Abstract
A heat-pump system includes a compressor, an outdoor heating exchanger, an indoor heat exchanger, an expansion device, and a supplemental heater. The outdoor heat exchanger is in fluid communication with the compressor. The indoor heat exchanger is in fluid communication with the compressor. The expansion device is in fluid communication with the indoor and outdoor heat exchangers. The supplemental heater includes a heat source and a working-fluid conduit. The heat source is in a heat-transfer relationship with the working-fluid conduit such that the heat source is configured to heat the working-fluid conduit. The working-fluid conduit is disposed fluidly between the expansion device and the indoor heat exchanger.
