Vers un usage du Xylitol surfondu pour le stockage d’énergie thermique saisonnier

This work aims at finding ways to overcome the difficulties related to the energy discharge of a seasonal storage system integrating undercooled xylitol for building applications (problem of activation and insufficient powers).Stirring by bubbling is a simple, low intrusive, low cost and hence a promising technique to activate and accelerate the energy discharge. It allows discharginga 16,1 dm3container with an undercooled xylitol column of 18 cmat a temperature close to ambient onein less than one hour.
