PERFORMANCE ANALYSIS OF THE SINGLE BASIN DOUBLE SLOPE SOLAR STILL INTEGRATED WITH SHALLOW SOLAR POND

In this paper, an attempt has been made to enhance the productivity of the single basin double slope solar still by integrating with shallow solar pond. The performance of the single basin double slope solar still integrated with shallow solar pond has been analyzed theoretically and experimentally. The experiments have been carried out from January to march 2012. The energy balance equations have been written for different temperature elements of the solar still such as glass cover, basin water and still basin. A computer program has been written for analytical solutions of the energy balance equations to evaluate the numerical results of the elements of the still. The productivity and efficiency of the solar still integrated with and without shallow solar pond has been found. It is found that the productivity of the solar still integrated with shallow sola pond is increased compared with the still without integration. The productivity of the solar still integrated with and without shallow solar pond is found to be 5.09 L/m 2 day and 3.17 L/m 2 day and the theoretical results are in good agreement with the experimental results.
