Experimental Analysis & Performance Evaluation of a Split Air Conditioning System using R22, R407C and R410A

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 27 o C DBT, 19 o C WBT and 35 o C DBT, 24 o C 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).
