Research on the Thermo Physical Properties of Lauric Acid-Capric Acid Binary Mixture Phase Change Materials

Lauric acid(LA) and capric acid(CA) were mixed into binary mixture, whose melting temperature was predicted with Schroders equation and tested in step cooling curve method.Then latent heat was tested by DSC, and T-history method was used to test thermal conductivity of binary mixtures, heating and cooling characteristics were studied through expanded perlite(EP) adsorption of binary mixtures.Results show that Schroders equation can be used to predict melting temperature of fatty acid, and binary mixture prepared of 6∶4 molar ratio has a high latent heat and its temperature is within a range that meets indoor comfort temperature.Thermal conductivity and the heating and cooling characteristics of the mixtures reveals that the thermal conductivity of fatty acid phase change material(PCM) is low, which restricts its latent heat release rate.
