Abstract:
An air conditioning unit mounting curb adapted for flat roof-top mounting with provisions for ducts for passage of air to and from an air conditioning unit from and to a plurality of rooms immediately subadjacent and spaced below the roof top. The mounting curb is comprised of a rectangular outer perimeter, a closed bottom, a wall dividing the curb into two plenums, and at least one opening in one of the plenums for supply of air to the rooms and at least one opening in the second plenum for return air from said rooms. The improvement in the mounting curb comprises a bypass means between the plenums, which is responsive to pressure differential acting thereon, providing a variable air volume system. The bypass means consists of an opening in the dividing wall, a damper blade covering the opening and hingeably connected to the return air side of the dividing wall, a lever attached at one end to the damper blade and at the opposite end thereof to an axle rod, which extends through the curb. An adjustable counterweight is provided on the end of the rod to yieldably maintain the damper blade in the closed position.
