“…In the USSR, several studies and experiments were carried out with solar distillers, especially in Ashgabat (Turkmenistan), where a solar distillation unit was built to produce fresh water for sheep. The facility was fed with salted wells, using an experimental photovoltaic generator that produced electricity to pump the water to the distillers [16][17][18].…”

Water covers 70% of the planet Earth. Of the total volume of water on the planet, 2/3 (two-thirds) is in the form of ice or underground water. On the other hand, fresh water is an increasingly scarce resource in the world, with only 3% of the world's water being drinkable. Data from the United Nations (UN), indicate that approximately 1.1 billion inhabitants on planet Earth do not have access to fresh water. The same data also reveal that 2.7 billion inhabitants suffer from water scarcity for approximately one month a year. According to these data, water scarcity currently affects more than 40% of the world's population. This condition has driven the proposition of technological solutions to minimize the impact of difficulties in accessing this good [1]. Allied to all these aspects, in recent decades, industrial development and the growth of the world population have demanded a greater need for fresh water. At the same time, pollution and the reduction of surface water sources limit access to available freshwater resources [2]. Thus, there is a need for alternative water sources, leading to a focus on using previously technologies, with an emphasis on saltwater desalination. Many areas affected by freshwater scarcity are close to the sea, favoring implementing these technologies.

“…In the former USSR, under the leadership of Doctor of Technical Sciences, Professor Baum V.A, since 1960, experimental research has been carried out on the development and use of solar desalination plants at the Institute of the Sun of Turkmenistan (Baum, 1960, 1961) [ 4 , 5 , 6 ]. In 1968, in the village of Bakharden in the Kara-Kum desert in Turkmenistan, the 1st experimental production solar installation for sheep farms was built.…”

In the hot climate of the Mangistau region, located on the eastern coast of the Caspian, there are no sources of freshwater. Of the available groundwater deposits, only three are suitable for drinking water supply. The scarcity is felt in remote areas and coastal areas, where the population uses groundwater. The provision of the population is carried out by a seawater desalination plant. In the hot summer period, due to high temperatures, the productivity of desalination plants decreases (the water in the channels reaches 30 °C, and the plants are designed for 20 °C). This factor provides opportunities for the development of desalination plants using this heliopotential. Easy to manufacture, environmentally and economically viable solar desalination plants are essential for coastal areas where water is scarce. The article presents the results of experimental studies of the heliosystem, which consists of a passive solar water heater (SWH) and an active solar desalination plant (SW). Water is heated in the SWH pool and supplied to the lower SW pool-1, in which the desalination process is achieved by cooling the water pool-2. By reducing the temperature in the SW volume, the condensation temperature is reached. The coating of 2 layers of glass with an air gap reduces heat losses and raises the temperature in the installations by 10–12 °C and keeps it at night. Horizontal glass coverings provide a large area for solar radiation to enter the pool surface. Heat transfer by convection, in the volume between the "cold" and "hot" basins, is determined using the convection coefficient, which depends on the product of the numbers Gr and Pr. According to the results of experiments, the daily productivity of the desalter was 1.97, 1.83 and 2.31 l/m 2 on the day of July 20, 21 and 22, 2019. The maximum value of the total heat transfer coefficient for SVN was 32.9 W/m 2 °C, for SW 49.4 W/m 2 °C.
