Abstract:
Solar pond is use to store the heat by creating a gradient of salt. The major problem in salt gradient solar pond is continuous diffusion of salt from LCZ to UCZ. The continuous erosion of salt from high concentration zone to low concentration zone cause of decrease in energy storage efficiency with time. Two experiments were performed on a salt gradient solar pond: one with separator in lower convective zone and other one on conventional solar pond. Both the solar pond has same surface area 0.7m x 0.45m and a depth of 0.4 m. The main purpose of experiment was to compare the performance parameters (saltconcentration, maximum LCZ temperature) with and without using the glass as transparent separator. Experimental data was collected for 15 days period for each setup. On the basis of analysis of experimental data it was found that there is completely elimination of mass diffusion from LCZ i.e. salt concentration of LCZ remains same throughout period of time but on the other hand maximum LCZ temperature achieving time increases due to small decrease in transmittance.
