Experimental Validation of Fresh Water Production Using Triangular Pyramid Solar Still with PCM Storage

Abstract:

In the study work effect of PCM on the triangular pyramid solar still was experimentally investigated for the climatic condition of Chennai. Experimental studies were conducted and the use of PCM on storage was compared with a solar still without PCM and the PCM used is paraffin wax. The latent heat energy storage is increased with the use of paraffin wax while the energy stored is utilized during the absence of solar radiation by rejecting its heat through the basin to water for further evaporation. The temperatures of various elements of the solar still were measured using a thermocouple. Results show that there is an increase in productivity of 20% when compared to the solar still without PCM.
