Design and Manufacture Three Solar Distillation Units and Measuring Their Productivity

摘要

In this research, a comparison is made among three units of solar water distillation (M1, M2 and M3), where M1 is a passive solar still, M2 is a passive solar still coupled with flat plate collector and M3 is similar to M2 but it was provided with copper tube inside the still to realize the latent heat. Only the daily productivity factor was used to make a comparison among these units. The results shows that the productivity of M2 is more than it for M1 by 42%, While the productivity of M3 is more than it of M1 by 52%.
