LAMINAR AIRFLOW DIFFUSER

摘要

LAMINAR AIRFLOW DIFFUSER A laminar airflow diffuser for directing air into a room and for distributing air into at least a portion of the room uniformly and vertically downwardly. The airflow diffuser includes a plenum positioned near the ceiling and having a chamber therein and an inlet opening which is connectable to an airflow source. The plenum opens downwardly, and the opening is covered by a perforated face plate. The airflow diffuser also includes a distribution baffle disposed within the plenum chamber and connected to the air inflow opening. The airflow diffuser is functional to distribute the air generally uniformly throughout the plenum chamber. The airflow diffuser also includes a planar distribution grid positioned above the perforated face plate to preclude horizontal airflow adjacent the perforated face plate, the distribution grid being formed by a plurality of intersecting narrow vertical vanes.
