Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Betreiben mehrerer Durchlauferhitzer mit einer Gesamtmaximalleistung, welche die Maximalleistung des Haus- oder Anlagenanschlusses übersteigt.The The invention relates to a method for operating multiple Instantaneous water heater with a total maximum power, which is the maximum power of the House or system connection exceeds.
Elektrische Durchlauferhitzer benötigen im Vergleich zu anderen Haushaltsgeräten viel elektrische Leistung. Demnach können Haus- oder Anlagenanschlüsse überfordert sein, wenn mehrere elektrische Durchlauferhitzer gleichzeitig betrieben werden sollen. Überfordern mehrere parallel betriebene elektrische Durchlauferhitzer gemäß dem Stand der Technik einen Haus- oder Anlagenanschluss, so bricht zunächst die Spannung ein. Dies hat zur Folge, dass alle Durchlauferhitzer nur noch Wasser mit einer reduzierten Temperatur liefern können. Bei starker Überlastung wird die Sicherung ausgelöst, so dass überhaupt kein Wasser mehr erhitzt wird.electrical Instantaneous water heater need much electrical power compared to other household appliances. Accordingly, you can House or plant connections overwhelmed be when multiple electric water heater operated simultaneously should be. overtax several parallel operated electric water heater according to the state the technology of a house or plant connection, so first breaks the Tension. As a result, all water heaters only can still deliver water at a reduced temperature. at heavy overload the fuse is triggered so that at all no more water is heated.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zum Betreiben mehrerer Durchlauferhitzer zu schaffen, welches es ermöglicht, auch dann mehrere Durchlauferhitzer zu betreiben, wenn deren angeforderte Leistung die Maximalleistung des Haus- oder Anlagenanschlusses übersteigt.Of the The invention is therefore based on the object, a method for operating to provide multiple water heaters, which makes it possible even then to operate multiple water heaters, if requested Power exceeds the maximum power of the house or system connection.
Erfindungsgemäß wird dies gemäß den Merkmalen des unabhängigen Anspruchs 1 dadurch gelöst, dass in dem Fall, in dem die Gesamtsollleistung mehrerer elektrischer Durchlauferhitzer die Maximalleistung des Haus- oder Anlagenanschlusses übersteigt, allen oder nur einem Teil der Leistung anfordernden Durchlauferhitzer nur eine reduzierte elektrische Leistung freigegeben wird. Hierdurch wird eine Überlastung des Systems verhindert. Die Merkmale der abhängigen Ansprüche schützen vorteilhafte Ausgestaltungen dieser Leistungsreduktion.According to the invention this is according to the characteristics of the independent Claim 1 solved by that in the case where the total rated power of a plurality of electric Instantaneous water heater exceeds the maximum output of the house or plant connection, all or part of the power requesting water heater only a reduced electrical power is released. hereby becomes an overload of the system prevented. The features of the dependent claims protect advantageous Embodiments of this power reduction.
So kann einerseits die Solltemperatur aller oder eines Teils der Leistung anfordernden Durchlauferhitzer temporär reduziert werden. Hierzu sind Grenzen der Temperaturreduktion sinnvoll. Des Weiteren ist es möglich, den Durchfluss durch einen oder mehrere Durchlauferhitzer temporär zu reduzieren und dadurch das Temperaturniveau zu halten. Erfindungsgemäß kann sowohl die Temperatur als auch der Durchfluss reduziert werden. Die Regelung erfolgt, indem Informationen über die Betriebsparameter der Durchlauferhitzer an eine übergeordnete Regelung weitergeleitet werden. Dies kann über elektrische Datenleitungen, Modulation auf der elektrischen Anschlussleitung oder über Funk (z.B. 466 MHz, Bluetooth) erfolgen.So On the one hand, the setpoint temperature of all or part of the power requesting instantaneous water heater can be temporarily reduced. For this Limits of temperature reduction make sense. Furthermore is it is possible temporarily reduce the flow through one or more instantaneous water heaters and thereby keeping the temperature level. According to the invention, both the temperature as well as the flow are reduced. The regulation is done by adding information about the operating parameters of the water heater to a parent Regulation will be forwarded. This can be done via electrical data lines, Modulation on the electrical connection cable or via radio (e.g., 466 MHz, Bluetooth).
In einer vorteilhaften Ausgestaltung der Erfindung können einzelne Durchlauferhitzer bevorzugt behandelt werden. Dies bedeutet, dass zunächst den anderen Durchlauferhitzern zugeteilte Leistung entzogen wird, sodass der oder die bevorzugten Durchlauferhitzer weiterhin den vollen Komfort liefern können. Jedem Durchlauferhitzer kann individuell vorgegeben werden, ob seine Leistungsreduktion zunächst eine Reduzierung der Durchflussmenge oder der Temperatur vorsieht sowie wieweit diese Parameter reduziert werden dürfen. Reicht die Reduzierung auf die Wunschminimalleistungen nicht aus, so muss die Regelung, wenn zu viele Durchlauferhitzer gleichzeitig betrieben werden sollen, den einzelnen Durchlauferhitzern Leistungen unterhalb der Wunschparameter zur Einhaltung eines Mindestkomforts zuweisen.In an advantageous embodiment of the invention can individual Flow heaters are preferably treated. This means that first the power allocated to the other water heaters is withdrawn, so that the preferred water heater or continue to the can provide full comfort. Each water heater can be specified individually, whether his Power reduction first a reduction of the flow rate or the temperature provides and how far these parameters can be reduced. Is enough the reduction on the desired minimum benefits, the scheme, if too many water heaters are to be operated simultaneously, the individual water heaters services below the desired parameters to ensure minimum comfort.
Die Erfindung wird nun anhand der Figur detailliert erläutert.The Invention will now be explained in detail with reference to FIG.
Die
Figur zeigt drei Durchlauferhitzer
Jeder
Durchlauferhitzer
Die
Gesamtsollleistung der Durchlauferhitzer PSoll,ges beträgt nach
folgender Formel
Es
wird davon ausgegangen, dass alle drei Durchlauferhitzer
Nun
wird zusätzlich
zu den Durchlauferhitzern
Ziel des erfindungsgemäßen Verfahrens ist daher nun, bei jedem elektrischen Durchlauferhitzer die Leistung derart einzuschränken, dass für die individuelle Zapfstelle die Leistungseinbuße wenig beeinträchtigt wird.aim the method according to the invention is therefore now, with any electric water heater performance to restrict that that for the individual tapping point the performance loss is little affected.
Die
Reduktion an den einzelnen Geräten kann
nun für
alle Geräte
unter gleichem Betrag erfolgen, sie kann jedoch auch prozentual
erfolgen. In einer vorteilhaften Ausgestaltung ist vorgesehen, dass einzelne
Geräte
mehr von der Leistungseinschränkung
betroffen sind als andere. Im folgenden Fall wird davon ausgegangen,
dass die zugeteilte Leistung jeweils gleichmäßig den Durchlauferhitzern
vorenthalten wird. Die Gesamtsollleistung Pmax,ges beträgt im vorliegenden
Fall 33,4 kW. Die Maximalleistung Pmax,Anschluss des
Haus- oder Anlagenanschlusses
Wären größere Leistungsreduktionen
notwendig, so wäre
es nicht sinnvoll, die Auslauftemperatur der Durchlauferhitzer
An
den Regelungen
Sind diese Vorgaben jedoch so hoch, dass die Maximalleistung Pmax,Anschluss des Haus- oder Anlagenanschlusses immer noch überschritten würde, so wird auch diese Vorgabe unterschritten.However, if these specifications are so high that the maximum power P max, connection of the house or system connection would still be exceeded, this requirement is also undershot.
Wichtig beim erfindungsgemäßen Regelverfahren ist stets, dass zunächst überprüft wird, ob die Anschlussleistung bei den Vorgaben überschritten würde und erst dann Teilleistungen freigegeben werden, die in der Summe maximal der Maximalleistung Pmax,Anschluss entsprechen und nicht umgekehrt erst eine Leistung eingestellt wird, die anschließend heruntergeregelt werden muss.Important in the control method according to the invention is always that is first checked whether the connection power would be exceeded in the specifications and only then partial services are released, which correspond in the sum of maximum maximum power P max, connection and not vice versa until a power is set, then must be regulated down.
Nicht
dargestellt, aber auch erfindungsgemäß vorstellbar ist, dass die

eine externe Regelung, die sich nicht in den Durchlauferhitzern
