This work proposes a novel transparent solar cooker design, and its performance is evaluated using a set of experiments. The cooker is fabricated from transparent and non-transparent, and lightweight material. The study was conducted at the Renewable energy laboratory in India (MNNIT Prayagraj). For thermal performance assessment of Box-type standard solar cooker with an inclined cover (BTSCIC) is compared with a box-type standard solar cooker (BSSC). The area, heat input, and thermal efficiency have all increased significantly. The total absorbing area increases by 32%, total solar radiation by 189%, absorber plate temperature by 19.8%, inner air temperature by 16.5%, pot water temperature by 17.1%, and inner wall average temperature by 58%, as compared to box-type Standard Solar Cooker. The average exergy was 4.2% (BTSCIC) and 2.61% (BSSC), respectively. The cost payback period of BTSCIC was 2.22 years and BSSC 1.5 years.
本工作提出了一种新颖的透明太阳能炊具设计，并通过一组实验对其性能进行了评估。炊具由透明和不透明、轻质材料制成。该研究在印度可再生能源实验室（MNNIT Prayagraj）进行。为了评估箱式标准太阳能炊具（BSSC）的热性能，将带倾斜盖的箱式标准太阳能炊具（BTSCIC）与 BSSC 进行了比较。与 BSSC 相比，BTSCIC 的面积、热输入和热效率都有显著提高。总吸收面积增加了 32%，总太阳辐射增加了 189%，吸收板温度增加了 19.8%，内部空气温度增加了 16.5%，锅水温度增加了 17.1%，内壁平均温度增加了 58%。BTSCIC 和 BSSC 的平均火用分别为 4.2%和 2.61%。BTSCIC 的成本回收期为 2.22 年，BSSC 为 1.5 年。
