Abstract

La présente invention porte sur un type de chauffe-eau solaire, et a trait au domaine de la technologie des applications relatives à l'énergie solaire. Le chauffe-eau est constitué d'un collecteur de chaleur solaire et d'une cuve de stockage thermique. Le collecteur de chaleur solaire susmentionné est pourvu d'un orifice de remplissage en liquide, d'un orifice de refoulement et d'une cuve de remplissage-dissipation caractéristique. La cuve de remplissage-dissipation est équipée d'un orifice de remplissage en eau, d'un orifice de remplissage en liquide, d'un orifice de refoulement situé plus haut que l'orifice de remplissage en liquide susmentionné, et d'un orifice de ventilation-débordement au niveau de la partie supérieure. L'orifice de remplissage en eau susmentionné est connecté à la source d'eau avec une unité de commande de liaison, tandis que les orifices de remplissage en liquide et de refoulement susmentionnés sont connectés aux orifices correspondants sur le collecteur de chaleur solaire, formant ainsi une boucle de dissipation circulaire. La présente invention combine de manière intelligente le remplissage et la dissipation afin d'assurer le remplissage en eau et, simultanément, de résoudre le problème de la surchauffe.
