Patent ID: 7568360

Claim:
A system for reducing effects of adverse air re-circulation in a room containing at least one heat generating component, said system comprising: an air conditioning unit configured to cool airflow in the room; at least one cooling vent tile operable to deliver the cooled airflow to the at least one heat generating component; at least one secondary vent tile positioned and operated to one of, introduce airflow into a re-circulating airflow and remove airflow from a re-circulating airflow, to thereby respectively divert or vary the temperature of the re-circulating airflow and thereby reduce the effects of air re-circulation in the room; a plurality of airflow detection devices positioned at a plurality of locations in the room; and a controller configured to receive information regarding airflow at the plurality of locations in the room from the plurality of airflow detection devices, said controller being configured to evaluate the received information to determine whether and where airflow re-circulation is occurring in the room, and wherein the controller is further configured to control the at least one secondary vent tile based upon the determination independently from the at least one cooling vent tile.
