abstract

Thermal storage plays a major role in a wide variety of industrial, commercial and residential application when there is a mismatch between the supply and demand of energy. Several promising developments are taking place in the field of thermal storage using phase change materials (PCM) in buildings. In the present paper, a detailed study of the thermal performance of a phase change material system for energy conservation in building is analyzed and discussed. An experiment consisting of two identical test houses has been constructed to study the effect of having PCM panel on the roof of the building. One house is constructed without PCM on the room in order to provide a reference case for comparison with the experimental house that includes the phase change material. The PCM is an inorganic eutectic mixture, which has melting temperature in the range of 26 - 28°C. A mathematical model has been developed in which finite volume method is used to predict the thermal behavior of the ceiling system incorporating PCMs. A comparison with the experimental results is also made.
