Abstract

Heating aggregates such as heating boilers are usually also used for service-water heating by applying a service-water priority circuit by means of blocking the heating circuit. To avoid too long a switch-off time of the heating circuit, the heating aggregate is, at the beginning of service-water heating, set to full capacity and, as of a predetermined temperature level of the heating water being reached, the heating circuit, in the case of further service-water heating, is opened to such an extent that the heating water temperature does not rise further.

Description

Regelung eines Heizaggregates mit variabler Leistung in Control of a heating unit with variable output in

einer Heizungsanlage Die Erfindung betrifft die Regelung eines Heizaggregates nach dem Oberbegriff des Patentanspruches 1. a heating system The invention relates to the regulation of a heating unit according to the preamble of claim 1.

Während der Braachwassererwärmung dient die zugefuhrte Wärme ausschließlich dem Aufheizen des Brauohwassers. In oberen Temperaturbereichen des Brauchwassers kann dieses das weitere hohe Wärmeangebot nicht mehr schnell genug abnehmen. Das führt zu einem Anstieg a; Temperaturniveaus des Heizwassers und bei einer bestimmten Temperatur zu einem Abschalten des Heizaggregates durch einen benötigten Temperaturwächter, obwohi die gewünschte Brauchwassertemperatur noch nicht erreicht ist. Der Brauchwasserthermostat schaltet das Heizaggregat anschließend wieder ein, was dann nach kurzer Zeit erneut zu einem Abschalten durch den Temperaturwächter führen kann. Ein solches mehrfaches "Takten" verlängert die Blockade des Heizkreises erheblich.During the brown water heating, the supplied heat is used exclusively heating up the brewing water. In the upper temperature ranges of the domestic water this can no longer reduce the further high heat supply quickly enough. That leads to an increase a; Temperature level of the heating water and at a certain Temperature to switch off the heating unit by a required temperature monitor, although the desired hot water temperature has not yet been reached. The domestic hot water thermostat the heating unit then switches on again, which then does so again after a short time can lead to a shutdown by the temperature monitor. Such a multiple "Cycle" extends the blockage of the heating circuit considerably.

Das Problem des "Taktens" bei der Brauchwassererwärmung ist allgemein in der DE-AS 12 99 853 beschrieben. Dort wird zur Lösung des Problems vorgeschlagen, die dem Brauchwasserbereiter zugefUhrte Wärmemenge in oberen Temperaturbereichen durch Drosselung der Leistung des Heizaggregates, speziell durch Drosselung der Brennerleistung, zu zu reduzieren.The problem of "clocking" in domestic water heating is general in DE-AS 12 99 853 described. There it is suggested to solve the problem, the amount of heat supplied to the domestic water heater in the upper temperature ranges by throttling the output of the heating unit, especially by throttling the Burner output to reduce.

Es soll eine schnelle Brauchwasseraufheizung erfolgen, bei der das "Takten" unterbunden und eine zu lange Unterbrechung des Heizens vermieden wird, und zwar ohne die Dekannte Leistungsdrosselung in oberen Temperaturbereichen.A rapid domestic water heating is to take place in which the "Cycle" is prevented and a too long interruption of the heating is avoided, without the decanted power reduction in the upper temperature ranges.

Die Lösung der Erfindung erfolgt durch dle im Kennzeicnen des Patentanspruches 1 genannten ìla.3nah.men, Zu Beginn der 3rauchwassererwärmung wird die Leistung des Heizaggregates voll hochgefahren. Das war bei Heizaggregaten mit den bisherigen auf eine konstant hohe Leistung, jedoch nicht Höchstleistung fest eingestellten Brennern nicht möglich. Die Brauchwassererwärmung erfolgt somit sehr schnell.The invention is solved by the characterizing features of the claim 1 mentioned ìla.3nah.men, At the beginning of the 3 hot water heating the output of the heating unit is fully increased. That was with heating units the previous one on a consistently high performance, but not maximum performance set burners not possible. The domestic water heating is therefore very much fast.

Sobald das festgelegte Temperaturniveau des Heizwassers erreicht ist, wird vom Temperaturwächter bei weiterer Brauchwassererwärmung der Heizkreis soweit geöffnet, da3 die Heizwassertemperatur nicht weiter ansteigt. Diese Schaltung verhindert das "Takten" und verkuerzt die Sperrung des Heizkreises. Diesem wird schon während der letzten Phase der Brauchwassererwärmung wieder Wärme zugeführt. Zudem erhält der Heizkreis nicht erst nach Beendigung der Brauchwassererwärmung eine Wärmezufuhr, die dann mit stark überhöhten Temperaturen anfällt. Es erfolgt eine rechtzeitige Anpassung der Heizwassertemperatur an die niedriger liegende Vorlauftemperatur.As soon as the specified temperature level of the heating water is reached, If the domestic water heating continues, the heating circuit will be increased by the temperature monitor open so that the heating water temperature does not rise any further. This circuit prevents the "pulsing" and shortens the blocking of the heating circuit. This is already during heat is fed back into the last phase of domestic water heating. Also receives the heating circuit does not only supply heat after the domestic water heating has ended, which then occurs with extremely high temperatures. There is a timely Adjustment of the heating water temperature to the lower flow temperature.

Als Heizaggregat kann vorzugsweise ein in Abhängigkeit vom Wärmebedarf durch gleichgerichtete Anpassung der Kesselwassertemperatur und der Brennerleistung an den Wärmebedarf regelbarer Heizungskessel eingesetzt werden, wie er in der Patentanmeldung P 30 27 802.5 beschrieben ist. Hierbei wird zu 3eginn der Brauchwassererwärmung die volle Brennerleistung eingestellt, um die angestrebte, schnelle Brauchwasseraufheizung zu erreichen. Die oeffnung des Heizkreises erfolgt dann bei Erreichen einer festgelegten Kesselwassertemperatur, wodurch das "Takten" wegen der Wärmeabfuhr zum Heizreis verhindert wird.A heating unit can preferably be used as a heating unit, depending on the heat demand by adjusting the boiler water temperature and the burner output in the same direction Heating boilers that can be regulated according to the heat demand can be used, as described in the patent application P 30 27 802.5 is described. Here, the domestic water heating is started the full burner output is set in order to achieve the desired, rapid domestic water heating to reach. The heating circuit is then opened when a specified one is reached Boiler water temperature, which causes "pulsing" because of the heat dissipation to the heating circuit is prevented.

Es ist auch möglich, als Heizaggregat ein anderes Gerät mit variabler Leistung einzusetzen, z.B. eine Wärmepumpe. Auch dieses Gerät soll zu Beginn der Brauchwassererwärmung mit voller Leistung laufen. Sobald das Temperaturnieau ues Heizwassers die festgelegte Höhe hat, erfolgt auch hierbei die oeffnung des Heizkreises.It is also possible to use another device with a variable heating unit To use power, e.g. a heat pump. This device should also be used at the beginning of the Domestic hot water heating run at full capacity. As soon as the temperature level ues Heating water has the specified level, the heating circuit is also opened here.

Die Regelung kann zusätzlich mit der aus der DE-AS 12 99 853 bekannten Drosselung der Leistung ab Erreichen des festgelegten Temperaturniveaus des Heizwassers gekoppelt werden.The scheme can also be used with that known from DE-AS 12 99 853 Throttling of the output once the specified temperature level of the heating water has been reached be coupled.
