中文摘要
摘要 全球范围内，水资源短缺是一项严峻的环境问题。相较于反渗透、热法海水淡化、废水回用以及大气取水装置，太阳能蒸馏器因其低成本和低环境影响，为解决此类环境问题提供了更优的方案。本研究旨在探讨采用多种储能材料（包括低碳钢、铸铁和铜）与竹质灯芯材料相结合的方式，对倾斜式太阳能蒸馏器（ISS）的能量效率、产水性能及㶲效率的影响。研究设置了多个案例进行比较分析，以确定最佳性能配置：案例1为传统ISS；案例2为带竹质灯芯材料的ISS；案例3为带竹质灯芯与低碳钢的ISS；案例4为带竹质灯芯与铸铁的ISS；案例5为带竹质灯芯与铜质储能材料的ISS。研究结果表明，在水产量、能量效率和㶲效率方面，案例5的表现优于所有其他案例。案例5实现了最高的累积产水量，达到4953毫升，分别比其他各案例高出53.8%、41.2%、26.7%和10.1%。案例5获得的最大平均效率为53.6%。与案例1、2、3和4相比，案例5的平均能量效率分别高出49.5%、31.3%、19.3%和8%；其平均㶲效率则分别高出132.9%、56.4%、22.1%和8%。根据对倾斜式太阳能蒸馏器的经济性分析，每升蒸馏水的生产成本为0.023美元。同时开展的经济与环境分析结果表明，案例5配置下的ISS系统效率是传统ISS系统的1.21倍。
English Abstract
Abstract Worldwide, water scarcity is a serious environmental issue. Solar stills offer a better solution for these environmental problems, with low cost and low environmental impact compared to RO and thermal desalination, wastewater recycling, and atmospheric water generators. The purpose of this study is to investigate the energy, productivity, and exergy efficiency of inclined solar still using a combination of several energy storage materials, including mild steel, cast iron, and copper, with bamboo wick material. The study uses several cases, including Case 1: Conventional ISS; Case 2: ISS with Bamboo Wick Material; Case 3: ISS with Bamboo and Mild Steel; Case 4: ISS with Bamboo and Cast Iron; and Case 5: ISS with Bamboo Material and Copper Energy Storage Material, to compare and determine the best performance. According to study findings, Case 5 outperforms all other cases examined regarding water productivity, energy, and exergy efficiency. Case 5 achieved the highest cumulative productivity of 4953 ml, which is higher than the other cases by 53.8, 41.2, 26.7, and 10.1 %. The maximum average efficiency attained is 53.6 % by case 5. In comparison to cases 1, 2, 3, and 4, case 5′s average energy efficiency is 49.5, 31.3, 19.3, and 8 % higher; in addition, case 5′s average exergy efficiency is 132.9, 56.4, 22.1, and 8 % higher. According to an economic analysis of inclined solar stills, distilled water costs 0.023$ per litre. An economic and environmental analysis of inclined solar stills has been conducted and the findings indicate that the ISS with case 5 is 1.21 times more efficient than the conventional ISS system.
