Abstract

Through tapping into the boundless resources provided by the sea and sun, scientists have created a sustainable and cost-effective drinking water supply using solar-powered desalination. In this manuscript, utilizing gravels, sand and wick materials as the energy storage medium is one of the key sustainability modifications made for bettering the rate of evaporation within solar stills, hence enhancing the freshwater yield. Here, experiments on a single basin solar still with and without energy storage components have been carried out. Typically, energy storage materials are employed to enhance the rate of evaporation in solar stills, aiming to increase the yield of distilled water during nocturnal hours. Consequently, it was observed that using locally available heat storage materials in a solar still during daylight and overnight production of distillate for 15 liter of water input resulted in increases of 54.39 and 58.08%, respectively. In the case of upgraded solar desalination systems, the maximum thermal efficiencies were notably improved, with increases of 90.843, 84.464, and 66.326% compared to conventional solar desalination systems for water inputs of 15, 20, and 25 liters, respectively. The suggested solar still design is particularly well-suited for generating freshwater in regions with a pronounced demand, such as areas characterized by excessively saline groundwater, coastal zones, and rural locations.

单坡太阳能蒸馏器与砾石、砂和芯材的整合研究:实验方法
摘要通过利用海洋和太阳提供的无穷资源,科学家们利用太阳能海水淡化技术创造了一种可持续的、具有成本效益的饮用水供应方式。在本手稿中,利用砾石、沙子和灯芯材料作为储能介质是可持续发展的关键改进措施之一,可提高太阳能蒸馏器的蒸发率,从而提高淡水产量。在此,我们对带有和不带储能组件的单池太阳能蒸馏器进行了实验。通常情况下,采用储能材料来提高太阳能蒸馏器的蒸发率,目的是提高夜间蒸馏水的产量。因此,观察发现,在太阳能蒸馏器中使用当地可用的蓄热材料,在白天和夜间生产蒸馏水,15 升水的输入量分别增加了 54.39% 和 58.08%。与传统的太阳能海水淡化系统相比,升级后的太阳能海水淡化系统的最大热效率显著提高,在进水量为 15、20 和 25 升时,分别提高了 90.843、84.464 和 66.326%。建议的太阳能蒸馏器设计尤其适用于淡水需求量大的地区,如地下水盐度过高的地区、沿海地区和农村地区。
