Abstract
Meeting demand for electric power during peak periods in the summer is a major concern for most utilities in the fast-moving world. From the demand points of view on the grid and cost to the consumer, it would be quite wise to install, energy-efficient evaporative coolers rather than conventional air conditioners. Evaporative cooling has a great many advantages over other cooling processes. Due to the non-pollution creating environment, it is one of the healthiest ways to cool ones workplace or living place because of the fact that it uses clean fresh air and replaces the air many times an hour. Due to recirculation of air, smells and allergens are expelled. Based on a totally natural process of air cooled by water, it won’t dry out the air, or irritate human skin, throat or eyes. Doors can be left open allowing one to enjoy the summer. Moreover, evaporative cooling is also an inexpensive cooling option which enhances the lifestyle of people. However, evaporative cooling requires abundant water and is only efficient when the relative humidity is low. Padding media play a major part in cooling efficiency. This paper investigates the performance of Desert Cooler using six different pads in terms of cooling efficiency, water consumption and air velocity for a sustainable and economic application. In real practice, we use wood wool, khus, coconut coir fiber, ceramic materials tubes, stainless steel, galvanized metal sheets as pads in desert coolers and the paper focusses on the best of the pads used, quite suitable to the rural masses in operational and economic senses, on a wide range of comparisons. This investigation is sorted out to bring the performance indicator of the best suited pad out of different pads used globally.
