The photovoltaic thermal system is widely used in producing electricity and thermal from solar energy. This study focused on improving the performance of the solar air heater coupled with a finned photovoltaic system as an absorber plate. The compound parabolic concentrator was installed on the right and left sides of the solar panel to enhance the absorptivity of solar radiation. The V-shape fins were placed under the solar panel to reduce the temperature of the photovoltaic system. Ambient air entered the solar dryer by a fan, passed through the solar panel, flowed on the fins installed under the panel, and exited the solar dryer. Four experiments were performed using 0, 8, 16, and 24 fins. The ambient air temperature increased by the convective heat transfer through the panel and fin, and the surface temperature of the panel decreased. The hot outlet air was used as an air dryer. The thermal and electrical efficiencies, economic, and enviroeconomic of the Photovoltaic/thermal solar air dryer were investigated. The results showed that the CO2 mitigation of the system using 24, 16, and 8 fins improved by 35.1%, 22.8%, and 10.7%, respectively. Also, the electrical and thermal efficiencies of the photovoltaic/thermal solar air dryer using 24 fins were enhanced by 28.7% and 30.6%, compared to those without fins. Moreover, the power generation cost of the system using 24, 16, 8, and 0 fins was equal to 0.206, 0.196, 0.190, and 0.186 $/kWh, respectively.

复合抛物面聚光器翅片光伏/太阳能热风干燥机性能分析

光伏热力系统广泛用于从太阳能产生电力和热能。这项研究的重点是提高太阳能空气加热器与作为吸收板的翅片光伏系统相结合的性能。复合抛物面聚光器安装在太阳能电池板的左右两侧,以提高对太阳辐射的吸收率。V形鳍片放置在太阳能电池板下方,以降低光伏系统的温度。环境空气通过风扇进入太阳能干燥器,穿过太阳能电池板,在安装在面板下方的翅片上流动,然后离开太阳能干燥器。使用 0、8、16 和 24 个翅片进行了四个实验。通过面板和翅片的对流传热,环境空气温度升高,面板表面温度降低。热的出口空气用作空气干燥器。研究了光伏/热太阳能空气干燥器的热效率和电效率、经济性和环境经济性。结果表明,CO使用 24、16 和 8 个鳍片的系统的2缓解分别提高了 35.1%、22.8% 和 10.7%。此外,与没有翅片的干燥器相比,使用 24 个翅片的光伏/热太阳能空气干燥器的电效率和热效率分别提高了 28.7% 和 30.6%。此外,使用 24、16、8 和 0 个翅片的系统的发电成本分别等于 0.206、0.196、0.190 和 0.186 $/kWh。
