DEVICE FOR MOVING IONIZED AIR AND ITS DISTRIBUTION BY MEANS OF VENTILATION SYSTEM AND ELECTRIC FIELD Russian patent published in 2007 - IPC H01T19/00 A61N1/44 F24F3/16 

FIELD: creating indoor climate in industrial, medical, farming, and other premises where ionized air is needed.

SUBSTANCE: proposed device has DC voltage supply provided with two negative DC voltage leads and three positive leads placed at different voltage levels; three insulated anodes connected through screened conductors to three positive leads and disposed in three sections where negative air ions are required; anode disposed within indoor metal piece of equipment provided with air vents, each of insulated anodes being disposed in respective section and shaped so that negatively charged air ions are distributed throughout entire surface area of this section; isolated cathode disposed in section wherein air ions are undesirable; insulated accelerating/guiding ungrounded cathodes disposed at outputs of metal and nonmetal pipe connections of metal air conduit and connected through screened conductor to ungrounded negative lead of high-level DC voltage supply. Ungrounded cathodes are disposed in such manner and are so shaped that they can adequately vary flow of air and air ions; ungrounded cathodes are made of metal covered with dielectric coating and provided with air-passing holes. Metal air conduit and pipe connection, conducting coating of nonmetal pipe connection, indoor metal equipment, isolated cathode, screen of conductor running to ungrounded cathodes, and screens of conductors running to three anodes are interconnected by means of conductor connected to grounded negative lead of lower-level DC voltage supply. Air conduit accommodates air flow creating fan and negatively charged air ion supply insulated from air conduit. In addition, polarity of DC voltage supply leads varies during bipolar ionization with change in polarity of air ions generated by air ion supply; synchronizing coupling is provided between air ion supply and DC voltage supply to ensure in-step variation of voltage polarities.

EFFECT: enlarged functional capabilities and enhanced effectiveness of device.
