Abstract
This paper presents the results of a 24-month field monitoring of CO2 transcritical units designed to satisfy all the thermal needs of food retail stores, namely refrigeration, heating and cooling. The units, adopting state-of the art technologies, such as two phase ejectors and parallel compression, are developed within the H2020 project MultiPACK. The monitored supermarkets are located in Italy, in two different climatic areas, featuring different heating and cooling demands for indoor comfort, as well as diverse building type and display cabinets mix. Long lasting measurements allow for evaluation of energy and efficiency related KPIs, together with operational indicators. These figures are relevant for benchmarking with traditional solutions.
