Abstract

Die Erfindung betrifft ein Verfahren zur Erwärmung von Wasser variablen Volumenstroms nach dem Durchlaufprinzip sowie ein Wassererwärmungssystem, bei dem ein Wärmeerzeuger ein von einer Pumpe in einem Kreislauf umgewälztes Heizfluid erwärmt, das Heizfluid ein im Durchlauf geführtes Wasser erwärmt, und mindestens ein in einem Wasserweg angeordneter Messfühler eine Auslauftemperatur TW und/oder einen Volumenstrom VW des Wassers misst. Der Erfindung liegt die Aufgabe zugrunde, unter weitgehender Beibehaltung herkömmlicher Komponenten die Taktzeiten bei geringen Wärmeanforderungen zu verlängern und die Abweichungen von der Solltemperatur bei wechselnden Wärmeanforderungen zu verkleinern und damit einen hohen Warmwasserkomfort und eine verbesserte Betriebsweise hinsichtlich der Komponentenlebensdauer zu bieten. Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass die Modulationsbereiche von Pumpe und Wärmeerzeuger sowie die unterschiedlichen thermischen und strömungsmechanischen Trägheiten des Wassererwärmungssystems gezielt in das Temperaturregelverfahren mit einbezogen werden.

Figure imgaf001
The invention relates to a method for heating water of variable volume flow according to the continuous flow principle and a water heating system in which a heat generator heated by a pump in a circulating circulating heated heating fluid, the heating fluid heats a run-in water, and at least one arranged in a waterway sensor an outlet temperature T W and / or a volume flow V W of the water measures. The invention has for its object, while largely retaining conventional components to extend the cycle times with low heat requirements and to reduce the deviations from the target temperature with changing heat requirements and thus to provide a high DHW convenience and improved operation in terms of component life. The inventive method is characterized in that the modulation ranges of pump and heat generator and the different thermal and fluid mechanical inertia of the water heating system are specifically included in the temperature control process.
