A detailed exergy analysis of a conventional and copper finned acrylic solar still has been presented in this manuscript. The evaporative, convective, and radiative heat transfer coefficient of water-glass has been calculated. Also energy efficiency, exergy destruction of basin, water, and glass has been determined. Conventional acrylic solar still with fins produced maximum hourly output of 1.24 kg and it produced daily output of 5.08 kg. The conventional acrylic solar still without fins produced maximum hourly output of 0.94 kg and it produced daily output of 3.75 kg. The maximum exergy destruction of the basin, water, and glass for the conventional acrylic solar still with fins are 655.206, 83.35, and 90.48 W/m, respectively, and conventional acrylic solar still without fins are 616.28, 122.34, and 48.64 W/m, respectively. The energy and exergy effectiveness of the conventional acrylic solar still with fins are 32 and 2.81%, respectively, and without fins are 24.93 and 1.69%, respectively. The study reveals that exergy destruction of water in the case of still with fins is minimum as related to the exergy destruction of water in the case of still without fins.
本文对传统铜翅片式亚克力太阳能蒸馏器和铜翅片式亚克力太阳能蒸馏器进行了详细的分析。计算了水玻璃的蒸发、对流和辐射传热系数。还确定了能效、盆内、水和玻璃的火用损耗。带翅片的传统亚克力太阳能蒸馏器每小时最大输出量为 1.24 千克，日产量为 5.08 千克。不带翅片的传统亚克力太阳能蒸馏器每小时最大输出量为 0.94 千克，日产量为 3.75 千克。带翅片的传统亚克力太阳能蒸馏器的盆、水和玻璃的最大火用损耗分别为 655.206、83.35 和 90.48 W/m，而不带翅片的传统亚克力太阳能蒸馏器的盆、水和玻璃的最大火用损耗分别为 616.28、122.34 和 48.64 W/m。带翅片的传统亚克力太阳能蒸馏器的能量和火用效率分别为 32%和 2.81%，而不带翅片的传统亚克力太阳能蒸馏器的能量和火用效率分别为 24.93%和 1.69%。研究表明，带翅片的太阳能蒸馏器中水的火用损耗最小，而不带翅片的太阳能蒸馏器中水的火用损耗最大。
