Phase Change Materials (PCM) allow storing thermal energy as latent heat when phase change occurs.
In order to characterize these materials the phase change enthalpy and temperature should be perfectly
known. Differential Scanning Calorimetry (DSC) is the most used technique to determine PCM’s thermophysical
properties. There are mainly two DSC operation modes: dynamic and step mode. A selection of
the two most common PCM materials (paraffin and salts hydrates) was performed to conduct measures
with the two DSC operation modes. The main objective of this paper is to determine the most appropriate
operation mode for each type of PCM. A slow dynamic mode is recommended when analyzing salt
hydrates with DSC. No significant differences between the two DSC modes were observed for paraffin.
