Abstract
A linear bar diffuser includes a grille frame and blades in a stacked arrangement within the grille frame such that space is provided between adjacent blades to facilitate flow of an incoming air flow therethrough. One of the blades includes a leading edge configured to face the incoming air flow, the leading edge including an undulated contour extending along a length of the blade and into a width of the blade, the width of the blade extending transverse to the length and between the leading edge and a trailing edge of the blade.
Claims19
A linear bar diffuser comprising:
- a grille frame;
- a plurality of blades in an arrangement within the grille frame such that space is provided between adjacent blades of the plurality of blades to facilitate flow of an incoming air flow therethrough;
- and
- a blade of the plurality of blades including a leading edge configured to face the incoming air flow, the leading edge including an undulated contour extending along a length of the blade and into and out of a width of the blade, the width of the blade extending transverse to the length and between the leading edge and a trailing edge of the blade;
- wherein the blade comprises a wave shape extending along the length of the blade at a position along the width of the blade between the leading edge and the trailing edge, and wherein the wave shape and the undulated contour comprise corresponding curvatures into and out of the width of the blade.
A linear bar diffuser blade, comprising:
- a length configured to extend perpendicular to an air flow;
- a width configured to extend parallel to the air flow;
- a leading edge extending along the length of the linear bar diffuser blade, configured to face the air flow, and including an undulated contour, wherein the undulated contour includes peaks and valleys extending into and out of the width of the linear bar diffuser blade, wherein the peaks and valleys are joined such that the undulated contour forms a continuously smooth, wave-like curvature across the peaks and the valleys without a straight segment, without a sharp segment, without a jagged segment, and without a saw-like segment;
- and
- a wave shape extending along the length of the linear bar diffuser blade at a position along the width of the linear bar diffuser blade between the leading edge and a trailing edge of the linear bar diffuser blade, wherein the wave shape and the undulated contour comprise corresponding curvatures into and out of the width of the linear bar diffuser blade.
A linear bar diffuser, comprising:
- a grille frame, wherein the grille frame comprises an inlet configured to receive an air flow from a duct and an outlet configured to output the air flow to a conditioned space, wherein the inlet and the outlet are disposed on opposing sides of the grille frame;
- and
- a plurality of blades disposed in a blade section defined by the grille frame, wherein each blade of the plurality of blades includes a leading edge extending along a length of the blade, a width extending from the leading edge to a trailing edge of the blade, an undulated contour of the leading edge formed by peaks and valleys extending along the length and into and out of the width, and a wave shape extending along the length of the blade at a position along the width of the blade between the leading edge and the trailing edge, wherein the wave shape and the undulated contour comprise corresponding curvatures into and out of the width of the blade.
