Abstract
Description
Die Erfindung betrifft einen Warmwasserbereiter nach dem Oberbegriff des Patentanspruches 1.The invention relates to a water heater according to the preamble of
Ein gattungsgemäßer Warmwasserbereiter ist beispielsweise aus der
Üblicherweise ist ein solcher Wärmetauscher an einen Schichtenspeicher zur Pufferung angeschlossen. Dabei ist es wesentlich, dass die Schichtung im Speicher bei der Bereitung des Warmwassers möglichst wenig gestört wird.Usually, such a heat exchanger is connected to a stratified storage tank for buffering. It is essential that the stratification in the memory during the preparation of the hot water is disturbed as little as possible.
Dennoch ergibt sich bei den bekannten Warmwasserbereitern das Problem, dass bei kleinen Warmwasser-Zapfmengen aufgrund einer konstant gehaltenen Pumpenleistung im Heizwasserkreislauf das dem Primärkreis des Wärmetauschers zugeführte Heizwasser nicht tief genug abgekühlt werden kann und dadurch die Schichtung im Pufferspeicher zerstört wird. Bei minimalen Zapfmengen wird die Temperatur des Heizwasserrücklaufs nur minimal unter der gewünschten Brauchwasser-Temperatur liegen, weil das Heizwasser auch nur gering abgekühlt wird. Eine niedrige Temperatur des Rücklaufs zu einem Pufferspeicher ist bei dieser Bauart also nur bei Volllast gewährleistet, in allen Teillastfällen steigt die Temperatur des Rücklaufs zum Speicher bis maximal zur Warmwasseraustrittstemperatur an, wodurch die Schichtung im Speicher gestört wird und der Gesamtwirkungsgrad der Anlage sinkt. Eine optimale Brennwert- oder Solarenergienutzung ist dann nicht möglich.Nevertheless, results in the known water heaters, the problem that at small hot water taps due to a constant pump performance in Heizwasserkreislauf the primary circuit of the heat exchanger supplied heating water can not be cooled low enough and thus the stratification is destroyed in the buffer memory. With minimum dispensing volumes, the temperature of the Heizwasserrücklaufs only minimally below the desired hot water temperature, because the heating water is cooled even slightly. A low temperature of the return to a buffer memory is thus guaranteed only at full load in this type, in all part load cases, the temperature of the return to the storage rises to a maximum of hot water outlet temperature, whereby the stratification is disturbed in memory and the overall efficiency of the system decreases. An optimal use of condensing or solar energy is then not possible.
Aus der
Trotz dieser Maßnahmen können in der Warmwasser-Ablaufleitung aber stark schwankende Warmwassertemperaturen auftreten, welche unkomfortabel sind.Despite these measures, however, strongly fluctuating hot water temperatures can occur in the hot water drain line, which are uncomfortable.
Der Erfindung liegt daher die Aufgabe zu Grunde, insbesondere in Verbindung mit einem Pufferspeicher die Warmwasserbereitung über einen Wärmetauscher zu optimieren.The invention is therefore based on the object, in particular in conjunction with a buffer memory to optimize the hot water preparation via a heat exchanger.
Erfindungsgemäß wird dies mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.This is achieved with the features of
Der Warmwasserbereiter ist dadurch gekennzeichnet, dass in der Warmwasser-Ablaufleitung ein Warmwassermischer angeordnet ist, dessen Anschluss mit einer Quelle von Wasser verbunden ist, dessen Temperatur unter jener der Warmwasser-Ablaufleitung liegt, und dass der Sekundärkreis mit mindestens einem Zwischenanschluss versehen ist, welcher als Quelle von Wasser dient, dessen Temperatur unter jener der Warmwasser-Ablaufleitung liegt.The water heater is characterized in that in the hot water drain line, a hot water mixer is arranged, whose connection is connected to a source of water whose temperature is lower than that of the hot water drain line, and that the secondary circuit is provided with at least one intermediate connection, which Source of water is used, whose temperature is lower than that of the hot water drain line.
Damit wird der Sekundärkreis des Wärmetauschers unterbrochen, so dass der gesamte Volumenstrom des Kaltwassers zunächst im ersten, unteren Teil des Wärmetauschers vorgewärmt wird und erst dann zur Mischung am Warmwassermischer zur Verfügung steht. Dadurch wird die Stellgüte optimiert und parallel dazu wird der Wärmetauscher lastabhängig betrieben, weil der Warmwasser-Volumenstrom im oberen Teil des Wärmetauschers variiert. Es ergeben sich geringere Auswirkungen auf die Warmwassertemperatur am Auslauf durch die Trägheit des Wärmetauschers, da dem Wärmetauscher Volumenstromanteile entzogen werden.Thus, the secondary circuit of the heat exchanger is interrupted, so that the entire volume flow of the cold water is first preheated in the first, lower part of the heat exchanger and only then is available for mixing the hot water mixer. As a result, the control quality is optimized and parallel to the heat exchanger is operated load-dependent, because the hot water flow rate in the upper part of the heat exchanger varies. There are less effects on the hot water temperature at the outlet due to the inertia of the heat exchanger, as the heat exchanger volume flow components are withdrawn.
In einer ersten Ausführungsform ist ein Wärmetauscher mit mindestens einem Zwischenanschluss im Sekundärkreis an diesem Wärmetauscher vorgesehen.In a first embodiment, a heat exchanger with at least one intermediate connection in the secondary circuit is provided on this heat exchanger.
Die gleiche Funktion kann auch mit einer zweiten Ausführungsform erreicht werden, indem mindestens zwei Wärmetauscher in Reihe geschaltet werden. Dabei wird der mindestens eine Zwischenanschluss im Primärkreis und/oder der mindestens eine Zwischenanschluss im Sekundärkreis zwischen den beiden Wärmetauschern abgegriffen. Beispielsweise an einer Verbindungsleitung oder an einem Formstück zum Verbinden der beiden Wärmetauscher.The same function can also be achieved with a second embodiment by connecting at least two heat exchangers in series. In this case, the at least one intermediate connection in the primary circuit and / or the at least one intermediate connection tapped in the secondary circuit between the two heat exchangers. For example, on a connecting line or on a fitting for connecting the two heat exchangers.
An den Zwischenanschluss im Sekundärkreis kann auch eine Zirkulationsleitung mit eigener Zirkulationspumpe angeschlossen sein, welche dann auch als Quelle von Wasser für den sekundärseitigen Warmwassermischer dient, dessen Temperatur unter jener in der Warmwasser-Ablaufleitung liegt. Vorteilhaft daran ist, das bei vorliegender Zirkulation, also einem Teillastfall, nur einen Teil des Wärmeübertragers genutzt wird.To the intermediate port in the secondary circuit can also be connected to a circulation line with its own circulation pump, which then serves as a source of water for the secondary-side hot water mixer whose temperature is lower than that in the hot water drain line. The advantage of this is that in the present circulation, so a partial load case, only a portion of the heat exchanger is used.
Weiterhin kann das Mischventil im Primärkreis des Wärmetauschers mit dem Warmwassermischer im Sekundärkreis gekoppelt und mit einer gemeinsamen Einstellvorrichtung versehen sein, welche zum Beispiel zentral angeordnet ist und beidseitig wirkt. Mit der gemeinsamen Einstellvorrichtung für beide Mischventile ist sichergestellt, dass im jeweiligen Mischpunkt am primärseitigen Mischventil immer eine etwa 5 Kelvin bis 10 Kelvin höhere Wassertemperatur als am Warmwassermischer im Sekundärkreis eingestellt wird. Vorteil dieser kombinierten Anordnung von beiden Mischventilen wäre, dass eine Begrenzung der primärseitigen Einlauftemperatur in den Wärmetauscher einer Verkalkung vorgebeugt und dass für den Bediener der Einstellvorrichtung nur ein Einstellpunkt existiert.Furthermore, the mixing valve in the primary circuit of the heat exchanger can be coupled to the hot water mixer in the secondary circuit and be provided with a common adjusting device, which is arranged centrally, for example, and acts on both sides. With the common setting device for both mixing valves it is ensured that in the respective mixing point on the primary-side mixing valve always a water temperature which is about 5 Kelvin to 10 Kelvin higher is set than at the hot water mixer in the secondary circuit. Advantage of this combined arrangement of both mixing valves would be that a limitation of the primary-side inlet temperature in the heat exchanger prevents calcification and that there is only one set point for the operator of the adjustment.
Mit der Erfindung wird insbesondere in Verbindung mit einem Pufferspeicher die Warmwasserbereitung über einen Wärmetauscher optimiert. Für den Nutzer ergibt sich der Vorteil, dass bei einer Zapfung das Temperaturniveau des Warmwassers sehr gleichmäßig bleibt. Es wird insbesondere bei kleinen Zapfungen die Rücklauftemperatur auf der Primärseite reduziert, da im Gegensatz zu anderen bekannten Anordnungen nun ein maximaler Volumenstrom im unteren Teil eines Wärmetauschers bzw. im zweiten Wärmetauscher zur Verfügung steht. Bei bekannten Anordnungen wäre der Volumenstrom in diesem Bereich auf der Primärseite reduziert. Dadurch liegt immer die für den aktuellen Betriebszustand niedrigste Rücklauftemperatur am Rücklaufanschluss eines primärseitig angeschlossenen Speichers an, so dass eine Optimierung des Gesamtsystems erreicht werden kann, beispielsweise weil die Schichtung im Speicher erhalten bleibt oder weil Solarwärme auf einem niedrigen Temperaturniveau im unteren Bereich des Speichers übertragen werden kann.With the invention, in particular in conjunction with a buffer memory, the hot water preparation is optimized via a heat exchanger. For the user, there is the advantage that with a tap, the temperature level of the hot water remains very even. In particular with small taps, the return temperature on the primary side is reduced since, in contrast to other known arrangements, a maximum volume flow is now available in the lower part of a heat exchanger or in the second heat exchanger. In known arrangements, the volume flow in this area would be reduced on the primary side. As a result, the lowest return temperature for the current operating state is always applied to the return connection of a primary-side connected memory so that optimization of the overall system can be achieved, for example because the stratification in the memory is retained or because solar heat is transferred to a low temperature level in the lower region of the memory can.
