Abstract

Described herein are embodiments of a furnace inlet water collector for an HVAC system. The inlet water collector may include a base having an air intake aperture; an inner wall having a first top end and a first bottom end, the first bottom end provided proximate to the base; an outer wall having a second top end and a second bottom end, the second bottom end provided proximate to the base, the inner wall having a diameter smaller than a diameter of the outer wall; one or more pipe stops provided proximate to the base and between the inner wall and outer wall, a height of the one or more pipe stops extending less than a height of the outer wall; and a drain coupled to the outer wall and in fluid communication with a channel displaced between the inner wall and the outer wall.

First claim

What is claimed is:

1. A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
a furnace comprising a cabinet including a combustion air inlet;
an inlet water collector mounted to the cabinet and coupled to the combustion air inlet; and
a combustion air intake pipe engaged with the inlet water collector, such that the combustion air intake pipe is in fluid communication with the combustion air inlet through the inlet water collector; and
wherein the inlet water collector comprises:
a longitudinal axis;
a base having an aperture;
an inner wall having a first top end and a first bottom end axially spaced from the first top end, wherein the first bottom end terminates proximate to the base;
an outer wall disposed about the inner wall, wherein the outer wall has a second top end and a second bottom end axially spaced from the second top end, wherein the second bottom end terminates proximate to the base, and wherein the inner wall has an outer diameter smaller than an inner diameter of the outer wall so that a channel is defined radially between the inner wall and the outer wall;
wherein the base extends radially outward from the longitudinal axis beyond the outer wall, and includes a plurality of holes configured to receive fasteners therethrough, and wherein the base is engaged with the cabinet;
one or more pipe stops provided proximate to the base, within the channel, wherein an axial length of the one or more pipe stops is less than an axial length of the outer wall; and
a drain coupled to the outer wall and in fluid communication with the channel.

2. The HVAC system of claim 1 , wherein the aperture is centered above the combustion air inlet.

3. The HVAC system of claim 1 , wherein an axial distance of the one or more pipe stops from the base, is greater than or equal to an axial distance of the drain from the base.

4. The HVAC system of claim 1 , wherein the combustion air intake pipe is set on the one or more pipe stops.

5. The HVAC system of claim 4 , wherein the inner diameter of the outer wall is equal to an outer diameter of the combustion air intake pipe.

6. The HVAC system of claim 5 , wherein the outer diameter of the inner wall is less than an inner diameter of the combustion air intake pipe.

7. The HVAC system of claim 1 further comprising a pipe clamp set on an outer face of the outer wall.

8. The HVAC system of claim 1 further comprising a drain clamp set on an outer face of the drain.

9. The HVAC system of claim 1 further comprising a screen set across the air intake aperture.

10. The HVAC system of claim 1 , wherein the inner wall is conical in shape.

11. The HVAC system of claim 1 , wherein at least one of the one or more pipe stops is mounted to the outer wall.

12. The HVAC system of claim 11 , wherein all of the one of the one or more pipe stops is mounted to the outer wall.

13. The HVAC system of claim 11 , wherein the at least one pipe stop mounted to the outer wall is mounted a distance from the base, such that the at least one pipe stop does not touch the base.

14. The HVAC system of claim 13 , wherein the channel at the base extends under the at least one pipe stop mounted to the outer wall.

15. The HVAC system of claim 12 , wherein all of the pipe stops mounted to the outer wall are mounted at a distance from the base, such that all of the pipe stops do not touch the base.

16. The HVAC system of claim 15 , wherein the channel at the base extends under all of the pipe stops mounted to the outer wall.

17. The HVAC system of claim 6 , wherein an inner surface of the intake pipe is mounted a distance away from the outer surface of the inner wall, such that a circumferential space exists between the intake pipe and inner wall.
