Claims

[Scope of utility model registration request]

The compressor 1, the four-way switching valve 2, the indoor heat exchanger 3, the liquid receiver 6, and the outdoor heat exchanger 9 are connected in series in order to constitute a main refrigerant circulation circuit Z, and the main refrigerant circulation circuit 2 is connected with the refrigerant. A hot water storage tank unit Y is equipped with a hot water storage tank 13 and a hot water supply heat exchanger 14 in a heat pump air-conditioning system that allows water to flow reversibly.
At the same time, the discharge pipe 21 of the compressor 1 and the refrigerant inlet side of the hot water heat exchanger 14 are kept fully open when not energized, and the valve opening degree can be changed from fully open to fully closed according to changes in the energized voltage. Refrigerant pipe 1 with interposed electromagnetic control valve 2-2 to be controlled
9, the refrigerant outlet side of the hot water supply heat exchanger 14 and the liquid receiver 6 are connected by a refrigerant pipe 20, and the electromagnetic control valve 22 is connected to the difference between the room temperature and a predetermined set temperature. the electromagnetic control so that the high pressure falls within the upper and lower limits of the set price during simultaneous heating and hot water storage operation according to a signal from the high pressure detector 24 whose set value of the high pressure is made variable accordingly;
A heat pump type air-conditioning/heating/water supply device characterized in that a control device 23 for controlling the opening degree of a valve 22 is attached.
