Résumé

This article presents a mathematical model for simulation of transient heat and moisture transfer in concrete sandwich panel wall constructions with variable outdoor temperature and humidity as boundary conditions. The objective is to evaluate the possibility of diminishing moisture content in constructions in order to reduce deterioration risks. Some control strategies involving installation of heating cables in the air gap are proposed and investigated. Simulations demonstrate that the moisture condition of the construction can be improved by using the control regulation developed in this paper. This study improves the understanding of the heat and moisture transport properties of concrete sandwich panels and provides useful information on the decision making in solving the construction's moisture problems.
