Thermodynamic performance analysis of direct evaporative cooling system for increased heat and mass transfer area

Abstract

This paper demonstrates the thermodynamic performance analysis of direct evaporative cooling system by increasing sides of cooling media. In this paper, a different configuration of cooling media has been developed for determining the behaviour pattern of the direct evaporative cooling system based on performance characteristics using Aspen fibers media. The effect of inlet air temperature, humidity and mass flow rate of air has been discussed in detail by using the different configuration of cooling media. The result indicates that the saturation efficiency is approximately same for entire developed top flow and ordinary lateral flow configurations excluding triangle top flow configuration. The highest saturation efficiency were observed for triangle configuration 97% for case-I. Maximum saturation efficiency of the triangular configuration of an evaporative cooling system was found to be 97%, 88%, nil and 89% for case-I, case-II, case-III and case-IV respectively, over ordinary and other top flow DEC system.
