Résumé

This study evaluates heat recovery from a refrigeration system in a supermarket where the heat is supplied both to the supermarket and to apartments in the same building. As the incentives of the supermarket and the property owner are not necessarily aligned, collaborative heat recovery requires an agreement beneficial for both parties. The objective of this work is to demonstrate, using techno-economic analysis, that cooperation between property owners and supermarkets for efficient heat recovery from refrigeration systems can be achievable and beneficial for both parties. Results from field measurements of the refrigeration system with heat recovery are compared with those of modelled floating condensing operation. Despite higher electricity costs from increased compressor energy use, the supermarket decreases its refrigeration system’s yearly operation costs by 36 %, with an investment payback time of 3.2 years, and the building gains 20 % savings in district heating costs.
