Experimental Performance of a Direct Evaporative Cooler Operating in Kuala Lumpur

Abstract

The present work presents an experimental investigation on the performance of a direct evaporative cooler in hot and humid regions. The experimental study is based on weather data from Kuala Lumpur, Malaysia. The direct evaporative cooler consists of a cellulose pad with a surface area per unit volume ratio of 100 m2 /m3 . The performance of the evaporative cooler is evaluated using the output temperature, saturation efficiency, and cooling capacity. The output temperature of the air varies between 27.5°C and 29.4° C, while the cooling capacity is between 1.384 kW and 5.358 kW.
