Abstract

An air handling unit has an interior wall configured to selectively retain a removable component of the air handling unit. An air handling unit has an interior wall configured as a drain pan. An air handling unit has an outer skin joined to the interior wall, an insulator disposed between the interior wall and the outer skin, and the interior wall has a mounting channel configured to selectively retain a removable component of the air handling unit.

First claim

What is claimed is:

1. An air handling unit, comprising:
a first interior wall comprising:
a first integral rail and a second integral rail, wherein each of the first integral rail and the second integral rail protrude from the first interior wall towards an interior space of the air handling unit, wherein the first interior wall is fixed relative to the air handling unit, and wherein the first integral rail and the second integral rail are fixed relative to the first interior wall; and
a first mounting channel that is open toward the interior space and that is configured to selectively slidably receive a removable component of the air handling unit; and

a second interior wall disposed opposite of the first interior wall and comprising:
a third integral rail and a fourth integral rail, wherein each of the third integral rail and the fourth integral rail protrude from the second interior wall towards the interior space of the air handling unit, wherein the second interior wall is fixed relative to the air handling unit, and wherein the third integral rail and the fourth integral rail are fixed relative to the second interior wall; and
a second mounting channel that is open toward the interior space and that is configured to selectively slidably receive the removable component of the air handling unit;

wherein the first integral rail, the second integral rail, and the first mounting channel of the first interior wall form at least a portion of the fluid duct through the air handling unit, wherein the first mounting channel is bound by the first integral rail on an upstream side and bound by the second integral rail on a downstream side with respect to a primary airflow direction through the air handling unit such that the first integral rail and the second integral rail retain the removable component within the first mounting channel by receiving a complementary shaped structure of the removable component within the first mounting channel and retaining the complementary shaped structure of the removable component within the first mounting channel with the first integral rail and the second integral rail; and
wherein the third integral rail, the fourth integral rail, and the second mounting channel form at least a portion of the fluid duct through the air handling unit, wherein the second mounting channel is bound by the third integral rail on an upstream side and bound by the fourth integral rail on a downstream side with respect to a primary airflow direction through the air handling unit such that the third integral rail and the fourth integral rail retain the removable component within the second mounting channel by receiving a second complementary shaped structure of the removable component within the second mounting channel and retaining the second complementary shaped structure of the removable component within the second mounting channel with the third integral rail and the fourth integral rail.

2. The air handling unit of claim 1 , wherein the first mounting channel and the second mounting channel are configured to slidably receive the removable component.

3. The air handling unit of claim 2 , wherein (1) at least one of the first integral rail and the second integral rail and (2) at least one of the third integral rail and the fourth integral rail restricts movement of the removable component.

4. The air handling unit of claim 1 , wherein the removable component is a blower assembly.

5. The air handling unit of claim 1 , wherein the removable component is a refrigeration coil assembly.

6. The air handling unit of claim 1 , wherein the removable component is a heater assembly.

7. An air handling unit, comprising:
an interior wall;
an outer skin joined to the interior wall; and
an insulator disposed between the interior wall and the outer skin;
wherein the interior wall comprises (1) a first integral rail and a second integral rail that each protrude from the interior wall towards an interior space of the air handling unit and (2) a mounting channel that is open toward the interior space and that is configured to selectively slidably receive a removable component of the air handling unit;
wherein the interior wall is fixed relative to the outer skin, wherein the first integral rail and the second integral rail are fixed relative to the interior wall, wherein the first integral rail, the second integral rail, and the mounting channel form at least a portion of the fluid duct through the air handling unit, wherein the first integral rail is located immediately adjacently upstream of the mounting channel and the second integral rail is located immediately adjacently downstream of the mounting channel with respect to a primary airflow direction through the fluid duct such that the integral rail retains the removable component within the mounting channel by receiving a complementary shaped structure of the removable component within the mounting channel and retaining the complementary shaped structure of the removable component within the mounting channel with the first integral rail and the second integral rail, and wherein the insulator is further disposed between the outer skin and at least one of the first integral rail, the second integral rail, and the mounting channel.

8. The air handling unit according to claim 7 , wherein the interior wall is further configured as a drain pan.

9. The air handling unit according to claim 7 , wherein the interior wall further comprises electrical conduit apertures extending toward the outer skin.

10. The air handling unit according to claim 7 , wherein the removable component is an air filter.

11. The air handling unit according to claim 7 , wherein the air handling unit comprises a plurality of interior walls configured to selectively retain a refrigeration coil assembly, a heater assembly, and a blower assembly.
