Abstract

A condensate drain pan including an inner front wall, an inner back wall and opposed inner side walls defining an inner perimeter, at least two outer front walls, an outer back wall and opposed outer side walls defining an outer perimeter. The condensate drain pan further includes at least one drain pan panel extending between the inner perimeter and the outer perimeter, and at least one drain opening disposed in the outer front wall.

Claims (53)

1. A condensate drain pan comprising:

an inner front wall, an inner back wall and opposing inner side walls defining an inner perimeter;

at least two outer front walls, an outer back wall and opposing outer side walls defining an outer perimeter of the condensate drain pan;

at least one drain pan panel, including a panel interior side and a panel exterior side, extending between the inner perimeter and the outer perimeter to form at least one condensate channel; and

at least one drain opening disposed in the at least two outer front walls.

2. The condensate drain pan of claim 1 , wherein each of the opposing outer side walls comprises a channel portion and a wall portion extending from the channel portion.

3. The condensate drain pan of claim 2 , wherein the at least one drain panel extends from the channel portion to form a lip therebetween.

4. The condensate drain pan of claim 3 , wherein at least one tab extends from the lip to the exterior side of the at least one drain panel.

5. The condensate drain pan of claim 1 , wherein the at least one condensate channel includes a front condensate channel including a front drain pan panel extending between the inner front wall and the at least two outer front walls.

6. The condensate drain pan of claim 5 , wherein the at least one drain opening comprises at least one drain aperture substantially aligned with the front condensate channel.

7. The condensate drain pan of claim 1 , wherein the at least one condensate channel includes a back condensate channel including a back drain pan panel extending between the inner back wall and the outer back wall.

8. The condensate drain pan of claim 1 , wherein the at least one condensate channel includes a first side condensate channel including a first side drain pan panel extending between one of the opposing inner side walls and one of the opposing outer side walls.

9. The condensate drain pan of claim 8 , wherein the at least one condensate channel includes a second side condensate channel including a second side drain pan panel extending between the other opposing inner side wall and the other opposing outer side wall.

10. The condensate drain pan of claim 8 , wherein the at least one drain opening comprises at least one drain aperture substantially aligned with the first side condensate channel.

11. The condensate drain pan of claim 9 , wherein the at least one drain opening comprises at least one drain aperture substantially aligned with the second side condensate channel.

12. A fan coil assembly comprising:

a casing;

a coil disposed within the casing, wherein the coil comprises at least one coil slab, and at least one coil conduit disposed in and protruding from the at least one coil slab;

a condensate drain pan positioned to receive at least a portion of condensate from the coil, wherein the condensate drain pan comprises

an inner front wall, an inner back wall and opposing inner side walls defining an inner perimeter;

at least two outer front walls, an outer back wall and opposing outer side walls defining an outer perimeter of the condensate drain pan;

at least one drain pan panel, including a panel interior side and a panel exterior side, extending between the inner perimeter and the outer perimeter to form at least one condensate channel; and

at least one drain opening disposed in the at least two outer front walls.

13. The fan coil assembly of claim 12 , further comprising a fan disposed in the casing.

14. The fan coil assembly of claim 12 , further comprising an auxiliary heating assembly operably coupled to the casing.

15. The fan coil assembly of claim 12 , wherein each of the opposing outer side walls comprises a channel portion and a wall portion extending from the channel portion.

16. The fan coil assembly of claim 15 , wherein the at least one drain panel extends from the channel portion to form a lip therebetween.

17. The fan coil assembly of claim 12 , wherein the at least one condensate channel includes a front condensate channel including a front drain pan panel extending between the inner front wall and the at least two outer front walls.

18. The fan coil assembly of claim 17 , wherein the at least one drain opening comprises at least one drain aperture substantially aligned with the front condensate channel.

19. The fan coil assembly of claim 12 , wherein the at least one condensate channel includes a back condensate channel including a back drain pan panel extending between the inner back wall and the outer back wall.

20. The fan coil assembly of claim 12 , wherein the at least one condensate channel includes a first side condensate channel including a first side drain pan panel extending between one of the opposing inner side walls and one of the opposing outer side wall.

21. The fan coil assembly of claim 20 , wherein the at least one condensate channel includes a second side condensate channel including a second side drain pan panel extending between the other opposing inner side wall and the other opposing outer side wall.

22. The fan coil assembly of claim 20 , wherein the at least one drain opening comprises at least one drain aperture substantially aligned with the first side condensate channel.

23. The fan coil assembly of claim 21 , wherein the at least one drain opening comprises at least one drain aperture substantially aligned with the second side condensate channel.

24. The fan coil assembly of claim 16 , wherein at least one tab extends from the lip to the exterior side of the at least one drain panel.

25. An HVAC system comprising:

a fan coil assembly operably coupled to a heat pump, wherein the fan coil assembly comprises:

a coil and a fan disposed in a casing;

a condensate drain pan positioned to receive at least a portion of condensate from the coil, wherein the condensate drain pan comprises:

an inner front wall, an inner back wall and opposing inner side walls defining an inner perimeter;

at least two outer front walls, an outer back wall and opposing outer side walls defining an outer perimeter of the condensate drain pan;

at least one drain pan panel, including a panel interior side and a panel exterior side, extending between the inner perimeter and the outer perimeter to form at least one condensate channel; and

at least one drain opening disposed in the at least two outer front walls.

26. The HVAC system of claim 25 , wherein each of the opposing outer side walls comprises a channel portion and a wall portion extending from the channel portion.

27. The HVAC system of claim 26 , wherein the at least one drain panel extends from the channel portion to form a lip therebetween.

28. The HVAC system of claim 25 , wherein the at least one condensate channel includes a front condensate channel including a front drain pan panel extending between the inner front wall and the at least two outer front walls.
