摘要： An air conditioner is disclosed. The air conditioner includes an indoor unit, a first outdoor unit including a first outdoor heat exchanger and a first compressor to be driven by electricity, a second outdoor unit including a second outdoor heat exchanger and a second compressor to be driven by an engine, a cooling water line, through which cooling water to cool the engine flows, and at least one waste heat-recovering heat exchanger for exchanging heat between refrigerant to be introduced into at least one of the first outdoor heat exchanger and the second outdoor heat exchanger and the cooling water flowing through the cooling water line. By provision of the waste heat-recovering heat exchanger, which heat-exchanges hot cooling water with refrigerant flowing through the first and second outdoor heat exchangers, frost formed on the first and second outdoor units during low-temperature heating is removed. It is possible to cope with a wide range of heating loads while achieving high efficiency, using both the electric heat pump (EHP) system and the gas engine-driven heat pump (GHP) system.
摘要翻译：公开了一种空调机。空调机包括室内机，第一室外机组，第一室外热交换器和被电力驱动的第一压缩机，第二室外机，包括第二室外热交换器和第二压缩机，由发动机驱动，通过冷却水冷却发动机的冷却水流，以及至少一个用于在被引入第一室外热交换器和第二室外热交换器中的至少一个的制冷剂之间进行热交换的废热回收热交换器，冷却水流经冷却水管线。通过设置与流过第一和第二室外热交换器的制冷剂热交换热水的废热回收热交换器，除去在低温加热期间在第一室外单元和第二室外单元上形成的霜。使用电热泵（EHP）系统和燃气发动机驱动热泵（GHP）系统，可以应对各种各样的加热负载，同时实现高效率。
