PERFORMANCE EVALUATION ON SOLAR STILL INTEGRATED WITH NANOCOMPOSITE PHASE CHANGE MATERIALS
This paper communicates the performance evaluation o f single slope solar still integrated with nanocomposite phase change materials and compare with the experimental results o f with and without phase change materials. A solar still with lm 2 surface area is developed with поп-selective coating o f absorber sheet with the provision o f thermal energy storage materials. The solar still is tested on typical days with and without thermal energy storage materials. It is found that from the experimental studies that nano-materails (Al20 3) dispersed in paraffin wax is giving better cumulative yield o f distillate than paraffin wax alone and without paraffin wax thermal storage. The daily efficiency o f the solar still is computed for solar still with nano-composite phase change materials is 45% and solar still paraffin wax alone thermal storage is 40% and solar still without any thermal storage is 38%. It is concluded from the experimental studies; solar still integrated with nano-composite phase change materials gives better performance than with and without phase change material alone.
