Abstract

This paper presents development and testing of a regenerative evaporative cooler. A conventional direct evaporative cooler has been modified by adding a water to air, heat exchanger in the path of outgoing air stream. The heat exchanger cools the air further by using cooled water available in the collecting tank Experiments have been conducted to study the performance of the regenerative evaporative cooler. It has been found that the efficiency and COP of regenerative system increases by 20 - 25%. The regener ative cooler having higher cooling capacity may be advantageous as it may attract more people for maximum utilization of this low energy consuming device leading to energy conservation in residential and commercial buildings
