Abstract

The depository of phase change material in the macro-capsules utilized for a latent thermal energy storage system considerably improves the thermal performance. Gypsums with improved thermal properties have been obtained using copper tube filled with Hexadecane Phase Change Materials (HPCMs) in order to develop building materials with high thermal energy storage (TES) capacity useful for being applied in high comfort constructive systems.
Firstly, an investigation by means of a differential scanning calorimeter (DSC) was carried out to obtain the latent heat and the transition temperature of HPCMs. Secondly, an additional study was conducted to gauge the improvement of energy storage performance in classical construction material (Gypsum/copper tubes) filled with paraffin developed to improve different properties of PCM and open a wide field of applications to latent heat storage systems. The objective of this research is to use PCM composite as integrated components in a passive solar wall. The proposed composite TROMBE wall allows daily storage of the solar energy in a building envelope and restitution in the evening, with a possible control of the air flux in a ventilated air layer. Experimental investigations of the thermophysical properties of the considered composite (Gypsum/copper tubes) have shown that the material combines a high heat storage potential and an improved heat transfer at the same time. Accordingly, the results showed that the shape-stabilized phase change material prevents the leakage of the molten paraffin during phase transition and proved a good thermal stability.
