| Abstract | ||||
| Two modifications of solar water distiller using cement and aluminum absorber are presented experimentally. The tirst modification using separated condenser to purge the water vapor from the cement absorber distiller to increase the condensation. The second modification using plate thermosyphon charged with acetone installed in the bottom of the water basin in alumiaum absorber distiller to increase the input energy to distiller, thus increasing the water vaporization and condensation. The optimum tilted angle of glazing surface was obtained theoretically between 10-20" at latitude angle of 30'. The daily productivity of cement absorber distiller was obtained of 2.08 U(m2.day) and increased witb percentage of 18.7% using separated condenser. For aluminum absorber distiller the average daily productivity was attained to 2.96 L/(mz.day) and increased to 3.49 L/(mz.day) using plate thermosyphon. The overall efficiency was increased from 50 % to more than 65 % | ||||
