Title Artificial ionisation of pure room air
Original title Iskusstvennaja ionizacija čistogo vozduha pomeščenij [in Russian]
Bibliographic information 1982, No.6, p.19-21. Illus. 9 ref.
Abstract Removal of undesirable materials from air also removes air ions, which apparently adversely affects the well-being of workers in places supplied with purified air. Measurements showed that placement of a separate air ioniser in a room does not provide a dependable or uniform distribution of air ions throughout the room. Placement of a 2-electrode system in the air supply duct of the experimental room gave better distribution of the ions. The use of 2 electrodes facilitates maintenance of the proper concentration of ions: pointed corona-discharge electrodes are mounted upstream in the air duct and connected with the negative pole of a direct-current source (-5000V), and a mesh electrode is mounted downstream and connected with the positive pole of a variable direct-current source (0-2700V); the potential on the positive electrode is varied as necessary to obtain proper ion levels in the room air, as measured with an appropriate ion counter.
