냉매 회로의 열 펌프 모드에서 작동 가능한 압축기는 냉매가 압축되는 압축 공간을 포함한다. 압축 공간은 배출 포트와 분사 포트를 포함한다. 배출 챔버는 상기 배출 포트에 의해 상기 압축 공간에 유체적으로 연결된다. 분사 챔버는 상기 분사 포트에 의해 상기 압축 공간에 유체적으로 연결된다. 배출 재순환 경로는 상기 배출 챔버와 상기 분사 챔버 사이에 유체 연통을 선택적으로 제공한다. A compressor operable in a heat pump mode of a refrigerant circuit includes a compression space in which a refrigerant is compressed. The compression space includes a discharge port and an injection port. A discharge chamber is fluidly coupled to the compression space by the discharge port. An injection chamber is fluidly coupled to the compression space by the injection port. A discharge recirculation pathway selectively provides fluid communication between the discharge chamber and the injection chamber. An injection of the recirculated refrigerant into the compression space through the injection port results in an increase in pressure, and hence temperature, of the refrigerant when discharged to the discharge chamber. The increased temperature of the discharged refrigerant increases a heating capacity of a condenser of the associated refrigerant circuit.
