Abstract

L'invention concerne un module d'accumulation d'énergie thermique comprenant une pluralité de panneaux d'accumulation d'énergie thermique espacés, séparés par des ensembles de chauffage. Chaque panneau d'accumulation d'énergie thermique comprend une âme en graphite, un logement sensiblement étanche aux gaz recouvrant l'âme en graphite, et un échangeur thermique comprenant un tubage d'échangeur thermique. Le tubage d'échangeur thermique comprend une entrée d'échangeur thermique et une sortie d'échangeur thermique. Le tubage d'échangeur thermique est au moins partiellement encastré dans l'âme en graphite, l'entrée d'échangeur thermique et la sortie d'échangeur thermique s'étendant à travers le logement. Le logement est scellé autour de l'entrée d'échangeur thermique et de la sortie d'échangeur thermique. Un procédé de commande du module d'accumulation d'énergie thermique comprend : l'établissement d'une connexion électrique entre les ensembles de chauffage et une fourniture d'alimentation électrique permettant aux ensembles de chauffage de chauffer les panneaux d'accumulation d'énergie thermique ; la surveillance d'une température dans l'âme en graphite de chaque panneau d'accumulation d'énergie thermique ; et lorsque n'importe quelle âme en graphite atteint une température supérieure à une limite prédéfinie, la déconnexion de l'alimentation électrique des ensembles de chauffage adjacents au panneau d'accumulation d'énergie thermique donné.
