Summary

Heat recovery from refrigeration systems is a commonly applied measure to increase energy efficiency in supermarkets, upgrading the heat otherwise rejected to the atmosphere in condensers. The aim of this work is to investigate the technical potential and economic outcome of heat recovery and heat export in three different supermarkets. Field measurement data from three supermarket refrigeration systems with heat recovery are collected and used as a basis for computer modelling and simulation. Energy costs are gathered from the supermarkets and the profitability of heat recovery and heat export are evaluated. The results show that the supermarkets could save up to 40 % in annual operational costs for refrigeration and heating if disconnecting from the district heating network and producing all the required heating in the store with the refrigeration system, and up to 48 % if maximising the produced heat and selling the surplus to a neighbouring building.
