Experimental Study of Thermal Energy Conservation by using PCM and Its Composites

The system works on the basic concept of conservation of energy within the system. The heat energy taken for changes its (PCM) phase from solid to liquid from the hot water source. After long time this latent heat is utilized to maintain the temperature of the water for long time. Thermal energy storage performance of the composite PCM was tested in a latent thermal energy system. The thermal energy storage charging duration for the composite PCM was reduced obviously compared to paraffin. Here We need to find method to improve PCM of thermal properties by using graphite particles as heat transfer rate enhancers by store the heat energy while the hot fluid are flow. Depends on our results, it may be fulfilled that the equipped PCMs can be regarded of use heat storage materials for some purpose in energy storage system. It can be resulted that by adding graphite particles to improve thermal properties are improved in comparison with pure PCM.
