Description

Die Erfindung bezieht sich auf einen Gegenstromwärmetauscher gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a countercurrent heat exchanger according to the preamble of claim 1.

Ein derartiger Gegenstromwärmetauscher ist durch die EP-A-0 844 454 bekannt. Bei diesem Wärmetauscher sind im Bereich der Rechteckform Profilkanäle vorgesehen, welche den Wärmeaustausch zwischen den Gasströmen thermodynamisch günstig beeinflussen. Im Bereich der Dreieckformen, welche dem Einlaßabschnitt und dem Auslaßabschnitt entsprechen, sind einige Stützelemente vorgesehen, welche bei übereinanderliegenden Platten im Bereich der beiden Endabschnitte eine ausreichende Stabilität gewährleisten und auch als Leitelemente für die Gase dienen.Such a countercurrent heat exchanger is known from EP-A-0 844 454. In this heat exchanger profile channels are provided in the rectangular shape, which influence the heat exchange between the gas streams thermodynamically favorable. In the region of the triangular shapes, which correspond to the inlet section and the outlet section, some support elements are provided, which ensure sufficient stability in superimposed plates in the region of the two end portions and also serve as guide elements for the gases.

Ein weiterer Gegenstromwärmetauscher ist durch die JP 08 200972 A bekannt. Dieser Wärmetauscher zeigt ebenfalls sechseckförmige Profilplatten, wobei die Profilplatten für den ersten Luftstrom und die Profilplatten für den zweiten Luftstrom in Plattenebene um 180° gegeneinander gedreht sind und zwischen je zwei Profilplatten eine Trennschicht angeordnet ist.Another countercurrent heat exchanger is known from JP 08 200972 A. This heat exchanger also shows hexagonal profile plates, wherein the profile plates for the first air flow and the profile plates for the second air flow in the plate plane are rotated by 180 ° from each other and between each two profile plates, a release layer is arranged.

Ein weiterer Wärmetauscher ist durch die DE 198 13 119 A1 bekannt. Bei diesem Wärmetauscher werden die Profilplatten für die beiden Luftströme abwechselnd in unterschiedlicher Schrägstellung übereinandergelegt. Das so gebildete Paket von Profilplatten, welche eine rechteckförmige Struktur haben, wird in einen aufgeschnittenen Plattenwärmeübertrager eingefügt, welcher die Form eines lang gestreckten Quaders mit spitzwinkligen Enden hat, so daß die Form des Längsschnitts dieses Wärmetauschers mit den rechteckförmigen Profilplatten insgesamt sechseckig ist. Die Profilkanäle der Profilplatten laufen zu den Stirnseiten hin in ebene, in der Profilplattenmittellinie liegende Platten aus. Die Verteilung der Luftströme erfolgt abwechselnd in entgegengesetzter Richtung. Mit dem bekannten Wärmetauscher wird keine zufriedenstellende Wärmerückgewinnung erzielt.Another heat exchanger is known from DE 198 13 119 A1. In this heat exchanger, the profile plates for the two air streams are alternately superimposed in different inclination. The thus formed package of profile plates, which have a rectangular structure, is inserted into a sliced plate heat exchanger, which has the shape of an elongated cuboid with acute-angled ends, so that the shape of the longitudinal section of this heat exchanger with the rectangular profile plates as a whole is hexagonal. The profile channels of the profile plates run out to the end faces in flat, lying in the profile plate center line plates. The distribution of the air flows takes place alternately in the opposite direction. With the known heat exchanger no satisfactory heat recovery is achieved.

Durch das DE 296 20 248 U1 ist ebenfalls ein Gegenstromwärmetauscher mit Profilplatten bekannt, wobei jede Profilplatte eine Rechteckform aufweist. Der Wärmetauscher hat wiederum insgesamt eine sechseckige Form, wobei der Ein- und Austritt desselben Luftstromes in Längsrichtung des Wärmetauschers gesehen auf der gleichen Seite erfolgt.By DE 296 20 248 U1 a countercurrent heat exchanger with profiled plates is also known, each profile plate has a rectangular shape. The heat exchanger in turn has a total of a hexagonal shape, wherein the inlet and outlet of the same air flow in the longitudinal direction of the heat exchanger takes place on the same side.

Durch die DE 196 35 552 C1 ist weiterhin ein Gegenstromwärmetauscher mit Profilplatten bekannt. Der Gegenstromwärmetauscher hat insgesamt eine sechseckige Struktur, die Profilplatten weisen jedoch eine Rechteckform auf. Auch bei einem in der GB 12 23 752 beschriebenen Wärmetauscher sind die Profilplatten insgesamt rechteckig ausgebildet.From DE 196 35 552 C1 a countercurrent heat exchanger with profile plates is also known. The counterflow heat exchanger has an overall hexagonal structure, but the profile plates have a rectangular shape. Even with a heat exchanger described in GB 12 23 752, the profile plates are rectangular overall.

Die Aufgabe der Erfindung wird somit darin gesehen, den Gegenstromwärmetauscher der eingangs genannten Art derart weiterzuentwickeln, daß ein guter Temperaturausgleich und eine gute Wärmerückgewinnung erzielt wird.The object of the invention is thus seen to develop the countercurrent heat exchanger of the type mentioned in such a way that a good temperature compensation and good heat recovery is achieved.

Zur Lösung dieser Aufgabe ist erfindungsgemäß der Gegenstromwärmetauscher gemäß dem Oberbegriff des Anspruches 1 entsprechend dem kennzeichnenden Teil dieses Anspruchs ausgebildet.To solve this problem, the countercurrent heat exchanger according to the preamble of claim 1 is formed according to the characterizing part of this claim according to the invention.

Bei dem erfindungsgemäßen Gegenstromwärmetauscher ist die gesamte Grundfläche mit den sechseckförmigen Profilplatten überdeckt, so daß über die gesamte Längsschnittfläche gesehen dieser Wärmetauscher zur Wärmerückgewinnung optimal genutzt werden kann. Damit wird ein guter Temperaturausgleich und eine gute Wärmerückgewinnung erzielt. Bei dem bekannten Wärmetauscher konnte als effizienter Temperaturausgleichsbereich lediglich der rechteckförmige Teil der Profilplatten und damit nicht die gesamte Längsschnittfläche dieses bekannten Wärmetauschers zur effektiven Wärmerückgewinnung genutzt werden.In the countercurrent heat exchanger according to the invention, the entire base surface is covered with the hexagonal profile plates, so that seen over the entire longitudinal sectional area of this heat exchanger can be optimally used for heat recovery. This achieves good temperature compensation and good heat recovery. In the known heat exchanger could be used as efficient temperature compensation area only the rectangular part of the profile plates and thus not the entire longitudinal sectional area of this known heat exchanger for effective heat recovery.

Weiterhin ist jeder Profilkanal der ersten Dreieckform und jeder Profilkanal der zweiten Dreieckform strömungsmäßig mit zwei Profilkanälen der Rechteckform oder mit einem Profilkanal der Rechteckform verbunden, welcher die zweifache Breite gegenüber der Breite des Profilkanals jeder Dreieckform aufweist, wobei die Profilkanäle der Dreieckformen in einem Winkel von 60° zur Längsrichtung verlaufen. Bei jeder Dreieckform ist das Verhältnis von Hypothenuse zu Höhe 3.5 zu 1.Furthermore, each profile channel of the first triangular shape and each profile channel of the second triangular shape is fluidly with two profile channels of the rectangular shape or connected to a profile channel of the rectangular shape, which has twice the width compared to the width of the profile channel of each triangular shape, wherein the profile channels of the triangular shapes extend at an angle of 60 ° to the longitudinal direction. For each triangle shape, the ratio of hypotenuse to height is 3.5 to 1.

Das Lüftungsgerät weist eine Abluftkammer, eine Abluft-Zwischenkammer und eine Fortluftkammer für den ersten Luftstrom sowie eine Frischluftkammer, eine Frischluft-Zwischenkammer und eine Zuluftkammer für den zweiten Luftstrom auf. Mindestens ein Peltierelement ist zum Kühlen oder Erwärmen der Luftströme zwischen der Abluftkammer und der Frischluftkammer oder der Fortluftkammer und der Zuluftkammer angeordnet, wobei das Peltierelement im wesentlichen eine Trennwand zwischen der Abluftkammer und der Frischluftkammer oder der Fortluftkammer und der Zuluftkammer bildet. Damit ist ein kompaktes Lüftungsgerät geschaffen, mit welchem der Frischluftstrom gekühlt oder erwärmt werden kann und zusätzlich auch der Abluftstrom gekühlt oder erwärmt werden kann.The counterflow heat exchanger may be arranged in an air handling unit. The ventilation device has an exhaust air chamber, an exhaust air intermediate chamber and an exhaust air chamber for the first air flow and a fresh air chamber, a fresh air intermediate chamber and a supply air chamber for the second air flow. At least one Peltier element is arranged for cooling or heating the air streams between the exhaust air chamber and the fresh air chamber or the exhaust air chamber and the Zuluftkammer, wherein the Peltier element forms a partition wall between the exhaust air chamber and the fresh air chamber or the exhaust air chamber and the supply air chamber substantially. Thus, a compact ventilation unit is created, with which the fresh air flow can be cooled or heated and in addition, the exhaust air flow can be cooled or heated.
