Abstract

In today's essential
commodities, air conditioning system is one of the major energy consuming
elements. Nowadays evaporative cooling systems are mostly preferred as an
alternative to compressor-based air conditioned systems. It is reported that
evaporative cooling systems consume 60 - 70 % less energy compared to
compressor-based air conditioning systems. In this paper, performance analysis
of a mist evaporative cooler is carried out experimentally. The performance
parameters such as, drop in temperature, cooling capacity, saturation
efficiency, the coefficient of performance are evaluated with respect to
various ambient conditions and with a varied mass flow rate of air.
Experimental data used to develop an empirical correlation to predict the
temperature of cooled air by linear regression analysis. Predicted temperature
of cooled air temperature by empirical correlation is validated through
experimentation, and are good in agreement with experimental values.
