The axiomatic effects of ozone layer depletion have caused additional damage in the last few decades. The accretion in greenhouse gases has transformed to take cardinal steps immediately. The concoct blend of 1,1,1,2 Tetrafluroethane (R134a) and 1,1, Difluroethane (R152) a was tested in a vapour compression refrigeration system as these are non-toxic, eco-friendly, non-flammable and non-corrosive. Experimental performance analysis of vapor compression refrigeration system using R134a and blends of R152a and R134a is done for different dimensions of expansion valves. Various parameters like coefficient of performance (COP), refrigerating effect and compressor work were analyzed. Refrigeration effect and compressor work of R134a was higher than R152a. COP value was reliable for 60/40 ratio of R152a and R134a and maximum COP was achieved with the blend of 90/10 ratio in the first expansive coil. These aberrant results could be overcome by amalgamation of R134a and R152a as the discharge temperature of R152a is effectively controlled by blending.
