  • Subway hybrid-energy multifunctional-end-integrated heat pump system and method
    Patent number: 11898779
    Abstract: A subway hybrid-energy multifunctional-end-integrated heat pump system includes energy and user ends and hot water tank. A first energy end includes a capillary-tube front-end heat exchanger and a subway capillary heat pump unit. A second energy end includes a solar panel. A third energy end includes an air-cooled heat pump unit. The user end includes air conditioner, hot water supply, underfloor heating, and radiator heating ends. The first, second and third energy ends connect to the hot water tank. A water outlet is connected to the air conditioner, hot water supply, underfloor heating, and radiator heating ends. Water outlets of the air conditioner, underfloor heating, and radiator heating ends are respectively connected to the first, second and third energy end through a return pipe.
