Air conditioning element (1) of a woven or non-woven fabric comprises a wall provided with at least a first array of through holes (21) for distributing air, wherein the following relations apply to the through holes (21) constituting said first array: the twofold value of the square root of the quotient between the value of the inlet area (S) of a through hole (21) and the value π is less than or equal to the value of the wall thickness of the element (1) in the region adjacent to said through hole (21) and the centre line (O1) of the through hole (21) intersects the inlet plane of said through hole (21) at an angle α=60° through 89°, more preferably 80° through 88°, most preferably 83° through 87°. |
