Tushar S. Jadhav, Mandar M. Lele

Abstract: In air conditioning facilities with high outside air requirements such as cleanroom air conditioning systems, considerable energy savings is possible by heat recovery using heat pipe heat exchanger (HPHX).The literature review indicated that the annual energy saving analysis of air conditioning system with HPHX for Indian climatic conditions has not been performed. The paper investigates the possible energy savings using HPHX for heat recovery in air conditioning system for a process air conditioning facility in Pune city, India. The impact of number of rows of HPHX and variations in the operating air conditions on the savings in cooling coil capacity is presented in this paper. The paper also reveals the comparative analysis of annual energy savings with number of rows of HPHX for Pune weather conditions. The application of heat pipe heat exchanger for energy savings in air conditioning system is strongly recommended.
