Abstract: Air-conditioning diffuser for distributing air, comprising a chamber (10) provided with an inlet orifice (30) for feeding air and with an outlet wall (20) made of a woven or non-woven fabric or foil, the outlet wall (20) comprising at least one array of through-holes (22) for distributing air into the surrounding environment. The air-conditioning diffuser further comprises a plurality of air deflecting pockets (23) for redirecting the air flowing through the through-holes (22) out of the air-conditioning diffuser, each air deflecting pocket (23) being attached to the outlet wall (20) on the outer side of the same, overlapping at least one through-hole (22) spaced apart from the through-hole and being open towards the space adjoining the outlet wall (20).

Abstract: An air-conditioning duct comprises a regulating membrane attached to a peripheral wall of the duct and a shifting element. The membrane has a first end that is attached to the shifting element and faces an inlet for supplying air. An area of the membrane comprising said first end is adapted for being selectively shifted to a first or second portion of the peripheral wall. The shifting element is for shifting the first end of the membrane to the first or second portion of the peripheral wall. The membrane has a second end, which faces away from the inlet of the duct, secured inside the duct to ensure that shifting of the area of the first end of the membrane to the second portion of the peripheral wall prevents the air flow from passing through that portion of the duct situated downstream of the attached second end of the membrane.

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 ? 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 ?=60° through 89°, more preferably 80° through 88°, most preferably 83° through 87°.

Abstract: 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 ? 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 ?=60° through 89°, more preferably 80° through 88°, most preferably 83° through 87°.
