The objective of this work is to study the heat flux transmitted through a partition wall with and without phase change materials from a local of sinusoidal temperature evolution to another conditioned. The aim is in fact the selection of a suitable PCM to be inserted in partition wall constituted only by concrete. A numerical method based on implicit scheme is developed in view to compare two partition walls subjected to the same thermal conditions. The first wall is constituted only by concrete while the second is characterized by a PCM layer inserted in concrete medium. A monodimensional numerical model validated analytically, is used to carry out a parametric analyzes to determine the effect of phase change material in the partition wall. Numerical calculations are performed for three phase change materials with variable thickness according to thermal level of sinusoidal temperature. The results show that the insertion of phase change materials in partition wall can provide the best saving of energy consumption, regardless the temperature fluctuations.
