Summary

Current demands of the cooling sector are focused on using refrigerants with a low Global Warming Potential (GWP) in vapour compression installations. The main objectives of this paperwork arise from these needs, in which eco-friendly alternative refrigerants with a GWP under 150 are proposed and studied in an R-449A commercial refrigeration system. New refrigerant mixtures are searched from the binary and ternary combination of pure refrigerants. The best refrigerant with safety classification A1, A2L, and A2/A3, for both medium temperature (MT) and low temperature (LT) systems is obtained from this search. After their determination, the supermarket’s operation is simulated with these refrigerants. Finally, an environmental assessment is performed. The highest energy efficiency is obtained with the R-152a/R-1243zf mixture for the MT system and the R-290/R-1270 mixture for the LT system. However, the highest reduction of GHG emissions is achieved by R-290, with a reduction of 73.09% with respect to the baseline system.
