Abstract

The heat exchanger comprises heat exchanger main portion having a surface that is made of plastic and is treated with fluorine for enhancing the drainage of condensed liquid. The heat exchanger material is washed and treated with water to avoid contamination.

Description

Stand der TechnikState of the art

Die Erfindung betrifft eine Fluorbehandlung von solchen Luft-Luft-Wärmetauschern aus Kunststoff, bei denen vor allem in der Wohnungslüftung das Ablaufverhalten von Kondensat verbessert werden soll.The invention relates to a fluorine treatment of such air-to-air heat exchangers made of plastic, in which the drainage behavior of condensate should be improved, especially in the home ventilation.

Derzeit ist eine industrielle Fluorierung solcher Wärmetauscher für ein verbessertes Ablaufverhalten nicht bekannt.At present, industrial fluorination of such heat exchangers is not known for improved drainage performance.

In Einzelanwendungen wurde die Wärmetauscheroberfläche durch Auftrag von Hydrophobierungsmitteln derart modifiziert, dass sich verstärkt Tropfen bildeten. Da aber bei solchen Tropfen die Adhäsionskräfte zwischen Tropfen und Oberfläche zu stark sind, ist kein verbesserter Wasserablauf zu erreichen.In individual applications, the heat exchanger surface was modified by application of hydrophobing agents in such a way that droplets were increasingly formed. However, since the adhesion forces between the drops and the surface are too strong in such drops, no improved water flow can be achieved.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es, das Ablaufverhalten auf der Kunststoffoberfläche durch eine flache Filmbildung zu verbessern.The object of the invention is to improve the flow behavior on the plastic surface by a flat film formation.

Gegenstand und Vorteile der ErfindungSubject and advantages of the invention

Zur Lösung der Aufgabe wird die Kunststoffoberfläche mit Fluor behandelt. Dazu wird der Wärmetauscher in Teilen oder als Ganzes in eine mit Fluorgas gesättigte Kammer für eine bestimmte Zeit verbracht.To solve the problem, the plastic surface is treated with fluorine. For this purpose, the heat exchanger is spent in parts or as a whole in a saturated with fluorine gas chamber for a certain time.

Um ein Abwaschen von Fluorrückständen und eine Verunreinigung des Kondensates beim regulären Einsatz z. B. in einem Wärmerückgewinnungsgerät für die Wohnungslüftung zu vermeiden, wird der Wärmetauscher werksseitig nach dem Fluorieren mit einem Medium (bevorzugt Wasser) gewaschen.To wash off fluorine residues and contamination of the condensate during regular use z. B. in a heat recovery device for home ventilation, the heat exchanger is factory-washed after fluorination with a medium (preferably water).
