Abstract This paper experimentally investigates the performance of conventional single slope solar still and the impact of integrating a flat plate collector (FPC) as well as parabolic trough collector (PTC) supported with a packaged glass ball layer (PLGB), which acts as a thermal storage medium to the systems. The incident solar energy from the PTC-FPC is collected by two separate loops of finned pipes acting as heat exchangers in still basin. Experiments were conducted during winter and summer seasons with saline water depth of 50 mm. Results revealed that solar still integrated with PTC, FPC and PLGB has a higher freshwater production rate of 6.036 kg/m2/day during summer and 2.775 kg/m2 in winter. Moreover, FPC-PTC-PLGB solar still found to have increased productivity by 172% in winter and 203% in summer, compared to conventional solar still. The efficiency in winter for the solar still with FPC-PTC-PLGB is found to be 16.24% compared to 21.83% in summer, which is higher than the efficiency of conventional solar still at 8.1% (winter) and 12.15% (summer). An economic analysis was carried out for all different parameters investigated to confirm the feasibility of integration of FPC-PTC-PLGB. The price of one liter water produced from conventional solar still (CSS) was $0.067 whereas for the developed solar still (DSS) it was $0.22.

平板集热器、抛物槽和填充床组合的单斜面太阳能蒸馏器的试验研究与评价

摘要 本文通过实验研究了传统单斜面太阳能蒸馏器的性能以及集成平板集热器 (FPC) 和由封装玻璃球层 (PLGB) 支撑的抛物槽集热器 (PTC) 的影响，该玻璃球层充当热源。系统的存储介质。来自 PTC-FPC 的入射太阳能由两个独立的翅片管回路收集，这些翅片管充当静盆中的热交换器。实验在冬季和夏季进行，盐水深度为 50 毫米。结果显示，与PTC、FPC 和PLGB 集成的太阳能仍然具有较高的淡水生产率，夏季为 6.036 kg/m2/天，冬季为 2.775 kg/m2。此外，与传统太阳能蒸馏器相比，FPC-PTC-PLGB 太阳能在冬季和夏季的生产率仍提高了 172% 和 203%。使用 FPC-PTC-PLGB 的太阳能蒸馏器的冬季效率为 16.24%，而夏季为 21.83%，高于传统太阳能蒸馏器的 8.1%（冬季）和 12.15%（夏季）的效率。对调查的所有不同参数进行了经济分析，以确认 FPC-PTC-PLGB 集成的可行性。传统太阳能蒸馏器 (CSS) 生产的一升水的价格为 0.067 美元，而开发太阳能蒸馏器 (DSS) 的价格为 0.22 美元。
