摘要

The F-Gas Regulation in the European Union (EU) has established a series of step-downs in EUHydrofluorocarbons (HFC) consumption. Due to that, new refrigeration systems using very-low GlobalWarming Potential refrigerants (GWP<150) like hydrofluoroolefins (HFOs) or transcritical CO_2 have beendeveloped. In this work, based on a real case study, we compare the performance, the life cycle cost andthe total emissions of several solutions in the commercial refrigeration applied to a supermarket with a totalcooling capacity of 190 kW. The comparison includes traditional HFC systems, low GWP systems andvery-low GWP HFO systems and other available solutions (transcritical CO_2, propane with glycol loop…).To perform a fair comparison, the ambient temperature and the energy cost for three major European citieswere taken into consideration in the calculations. While traditional HFCs are very efficient, HFOs cameout as the solution emitting the lowest total emissions over a 10-year lifetime.
