Abstract

A device comprising a fin structure, a vent disposed in the fin structure, a cooling coil disposed in the vent, a light disposed in the fin structure and wherein the fin structure is configured to create a Coanda effect for air exiting the vent.

First claim

What is claimed is:

1. A chilled beam, comprising:
a fin structure comprising an arcuate shape, wherein the fin structure is configured to receive air from an air duct; and
a vent disposed in the fin structure, wherein the vent is configured to direct the air out of the fin structure, and wherein the arcuate shape of the fin structure is configured to guide the air discharged from the vent to flow laterally outward relative to the chilled beam.

2. The chilled beam of claim 1 , wherein the fin structure comprises a first fin and a second fin, wherein the first fin and the second fin extend along a length of the chilled beam, and wherein the first fin and the second fin each comprise the arcuate shape.

3. The chilled beam of claim 2 , wherein the first fin and the second fin are symmetrical about the length of the chilled beam.

4. The chilled beam of claim 2 , wherein the vent is a first vent disposed in the first fin, and the chilled beam comprises a second vent disposed in the second fin.

5. The chilled beam of claim 2 , comprising:
a first support coupled to the first fin; and
a second support coupled to the second fin, wherein the first support and the second support are configured to be attached to a support structure and suspend the chilled beam from the support structure.

6. The chilled beam of claim 1 , comprising one or more heat exchanger coils disposed therein, wherein the one or more heat exchanger coils are disposed downstream of the air duct and upstream of the vent relative to a flow direction of the air through the chilled beam, and wherein the one or more heat exchanger coils are configured to circulate a fluid therethrough and remove heat from the air received via the air duct.

7. The chilled beam of claim 6 , comprising a heat source disposed adjacent to the one or more heat exchanger coils, wherein the heat source is configured to reduce condensation formation on the one or more heat exchanger coils.

8. The chilled beam of claim 7 , wherein the heat source comprises one or more pipes configured to circulate a heated fluid therethrough.

9. The chilled beam of claim 1 , comprising:
one or more direct light sources disposed at a bottom portion of the fin structure; and
one or more indirect light sources disposed at a top portion of the fin structure.

10. A chilled beam, comprising:
a duct interface configured to couple to an air duct and direct air from the air duct into the chilled beam;
a fin structure comprising an arcuate shape; and
a vent disposed in the fin structure, wherein the vent is configured to receive air from the air duct and direct the air out of the chilled beam, and wherein the arcuate shape of the fin structure is configured to guide the air discharged from the vent laterally outward, instead of downward, relative to the chilled beam.

11. The chilled beam of claim 10 , wherein the fin structure comprises a first fin and a second fin, the first fin and the second fin extend along a length of the chilled beam, the first fin and the second fin each comprise the arcuate shape, the first fin extends in a first lateral direction relative to the air duct, and the second fin extends in a second lateral direction, opposite the first lateral direction, relative to the air duct.

12. The chilled beam of claim 11 , wherein the vent is a first vent disposed in the first fin, and the chilled beam comprises a second vent disposed in the second fin.

13. The chilled beam of claim 10 , comprising one or more heat exchanger coils disposed therein and configured to remove heat from the air received via the air duct.

14. The chilled beam of claim 13 , comprising a heat source disposed adjacent to the one or more heat exchanger coils, wherein the heat source is configured to reduce formation of condensation on the one or more heat exchanger coils.

15. The chilled beam of claim 14 , wherein the heat source is disposed on a side of the one or more heat exchanger coils opposite the air duct.

16. A chilled beam, comprising:
a duct interface configured to receive an air flow and direct the air flow into the chilled beam;
a fin structure comprising an arcuate shape; and
a vent disposed in the fin structure, wherein the vent is configured to discharge the air flow from the chilled beam, wherein the arcuate shape of the fin structure curves upwardly, relative to a vertical direction, and away from the vent, and wherein the fin structure is configured to guide the air flow discharged via the vent along the arcuate shape of the fin structure in a lateral direction.

17. The chilled beam of claim 16 , wherein the fin structure comprises a plurality of fins, each fin of the plurality of fins extends along a length of the chilled beam, and each fin of the plurality of fins comprises the arcuate shape.

18. The chilled beam of claim 17 , wherein the plurality of fins comprises a first fin and a second fin, and the first fin and the second fin are symmetrical about the length of the chilled beam.

19. The chilled beam of claim 16 , comprising:
one or more heat exchanger coils disposed therein and configured to circulate a fluid therethrough;
at least one fluid inlet fluidly coupled to the one or more heat exchanger coils, wherein the at least one fluid inlet is configured to direct the fluid into the chilled beam and the one or more heat exchanger coils; and
at least one fluid outlet fluidly coupled to the one or more heat exchanger coils, wherein the at least one fluid outlet is configured to direct the fluid out of the one or more heat exchanger coils and the chilled beam.

20. The chilled beam of claim 19 , wherein:
the fluid comprises a chilled fluid, and the one or more heat exchanger coils are configured to remove heat from the air flow received via the duct interface;
the fluid comprises a heated fluid, and the one or more heat exchanger coils are configured to reduce formation of condensation on the one or more heat exchanger coils; or
both.
