摘要

利用被动式太阳能蒸发器(PSS)将盐水转化为纯净水是一项巨大的挑战,因为其生产率较低。提高生产率的方法之一是降低舱室的容积热容量。被动式太阳能蒸发器的生产率随着最小水深和玻璃罩与未处理水之间的最大温度梯度而激增。本研究对具有三种不同水舱深度的 PSS 进行了比较研究。首先,记录正常 PSS 的生产情况,然后通过在舱内放置水盘来改变舱深。最后,通过在舱内提供可拆卸的支架来调整舱深。实验在印度泰米尔纳德邦纳格科尔(Nagercoil)(北纬 8.1833°,东经 77.4119°)进行。分析了蒸馏水产量的变化。实验数据显示,水盘高度为 40 毫米的 PSS 产量高于其他两种深度的水舱。40 毫米高度水盘的最大蒸馏水产量为 2360 毫升/平方米/天,普通舱为 2000 毫升/平方米/天,70 毫米高度水盘为 1600 毫升/平方米/天。40 毫米高度水盘的能源回收期和蒸馏水生产成本分别约为 1.43 年和 2.75 卢比/立方米。

Evaluation of single slope solar still with different cabin depths with the minimum basin water level
The conversion of saline water into pure water by employing passive solar still (PSS) is a big challenge due to its low productivity. One of the methods to enhance productivity is decreasing the volumetric heat capacity of the cabin. The productivity from the PSS surges with minimum water depths and the maximum temperature gradient between the glass cover and unprocessed water. This work signifies a comparative study of PSS having three different cabin depths. First, the production of normal PSS is recorded and then the cabin depth is modified by the step provided in the cabin itself by placing the water tray on it. Lastly, the cabin depth is adjusted by providing detachable supports inside the cabin. The experiments were carried out in the location of Nagercoil, Tamil Nādu, India (8.1833° N, 77.4119° E). The variation in still production is analyzed. The experimental data shows that the production of PSS with a 40 mm height water tray is more than the other two cabin depths. The maximum distilled water output obtained is 2360 ml/m2 per day for a 40 mm height water tray, 2000 ml/m2 per day for the normal cabin, and 1600 ml/m2 per day for a 70 mm height water tray. Energy payback time and distilled water production cost of the 40 mm height water tray were around 1.43 years and Rs. 2.75/m3, respectively.
