“…It was concluded that using NF passing through the solar heating system is an advantage provided by the temperature is above 70 • C and in this case, the productivity can be raised up to two times compared to that of an SS without a heat exchanger. Shehata et al [31] integrated an SS with an ETC using ultrasonic humidifiers, PCMs, and reflectors. They also applied a photovoltaic panel to supply the power for running the humidifiers.…”

The sun is the primary source of life on the earth. The heating effect of the sun provides a more fruitful environment for mankind. In addition, solar energy in the form of thermal radiation has been utilized for solar thermal applications and space heating. With abundant solar radiation, the emergence of the solar desalination has been emerged as a viable solution for water purification by utilizing solar stills. However, solar-powered distillation is relatively a slow process due to the requirement of bulk heating. To suppress thermal conduction to bulk water, various photothermal materials were employed. However, there are many governing parameters which influence the productivity, including solar intensity, cloud, wind, ambient air temperature, humidity, solar absorption of blackened surface, depth of bulk water, feed water type, angle of condensation surface, water film thickness, underneath the condensing surface, and experiment period. Further, systematic and continuous experiments for extended periods are essential for determining the stability and durability of a solar desalination system. The main objective of this article is to review all the experimental studies conducted for two months at minimum up to 1-year duration. In addition, all the SDSs handled in this study further were examined by solar geometrical factors, including day length (DL) and position of the sun or zenith angle (θ z ). As a result, the sunshine hours, day length, and the solar zenith angle play an important role in the water evaporation rate. Lower solar zenith angle and longer day length (more sunshine hours) are desirable for higher water productivity.

“…𝐹𝐴𝐶 = 𝐶𝑅𝐹 * 𝐶𝑆 (7) The salvage value of water distillate was considered 0.2 of the Capital cost (CS) [24], so, the annual salvage value (ASV) calculated as: 𝐴𝑆𝑉 = 𝑆 * 𝑆𝐹𝐹 (8) We also considered that the annual maintenance cost (AMC) was 0.15 of the first annual cost (𝐹𝐴𝐶), so, the annual cost (AC) was calculated as [25]: 𝐴𝐶 = 𝐹𝐴𝐶 + 𝐴𝑀𝐶 − 𝐴𝑆𝑉 (9) The yearly cost per liter (𝑌𝐶𝑃𝐿) is as follows: 𝑌𝐶𝐿 = (10) where L is the annual production of fresh water from the suggested solar distiller.…”

Experimental Study of a Tilt Single Slope Solar Still Integrated with Aluminum Condensate Plate

The low freshwater productivity of a conventional solar still is considered a challenge for researchers due to the high temperature of the glass cover or basin water depth. In current work, a newly designed solar still was suggested according to the climatic conditions of Yekaterinburg/Russia, which included an enhanced condensation and evaporation process by spraying a thin water film on a hot absorber plate and then passing the generated water vapor by free convection over the aluminum plate (low temperature). The distillation system under study was tested during July 2020 and 29 July was chosen as a typical day from 08:00 a.m. to 8:00 p.m. The results showed that the largest amount of water vapor condenses on the aluminum plate (about 46%), and the rest condenses on the glass cover. This means that the aluminum plate effectively improved productivity due to the flow of humid air naturally (free convection) on the aluminum plate (its surface temperature was lower than that of the glass cover). The cost analytical calculations showed that the cost of producing one liter of distilled water from the suggested solar still was 0.063$.
