Summary

Current alternatives to R404A are either refrigerants with higher GWP from 1200 to 2000 or mildly flammable refrigerants with a charge limit of 1.2 kg. Therefore, non-flammable alternatives to R404A with lower GWP value need to be developed. In this study, a new non-flammable blend, named RTJU-Z (GWP of 794), has been proposed to directly replace R404A in cold storage system with only minor modifications. The flammability and thermodynamic performance of RTJU-Z is analysed. The thermodynamic performance of RTJU-Z is compared with the current alternatives to R404A (R407H, R442A, R449A and R452A) at different temperature. The results show that RTJU-Z is non-flammable and has a higher average value of COP than that of R404A by 9.43%. The average refrigeration capacity of RTJU-Z is slightly higher than that of R404A by 2.04%. RTJU-Z as a class A1 refrigerant can be directly used as an R404A alternative in cold storage system.
