The present disclosure provides a "vapor injection heat pump". A heat pump includes a refrigerant circuit. The refrigerant circuit may include a compressor, a first region of a first heat exchanger, a second heat exchanger, and a bypass branch. The compressor includes a low pressure inlet, a medium pressure inlet, and an outlet. The first heat exchanger is positioned downstream of the outlet of the compressor. The second heat exchanger is positioned downstream of the first heat exchanger. The bypass branch includes an inlet and an outlet. The inlet of the bypass branch is positioned downstream of the outlet of the compressor and upstream of the first region of the first heat exchanger. The outlet of the bypass branch is positioned upstream of the second 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。制冷剂回路可以包括压缩机、第一热交换器的第一区域、第二热交换器和旁路分支。压缩机包括低压入口、中压入口和出口。第一热交换器定位在压缩机的出口的下游。第二热交换器定位在第一热交换器的下游。旁路分支包括入口和出口。旁路分支的入口定位在压缩机的出口的下游和第一热交换器的第一区域的上游。旁路分支的出口定位在第二热交换器的上游。
