Air diffuser

An air diffuser configured to receive an air flow from ductwork, comprising:

• a mounting plate comprising a center portion, a first opening formed in the center portion, and a wall coupled to the center portion and extending away from the center portion;
• a flow adapter attached to the mounting plate across the first opening and forming a chamber between the flow adapter and the mounting plate, wherein the flow adapter comprises a base plate and a face extending from the base plate;
• a plurality of converging openings formed through the face and extending away from the face, wherein each converging opening of the plurality of converging openings is disposed at an oblique angle relative to an axis extending parallel to the center portion;
• and
• a diffusion plate coupled to the mounting plate to form a second opening between one or more of first edges of the wall and second edges of the diffusion plate, wherein the second opening extends about at least a portion of a perimeter of the diffusion plate, and the air diffuser is configured to discharge the air flow via the second opening.

A heating, ventilating, air conditioning, and refrigeration (HVAC&R) system, comprising:

• ductwork configured to direct an air flow toward an interior space serviced by the HVAC&R system;
• an air diffuser configured to receive the air flow from the ductwork and discharge the air flow into the interior space, comprising:
• a mounting plate comprising a center portion and a wall extending from the center portion, wherein the center portion defines an opening fluidly coupled to the ductwork and configured to receive the air flow from the ductwork;
• a diffusion plate coupled to the mounting plate to form an outlet of the air diffuser extending between the wall and the diffusion plate;
• and
• a flow adapter coupled to the mounting plate and covering the opening, wherein the flow adapter comprises:
• a base plate extending parallel to the center portion;
• a face extending from the base plate, wherein the base plate and the face at least partially define a chamber configured to receive the air flow from the opening;
• and
• a plurality of tubular nozzles formed in and extending away from the face, wherein the plurality of tubular nozzles is configured to direct the air flow from the chamber and toward the outlet between the wall and the diffusion plate with limited obstruction of the air flow caused by the mounting plate and the diffusion plate.
