Abstract: A diffuser unit having a damper compartment with a plurality of damper apertures. The damper apertures are open or closed by respective damper doors to induce a swirl to air exiting the diffuser via an air deflector which may be a diffuser with diffuser blades or a perforated plate. Alternative embodiments relate to a method of diffusing an airflow and a method of determining an airflow rate for a diffuser unit.

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: 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: Disclosed herein is a diffuser module that can be used to air condition a space. The space may comprise the interior space(s) of buildings such as hospitals, enclosed shopping malls, warehouses, factories, etc. The module may comprise a body defining an interior chamber, the body having an upper end able to be connected to the air conditioning unit (AHU) and an opposing lower end. The module may also comprise a first channel disposed in the chamber for receiving a first air stream from the unit. The module may also comprise at least one diffuser connected to the lower end of the body, the at least one diffuser able to receive the first air stream from the first channel and discharge it to the space.

Abstract: In a method for operating a climate control system in a passenger compartment of a motor vehicle, the climate control system can be operated in a recirculation mode in which recirculated air is supplied to the passenger compartment or in fresh air mode in which at least a portion of the air supplied to the passenger compartment is fresh air. In its normal operating mode the climate control system is operated in recirculation mode. Upon exceeding a predetermined CO2-threshold value measured in the passenger compartment of the motor vehicle the climate control system is switched to fresh air mode.

Abstract: A motor vehicle interior is provided with a central jet located in a dashboard. An air state sensor located in the vehicle interior is subjected to the flow of air blown out of the central jet in the dashboard. The horizontal and vertical air guide systems are connected to one another by mechanical forced guidance to limit their movement possibilities so that they sweep a maximum blowing-out area that avoids the roof area provided with the air state sensor.
