A Systematic Investigation on Evaporation, Condensation and Production of Sustainable Water from Novel-Designed Tubular Solar Still

In the current scenario, mammoth task is the management of the potable water supply. Clean water is considered to be the fundamental need for humans. In this study, we explore the performance of new design for the solar desalination integrated with parabolic-line concentrator. The newly designed system consists of two separated chambers, i.e. the evaporation and condenser chambers having evacuated tube placed at the focal line of the parabolic trough collector and thermic oil as a heat transferring medium. A newly designed steam separator was used to separate steam and hot water in the condensation chamber. A set of experiments was carried out to investigate the evaporation, condensation and distilled water production performance, independently. The temperature obtained at the copper tube surface was 135 ℃. The temperature of condenser plate was found to be 35 ℃. The results revealed the dependence of evaporation, condensation and water production on the surrounding air temperature. The results compared to the conventional system revealed in an increase of approx. 40% giving a yield of 7.08 l/m²/day. The reported design can be used to change the face of water desalination system throughout the world.
