Innovative system for heat recovery from used water in the building sector

Abstract This study presents a Computational Fluid Dynamics (CFD) Heat Transfer Analysis for an originally designed System for Heat Recovery from Used Water in the Building Sector. The research is focused on developing an energy efficient heat pipe heat exchanger which can recover an important quantity of heat from the residual energy form the used water from buildings. For the proposed paper we analyzed using Autodesk Simulation CFD Software the operation of the heat pipe heat exchanger system in different hypothesis for proving its energy efficiency. The proposed device has a lot of advantages as low cost of manufacturing, exploitation and maintenance and it is very easy to install and use.
