Claim:
An improved air handling system for a building comprising: a base adapted for connection of said system to a building rooftop; at least two pedestal legs; two smooth exterior and opposing side walls of a planar, physically uninterrupted configuration such that there are no air vents, physical projections, or mechanical appurtenances therefrom; two exterior end walls wherein at least one of said end walls has louvers; a roof; a floor; an open floor frame; an exterior access door; a plurality of interior walls; at least one vertical up outlet fan; at least one supply fan unit comprised of a supply fan, a motor and a motor controller; at least one slant filter; and at least one slant cooling coil; wherein said base and said pedestal legs reside atop said building, and said side walls, said end walls, said floor, said floor frame and said roof are assembled so as to form a first generally cuboid air handling unit enclosure that resides atop and is supported by said base and said pedestal legs, and wherein said air handling unit enclosure's interior walls are arranged to form an intake room, a plenum room to selectively provide fresh air and return air to the fan room, a fan room to provide air to the building, an air rejection room to exhaust air, and an access corridor, wherein said access corridor shares a common wall with each of said intake room, said fan room, and said heat rejection room, and where said heat rejection room contains said rooftop mounted fan and said motor and has an open floor frame supported at a first end by said pedestal legs and at a second end by said base; and wherein said fan room contains at least one supply fan, and wherein said filter and said coil reside between said intake room and said fan room, wherein a plurality of interior access doors allow access to the intake room, the plenum room, the fan room from the access corridor, the access corridor being open to the heat rejection room, and wherein a damper in the plenum room allows airflow from the plenum room to the heat rejection room via the access corridor.
