This article presents the experimental performance investigation of
solar still integrated with two types of phase change materials namely
Lauric acid and Myristic acid independently, used as storage medium
of solar energy. The experiments were performed during the months of
April-May 2011, under Indian climatic conditions. The effect of input
parameters such as mass of water in basin and mass of phase change
material integrated with solar still basin on productivity of the solar still
has been studied. Also on the basis of the experimental data the values
of exergy and energy were calculated. It has been found that (i) produc-
tivity of solar still integrated with Lauric acid is 22% more than the solar
still integrated with Myristic acid. (ii) the energy efficiencies for solar
still integrated with Lauric acid and Myristic acid are found to be 39.6%
and 34.4% where as exergy efficiencies values are 0.29% and 0.74% re -
spectively (iii) the cost of using Lauric acid is lesser than using Myristic
acid for same amount of productivity.
