Performance Analysis of Thermal Energy Storage Device using Phase Change Material

In thermal energy storage, the useful energy from the collector is transferred to the storage medium where it is transformed into an internal energy. This may occur in the form of latent heat, sensible heat, or both. Latent heat storage is more attractive than sensible heat storage because of its high storage density with smaller temperature swing. This research work deals with a latent heat storage system using Phase Change Materials (PCM) as an effective way of storing thermal energy (solar energy, off-peak electricity, and industrial waste heat). It has the advantages of high storage density and the isothermal nature of the storage process. This research will show performance analysis of thermal energy storage using PCM for various purposes with ways to enhance the heat transfer, and it will show a designs to store the heat using PCMs for different applications, i.e. space heating and cooling, solar cooking, greenhouses, solar water heating and waste heat recovery systems. It will also help to find the suitable PCM for heat exchanger with ways to enhance the heat transfer and provide the various designs to store the heat using PCM for different applications. It will also show the comparative study of the performance conventional system and system with thermal energy storage with PCM.
