An Experimental Analysis of Direct Evaporative Cooler by Varying Materials of Cooling Pad

This research aims to examine the performance of the direct evaporative cooler, by using the cooling pads of different materials. The efficiency of direct evaporative cooler mostly depends on the cooling pad and hence, the material used in the cooling pad plays a very vital role. Here, the performance of direct evaporative cooler is analyzed by using cooling pads of four different materials such as cellulose paper pad, wood fibers, wood wool (Aspen) and coconut fibres. Apart from these four types of cooling pads, also the performance of direct evaporative cooler is analyzed by using three different types of cooling pads simultaneously on three sides of the cooler, which mainly includes cellulose paper pad, coconut fibre pad and wood wool (Aspen) pad. Two most important terms considered in this analysis are temperatute and humidity. The readings of these two terms are taken for each type of cooling pad and also, the further calculations are done based on these readings. Comparison of results for various types of cooling pad is also done. The paper rounds off with conclusions and an agenda for future research in this area.
