Abstract
Despite the various advantages solar photovoltaic thermal (PVT) technology offers, it also has a notable downside. The PV module, a part of the PVT technology, is prone to heat gain due to solar exposure, which decreases its overall efficiency. Implementing an efficient cooling mechanism is essential in maintaining the PVT collector’s performance by regulating its temperature. A reversed circular flow jet impingement (RCFJI) method, designed to regulate the temperature of a PVT solar collector, is presented in this study. Energy and exergy analysis of the RCFJI was carried out through CFD simulation and indoor experiment with solar irradiance (I), = 700 W/m2 and 900 W/m2, while the mass flow rate (ṁ) varies from = 0.01 kg/s to 0.14 kg/s. The results indicate that the highest photovoltaic efficiency obtained by the CFD simulation and indoor experiment was 11.09 % and 10.91 %, while the highest thermal efficiency was 63.20 % and 61.34 %. Results for exergy efficiency showed that the CFD simulation and indoor experiment achieved a maximum efficiency of 48.34 W and 47.27 W, subsequently, with the highest thermal exergy of 9.91 W and 9.67 W. Nevertheless, the average percentage accuracy between the two methods demonstrated a notable level of consistency, surpassing 90 % accuracy, indicating a high agreement level between the two results obtained.
期刊介绍：
Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
