First, different series of tests were performed on non-damaged PCMs (reference) using different masses and heating rates in order to optimize the choice of the experimental parameters used in DSC test. Accordingly, the specific heats at solid, liquid phases and the latent heats of PCMs were obtained. In addition, a fast approximate approach was suggested for the determination of the heat capacity of PCMs from a direct exploitation of the heat flux curves obtained by scanning PCMs at different heating rates. Finally, damaged PCMs were investigated and their thermal properties (specific heat and phase change enthalpy) were compared to the reference PCMs. It was shown from the obtained results that low heating rates are more suitable for PCMs scanning during DSC measurements in order to ensure a thermodynamic equilibrium within the sample. Furthermore, the results highlighted that damage of PCMs can lead to the loss of their specific heat capacity of about 28% compared to the non-damaged PCMs.","10.1016/j.jobe.2015.01.001","2352-7102","http://hdl.handle.net/10985/9744","en","Centre de Paris","Elsevier","Post-print","Phase Change Materials||Thermodynamic properties||Differential Scanning Calorimetry||Heat capacity||damage","Sciences de l'ingénieur: Matériaux||Sciences de l'ingénieur: Mécanique: Thermique","Thermal analysis by DSC of Phase Change Materials, study of the damage effect","Article dans une revue avec comité de lecture","Internationale","1 Year","Journal of Building Engineering","13-19","1","aut||aut||aut||aut","hal-01174646","accept","1"
