Abstract
A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a suction heat exchanger configured to add heat to working fluid prior to entering the compressor, so as to support the generation of superheat by the HVACR system. The superheat can be controlled to achieve desired levels, so as to support the separation of lubricant from working fluid of the HVACR system. The suction heat exchanger can heat the working fluid passing to the suction of the compressor by exchanging heat with working fluid sourced from between the lubricant separator and the condenser. The suction heat exchanger can further be used as a receiver for controlling the charge of working fluid circulating in the HVACR system.
