Abstract

Die Erfindung betrifft ein Verfahren zur Erwärmung von Trinkwasser variablen Volumenstroms nach dem Durchlaufprinzip sowie ein Wassererwärmungssystem. Sie zielt darauf ab, die Auslauftemperatur TW des Wassers auf eine vorgebbare Auslauf-Solltemperatur TW0 zu regeln. Ihr liegt die Aufgabe zugrunde, die Grundlage für eine hohe Ausnutzung des Brennwerteffekts und eine schnelle und präzise Anpassung des Systems auf sich ändernde Wasservolumenströme zu schaffen.The invention relates to a method for heating drinking water variable volume flow according to the flow principle and a water heating system. It aims to regulate the outlet temperature T W of the water to a predefinable outlet setpoint temperature T W0 . Its purpose is to create the basis for a high utilization of the condensing effect and a quick and precise adaptation of the system to changing water volume flows.

Erfindungsgemäß wird bei einer Auslauftemperaturabweichung die Auslauftemperatur mittels einer Veränderung eines modulierbaren und/oder schaltbaren Heizfluidvolumenstroms auf Auslauf-Solltemperatur geregelt. Eine Heizfluidtemperatur TH wird mittels einer Veränderung einer modulierbaren und/oder schaltbaren Wärmeerzeugerwärmeleistung Q auf Heizfluid-Solltemperatur TH0 geregelt.

Figure imgaf001
According to the invention, the outflow temperature is regulated by means of a change of a modulatable and / or switchable Heizfluidvolumenstroms to outlet setpoint temperature at an outlet temperature deviation. A Heizfluidtemperatur T H is controlled by means of a change of a modulatable and / or switchable heat generator heat output Q to heating fluid target temperature T H0 .
