ABSTRACT:
A diffuser introduces air into a conditioned space to obtain a desired indoor atmospheric environment. The diffuser has a diffuser body and an inlet through the diffuser body. The inlet has an inlet area to receive the air within the diffuser. The diffuser has a primary outlet through the diffuser body. The primary outlet has a fixed primary area to direct air from within the diffuser into the conditioned space. The diffuser has a secondary outlet through the diffuser body. The secondary outlet is provided to direct the air from within the diffuser into the conditioned space. The secondary outlet has a secondary area that is adjustable in size between a predetermined minimum secondary area and a predetermined maximum secondary area. The predetermined minimum area may be chosen to be zero to provide for a fully closed secondary outlet when the secondary area is adjusted to its minimum area. The diffuser may be implemented with a plurality of primary outlets and a plurality of secondary outlets.
