the radiator. In the air-refrigerant heat exchanger section located there, the heat dissipation of the radiator cannot be utilized, and the refrigerant cannot be gasified as easily as in the section close to the radiator.
It has the disadvantage that it cannot actually gasify the refrigerant.

なわれ、効率が良い。According to the configuration of the above embodiment, due to the heat radiation from the radiator (6), the fin temperature distribution of the lower heat exchange part (7B) is such that the fin temperature of the portion near the radiator (6) is different from the fin temperature of the radiator (6). However, since the lower heat exchange section (7B) acts as a heat insulating material, the temperature of each heat exchanger section (7a) in the upper heat exchange section (7A) increases. The fin temperatures are the same, and the heat exchange action, that is, the evaporation action and the condensation action, are performed in the same way in each heat exchanger section (7a) in the upper heat exchange section (7A). Therefore, during hot water generation operation, the refrigerant undergoes evaporation shift in the same way in each heat exchanger section (7a) of the upper heat exchanger section (7A) - and then radiates in the lower heat exchanger section (7B). The refrigerant is completely evaporated using the heat radiation of (6). On the other hand, during cold water generation operation, the refrigerant is condensed in the lower heat exchange section ('7B), and then the refrigerant is condensed in each heat exchange section in the upper heat exchange section (7A). The refrigerant is equally condensed in the container parts (7a) and e.In short, the refrigerant evaporates and condenses reliably and is highly efficient.
