ABSTRACT:
An improved variable air volume air distribution system for distributing air within the interior of a building. The variable air volume air distribution system includes an air supply plenum, a supply fan for transferring air from the air supply plenum into the interior of the building, a return air plenum for receiving air from the conditioned space of the building, and an exhaust fan for exhausting air from the return air plenum to the outside atmosphere. The improvement includes a first pressure sensor located in the air supply plenum for sensing the air pressure within the air supply plenum; a second pressure sensor located in the return air plenum for sensing the air pressure within the return air plenum; and control structure for causing the exhaust fan to exhaust air from the return air plenum at a rate proportional to the ratio of the air pressure within the air supply plenum and the return air plenum.
