Normally we supply fresh air to a room with a diffuser, and this air is distributed in the room according to different principles as: mixing ventilation, displacement ventilation etc. That means we have to supply a very large amount of air to the whole room, although a person in the room totally only need a small amount of air. It is usual to supply 1-5 times the volume of the room per hour, but a person only need (in his/her inhalation) about 0.6 m3 per hour. Therefore, if people have a rather fixed position during the work, there is a possibility to supply air more directly to the breathing zone, and therefore to supply a much smaller amount.
