Parametric studies of thermochemical processes for seasonal storage

Abstract The purpose of this study is the seasonal storage of solar thermal energy for household applications. Thermochemical storage has been adopted with the use of moist air for hydration/dehydration. Various aeraulic processes have been evaluated and compared. Parametric studies enable to have more information concerning the influence of external conditions, component performances and salt characteristics. This study points out that thermochemical storage conception has to be studied has a whole: material, reactor and process. It also provides ways to optimize thermochemical heat storage depending on outdoor conditions and objectives in term of performances.
