摘要： A system for directing two separate streams of air to a commercial or industrial kitchen environment. The system includes a dual airflow plenum that is normally disposed adjacent a kitchen exhaust hood. Typically one stream of air is a tempered, that is heated or cooled, and is directed through the dual airflow plenum to where it is exhausted at an area or point adjacent the exhaust hood. A second untempered, that is ambient air, air stream is directed through the same dual air flow plenum and is exhausted into an area adjacent the exhaust hood. Preferably the plenum is positioned with respect to the exhaust hood such that the outlet for the untempered air is disposed generally between the exhaust hood and the outlet for the tempered air. Moreover, the relative velocity of the two air streams is maintained or controlled such that the velocity of the tempered air stream is equal to or greater than the velocity of the untempered air stream.
