Abstract
The main obstacle to human life in the modern age was the unequal distribution of drinking water on Earth. The demand for drinking water is increasing due to population growth and industrial exploitation, while supply levels are essentially unchanged. Because of its simplicity in construction, techno-economic advantages, and environmental friendliness, solar energy is still regarded as one of the best methods for turning saline into potable water. The main disadvantage of using solar energy as a regular freshwater source was its lower production. Therefore, the most effective method of turning brackish water into drinkable water is to use solar stills in conjunction with PCM, and SWF, which increases the water’s surface area. Two solar stills have been tried to be constructed as part of the current experimental investigation. The outcome of the current investigation reveals that the total output of the different solar still instances was grouped in decreasing order as CSSSS, still-1, still-2, still-3, still-5, and still-4, with daily values of 1330, 1890, 2260, 2555, 2980, and 3555 ml/day. The total output of still-4 was 167% higher than CSSSS, still-1, still-2, still-3, and still-5, and 88% higher, 57% higher, 28% higher, and 19% higher, respectively. The average efficiency follows as: CSSSS (15.9%), still-1 (19.84%), still-2 (22.98%), still-3 (25.81%), still-4 (32.67%), and still-5 (28.46%). The exergy efficiency achieved for CSSSS, still-1, still-2, still-3, still-4, and still-5 was 6.28%, 9.3%, 10.2%, 10.8, 14.95, and 11.25%, respectively.
