Abstract: The use of Phase Change Materials as latent heat storage medium is an effective way of storing thermal energy. PCMs offer the advantages of having high energy storage density and its isothermal nature. PCMs have been widely used in latent heat thermal storage systems for heat pumps, solar systems and spacecraft applications. This Study is undertaken to investigate about the effectiveness of heat transfer using PCMs through storing solar energy for domestic water heating. The experimental setup consist of simultaneous functioning heat absorbing units. One is a solar water heater and the other is a heat storage unit consisting of phase change materials. The storage unit stores heat in PCM during the day and supplies hot water during night hours. This storage unit utilizes thermal storage tank filled with industrial granulated paraffin wax (PCMs) as the heat storage medium integrated with the solar collector to absorb energy. The setup compares the difference in the efficiency of the storage system without using PCMs and using PCMs and thereafter the graphical study of the entire setup is conducted.
