Experimental Performance Comparison of R134a and R600a Refrigerants in Vapour Compression Refrigeration System at Steady State Condition

N Austin;


This paper focuses on the performance comparison and analysis of refrigerants used in domestic compression refrigeration systems in the premises of steady state.R134a and R600a are the two refrigerants considered for comparison. Refrigerators used for domestic as well as household uses were chosen for conducting the experiments. The achieved results show that 50g of R600a produces the same output as produced by R134a.Based on the results, R600a performance compressor coefficient, charge amount and condenser evaporator were chosen for the analytical design. Out of the various outcomes, the variance result supported the view that R600a charge amount was the most notable parameter. At conditions which are optimal the charging amount necessary for R600a was found to be 60g which was 68% lesser than R134a.Other working parameters include heat transfer performance and capillary tube dimensions. Comparison and review results show that R600a performs better than R134a.
