ABSTRACT:
A system and method for efficiently and economically providing a sufficient number of air changes per hour to satisfy government recommended standards for proper ventilation of industrial manufacturing facilities. The system is applicable to a building, housing manufacturing facilities and forms an enclosure within the building including the ceiling, floor and certain walls. The ventilation system may include an air-impervious curtain attached to the ceiling and to one or more walls, with a lower edge spaced above the floor to form the enclosure; and includes further an air supply assembly including ceiling mounted fans, vertical and horizontal ductwork for forcing outside unconditioned air into the enclosure at appropriate air flow rates and through a discharge slot formed in the horizontal ductwork at a level spaced above the floor, generally equal the height of the curtain lower edge above the floor; air heating units mounted within the building for forcing heated air from exterior the building into the enclosure; a plurality of ceiling mounted fans for withdrawing air trapped within the enclosure and exhausting it into the atmosphere; and a control unit for controlling the air supply assembly, the air heating units and the air exhaust fans for effecting a predetermined number of air changes within the enclosure.
