Abstract

Air ducts and air-conditioning ducts for ventilation systems have a surface designed to have a bactericidal and fungicidal action. This design results in the air flowing through the air duct being subjected to a chemical treatment. In order to improve the chemical action, the invention proposes that the internal surface of the duct has strongly alkaline and strongly acidic sections which alternate in separate zones along the duct in the direction of flow of the air.

Description

ßakterizides und funσizides Material zum Herstellen von Klimakanälen ' Bactericidal and funicicidal material for the production of climate channels'
Es ist bekannt, daß in Klimakanälen pilzartige Wucherungen entstehen, die als Krankheitsträger bekannt sind.It is known that fungal growths, which are known as disease carriers, occur in climate channels.
Es wird daher erfindungsgemäß vorgeschlagen, die Luftkanäle hinter den Klimaanlagen bakterizid und fungizid auszubilden in der Form, daß die Kanäle in bestimmten Bereichen stark alkalisch, in anderen Bereichen wieder stark sauer ausgebildet sind, so daß durch die Wechselwirkung von stark alkalisch und stark sauer Wucherungen von Pilzen und Anla¬ gerungen von Bakterien sowie virenähnliche Bela¬ stungen vermieden werden.It is therefore proposed according to the invention to design the air ducts behind the air conditioning systems to be bactericidal and fungicidal in such a way that the ducts are strongly alkaline in certain areas and strongly acidic in other areas, so that the interaction of strongly alkaline and strongly acidic growths of Fungi and deposits of bacteria as well as virus-like contamination can be avoided.
Es wird weiterhin erfindungsgemäß vorgeschlagen, daß schlauchförmige Körper, geschlossen oder auch gelocht, vorzugsweise mit unterschiedlichen pH- Werten, d.h. stark sauer und stark alkalisch, übereinander in den Kanal eingezogen werden und somit einen Schädlingsbefall verhindern. Selbstverständlich kann das Material selber auch lochförmigen Charakter aufweisen und z.B. stark alkalisch sein oder stark sauer, und die eingelegte Folie kann als Einstückrohrsystem oder auch als perforiertes Rohrsystem den gegenläufigen pH-Wert oder auch den gleichwertigen pH-Wert haben, wobei es darauf ankommt, in welcher Gegend der Welt die Belüftungs- und/oder Klimaanlagen-Technik einge¬ setzt wird, und hier stellt sich dann die Frage, welche Bakterien- und Pilzkulturen fallen bei welchem pH-Wert in der vorgegebenen Gegend an.It is further proposed according to the invention that tubular bodies, closed or perforated, preferably with different pH values, ie strongly acidic and strongly alkaline, are drawn into the channel one above the other and thus prevent pest infestation. Of course, the material itself can also have a hole-like character and, for example, be strongly alkaline or strongly acidic, and the inserted film, as a one-piece pipe system or as a perforated pipe system, can have the opposite pH value or the equivalent pH value, which depends on Which area of the world the ventilation and / or air conditioning technology is used for, and then the question arises as to which bacterial and fungal cultures occur at which pH in the given area.
Der erEindungsgeraäße Gedanke der starken Alkalität und/oder der Wechselwirkung von stark alkalisch nach stark sauer und das Übereinanderlagern von verschiedenen Materialien oder das Hintereinan- deranordnen von verschiedenen Materialien, vorzugs¬ weise in Streifenform, sprich Zebra-Form, unterbin¬ den erfindungsgemäß die Bildung von Wachstumsmög¬ lichkeiten bei Mensch, Tier und Pflanze von sich bildenden und/oder vermehrenden Schädlingen, wie z.B. Bakterien, Viren etc..The inventive idea of strong alkalinity and / or the interaction from strongly alkaline to strongly acidic and the superimposition of different materials or the arrangement of different materials one behind the other, preferably in the form of strips, ie zebra form, prevent the formation of Possibilities for growth in humans, animals and plants of developing and / or multiplying pests, such as, for example Bacteria, viruses etc.
Durch eine eine schwach trichterförmige Strömungsquer¬ schnittsverengung bewirkende körperliche Ausgestaltung der im Kanal angeordneten stark sauren und/oder stark alkalischer Streifen kann eine gute Durch- mischung der Luftströmung bewirkt werden, wodurch die gesamte durchströmende Luft mit' dem Wechsel alkalisch/ sauer beaufschlagt wird. Through a physical configuration causing a slightly funnel-shaped flow cross-sectional constriction The strongly acidic and / or strongly alkaline strips arranged in the duct can cause a thorough mixing of the air flow, as a result of which the entire air flowing through is acted upon by the change from alkaline to acid.
