Swirl diffusers
Diffusers are very common in heating, ventilating, and air-conditioning systems. Diffusers are used on both all-air and air-water HVAC systems, as part of room air distribution subsystems, and serve several purposes:
1) To deliver both conditioning and ventilating air
2) Evenly distribute the flow of air, in the desired directions
3) To enhance mixing of room air into the primary air being discharged
4) Often to cause the air jet(s) to attach to a ceiling or other surface (Coandă effect)
5) To create low-velocity air movement in the occupied portion of room
6) Accomplish the above while producing the minimum amount of noise
When possible, dampers, extractors, and other flow control devices should not be placed near diffusers inlets (necks); either not being used at all or being placed far upstream. They have been shown to dramatically increase noise production. For as-cataloged diffuser performance, a straight section of duct needs serve a diffuser. An elbow, or kinked flex duct, just before a diffuser often leads to poor air distribution and increased noise.
