Simulation and Analysis of Experimental Photovoltaic Thermal (PVT) Solar Water Heater and Comparison of Turbulence Models

EasyChair Preprint 8795

Abstract

In order to clean the environment, by producing and assessing the solar water heater and by applying the analytical study of an experimental model by turbulence models with use of ANSYS in Islamic Azad University Central Tehran Branch during six years, we achieved considerable results that can be beneficial in its development. By increasing the temperature of solar panel surface, the thermal and electrical efficiency of solar panel will be increased and declined respectively and the solar cells will deteriorate in high temperature of solar plates by passing time. We can solve it by inserting water pool below the Photovoltaic-Thermal solar panel in this project. On the other hand, the decline of thermal efficiency can be compensated by inserting solar collector in the cycle. So the increase of electrical efficiency is more important and that is why we have chosen this issue as the aim of our research. By sunrise and increasing the heat flux from zero to 1250W/m^2, the interior and exterior levels of panel will be different to 20°C in average. Then voltage and amperage input (production) will be increased from 80% to 91% and from 71% to 84% respectively. The average water temperature from input to output will be also increased to 76°C.
