Abstract

This study explores the potential performance improvements of a tubular solar still (TSS) through innovative design modifications. Three configurations are explored a hanging wick for thin-film evaporation, an evacuated tube solar heater to boost evaporation, and a cover cooling system to enhance condensation. In the first setup, the TSS achieved a daily output of 4.57 L/m², which represents a 38.48 % increase compared to the conventional solar still (CSS) average output of 3.2 L/m². The energy and exergy efficiencies increased to 43.92 % and 3.72 %, respectively, compared to the CSS, which achieved 33 % and 2.1 % for energy and exergy efficiencies, respectively. In the second configuration, the TSS showed further improvement with a daily yield of 8.32 L/m², an increase of 157.5 % over the CSS. In the third configuration (the best case), the daily yield increased from 3.2 L/m² in the CSS to 9.96 L/m², an improvement of 205.48 %. Energy and exergy efficiencies increased to 88.29 % and 9.42 %, respectively. The third configuration has the minimum cost of producing water was 0.0170 $/L alongside 412.79 % enhancement in exergy output (220.43 kWh/year) over the CSS, and five times CO₂ emission reduction (5.29 tons).

采用真空管加热器、薄膜悬挂灯芯和盖式冷却后，创新型管式太阳能电池的4E性能评估得到了增强

本研究探讨了通过创新设计改进管式太阳能蒸馏器（TSS）的潜在性能改进。设计探索了三种结构：用于薄膜蒸发的悬挂灯芯，用于促进蒸发的真空管太阳能加热器，以及用于增强冷凝的盖冷却系统。在第一次设置中，TSS实现了4.57升/平方米的日产量，与传统太阳能蒸馏器（CSS）的平均产量3.2升/平方米相比，增加了38.48%。能源效率和火用效率分别提高到43.92%和3.72%，而CSS的能源效率和火用效率分别达到33%和2.1%。在第二个配置中，TSS表现出进一步的改善，日产量为8.32 L/m2，比CSS提高了157.5%。在第三种配置（最佳情况）下，日产量从CSS的3.2 L/m2增加到9.96 L/m2，提高了205.48%。能源效率和火用效率分别提高到88.29%和9.42%。第三种配置的最低产水成本为0.0170美元/升，与CSS相比，火用输出（220.43千瓦时/年）提高了412.79%，二氧化碳排放量减少了5倍（5.29吨）。

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
