Abstract

In the apparatus for heat transfer with a liquid heat carrier, at least one flat heat exchanger (1) to receive or give up heat, a duct system with a circulating pump (3), a heat exchanger (2), and a pressure regulating device (4) are connected together such that the circulating pump (3) is installed behind the flat heat exchanger (1), and the apparatus is closed. In a preferred embodiment, the apparatus is permanently and completely under reduced pressure, and the circulating pump (3) is installed in front of, and the pressure regulating device (4) behind, the heat exchanger (2). <IMAGE>

Description

Vorrichtung zur Wärmeübertragung Gegenstand der Erfindung ist eine Vorrichtung zur Wärmeübertragung mit einem flüssigen Wärmeträger, bei der mindestens ein Flachwärmetauscher zur Aufnahme bzw Abgabe von Wärme, eirr Leitungssystem mit Umwälzpumpe, ein Wärmetauscher und eine Druckregeleinrichtung miteinander verbunden sind.Device for heat transfer The invention is a Device for heat transfer with a liquid heat carrier, in which at least a flat heat exchanger for absorbing or releasing heat, with a pipe system Circulation pump, a heat exchanger and a pressure control device connected to one another are.

Aus DE-OS 28 09 690, DE-OS 30 02 787 und DE-OS 30 4t 855 sind h5-rmeübertraaungsanlagen mit einem flüssigen Wärmeträger bekannt, die teilweise im Unterdruckbetrieb arbeiten.From DE-OS 28 09 690, DE-OS 30 02 787 and DE-OS 30 4t 855 are h5-rmeübertraaungsanlagen known with a liquid heat transfer medium, some of which work in negative pressure mode.

Diese Anlagen gestatten es zwar einerseits, das einfach aufgebaute Flachwärmetauscher verwendet werden, sie haben aber den Nachteil, daß der Flachwärmetauscher immer an der höchsten Stelle sein muß, d.h., es ist nicht möglich, daß der Flachwärmetauscher unterhalb des Wärmetauscheu angebracht wird. So ist z.B. eine Fußbodenheizung im tiefsten Geschoß eines Bauwerks nicht möglich.On the one hand, these systems allow the simply structured Flat heat exchangers are used, but they have the disadvantage that the flat heat exchanger always on must be in the highest position, i.e. it is not possible that the flat heat exchanger is attached below the heat exchanger. E.g. underfloor heating in the lowest storey of a building is not possible.

Es war daher Aufgabe der Erfindung, eine Vorrichtung zur Wärmeübertragung mit einem flüssigen Wärmeträger zu finden, die zwar die Vorteile der teilweise im Jnterdruckbetrieb arbeitenden Wärmeübertragungsanlagen hat, bei der es aber auch möglich ist, den Flachwärmeaustauscher an der tiefsten Stelle der Vorrichtung anzubringen. Die Lösung der Aufgabe erfolgt dadurch, daß die Umwälzpumpe (3) hinter dem Flachwärmetauscher (1) installiert ist und die Vorrichtung geschlossen ist.It was therefore the object of the invention to provide a device for heat transfer to find with a liquid heat transfer medium, although the advantages of the partial im Vacuum operation has working heat transfer systems, but also has it is possible to attach the flat heat exchanger at the lowest point of the device. The object is achieved in that the circulation pump (3) is behind the flat heat exchanger (1) is installed and the device is closed.

Eine derartige Vorrichtung kann entweder teilweise oder dauernd und vollständig unter Unterdruck stehen, je nach dem an der Druckregeleinrichtung (4) vorgegebenen Vordruck.Such a device can be either partial or permanent and are completely under negative pressure, depending on the pressure control device (4) specified form.

Dieser Druck soll so eingestellt sein, daß zumindest der Flachwärmeaustauscher, bevorzugt aber die ganze Vorrichtung, unter leichtem Unterdruck stehen. Er darf nicht so niedrig sein, daß Teile des Wärmeträgers verdampfen.This pressure should be set so that at least the flat heat exchanger, but preferably the entire device is under a slight negative pressure. He is allowed to not be so low that parts of the heat transfer medium evaporate.

Der Unterdruck beim tiefliegenden Flachwärmetauscher ergibt den zusätzlichen Vorteil, daß bei einer evtl. Beschädigung kein Wärmeträger ausfließt. Dieser Vorteil kann noch gesteigert werden, indem man vor und hinter dem Flachwärmetauscher Rückschlagventile einbaut.The negative pressure in the low-lying flat heat exchanger results in the additional Advantage that no heat transfer medium escapes in the event of damage. This advantage can be increased by adding check valves upstream and downstream of the flat heat exchanger built in.

In einer bevorzugten Ausfuhrung ist zudem die Umwälzpumpe (3) vor dem bfarmetauscher (2) installiert und die Gruckregeleinrichtung (4) ist in Strömungsrichtung hinter dem Wärmetauscher (2) installiert.In a preferred embodiment, the circulation pump (3) is also present the farm exchanger (2) installed and the pressure control device (4) is installed downstream of the heat exchanger (2) in the direction of flow.

Die beigefügte Zeichnung demonstriert die bevorzugte Anordnung in der geschlossenen Vorrichtung mit dem Flachwärmeaustauscher (1) an der tiefsten Stelle der Vorrichtung, der Umwälzpumpe (3) hinter dem Flachwärmeaustauscher (1) und der Druckregeleinrichtung (4) hinter dem Wärmetauscher (2).The accompanying drawing demonstrates the preferred arrangement in the closed device with the flat heat exchanger (1) at the deepest Place of the device, the circulation pump (3) behind the flat heat exchanger (1) and the pressure control device (4) downstream of the heat exchanger (2).
