Abstract

A panel provided for use in an air handling unit includes a skin and a fixture, the fixture and the skin composed of a metal material. The fixture has a base, with an opening formed in the base. The base includes at least one riser extending substantially perpendicular to the base, the at least one riser being secured to the skin to form an enclosed chamber between the skin and the fixture. A perforated sheet is disposed over the opening, a layer of film disposed on a surface of the perforated sheet facing the skin. A first insulating material is disposed on a surface of the film layer opposite the perforated sheet. A second insulating material is disposed in the enclosed chamber between the first insulating material and the skin.

Claims

1. A panel for use in an air handling unit comprising:

a skin;

a fixture, the fixture having;

a base disposed opposite the skin;

an opening formed in the base; and

at least one riser extending substantially perpendicular from the base, the at least one riser being secured to the skin to form an enclosed chamber between the skin and the fixture; and

a perforated sheet disposed over the opening;

a layer of film disposed on a surface of the perforated sheet facing the skin;

a first insulating material disposed on a surface of the film layer opposite the perforated sheet; and

a second insulating material disposed in the enclosed chamber between the first insulating material and the skin.

2. The panel of claim 1 wherein the perforated sheet is disposed inside the fixture.

3. The panel of claim 1 wherein the perforated sheet is disposed exterior of the fixture.

4. The panel of claim 1 wherein the first insulating material occupies from about one-third to about two-thirds of the chamber.

5. The panel of claim 1 wherein the first insulating material occupies about one-half of the chamber.

6. The panel of claim 1 wherein the second insulating material is a foam.

7. The panel of claim 6 wherein the foam is a polyurethane foam.

8. The panel of claim 7 wherein the polyurethane foam is injected into the panel.

9. The panel of claim 8 wherein the injected polyurethane foam compresses the first insulating material up to about 10 percent.

10. The panel of claim 9 wherein the injected polyurethane foam bonds to surfaces of the skin and fixture.

11. An air handling unit framework comprising:

a skin;

a fixture, the fixture having;

a base disposed opposite the skin;

an opening formed in the base; and

at least one riser extending substantially perpendicular from the base, the at least one riser being secured to the skin to form an enclosed chamber between the skin and the fixture; and

a perforated sheet disposed over the opening;

a layer of film disposed on a surface of the perforated sheet facing the skin;

a first insulating material disposed on a surface of the film layer opposite the perforated sheet;

a second insulating material disposed in the enclosed chamber between the first insulating material and the skin;

a plurality of interconnected structural members forming a plurality of interconnected frames, each frame of the plurality of frames receiving a panel; and

wherein the plurality of interconnected frames and corresponding panels are configured and disposed to form an air handling unit framework.

12. The panel of claim 11 wherein the perforated sheet is disposed inside the fixture.

14. The panel of claim 11 wherein the first insulating material occupies from about one-third to about two-thirds of the chamber.

15. The panel of claim 11 wherein the second insulating material is a foam.

13. The panel of claim 111 wherein the perforated sheet is disposed exterior of the fixture.

16. A method of assembling a panel for use in an air handling unit, comprising the steps of:

providing a skin;

providing a fixture, the fixture having;

a base disposed opposite the skin;

an opening formed in the base; and

at least one riser extending from the base; and

bending the at least one riser substantially perpendicular from the base;

disposing a perforated sheet over the opening;

disposing a layer of film on a surface of the perforated sheet facing the skin;

disposing a first insulating material on a surface of the film layer opposite the perforated sheet;

securing the at least one riser to the skin to form an enclosed chamber between the skin and the fixture; and

disposing a second insulating material in the enclosed chamber between the first insulating material and the skin.

17. The method of claim 17 wherein the step of disposing a perforated sheet over the opening includes the step of disposing a perforated sheet inside the fixture over the opening.

18. The method of claim 17 wherein the step of disposing a perforated sheet over the opening includes the step of disposing a perforated sheet exterior of the fixture over the opening.

19. The method of claim 17 wherein the step of disposing a second insulating material in the enclosed chamber is achieved by injection.

20. The method of claim 17 wherein the first insulating material occupies from about one-third to about two-thirds of the chamber.
