摘要
An experimental study has been carried out toward the development of a multiphase-change material by combining two fabricated microencapsulated phase-change materials (n-octadecane and n-eicosane) samples. The study also covered the characterization of the developed samples for their thermal properties. For the purpose of validation, the thermal properties of the developed multiphase-change material sample were compared with that of the core components. The developed multiphase-change material sample achieved a combined energy storage capacity of 186kJ/kg with two melting temperatures of 23.4 and 34.5 degrees C. Even though the two melting temperatures of the multiphase-change material were slightly reduced by 0.18 and 0.48 degrees C in comparison with the microencapsulated phase-change materials (n-octadecane and n-eicosane), respectively, their mean energy storage capacities were in perfect agreement. The study has therefore shown that it is possible to overcome some of the scientific barriers toward the development of multiphase-change materials, but further investigations are needed to enhance overall thermal response.
