Therefore, there is no blowing noise and there is no problem of dust or the like because the cooling air is not blown into the room. Further, since the air blowing means (6) of the air heat exchanger (4) is not operated, there is no air blowing noise from the outdoor unit even if it is a screen door, and optimal cooling can be performed at bedtime.

Further, since the outer wall and roof that have been stored by the solar heat in the daytime are cooled to absorb the heat from the hot brine, the efficiency of the heat pump cycle for hot water supply can be improved and at the midnight.

The expansion valve 3 has a configuration in which the valve opening degree can be electrically adjusted, and the energization is controlled by the control device 20.

The air heat exchanger 4 receives air blown by a blower fan (blower means) 6 and evaporates the refrigerant decompressed by the expansion valve 3 by heat exchange with the atmosphere. The accumulator 7 separates the refrigerant evaporated in the air heat exchanger 4 into gas and liquid, stores the excess refrigerant in the cycle to adjust the amount of the refrigerant, and causes the compressor 1 to suck only the gas refrigerant.

Next, the hot water supply circuit W for hot water supply has a radiator 2 as a heating means for hot water supply, a hot water supply circulation pump 8 for circulating the hot water supply, and a hot water storage tank 9 for storing the hot water supply.

The hot-water supply water stored in the hot-water storage tank 9 is mainly used in the kitchen, bath, etc. after being mixed with cold water to adjust the temperature when the hot-water is discharged. In addition to the hot-water supply, for example, floor heating, indoor air conditioning, etc. It can also be used as a heat source. A throttle valve 10 adjusts the amount of tap water introduced so that the hot water in the hot water storage tank 9 maintains a predetermined temperature and a predetermined level range.
