Abstract The impact of salty water medium and condenser type on the performance of single slope solar still is experimentally performed. Two solar still types are examined; conventional solar still with glass condenser (CSS) and solar still with plated finned heat sink condenser (MSS). The study is investigated for three saline water mediums in the still basin; pure saline water, sand saturated with saline water and steel wire meshes submerged inside the saline water. These stills are investigated in case of still only or still incorporated with parabolic trough collector (PTC) in hot and cold climate conditions of upper Egypt. Findings show that utilizing wire mesh, sand and heat sink condenser (HSC) raises the still freshwater yield and efficiency. The maximum freshwater yield rising in summer is 67%, 7.3% and 6% due to using PTC, HSC, and sand, respectively compared to CSS. The efficiency of all still systems in summer is found greater than winter. Moreover, utilizing HSC raises the still efficiency by 11.6% in summer and 8% in winter compared to CSS. MSS achieves the greatest efficiency of 41.95% in summer and 31.96% in winter while MSS+sand+PTC accomplishes the minimum freshwater cost with a decrease of 25.2% compared to CSS.

咸水介质和冷凝器对带抛物槽式集热器的单作用太阳能蒸馏器性能的影响

摘要 实验研究了咸水介质和冷凝器类型对单斜面太阳能蒸馏器性能的影响。检查了两种太阳能蒸馏器类型；带玻璃冷凝器 (CSS) 的传统太阳能蒸馏器和带镀膜散热片冷凝器 (MSS) 的太阳能蒸馏器。对静水池中的三种盐水介质进行了研究；纯盐水、饱和盐水的沙子和浸没在盐水中的钢丝网。在上埃及的冷热气候条件下，仅在蒸馏器或仍与抛物槽收集器 (PTC) 结合使用的情况下，对这些蒸馏器进行了研究。研究结果表明，利用金属丝网、沙子和散热器冷凝器 (HSC) 提高了静淡水产量和效率。由于使用 PTC、HSC 和沙子，夏季淡水产量的最大上升为 67%、7.3% 和 6%，分别与CSS相比。发现所有静止系统在夏季的效率都高于冬季。此外，与 CSS 相比，使用 HSC 在夏季将静止效率提高 11.6%，在冬季提高 8%。MSS在夏季达到41.95%的最大效率，在冬季达到31.96%，而MSS+沙子+PTC实现了最低的淡水成本，与CSS相比降低了25.2%。
