Abstract: The project titled “Fabrication of Heat Storage Unit Using PCM” aims to explore the feasibility and effectiveness of utilizing Phase Change Materials (PCM) for thermal energy storage. Thermal energy storage plays a crucial role in various applications, including solar energy systems, building heating and cooling, and industrial processes. This report presents the fabrication process of a heat storage unit utilizing PCM and evaluates its thermal performance. The project involved the selection of suitable PCM, fabrication of the heat storage unit, and experimental testing to measure its heat storage capacity and thermal performance. Results indicate that the fabricated heat storage unit effectively stores and releases thermal energy, demonstrating its potential for practical applications in energy-efficient systems. The findings contribute to the advancement of thermal energy storage technology and provide insights for future research and development in this field. The use of a latent heat storage system using phase change materials is an effective way of storing thermal energy. In this project a PCM based tube in shell heat exchanger is designed and fabricated. The project focuses on the temperature distribution pattern of the phase change material during the process of charging and discharging the results are obtained by experimentally. Paraffin wax has been used as the phase change material. This type of thermal energy storage system can be used as a medium to store energy and can be used further.
