Abstract
An energy efficient heat pump for a heating, ventilation, and air conditioning (HVAC) system includes a compressor system configured to direct a working fluid along a working fluid circuit of the heat pump. The compressor system includes a first compressor configured to direct the working fluid along a first portion of the working fluid circuit having a first expansion device to operate the heat pump in a cooling mode and includes a second compressor configured to direct the working fluid along a second portion of the working fluid circuit having a second expansion device to operate the heat pump in a heating mode. The heat pump also includes a controller communicatively coupled to the first compressor and the second compressor, where the controller is configured to operate the first compressor and suspend operation of the second compressor in the cooling mode and to operate the second compressor and suspend operation of the first compressor in the heating mode.
