Abstract

An acoustic treatment for an indoor HVAC component is provided having an inner liner and at least one aperture formed through the inner liner. An acoustic absorber is positioned adjacent the inner liner. A gap, including a width dimension, is formed between the inner liner and the acoustic absorber.

First claim

What is claimed is:

1. An acoustic treatment for an indoor HVAC enclosure comprising:
an inner liner;
at least one aperture formed through the inner liner;
an acoustic absorber positioned adjacent the inner liner;
a gap, including a width dimension, formed between the inner liner and the acoustic absorber; and
a rail extending through the inner liner, the rail configured to mount an HVAC component.

2. The acoustic treatment of claim 1 , wherein the width dimension is less than or equal to approximately 15 millimeters.

3. The acoustic treatment of claim 1 , wherein the inner liner comprises a metal.

4. The acoustic treatment of claim 1 , wherein the acoustic absorber comprises at least one of foam and fiberglass.

5. The acoustic treatment of claim 1 , wherein the at least one aperture further comprises a plurality of apertures formed in a pattern.

6. The acoustic treatment of claim 1 , wherein the at least one aperture is shaped as at least one of a circle, a triangle, a square, a pentagon, or a hexagon.

7. An indoor HVAC assembly comprising:
an enclosure including at least one wall;
a fan assembly disposed within the enclosure; and
an acoustic treatment coupled to the at least one wall and positioned proximate to the fan assembly, wherein the acoustic treatment comprises:
an inner liner,
at least one aperture formed through the inner liner,
an acoustic absorber positioned adjacent the inner liner, and
a rail extending through the inner liner, the rail configured to mount an HVAC component, and

a gap, including a width dimension, formed between the inner liner and the acoustic absorber.

8. The indoor HVAC assembly of claim 7 , wherein the width dimension is less than or equal to approximately 15 millimeters.

9. The indoor HVAC assembly of claim 7 , wherein the inner liner comprises a metal.

10. The indoor HVAC assembly of claim 7 , wherein the acoustic absorber comprises at least one of foam and fiberglass.

11. The indoor HVAC assembly of claim 7 , wherein the at least one aperture further comprises a plurality of apertures formed in a pattern.

12. The indoor HVAC assembly of claim 7 , wherein the at least one aperture is shaped as at least one of a circle, a triangle, a square, a pentagon, or a hexagon.

13. An HVAC system comprising:
an enclosure including at least one wall;
a fan assembly disposed within the enclosure; and
an acoustic treatment coupled to the at least one wall and positioned proximate to the fan assembly, wherein the acoustic treatment comprises:
an inner liner,
at least one aperture formed through the inner liner,
an acoustic absorber positioned adjacent the inner liner, and
a rail extending through the inner liner, the rail configured to mount an HVAC component, and

a gap, including a width dimension, formed between the inner liner and the acoustic absorber.

14. The HVAC system of claim 13 , wherein the width dimension is less than or equal to approximately 15 millimeters.

15. The HVAC system of claim 13 , wherein the at least one aperture further comprises a plurality of apertures formed in a pattern, and the at least one aperture is shaped as at least one of a circle, a triangle, a square, a pentagon, or a hexagon.
