摘要

本研究揭示了太阳能集热器（STC）的新颖设计及其在中温太阳能烹饪中的应用。这项工作的主要目的是证明所提议的集热器在实现分散能源应用的中间温度方面的实用性，从而提供多种可持续能源解决方案。通过基于热性能参数（TPP）的测试和评级，对用于烹饪的 STC 的光热性能进行了评估。通过测试烹饪用 STC 的两种配置，评估了设计引起的变化对性能的影响。使用热法估算了有效浓度比 (Ceff)。结果表明，第一种和第二种配置的 TPP 值和炊具光热比 (COR) 分别为 0.116 和 0.108（m2-°C）/W。此外，Ceff 值为 1.074。最佳配置的 LCSCM 值为 0.0323 美元/毫升。因此，本研究为开发和测试适用于多种应用的高效 STC 设计提供了有价值的见解，并为今后将其用于干燥、空气和水加热等其他应用提供了建议。

Enhancing clean energy access in decentralized communities through novel design of solar thermal collector: Experimental validation through intermediate temperature cooking

The present work reveals a solar thermal collector’s (STC) novel design and its use for intermediate-temperature solar cooking. The main aim of the work is to demonstrate the usefulness of the proposed collector in attaining intermediate temperatures for decentralized energy applications, providing multiple sustainable energy solutions. The opto-thermal performance of the STC for cooking is evaluated using thermal performance parameter (TPP) based testing and rating. The impact of design-induced change on the performance is assessed by testing two configurations of STC for cooking. The effective concentration ratio (C_eff) is estimated using the thermal method. The levelized cost of solar-cooked meals (LCSCM) demonstrates the techno-economic feasibility of the proposed collector for cooking.

The results showed that the value TPP, cooker opto-thermal ratio (COR) for the first and second configurations are 0.116 and 0.108 (m²·°C)/W, respectively. Also, the value of C_eff is 1.074. The LCSCM value for the best configuration is 0.0323 USD/Ml.

Therefore, the present work provides valuable insights into developing and testing an efficient design of STC for multiple applications and provides recommendations for its future use for several other applications, such as drying, air and water heating, and a few more.
