Description
Einrichtung zur Regelung der Vorlauftemperatur (bei Warmwasser-Fußbodenheizungen) für kombinierte Fußbodenheizungs- und HeizkörperanlagenDevice for controlling the flow temperature (for hot water underfloor heating) for combined underfloor heating and radiator systems
Die Neuerung betrifft eine Einrichtung gemäß Anspruch 1.The innovation relates to a device according to claim 1.
Es ist bekannt, daß Fußbodenheizungen (im Jahresmittel) mit geringeren Vorlauftemperaturen betrieben werden als Heizkörperanlagen.It is known that underfloor heating systems (on average over the year) are operated with lower flow temperatures than radiator systems.
Bei kombinierten Heizungsanlagen muß ein Niedertemperatur-Heizkreis zur Fußbodenheizung gefuhrt werden. Dies wird, in der Regel, über eine Mischerstation ausgeführt. Die Kosten für die Installation und das Material sind relativ hoch. Alternativ werden, sog. Beimisch-Regelungen eingesetzt, die direkt am Verteiler der Fußbodenheizung montiert werden.In combined heating systems, a low-temperature heating circuit must be connected to the underfloor heating. This is usually done via a mixer station. The costs for installation and materials are relatively high. Alternatively, so-called mixing controls are used, which are mounted directly on the underfloor heating distributor.
Diese Regelungen arbeiten auf dem Prinzip der Zwangsmischung. Es wird das heiße Vorlaufwasser in den Rücklaufbalken des Fußbodenheizungsverteilers gedrückt, eine Pumpe am anderen Ende des Balkens zieht das Wasser aus dem Balken und aus dem Rücklauf der Fußbodenheizung. Dadurch entsteht Mischwasser, was in Vorlaufbalken bzw. in den Vorlauf der Fußbodenheizung gedrückt wird. Am Ende des Vorlauf balkens ist ein Regulierventil installiert, worüber der Differenzdruck eingestellt wird und überschüssiges Wasser in die Heizanlage geführt wird.These controls work on the principle of forced mixing. The hot supply water is pressed into the return bar of the underfloor heating distributor, a pump at the other end of the bar draws the water from the bar and from the return of the underfloor heating. This creates mixed water, which is pressed into the supply bar or into the supply of the underfloor heating. A control valve is installed at the end of the supply bar, which is used to set the differential pressure and to direct excess water into the heating system.
Mit Inkrafttreten der neuen Wärmeschutzverordnung am 01.01.1995 ist der Wärmebedarfgesunken und somit auch die Vorlauftemperaturen in den Heizungsanlagen. Die Differenz der Vorlauftemperaturen ist (im Jahresmittel) kleiner geworden und es kann bei einer Regelung mit Zwangsmischung zu Leistungsproblemen bei der Fußbodenheizung führen.With the entry into force of the new thermal insulation regulation on January 1, 1995, the heat requirement has fallen and with it the flow temperatures in the heating systems. The difference in the flow temperatures has become smaller (on average over the year) and it can lead to performance problems with the underfloor heating when using forced mixing.
Die Neuerung gemäß Anspruch 1 löst dieses Problem, weil eine Rücklauf-Beimischung erst dann zugeschaltet wird, wenn diese erforderlich ist.The innovation according to claim 1 solves this problem because a return flow admixture is only switched on when it is required.
Anhand der Zeichnung wird ein Ausführungsbeispiel dargestellt. Das Beimisch-Regelset wird zwischen Wärmeerzeuger (Heizkessel/Therme) und dem Heizkreisverteiler der Fußbodenheizung direkt vor dem Verteiler installiert.The drawing shows an example of implementation. The mixing control set is installed between the heat generator (boiler/heating system) and the heating circuit distributor of the underfloor heating, directly in front of the distributor.
Das im Wärmeerzeuger erhitzte Wasser (Heizung Vorlauf) wird über dessen Pumpe durch das voll geöffnete Drosselventil (4) in den Vorlaufbalken (7) der Fußbodenheizung gedrückt. Von dort aus wird das Wasser über die Heizkreise in den Rücklaufbalken (8) und in den Rücklauf der Heizung gedrückt. Am Vorlauffühler (3) wird die, nach dem Wärmebedarf ermittelte, maximale Vorlauftemperatur der FußbodenheizungThe water heated in the heat generator (heating flow) is pressed by its pump through the fully open throttle valve (4) into the flow bar (7) of the underfloor heating. From there, the water is pressed via the heating circuits into the return bar (8) and into the return of the heating. The maximum flow temperature of the underfloor heating, determined according to the heat requirement, is measured at the flow sensor (3).
eingestellt. Wird die eingestellte Temperatur überschritten, so schaltet der Vorlauffühler (3) Strom zur Pumpe (2) durch.set. If the set temperature is exceeded, the flow sensor (3) switches power to the pump (2).
Über die Bypaß-Strecke (1) wird jetzt kühleres Rücklaufwasser der Fußbodenheizung über das Vorlaufanschlußstück (9) in den Vorlauf der Fußbodenheizung gepumpt. Durch diese Rücklaufbeimischung wird die Vorlauftemperatur der Fußbodenheizung erheblich reduziert.Cooler return water from the underfloor heating is now pumped via the bypass line (1) into the flow of the underfloor heating via the flow connection piece (9). This return flow mixing significantly reduces the flow temperature of the underfloor heating.
Bei fallendem Wärmebedarf der Fußbodenheizung (durch Fremdwärmequellen, Sonneneinstrahlung etc.) steigt die Rücklauftemperatur der Fußbodenheizung. Um eine Übertemperatur zu vermeiden, wird am Thermostatkopf (5) die maximale Rücklauftemperatur eingestellt. Wenn durch den Rücklauffühler (6) ein Überschreiten der eingestellten Temperatur festgestellt wird, wird über den Thermostatkopf (5) das Drosselventil (4) halb geschlossen. Der Massenstrom im Fußbodenheizungssystem wir somit hydraulisch halbiert. Eine Überhitzung des Systems ist damit ausgeschlossen.If the heat requirement of the underfloor heating falls (due to external heat sources, solar radiation, etc.), the return temperature of the underfloor heating rises. To avoid overheating, the maximum return temperature is set on the thermostat head (5). If the return sensor (6) detects that the set temperature has been exceeded, the throttle valve (4) is half closed via the thermostat head (5). The mass flow in the underfloor heating system is thus halved hydraulically. Overheating of the system is therefore impossible.
Dieses Beimisch-Regelset wird als komplettes Anbauset einschl. steckerfertiger Verdrahtung geliefert und hat die Funktion einer Festwertregelung.This mixing control set is supplied as a complete add-on set including plug-in wiring and has the function of a fixed value control.
In der erweiterten Version 2, gemäß Anspruch 1, wird dem Beimisch-Regelset ein Raumthermostat vorgeschaltet.In the extended version 2, according to claim 1, a room thermostat is connected upstream of the mixing control set.
Dieser Raumthermostat (12) sollte in einem ausgewählten Raum (Pilotraum) des Fußbodenheizungsbereichs installiert werden. Der Raumthermostat (12) ist elektrisch mit dem Vorlaufruhler (3) parallel geschaltet. Wenn die gewünschte Raumtemperatur erreicht ist, schaltet der Raumthermostat Strom zur Pumpe (2) und die o.g. Rücklaufbeimischung beginnt. Diese Pilotraum-Regelung arbeitet unabhängig von der vorgeschriebenen Raumregelung.This room thermostat (12) should be installed in a selected room (pilot room) of the underfloor heating area. The room thermostat (12) is electrically connected in parallel with the flow thermostat (3). When the desired room temperature is reached, the room thermostat switches power to the pump (2) and the return flow mixing mentioned above begins. This pilot room control works independently of the prescribed room control.
In der erweiterten Version 3, gemäß Anspruch 1, wird dem Beimisch-Regelset ein Uhrenthermostat (13) vorgeschaltet.In the extended version 3, according to claim 1, a clock thermostat (13) is connected upstream of the mixing control set.
Pilotraumwahl, elektrische Verdrahtung und Funktionen wie bei Version 2. Zusätzlich besteht die Möglichkeit individuelle Absenkzeiten zu programmieren. Diese Funktion wird bei gewerblicher Nutzung oft gefordert.Pilot room selection, electrical wiring and functions as in version 2. It is also possible to program individual reduction times. This function is often required for commercial use.
Die o.g. Neuerung kann allen handelsüblichen Fußbodenheizungs-Verteilern angepaßt werden.The above innovation can be adapted to all commercially available underfloor heating distributors.
