The present disclosure provides a "vapor injection heat pump". A heat pump includes a refrigerant circuit. The refrigerant circuit includes a compressor, a first region of a first heat exchanger, a first branch point, a first shut-off valve, a second shut-off valve, and a second heat exchanger. The compressor includes a low pressure inlet, a medium pressure inlet, and an outlet. The first heat exchanger is positioned immediately downstream of the outlet of the compressor. The first branch point is positioned immediately downstream of the first region of the first heat exchanger. The refrigerant circuit is divided into a first path and a second path at a first branch point. A first shut-off valve is positioned along the first path and positioned immediately downstream of the first branch point. A second shut-off valve is positioned along the second path and positioned immediately downstream of the first branch point. The second heat exchanger is downstream of the first heat exchanger.
本公开提供了“蒸气喷射热泵”。一种热泵包括制冷剂回路。制冷剂回路包括压缩机、第一热交换器的第一区域、第一分支点、第一截止阀、第二截止阀和第二热交换器。压缩机包括低压入口、中压入口和出口。第一热交换器定位成紧接在压缩机的出口的下游。第一分支点定位成紧接在第一热交换器的第一区域的下游。制冷剂回路在第一分支点处分成第一路径和第二路径。第一截止阀沿着第一路径定位并且定位成紧接在第一分支点的下游。第二截止阀沿着第二路径定位并且定位成紧接在第一分支点的下游。第二热交换器在第一热交换器的下游。
