Abstract

Die Erfindung betrifft ein System und ein Verfahren zur Durchführung eines hydraulischen Abgleichs in einem Heizungssystem mit wenigstens zwei Heizflächen, wobei der Massenstrom eines Heizfluids durch jede der Heizflächen an jeder der Heizflächen mittels eines elektronischen Thermostatventils individuell durch Einstellung der aktuellen Öffnungsposition des Thermostatventils geregelt wird, wobei für jede der Heizflächen aus Temperaturmesswerten ein den Arbeitspunkt der Heizfläche repräsentierender Wert bestimmt und mit einem gespeicherten Vergleichswert der Heizfläche verglichen wird und in Abhängigkeit des Vergleichs die maximal zulässige Öffnungsposition des Thermostatventil elektronisch begrenzt wird, bei dem in einem Fall, wenn der Vergleich eine hydraulische Überversorgung der Heizfläche anzeigt die aktuelle Öffnungsposition des Thermostatventils um einen Reduktionswert, insbesondere einen festen Reduktionswert, insbesondere mehrfach reduziert wird bis dass der Vergleich ein Ergebnis liefert, gemäß dem eine weitere Reduktion unnötig ist und der Wert der letzten Öffnungsposition als maximal zulässige Öffnungsposition zusammen mit der gemessenen Übertemperatur der Heizfläche zur Bildung und/oder Adaption einer Kennlinie / eines Kennfeldes gespeichert wird.

The invention relates to a system and a method for performing a hydraulic balancing in a heating system with at least two heating surfaces, wherein the mass flow of a heating fluid is controlled by each of the heating surfaces on each of the heating surfaces by means of an electronic thermostatic valve individually by adjusting the current opening position of the thermostatic valve for each of the heating surfaces of temperature readings a value representing the operating point of the heating surface is determined and compared with a stored comparison value of the heating surface and depending on the comparison, the maximum permissible opening position of the thermostatic valve is electronically limited, wherein in a case when the comparison is a hydraulic oversupply the heating surface indicates the current opening position of the thermostatic valve by a reduction value, in particular a fixed reduction value, in particular repeatedly reduced until the Verg Of course, a result is provided according to which a further reduction is unnecessary and the value of the last opening position is stored as the maximum permissible opening position together with the measured excess temperature of the heating surface for the formation and / or adaptation of a characteristic curve / characteristic map.
