Arrangement for ventilating a room, in particular a laboratory room

A configuration for ventilating a room having a passage region which is delimited at both sides by work tables, the configuration comprising:

• a supply air channel, disposed above the passage region, for supplying fresh air into the room, said supply air channel having first and second lateral air supply portions extending along the passage region and each having a plurality of circular air discharge openings formed therein from which a supply air is laterally discharged in a direction of the work tables, said supply air channel further having a substantially air-tight central partition portion and separates said first and second lateral air supply portion from each other;
• and
• a discharge air channel disposed there-above for discharging discharge air from the room, said discharge air channel having two slot-shaped suction openings formed therein and extending substantially parallel with said supply air channel and disposed in a region of a ceiling of the room such that at both sides of the passage region there is formed an air roll by means of which the supply air which is heated in a region of the work tables moves in a vertical direction into the region of the ceiling of the room.
