Study of Modified Evaporative Desert Cooler For its Performance Optimization

Abstract: Evaporative cooling is a very common form of cooling buildings for thermal comfort, since it is relatively cheap and requires less energy than many other forms of cooling. However evaporative cooling requires an abundant water source as an evaporate, and is only efficient when the relative humidity is low, restricting its effective use to dry climates. Traditionally, evaporative cooler pads consist of excelsior (wood wool) inside containment net. Padding media plays a large part in cooling efficiency and water consumption. Our paper aims to review the recent developments of concerning evaporative cooling technologies that could provide sufficient cooling and comfort using a pad material inside mesh net in terms of cooling efficiency, water consumption and air velocity. The purpose of this paper is to make an evaporative desert cooler more efficient and maintenance free, by making wood wool pad slide. They are assembled in such a manner that it can slide through u-channel and the top portion is duct which can also be placed or removed easily.
