“…The heat exchanger improved the performance in terms of the distillate productivity of the solar still. Dhivagar and Sundararaj [58] modified a solar still coupled with a copper material heat exchanger, using a coarse aggregate as an energy-absorbing material, as shown in Figure 4. They concluded that the modification of the solar still produced 28% and 17% higher efficiencies compared with the conventional solar still.…”

Solar desalination is a process to convert saline water into potable water by the application of solar energy. The enhancement of the distillate output of the solar desalination is low, so it is not considered as a method to produce potable water. A heat exchanger is an important device used for heat transfer applications. The present review article illustrates the application of a heat exchanger with a solar desalination system to enhance the distillate output. In the current review, it is found that the heat exchanger is an important device to improve the distillate productivity of the solar desalination system. Finally, the future work and future challenges of using a heat exchanger with a solar desalination system are presented.

The use of different energy storage materials can have a high effect on the water productivity of solar desalination. This study evaluates the impact of magnetic powders on modified solar still (MPSS) performance and compares the results with conventional solar still (CSS). Black iron oxide magnetic powder was selected to increase solar radiation absorption. The black iron magnetic powder simultaneously acts as a thermal storage material and a porous absorber medium. The thermal energy stored in the magnetic powder improved the performance of the MPSS during peak solar irradiation hours, resulting in higher productivity. The results showed that the thermal performance of MPSS was higher than CSS. The MPSS exhibited a 39.8% higher evaporative and 14.5% higher convective heat transfer rate compared with CSS. Results showed that the cumulative water productivity of MPSS was 31.2% greater than CSS. Also, the energy and exergy efficiencies of MPSS were improved by 18.9% and 19.04%, respectively, compared with CSS. Moreover, the predicted payback period in MPSS and CSS were 3.2 and 4.3 months. Additionally, the CO 2 reduction of MPSS was improved by approximately 45.53% compared with that of CSS. The results also showed that the exergoeconomic parameter of MPSS and CSS with energy base was equal to 33.1 and 24.56 kWh/$, respectively.

We humans find solutions for every problem around us. Taking an environmental problem for water scarcity we have come up with a traditional idea but a bit modified. We have used solar distillation as the basic concept and developed a single slope single basin solar still (SSSBSS) where we have used a storage material that is rarely used for this process and have carried out the research work in it. The experimental study is carried for a single slope single basin solar still (SSSBSS) under two cases (i) SSSBSS (ii) SSSBSS with zeolite crystals as storage materials. The still was made of galvanized iron (GI) and the sides were insulated with polystyrene. It has a basin area of 1 m2. Bore water of Coimbatore which is a bit salty was taken as the feed water. The test was carried out at Kuniyamuthur, Coimbatore during 10th, 11th, 12th of February 2021. Even though it was winter, the output was average. By the comparison using zeolite crystals, the efficiency was doubled compared to the first case.
