EVAPORATIVITY AND PRODUCTIVITY OF A NEW TUBULAR SOLAR STILL
A Tubular Solar Still (TSS) has being developed by our research group and a transparent vinyl chloride sheet of 0.5mm in thickness was used for the tubular cover of the first model designed by Islam KMS (2007). Since then we have been improving the first model from the viewpoint of assembly, economy and maintenance. A polythene film of 70 μm in thickness was,therefore, adopted as the cover of the second model. As a result, the cover weight of the second model was one twelfth lighter than that of the first model. An experiment was carried out to investigate the evaporation and production performance of the second model and the thermal properties of the tubular cover, humid air and water in a trough inside the still. It was revealed that the hourly evaporation and production fluxes became a little lower for the second model than the first one under the same conditions of ambient air temperature and relative humidity and radiant heat flux. One of the reasons would be the difference in the water depth between the two experiments. Another possible reason of reducing the productivity would be the stagnant of the condensed water due to the undulations of the polythene film.
