Schichtladespeicher, wie sie beispielsweise aus
Für eine optimale
Funktion des Schichtladespeichers ist dabei auch während der
Warmwasserentnahme und des Nachladens eine stabile Temperaturschichtung
erforderlich. Aus der

Aus
der
Eine Regeleinrichtung für den Ladevorgang befindet sich üblicherweise in der Regelung des Wärmeerzeugers oder der Betrieb des Schichtladespeichers erfolgt völlig autark und unabhängig vom Zustand und von der Art des Wärmeerzeugers. Je nach Anlagenkonfiguration, d. h. je nach Auswahl von Schichtladespeicherbauart und -größe, eingesetzter Ladepumpe sowie je nach Leistungscharakteristik des Wärmeerzeugers, müssten speziell angepasste Regeleinrichtungen geschaffen werden, um ein optimales Zusammenspiel der erwähnten Systemkomponenten zu erreichen. Dies erscheint aus fertigungstechnischer und logistischer Sicht unwirtschaftlich. Außerdem würde dies einen hohen Konfigurationsaufwand bei der Installation vor Ort erfordern und ist daher eventuell fehleranfällig. Andererseits wird aber möglicherweise Energieeinsparungspotenzial in einem Heizsystem sowie Komfortpotenzial für die betreffenden Anlagennutzer verschenkt, wenn Schichtladespeicher und Wärmeerzeuger nicht optimal aufeinander abgestimmt sind.A Control device for the charging process is usually located in the regulation of the heat generator or the operation of the stratified storage system is completely self-sufficient and independent on the condition and type of heat generator. Depending on the system configuration, d. H. depending on the choice of Schichtladespeicherbauart and size, used charge pump and depending on the performance characteristics of the heat generator, would have special adapted control devices are created to be optimal Interplay of the mentioned To achieve system components. This appears from production engineering and logistical point of view uneconomical. In addition, this would require a lot of configuration require on-site installation and may therefore be prone to error. on the other hand but may be Energy saving potential in a heating system as well as comfort potential for the given to plant users concerned, if stratified storage and heat generator not optimally matched.
Der Erfindung liegt die Aufgabe zu Grunde, die Warmwasserbereitung mit einem Wärmeerzeuger und einem Schichtladespeicher zu optimieren.Of the Invention is based on the object, the hot water with a heat generator and to optimize a stratified storage.
Erfindungsgemäß wird dies mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.According to the invention this is solved with the features of claim 1. Advantageous developments are the dependent claims refer to.
Das Verfahren zur Warmwasserbereitung mit einem Wärmeerzeuger und einem Schichtladespeicher ist dadurch gekennzeichnet, dass die Regeleinrichtung für den Ladevorgang dem Schichtladespeicher zugeordnet ist und sich automatisch auf die Anlagensituation einstellt. Dadurch wird die Warmwasserbereitung im Zusammenhang mit dem zugeordneten Wärmeerzeuger optimiert und auf diesen abgestimmt.The Process for hot water preparation with a heat generator and a stratified storage tank is characterized in that the regulating device for the charging process is associated with the stratified storage and automatically on adjusts the investment situation. This will make the hot water optimized in connection with the associated heat generator and on coordinated.
Eine erste Funktion ist zur Identifikation der Funktionalität und/oder der Leistungscharakteristik des angeschlossenen Wärmeerzeugers vorgesehen. Diese wird auf Anforderung und/oder in Abhängigkeit von Betriebssituationen aktiviert. Dabei wird der Lademassenstrom von Null auf einen Grenzwert gesteigert und die Temperatur des aus dem Wärmeerzeuger austretenden Wassermassenstromes wird erfasst. Insbesondere der Temperaturanstieg pro Zeiteinheit wird ermittelt und in einem Funktionsspeicher hinterlegt, so dass sich gute Aussagen über Funktionalität und/oder Leistungscharakteristik des Wärmeerzeugers machen lassen. Vorzugsweise wird diese erste Funktion bei Inbetriebnahme des Schichtladespeicher-Systems und/oder nach Unterbrechung der Stromversorgung aktiviert.A first function is provided for identifying the functionality and / or the performance characteristics of the connected heat generator. This is activated on request and / or depending on operating situations. The charge mass flow is increased from zero to a limit value and the temperature of the water mass flow emerging from the heat generator is detected. In particular, the temperature rise per unit time is determined and stored in a function memory, so that good statements about functionality and / or performance of the heat let make a mariner. Preferably, this first function is activated at startup of the stratified charge storage system and / or after interruption of the power supply.
Eine zweite Funktion dient zum Abruf der maximalen Wärmeerzeuger-Leistung und ist während der Warmwasserbereitung, also bei eingeschalteter Ladepumpe, aktivierbar. Dabei wird der Lademassenstrom von einem Ausgangswert mit einer festgelegten Geschwindigkeit angehoben und die Temperatur des aus dem Wärmeerzeuger austretenden Wassermassenstromes erfasst. Wenn bei zunehmendem Massenstrom die Temperatur des aus dem Wärmeerzeuger austretenden Wassermassenstromes steigt, wird der Wassermassenstrom weiter angehoben. Dagegen wird der Massenstrom reduziert, wenn die Temperatur des aus dem Wärmeerzeuger austretenden Wassermassenstromes fällt. In diesem Fall war die Leistungsgrenze des Wärmeerzeugers überschrittenA second function is to retrieve the maximum heat generator power and is while the hot water, that is activated when the charge pump is switched on. The charge mass flow is from an initial value with a specified Speed raised and the temperature of the heat generator detected leaking water mass flow. When increasing mass flow the temperature of the heat generator escaping water mass flow increases, the water mass flow further raised. In contrast, the mass flow is reduced when the Temperature of the heat generator escaping water mass flow drops. In this case was the Power limit of the heat generator exceeded
Eine dritte Funktion beinhaltet die Regellogik des Schichtladesystems beim Ladevorgang, Mit dieser Funktion wird insbesondere der Betrieb der Ladepumpe geregelt, wobei damit bestimmt ist, welche Temperaturfühler mit welchen Vorgabewerten auf den Betrieb der Ladepumpe Einfluss haben. Generell kann der Wassermassenstrom beim Ladevorgang durch Regeln der Leistung der Ladepumpe variiert werden. Alternativ dazu ist dies auch mit einer Bypassregelung möglich, wobei in einer die Ladepumpe umgehenden Bypassleitung ein elektronisch geregeltes Ventil angeordnet ist.A third function includes the rule logic of the stratified charge system during charging, this function is in particular the operation regulated by the charge pump, whereby it is determined which temperature sensor with which default values influence the operation of the charge pump. In general, the water mass flow during charging by rules the performance of the charge pump can be varied. Alternatively, it is this is also possible with a bypass control, in which the charge pump bypassing Bypass line an electronically controlled valve is arranged.
