Abstract

An intake hood system for a heating, ventilation, and/or air conditioning (HVAC) unit includes an intake hood having an inlet configured to receive an air flow into the intake hood, a first support configured to engage a first end of an air filter, and a second support configured to engage a second end of the air filter, where the first support is configured to align with a boundary of the inlet. The intake hood system also includes a lock bar configured to couple to the intake hood while abutting the first support and the second support to secure the air filter within the intake hood.

First claim

What is claimed is:

1. An intake hood system for a heating, ventilation, and/or air conditioning (HVAC) unit, comprising:
an intake hood including an inlet configured to receive an air flow into the intake hood and including a flange extending outwardly from the inlet;
a first support configured to engage a first end of an air filter and a second support configured to engage a second end of the air filter, wherein the first support is configured to align with a boundary of the inlet; and
a lock bar configured to removably couple to the flange while abutting the first support to secure the air filter, the first support, and the second support within the intake hood against a force of gravity, wherein the lock bar is fixed to the flange while coupled to the flange.

2. The intake hood system of claim 1 , wherein the intake hood includes a first side panel that defines a first boundary portion of the inlet and a second side panel that defines a second boundary portion of the inlet, wherein the first side panel comprises the flange.

3. The intake hood system of claim 1 , wherein the intake hood includes a first side panel that defines a first boundary portion of the inlet and a second side panel that defines a second boundary portion of the inlet, wherein the first side panel comprises the flange, and the intake hood system includes a second lock bar configured to couple to an additional flange of the second side panel to secure the air filter within the intake hood.

4. The intake hood system of claim 1 , comprising:
a third support configured to engage a first end of an additional air filter; and
an intermediate bracket including both the second support and a fourth support configured to engage a second end of the additional air filter.

5. The intake hood system of claim 4 , comprising:
a first side panel that defines a first boundary portion of the inlet;
a second side panel that defines a second boundary portion of the inlet;
a first lateral support of the first side panel configured to engage a first lateral side of the additional air filter; and
a second lateral support of the second side panel configured to engage a second lateral side of the additional air filter that is opposite the first lateral side.

6. The intake hood system of claim 5 , wherein the third support is configured to be disposed between the first lateral support of the first side panel and the second lateral support of the second side panel.

7. The intake hood system of claim 5 , wherein the first and second lateral supports comprise C-channels formed via respective additional flanges of the first side panel and the second side panel.

8. The intake hood system of claim 4 , comprising the air filter and the additional air filter, wherein the air filter includes a plurality of air filter segments, and the additional air filter includes a plurality of additional air filter segments.

9. The intake hood system of claim 1 , wherein the lock bar includes a rivet nut configured to threadingly engage with a bolt extending through the flange to couple the lock bar to the intake hood.

10. The intake hood system of claim 1 , wherein the lock bar is configured to couple to the intake hood along a length extending in a first direction transverse to a second direction in which the first support and the second support extend.

11. The intake hood system of claim 1 , wherein the lock bar comprises a flattened plate, an angular bracket, or a tube.

12. The intake hood system of claim 1 , wherein the first support comprises a first C-channel.

13. The intake hood system of claim 12 , wherein the second support comprises a second C-channel.

14. The intake hood system of claim 13 , wherein the second support comprises an I-bracket that includes the second C-channel and a third C-channel that are open toward opposite directions.

15. An intake hood system for a heating, ventilation, and/or air conditioning (HVAC) unit, comprising:
an intake hood defining an inlet configured to receive an air flow into the intake hood;
a first support configured to engage a first end of an air filter and a second support configured to engage a second end of the air filter, wherein the first support is configured to align with a first boundary portion of the inlet and is configured to be disposed within the intake hood;
a side panel of the intake hood defining a second boundary portion of the inlet, wherein the side panel comprises a flange extending outwardly from the inlet;
a lock bar configured to couple to the flange to secure the air filter within the intake hood; and
an additional lock bar configured to couple to an additional side panel of the intake hood to secure the air filter within the intake hood, wherein the lock bar and the additional lock bar are configured to separately couple to the intake hood, and wherein the lock bar and the additional lock bar are separately removable from the intake hood.

16. The intake hood system of claim 15 , wherein the flange extends along the side panel in a first direction transverse to a second direction in which the first support and the second support extend.

17. An intake hood system for a heating, ventilation, and/or air conditioning (HVAC) unit, comprising:
an intake hood comprising an inlet configured to receive an air flow into the intake hood;
a first support configured to engage a first end of an air filter and a second support configured to engage a second end of the air filter, wherein the first support is configured to align with a first boundary portion of the inlet, and wherein the first support and the second support are configured to be disposed within the intake hood;
a first side panel of the intake hood defining a second boundary portion of the inlet;
a second side panel of the intake hood defining a third boundary portion of the inlet;
a first lateral support of the first side panel configured to engage a first lateral side of an additional air filter;
a second lateral support of the second side panel configured to engage a second lateral side of the additional air filter that is opposite the first lateral side;
a first lock bar configured to couple to the first side panel; and
a second lock bar configured to couple to the second side panel, wherein the first lock bar and the second lock bar are configured to secure the air filter within the intake hood.
