Effect of refrigerant on the exergy loss and performance in air conditioner using ejector as expansion device

This paper presents a numerical approach to determine the exergy loss in an air conditioner using (A/C) R22 and R290 as working fluid. The exergy loss should be minimized in order to increase the performance of the air conditioner. The present study investigates the A/C with cooling capacity of 2.4...
