PURPOSE:To enable the increase of a heat pump in an air conditioner and to recover heat by providing an outdoor auxiliary heat exchanger in series with an outdoor air heat exchanger to enable separate control of medium flows thermally exchanged from both the exchangers. CONSTITUTION:A heat pump cycle is formed by using a compressor 1, a four-way valve 2, an indoor heat exchanger 3, a throttle 5, and an outdoor air heat exchanger 11, etc. An outdoor auxiliary heat exchanger 6 is provided in series with the heat exchanger 11 for controlling separately the flows of media 7, 12 thermally exchanged from both the exchangers 6, 11. |
