Abstract (en)
[origin: EP4246056A1] A refrigeration cycle apparatus includes a heat source unit including a compressor, a flow switching valve, a first heat exchanger, and an expansion valve, an air-conditioning unit including a second heat exchanger and configured to perform air-conditioning, and a hot water supply unit including a third heat exchanger and configured to supply hot water. The flow switching valve includes a first port connected to a discharge port of the compressor, a second port connected to the second heat exchanger, a third port connected to a suction port of the compressor, and a fourth port connected to the first heat exchanger. The flow switching valve is set to one of a first state in which the second port communicates with the third port, the third port communicates with the fourth port, and the first port does not communicate with any ports, a second state in which the first port communicates with the fourth port, and the second port communicates with the third port, and a third state in which the first port communicates with the second port, and the third port communicates with the fourth port.
