REVIEW OF PHASE CHANGE MATERIALS USEFUL FOR THERMAL STORAGE SYSTEM

Abstract

Solar energy is one of the powerful sources of energy considering it’s clean, pollution free and renewable nature compared with fossil fuels. As solar energy is periodic and irregular in nature it gives limitations for its usage. Even in locations with pleasing solar radiation gives only few hours of high radiant incidence per day. One way to enhance upon the shortage of solar energy usage is to use thermal energy storage for solar water thermal storage system. Thermal storage system stores energy when collected amount is excess and it discharges energy when collected amount is inadequate. Sensible and latent heat storage materials are used to store thermal energy. In this paper review of phase change material useful for thermal energy system is studied. Phase change materials, melt and freeze in a narrow temperature range with large heat absorption and release, which is important for many applications in the field of building energy conservation. The latent heat storage of phase change materials is an effective way to reduce energy consumption.
