The foremost objective of this paper is to perform energy and exergy analysis for different psychrometric processes in an air conditioning system.The different processes to be taken into consideration are- Sensible Heating, Sensible Cooling, Humidification, Heating and Humidification & Cooling and Humidification. Energy analysis performed keeps track of heat and work transfers but doesn’t indicate the source and magnitude of irreversible entropy creation. It helps us to direct the available resources efficiently and effectively. Exergy analysis was done both theoretically and by using REFPROP software. The exergy loss and efficiency are calculated at different ambient conditions i.e. at 22°C and 24°C with four different flow rates of air i.e.(0.8, 1.1, 1.3 and 1.6 m/s).The aid of exergy in evaluating various air conditioning parameters can be highly profitable, which results in various technical advantages like improvement in efficiency and reduction in emissions which leads to environmental advantages.
