摘要：Thermal energy storage systems are necessary because the availability of energy like solar is intermittentwhereas the utilization of the thermal energy is continuous. The various methods of storing thermal energy are sensibleheat storage, latent heat storage and thermo chemical storage, among these methods latent heat storage is preferred .Various materials are available to store thermal energy as latent heat ; paraffin widely used phase changematerials(PCM). This is because paraffin maintains its properties even after thousands of charging and dischargingcycles. In this project work, a Shell and helical coil tube type Heat exchanger has been designed and fabricated for lowtemperature HTF(water) using phase change material (PCM) paraffin wax (PW). Experiments were performed for threedifferent mass flow rates and inlet temperature of heat transfer fluid (HTF) is maintained at constant in charging process.In order to recovery of heat during discharging process temperature of HTF is maintained at atmospheric temperature.The effect of mass flow rate on the performance of the system were studied. The amount of heat stored and releasedduring charging (melting of PCM) and discharging (solidification of PCM) were calculated. The experimental resultswere plotted for various mass flow rates.
