Document Type and Number:
WIPO Patent Application WO/2024/051643
Kind Code:
A1
Abstract:
Provided in the present application is a heat pump system, comprising a compressor, a first heat exchanger, a second heat exchanger, a third heat exchanger and a valve device. The valve device comprises a first port, a second port, a third port, a fourth port, a fifth port and a sixth port, wherein the first port and the third port are connected to a suction port of the compressor; and the sixth port, the second port and the fourth port are respectively connected to a first port of the first heat exchanger, a first port of the second heat exchanger and a first port of the third heat exchanger. When the heat pump system is operated in a refrigeration mode, the first port of the first heat exchanger is in unidirectional communication with the suction port; and when the heat pump system is operated in a heating mode or a defrosting mode, the first port of the second heat exchanger is in unidirectional communication with the suction port. When the heat pump system is operated in a simultaneous refrigeration and heating mode, the first port of the third heat exchanger is in unidirectional communication with the suction port. The heat pump system of the present application can limit the unidirectional flow of a refrigerant in the heat exchanger, which is not in a refrigerant circulation loop, to the compressor without affecting the pressure drop in the refrigerant circulation loop.
