1. Introduction: Demand of heat energy increased greatly in different fields of engineering during the last decade. Cooling and heating demand has already been increasing due to the evolving comfort expectations and technological development around the world. Climate change has brought additional challenges for cooling and heating systems designers. Efficient and economical technology that can be used to store large amounts of heat or cold in a definite volume is the subject of research for a long time. Thermal storage plays an important role in building energy conservation, which is greatly assisted by the incorporation of latent heat storage in building products. Devices which store heat during peak power operation and release the same during reduced power operation. Phase change material is one of the thermal
