Abstract

A fan coil unit is provided including a cabinet formed from a plurality of panels. A fan assembly is configured to circulate air through the cabinet. A heat exchanger assembly is positioned within the cabinet. The heat exchanger assembly includes at least one heat exchanger coil arranged in a heat transfer relationship with the air circulating through the cabinet. An inner surface of at least one of the plurality of panels is partially lined with an elastomeric foam insulation so that the air circulating through the cabinet does not contact the portion of the at least one panel lined with the elastomeric foam insulation.

First claim

The invention claimed is:

1. A drain pan assembly comprising:
a rigid body having a horizontal section adjacent a first end and an angled section extending from the horizontal section to a second, opposite end such that a plane of the second end is spaced apart from a plane of the first end by a vertical distance, wherein at least one side of the angled section is oriented to direct condensate toward a center of the angled section;
an elastomeric foam insulation forming a lining over a surface of the rigid body;
a first connector extending from the first end of the rigid body, the first connector including:
a channel; and
a transition portion arranged between the first end of the rigid body and the channel, the transition portion extending at an angle to the horizontal section of the rigid body; and
a drain pan including at least one drain, the drain pan having a contour complementary to the transition portion such that the drain pan is positioned adjacent the transition portion in overlapping arrangement with the horizontal section of the rigid body, wherein the drain pan is aligned with the elastomeric foam insulation positioned on the angled section of the rigid body to receive a flow therefrom.

2. The drain pan assembly according to claim 1 , wherein the at least one side of the angled section includes a first side and a second side arranged at an upward angle to a center of the angled section of the body.

3. The drain pan assembly according to claim 1 , wherein the channel is configured to align with a panel of a cabinet of a fan coil unit.

4. The drain pan assembly according to claim 1 , further comprising a second connector extending from the second end of the rigid body, the second connector including a channel configured to align with a panel of a cabinet of a fan coil unit.

5. The drain pan assembly according to claim 1 , wherein the transition portion is triangular in shape.

6. The drain pan assembly according to claim 1 , wherein the portion of the drain pan abuts the elastomeric foam insulation positioned over the angled section of the rigid body to form a flow path from the angled section to the drain pan.
