Performance Analyses of Solar Still Coupled with Vacuum Tubes

Drinking water is necessary to our daily living and for sustainable life. The access of clean water is one of the main issues, especially in most of Asian and African countries. There are necessities to encourage the renewable technologies, such as solar distillation, that is abundant and environmental friendly. The increasing demand on renewable systems usage worldwide and techniques based on effective capturing of solar energy will creates ustainability. Solar stills are depending on distillation process that utilizes solar energy. Solar stills generate pure clean water from brackish water. They are suitable for domestic users in rural regions due to easy operation and maintenance. Their dependence on solar radiation and low yield are behind their wide spread usage. This study is testing the efficiency of the solar still as cleanwater supplier. Hence, a single slope solar-still has been tested for its overall yield with or without coupling with solar vacuum tubes under Jordanian climatic conditions. The results of the experimental tests have been investigated in this study. The main contribution of this study pertains to the analyses of the solar still coupled with vacuum tubes and singles lopeal one both under Jordanian climate conditions. The results of the experimental study showed that the coupling of the vacuum tubes with single solar still has increased the yield by 50% than an uncoupled system.
