Abstract

Solar desalination systems are a kind of water purification system that can be utilized in dry regions. However, the low efficiency and performance of these systems are some of the main challenges of these mechanisms that affect their development. So In this paper, a novel modified model is presented for increasing the efficiency and performance of these systems. This suggested modification is based on a triple action. The first of these actions includes discovering the optimal location for the installation of the solar still water. Increasing the contact surface of the water by spraying and keeping the saltwater in a wide solar still is a second approach for increasing the evaporation of water. In the end, a modern condensing system based on an innovative fog (water particle) trapper/harvester. This system includes fog fences, a cool water pipe loop based on the outdoor temperature, and forced-controlled airflow. Therefore based on this method, a conceptual design of the solar still water is modeled For UAE. The results of this study show that the modified solar still can make 3.94 liter/m2 per day. The cost per liter of each liter of water is $ 0.0344. These results are shown that the efficiency of the proposed model is two times higher than the traditional method with the same cost. Also, these results are in an acceptable range in comparison with the new modified models presented by researchers.
