PARAMETRIC STUDY OF AN INVERTED ABSORBER DOUBLE-EFFECT SOLAR DISTILLATION SYSTEM

An analysis of an inverted absorber double-effect solar still is prese nted. Energy balance equations have been written, and analytical expre ssions for water and condensing cover temperatures and the hourly yiel d have been derived. Numerical computations have been carried out for a typical day in Delhi. The results thus obtained have been compared w ith those of the conventional double effect (double basin) solar still . It was observed that an inverted absorber solar still gives a higher output than the conventional double-effect one.
