Present work reports a detailed theoretical and experimental performance analysis of vapor compression refrigeration system (VCRS) using alternative refrigerants to find out the substitute of R22. First, a theoretical investigation is done using R134a, R410A R407C, R438A as the potential drop-in refrigerants for the same setup and compressor displacement volume using a thermodynamic model developed in Engineering Equation Solver (EES) software. The results of this analysis indicate that R438A is a better substitute to R22. Then a similar analysis is done to compare the performance of R22 and R438A for the same cooling capacity and input conditions but different setup and compressor displacement volume. The results indicate that R22 results in a better efficiency. In the end, experimental comparison of R22 and R438A is done on the same experimental set up designed for R22 and the results of first theoretical analysis are verified.
