This document summarizes a presentation given at the XV European Conference in Milano on the latest refrigeration and air conditioning technologies for high efficiency supermarkets. It discusses a waterloop solution using brushless DC compressors that can reduce refrigerant leakages by 70-85% and charges by over 70% compared to traditional systems. Simulation results show this approach can save 29% of energy and reduce total equivalent warming impact over a 10 year period by 55% compared to traditional supermarkets. The waterloop solution provides flexible and efficient operation of stand-alone display cabinets.
