Abstract

L'invention concerne un accumulateur hybride de chaleur latente destiné à accumuler de l'énergie thermique provenant de sources thermiques telles que des circuits solaires, des circuits géothermiques, des alimentations en eau chaude, des circuits de réchauffage, des circuits de chaleur de processus et des circuits de chauffage. Un contenant d'accumulateur de chaleur rempli d'un fluide accumulateur de chaleur est doté d'échangeurs thermiques qui sont reliés à l'au moins une des sources de chaleur. L'objectif de l'invention est de créer un accumulateur hybride de chaleur latente présentant, d'une part, les avantages d'un accumulateur de chaleur rempli d'eau, et, d'autre part, les avantages d'un accumulateur de chaleur latente. Cet objectif est atteint en ce que l'on dispose dans le contenant d'accumulateur de chaleur (1) une ou plusieurs cartouches accumulatrices de chaleur (3) remplies d'un deuxième fluide accumulateur de chaleur (4) (matériau à changement de phase), en ce que les cartouches accumulatrices de chaleur (3) sont montées rotatives et sont couplées à une unité d'entraînement (5), et en ce que les cartouches accumulatrices de chaleur (3) sont dotées d'un dispositif destiné à éliminer sur leur surface intérieure le matériau à changement de phase qui est solidifié.
