Abstract

The high demand for power, industrialisation, transportation and global warming are all significant contributors to the rise in average earth temperature. Because of the greater ambient temperature, the total performance of the air conditioning system with an air-cooled condenser reduces dramatically. These limits pushed the researcher to look for other ways to improve the performance of air conditioners, such as increasing the heat transfer rate in the condenser using evaporative cooling pads. The influence of combining the condenser of a 1.5-tonne window air conditioner with evaporative cooling pads of varied thicknesses on air conditioner performance has been investigated in this study. The present work determines the optimal cooling pad thickness for the maximum Coefficient of Performance (COP) of air conditioner based on the experimental investigation. Experimental results have shown that a honeycomb cellulose cooling pad with a thickness of 2 inches would lower power usage of air conditioner by 15% and increase the COP by 45 %.
