Energy efficient heat pipe heat exchanger for waste heat recovery in buildings

Abstract This study presents a Computational Fluid Dynamics (CFD) Heat Transfer Analysis for an originally designed Energy Efficient Heat Pipe Heat Exchanger for Waste Heat Recovery in Buildings. The research is focused on developing a heat pipe heat exchanger for domestic hot water and thermal agent preparation, preheating / heating the air from ventilation systems in buildings, using as a primary agent the return of the existing heating system. The proposed device has a lot of advantages as high efficiency for heat recovery, low cost of manufacturing, exploitation and maintenance and it is very easy to install and use.
