Energy and Exergy Analysis of Direct Evaporative Cooling System

ABSTRACT In this paper energy and exergy analysis of direct evaporative cooling system is presented. In this study ambient temperature, saturation specific humidity of the process and pressure at the end of the process is considered as the dead state. Variations in wet-bulb Saturation Effctiveness, change in thermal exergy, change in chemical exergy, total inlet exergy, total outlet exergy and exergy efficiency is analysed for pads of different thickness with constant face velocity. It is observed that for a give thickness of pads exergy efficiency does not change as wet bulb saturation efficiency changes
