  • Publication number: 20230132393
    Abstract: An air source heat pump system includes at least one heat pump sub-system and at least one water tank. Each heat pump sub-system includes a refrigerant circulation path and a water supply circulation path. The refrigeration circulation path includes a compressor, a first heat exchanger, a first throttling device, and an evaporator that are sequentially connected to one another. The water supply circulation path includes a first supply pipe, a second supply pipe, a return pipe, and a waterway control valve. The first supply pipe and the second supply pipe are each communicated with an end of the first heat exchanger through the waterway control valve, and the return pipe is communicated with another end of the first heat exchanger. The return pipe is communicated with a water inlet of a corresponding water tank, and the second supply pipe is communicated with a water outlet of the corresponding water tank.
