Abstract
Thermal energy storage systems are necessary because the available energy like solar is intermittent whereas the utilization of thermal energy is continuous. The various methods of storing thermal energy are sensible heat storage, latent heat storage and thermo chemical storage, among this methods latent heat storage is preferred. Various materials are available to store thermal energy as latent heat; Paraffin is widely used phase change material (PCM) .This is because paraffin maintains its properties even after thousands of charging and discharging cycles. This only disadvantage with paraffin is that its poor thermal conductivity. Increasing the metal nanoparticles composition in the paraffin increasing the thermal conductivity of the system, however there is a limit for blending the metal Nano particles with the PCM also. This is because; higher the metal Nano particle composition, higher will be the chance of agglomeration, which in turn decrease the thermal conductivity of the composite material. The performance characteristics of the thermal energy storage system are (i) Thermal conductivity of the PCM, (ii) Charging period and (iii) discharging period of thermal energy storage system. In this work, it is proposed to determine the suitable proportion of metal Nano particles that can be blended with paraffin PCM and analysis the performance of thermal energy storage system selected.
