Abstract
An energy efficient heat pump for a heating, ventilation, and air conditioning (HVAC) system includes a working fluid circuit and a first conduit of the working fluid circuit, where the first conduit extends between a first heat exchanger and a second heat exchanger of the working fluid circuit. The energy efficient heat pump also includes a compressor disposed along the working fluid circuit, where the compressor is configured to direct a working fluid along the working fluid circuit, and the compressor includes a suction port and an injection port. The energy efficient heat pump further includes an injection conduit extending from the first conduit to the injection port of the compressor, where the injection conduit includes an expansion device, and the injection conduit is configured to direct a portion of the working fluid from the working fluid circuit, through the expansion device, and to the injection port.
