Résumé

R471A is an A1 long term sustainable refrigerant with GWP<150 suitable for replacement of R404A and R134a in new installations for medium temperature application. This article presents an evaluation of R471A in a commercially avaibale R404A refrigerated open display cabinet. Performance evaluation of display cabinet showed lower energy consumption for R471A than R404A while maintaing similar product temperature. The 24-h energy consumption for system with R471A is 8% to 18% lower compared to R404A depending on the outdoor conditions. Life Cycle Climate Performance shows up to 60% lower total emisions for system with R471A. The results indicate that R471A is a promising replacement for R404A in medium temperature refrigeration application leading to significant reduction in both the direct and indirect emissions.
