Abstract

An air diffuser configured to be positioned in a raised floor, in which the air diffuser includes a sleeve having a first end and a second end with an air flow passage extending through the sleeve from the first end to the second end, a diffuser face disposed at the first end of the sleeve and configured to be exposed to an environment in an installed position within the raised floor, a damper disposed at the second end of the sleeve, and a plenum chamber defined within the sleeve between the damper and the diffuser face.

First claim

The invention claimed is:

1. An air diffuser configured to be positioned in a floor, the air diffuser comprising:
a sleeve having a first end and a second end with an air flow passage extending through the sleeve from the first end to the second end;
a diffuser face disposed at the first end of the sleeve and configured to be exposed to an environment in an installed position within the floor;
a damper disposed at and in contact with an edge of the second end of the sleeve; and
a plenum chamber defined within the sleeve between the damper and the diffuser face, wherein the air flow passage extends through the plenum chamber.

2. The air diffuser of claim 1 , wherein the sleeve has an outer surface, and the air diffuser includes a drip tray coupled to the sleeve via connectors coupled to the outer surface at the second end.

3. The air diffuser of claim 2 , wherein the air flow passage is configured to direct an air flow through the air diffuser, and wherein the sleeve, the connectors, and the drip tray cooperatively define a plurality of inlet passages configured to receive the air flow into the air diffuser.

4. The air diffuser of claim 2 , comprising an actuator coupled to a side of the drip tray opposite the sleeve, wherein the actuator is coupled to the damper via a damper connector extending through the drip tray, and wherein the actuator is configured to adjust a position of the damper.

5. The air diffuser of claim 4 , wherein the actuator is configured to rotate the damper connector to adjust the position of the damper.

6. The air diffuser of claim 4 , comprising a controller communicatively coupled to the actuator, wherein the controller is configured to instruct the actuator to adjust the position of the damper.

7. The air diffuser of claim 2 , wherein the drip tray includes a pan and a wall surrounding and extending away from the pan, the wall includes a plurality of protrusions, and each connector is configured to couple to a respective protrusion of the plurality of protrusions.

8. The air diffuser of claim 1 , wherein the sleeve includes a shoulder formed in an inner surface of the sleeve, and the diffuser face abuts the shoulder.

9. The air diffuser of claim 1 , wherein the first end of the sleeve includes a first axial surface, the diffuser face includes a second axial surface, and the first and second axial surfaces are substantially flush in the installed position.

10. The diffuser of claim 1 , wherein the damper and the diffuser face are offset from one another to define a volume of the plenum chamber configured to enable pressurization and distribution of an air flow within the plenum chamber.

11. An air diffuser configured to be positioned in a floor, the air diffuser comprising:
a sleeve having a first end and a second end;
a diffuser face disposed at the first end of the sleeve and configured to be exposed to a conditioned space in an installed position within the floor;
a damper disposed at the second end of the sleeve and including a plurality of damper sections configured to adjustably block an opening of the second end to regulate a rate of air flow into the sleeve, wherein each damper section of the plurality of damper sections is rotatable relative to one another, and the damper abuts an edge of the second end of the sleeve; and
a plenum chamber defined within the sleeve between the damper and the diffuser face.

12. The air diffuser of claim 11 , wherein each damper section of the plurality of damper sections has a bow-tie shape.

13. The air diffuser of claim 11 , wherein the plurality of damper sections is configured to overlap with one another in an open position of the damper.

14. The air diffuser of claim 11 , comprising a damper connector extending between the diffuser face and a damper section of the plurality of damper sections, wherein the damper connector is rotationally fixed relative to the diffuser face and the damper section.

15. The air diffuser of claim 11 , comprising a drip pan configured to be positioned beneath the sleeve in the installed position.

16. The air diffuser of claim 15 , comprising a plurality of connectors coupled to the drip pan and to the second end of the sleeve to offset the drip pan from the sleeve and form a plurality of inlet passages of the air diffuser.

17. The air diffuser of claim 15 , comprising an actuator coupled to a side of the drip pan opposite the sleeve, and comprising a damper connector extending through the drip pan and between the damper and the actuator, wherein the actuator is configured to rotate the damper connector to adjust respective positions of the plurality of damper sections relative to one another to adjustably block the opening of the second end of the sleeve.

18. An air diffuser configured to be positioned in a floor, the air diffuser comprising:
a sleeve having a first end and a second end with an air flow passage extending through the sleeve from the first end to the second end;
a diffuser face coupled to the sleeve at the first end;
a damper in abutment with an edge of the sleeve at the second end to define a plenum chamber within the sleeve between the damper and the diffuser face, wherein the air flow passage extends through the plenum chamber; and
a damper connector extending through the plenum chamber and coupled to the damper and to the diffuser face, wherein the damper connector is configured to enable adjustment of a position of the damper via rotation of the diffuser face.

19. The air diffuser of claim 18 , wherein the diffuser face is configured to be exposed to a conditioned space in an installed position of the air diffuser within the floor, and the diffuser face is removable from the sleeve and the damper connector in the installed position.

20. The air diffuser of claim 19 , wherein the diffuser face includes a recess, an end of the damper connector is configured to extend into the recess, and the end and the recess have matching geometries.

21. The air diffuser of claim 20 , wherein the end is a first end, the damper includes a damper fastener, and a second end of the damper connector is configured to engage with the damper fastener.

22. The air diffuser of claim 18 , wherein the damper includes a plurality of damper sections that are rotatably adjustable relative to one another to adjust the position of the damper.

23. The air diffuser of claim 18 , wherein the sleeve includes a shoulder formed in an inner surface of the sleeve, wherein the diffuser face abuts the shoulder in an installed configuration, and wherein the diffuser face is configured to slidably rotate along the shoulder to adjust the position of the damper.

24. The air diffuser of claim 18 , wherein the damper includes tabs configured to impart a compressive force onto an outer surface of the second end of the sleeve to couple the damper to the edge of the sleeve at the second end.
