Abstract: An air diffuser for supplying air to a space is provided, the diffuser having a central axis, a plurality of discharge elements arranged to guide an air stream towards the space and defining a face of the diffuser and a plurality of channels located about the diffuser central axis, with each channel formed between adjacent pairs of discharge elements. An adjustment mechanism is also provided for adjusting a discharge direction of an air diffuser, as well as methods of forming the air diffusers and adjustment mechanisms hereof.

Abstract: The present invention relates to an air diffuser. The air diffuser comprises at least one primary discharge element. The secondary discharge element is arranged to discharge a secondary airstream capable of flowing across at least one surface that directs the secondary airstream substantially in a plane of the diffuser discharge face in the vicinity directly downstream of the secondary discharge element. The primary discharge element is arranged to discharge a primary airstream that is induced by the secondary discharged airstream such that the direction of the primary discharged airstream is largely determined by the direction of travel of the secondary airstream.

Abstract: An air diffuser for supplying air to a space, the diffuser having a central axis and comprising; a plurality of discharge elements arranged to guide an air stream towards the space, the plurality of discharge elements having respective edge regions that define a face of the diffuser; wherein a plurality of channels are located about the diffuser central axis, each channel being formed between adjacent pairs of discharge elements and configured to guide the air to the space. Wherein at least one of the discharge elements comprises a peripheral portion and a proximal portion relative to the central axis, and wherein the peripheral portion has a first air guide surface positioned at a first acute angle to the diffuser face, and the proximal portion has a second air guide surface positioned at a second acute angle to the diffuser face, the second angle being different to the first.

Abstract: An air diffuser comprising at least one discharge that is hand manipulable to vary at least two of the airflow rate, the airflow pattern and the airflow direction, wherein the airflow pattern produced by the discharge element may be at least one of a substantially perpendicular axial swirl pattern relative to the discharge element surface or a substantially inclined swirl pattern relative to the perpendicular axis of the discharge element surface.

Abstract: A method for delivering air comprising the steps of: discharging a first air stream, wherein the mass flow rate of first air stream can be varied; and discharging a second air stream, wherein the second air stream is arranged to induce the first air stream to deliver a combined air stream with a mass flow rate that can be varied.

Abstract: An air diffuser comprising a body, at least one swirl pattern discharge element and at least one jet pattern discharge element, wherein the jet pattern discharge element is manipulable to vary the airflow direction angle of a discharged jet pattern of air relative to an axis perpendicular to a discharge face of the swirl pattern discharge element to thereby alter the angle of the air discharged from the swirl pattern discharge element.
