Influence of Operating Parameters on Pyramid Solar Still with Phase Change Material (PCM)

D. Srinivas, Gupta AVSSKS

Abstract


In the recent scenario, distillation with solar still plays a vital role in obtaining potable water from brackish and seawater. The inspiration for this paper is the partial availability of clean water resources and the plenty of available water due to potential renovation into filtered water using solar energy. In this paper, an attempt is made to study the productivity of pyramid solar still. A distillation system was fabricated to achieve this goal, a distillation system was fabricated which incorporates square pyramid fiberglass placed on a black-coated Aluminum basin. The solar radiation, which is incident on the black-coated basin heats the water and evaporates it forming vapors onto the fiberglass cover which is condensed to potable water. For analyzing the performance of still, the distillation system is operated at different water depths viz; 5 cm and 10 cm, along with paraffin wax material and preheated water, The experimental setup is placed at an angle of 50 degrees to the horizontal. The hourly productivity is higher in the case of solar still with PCM during sunny days. From the experimental analysis, it is observed that there is a 75% increase in the efficiency of still, when operated with PCM, at 5 cm depth of water.
