Optimizing The Operating Parameters In Waste Heat Recovery System

摘要

Global warming and continuous increase in population leads to the increase in energy demand in particular for heating ventilation and air condition systems. The energy requirement will increase 20% to 200% according to the countries in the year of 2020 for 1℃ cooling, increase in demand force the investigators to concentrate on waste heat recovery system. This investigation focused on to improve the effectiveness of waste heat recovery system using heat pipes charged with nanofluids. The following factors are considered for investigation filling ratio (A), concentration of graphine nano particle in working fluid (B), mass flow rate of air (C), humidity (D) and inlet temperature of air (E). The experimental results were analysed using Response Surface Method.
