In this research work, the conventional single slope still (CSS) with egg shells of breed Gallus gallus domesticus cascara as sensible heat storage (SHS) material are studied experimentally to enhance the yield. In this experimental investigation, the proposed single slope still (PSS) with SHS material was made in comparison with the CSS to evaluate the productivity of fresh water under the same ambient conditions. Comparatively, this PSS has higher thermal conductivity than the CSS. The yield obtained from the PSS is 2.46 L/m, while the yield from the CSS is 2.07 L/m. The average rate at which the rise of output fresh water obtained from the PSS is 18% more than the fresh water output obtained from the CSS. The daily energy efficiency of the PSS is 26.07%, and for the CSS, it is only 22.25%. The daily exergy efficiency of the PSS is 2.36%, and for the CSS, it is only 1.67%. Since using the egg shell will employ as organic waste management and modification in this still is economical, less initial, and maintenance cost.
在这项研究工作中，我们对传统的单坡式太阳能蒸馏器（CSS）进行了实验研究，使用鸡的鸡蛋壳作为显热储能（SHS）材料，以提高产量。在这项实验研究中，我们提出了一种新型的单坡式太阳能蒸馏器（PSS），并与 CSS 进行了比较，以在相同的环境条件下评估淡水的产量。相比之下，这种 PSS 的热导率比 CSS 更高。PSS 的产量为 2.46 L/m，而 CSS 的产量为 2.07 L/m。从 PSS 获得的输出新鲜水的平均增长率比从 CSS 获得的新鲜水产量高 18%。PSS 的日能量效率为 26.07%，而 CSS 仅为 22.25%。PSS 的日火用效率为 2.36%，而 CSS 仅为 1.67%。由于在这种蒸馏器中使用鸡蛋壳可以作为有机废物管理，并且这种改进在经济上、初始成本和维护成本上都是合理的。
