The aim of this paper is to evaluate the exergetic performance of a residential air conditioner working with R22 and the new ternary mixture. R32, R125, R600a are the constituents of the new mixture in the ratio of 0.4:0.4:0.2 by mass and it is designated as RM20. The experimental tests are carried out and comparative exergy analysis has been done and presented. The collective exergetic performance of the plant working with R22 is better than that of the new mixture. The exergetic performances of the individual components are also evaluated. The compressor has larger exergy destruction followed by condenser, evaporator and expansion valve.
