“…However, for the composite partition wall, it is either in a sensible form, or in sensible and latent form depending on the PCM's fusion temperature, its melting range, its location, and also reposing on the thermal level of the neighboring local. Thus, we have calculated the dimensionless latent heat charged in PCM q Latent PCM and the dimensionless global heat charged in the composite wall q Composite wall in an established periodic regime [15]. These parameters are defined as:…”

The work deals with the thermal behavior of a conventional partition wall incorporating a phase change material (PCM). The wall separates two environments with different thermal properties. The first one is conditioned, while the adjacent space is characterized by a temperature that changes sinusoidally in time. The effect of the PCM is assessed through a comparative analysis of the cases with and without PCM. The performances are evaluated in terms of dimensionless energy stored within the wall, comfort temperature and variations of these quantities as a function of the amount of PCM and its emplacement.
