Abstract

This study addresses the challenge of enhancing the spherical solar still (SPSS) performance by introducing a modified cords wick spherical solar still (CWSPSS) design. This design incorporates an additional absorber inside the SPSS with 25 wick cords attached to the upper absorber. The research also investigates the impact of installing square barriers at the base of the CWSPSS, both with and without mirrors. Furthermore, the impact of using a fan with an exterior condenser and nanoparticle-enhanced Phase Change Materials (PCM) was tested. The findings indicated that the production of the CWSPSS with baffles and reflectors increased by 165 % and 205 %, respectively. Additionally, the productivity of the CWSPSS with PCM and fan was enhanced by 243 % and 259 %, respectively. The highest efficiency achieved was 67.5 % for the CWSPSS with a fan. Ultimately, the findings demonstrate a significant 50 % reduction in production costs, positioning this innovative design as a promising solution for cost-effective freshwater production where there is plenty of sea water.

利用内置挡板、反射器和纳米颗粒相变材料提高球形太阳能电池的热性能

本研究通过引入改良的灯芯绳球形太阳能蒸发器（CWSPSS）设计，解决了提高球形太阳能蒸发器（SPSS）性能的难题。这种设计在 SPSS 内部增加了一个吸收器，并在吸收器上部连接了 25 根灯芯绳。研究还调查了在 CWSPSS 底部安装方形屏障的影响，包括安装和不安装反射镜。此外，还测试了使用带有外部冷凝器和纳米粒子增强相变材料（PCM）的风扇的影响。研究结果表明，带挡板和反射镜的 CWSPSS 产量分别提高了 165% 和 205%。此外，带有 PCM 和风扇的 CWSPSS 的生产率分别提高了 243 % 和 259 %。带风扇的 CWSPSS 的最高效率为 67.5%。最终，研究结果表明，生产成本大幅降低了 50%，这种创新设计有望成为在有大量海水的地方以经济高效的方式生产淡水的解决方案。
