Abstract
A thermally powered change-over diffuser is disclosed which includes a housing having an outlet and movable blade assembly mounted with respect to the outlet for displacement between a first position producing a Coanda flow across a surface, such as a ceiling, and a second position producing a detached stream in a generally normally extending direction with respect to the surface. The diffuser is preferably thermally powered and includes a rapid change-over assembly enabling substantially immediate shifting between the two positions so as to provide a cooling mode of discharge and heating mode of discharge. Additionally, means for adjusting the volume of air discharged is provided.
