Method and apparatus for air purification in confined spaces, useful for reducing content of germs and volatile organic compounds, comprises controlled introduction of ozone and oxygen ions

摘要

Method, and arrangement of system components, for (a) reducing germ and VOC (volatile organic compounds) load in the air or on the surfaces in a room, or in associated ventilation systems and (b) for maintaining a natural ratio of oxygen ions (small ions) (A) and ozone (B) in the room. Method, and arrangement of system components, for (a) reducing germ and VOC (volatile organic compounds) load in the air or on the surfaces in a room, or in associated ventilation systems and (b) for maintaining a natural ratio of oxygen ions (small ions) (A) and ozone (B) in the room. The method comprises introducing into the room (A) at a maximum of 10 4 ions/cm 3 and (B) at a maximum of 30 ppb (60 mu g/cm 3). (A) and (B) are generated by a combined ion/ozone generating apparatus, placed in the room and either integrated or incorporated into the air circulation, and then they are introduced into the room through the air supply, the central aeration unit or the air recirculation system.
