How do diffusers differ in their performance as air supply outlets?
The primary difference between various diffuser models lies in the characteristics (direction and potential for adjustment) of the supply air emitted into the conditioned space, and the location of the diffuser. Diffusers are typically installed in raised floor panels, although other configurations include desk-based and partition-based. The discussion below focuses on floor diffusers. Swirl floor diffuser: This is the most commonly installed type of diffuser in UFAD systems; more models are commercially available than any other design. The swirling air flow pattern of air discharged from this round floor diffuser provides rapid mixing of supply air with the room air in the occupied zone. Occupants do not have control over the direction of incoming air as it is always in the same swirling pattern. They do have limited control of the amount of air being delivered by rotating the face of the diffuser, or by opening the diffuser and adjusting a volume control damper. Constant velocity flo
