| Abstract: | In this study, the energy performance of eco-friendly refrigerants (R152a and R600a) was investigated theoretically as alternative to R134a in refrigeration system. The results showed that the vapour pressure and specific volume of R152a are very close to those of R134a. R152a emerged as the most energy efficient with average Power Per Ton of Refrigeration (PPTR) of 10.6% less than that of R134a. R152a also exhibited higher Volumetric Refrigerating Capacity (VRC) and Coefficient of Performance (COP) than both R600a and R134a. The average COPs obtained for R152a and R600a were 13.4% higher and 5.4% lower than that of R134a, respectively. Generally, R152a performed better as R134a substitute in that it has the lowest PPTR, highest thermal conductivity, refrigerating effect, VRC and COP. |
