Abstract

Artificial solar ponds are saline water ponds that about 1.5-3 m depth contains salt water in increasing intensity. Solar ponds are genarally comprise of three zones. These are upper convective, non convective and bottom convective zones. Upper convective zone is composed of fresh water. Non convectine zone is insulated zone which contains different density salty water that increase in downward, and bottom convective zone is contain higly intensity solar water that storage and absorb solar energy. Incoming solar light a part of the solar pond surface is reflected from the upper convetive surface, the remainder solar light goes to down to solar pond. This time various wave length of light absorption in the different rates at different depths and 25-35% of this light is reached in down. In this study, a cylindrical solar pond system (CSPS) with a radius of 1.6 m and a depth of 2.0 m was built in Çukurova University in Adana, Turkey. The Solar ponds entering of sun light that occurs in each layer to determine the refraction angles is a theoretical study. According to the analysis results, into stored of solar radiation, for upper convection zone entering light and angle of refraction values respectively Qi: 30°, 45°, 60° and Qk: 13.3°, 19.6°, 24.3°. For non convection zone entering light and angle of refraction values respectively found Qi: 13.3°, 19.6°, 24.3° and Qk: 9.02°, 13.22°, 16.24°.
