This paper deals with the experimental work, which has been carried out in 1 ton of refrigeration window air conditioner working with ternary refrigerant mixture namely R152a/R290/R600 (by weight 80%/10%/10%). The properties of selected refrigerant mixtures were obtained from NIST REFPROP 7.0 for comparative analysis and refrigerant performance of proposed blends and of R22 for the given operating conditions. From the test results observation, The performance coefficient of M3 were found to be higher than that of R22 by 5.25% and the compressor power of M2, M3, M5, M1 were found to be lower by 5.22%, 5.22%, 1.74%, 0.87% respectively. Based on the experimentation and calculation, it is found that this new proposed mixture could be considered as potential replacement candidate for R22 in many applications and has shown better results as far as performance parameters are concerned and in turn theyare benign to the environment
