SETT OCH ANORDNINGAR FOR RENING AV LUFT I LUFTKONDITIONERINGS- OCH VENTILATIONSANLEGGNINGAR

摘要

Process for the cleaning of air in air-conditioning and ventilation systems comprises moistening the air by water, exposing the humidified air to ionisation and subsequently feeding the air to a washer 20. An apparatus for the performance of the process comprises an ionisation equipment (18) and/or an arrangement of ultra- violet tubes (19) downstream of a humidifying device, and upstream of a washer which operates either adiabatically or with cooled and cleaned water. The ionisation equipment may comprise an electrostatic precipitator.
