Description

Die Erfindung betrifft eine Steuervorrichtung für Heizregister von Warmwasserzentralheizungsanlagen mit zwei getrennten, hintereinander parallel auf einer in einer Wandnische an der Wand befestigten Rahmen wahlweise aufsteckbaren, länglichen Mehrfachverteiler mit paarweise in einer Reihe angeordneten Rohranschlüssen für den jeweiligen Heizwasservor- und -rücklauf von Heizregistern-und mit teilweise durch Raumthermostate gesteuerten Stellventilen im jeweiligen Heizwasservorlauf- und -rücklauf.The invention relates to a control device for heating registers of hot water central heating systems with two separate, one after the other in a wall niche on the frame optionally attached, elongated multiple manifold with pairs arranged in a row pipe connections for the respective heating water supply and return of heating registers and with control valves in the respective heating water supply and return, partly controlled by room thermostats.

Es sind bereits verschiedene Steuervorrichtungen für derartige Heizregister bekannt, bei denen die elektrische Verkabelung zwischen den in den Wohnräumen angeordneten Thermostaten und den zugehörigen Stellantrieben vom Installateur verlegt wird, deren Montage und elektrische Installation nicht völlig befriedigt haben.Various control devices for such heating registers are already known, in which the electrical wiring between the thermostats arranged in the living rooms and the associated actuators is installed by the installer, whose assembly and electrical installation have not been completely satisfied.

Die Erfindung hat sich zur Aufgabe gestellt, eine neuartige Bauweise einer derartigen Steuervorrichtung für Heizregister, insbesondere zum Einsatz bei Fußbodenheizungen anzugeben, die durch einfache konstruktive Maßnahmen durch weniger qualifiziertes Personal leichter installiert werden kann.The object of the invention is to provide a novel construction of such a control device for heating registers, Specify particularly for use in underfloor heating, which can be installed more easily by simple construction measures by less qualified personnel.

.Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß eine zentrale Steuervorrichtung in einem länglichen Gehäuse im wesentlichen parallel auf der von den Rohranschlüssen entfernt liegenden Seite der beiden Mehrfachverteiler angeordnet ist, daß die zentrale Steuervorrichtung einen Transformator zur Erzeugung einer Niederspannung aufweist, die über separate Koppelglieder den einzelnen Raumthermostaten und über erste Steckdosen dem Stellantriebsmotor für das jeweils thermostatisch zu steuernde Stellventil.zugeführt wird, daß die Koppelglieder in der gleichen Reihenfolge angeordnet sind wie die Rohranschlüsse der vom zugeordneten Raumthermostat geregelten Heizregister. und daß die ersten Steckdosen in der gleichen Reihenfolge angeordnet sind wie die Rohranschlüsse der vom zugeordneten Raumthermostat geregelten Heizregister.This object is achieved according to the invention in that a central control device is arranged in an elongated housing substantially parallel on the side of the two multiple distributors which is remote from the pipe connections, in that the central control device has a transformer for generating a low voltage, which has separate Coupling links to the individual room thermostats and the first actuator to the actuator motor for the thermostatically controlled control valve. The coupling links are arranged in the same order as the pipe connections of the heating register controlled by the assigned room thermostat. and that the first sockets are arranged in the same order as the pipe connections of the heating register controlled by the associated room thermostat.

Hierbei wird erreicht, daß die Verkabelungen zwischen zentraler Steuervorrichtung und Raumthermostaten und vom Raumthermostaten zu den Stellantriebsmotoren der jeweils thermostatisch zu steuernden Stellventile für die einzelnen Heizregister auch von einem vom zuständigen Elektrizitätswerk nicht lizenzierten Fachmann,d.h.auch von dem Heizungsmonteuer, installiert und angeschlossen werden kann.What is achieved here is that the cabling between the central control device and room thermostats and from the room thermostat to the actuator motors of the thermostatically controlled control valves for the individual heating registers can also be installed and connected by a specialist who is not licensed by the responsible electricity company, i.e. also by the heating engineer.

Bei einer bevorzugten Ausführungsform ist es günstig, wenn der Netzanschluß der zentralen Steuervorrichtung über einen handelsüblichen Netzstecker an das vorhandene Stromnetz angeschlossen wird und wenn eine Steckdose zum Anschluß der Steuerleitung zur Umwälzpumpe vorgesehen sind. Hierdurch ist es möglich, daß von einem vom zu- ständigen Elektrizitätswerk nicht lizenzierten Heizungsmonteur die gesamte Zentralheizungsnalage an das bauseits vorhandene Stromnetz angeschlossen und in Betrieb genommen werden kann.In a preferred embodiment, it is advantageous if the mains connection of the central control device is connected to the existing mains supply via a commercially available mains plug and if a socket is provided for connecting the control line to the circulation pump. This makes it possible for a heating technician who is not licensed by the competent electricity company to connect the entire central heating system to the existing power supply system and put it into operation can be.

Es ist günstig, wenn ein Verteilerstück im jeweiligen Vor- und Rücklauf eines Heizregisters zwischengeschaltet ist, das einen zusätzlichen Aschluß für die Rohrleitung zu einem, vorzugsweise im gleichen Wohnraum angeordneten, zweiten Heizregister aufweist, und wenn das Verteilerstück zwei Drosseleinrichtungen aufweist, die die jeweilige Durchflußmenge zu bzw. von jedem Heizregister wahlweise einstellt.It is advantageous if a distributor is interposed in the respective supply and return of a heating register that has an additional connection for the pipeline to a second heating register, preferably arranged in the same living space, and if the distributor has two throttling devices that have the respective flow rate to or from each heating register.

Hierdurch wird erreicht, daß die Baulänge des Mehrfachverteilers für den Heizwasservorlauf und -rücklauf kürzer gewählt werden kann, da durch jeweilige paarweise, jeweils um 180° gegeneinander verdrehte Anordnung zweier Verteilerstücke jeweils ein Rohranschluß am Mehrfachverteiler eingespart werden kann. Gleichzeitig kann durch die Drosseleinrichtung die für die jeweilige Länge der Rohrleitung jedes der beiden angeschlossenen Heizregister erforderliche Durchflußmenge eingestellt werden.This ensures that the overall length of the multiple distributor for the heating water supply and return can be chosen shorter, since a pair of pipe connections on the multiple distributor can be saved by paired arrangement of two distributor pieces rotated by 180 ° relative to each other. At the same time, the flow rate required for the respective length of the pipeline of each of the two connected heating registers can be set by the throttle device.

In diesen sind einander entsprechende Teile mit gleichen Bezugszeichen versehen, und es sind alle zum Verständnis der Erfindung nicht notwendigen Einzelheiten forgelassen worden.Further developments and refinements of the invention are characterized in the subclaims and are described below in connection with the exemplary embodiments, partially schematically simplified figures.

Die in den Fig. 1 bis 4 gezeigte Steuervorrichtung besteht aus einem U-förmigen Rahmen 1, der auf einer Längsseite zwei von einem Längsträger 2 aus sich erstreckende zuein- ander parallele erste Fortsätze 3, 4 und auf der diesem Längsträger 2 abgewendeten Seite zwei zueinander parallele zweite Fortsätze 5, 6 trägt. Die beiden zweiten Fortsätze 5, 6 sind durch einen Befestigungsschellen 7 tragenden Querträger 9 verbunden. Der Längsträger 2 trägt zwei senkrecht dazu, gemäß Fig. 1 nach vorne ragende parallele Vorsprünge 10, auf die hintereinander, wie in Fig. 4 besser gezeigt, zuerst ein Mehrfachverteiler 11 für den Heizungsvorlauf und ein Mehrfachverteiler 12 für den Heiz mgsrücklauf mittels Hohlprofilstücken 13 parallel aufgesteckt werden. Jeder Mehrfachverteiler 11 bzw. 12 weist einen von dem Zentralheizungskessel kommenden Vorlauf 14 bzw. Rücklauf 15 auf und ist gleich aufgebaut, jedoch um 180° versetzt aufgesteckt Im Vorlauf 14 bzw. Rücklauf 15 ist jeweils ein Absperrventil 16 sowie ein Entlüftungsventil 17, von dem in Fig. 1 nur eines dargestellt ist, angeordnet. Weiterhin weist jeder Mehrfachverteiler in einer Reihe in gleichgleibenden Abständen angeordnete Rohranschlüsse 19 für den jeweiligen Heizwasservorlauf bzw.-rücklauf von den Heizregistern auf. An diese Rohranschlüsse 19 sind über Stellventile 20.aus flexiblem Kunststoff hergestellte Rohrleitungen 21 angeschlossen, die jeweils paarweise von zwei in Fig. l hintereinander liegenden Rohranschlüssen 19 über eine - nicht dargestellte - im Estrich jedes Wohnraumes verlegte, das jeweilige Heizregister bildende Rohrschleife miteinander verbunden sind. Diese paarweise Anordnung ist aus Fig. 3 besser ersichtlich, wobei die zu einer Rohrschleife zugehörigen Rohrleitungen mittels einer gemeinsamen Befestigungsschelle durch Festziehen einer einzigen Feststellschraube 7a befestigt werden. Der Abstand F des freien Endes der zweiten Fortsätze 5, 6 von dem die Befestigungsschellen 7 tragenden Querträger 9 entspricht wenigstens dem Wert des für die gewählten Rohrleitungen 21 zulässigen Mindestkrümmungsradius zuzüglich der Höhe des im Estrich 22 verlegten Dämmaterials 23. Üblicherweise beträgt dieser Abstand F 20 bis 30 cm.The control apparatus shown in Figs. 1 to 4 consists of a U-shaped frame 1 on a longitudinal side two of a longitudinal beam 2 from extending with respect to each of de r parallel first projections 3, 4 and on this side member 2 side remote carries two mutually parallel second extensions 5, 6. The two second extensions 5, 6 are connected by a cross member 9 carrying mounting clips 7. The longitudinal beam 2 carries two perpendicular to it, 1 protruding parallel projections 1 0 , on the one behind the other, as better shown in Fig. 4, first a multiple distributor 11 for the heating flow and a multiple distributor 12 for the heating mgsrücklauf be plugged in parallel by means of hollow profile pieces 13. Each multiple distributor 11 or 12 has a flow 14 or return 15 coming from the central heating boiler and has the same structure, but is staggered by 180 °. In the flow 14 or return 15 there is a shut-off valve 16 and a vent valve 17, of which in Fig. 1 is shown only one, arranged. Furthermore, each multiple distributor has pipe connections 19 arranged in a row at the same intervals for the respective heating water flow or return from the heating registers. To these pipe connections 19 are connected via control valves 20 made of flexible plastic pipes 21, each of which is connected in pairs by two pipe connections 19 lying one behind the other in FIG. 1 via a pipe loop (not shown) laid in the screed of each living space and forming the respective heating register . This paired arrangement can be seen more clearly from FIG. 3, the pipelines belonging to a pipe loop being fastened by means of a common fastening clamp by tightening a single locking screw 7a. The distance F of the free end of the second extensions 5, 6 from the cross member 9 carrying the fastening clamps 7 corresponds at least to the value of the minimum radius of curvature permissible for the selected pipelines 21 plus the height of the insulating material 23 laid in the screed 22. Usually this distance F is 20 to 30 cm.

Hierdurch wird sichergestellt, daß bei Einbau des Rahmens 1 in die nicht.dargestellte Wandnische eines im Rohbau fertiggestellten Gebäudes genügend Platz für die später installierten Rohrleitungsanschlüsse und für die dafür erforderlichen Mindeskrümmungsradien genügend Platz vorgesehen ist, da erfahrungsgemäß der Rahmen vom Maurer eingebaut und die Installation vom Heizungsinstallateur erst später vorgenommen wird.This ensures that when installing the frame 1 in the not shown wall niche of a building completed in the shell, there is enough space for the pipeline connections installed later and for the required minimum radii of curvature, since experience shows that the frame is inserted by the bricklayer builds and the installation by the heating installer is carried out later.

Wie in Fig. 1 und 3 gezeigt, ist zwischen einem Stellventil 20 und der zugeordneten Rohrleitung 21 ein Verteilerstück 24 im Vorlauf als auch im Rücklauf jeweils paarweise vorgesehen, wodurch eine 1 : 2 Verteilung erreicht wird. Die beiden für ein Heizregister zugeordneten Verteilerstücke 24 sind vorzugsweise gleich aufgebaut und um 180° verdreht eingebaut und so angeordnet, daß der auf einer Längsseite vorgesehene Einzelanschluß 25 auf den jeweils zugeordneten Mehrfachverteiler 11, 12 zeigt und die auf der entgegengesetzten Längsseite angeordneten beiden Anschlüsse 26 jeweils mit den Rohrleitungen im Vorlauf bzw. Rücklauf zweier Rohrschleifen verbunden sind, die vorzugsweise in größeren Räumen angeordnet sind, bei der eine Rohrschleife allein einen zu hohen Durchflußwiderstand aufweisen würde. An diesen beiden Anschlüssen 26 sind unabhängig wirkende Drosseleinrichtungen 27 vorgesehen, die den jeweiligen Rohrquerschnitt wahlweise verändern und von außen über einen Drehknopf 28 betätigbar sind (wie in Fig. 6 gezeigt). Auf dem Außengehäuse ist im Bereich dieses Drehknopfes eine Skala mit zugehörigen Zahlenangaben angegeben, wobei der Drehwinkel des Drehknopfes 27 sich im wesentlichen linear mit dem resultierenden Öffnungsquerschnitt ändert. Der Ventilkörper 29 der Drosseleinrichtung 27 weist hierzu die erforderliche Radialausnehmung 30 auf, wie in den Fig. 7 und 8 besser gezeigt.As shown in FIGS. 1 and 3, a distributor piece 24 is provided in pairs in the flow as well as in the flow between a control valve 20 and the associated pipeline 21, whereby a 1: 2 distribution is achieved. The two distributor pieces 24 assigned for a heating register are preferably constructed identically and installed rotated by 180 ° and arranged such that the individual connection 25 provided on one long side points to the respectively assigned multiple distributor 11, 12 and the two connections 26 arranged on the opposite long side each are connected to the pipes in the flow or return of two pipe loops, which are preferably arranged in larger rooms in which a pipe loop alone would have too high a flow resistance. At these two connections 26, independently acting throttle devices 27 are provided, which optionally change the respective pipe cross section and can be actuated from the outside via a rotary knob 28 (as shown in FIG. 6). In the area of this rotary knob, a scale with associated numerical data is indicated on the outer housing, the angle of rotation of the rotary knob 27 changing essentially linearly with the resulting opening cross section. For this purpose, the valve body 29 of the throttle device 27 has the required radial recess 30, as better shown in FIGS. 7 and 8.

Auf die beiden ersten Fortsätze 3, 4 ist eine zentrale Steuervorrichtung 32 mittels entsprechenden - nicht dargestellten - Hohlprofilstücken aufgesteckt, wobei die Länge dieser ersten Fortsätze 3, 4 derart bemessen ist, daß zwischen deren freiem Ende 3a und 4a und dem Längsträger 2 bequem das längliche Gehäuse 33 dieser zentralen Steuervorrichtung 32 unterzubringen ist. Die beiden ersten Fortsätze 3, 4 dienen ebenfalls wieder als Platzhalter bei der Montage.des Rahmens 1 in der vorgesehenen Wandnische,.so daß bei der Montage des Rahmens 1 der Platz für das Gehäuse 33 bereits eingeplant wird. Das Gehäuse 33 enthält auf der den Mehrfachverteilern 11, 12 zugewendeten Längsseite 34 als separate Koppelglieder ausgebildete Durchführungen 35 sowie innen angeordnete vierpolige Klemmleisten 36, an die über die Durchführungen 35 die die Niederspannung führenden Steuerleitungen 37 zu den in den einzelnen Wohnräumen angeordneten Raumthermostaten 38 angeschlossen sind. Diese Anschlüsse werden bei der Installation durch den Heizungsmonteur nach dem in Fig. 5 gezeigten Schaltbild vorgenommen. Zu jeder Durchführung 35 zugeordnet sind Steckdosen 39 für die Niederspannungszuleitung 40 zu den zugehörigen Stellantrieben 41 für das jeweils zu steuernde Stellventil 20.On the two first extensions 3, 4, a central control device 32 is attached by means of corresponding - not shown - hollow profile pieces, the length of these first extensions 3, 4 being dimensioned such that between the free end 3a and 4a and the side member 2 the elongated member is convenient Housing 33 of this central control device 32 is to be accommodated. The first two extensions 3, 4 also serve as placeholders during the assembly of the frame 1 in the wall niche provided, so that the space for the housing 33 is already planned when the frame 1 is assembled. On the longitudinal side 34 facing the multiple distributors 11, 12, the housing 33 contains bushings 35 designed as separate coupling links and internally arranged four-pole terminal strips 36, to which bushings 35 connect the low-voltage control lines 37 to the room thermostats 38 arranged in the individual living rooms . These connections are made during installation by the heating technician according to the circuit diagram shown in Fig. 5. Sockets 39 for the low-voltage supply line 40 to the associated actuators 41 for the respective control valve 20 are assigned to each bushing 35.

Über ein mit Netzstecker 42 versehenes Netzkabel erfolgt über eine bauseits vorgesehene Netzsteckdose die Stromversorgung der zentralen Steuervorrichtung, wobei die Netzspannung von üblicherweise 220 Volt auf eine Nieder-. spannung von beispielsweise 24 Volt durch einen eingebauten Transformator 44 umgeformt wird. Durch die Wahl einer solchen Niederspannung, mit der die Raumthermostate 38 und die Stellantriebe 41. über vom Installateur zu verlegende Steuerleitungen gespeist werden, ist es möglich, daß die hierzu erforderlichen Elektroinstallationsarbeiten auch von einem vom Elektrizitätswerk nicht lizenzierten Fachmann durchgeführt werden können.The power supply to the central control device takes place via a mains cable provided with mains plug 42 via a mains socket provided by the customer, the mains voltage being usually 220 volts to a low voltage. voltage of, for example, 24 volts is transformed by a built-in transformer 44.
