Abstract
An air conditioning element of a woven or non-woven fabric includes a wall provided with at least a first array of through holes for distributing air, wherein the following relations apply to the through holes constituting the first array: the twofold value of the square root of the quotient between the value of the inlet area of a through hole and the value π is less than or equal to the value of the wall thickness of the element in the region adjacent to the through hole and the center line of the through hole intersects the inlet plane of the through hole at an angle α=60° through 89°, more preferably 80° through 88°, most preferably 83° through 87°.
Claims12
An air conditioning element made of a woven or non-woven fabric comprising:
- a wall having at least a first array of through holes therein for distributing air, the through holes having side walls, each through hole has a diameter in the range of 0.20 mm and 0.60 mm,
- wherein the following relations apply to the through holes in the wall constituting the first array:
- a twofold value of the square root of the quotient between a value of an inlet area of the through hole and the value π is less than or equal to a value of a wall thickness of the element in a region adjacent to said through hole, and
- a centre line of the through hole intersects an inlet plane of the through hole at an angle α between 60° and 89°.
