Procédé de stockage d’énergie solaire thermique par adsorption pour le chauffage des bâtiments : Modélisation et Simulation numérique

摘要

Sorption heat storage systems (SHSS) open new perspectives for solar heating of residential buildings. These systems allow long term heat storage (storage is done in the form of chemical potential) and offer high energy densities (up to 230 kWh/m3 of material on average) compared to conventional heat storage systems such as sensible heat storage (which, for the case of water, has an average energy density of approximately 81 kWh/m3 of material for a temperature change of 70 °C) and latent heat storage (nearly reaching energy densities of 90 kWh/m3 of material on average).This thesis aims to study the performance of a sorption solar heat storage system on zeolite 13X, integrated to low-energy building. Mathematical models of coupled heat and mass transfer of various components of the system are developed and validated through experimentation. Numerical dynamic simulations, as a tool for the design of the SHSS, allow to study its functioning and to establish specific criteria of its feasibility through the results from the parametric sensitivity analysis on its components.
