Abstract

Despite the many advantages of solar stills, the limited productivity poses a serious challenge. This motivates scholars to find solutions to reduce this obstacle using different enhancement techniques. From this standpoint, this study aims to enhance the productivity of a single slope solar still (4S) using three different wick materials, tested for the first time together under the same conditions: sponge, jute cloth and luffa fiber. To achieve this aim, two identical 4Ss were manufactured from locally available materials, one conventional (without wick) and the other modified (with wick). All tests were conducted in outdoor conditions of Baghdad city and on sunny days, mostly in April. According to the analysis of productivity, energy, exergy, and economic, it was found that the best performance of 4S was with the use of jute cloth wick. Compared to conventional 4S, productivity was enhanced by 5.07 %, 21.08 % and 17.09 %, energy efficiency was enhanced by 4.77 %, 22.06 % and 20.53 %, exergy efficiency was enhanced by 17.30 %, 25.00 % and 22.54 %, and overall gain of the 4S was enhanced by 6.00, 23.49 and 15.54 % with sponge, jute cloth and luffa fiber respectively.

使用灯芯材料提高单斜面太阳能蒸馏器的性能：与能源、能源和经济分析的比较实验研究

尽管太阳能蒸馏器有许多优点，但其有限的生产率构成了严峻的挑战。这促使学者们寻找解决方案，使用不同的增强技术来减少这一障碍。从这个角度来看，本研究旨在提高单坡太阳能蒸馏器（4S）的生产率，使用三种不同的灯芯材料，首次在相同条件下一起测试：海绵、黄麻布和丝瓜纤维。为了实现这一目标，用当地可用的材料制造了两个相同的4Ss，一个是传统的（没有灯芯），另一个是改良的（有灯芯）。所有测试都是在巴格达市的室外条件下和晴天进行的，主要是在4月进行的。通过对生产效率、能源、能源、经济等方面的分析，发现使用黄布灯芯的4S性能最好。与常规4S相比，使用海绵、黄麻和丝瓜纤维的4S产量分别提高了5.07%、21.08%和17.09%，能效分别提高了4.77%、22.06%和20.53%，火用效率分别提高了17.30%、25.00%和22.54%，总增益分别提高了6.00%、23.49%和15.54%。
