The Performance of a Single Slop Solar Distiller When Using a Two Reflector

Abstract

The lack of safe drinking water is a major problem in many areas. Most of which located within the range of high solar sun and the enormous potential of solar energy can be exploited to turn salt water into drinking water. The most economical and easy way to achieve this goal is to use solar distillation. Two low-cost "Single Slope" solar distillers were designed to examine the impact of adding concentrates and reflectors on daily yield and efficiency and then compare the results. Results obtained from practical experiments have shown that solar distillers with internal and external reflectors made of mirrors have increased in efficiency by 6% and 12% when one liter and two liters of river water are added, respectively, from the distiller under the effect of the parabola concentrator. The daily yield was also (60 and 240) ml higher for the solar distiller, which contained both internal and external reflectors.
