FIG. 1 is a refrigerant circuit diagram showing indoor unit A during cooling operation, in which refrigerant flows as indicated by solid arrows. That is, the high-pressure refrigerant gas from the compressor 1 passes through the four-way valve 2, condenses in the outdoor heat exchanger 3, passes through the check valve 7, the third on-off valve that is open, and the first on-off valve 13a, and then is used for cooling. The pressure is reduced by the expansion device 6, the air is evaporated and gasified by the indoor heat exchanger 4, and the room is cooled, and then the air is sucked into the compressor 1 again through the open second on-off valve 15b and the four-way valve 2. At this time, all other on-off valves are closed.

In this case, high-temperature, high-pressure gas from the compressor 1 passes through the four-way valve 2 and the closed second on-off valve 15b, and is condensed in the hot water supply heat exchanger 9. At the same time, the water supplied from the bathtub 20 by the circulation pump 19 is heated. Next, the condensed and liquefied refrigerant passes through a check valve 11,
First on-off valve 13b and third on-off valve 12 in open state
The pressure is reduced by the heating diaphragm 5 and evaporated by the outdoor heat exchanger 3 while absorbing heat from the outside air.
After that, it is sucked into the compressor 1 again. At this time, all on-off valves other than those mentioned above are in the closed state.

At this time, hot water is supplied to the bathtub 20 using the cooling waste heat. That is, the high-pressure and high-temperature refrigerant gas from the compressor 1 passes through the four-way valve 2, the second on-off valve 15b which is in an open state, and radiates heat in the hot water supply heat exchanger 9 to supply hot water to the bathtub 20, and the refrigerant is condensed. It liquefies, passes through the check valve 11 and the open first on-off valves 13b and 13a, is depressurized by the cooling throttle device 6, enters the indoor heat exchanger 4, evaporates, and cools the room.
The gasified refrigerant is sucked into the compressor 1 through the fourth on-off valve 17b which is in an open state. At this time, all on-off valves other than those mentioned above are closed.

That is, the high-temperature, high-pressure gas from the compressor 1 passes through the four-way valve 2 and the second on-off valve 15a, which is in an open state, to radiate heat in the indoor heat exchanger 4 and heat the room, and the liquefied refrigerant passes through the check valve 8. The pressure is reduced by the waste heat recovery throttling device 10 through the first on-off valves 13a and 13b in the open state, and the residual water heat in the bathtub 20 is absorbed by the hot water supply heat exchanger 9, and becomes refrigerant gas, which is in the open state. Compressor 1 via on-off valve 17a
is inhaled. At this time, all on-off valves other than those mentioned above are closed.

In this case, the high-temperature, high-pressure gas from the compressor 1 passes through the four-way valve 2, one of which is open, and the second on-off valve. 15b and enters the hot water supply heat exchanger 9 to supply hot water to the bathtub 20.
1. It reaches the third on-off valve 12 via the first on-off valve 13b which is in an open state. The other is the second on-off valve 1 in the open state.
5a, the refrigerant enters the indoor heat exchanger 4 to heat the room, passes through the check valve 8 and the first on-off valve 13a in the open state, and then joins with the refrigerant from the indoor heat exchanger 4 to cool the third refrigerant. The refrigerant passes through an on-off valve 12, is depressurized by a heating throttle device 5, enters an outdoor heat exchanger 3, absorbs heat from the outside air, is gasified, and is sucked into the compressor 1 again via a four-way valve 2. At this time, the fourth on-off valve 17
a and 17b are in a closed state.
