Title:
AIR-SOURCE HEAT PUMP SYSTEM AND AIR-SOURCE HEAT PUMP CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/035511
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are an air-source heat pump system and an air-source heat pump control method. The air-source heat pump system comprises an electronic control module, a heat pump module and a bypass module. The heat pump module comprises a circulation pipeline, and a compressor, a four-way valve, a first heat exchanger, a refrigerant heat dissipation apparatus, a first expansion valve and a second heat exchanger, which are sequentially arranged on the circulation pipeline, wherein the first heat exchanger is used for performing heat exchange with water, and the refrigerant heat dissipation apparatus is thermally connected to the electronic control module. The bypass module comprises a bypass pipeline and a control valve, wherein a first end of the bypass pipeline is connected to the circulation pipeline between the first heat exchanger and the refrigerant heat dissipation apparatus, a second end of the bypass pipeline is connected to the circulation pipeline between the refrigerant heat dissipation apparatus and the first expansion valve, and the control valve is provided on the bypass pipeline, so as to selectively connect or cut off the bypass pipeline when the air-source heat pump system is in a heating mode.
