Abstract

Procédé de chauffage de liquide dans un réservoir, comportant les étapes suivantes : - fournir au moins un élément chauffant de type PTC, - fournir des moyens de régulation par modulation de largeur d’impulsion, - mesure de paramètres parmi lesquels la température du liquide et la tension appliquée aux bornes de chaque élément chauffants, - chauffage du liquide sans régulation dans la mesure où la température du liquide est inférieure à une première température seuil,- régulation par modulation de largeur d’impulsion de l’alimentation électrique de chaque élément chauffant pour lequel la tension d’alimentation dépasse un seuil prédéterminé dans la mesure où une température mesurée est supérieure à une seconde température seuil déterminée en fonction de paramètres mesurés, - détermination d’un rapport cyclique pour la modulation de l’alimentation électrique de chaque élément chauffant et passage progressif d’un rapport cyclique de 1 au rapport cyclique déterminé[Fig. 3]
