In order to accurately assess the composite PCM’s thermal properties, five composite PCM samples were tested by the DSC method. Fig. 10 displays the measured DSC curves of the five samples.
In addition, the onset phase change temperatures and latent heat values during the melting and freezing phase change processes are also summarized in Table 3.
In Fig. 10, it can be seen that the measured five DSC curves overlap with slight deviations.
It indicates that the paraffin can be uniformly impregnated into the EVM-800 particles.
Theoretical latent heat (LT) of the composite PCM can be calculated as follows [9,11]
