Résumé

Current alternatives to R404A are either refrigerants with higher global warming potentials (GWP) from 1200 to 2000 or mildly flammable refrigerants with a charge limit of 1.2 kg. Therefore, nonflammable alternatives to R404A with lower GWP values need to be developed. In this study, a new non-flammable refrigerant blend, named RTJU-Z (GWP of 794), has been proposed to directly replace R404A in a cold storage system with no modification. The flammability and thermodynamic performance of RTJU-Z were studied experimentally. The results show that RTJU-Z couldn't be ignited successfully and had a higher coefficient of performance (COP) value than that of R404A by 2.15%-5.71% at different cold storage temperatures. The optimal charge of RTJU-Z for the experimental system was 11.76% lower than that of R404A. The refrigeration capacity of RTJU-Z was about the same as that of R404A at the cold storage temperature from -20 °C to 10 °C. It is concluded that RTJU-Z can be directly used as a non-flammable alternative to R404A in a cold storage system with no modification.
