STUDY OF NEW BUILDING MATERIALS WITH HIGH THERMAL DIFFUSIVITY DEVOTED TO HEAT STORAGE
New building materials with high transverse thermal diffusivity have been conceived and proposed. They consist in combinations of materials characterized by differentiated thermal properties, such as bricks or concrete walls in which metallic elements are disposed in the sense of thickness. In the outside walls of buildings, external insulation is required. Heat can be supplied to the walls by radiation or convection. The research is concerned with the study of the thermal behaviour of the proposed structures, by means of theoretical and experimental investigations. A theoretical model and a computer programme have been developed in order to obtain the temperature distribution inside the walls and the amount of stored heat for different geometrical distributions of the conducting elements. Experimental investigations have been carried out on several heat storing walls, charged by solar radiation or by convection, and discharged by convection, makinguse of different materials, and with different distributions of the thermal conductors. Numerical and experimental data have been compared and discussed. Finally, economic and energetic evaluations have been carried out, concerning the proposed structures.
