A CASE STUDY ON ENERGY SAVINGS IN AIR CONDITIONING SYSTEM BY HEAT RECOVERY USING HEAT PIPE HEAT EXCHANGER

Abstract

In air conditioning facilities with high outside ai r requirements such as cleanroom air conditioning sconsiderable energy savings is possible by heat recovery using heat pip e heat exchanger (HPHX).The literature review indic ated that the annual energy saving analysis of air conditioning system w ith HPHX for Indian climatic conditions has not bee n 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 o f annual energy savings with number of rows of HPHX for Pune weather conditions. The application of heat pipe heat exchanger for en ergy savings in air conditioning system is strongly recommended.
