The main issues facing the supermarket refrigerationindustry are the phaseout of ozone-depleting refrigerants andthe improvement of refrigeration waste heat recovery. Thesystem presented in this paper involves secondary fluid loopson both condensing and refrigerating sides, with water-to-airheat recovery heat pumps. This improved concept has demonstratedits ability to reduce by at least 82% the quantity ofprimary refrigerant required. It has also a considerablepotential to reduce combined refrigeration and HVAC energyuse in stores located in northern climates compared tomultiplex refrigeration systems with more conventional heatrecovery approaches.
