“…This is because of the fact that the graphite nanofluid has a 3D absorbing structure, which is good for trapping the light to be absorbed for many times on the graphite flakes surface. 13 On the other hand, the absorption of 0.5% copper oxide nanofluid is around 96%, which is higher than that of the black paint (~94%) by 2% and higher than that of copper oxide particles by about 4.5%.

“…Due to low yield of the SSs, many investigators introduced several scrupulous designs to enhance the output by enhance the evaporation rate of water. Researchers suggested different designs to improve the SSs' performance, such as double slope [3], stepped SS [4,5], SS with phase change materials (PCMs) [6][7][8][9] wick SS [ 10 -12 ] , hybrid SS [13][14][15], stepped SS with continual water circulation [ 3 ] , wind speed [16], SS with storage materials [17,18], SS with nanoparticles [19], SS with PV/T [20][21][22] , and SS with vertical ripple surface [23].…”

Summary The lack of fresh water resources is one of the important reasons obstructing progress all over the world. To overcome this crucial situation, the water desalination system (WDS) is progressed, enhanced, and modified. The desalination plant is mostly powered by nonrenewable energy resources, mainly by fossil fuels that make it an expensive and high‐energy‐consuming technology. Therefore, it is indispensable to depend on renewable energy supplies to drive desalination systems. Recently, the total thermal energy desired to operate the humidification–dehumidification desalination systems can be gained from renewable/sustainable energy resources such as geothermal energy and solar energy. Among the different desalination techniques, the HDH is considered one of the most effective desalination techniques to manage the critical issue of shortage of drinking water. The current paper presents a comprehensive review of diverse types of HDH desalination systems as well as their fundamental components. The present work revealed that the seawater HDH system is a promising technology to produce fresh water, particularly for decentralized demand. The packed bed humidifier is the most utilized type in the HDH water desalination system than other types of humidifiers. Furthermore, the direct dehumidifier enhances the performance of HDH desalination system compared to the indirect one. The present study concludes that the hybrid energy systems have the highest gain output ratio, while the thermal energy systems have the lowest gain output ratio. Water heating with solar energy has a significant enhancement in system productivity compared with solar air heating. The HDH WDS incorporated with heat pump achieves appropriate system productivity and gain output ratio with the lowest cost per liter.

Sharshir et al [9] made use of hybrid solar desalination system where a humidificationdehumidification system was combined with the solar still basin evacuated tube solar water heater system. The drained water from the humidification and dehumidification system was reused in the solar still which helped in achieving about 50% higher distillate output as well as reduce the cost of distilled water.…”

Acute shortage of drinking water has been on the rise owing to increasing population as well as shortage of drinkable water. Generation of potable water using passive solar stills is among the simplest and easier devices which make use of solar heat energy. However, the output of solar still is generally low owing to greater heat loss and needs improvement. In this paper, an experimental analysis is carried out to determine the performance of passive solar still with glass cover cooling using cold water generated using passive evaporative cooling process. The cold water required for cooling the glass cover is obtained using evaporative cooling process in the water tank which is wound with wet cotton cloth wick. The cold water thus obtained is sprayed onto the top surface of glass cover. The experiment is carried out in the outdoor conditions of Dubai from 10:00h to 14:00h and the temperature recordings of basin plate, glass cover, basin water, ambient air and cooling water are noted for every 30 minutes. The results reveal that the average increase in condensation heat transfer coefficient is found to be about 20.8% higher in the presence of glass cover cooling and the distillate output is found to increase by about 3.32 times. The average still efficiency is found to be relatively higher in the presence of cooling which is about 7.3% higher in the presence of cooling. The cold water temperature generated through evaporative cooling process is about 20.4% lower as compared to ambient temperature. Thus, the cooling of glass cover using cold water obtained through evaporative cooling process is found to be effective in enhancing the thermal performance of single basin solar still system.
