The aim of this paper is the numerical study of two new configurations of the Barra-Costantini system using building integrated semi-transparent PV technology. Each configuration is integrated into a room located in Ksar Chalala in Algeria. In the first new system, the glass of the conventional Barra-Costantini system is replaced by a PV glass panel. While in the second one, a single glass is placed in front of the PV glass panel. The thermal models of the systems are established by taking into consideration the solar gains by the calculation of the sunspot area on each one of the walls exposed to the direct solar radiation. By comparing the performance of the conventional Barra-Costantini system with that of the two proposed configurations, our results have shown that the use of the PV glass panel allows the system to produce simultaneously heat and electricity. The conventional Barra-Costantini system gives an internal air temperature of 22.9 °C, while systems with glazed semi-transparent PV and semi-transparent PV only produce temperatures of 22.6 °C and 21.5 °C, respectively. The maximum electrical efficiency of the PV glass panel is 15.6%, while that of the glazed PV glass panel is 13.1%.

本文的目的是使用建筑物集成的半透明光伏技术对Barra-Costantini系统的两个新配置进行数值研究。每种配置都集成到位于阿尔及利亚Ksar Chalala的房间中。在第一个新系统中，传统的Barra-Costantini系统的玻璃被PV玻璃面板取代。在第二个中，将单个玻璃放置在PV玻璃面板的前面。系统的热模型是通过计算暴露于直接太阳辐射的每一壁上的黑子面积并考虑到太阳增益而建立的。通过将传统的Barra-Costantini系统的性能与所提出的两种配置的性能进行比较，我们的结果表明，使用PV玻璃面板可使系统同时产生热量和电能。传统的Barra-Costantini系统的内部空气温度为22.9°C，而具有玻璃半透明PV和半透明PV的系统分别只能产生22.6°C和21.5°C的温度。光伏玻璃面板的最大电效率为15.6％，而釉面光伏玻璃面板的最大电效率为13.1％。
