Abstract
Ventilation system for ventilating especially classrooms (1) and similar rooms, comprising a lowered ceiling (3) and means, e.g. a ventilator (5), for forced air inlet from the outside air (6) into the room (2) above the lowered ceiling, and air outlet openings (7) mainly evenly spaced over the whole surface of the lowered ceiling. The exhaust air may be led via an HR unit (12-16) to preheat the supply air. Blowing the supply air along the underside of the concrete upper floor (4) enables cooling that floor at night. By day this cold may be used to cool the supply air.
Claims13
A method for ventilating rooms comprising:
- providing a surface structure parallel to a wall, ceiling or floor of a room;
- providing forced air inlet from the outside air into the room between said surface structure and said wall, ceiling or floor;
- providing air outlet openings, evenly spaced over the whole surface of said surface structure, wherein the ratio between a pitch and a diameter of said outlet openings is between 6 and 20:1.
A ventilation system for ventilating rooms like classrooms and the like, comprising a surface structure extending parallel to a wall, ceiling or floor of that room, and means for forced air inlet from the outside air into the room between said surface structure and said wall, ceiling or floor, and air outlet openings evenly spaced over the whole surface of the surface structure, wherein the ratio between a pitch and a diameter of said outlet openings is between 6 and 20:1.
