In this experimental work, the phosphate bed was used to augment a Conventional Solar Still (CSS) yield. The CSS was manufactured and operated under the climatic condition of El Oued, Algeria. To evaluate the phosphate as energy storage materials in the CSS, a 10 mm thick phosphate bed was made at the distiller's bottom. The phosphate bed is considered energy storage materials with good thermal conductivity. This material acts as an energy source in the basin after sunset and at times when the intensity of solar radiation decreases. The investigational outcome confirmed that the CSS's daily output contains a phosphate bed is higher than CSS production. Daily production with phosphate bed is equal to 3.55 kg/m², while its value is recorded at 3.04 kg/m² for the CSS. The use of phosphate bed increases daily production by 16.8% compared to the CSS. Besides, the daily energy efficiency is 31% for the CSS with phosphate bed as storage materials and 24.6% for the CSS.

磷酸盐床作为储能材料，用于提高传统太阳能蒸馏器的生产力

在这项实验工作中，磷酸盐床用于增加传统太阳能蒸馏器 (CSS) 的产量。CSS 是在阿尔及利亚 El Oued 的气候条件下制造和运行的。为了评估磷酸盐作为 CSS 中的储能材料，在蒸馏器底部制作了 10 毫米厚的磷酸盐床。磷酸盐床被认为是具有良好导热性的储能材料。这种材料在日落后和太阳辐射强度降低时充当盆地中的能源。调查结果证实，CSS 的日产量包含磷酸盐床高于 CSS 产量。磷酸盐床的日产量等于 3.55 kg/m ²，而其值记录为 3.04 kg/m ²对于 CSS。与 CSS 相比，磷酸盐床的使用使日产量增加了 16.8%。此外，以磷酸盐床为储存材料的 CSS 的日能源效率为 31%，CSS 为 24.6%。
