Design and Fabrication of Solar Water Distiller

Abstract

When using a solar still to distil water, a round parabolic absorber has a larger absorber surface area than a flat absorber. A solar energy monitoring system is made possible by its compact design, which increases the quantity of solar heat absorbed and the rate of evaporation inside the distillation chamber. According to recent research, an experimental study was conducted on a solar-powered water distiller with a circular parabolic absorber. The experimental model was developed, built, and tested following the operational meteorological conditions in Damietta, Ras El-Bar City. The water yield and thermodynamic and economic analyses were looked into and discussed. The SWD-PA's highest daily water yield was 2.31 L/(m2.day), with first and second law efficiencies of about 41.7% and 3.021%, respectively. The cost of distillate water for SWD-PA ranged from 0.00213 (L.m2) to 0.00278 (L.m2) at water yields between 2189.8 mL/(m2.day) and 2047.7 mL/(m2.day) at a 20% interest rate. Spending on water decreases by around 6.5 per cent, and water production rises by roughly 7 per cent. The recommended system, which makes use of a circular parabolic absorber, is well-designed, has a high level of performance and output, and can attach a solar tracking system.
