Abstract

The main challenge associated with solar panels is the need to reduce excessive heat and optimize efficiency to achieve stable conditions. Therefore, a combination of collector and cooling technologies, such as Photovoltaic Thermal (PVT) Technology, is needed to address this problem. This research used water-based rectangular channel to cool the PVT through the Ansys simulation method. A total of nine variations of mass flow rates, which ranged from 0.001 to 0.009 kg/s and six solar intensities between 500 W/m² and 1000 W/m² were used to achieve the optimal performance. An energetic analytical method with average Sustainability Index (SI) of 0.001–0.009 kg/s and 1.186 at 1000 W/m² intensity were incorporated. Furthermore, the maximum average Waste Exergy Rasio (WER) value of 0.854 at a 500 W/m² intensity was used to determine the flow rate. The highest average Exergetic Ecological Index (EcEI) value recorded was −0.687 at a 1000 W/m² radiation intensity, while the highest average Improvement Potential (IP) value was 421.145 W. The results showed that the simulation serve as a valuable point of reference in the design and advancement of water-based rectangular channel within future PVT technology.

带矩形通道的光电热能的可持续性指数和文献计量学

太阳能电池板面临的主要挑战是需要减少过多热量并优化效率，以实现稳定的条件。因此，需要结合集热器和冷却技术，如光伏热技术（PVT）来解决这一问题。本研究通过 Ansys 仿真方法，使用水基矩形通道冷却 PVT。为了达到最佳性能，共使用了九种质量流量变化（从 0.001 到 0.009 kg/s）和六种太阳辐射强度（从 500 W/m2 到 1000 W/m2）。采用的能量分析方法的平均可持续性指数（SI）为 0.001-0.009 kg/s，1000 W/m2 强度时为 1.186。此外，在确定流量时，还使用了 500 W/m2 强度下的最大平均废物能耗（WER）值 0.854。在辐射强度为 1000 W/m2 时，记录到的最高平均能效生态指数 (EcEI) 值为 -0.687，而最高平均改善潜力 (IP) 值为 421.145 W。

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
