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.

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.
