Definitions

  • the invention relates to an air conditioning duct that is bactericidal and fungicidal. Air ducts with such an inner surface are often used in ventilation and air conditioning systems.
  • JP-A-59124428 shows an air conditioning system in which individual device parts and an air duct section which accommodates such device parts are provided with a coating which consists of a fungicide.
  • a trichlorohydroxyziphenyl ether is used as the chemical substance for the fungicidal coating; This is a toxic chemical, by means of which fungi, germs etc. contained in the air passing through the air conditioning system are killed. The killing takes place due to the high toxic effect of the chemical substance.
  • the invention has for its object to provide a bactericidal and fungicidal climate channel.
  • the air conditioning duct has strongly alkaline and strongly acidic areas. Due to the creation of a strongly alkaline and a strongly acidic chemical environment within the climate channel, fungus-like growths, which are known as disease carriers, are prevented from developing within the climate channel. The strong alkaline and the strongly acidic chemical milieu is used to kill the bacteria, fungi, germs etc.
  • the strongly alkaline / strongly acidic interaction prevents to a large extent the growth of fungi and bacteria, as well as viral loads in the climate channel.
  • a strongly alkaline or an alternately strongly alkaline and strongly acidic air conditioning duct can be produced in a particularly simple manner if its inner skin is designed as a hose which is exchangeable and alternately consists of a strongly alkaline and a strongly acidic material.
  • a particularly frequent and effective change between strongly acidic and strongly alkaline chemical milieu results when the inner surface of the air conditioning duct alternates with successively strongly alkaline and strongly acidic stripes. This makes the formation and multiplication of pests particularly effective, e.g. Viruses, bacteria etc. prevented.
  • An inner surface provided with successive strips in this way can be created in a particularly simple manner by applying strongly acidic strips to a strongly alkaline lower surface at a distance from one another or strongly alkaline strips to a strongly acidic lower surface.
  • perforated inserts that are offset one above the other and of which one perforated insert consists of a strongly alkaline material and the other perforated insert consists of a strongly acidic material.
  • a perforated insert configured in this way as a film can be inserted into the air conditioning duct as a one-piece pipe system or as a perforated pipe system.
  • the air conditioning ducts according to the invention can advantageously be used for the production of ventilation and air conditioning systems.

Abstract

Une gaine d'aération ou de climatisation pour un dispositif de ventilation présente une surface conçue pour avoir une action bactéricide ou fongicide. Cette configuration permet un traitement biochimique de l'air circulant dans les gaines. Pour améliorer encore l'action biochimique, il est proposé que la surface intérieure présente, dans le sens de circulation de l'air, des sections striées alternées et séparées, dont les unes sont conçues pour être fortement alcalines et les autres fortement acides.

Claims (7)

  1. Conduit de climatisation, traité fongicide et bactéricide, caractérisé en ce que ce conduit de climatisation présente des zones fortement alcalines et des zones fortement acides.
  2. Conduit de climatisation conforme à la revendication 1, dont l'enveloppe interne est un tube souple qui est remplaçable et qui est constitué d'un matériau fortement alcalin et d'un matériau fortement acide, disposés en alternance.
  3. Conduit de climatisation conforme à la revendication 1 ou 2, dont la surface interne présente des bandes successives tour à tour fortement alcalines et fortement acides.
  4. Conduit de climatisation conforme à la revendication 3, dans lequel sont disposées, sur une surface de base fortement alcaline, des bandes fortement acides, à une certaine distance l'une de l'autre, ou bien, sur une surface de base fortement acide, des bandes fortement alcalines, à une certaine distance l'une de l'autre.
  5. Conduit de climatisation conforme à la revendication 3 ou 4, dans lequel au moins l'une des bandes successives tour à tour fortement alcalines et fortement acides présente un rétrécissement de la section d'écoulement, à peu près en forme d'entonnoir.
  6. Conduit de climatisation conforme à la revendication 1 ou 2, dans lequel des éléments de garniture perforés, en métal ou en matière plastique, sont disposés l'un sur l'autre en décalage, et l'un de ces éléments est en un matériau fortement alcalin et l'autre en un matériau fortement acide.
  7. Conduit de climatisation conforme à l'une des revendications 1 à 6, caractérisé en ce qu'on l'emploie pour fabriquer une installation d'aération et de climatisation.
