Abstract: Heat exchangers are the important engineering systems with wide variety of applications including power plants, nuclear reactors, refrigeration and air-conditioning systems, heat recovery systems, chemical processing and food industries. Helical coil configuration is very effective for heat exchangers and chemical reactors because they can accommodate a large heat transfer area in a small space, with high heat transfer coefficients. This paper deals with the parametric analysis of the helical coiled heat exchanger with various correlations given by different researchers for specific conditions. The parametric analysis of these various correlations with specific data is presented in this paper.

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.
