Solar Distillation Between A Simple And Double-glazing

Authors : Abderrahmane Khechekhouche. Boubaker Ben Haoua. Zied Driss.


The south-east region of Algeria suffers from a great socio-economic problem that affects a large population. Faced with the unavailability of drinking water, solar distillation; which appears to be a suitable and inexpensive solution; was adopted by local researchers. Improving the productivity of a solar greenhouse distiller is the subject of several researches in the world. As it is well known, distiller with simple glazing is wildly studied but unfortunately has feeble efficiency. Double glazing is a method that increases the efficiency of a flat solar collector. The idea is to use the same technique on a single-slope solar distiller (50 x 50 cm). Two glass plates separated by 1 cm between them air is trapped. Experience shows that this technique has a negative effect on the productivity of the distiller with a rate of 88.63%. So double glazing is not recommended in the single slope solar distiller.
