Abstract

Photovoltaic Thermal (PVT) systems have garnered attention for their dual functionality of generating electricity and capturing heat. However, conventional PVT systems often employ bulky metallic pipes with forced fluid circulation, leading to higher initial costs, increased maintenance, and elevated energy consumption. To overcome these challenges, this research introduces a novel lightweight acrylic sheet insulator design utilizing natural water flow as the working fluid. The study explores parameters such as thermal efficiency, electrical efficiency and flow rate to assess system performance. A comprehensive mathematical model based on energy balance equations is developed to predict system behavior. The model demonstrates strong agreement with experimental data, affirming its accuracy. The results reveal a 1.95% improvement in electrical efficiency compared to traditional PV systems. This work provides a foundation for optimizing PVT systems through energy balance modeling and experimental validation, paving the way for more cost-effective and efficient designs.

光热混合系统中具有自然流动集成的轻质丙烯酸平板集热器的性能评价

光伏热（PVT）系统因其发电和集热的双重功能而备受关注。然而，传统的PVT系统通常使用笨重的金属管道，强制流体循环，导致初始成本较高，维护费用增加，能耗增加。为了克服这些挑战，本研究引入了一种新型的轻质亚克力板绝缘子设计，利用自然水流作为工作流体。该研究探讨了热效率、电效率和流量等参数来评估系统性能。建立了基于能量平衡方程的综合数学模型来预测系统行为。模型与实验数据吻合较好，验证了模型的准确性。结果显示，与传统光伏系统相比，该系统的电力效率提高了1.95%。这项工作为通过能量平衡建模和实验验证优化PVT系统提供了基础，为更具成本效益和效率的设计铺平了道路。

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.
