Abstract

L'invention concerne le domaine du génie énergétique et thermique et notamment le chauffage d'un milieu liquide et peut s'utiliser pour produire de l'eau chaude à des fins ménagères. Le procédé de production d'énergie thermique à partir d'énergie électrique consiste à disposer un élément électrique chauffant dans un environnement constitué d'une substance accumulant la chaleur à l'intérieur d'un espace isolé ; au centre géométrique d'un corps rempli de caloporteur on dispose régulièrement autour de l'élément chauffant un tuyau ayant la forme d'une spirale ascendante dans laquelle on fait circuler un milieu chauffé, et la transmission de chaleur de l'élément chauffant au liquide chauffé s'effectue à travers les parois du tuyau via le caloporteur à l'état solide et remplissant l'espace libre autour de l'élément chauffant et du tuyau destiné à l'écoulement du milieu chauffé ; on utilise en tant que caloporteur un mélange pulvérulent sec. L'invention concerne également un dispositif pour mettre en œuvre ce procédé. Le résultat technique consiste en une baisse de la consommation d'énergie et de puissance spécifique de la source d'énergie thermique grâce à l'utilisation en tant que caloporteur (milieu accumulant la chaleur) d'un mélange sec pulvérulent.
