Description

Befeuchtungswärmetauscher Befeuchtungswärmetauscher

Die Erfindung betrifft einen Befeuchtungswärmetauscher.The invention relates to a humidifying heat exchanger.

Befeuchtungswärmetauscher werden für verschiedene Zwecke verwendet, beispielsweise für Wasseraufbereitungsanlagen zur Verbesserung deren Wirkungsgrad und für Klimaanlagen.Humidification heat exchangers are used for various purposes, such as for water treatment plants to improve their efficiency and for air conditioning.

Aus der EP 1 710 516 Bl sind eine Vorrichtung und ein Verfahren zur Befeuchtung eines Luftstroms bekannt, aus der US 2004/0003619 Al ein Verfahren zum Verbessern der Benetzbarkeit der Oberfläche von Wärmetauschern.From EP 1 710 516 B1 an apparatus and a method for humidifying an air flow are known, from US 2004/0003619 A1 a method for improving the wettability of the surface of heat exchangers.

Der Erfindung liegt die Aufgabe zugrunde, einen Befeuchtungswärmetauscher zu schaffen, der bei einfachem Aufbau einen hohen Energie- und Stoffaustausch ermöglicht.The invention has for its object to provide a humidifying heat exchanger, which allows a high energy and mass transfer with a simple structure.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Befeuchtungswärmetauscher versehen ist mit einem Gehäuse, einem in das Gehäuse eingebauten, von unten nach oben von einem Medium durchströmten Wärmetauscherelement, auf das Wärmetauscherelement sich vertikal erstreckend aufgefädeltes Befeuchtermaterial, und einem über dem mit dem Befeuchtermaterial versehenen Wärmetauscher angeordneten, das Befeuchtermaterial benetzenden Wasserverteiler, wobei die von oben nach unten durch das Gehäuse strömende Luft befeuchtet und gemeinsam mit dem im Gleichstrom durch das Gehäuse an dem Befeuchtermaterial herab rieselnde Wasser von dem den Wärmetauscher durchströmenden Medium erwärmt wird.According to the invention this object is achieved in that the Befeuchtungswärmetauscher is provided with a housing, built into the housing, from bottom to top of a medium flowed through the heat exchanger element, on the heat exchanger element vertically extending aufgefädeltes humidifier, and one above the provided with the humidifier heat exchanger arranged, the humidifier wetting wetted water distributor, wherein the air flowing from top to bottom through the housing humidifies and is heated together with the co-current through the housing on the humidifier trickling down water from the medium flowing through the heat exchanger.

Anspruch 2 gibt eine bevorzugte Ausgestaltung an.Claim 2 indicates a preferred embodiment.

Die Erfindung wird im Folgenden anhand einer Zeichnung erläutert.The invention will be explained below with reference to a drawing.

Der Befeuchtungswärmetauscher besteht aus einem Gehäuse 3, einem in das Gehäuse 3 eingebauten Wärmetauscherelement 1, bei dem es sich vorzugsweise um einen Rohrbündelwärmetauscher handelt und das von unten nach oben von einem Heizmedium durchströmt wird. Auf dem Wärmetauscherelement 1 ist ein Befeuchtermaterial 5 aufgefädelt, das sich im Wesentlichen vertikal erstreckt. Über dem mit dem Befeuchtermaterial 5 versehenen Wärmetauscherelement 1 ist ein Wasserverteiler 6 angeordnet, der mit Löchern versehen ist, die ein Wässern des Befeuchtermaterials 5, bewirken.The humidification heat exchanger consists of a housing 3, a built-in the housing 3 heat exchanger element 1, which is preferably a Is tubular heat exchanger and flows through from bottom to top of a heating medium. On the heat exchanger element 1, a humidifier 5 is threaded, which extends substantially vertically. Above the humidifier material 5 provided with the heat exchanger element 1, a water distributor 6 is arranged, which is provided with holes, which cause a wetting of the humidifier 5 ,.

Von einem - nicht dargestellten — Gebläse wird Luft oben in das Gehäuse eingeführt und unten abgezogen.From a - blower - not shown - air is introduced into the top of the housing and pulled down.

Bei diesem Anwendungsfall wird das an dem Befeuchtermaterial 5 herab rieselnde Wasser zum Teil verdunsten, die Luftfeuchtigkeit der im Gleichstrom mit dem herab rieselnden Wasser durch das Gehäuse strömenden Luft wird zunehmen, wobei sowohl das Wasser als auch die Luft durch das in dem Wärmetauscherelement 1 im Gegenstrom strömende Medium erwärmt werden (bei Verwendung dieses Befeuchtungswärmetauschers als Klimaanlage wird das in dem Wärmetauscherelement 1 strömende Medium entsprechend gekühlt werden). In this case, the water trickling down on the humidifying material 5 will partially evaporate, and the air humidity of the air flowing through the casing in cocurrent with the trickling water will increase, with both the water and the air in countercurrent flow through the heat exchanger element 1 flowing medium to be heated (when using this humidification heat exchanger as the air conditioner, the medium flowing in the heat exchanger element 1 will be cooled accordingly).
