Investigation of The Effect of Gravity-Film Heat Exchanger on Hot Water Production
Abstract
The highest energy consumption sector in the worldwide varies according to different needs in residential areas. Energy losses occur in homes, workplaces, etc., due to water discharged into sewage systems. In this study, three different system designs were developed to reuse this energy: electric water heater for hot water production (M-1), electric water heater-GFHE for hot water production (M-2), and heat pump-GFHE for hot water production (M-3). Energy balance equations and empirical equations were used for the analysis of these systems. The results were compared in terms of energy consumption and COP value (Coefficient of Performance). The results showed that the design with the lowest energy consumption was the system that produced hot water with a heat pump-GFHE. Energy consumption decreased by approximately 88% to 90%, and the COP value increased by a factor of 8.9 to 11.24. The use of an electric water heater alone was seen as unsuitable due to its high energy consumption. It was determined that the use of GFHE for preheating water provided a significant improvement in system performance.
