). Therefore, the refrigerant leaving the low-stage compressor (1) flows as shown by the broken line arrow: first switching valve (2) → refrigerant heat exchanger (5) → gas-liquid separator ω → refrigerant heat exchanger (5) → 2
The flow goes from the switching valve (a) to the high-stage compressor @ to the first four-way valve (4) to the water heat exchanger (9), and then the normal hot water supply operation described above (
The flow is guided to the low stage compressor (1) in the same way as when the low stage compressor (1) is operated only. Like this water heat exchanger (9)
Since the refrigerant flowing into the refrigerant is compressed by the lower stage compressor (1) and the higher stage compressor (c) (two-stage compression),
The temperature of this refrigerant is maintained at around 90℃, and the hot water storage M (6)
Heat the water inside to around 85℃. In this way, the apparatus of the present invention operates the low-stage compressor (1) during normal hot water supply, and operates the low-stage compressor (1) and the high-stage compressor (to) during high-temperature hot water supply. This was done so that they could be operated at the same time.

The refrigerant that has exited the low-stage compressor (1) flows as indicated by the solid arrow in FIG. 2, and the room is cooled by the evaporation action of the indoor heat exchanger Qη. At this time, since the water heat exchanger (9) acts as a condenser, the water stored in the hot water storage tank (6) is heated. In addition, when operating the high stage compressor (2) instead of the low stage compressor (1) to cool the room, the second switching valve (to) is held in the state shown by the dashed line, and this high stage compressor (2) is operated instead of the low stage compressor (1). It is sufficient to operate the stage side compressor (to). At this time, the refrigerant discharged from the high-stage compressor passes through the discharge side pipe C3+1 to the first four-way valve (4).
