Abstract

An intermediate heat exchanger for use in air conditioning systems is constructed from at least three concentrically arranged pipes (5-9). These pipes are so attached to each other that they form intermediate annular spaces having half their section blanked off by means of half rings (15-18). The constructional pipes (5-9) are attached so that inlet and outlet chambers (1-4) are formed at their respective ends. The innermost pipe is covered or blanked off by means of staggered semi-circular discs (19-24) at its opposing ends.

Mittelbarer Wärmeaustauscher für KlimaanlagenIndirect heat exchanger for air conditioning systems

Die Erfindung betrifft einen mittelbaren Wärmeaustauscher, der in Klimaanlagen dazu dient, entweder im Winter mit der Wärme der Abluft die frische Zuluft vorzuwärmen, oder im Sommer mit kühler Abluft warme Zuluft zu kühlen.The invention relates to an indirect heat exchanger which is used in air conditioning systems, either in the winter with the heat Exhaust air to preheat the fresh supply air, or in summer to cool warm supply air with cool exhaust air.

Mittelbare Wärmeaustauscher sind an sich bekannt. Der Austausch geschieht in Doppelrohren, d.h. in einem größeren Rohrmantel, der z.B. von heißer Luft durchflossen wird, verlaufen eine größere Anzahl von Rohren, in denen die kalte Luft oder kaltes Wasser einfließt und sich darin erwärmt. Es gibt auch Platten- und .Spiralaustauscher mittels Heiz- und Kühlschlangen. Diese Wärmeaustauscher sind in allen Fällen von ihren Bauelementen her gesehen Sonderanfertigungen und benötigen baulich erheblichen Raum.Indirect heat exchangers are known per se. The exchange takes place in double pipes, i.e. in a larger pipe jacket, the E.g. if hot air flows through it, there are a large number of pipes in which the cold air or cold water flows and warms up in it. There are also plate and spiral exchangers by means of heating and cooling coils. In all cases, these heat exchangers are custom-made in terms of their components and require considerable structural space.

Der Erfindung liegt die Aufgabe zu Grunde, einen Wärmeaustauscher zu entwickeln, der unter Verwendung handelsüblicher Vorprodukte hergestellt und baulich klein gehalten werden kann.The invention is based on the object of developing a heat exchanger which, using commercially available preliminary products can be produced and kept structurally small.

Die Aufgabe wird bei einem mittelbaren Wärmeaustauscher für Klimaanlagen nach der Erfindung dadurch gelöst, daß der Wärmeaustauscher aus mindestens drei konzentrisch ineinander gestellten, zwischen Ein- und Ausblaskammern angeordneten Rohren besteht und daß der Zwischenraum zwischen aufeinander folgenden Rohren jeweils auf dein h.iib(=-.n Um.tanq. vor.

abwechselnd an ihren Enden durch Halbringe verschlossen ist. Hierdurch wird erreicht, daß z.B. die warme Luft von unten her in die eine halbkreisförmig unten offene Hälfte der Zwischenräume eintritt und im anderen Halbkreis der gleichen Zwischenräume oben wieder austritt. Die kalte Luft tritt von oben her in die dazwischen liegenden oben offenen Zwischenräume ein und in dem anderen Halbkreis der gleichen Zwischenräume unten erwärmt aus.is alternately closed at their ends by half rings. Through this it is achieved, for example, that the warm air enters from below into the half of the intermediate spaces that is open at the bottom in a semicircle and emerges again at the top in the other semicircle of the same spaces. The cold air enters the one in between from above lying at the top open spaces and in the other semicircle of the same spaces at the bottom heated out.

Der schraubgenförmige Durchfluß von Kaltluft und Warmluft durch die Zwischenräume kann im Ausbau der Erfindung durch schraubenförmige, in den Zwischenräumen angeordnete Leitbleche unterstützt werden. Damit der Wärmeaustausch auf einem möglichst langem Weg erfolgt, ist der Wärmeaustauscher lang gebaut, das Verhältnis von Länge zu Breite soll größer als 1 sein.The helical flow of cold air and warm air through the intermediate spaces can be supported in the expansion of the invention by helical guide plates arranged in the intermediate spaces will. So that the heat exchange takes place over the longest possible path, the heat exchanger is built long, the ratio from length to width should be greater than 1.

zentrisch ineinander gestellte Rohre, 5, 6, 7, 8, 9 miteinander verbunden. Die zwischen den Rohren befindlichen Zwischenräume 10, 11, 12, 13 bzw. der Hohlraum 14 des innersten Rohres 9 sind unten abwechselnd mit den Halbringen 15, 16, 17, 18 bzw. der Halbkreisscheibe 19 und oben abwechselnd mit den Halbringen 20, 21, 22, 23 bzw. der Halbkreisscheibe 24 abgedeckt. Hierdurch wird die in die Kammer 1 eingeblasene kalte Luft gezwungen, in den Zwischenräumen 10, 12 und in dem Hohlraum 14 in einer Schraubenbewegung zur Ausblaskammer 3 zu fließen. In gleicher Weise wird die in die Kammer 2 eingeblasene Warmluft gezwungen, in den Zwischenräumen 11 und 13 in einer Schraubenbewegung zur Ausblaskammer 4 aufzusteigen. Hierbei findet an den Rohrwänden der Temperaturaustausch statt. Die Schraubenbewegung der Luft wird, in Figur 3 gezeigt, noch durch die in die Zwischenräume eingebauten Leitbleche 25 und 26 - der Übersichtlichkeit halber sind nur diese beiden eingezeichnet - unterstützt. centrally nested tubes 5, 6, 7, 8, 9 connected to one another. The spaces 10, 11, 12, 13 located between the tubes or the cavity 14 of the innermost tube 9 are alternating at the bottom with the half-rings 15, 16, 17, 18 or the semicircular disk 19 and at the top alternating with the half-rings 20, 21, 22, 23 or the semicircular disk 24 covered. As a result, the cold air blown into the chamber 1 is forced into the interstices 10, 12 and in the cavity 14 to flow in a screw movement to the blow-out chamber 3. In the same way, the in the chamber 2 blown warm air is forced to rise in the spaces 11 and 13 in a screw movement to the blow-out chamber 4. The temperature exchange takes place on the pipe walls. The helical movement of the air is shown in Figure 3, still through the baffles 25 and 26 built into the spaces - for the sake of clarity, only these two are shown - are supported.
