Definitions

  • the present invention relates to in duct ionization systems. More specifically, the present invention relates to an in duct ionization system with an insulated access door.
  • indoor air environments frequently include suspended particulates, such as dust, dander, soot and smoke particles, pollen, mold, bacteria, and viruses.
  • Indoor gases are also present, being released from building materials, home furnishings and nondurable goods.
  • the greater user of machines, such as photocopying equipment and the like, is especially problematic, as this equipment may emit volatile organic compounds.
  • HVAC heating, ventilation and cooling
  • traditional filters are only effective for large particles of at least 10 microns in size.
  • high efficiency particle air (HEPA) filters are more effective, they also have disadvantages, as they may quickly become clogged, requiring frequent changing to avoid overburdening the HVAC equipment. Because of the presence of contaminants in the air and the general inability of physical filters to remove the same, a condition known as "sick building syndrome" has developed.
  • An alternative method to filtering involves the use of ion exchange technology to remove contaminants from air. Ionization occurs where an atom or group of atoms loses or gains one or more electrons. An electrically neutral atom or molecule will have an equal number of electrons and protons, if an electron bound to an atom or molecule absorbs enough energy from an external source, it may exceed the ionization potential and allow the electron to escape its atomic orbital. When this occurs, the electron is lost, and an ion with a positive electrical charge, a cation, is produced. Electrons that are lost become free electrons. When a free electron later collides with an atom, it may be captured within an orbital. The gain of an electron by an atom or molecule creates an ion with a negative electrical charge, an anion.

Abstract

L'invention porte sur un dispositif et sur un procédé qui mettent en œuvre un système d'ionisation pour purifier de l'air s'écoulant à l'intérieur d'un conduit. Le système comprend un cadre conçu pour être attaché au conduit et comprenant au moins un élément de verrouillage. Un panneau isolé est conçu pour être reçu par le cadre dans une relation d'ajustement étroit, et comprend au moins un élément de contre-verrouillage qui coopère avec le ou les éléments de verrouillage. Un tube d'ionisation vient en prise de façon amovible avec la surface interne du panneau isolé afin d'être placé à l'intérieur du conduit. Le remplacement des tubes d'ionisation selon la présente invention est simplifié par rapport à l'état de la technique des systèmes d'ionisation dans un conduit.
