Through Eq. (1) and the paraffin latent heat values given in Table 3, the theoretical latent heat values of the composite PCM
are calculated as 75.6 J/g in the melting phase change process and 74.9 J/g in the freezing phase change process.
The measured latent heat values of the composite PCM are 77.6 ± 4.3 J/g (LM–M) and 71.5 ± 5.9 J/g (LM–F), which are quite close to the theoretical values.
