Abstract: Vapour compression refrigeration-based air conditioners are being used for comfort cooling in residences, offices and commercial buildings in many countries throughout the world. These systems consume substantial power and energy and produce harmful effect on environment by damaging ozone layer. This article presents an analytical evaluation of energy saving potential of an indirect evaporative cooler for summer months in Indian climates. Three climates likely to be suitable for indirect evaporative cooling, namely composite, hot and dry and moderate, have been selected for this purpose. The monthly average environmental data for three Indian cities namely Delhi, Jodhpur and Bangalore representing three different climates were used for this study. Summer month—May was selected for the study. It has been found that in order to produce same cooling effect under the same climatic conditions, the power needed by indirect evaporative cooler to be about 55% less than that needed by a conventional air conditioner. The performance of an indirect evaporative cooler in the climates, hot and dry and composite, has been found to be almost similar. Thus, substantial energy can be saved by using this alternative in summer months.
