Description

Insbesondere in Landwirtschaft, Industriehallen und Grossküchen, wo Ablufttemperaturen von ca. 20 bis 300C herrschen, werden Wärmetauscher verwendet, um die warme Abluft nicht ungenutzt ins Freie auszulassen. Die Rückgewinnung von Wärme aus der warmen Abluft wird durch Wärmeabgabe an die durch den Wärmetauscher z.B. in Ställe oder Industriehallen eingeführte Frischluft erzielt. Dadurch werden die Betriebskosten bis zu ca. 60% reduziert. Die vorerwärmte, durch den Wärmetauscher zugeführte Frischluft wird dann mit einem kleinen Heizaufwand auf die Betriebstemperatur gebracht.In particular in agriculture, industrial halls and canteen kitchens, where exhaust air temperatures of around 20 to 30 ° C prevail, heat exchangers are used so that the warm exhaust air is not used unused outside. The recovery of heat from the warm exhaust air is achieved by giving off heat to the fresh air introduced through the heat exchanger, for example in stables or industrial halls. This reduces operating costs by up to 60%. The preheated fresh air supplied by the heat exchanger is then brought to the operating temperature with a small amount of heating.

Es sind Wärmetauscher mit Metall- oder Glasplatten bekannt, welche in einem Gehäuse aus Stahlblech eingesetzt sind. Die Platten sind im Gehäuse im geringen Abstand voneinander und parallel zueinander in vertikaler Weise eingebaut. Die warme Abluft und die kalte Frischluft werden getrennt zwischen den Glasplatten im Kreuzstrom so durchgeführt, dass die Abluft z.B. seitlich und die Frischluft von oben zugeführt wird. Beim Durchströmen des Platten-Wärmetauschers übernimmt der kältere Luftstrom den weitaus grössten Teil der im anderen Luftstrom vorhandenen Wärme.Heat exchangers with metal or glass plates are known which are used in a housing made of sheet steel. The plates are installed in the housing at a short distance from one another and in parallel in a vertical manner. The warm exhaust air and the cold fresh air are conducted separately between the glass plates in a cross flow so that the exhaust air e.g. sideways and the fresh air is supplied from above. When flowing through the plate heat exchanger, the colder air flow takes over the vast majority of the heat present in the other air flow.

Bei Metallplatten treten schon nach relativ kurzer Gebrauchsdauer Reinigungs- und andere Schwierigkeiten auf. Die aus Glas bestehenden Wärmetauscherplatten sind zerbrechlich und weisen ein ziemlich grosses Gewicht auf. Auch die Herstellungskosten dieser Glasplatten sind verhältnismässig hoch.With metal plates, cleaning and other difficulties arise after a relatively short period of use. The heat exchanger plates made of glass are fragile and are quite heavy. The manufacturing costs of these glass plates are also relatively high.

In der CH-PS 611 701 ist ein Wärmetauscher mit Rohren beschrieben, die aus Borsilikatglas bestehen. Die Glasrohre sind in einem Metallrahmen vertikal dicht aneinander gereiht und haben einen Durchmesser von etwa 13 mm. Hier wird die Abluft durch die Spalten zwischen den Rohren und die Frischluft durch den Innenraum der Rohre geführt. Ein solcher Wärmetauscher soll für höhere Betriebstemperaturen als 30°C verwendbar sein.CH-PS 611 701 describes a heat exchanger with tubes made of borosilicate glass. The glass tubes are arranged vertically close together in a metal frame and have a diameter of approximately 13 mm. Here the exhaust air is led through the gaps between the pipes and the fresh air through the interior of the pipes. Such a heat exchanger should be usable for operating temperatures higher than 30 ° C.

Auch diese, aus Borsilikatglas bestehenden Rohre, haben mindestens die Nachteile des ziemlich grossen Gewichtes und der ziemlich hohen Herstellungskosten.These pipes, which are made of borosilicate glass, have at least the disadvantages of the rather large weight and the rather high manufacturing costs.

Der Erfindung lag die Aufgabe zugrunde, einen Wärmetauscher aus einem solchen Material zu schaffen, das eine gute Stabilität hat, wärmebeständig und unempfindlich gegen Kälte ist und im Unterdruck arbeiten kann. Die Herstellungskosten eines solchen Materials sollen wesentlich niedriger gehalten werden als diejenigen der bekannten Materialien.The invention had for its object to provide a heat exchanger made of such a material that has good stability, is heat-resistant and insensitive to cold and can work in negative pressure. The manufacturing costs of such a material should be kept significantly lower than those of the known materials.

Diese Aufgabe wird erfindungsgemäss durch die Verwendung von Stegdoppelplatten aus Kunststoff gelöst, die zum Führen von Frisch- und Abluft in einem, insbesondere für Landwirtschaft, Grossküchen oder Industriehallen bestimmten Gegenstrom- oder Kreuzstromwärmetauscher eingesetzt werden.This object is achieved according to the invention by the use of double-walled plastic sheets which are used for guiding fresh and exhaust air in a counterflow or crossflow heat exchanger, in particular intended for agriculture, canteen kitchens or industrial halls.

Mit Vorteil hat jede solche Stegdoppelplatte eine Dicke von höchstens 15 mm und die Stegdoppelplatten sind im Wärmetauscher so untergebracht, dass der Abstand zwischen jeweils zwei benachbarten Stegdoppelplatten höchstens 15 mm beträgt.Each such double wall plate advantageously has a thickness of at most 15 mm and the double wall plates are accommodated in the heat exchanger such that the distance between two adjacent double wall plates is at most 15 mm.

Um die äusseren Wände der Stegdoppelplatten, an welchen die Abluft mit Schmutzpartikeln strömt, reinigen zu können, ist es vorteilhaft, zwischen jeweils zwei benachbarten Stegdoppelplatten eines Gegenstrom-Wärmetauschers an deren oberem Rand ein Kunststoffröhrchen mit Löchern zum Bespritzen mit Wasser dieser äusseren Wände zu befestigen.Around the outer walls of the double-wall sheets, on which the exhaust air flows with dirt particles, To be able to clean, it is advantageous to fasten a plastic tube with holes for spraying with water from these outer walls between each two adjacent web double plates of a countercurrent heat exchanger.

Die Erfindung wird nachstehend anhand der Zeichnungen beispielsweise näher erläutert. Es zeigen

  • Fig. 3 eine schematische Darstellung des Einbaues eines Gegenstromwärmetauschers und
  • Fig. 4 eine schematische Darstellung des Einbauses eines Kreuzstromwärmetauschers.
The invention is explained in more detail below with reference to the drawings, for example. Show it
  • 1 is a perspective view of a counterflow heat exchanger, in which the fresh air and exhaust air flow are indicated,
  • 2 is a view of a tube of the counterflow heat exchanger,
  • Fig. 3 is a schematic representation of the installation of a counterflow heat exchanger and
  • Fig. 4 is a schematic representation of the installation of a cross-flow heat exchanger.

Die als Führungsplatten für Ab- und Frischluft in dem Wärmetauscher verwendeten Stegdoppelplatten aus Kunststoff sind bis 140°C wärmebeständig und gegen Kälte bis -40°C unempfindlich. Sie haben eine ausgezeichnete Stabilität und können einen Unterdruck bis 50 mm Wassersäule ohne Leistungseinbusse aufnehmen. Solche Stegdoppelplatten sind marktüblich und preiswert.The plastic double-wall plates used as guide plates for exhaust and fresh air in the heat exchanger are heat-resistant up to 140 ° C and insensitive to cold down to -40 ° C. They have excellent stability and can absorb a vacuum of up to 50 mm water column without loss of performance. Such double-wall sheets are customary and inexpensive.

Die Dicke der einzelnen Stegdoppelplatten 1 beträgt 4 bis 15 mm. Die Doppelstegplatten sind nebeneinander vertikal zu einem Block zusammengebaut. Der Abstand zweier benachbarter Doppelstegplatten 1 nebeneinander macht ebenfalls 4 bis 15 mm aus, je nach der Dicke der Stegdoppelplatte 1.The thickness of the individual double-wall sheets 1 is 4 to 15 mm. The double-wall sheets are vertically assembled into a block. The distance between two adjacent double-wall sheets 1 next to one another also amounts to 4 to 15 mm, depending on the thickness of the double-wall sheet 1.

Wie aus der ersten Figur ersichtlich ist, wird die kalte Frischluft durch die durch die Stege 1a der Stegdoppelplatten 1 begrenzten Räume zugeführt. Die warme Abluft, die z.B. in Viehställen eine Temperatur von 20°C hat und voll von Ammoniak und Staub ist, wird durch die Spalten zwischen den einzelnen zueinanander parallel verlaufenden Stegdoppelplatten 1 geführt. Wenn die kalte Frischluft eine Temperatur von etwa 0°C und die Abluft eine Temperatur von etwa 20°C aufweist, übernimmt die kältere Frischluft beim Durchströmen des Wärmetauschers vom grössten Teil die in der Abluft vorhandene Wärme.As can be seen from the first figure, the cold fresh air is supplied through the spaces delimited by the webs 1a of the web double plates 1. The warm exhaust air, which has a temperature of 20 ° C in cattle houses and is full of ammonia and dust, is combined by the gaps between the individual out other parallel web double plates 1 out. If the cold fresh air has a temperature of about 0 ° C and the exhaust air has a temperature of about 20 ° C, the colder fresh air takes over most of the heat in the exhaust air as it flows through the heat exchanger.

Dabei findet keine Mischung der Albuft mit der Frischluft statt.There is no mixing of the air with the fresh air.

Die erwärmte Frischluft kann beim Austritt aus dem Wärmetauscher eine Temperatur von etwa 10°C haben. Der Wirkungsgrad ist hier ungefähr 50%: er kann aber je nach dem Temperaturgefälle, der Luftfeuchtigkeit usw. bis zu 85% gesteigert werden.The heated fresh air can have a temperature of around 10 ° C when it exits the heat exchanger. The efficiency here is about 50%: depending on the temperature gradient, air humidity, etc., it can be increased by up to 85%.

Die Stegdoppelplatten 1 sind in einem Gehäuse 7 untergebracht. Bei einem Gegenstromwärmetauscher A besteht dieses Gehäuse 7 aus zwei Seitenwänden 4, einer oberen Wand 6 und einer abgekürzten unteren Wand 5. Wie aus den Figuren 1 und 3 ersichtlich ist, tritt die warme Abluft an einem Ende des Gehäuses 7, das von der unteren Wand 5 nicht abgedeckt ist, in den Gegenstromwärmetauscher und strömt dann durch die Spalten zwischen den einzelnen Stegdoppelplatten 1 im Gegenstrom zur Frischluft und tritt auf dem anderen Ende des Gehäuses 7 als kalte Abluft aus, welches Ende ebenfalls von der unteren Wand 5 nicht abgedeckt ist. Wie aus der Figur 3 weiter ersichtlich ist, wird der Abluftstrom durch einen Abluftventilator 8 erzeugt. Die kalte Abluft wird dann ins Freie ausgelassen.The web double plates 1 are accommodated in a housing 7. In a counterflow heat exchanger A, this housing 7 consists of two side walls 4, an upper wall 6 and an abbreviated lower wall 5. As can be seen from FIGS. 1 and 3, the warm exhaust air exits at one end of the housing 7, which is from the lower wall 5 is not covered, in the counterflow heat exchanger and then flows through the gaps between the individual web double plates 1 in counterflow to the fresh air and emerges on the other end of the housing 7 as cold exhaust air, which end is also not covered by the lower wall 5. As can also be seen from FIG. 3, the exhaust air flow is generated by an exhaust air fan 8. The cold exhaust air is then released outside.

Die kalte Frischluft wird durch einen Zuluftventilator 9 in Zwangsstrom durch die durch die Stege 1a begrenzten Räume durchgeführt, wobei sie die Wärme von der Abluft übernimmt. Die erwärmte Frischluft wird in den Innenraum des Gehäuses 10 geblasen.The cold fresh air is passed through a supply air fan 9 in a forced flow through the spaces delimited by the webs 1a, where it takes over the heat from the exhaust air. The heated fresh air is blown into the interior of the housing 10.

Dieser Gegenstrom-Wärmetauscher A kann bei einer Ablufttemperatur von ca. 20 bis 30°C und einer Frischlufttemperatur bis von minus 120C verwendet werden, wobei sich kein Eis im Abluftteil bildet.This counterflow heat exchanger A can be used at an exhaust air temperature of approx. 20 to 30 ° C and a fresh air temperature of down to minus 12 0 C, whereby no ice forms in the exhaust air part.

Der in der Figur 4 dargestellte Kreuzstrom-Wärmetauscher B kann bei einer Ablufttemperatur von ca. 20 bis 30°C und einer Frischlufttemperatur bis minus 7°C verwendet werden. Bei diesem Kreuzstrom-Wärmetauscher B bildet sich im Abluftteil viel schneller Eis als bei dem Gegenstrom-Wärmetauscher A. Bei dem Kreuzstrom-Wärmetauscher B weist das Gehäuse 7 nur die Seitenwände 4 auf, die miteinander durch Abschlusswinkel verbunden sind, so dass die Abluft durch den Wärmetauscher B von unten nach oben unbehindert strömen kann.The cross-flow heat exchanger B shown in FIG. 4 can be used at an exhaust air temperature of approximately 20 to 30 ° C. and a fresh air temperature of down to minus 7 ° C. In this cross-flow heat exchanger B, ice forms much faster in the exhaust air section than in the counter-flow heat exchanger A. In the cross-flow heat exchanger B, the housing 7 has only the side walls 4, which are connected to one another by closing angles, so that the exhaust air through the Heat exchanger B can flow freely from the bottom to the top.

Die Aussenwände der Stegdoppelplatten 1 eines Gegenstrom-Wärmetauschers A sind an Ihren oberen Rändern mit Kunststoffröhrchen 2 mit Löchern 3 versehen, die zum Bespritzen mit Wasser der äusseren Wände der Stegdoppelplatten 1 dienen. Bei dem Kreuzstromwärmetauscher B sind zum Bespritzen von äusseren Wänden der Stegdoppelplatten 1 nicht dargestellte Düsen vorhanden.The outer walls of the double wall plates 1 of a countercurrent heat exchanger A are provided on their upper edges with plastic tubes 2 with holes 3, which are used for spraying water on the outer walls of the double wall plates 1. In the cross-flow heat exchanger B, nozzles (not shown) are provided for spraying outer walls of the web double plates 1.

Das auf die Aussenwände der Doppelstegplatten 1 gespritzte Wasser, um diese von verschiedenen Schmutzabsätzen zu reinigen, geht als Kondenswasser mit der Abluft weg oder wird kanalisiert.The water sprayed onto the outer walls of the double-wall sheets 1 in order to clean them from various dirt deposits goes away as condensed water with the exhaust air or is channeled.

Durch die Verwendung der oben beschriebenen Stegdoppelplatten zum Führen von Frisch- und Abluft in Gegenstrom- oder Kreuzstrom-Wärmetauschern werden die Herstellungskosten derselben wesentlich gesenkt. Die Kunststoffstegdoppelplatten gewährleisten eine sehr gute Wärmeübertragung und das Gewicht derselben ist herabgesetzt. Solche Wärmetauscher werden ausser den eingangs erwähnten Gebieten überall dort verwendet, wo gelüftet wird, wie in Schwimmbädern, klimatisierten Wohnräumen usw.By using the above-described web double plates for guiding fresh and exhaust air in counterflow or crossflow heat exchangers, the manufacturing costs of the same are significantly reduced. The plastic web double plates ensure very good heat transfer and the weight of the same is reduced. Except for the areas mentioned at the beginning, such heat exchangers are used wherever ventilation takes place, such as in swimming pools, air-conditioned living rooms, etc.
