Preparing and studying of phase change energy storage materials

The thermal energy storage phase change material used for building has been prepared with a few of fatty acids based on the principle of binary low eutectic point. The thermal behaviors such as phase transition temperature and enthalpy of compound energy storage material are researched through differential scanning calorimeter (DSC) and scanning electron microscope (SEM). The results show that the thermal energy storage phase change composite material can be used in the wall panels well as its higher latent heat.
