A theoretical evaluation of the heat and mass transfer interchange in an air-inflated solar still has been studied. Experimental verification tests have been carried out and the results compared with theoretical predictions. The percentage of unaccounted heat losses on the overall balance was under three percent for most tests. Continued modification of the theory is necessary in order to account for variations in some of the internal balances.

Abstract Various human activities have led to the consumption of large quantities of pure water, which has led researchers to find efficient and economical methods for desalinating seawater and water containing impurities. In this review paper, solar energy where it is permanent, abundant and environmentally friendly, to produce pure water was discussed using a new solar distillation device, representing the paper’s novelty. The distillation was designed and used in the way led to increase efficiency and improve productivity by adding a solar collector to the system and equipped with a tank containing phase change material (PCM). It has a low melting point and can change the phase by absorbing the system’s latent heat to maintain the system’s temperature. Which contributes to increasing the distillation period even after sunset, thus increasing the daily productivity of freshwater. Using phase change materials will increase distillation hours from (3-4) hours after sunset, increasing the amount of production between (75 - 90) %.

The world is facing the state of being scarce of fresh or drinking water and it is the major problem and global challenge. Along with air and food, water is a basic necessity for human. Solar energy is the biggest source of energy available on earth. A solar distillation is one of the methods for purifying salt water to drinking water. In this method fresh water is obtained by exposing a small layer of salt water to solar radiation and the water vaporized from the basin is condensed on the bottom side of a taper transparent cover. It can be collected in receiving troughs at the end of the still. For this research, a solar still has been designed, fabricated and tested under the climate condition of Coimbatore (11.01680 N, 76.9550 E), India from December 2016 to March 2017. The still basin area was 1m2 and the glass cover of still is inclined at 13 degree based on the city latitude. Solar still is integrated with thermal system such as solar photovoltaic system and then with solar pond in order to preheat the feed water thereby increasing the productivity considerably. Experiments were carried out on the still using different parameters and tested for performance. The results showed that the daily production of the conventional solar still was 2 Lit/m2/day and integrated with photovoltaic system and solar pond was 3.1 Lit/m2/day and 2.54 Lit/m2/day respectively.

Recently, due to global warming and urbanization, there are many major cities that may face the challenge of day zero next decades. Obviously, water is an indispensable component for maintaining life on the earth. Although portable water is required of the hour, the quantity of available freshwater is impacted significantly by sea-level rise and pollution from industrialization. As a consequence of the global water crisis, different methods for clean water production from brackish water have been studied and developed in practice, however, the solar distillation of water is the most economical and desirable approach due to this method utilize solar energy that is the environmentally friendly and economical resource. Over the last 15 years, the impressive price drop of the photovoltaic solar collector (PV/T) makes them popular and easy to access. As a result, the employment of PV/T in solar stills is emerging as a potential device for water distillation. Therefore, in this paper, an active solar distiller combined with a photovoltaic panel has been reviewed for improvement of the distillate yield and effectiveness of solar photovoltaic. This review work presents a variety of studies on various types of solar still (for example conventional solar still (CSS), double slope solar still (DSSS), stepped solar distiller, and cascade solar still) couples with different solar water collectors (such as flat plate collector (FPC) and evacuated tubes collector (ETC)) and solar photovoltaic modules. It is obtained that the hybrid PV/T active solar still improves the distillate yield, energy efficiency, and exergy efficiency as compared to passive mode. The cooling method enhances the performance of the photovoltaic solar collector as well as the productivity of solar still. Moreover, the environmental economic estimation reveals that the solar still coupled with the PV/T mitigated considerably the amount of CO2. It can be stated that it is suitable to commercialize the hybrid PV/T active solar still for supplying not only electricity but drinking water also. Finally, this review paper also suggests the scope for the research in the future.

Abstract Solar distillation is an important technology to get potable water from saltwater using clean and free solar energy. In the current study, an experimental and theoretical investigation of a single-slope traditional solar still was carried out, and the freshwater productivity and thermal efficiency were evaluated for four typical days (19/06, 17/07, 22/08, and 15/09) of 2019 by implementing temperature parameters in different points of the solar still, and the weather parameters such as solar radiation, and ambient air temperature. The study showed an acceptable agreement between the experimental and theoretical results with an average of 6.6% measured deviation of the experimental data. It was noticed that the highest values of productivity were recorded on July 17, 2019.

An experimental investigation on a passive solar still with myristic acid as phase change material (PCM) is carried out to examine the effect of both the mass of PCM and basin water on the daily distillate output and efficiency of the system under indoor simulated condition. Basic energy balance equations are written to predict the water and glass temperatures, daily distillate output and instantaneous efficiency of the single slope solar distillation system with PCM. It is found that the higher mass of PCM with lower mass of water in the solar still basin significantly increases the daily yield and efficiency, but when the amount of PCM exceeds 20 kg productivity reduces. Therefore, a novel and simple of solar stills with PCM is proposed to enhance the overall productivity of the distillation system. The new solar still has increased the distillate output by 35-40%. The use of inner glass cover temperature for productivity prediction has also been investigated, and the prediction shows relatively better agreement with the experimental data.

Shallow Basin

Solar distillation purifies water by transferring sun's heat to a simple device. A shallow basin with a glass shield makes up the majority of the system, which is usually referred to as a solar even now. Evaporation takes place when the pool water is heated by the sun. Humidity rises, condenses on the shield, and drips into a drip tray, leaving salts, minerals, as well as the majority of contaminants behind. The oceans, that have a high salinity, are now the only nearly inexhaustible source of water supply.Separating salts from seawater, on the other hand, necessitates a huge amount of energy, that also, when derived from fossil fuels, can be destructive to the environment. As a result, desalination of seawater must be done using environmentally friendly energy sources. PCM which are solar,  are widely used to store solar radiation during the day and release it in the evening, in a wide range of solar applications
