Abstract

In recent years, extensive research has focused on leveraging solar energy as a primary contributor to renewable energy applications, emphasizing the optimization of energy systems tailored to regional demands and resources. This study proposes a solar energy-based heating system and evaluates the impacts of various auxiliary heat sources in Zhengzhou, China (latitude 34.75°). The research evaluates the influence of different auxiliary heat sources on system performance and investigates the optimal tilt and azimuth angles for solar collectors to maximize thermal efficiency. Results indicate that integrating a heat pump as an auxiliary heat source minimizes energy consumption and enhances economic viability. Notably, the optimal tilt angle of the solar collector deviates by approximately 5° from the geographical latitude. Moreover, analysis reveal consistent trends in azimuth and installation angles, particularly when the optimal azimuth angle is 0°, thereby impacting solar collector efficiency.

带有不同辅助热源的太阳能供热系统的数值研究

近年来，大量研究集中于利用太阳能作为可再生能源应用的主要贡献者，强调根据地区需求和资源优化能源系统。本研究在中国郑州（纬度 34.75°）提出了基于太阳能的供热系统，并评估了各种辅助热源的影响。研究评估了不同辅助热源对系统性能的影响，并研究了太阳能集热器的最佳倾斜角和方位角，以最大限度地提高热效率。结果表明，将热泵作为辅助热源可最大限度地降低能耗，提高经济可行性。值得注意的是，太阳能集热器的最佳倾斜角度与地理纬度的偏差约为 5°。此外，分析还揭示了方位角和安装角的一致趋势，尤其是当最佳方位角为 0°时，从而影响了太阳能集热器的效率。

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.
