Title (EN) METHOD AND APPARATUS FOR REGULATING THE TEMPERATURE OF A HEATING ELEMENT IN A WATER HEATER
(FR) METHODE ET APPAREIL DE REGLAGE DE LA TEMPERATURE D"UN ELEMENT CHAUFFANT DANS UN CHAUFFE-EAU
Abstract: front page image
(EN)In a method and an apparatus for regulating the power which is supplied to a heating element (2) in a water heater (1), preferably a reservoir water heater containing water which is to be heated to a certain temperature, the power which is supplied to the heating element for heating the water, is regulated not only in dependence on the temperature of the water (15), but also in dependence on the temperature of the heating element (2, 4), so that the temperature of the element is kept below a predetermined critical value. The temperature of the heating element is measured directly and/or indirectly, and when the temperature of the element is below the critical value and the temperature of the water in the water heater is below the rated value, maximum power can be supplied to the heating element. When the temperature of the element has reached the critical value, but the temperature of the water in the water heater is still below the rated value, the power is regulated so as to keep the temperature of the heating element below the critical value and to minimize the heating period.
(FR)Dans une methode et un appareil de reglage de la puissance d"alimentation d"un element chauffant (2) dans un chauffe-eau (1), de preference un chauffe-eau a reservoir contenant de l"eau qui doit etre chauffee a une certaine temperature, la puissance d"alimentation de l"element chauffant pour chauffer l"eau est reglee non seulement en fonction de la temperature de l"eau (15), mais egalement en fonction de la temperature de l"element (2, 4), de sorte que la temperature de l"element est maintenue en dessous d"une valeur critique predeterminee. La temperature de l"element chauffant est mesuree directement et/ou indirectement, et lorsque la temperature de l"element se trouve en dessous de la valeur critique et la temperature de l"eau dans le chauffe-eau se trouve en dessous de la valeur prevue, la puissance maximum peut etre fournie a l"element chauffant. Lorsque la temperature de l"ele a atteint la valeur critique, mais la temperature de l"eau dans le chauffe-eau se trouve encore en dessous de la valeur prevue, la puissance est reglee de maniere a maintenir la temperature de l"element chauffant en dessous de la valeur critique et de maniere a reduire au minimum la periode de chauffage.
