Luftionen in Gebäuden – elektroionisches Mikroklima
10.1002/bapi.200610026.abs
Im atmosphärischen elektrischen Feld der Erde werden Luftionen gebildet, sie sind Bestandteil der Umwelt. Der Mensch ist ihnen ausgesetzt und sein Allgemeinbefinden wird von ihnen beeinflußt. Der Beitrag beschreibt die elektrostatischen Eigenschaften der Raumluft und ihre Auswirkungen auf den Menschen sowie die Funktionsweisen von Luftionisatoren.
Air ionization and indoor climate.
Positive and negative ions are produced in the air by the impact of the electric field between earth and ionosphere, by UV and cosmic radiation and by so called Lenard effect. The created electrically charged particles (ions) are not stable and join together with neutral atoms and molecules into the complexes of 10 to 30 molecules being already stable and called “lightweight ions” or “aeroions”. In an interior the aeroion creation is impacted by the external walls (classic materials as wood and bricks are optimal), by air‐handling systems (aeroions are discharged at the metal parts of the system), by indoor equipment (e.g., raw wood without surface finish neutralizes a considerable aeroion quantity by its surface) and by human activities: just one smoked cigarette liquidates practically all aeroions in the room. The aeroions are the catalyzers of human body biochemical reactions and affects the nervous system total condition. Finally principles of the most often used ionizers are presented, especially hydrodynamic and with corona charge.
