| Summary: | 碩士 === 淡江大學 === 化學工程與材料工程學系碩士班 === 96 === The new solar hybrid photovoltaic/thermal (PV/T) system with multi-pass rectangular flow ducts is designed to improve the overall efficiency of thermal heat-transfer efficiency and PV cell efficiency. The theoretical formulations of the solar hybrid PV/T system are developed by making the energy balance and the resultant equations are solved by the fourth-order Runge–Kutta method. The factors affecting the device performance are the numbers of flow ducts, air mass flow rate, inlet air temperature and incident solar radiation. The theoretical results indicate that the heat transfer efficiency of solar air heater and solar hybrid PV/T systems increases with increasing the numbers of the rectangular flow ducts and air mass flow rate but decreasing with the incident solar radiation and inlet air temperature. The experimental apparatus of flat-plate solar air heaters and solar hybrid PV/T systems are also set up to confirm the accuracy of the theoretical predictions. The comparison between the theoretical predictions and experimental results shows that the good agreement is achieved in the present study.
