Energy is an important unit for development. India is a developing country. Energy needs of various sectors has increased rapidly. In the present energy crisis scenario, many people think in terms of alternate energy sources and conservation methodologies. In the context of great uncertainty over future energy supplies, attention is being paid to conserve energy and use it as an alternate source.. Air conditioning units are designed to remove heat from interior spaces and reject it to the ambient air. While this heat is of low grade variety it still represents wasted energy. From an energy conservation point it would be desirable to reclaim this heat in a usable form. The best and most obvious form of heat recovery is for heating water. The main objective of this paper is experimental analysis of waste heat recovery system and utilization of the recovered heat as a source for generating hot water and thus saving electricity.
