Description

Thermostatisch geregeltes Heizungsgerät für Sammelheizungsanlagen, insbesondere Umlaufgaswasserheizer Die Erfindung bezieht sich auf ein thermostatisch geregeltes Heizungsgerät für Sammelheizungsanlagen, insbesondere Umlaufgaswasserheizer, mit einem angeschlossenen, über einen Temperaturfühler auf Vorrang schaltbaren Brauchwasserbereiter. Bei Heizungsgeräten dieser Art soll der Brauchwasserbereiter möglichst schnell auf Vorrang geschaltet werden, damit keine großen Temperaturdifferenzen des Brauchwassers eintreten können. Außerdem muß dafür Sorge getragen werden, daß aus Sicherheitsgründen im primären Heizkreislauf eine bestimmte Temperatur nicht überschritten wird. Insbesondere bei Umlaufgaswasserheizern ist es schwierig, diese Forderungen zu erfüllen, da die Stillstandszeiten des Heizungsgerätes groß sind und die Wärmekapazität im Brauchwasserbereiter gering ist.Thermostatically controlled heating device for collective heating systems, in particular circulating gas water heater The invention relates to a thermostatic Regulated heating device for collective heating systems, in particular circulating gas water heaters, with a connected domestic water heater that can be prioritized via a temperature sensor. In heating devices of this type, the water heater should open as quickly as possible Priority can be switched so that there are no large temperature differences in the domestic water can enter. In addition, care must be taken that for safety reasons a certain temperature is not exceeded in the primary heating circuit. In particular with circulating gas water heaters, it is difficult to meet these requirements because the Downtimes of the heating device are large and the heat capacity in the water heater is low.

Bei einer bekannten Anlage wird über einen Differenzdruckschalter bei Brauchwasserentnahme der Brauchwasserbereiter auf Vorrang geschaltet und durch einen Thermostaten die Heizwassertemperatur begrenzt. Durch die vorliegende Erfindung wird das gleiche Ergebnis mit einem einzigen Thermostaten erreicht, indem dieser sowohl vom Brauchwasser als auch vom Heizungsvorlaufwasser beaufschlagt wird.In a known system, a differential pressure switch when the hot water is drawn off, the hot water heater is switched to priority and through a thermostat limits the heating water temperature. Through the present invention the same result is achieved with a single thermostat by using this is acted upon by both the domestic water and the heating flow water.

In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. Es zeigt F i g. 1 einen Temperaturfühler mit einem zweipoligen Thermostaten und schematisch den Brauchwasserbereiter mit Umlaufgaswasserheizer, F i g. 2 die Schaltung über ein Relais.Two exemplary embodiments of the invention are shown in the drawing. It shows F i g. 1 a temperature sensor with a two-pole thermostat and schematically the domestic water heater with circulating gas water heater, F i g. 2 the circuit via a relay.

An den schematisch angedeuteten Umlaufgaswasserheizer 1 mit der Gaszufuhrleitung 2, der Vorlaufleitung 3 und der Rücklaufleitung 4 ist der Brauchwasserbereiter 5 über das Dreiwegeventil 6 angeschlossen. Das bei 7 eintretende Heizwasser durchströmt die Brauchwasserkammer 8 in den Rohren 9 und gelangt anschließend zum Rücklauf 10. In der Mitte des Brauchwasserbereiters 5 ist ein Temperaturfühler 11 so eingebaut, daß er etwa zu zwei Drittel in das Brauchwasser eintaucht und mit dem restlichen Teil vom Heizungsvorlaufwasser beaufschlagt wird. Der Temperaturfühler 11 fühlt das Unterschreiten einer bestimmten Temperatur im Brauchwasserkreis und veranlaßt den zweipoligen Thermostaten, das Dreiwegeventil 6 so zu schalten, daß nur der Brauchwasserbereiter 5 an den Vorlauf 3 angeschlossen ist. Gleichzeitig schaltet er die Umwälzpumpe 12 und den Brenner über das Gasventil 13 ein. Bei Heizungsbetrieb steuert der Kesselwasserthermostat 14 die Pumpe 12 und den Brenner.The water heater 5 is connected via the three-way valve 6 to the schematically indicated circulating gas water heater 1 with the gas supply line 2, the flow line 3 and the return line 4. The heating water entering at 7 flows through the service water chamber 8 in the pipes 9 and then reaches the return line 10. In the middle of the water heater 5, a temperature sensor 11 is installed so that it is about two-thirds immersed in the service water and the remaining part of the heating flow water is applied. The temperature sensor 11 senses that the domestic water circuit has fallen below a certain temperature and causes the two-pole thermostat to switch the three-way valve 6 so that only the domestic water heater 5 is connected to the flow 3. At the same time it switches on the circulation pump 12 and the burner via the gas valve 13 . During heating operation, the boiler water thermostat 14 controls the pump 12 and the burner.

Die Anordnung des Temperaturfühlers 11 ist derart, daß er vom Brauchwasser und vom Heizungswasser beaufschlagt wird. Sie hat verschiedene Vorteile. Übersteigt die Heizwassertemperatur einen oberen Grenzwert (etwa 90° C), dann schaltet er die Anlage ab. Brauchwasserbedarf wird vom selben Temperaturfühler schnell registriert und der Brauchwasserbereiter eingeschaltet. Da beide Funktionen mit ein und demselben Temperaturfühler erreicht werden, ergibt sich eine bedeutende Kostenersparnis durch den Wegfall des Differenzdruckschalters und außerdem eine geringe Störanfälligkeit. Die im Brauchwasserbereiter gespeicherte Wärme vermeidet zu häufige Schaltungen, wenn kein Wasser gezapft wird.The arrangement of the temperature sensor 11 is such that it is from the domestic water and is acted upon by the heating water. It has several advantages. Exceeds the heating water temperature reaches an upper limit value (approx. 90 ° C), then it switches the Plant off. Domestic water demand is quickly registered by the same temperature sensor and the water heater switched on. Since both functions with one and the same Temperature sensor can be achieved, there is a significant cost saving the elimination of the differential pressure switch and also a low susceptibility to failure. The heat stored in the domestic water heater avoids too frequent switching, if no water is drawn.

Das Dreiwegeventil6 kann auch über ein Relais 15 geschaltet werden, wie F i g. 2 zeigt. Bei Unterschreiten einer bestimmten Brauchwassertemperatur schaltet der Temperaturfühler 11 das Dreiwegeventil 6 auf Brauchwasservorrang. Gleichzeitig erhält das Relais 15 Strom, und dadurch wird das Gasventil 13 geöffnet sowie die Pumpe 12 eingeschaltet. Wenn der Brauchwasserbereiter nicht angeschlossen ist, wird über einen Thermostaten 16, beispielsweise einen Raumthermostaten, bei Unterschreiten der eingestellten Temperatur zunächst lediglich die Pumpe eingeschaltet. Der Brenner wird erst dann eingeschaltet, wenn das durch die Pumpe umgewälzte Wasser den Vorlaufthermostaten auf die eingestellte Vorlauftemperatur abgekühlt hat.The three-way valve 6 can also be switched via a relay 15, like F i g. 2 shows. It switches when the hot water temperature falls below a certain level the temperature sensor 11 sets the three-way valve 6 to hot water priority. Simultaneously receives the relay 15 current, and thereby the gas valve 13 is opened as well as the Pump 12 switched on. If the domestic water heater is not connected, will Via a thermostat 16, for example a room thermostat, if the temperature falls below the limit At the set temperature, only the pump is initially switched on. The burner is only switched on when the water circulated by the pump has passed the flow thermostat has cooled down to the set flow temperature.

Außerdem könnte der Brauchwasserbereiter anders aufgebaut oder anders in den Heizkreislauf angeschlossen sein.In addition, the water heater could be constructed differently or differently connected to the heating circuit.
