Productivity Enhancement of Solar Desalination System Using Paraffin Wax

P Sundaram and R Senthil

The experimental investigation of solar desalination without and with PCM thermal storage is examined. Solar still is designed with a single basin double slope with East-West orientation. The objective is to study the effect of thermal storage using paraffin wax as phase change material (PCM) in a solar still. The experiment is carried out for the different depth of water at 10, 20 and 30 mm in the basin with and without PCM. The productivity of water at the depth of 10 mm is greater than 20 mm and 30 mm. The productivity is increased to 11.6% and the peak yield is increased by 9.5% with PCM.
