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 device of a chilled beam comprising:
a duct interface configured to couple the device to an air duct;
a fin structure comprising a left fin and a right fin, wherein the right fin is disposed opposite the left fin along a length of the device, and wherein each of the left fin and the right fin comprises an arcuate shape;
a left vent disposed in the left fin for directing air from the air duct, through the fin structure, and out of the left fin such that the arcuate shape of the left fin guides the air to the left instead of downward, relative to the chilled beam, via the Coanda effect, as the air exits the left fin;
a right vent disposed in the right fin for directing air from the air duct, through the fin structure, and out of the right fin such that the arcuate shape of the right fin guides the air to the right instead of downward, relative to the chilled beam, via the Coanda effect, as the air exits the right fin;
one or more cooling coils disposed in the left vent, the right vent, or both; and
one or more light sources disposed in the left fin, the right fin, or both.

2. The device of claim 1 , comprising a heat source disposed adjacent to the one or more cooling coils.

3. The device of claim 2 , comprising:
a first piping manifold coupled to the one or more cooling coils;
and a second piping manifold coupled to the heat source.

4. The device of claim 2 , comprising a humidity controller coupled to the heat source and configured to activate the heat source in response to a humidity measurement.

5. The device of claim 2 , comprising a temperature controller coupled to the heat source and configured to activate the heat source in response to a temperature measurement.

6. The device of claim 1 , comprising a piping manifold coupled to the one or more cooling coils.

7. The device of claim 1 , comprising a plurality of pipes disposed underneath the one or more cooling coils.

8. The device of claim 1 , wherein the one or more light sources comprise:
a direct light source;
an indirect light source; and
a controller configured to turn on the direct light source, the indirect light source, or both.

9. The device of claim 1 , wherein the one or more light sources comprise:
a direct light source disposed in a bottom portion of the fin structure; and
an indirect light source disposed in a top portion of the fin structure.

10. The device of claim 1 , comprising a temperature controller coupled to the one or more cooling coils and configured to provide chilled water to the one or more cooling coils in response to a temperature measurement.

11. The device of claim 1 , comprising an air duct disposed over the fin structure and coupled to the duct interface.

12. A device of a chilled beam comprising:
a duct interface configured to couple the device to an air duct;
a fin structure having an arcuate shape;
a vent disposed in the fin structure for directing a jet flow of air from the air duct, through the fin structure, and out of the fin structure such that the arcuate shape of the fin structure guides the jet flow sideways instead of downward, relative to the chilled beam, via the Coanda effect, as the air exits the fin structure, wherein the arcuate shape of the fin structure curves upwardly away from the vent, and the jet flow is guided along the arcuate shape after the jet flow exits the fin structure; and
a cooling coil disposed in the vent.

13. The device of claim 12 , comprising a light source disposed in the fin structure.

14. The device of claim 13 , wherein the light source comprises:
a direct light source; and
an indirect light source, wherein the indirect light source and the direct light source are disposed above the vent.

15. The device of claim 13 , wherein the light source disposed in the fin structure comprises:
a direct light source disposed in a bottom portion of the fin structure; and
an indirect light source disposed in a top portion of the fin structure, wherein the indirect light source and the direct light source are disposed above the vent.

16. A device of a chilled beam comprising:
a duct interface configured to couple the device to an air duct;
a fin structure having an arcuate shape and a vent, wherein the vent is configured to direct airflow from the air duct, through the fin structure, and out of the fin structure such that the arcuate shape of the fin structure pulls the airflow exiting the fin structure toward the chilled beam, via the Coanda effect, and wherein the fin structure is disposed generally above the vent; and
a cooling coil disposed in the vent.

17. The device of claim 16 , comprising:
a heat source disposed adjacent to the cooling coil; and
a humidity controller coupled to the heat source and configured to activate the heat source in response to a humidity measurement.

18. The device of claim 16 , comprising a piping manifold coupled to the cooling coil.

19. The device of claim 16 , comprising:
a first piping manifold coupled to the cooling coil;
a heat source coil disposed adjacent to the cooling coil; and
a second piping manifold coupled to the heat source coil.

20. The device of claim 16 , comprising a light source disposed in the fin structure.
