Abstract

Die vorliegende Erfindung betrifft ein Regelverfahren und einen Regler zur Regelung eines Brenners (2) einer Heizvorrichtung, insbesondere zur Regelung des Brenners eines Brauchwasser-Durchlauferhitzers, wobei der Brenner (2) ein Wärmeträgermedium erwärmt, das an einem Einlauf der Heizvorrichtung eine bestimmte Einlauftemperatur (ϑEin) und an einem Auslauf der Heizvorrichtung eine bestimmte Auslauftemperatur (ϑAus) aufweist, und wobei die Erwärmung des Wärmeträgermediums zumindest in Abhängigkeit einer Solltemperatur (ϑSoll) und der Auslauftemperatur (ϑAus) geregelt wird, wobei das Regelverfahren zunächst ein erstes Maximum (1a) der Auslauftemperatur (ϑAus) bei einer vorbestimmbaren Brennerleistung mißt und anschließend als eine nächste Ausschalttemperatur (SdAus (k+1)) einen Wert zwischen einer maximalen Ausschalttemperatur (SdAusmax) und dem ersten Maximum (1a) der Auslauftemperatur (ϑAus) verwendet. Hierzu wird mit Vorteil eine erste Differenz (Δϑ1) zwischen der maximalen Ausschalttemperatur (SdAusmax) und dem ersten Maximum (1a) der Auslauftemperatur (ϑAus) berechnet. Es ergibt sich somit eine dynamische Ausschaltdifferenz.

The present invention relates to a control method and a controller for regulating a burner (2) of a heating device, in particular for regulating the burner of a process water heater, the burner (2) heating a heat transfer medium which has a certain inlet temperature (ϑ On ) and at an outlet of the heating device has a specific outlet temperature (ϑ off ), and the heating of the heat transfer medium is controlled at least as a function of a set temperature (ϑ set ) and the outlet temperature (ϑ off ), the control method first of all achieving a first maximum ( 1a) measures the outlet temperature (ϑ off ) at a predeterminable burner output and then as a next switch-off temperature (SdAus (k + 1)) a value between a maximum switch-off temperature (SdAus max ) and the first maximum (1a) of the outlet temperature (ϑ off ) used. For this purpose, a first difference (Δϑ 1 ) between the maximum switch-off temperature (SdAus max ) and the first maximum (1a) of the outlet temperature (ϑ Off ) is advantageously calculated. This results in a dynamic switch-off difference.
