The Performance Of Heat Absorber From Zinc On The Efficiency

Transcript

The distilled water productivity of the effect of size of the heat absorber from Zinc on the efficiency of double slope solar still. Zinc was chosen to use as heat absorber and was put on the water surface in the second layer of the solar still. The size of Zinc used in the experiment has divided 9 sizes from 10% to 90% of the surface of the water in the second layer of the solar still. The temperature, condensed water and efficiency of solar still were measured and calculated in the experiment. The result was show that using the size of 10% of Zinc absorber has the maximum condensed water at 1.43 liters / day and has the efficiency at 25.99%.The minimum efficiency is 15.02% where size of 90% of Zinc absorber was used the result was also revealed that the efficiency of solar still was decreased according to the increasing of the size at Zinc absorber.
