Experimental Study of Thermal Energy Storage in Solar System Using PCM

Abstract:

This paper summary the investigation and analysis of thermal energy storage extracted from solar heater and use for domestic purpose. Choosing a suitable phase change materials paraffin wax used for storing thermal energy in insulation tank. The tank carries minimum of 45 liters capacity of water and 50 numbers copper tubes each copper tube carries minimum of 100 grams PCM materials. Inside the tank phase change materials are receiving hot water from solar panel. This solar energy is stored in Copper tubes each copper tube contains PCM Materials as latent heat energy. Latent heat is absorbed and stored in Copper tubes .Large quantity of solar energy can be stored in a day time and same heat can be retrieved for later use. The tank was instrumented to measure inlet and outlet water temperature. The differences of temperature of the water is measured in a definite interval of time have been noted then calculating heat transfer rate and system effectiveness. The heat storage system is to be applied to store solar energy and the stored heat is used for domestic hot water supply system.
