Abstract
An air handling unit includes a manifold having an inlet configured to receive a supply of air, a plurality of apertures formed in the manifold, the apertures enabling a passage of air from the manifold out of said the handling unit, a bypass plenum formed in the manifold, and a damper positioned within the bypass plenum. The damper is pivotable between a closed position and an open position to allow air from the manifold to exit the air handling unit without passing through the apertures when a pressure within the manifold exceeds a threshold pressure.
Claims17
An air handling unit, comprising:
- a manifold having an inlet configured to receive a supply of air;
- a plurality of apertures formed in said manifold, said apertures enabling a passage of air from said manifold out of said air handling unit;
- a bypass plenum formed in said manifold;
- and
- a damper positioned within said bypass plenum, said damper being pivotable between a closed position and an open position to allow said air from said manifold to exit said air handling unit without passing through said apertures when a pressure applied to said damper exceeds a threshold pressure;
- and
- wherein said bypass plenum is oriented at a distal end of said manifold such that said air exiting said manifold via said bypass plenum is not constrained by said air exiting said manifold via said apertures.
A method for controlling a flow of a fluid in an air handling unit, comprising the steps of:
- providing a supply of air to a manifold of said air handling unit;
- permitting passage of said supply of air from said manifold out of said air handling unit and into a room environment to be conditioned, through a plurality of apertures in said manifold;
- when a pressure applied to a damper associated with a bypass plenum within said manifold exceeds a threshold pressure, opening said damper to allow a portion of said supply of air to exit said manifold without passing through said apertures;
- and
- positioning said bypass damper at a distal end of said manifold so as to be not surrounded by said apertures.
An air handling unit, comprising:
- a manifold having an inlet configured to receive a supply of air;
- a plurality of apertures formed in said manifold, said apertures being formed along opposing lateral edges of said manifold and enabling a passage of air from said manifold and out of said air handling unit into an environmental space that is to be conditioned;
- a bypass plenum formed in said manifold, said bypass plenum being positioned adjacent to but not between said apertures formed on said opposing lateral edges;
- and
- a damper positioned within said bypass plenum, said damper being selectively operable to allow a variable amount of said air from said manifold to exit said bypass plenum without passing through said apertures.
