Abstract
A compressor driven by a variable-frequency drive (VFD) is provided to supplement operation of another compressor of a heating, ventilation, air conditioning, and refrigeration (HVACR) system, such as heat pump operations at low ambient temperatures. The VFD is controlled to provide efficient pressure ratios for each compressor of the HVACR system when the compressor driven by the VFD is used to supplement the other compressor. The compressor driven by the VFD can be included as a built-in compressor of the HVACR system or added subsequently as part of a booster package.
