Claims

[Scope of utility model registration request]

Piping connects an outdoor unit that has a refrigerant compressor and a heat exchanger on the heat source side that serve as a source of air conditioning and heating, and an indoor unit that has a heat exchanger on the user side that blows cold and hot air into the room based on the refrigerant supplied from the outdoor unit. In the air conditioning/heating water supply system in which a hot water supply kit having a hot water heat exchanger is added to the air conditioning/heating system comprising: a first solenoid valve provided to bypass the first solenoid valve; a branch pipe of gas refrigerant piping connecting the outdoor unit and the indoor unit; A second check valve and a second solenoid valve connected in series between the refrigerant inlet of the hot water heat exchanger, and a high pressure liquid refrigerant pipe on the indoor unit side and the refrigerant outlet of the hot water heat exchanger. a third check valve connected in series between the second check valve and the second solenoid valve; 4, a refrigerant amount adjusting cylinder connected in series between the refrigerant outlet of the hot water supply heat exchanger and the refrigerant inlet side of the compressor of the outdoor unit, and a third electromagnetic valve; A liquid reservoir is provided between the refrigerant adjustment capillary and the third solenoid valve, and the first solenoid valve is used for cooling, the second solenoid valve is used for hot water supply, and the third solenoid valve is used for cooling and hot water supply. The solenoid valve is controlled to open during cooling, heating, hot water supply, and overheating operation during cooling and hot water supply, and close at other times.
