Abstract

This article scrutinizes the modeling of a Concentrated Photovoltaic-Thermal (CPVT) system incorporating a paraffin container. The CPVT setup integrates cylindrical and parabolic reflectors into the panel, utilizing RT-28HC as the paraffin and water as the working fluid implementing nano-powders. Fins are added to the absorber pipe within the paraffin container to improve energy storage, while a thermoelectric (TE) module beneath the silicon layer boosts electricity generation. Two CPVT setups are examined, exploring different fin configurations and reflectors. Visual representations like plots and contours illustrate the impact of key parameters, with model verification confirming alignment with prior research. Among the configurations tested, the combination of a parabolic reflector and seven fins leads to the highest heat storage within the paraffin layer. This configuration achieves an overall efficiency of 68.37 %. The addition of a parabolic reflector with seven fins results in the highest electrical power output. Within CPVT systems, this setup demonstrates exceptional performance, emphasizing the importance of meticulous component integration for superior results.

具有热电模块和纳米材料填充储罐的聚光太阳能光伏板的能量管理

本文详细介绍了一个集中的光伏热（CPVT）系统的建模，包括石蜡容器。CPVT装置将圆柱形和抛物面反射器集成到面板上，利用RT-28HC作为石蜡，水作为实现纳米粉末的工作流体。在石蜡容器内的吸收管上增加了翅片，以提高能量储存，而硅层下面的热电（TE）模块促进发电。研究了两种CPVT装置，探索了不同的鳍形和反射器。图和等高线等可视化表示说明了关键参数的影响，模型验证确认了与先前研究的一致性。在测试的结构中，一个抛物面反射镜和七个翅片的组合在石蜡层内的储热量最高。这种配置实现了68.37%的总效率。增加一个有七个鳍的抛物面反射器可以产生最高的电力输出。在CPVT系统中，这种设置展示了卓越的性能，强调了细致的组件集成对于卓越结果的重要性。

期刊介绍： Energy is a multidisciplinary, international journal that publishes research and analysis in the field of energy engineering. Our aim is to become a leading peer-reviewed platform and a trusted source of information for energy-related topics. The journal covers a range of areas including mechanical engineering, thermal sciences, and energy analysis. We are particularly interested in research on energy modelling, prediction, integrated energy systems, planning, and management. Additionally, we welcome papers on energy conservation, efficiency, biomass and bioenergy, renewable energy, electricity supply and demand, energy storage, buildings, and economic and policy issues. These topics should align with our broader multidisciplinary focus.
