Abstract
Thermal energy storage is required when there is mismatch between energy supply and demand. Thermal energy is stored in sensible and latent form. Latent form has a potential to store energy in isothermal nature with high energy density. Latent heat storage (LHS) using phase change material (PCM) is proposed to achieve objective of high storage density with higher efficiency. Quantitative information on heat transfer and melting/solidification processes are required for proper designing of thermal energy storage (TES) systems. The poor thermal conductivity of PCM drastically affects thermal performance. Purpose of this project is to investigate performance enhancement of LHS unit suitable to a solar water heater application. Performance of LHS is experimentally evaluated by varying geometrical parameters. Fins provided with LHS and their variations; orientations, fin length , fin material as a geometrical parameters.
