Abstract

The present application provides an evaporator. The evaporator may include a housing, a coil assembly mounted within the housing, and a fan housing positioned within the housing. The fan housing may include a fan and a replaceable venturi ring sized to accommodate the fan.

First claim

We claim:

1. An evaporator, comprising:
an evaporator housing, the evaporator housing comprising a top panel and a bottom drain pan;
a coil assembly mounted within the evaporator housing; and
a fan housing positioned within the evaporator housing, wherein the fan housing comprises a grill and four edges extending from the grill into the evaporator housing, wherein the fan housing and grill are together slidably removable from the evaporator housing;
wherein the fan housing comprises a replaceable fan and a replaceable venturi ring sized to accommodate the replaceable fan such that the fan housing can accommodate a plurality of differently sized replaceable fans and a plurality of differently sized replaceable venturi rings, wherein the replaceable fan is configured to direct airflow out of the fan housing through the grill;
wherein the fan housing comprises a fan aperture in a top panel of the fan housing and the replaceable venturi ring is positioned within the fan aperture.

2. The evaporator of claim 1 , wherein the fan housing comprises a fan assembly therein.

3. The evaporator of claim 2 , wherein the fan assembly comprises the replaceable fan, a fan motor, and a fan mounting bracket.

4. The evaporator of claim 1 , wherein the replaceable fan comprises a backward incline centrifugal fan.

5. The evaporator of claim 1 , wherein the replaceable venturi ring comprises an attachment disk.

6. The evaporator of claim 1 , wherein the replaceable venturi ring comprises one or more attachment hooks.

7. The evaporator of claim 6 , wherein the one or more attachment hooks comprise a substantial harpoon like shape.

8. The evaporator of claim 6 , wherein the one or more attachment hooks comprise a groove therein for flexibility.

9. The evaporator of claim 6 , wherein the one or more attachment hooks comprise a semi-rigid plastic.

10. The evaporator of claim 6 , wherein the fan housing comprises one or more fan attachment apertures to mate with the one or more attachment hooks.

11. The evaporator of claim 6 , wherein the one or more attachment hooks comprises three attachment hooks.

12. The evaporator of claim 1 , wherein the replaceable venturi ring comprises a fan body sized to accommodate the replaceable fan.

13. The evaporator of claim 12 , wherein the fan body comprises a tapered shape.

14. An evaporator, comprising:
an evaporator housing, the evaporator housing comprising a top panel and a bottom drain pan;
a coil assembly mounted within the evaporator housing;
a fan housing with a fan aperture, wherein the fan housing comprises a grill and four edges extending from the grill into the evaporator housing, wherein the fan housing and grill are together slidably removable from the evaporator housing, and wherein the fan aperture is located in a top panel of the fan housing;
a replaceable fan positioned within the fan aperture of the fan housing, wherein the replaceable fan is configured to direct airflow out of the fan housing through the grill; and
a replaceable venturi ring sized to accommodate the replaceable fan;
wherein the replaceable venturi ring is attached to the fan housing via one or more attachment hooks; and
wherein the fan housing can accommodate a plurality of differently sized replaceable fans and a plurality of differently sized replaceable venturi rings.

15. The evaporator of claim 14 , wherein the replaceable fan comprises a backward incline centrifugal fan.

16. The evaporator of claim 14 , wherein the replaceable venturi ring comprises an attachment.

17. The evaporator of claim 14 , wherein the one or more attachment hooks comprise a substantial harpoon like shape.

18. The evaporator of claim 14 , wherein the one or more attachment hooks comprise a groove therein for flexibility.

19. The evaporator of claim 14 , wherein the fan housing comprises one or more fan attachment apertures to mate with the one or more attachment hooks.

20. An evaporator, comprising:
an evaporator housing, the evaporator housing comprising a top panel and a bottom drain pan;
a coil assembly mounted within the evaporator housing;
a fan housing positioned within the evaporator housing, wherein the fan housing comprises a grill and four edges extending from the grill into the evaporator housing, wherein the fan housing and grill are together slidably removable from the evaporator housing;
a replaceable backward incline centrifugal fan positioned within the fan housing, wherein the replaceable fan is configured to direct airflow out of the fan housing through the grill; and
a replaceable venturi ring sized to accommodate the replaceable backward incline centrifugal fan positioned in the fan housing via a number of harpoon shaped attachment hooks; and
wherein the fan housing can accommodate a plurality of differently sized replaceable backward incline centrifugal fans and a plurality of differently sized replaceable venturi rings;
wherein the fan housing comprises a fan aperture in a top panel of the fan housing and the replaceable venturi ring is positioned within the fan aperture.
