Demonstration of advanced integrated HVAC&R systems in a Loblaws supermarket in Canada.

Author(s) : GIGUÈRE D., PAJANI G., HOSATTE S.

Summary

A demonstration project of innovative refrigeration system technologies has been underway in a Loblaws supermarket in Canada with the technical support of the CANMET Energy Technology Centre-Varennes (CETC-Varennes) from Natural Resources Canada. The technology implementation allows reduction of greenhouse gas emissions by approximately 75% and energy consumption by approximately 25% compared to a typical supermarket. The principal innovation at this 10,000 square-meter Loblaws is the installation of a secondary-loop refrigeration system integrated with the building's heating and ventilation system. The objective of the secondary-loop system is threefold: to reduce refrigerant charge and therefore leaks, to facilitate heat recovery, and obtain a better quality of cold to limit food spoilage. For instance, heat recovery provides for all heating and hot water demand allows the elimination of the furnace. The project detail and the performance analysis is presented.
