Abstract : The paper analyses the comparative performance of vapour compression refrigeration of environmental friendly alternatives for the commonly used refrigerants - R22 as well as R12 and R409A. The compared refrigerants are R438A, R407C, R410A and R454C as R22 replacements. The alternatives for R12 and R409A examined are R513a, R134a and R1234yf. The performances of refrigerants are tested in two refrigeration cycles - single stage vapour compression cycle and single stage vapour compression cycle with heat exchanger. The results indicated that among the R22 alternatives, up to condensation temperature of 20°C R454c has the highest coefficient of performance (COP) and above condensation temperature of 30°C R407c has the highest COP. Among R12 and R409 replacements R134a provides the highest COP for all practical values of condensation temperature.
