The case study presents results from a 1 year test period from a transcritical booster system installed in the Danish supermarket chain, Fakta. The chain owned by Coop Denmark has experienced significant savings in their energy consumption with their second generation transcritical booster system. It has now been documented that you can save energy with a transcritical booster system with gas by pass. Measurements indicate up to 10% energy savings compared to conventional HFC – systems. The results also show a technology improvement since 2007 where the first generation transcritical system was installed.
