<p>The ventilation system for an office etc. uses an underfloor distribution system which can be used with a distributor which forms an air curtain over a window adjacent to the office area. The second distributor has an outlet grid level with the window sill, and fresh air can be drawn in under the sill. The changeover between the two flows is controlled by a cylindrical distributor, with a control flap altered automatically at the same time near floor level. An alternative design uses a distributor unit level with the window and collector ducts in the ceiling and also behind the unit.</p> |
