Abstract

The main objective of this work is to study the essential element of energy storage for an energy storage system intended for under floor heating. For this reason, we have solved numerically the equation of heat that governs this conductive heat exchange. This equation has been discretized by an implicit finite difference method. The algebraic equation thus obtained was solved by the algorithm of Thomas. In addition, we analyzed the influence of different types the building materials, for different thermal concrete conductivities and for different concrete thicknesses on the temperature distribution of the heating slab. The results obtained show that the thermal inertia of the concrete and the choice of construction material have a significant impact on the thermal diffusion in the heating slab.
