This paper presents a complete exergy analysis and exergy destruction of a finned acrylic solar still (SS) at 1, 2, and 3 cm salt water depth (W). The coefficients of heat transfer of salt water-glass have been computed for evaporative, convective, and radiant heat transfer. Also, thermal efficiency, exergy loss of basin, saltwater, and glass was determined. The maximum hourly output of a finned acrylic SS at 1, 2, and 3 cm W was1.23, 0.93, and 0.81 kg, respectively. The daily yield of 5.67, 5.16, and 4.41 kg was collected from the finned acrylic SS at 1, 2, and 3 cm salt W, respectively. For the finned acrylic SS at 1 cm W, the maximal exergy loss of the basin, saltwater, and glass was 604.3, 92.8, and 141.8 W/m, respectively. The thermal and exergy efficiency of the finned acrylic SS at 1 cm W is 42.54 and 3.83%, respectively, while at 2 cm salt W, it is 37.92 and 3.22% and for 3 cm W is 31.2 and 2.7%. According to the findings, the exergy loss of saltwater in finned acrylic SS at 1 cm W is minimal when compared to the exergy loss of saltwater in finned acrylic SS at 2 and 3 cm W.
本文对 1cm、2cm 和 3cm 盐水深(W)的带翅丙烯酸太阳能蒸馏器(SS)进行了完整的火用分析和火用损耗分析。计算了盐水-玻璃之间的对流传热、辐射传热和蒸发传热的传热系数。同时,确定了热效率、盆地、盐水和玻璃的火用损耗。在 1cm、2cm 和 3cm W 时,带翅丙烯酸 SS 的最大每小时输出量分别为 1.23kg、0.93kg 和 0.81kg。在 1cm W 时,带翅丙烯酸 SS 的日产量分别为 5.67kg、5.16kg 和 4.41kg。在 1cm W 时,带翅丙烯酸 SS 的盆地、盐水和玻璃的最大火用损耗分别为 604.3W/m、92.8W/m 和 141.8W/m。在 1cm W 时,带翅丙烯酸 SS 的热效率和火用效率分别为 42.54%和 3.83%,而在 2cm W 时,分别为 37.92%和 3.22%,在 3cm W 时,分别为 31.2%和 2.7%。根据研究结果,与 2cm 和 3cm W 的带翅丙烯酸 SS 相比,在 1cm W 的带翅丙烯酸 SS 中,盐水的火用损耗最小。
