The main objective of the Paper is to present the performance analysis of a split air conditioning system of capacity 1.5tonnes using three refrigerants viz., R22, R407C(azeotriopic mixture of R32/R125/R134a, 23%/25%/52% by weight) and R410A(azeotropic mixture of R32/R125, 50%/50% by weight). The experimental test was conducted at standard ISO 5151 by maintain indoor & outdoor air temperatures at 27oC DBT, 19oC WBT and 35oC DBT, 24oC WBT respectively in an Air conditioning test room. The performance of each refrigerant has been found individually and the results were used to evaluate and compare the following performance criteria: Cooling capacity, Energy Efficiency Ratio and Co-efficient of performance (COP).
