Résumé

An appropriate and correct method to determine latent heat and solid-liquid transition temperature of nano-enhanced phase change materials (NePCMs) should be achieved for a proper design of thermal energy storage systems. The phase transition behaviour can be determined via thermal analysis, studying the evolution of the temperature of the samples when heating and/or cooling under different operation conditions. Conventional thermal analysis methods employ small sample sizes to ensure a good accuracy of the measurement. However, use of larger samples helps to match lab-scale tests and applications. In this work, a modified T-history installation was implemented trying to fulfil this lack of study of meaningful size NePCMs samples. The assembly and calibration of the experimental setup is carefully explained. Additionally, T-history tests of n-hexadecane were performed to validate the experimental setup, allowing to obtain enthalpy-temperature curves. Also, results were compared with new measurements using a heat-flux DSC.
