Incorporating HVAC into a grocery store's CO2 (R744) refrigeration system introduces parallel compression to stabilize medium-temperature (MT) compressor demand during high ambient temperatures. This finding comes from a case study conducted in Montreal by the Canadian-based OEM EVAPCO LMP.

The details of the integrated system's installation and operation, which also featured heat and gray water reclaim, were presented at the FMI- The Food Industry Association Energy and Store Development Conference. The presentation was given by Francois Aucoin, Director of Engineering at EVAPCO LMP, and Nicholas Torres, Commercial Refrigeration Sales Manager at EVAPCO, Inc.
