Abstract

A condensate drain pan including a drain pan surface, a front wall, including a front wall longitudinal axis, a rear wall, and opposing side walls. The front wall, the rear wall, and the opposing side walls extend from the drain pan surface. The front wall includes a first aperture and a second aperture. The first aperture and the second aperture include an aperture axis.

First claim

What is claimed is:

1. A fan coil assembly comprising: a
casing;
a coil disposed within the casing, wherein the coil comprises a first coil slab and a second coil slab, and wherein the first coil slab and the second coil slab are configured to form an apex;
a mounting bracket;
a condensate drain pan positioned to receive at least a portion of condensate that may drip from the coil, wherein the condensate drain pan comprises:
a drain pan surface having a straight section spaced from the apex of the coil;
a front wall, including a front wall longitudinal axis;
a panel exterior side;
a channel member longitudinally formed on the panel exterior side, wherein the channel member is substantially centered on a longitudinal axis of the panel exterior side, wherein the channel member is engaged to the mounting bracket;
a rear wall; and
opposing side walls having a curvature adjacent to the straight section of the drain pan surface;
wherein the front wall, the rear wall, and the opposing side walls extend from the drain pan surface;
wherein the front wall includes a first aperture and a second aperture substantially centered in the front wall;
wherein the first aperture and the second aperture include an aperture axis; and
wherein the aperture axis forms an angle less than 90 degrees with the front wall longitudinal axis;
wherein a first space is created between an edge of the first coil slab and a top edge of one of the opposing side walls, and a second space is created between an edge of the second coil slab and a top edge of the other of the opposing side walls; and
wherein the first space and the second space comprise a first dimension equal to 0.375 inch.

2. The fan coil assembly of claim 1 , further comprising a fan disposed in the casing.

3. The fan coil assembly of claim 2 , further comprising an auxiliary heating assembly affixed to the casing.

4. The fan coil assembly of claim 1 , wherein a third space is created between an end of the first coil slab and the top edge of the one of the opposing side walls, and a fourth space is created between an end of the second coil slab and the top edge of the other of the opposing side walls.

5. The fan coil assembly of claim 4 , wherein the third space and the fourth space comprise a second dimension equal to 0.750 inch.

6. An HVAC system comprising:
a fan coil assembly operably coupled to a heat pump, wherein the fan coil assembly comprises:
a coil, wherein the coil comprises a first coil slab and a second coil slab, and wherein the first coil slab and the second coil slab are configured to form an apex, and a fan disposed in a casing;
a mounting bracket;
a condensate drain pan positioned to receive at least a portion of condensate from the coil, wherein the condensate drain pan comprises:
a drain pan surface having a straight section spaced from the apex of the coil; a front wall, including a front wall longitudinal axis;
a panel exterior side;
a channel member longitudinally formed on the panel exterior side, wherein the channel member is substantially centered on a longitudinal axis of the panel exterior side, wherein the channel member is engaged to the mounting bracket;
a rear wall; and
opposing side walls having a curvature adjacent to the straight section of the drain pan surface;
wherein the front wall, the rear wall, and the opposing side walls extend from the drain pan surface;
wherein the front wall includes a first aperture and a second aperture substantially centered in the front wall;
wherein the first aperture and the second aperture include an aperture axis; and wherein the aperture axis forms an angle less than 90 degrees with the front wall longitudinal axis;
wherein a first space is created between an edge of the first coil slab and a top edge of one of the opposing side walls, and a second space is created between an edge of the second coil slab and a top edge of the other of the opposing side walls; and
wherein the first space and the second space comprise a first dimension equal to 0.375 inch.

7. The HVAC system of claim 6 , wherein a third space is created between an end of the first coil slab and the top edge of the one of the opposing side walls, and a fourth space is created between an end of the second coil slab and the top edge of the other of the opposing side walls.

8. The HVAC system of claim 7 , wherein the third space and the fourth space comprise a second dimension equal to 0.750 inch.
