Abstract

Today, the use of solar water softeners to produce fresh water has become more important than before and the attention of many people and industries has been drawn to this solar system. Out of about 22 million cubic meters of fresh water produced daily, less than 1% of it is produced using solar energy. The production of fresh and pure water using common methods such as desalination and reverse osmosis is energy-intensive and these methods rely on fossil fuels, but the use of solar water desalination is not only low-cost and It is economical, but it does not need fossil fuel and conserves energy resources.In this study, the absorber of a single-slope solar desalination plant was numerically evaluated in eleven different geometries with the same conditions. The purpose of this research is to find the best way to design the absorber plate in solar water desalination. The result showed that the best mode for making a simple solar water softener is mode (C), in this mode, the temperature of the absorber reaches 349 K due to the intensity of solar radiation of 750 watts per square meter, and the amount of distilled water compared to other There are more states, and then geometry (b) has the best performance.
