Process for reducing the levels of pollution from objects emitting noxious substances in indoor zones in which people spend time or work

摘要

For reducing levels of pollution within zones in which people spend time or work, frequented zones, with the air supply being introduced into the room at ceiling level, the air inside the room is first directed vertically downwards on the side facing the objects, is diverted by about 90@ in the floor area towards the frequented zone and in this zone is diverted by about 90@ vertically upwards into the ceiling area, in order to introduce the air there into the supply air fed to the room, thereby forming a circulation of air in the room.
