This experimental work focuses on the performance comparison of refrigerants used in domestic vapour compression refrigeration systems. The experimental work uses two refrigerants like hydro fluorocarbon refrigerant R134a(C2H2F4) and a hydrocarbon refrigerant as R600a(C4H10) for comparison. Refrigerators used for domestic as well as household uses were chosen for conducting the experiments. R134a is the most widely used refrigerant in domestic refrigerators. It must be phased out soon according to Kyoto protocol due to its high global warming potential of 1250. The achieved results show that 89g 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 89g which was 46.06% lesser than R134a.
