Abstract

La présente invention concerne un système de chauffage muni d'un élément chauffant à régulation automatique, la température pouvant être régulée avec précision à l'intérieur d'une plage de température donnée et être maintenue uniformément par l'élément chauffant à régulation automatique qui peut temporairement réguler automatiquement l'énergie et la température ; la consommation d'énergie peut être nettement réduite du fait que la température de l'eau peut être maintenue avec une alimentation minimale en énergie une fois que l'eau a chauffé au-delà d'un point d'ébullition fixé. Le système de chauffage comprend : un caisson muni d'une entrée d'air et d'une sortie d'air par lesquelles l'air extérieur entre et sort respectivement ; un élément chauffant à régulation automatique (élément chauffant SR) qui est agencé à l'intérieur du caisson, est formé d'un mélange pâteux durci d'un matériau à résistance électrique, d'un liant isolant et d'un matériau de thermorégulation, génère de la chaleur avec l'énergie qui lui est fournie, et régule automatiquement la température de sorte qu'elle est maintenue uniformément à l'intérieur d'une plage définie ; un dispositif de commande qui commande la température de la chaleur générée en commandant l'énergie appliquée à l'élément chauffant SR ; et un moyen de décharge qui est agencé à proximité de l'élément chauffant SR pour aspirer l'air par l'entrée d'air et, après avoir mis l'air aspiré en contact avec l'élément chauffant SR, décharger l'air chauffé par la sortie d'air.
