Recovery methods of waste heat energy and their applications

SUMMARY RECOVERY METHODS OF WASTE HEAT ENERGY AND THEIR APPLICATIONS Reşat SELBAŞ Keywords: Reküperatör, Re jeneratör, Thermal Wheel. In this study waste heat recovery methods have been examined and properties of equipments and figures have also been shown. Additionally heat recovery equipments have been compared with each other and their utility ranges have been given in charts. Thermal wheel is very important in low temperature application of waste heat recovery. Thermal wheel is composed of a porous disc having high thermal capacity. It saves energy by carrying the heat of cold or hot exhaust gases into cold or hot inlet air. In this study, a thermal wheel is added into air conditioning equipment. Thermal energy which is recovered was calculated. Cost of system and payback time were determined. So, a research was made about importance of heat recovery application of thermal wheel in general. viii
