Damit weist jeder zum Heiz- und/oder Kühlkörper bzw. -fläche H führende Sekundärkreis eine dezentrale Pumpe 13 auf, so dass Thermostatventile an den Wärmetauschern bzw. den Heiz- und/oder Kühlkörpern bzw. -flächen H nicht erforderlich sind, sondern diese dezentralen Pumpen bringen aufgrund ihrer Regelung die erforderliche Menge des Wärmeträgers zu dem jeweiligen Heiz- und/oder Kühlkörper bzw. - fläche H.From the supply chamber 3, the supply lines go from 11, leading to radiators and / or heat sinks or heating and / or cooling surfaces H. After the heat transfer medium has flowed through, the heat transfer medium in each case returns via return lines 12, which open into the return space 4. The feed lines 11 and the return lines 12 are in turn connected via connectors 7 to the device or the housing 1. At the beginning of each flow line and in the embodiment on the side facing the flow chamber side of the connector 7, a decentralized distributor pump 13 is arranged in each case, which sucks the heat transfer medium from the supply chamber 3 and conveys into the supply line. Thus, each leading to the heating and / or heat sink or surface H secondary circuit on a decentralized pump 13, so that thermostatic valves on the heat exchangers or the heating and / or cooling bodies or surfaces H are not required, but these decentralized Pumps bring the required due to their regulation Quantity of the heat carrier to the respective heating and / or cooling body or surface H.

In den Rücklaufleitungen 12, insbesondere an der Stelle, an der sie in den Rücklaufraum 4 münden, sind Rückschlagventile 15 angeordnet, die dafür sorgen, dass der Wärmeträger in die Rücklaufleitungen nicht zurückfließt, sondern vom Rücklaufraum in die Rücklaufleitung 6 des Primärkreises zur Heiz- bzw. Kühlquelle gelangt.In the return lines 12, in particular at the point where they open into the return chamber 4, check valves 15 are arranged, which ensure that the heat carrier does not flow back into the return lines, but from the return space in the return line 6 of the primary circuit for heating or Cooling source passes.

Auf einer Seite insbesondere einer Stirnseite an einem Ende des Gehäuses 1 ist ein elektrischer Kasten 15 befestigt mit elektrischen oder elektronischen Bauteilen und einer Spannungsversorgung über elektrische Anschlüsse. Über die Einrichtung wird die gesamte Vorrichtung mit deren Einzelteile geregelt, insbesondere die Verteilerpumpen 13. Hierzu sind ein Druck- und/oder Strömungssensor 16 und drei Temperatursensoren 17, 18 und 19 in der Kammer 8 im Vorlaufraum 3 und im Rücklaufraum 4 angeordnet. Entsprechend der dort erfassten Werte werden die Verteilerpumpen 13 gesteuert. Hierbei können noch weitere Temperatursensoren in den Sekundärkreisen angeordnet sein. Auch kann zwischen dem Vorlauf 5 und dem Rücklauf 6 ein nicht dargestelltes Druckdifferenzmessgerät angeordnet sein.On one side, in particular a front side at one end of the housing 1, an electrical box 15 is fixed with electrical or electronic components and a power supply via electrical connections. By means of the device, the entire device is regulated with its individual parts, in particular the distributor pumps 13. For this purpose, a pressure and / or flow sensor 16 and three temperature sensors 17, 18 and 19 are arranged in the chamber 8 in the supply space 3 and in the return space 4. In accordance with the values recorded there, the distributor pumps 13 are controlled. In this case, further temperature sensors can be arranged in the secondary circuits. Also, between the flow 5 and the return 6, a pressure differential measuring device, not shown, can be arranged.

Bei der Inbetriebnahme einer oder mehrerer Verteilerpumpen 13 strömt das Medium bzw. der Wärmeträger aus dem Primärkreis 5, 6 in die Vorlaufkammer 8 des Verteilers und von dort über den Durchlass 10 bzw. ein Ventil in den Vorlaufraum 3. Von dort werden die Sekundärkreise 11, 12 von dem Medium durchströmt, deren Verteilerpumpen 13 in Betrieb sind. Danach gelangt das Medium in den Rücklaufraum 4 und strömt von dort wieder in den Primärkreis. Aufgrund der Rückschlagventile am Ende der Rücklaufleitungen 12 werden Rückströmungen und thermische Zirkulationen verhindert.When commissioning one or more distribution pumps 13, the medium or the heat transfer medium flows from the primary circuit 5, 6 in the flow chamber 8 of the manifold and from there via the passage 10 and a valve in the flow chamber 3. From there, the secondary circuits 11, 12 flows through the medium whose distributor pumps 13 are in operation. Thereafter, the medium enters the return chamber 4 and flows from there back into the primary circuit. Due to the check valves at the end of the return lines 12 backflow and thermal circulation are prevented.

Die Ausführungsform nach Fig. 2 unterscheidet sich von der nach Fig. 1 im wesentlichen dadurch, dass der Vorlaufraum 3 mit dem Rücklaufraum 4 miteinander über einen Durchlass 20 verbunden sind, der im Ausführungsbeispiel an einem Ende des Innenraumes der Vorrichtung angeordnet ist. Alternativ kann dieser Durchlass aber auch an anderen Stellen vorgesehen werden. Aufgrund dieser Verbindung der beiden Räume kommt es zu einer teilweisen Vermischung des Wärmeträgers bzw. Mediums beider Räume 3, 4. Diesem Durchlass 20 ist noch eine zusätzliche Beimischfunktion gegeben, aufgrund eines im Durchlassbereich mündenden Kanals 21, der mit dem Vorlauf 5 über die Kammer 8 verbunden ist. Der Wärmeträger des Vorlaufs 5 des Primärkreises gelangt damit nicht wie beim Ausführungsbeispiel nach Fig. 1 über den Durchlass 10 in den Vorlaufraum 3, sondern über den Längskanal 21 zum Durchlass 20, der dort einen Mischraum bildet. Hierdurch wird sichergestellt, dass nur so viel erwärmte oder gekühlte Flüssigkeit in die Vorlaufleitungen 11 gelangt, wie dies jeweils erforderlich ist, das heißt, die dezentralen Verteilerpumpen 13 fördern nicht das Medium des Vorlaufs 5 ungemischt in die Vorlaufleitungen 11, sondern in einer abgemischten Form.The embodiment according to Fig. 2 is different from the after Fig. 1 essentially in that the supply space 3 are connected to the return space 4 with each other via a passage 20, which in the embodiment at one end of the interior of the device is arranged. Alternatively, this passage can also be provided elsewhere. Due to this connection of the two spaces, there is a partial mixing of the heat carrier or medium of both chambers 3, 4. This passage 20 is given an additional admixing function, due to a channel 21 opening into the passage area, which communicates with the flow 5 via the chamber 8 connected is. The heat transfer medium of the flow 5 of the primary circuit thus does not reach as in the embodiment Fig. 1 via the passage 10 in the flow chamber 3, but via the longitudinal channel 21 to the passage 20, which forms a mixing chamber there. This ensures that only as much heated or cooled liquid enters the supply lines 11, as is required in each case, that is, the decentralized distribution pumps 13 do not promote the medium of the supply line 5 unmixed in the supply lines 11, but in a mixed form.

An der Verbindungsstelle zwischen der Vorlaufkammer 8 und dem Längskanal 21 befindet sich eine Zentralpumpe als Beimischpumpe 22, die dafür sorgt, wie viel Medium bzw. Wärmeträger über den Kanal 21 zum Durchlauf 20 bzw. zu dem dortigen Mischraum gelangt. Diese Pumpe 22 ist wiederum über die Elektronik im Kasten 15 geregelt, insbesondere unter Nutzung der angeordneten Sensoren.At the junction between the flow chamber 8 and the longitudinal channel 21 is a central pump as mixing pump 22, which ensures how much medium or heat transfer medium passes through the channel 21 to the passage 20 and to the local mixing space. This pump 22 is in turn regulated by the electronics in the box 15, in particular using the arranged sensors.

Bei der Inbetriebnahme einer oder mehrerer Verteilerpumpen 13 (hierbei können auch eine oder mehrere Verteilerpumpen 13 bis auf Null heruntergefahren sein), strömt das Medium aus der Vorlaufkammer 8 durch die Sekundärkreise in die Rücklaufkammer 4 des Verteilers. Eine Durchströmung des Primärkreises 5, 6 findet solange nicht statt, wie die Beimischpumpe 22 ausgeschaltet ist. Nach dem Einschalten der Beimischpumpe 22 wird aus dem Primärkreislauf dem Sekundärkreis nur so viel Medium zugeführt, bis zum Beispiel eine vorgegebene Mischtemperatur erreicht ist. Dies ist insbesondere auch dann interessant bei kombinierten Systemen wie Radiator plus Flächenheizungen mit unterschiedlichen Anforderungen bezüglich der Vorlauftemperatur. Ein separater Mischer kann aufgrund der Beimischpumpe 22 entfallen.When commissioning one or more distributor pumps 13 (in this case one or more distributor pumps 13 can also be shut down to zero), the medium flows from the supply chamber 8 through the secondary circuits into the return chamber 4 of the distributor. A flow through the primary circuit 5, 6 does not take place as long as the mixing pump 22 is turned off. After switching on the mixing pump 22 from the primary circuit to the secondary circuit only as much medium is supplied until, for example, a predetermined mixing temperature is reached. This is particularly interesting in combined systems such as radiators plus surface heating systems with different requirements regarding the flow temperature. A separate mixer can be omitted due to the mixing pump 22.

Die Verteilervorrichtung ist in den Ausführungen nach Fig. 3 und 4 baukastenförmig modular aufgebaut, in dem einzelne Gehäuseteile jeweils einen Verteilerbereich 1a mit Vorlaufleitungen 11 und Rücklautleitungen 12 bilden, wobei zwei oder mehr dieser Verteilerbereiche aneinander befestigt sind. In der Regel wird jeweils ein Verteilerbereich pro Wohnung, pro Büro oder pro Wohnungsbereich bzw. Bürobereich genutzt. An einem freien Ende ist ein Verteilerbereich 1a durch ein Verschlussteil 1b geschlossen und am anderen Ende ist ein Anschlussbereich 1c als getrenntes Gehäuse angeschlossen, so dass die Vorlaufkammer 8, die Verbindung zum Vorlaufraum 3 und die Verbindung zum Rücklaufraum 4 bildet und an dem ferner Vorlauf 5 und Rücklauf 6 des Primärkreises angeschlossen sind. Der Anschlussbereich 1c braucht mit seinem Gehäuse nur am Gehäuse des Verteilerbereichs 1a befestigt insbesondere angeschraubt zu werden, um eine vollständige Verteilervorrichtung zu erhalten. Der über die Pumpe 22 versorgte Längskanal 21 ist mit dem Längskanal 21 des in Fig. 3 links angeschlossenen zweiten Verteilerbereichs 1a verbunden, so dass auch der zweite Verteilerbereich über die Pumpe 22 versorgt wird. Ferner ist am Gehäuse des Anschlussbereichs 1c auf der den Bereichen 1a abgewandten Seite der Kasten 15 mit den elektrischen und elektronischen Bauteilen befestigt.The distributor device is in the embodiments according to 3 and 4 Modular modular design in which individual housing parts each form a manifold portion 1a with flow lines 11 and Rücklautleitungen 12, wherein two or more of these manifold areas are attached to each other. As a rule, one distribution area is used per apartment, per office or per dwelling area or office area. At one free end, a distributor region 1a is closed by a closure part 1b and at the other end a connection region 1c is connected as a separate housing, so that the flow chamber 8, the connection to the flow chamber 3 and the connection to the return chamber 4 forms and to the further flow and return 6 of the primary circuit are connected. The connection region 1c needs to be fastened with its housing only to the housing of the distributor region 1a, in particular screwed on in order to obtain a complete distributor device. The supplied via the pump 22 longitudinal channel 21 is connected to the longitudinal channel 21 of the in Fig. 3 Connected left second distribution area 1a, so that the second distribution area is supplied via the pump 22. Furthermore, on the housing of the connection region 1c on the side facing away from the regions 1a, the box 15 is fastened to the electrical and electronic components.

Ein solcher modularer Aufbau führt zu einer hohen Flexibilität und Anpassungsfähigkeit. So ist in Fig. 4 eine Ausführungsform gezeigt, bei der auf beiden Seiten des Anschlussbereichs 1c jeweils ein Verteilerbereich 1a angeschlossen ist mit jeweils einem getrennten elektrischen bzw. elektronischen Kasten 15 an dem jeweiligen freien Ende, insbesondere jeweils am Verschlussteil 1b befestigt, so dass die Sekundärkreise des einen Verteilerbereichs 1a unterschiedlich regelbar sind gegenüber den Sekundärkreisen des anderen Verteilerbereichs 1a.Such a modular construction leads to a high flexibility and adaptability. So is in Fig. 4 an embodiment shown in which on both sides of the terminal portion 1c a respective distributor region 1a is connected, each with a separate electrical or electronic box 15 at the respective free end, in particular attached to the closure member 1b, so that the secondary circuits of the one distributor region 1a different can be regulated with respect to the secondary circuits of the other distribution area 1a.

Im Anschlussbereich 1c sind zwei Pumpen dargestellt. Die obere Pumpe 22 fördert als Beimischpumpe in den Kanal 21 mit der obengenannten Funktion und die darunter liegende Pumpe 26 fördert vom Vorlauf 5 direkt in den Vorlaufraum 3, so dass der Anschlussbereich 1c sowohl wie die Ausführung nach Fig. 1 als auch alternativ wie die Ausführung nach Fig. 2 arbeiten kann. Aufgrund des Förderdrucks der Pumpe 26 sind die dezentralen Pumpen 13 nicht von dem Druckverlust des Primärkreises 5, 6 beeinflusst.In connection area 1c two pumps are shown. The upper pump 22 promotes as Beimischpumpe in the channel 21 with the above function and the underlying pump 26 promotes the flow 5 directly into the flow chamber 3, so that the connection area 1c as well as the embodiment according to Fig. 1 as well as alternatively as the execution after Fig. 2 can work. Due to the Delivery pressure of the pump 26, the decentralized pumps 13 are not affected by the pressure loss of the primary circuit 5, 6.

Hierbei kann im Durchlassbereich 20 zwischen den Räumen 3 und 4 an der Stelle 27 ein Absperrteil angeordnet, das auch als Ventil arbeiten kann, so dass entweder die beiden Räume 3, 4 voneinander vollständig getrennt sind oder aber mehr oder weniger eine Verbindung miteinander besitzen. Auch dieses Absperrteil bzw. Ventil 27 ist wie alle anderen Ventile über die Elektronik im Kasten 15 regelbar. Erfindungsgemäss sind die dezentralen Pumpen 13 innerhalb des Gehäuses 1 der Vorrichtung angeordnet. Zusätzlich sind folgende Ausführungen möglich:
