Abstract:
This research have objective for build mathematical modeling for machine using solar energy and
compare result with mathematical modeling of medicinal salt machine using solar energy. The
distillation unit was consisted an incline, 17? at horizontal, single glass with 1 m2
area and installed the focus glass on both side. The area for absorb solar energy was 1m2 (1 m x 1 m).
It was installed
convex mirror in two sides by four sides and was insulated by fiber glass 50 mm thicknesses. This
research was compared experiments between mathematical modeling of medicinal salt machine
using solar energy. The follows error ,distillation 8.53% ,temperature of water in medicinal salt
machine 2.44%,temperature glass of medicinal salt machine using solar energy 3.69% and mass
salt 2.5% . The initial mass of salt water in system was 2,000 cc, 3,000 cc and 4,000 cc for focus
glass and without focus glass. The results showed that the maximum system efficiency at salt water
3,000 cc and the salt water distillation was consisted with water and salt. When the solution was
heated then only water was transformed into steam. The steam would be condensed to become
liquid which was pure distilled water but salt was still in status of solution. That was the cause of
separation water from salt. Volume of distilled water was equal to 1,749 cc, mean was equal to
58.3%. Volume of salt was equal to 1,060 gm, mean was equal to 35.33%. The highest intensity of
solar energy was equal to 734.7 W/m2, mean was equal to 534 W/m2. Totality was equal to 93.63%
and the loss was equal to 6.37%.
