Abstract

A refrigeration system comprises a display case having a viewing area with the first side and a second side. An air outlet on the first side guides air across the viewing area to an air inlet on the second side. A first fan and a second fan communicate with the air inlet. A volume extends between the air inlet and the first and second fans. The partition divides this volume between the first and second fan.

Claims (37)

1. A refrigeration system comprising:

a display case having a viewing area with a first side and a second side;

an air outlet on said first side, guiding air across said viewing area;

an air inlet on said second side, receiving air from said air outlet;

at least a first fan and a second fan in communication with said air inlet;

a first volume extending between said air inlet and said first fan and second fan; and

at least a first partition between said first fan and said second fan, dividing said first volume.

2. The refrigeration system of claim 1 including a cooling element spaced from said first fan and said second fan cooling air received from said air inlet.

3. The refrigeration system of claim 2 including a second partition between said first fan and said second fan extending into a second volume between said first fan and said second fan and said cooling element.

4. The refrigeration system of claim 1 including a first panel supporting said first fan and said second fan within said display case.

5. The refrigeration system of claim 4 wherein said first partition extends generally perpendicular from said first panel.

6. The refrigeration system of claim 4 including a second panel spaced from said first panel to define at least partially said first volume.

7. The refrigeration system of claim 1 wherein said first fan and said second fan spin in the same direction.

8. A refrigeration system comprising:

a display case having a viewing area with a first side and a second side;

an air outlet on said first side, guiding air across said viewing area;

an air inlet on said second side, receiving air from said air outlet;

at least a first fan and a second fan supported by a first panel, spinning in the same direction and in communication with said air inlet;

a cooling element spaced from said first fan and said second fan, cooling air received from said air inlet;

a first volume extending between said first fan and said second fan and said cooling element; and

at least a first partition between said first fan and said second fan, dividing said first volume.

9. The refrigeration system of claim 8 including a second volume extending between said air inlet and said first fan and said second fan.

10. The refrigeration system of claim 9 including a second partition between said first fan and said second fan extending into a second volume between said first fan and said second fan and said air inlet.

11. The refrigeration system of claim 8 wherein said first partition extends generally perpendicular from said first panel.

12. The refrigeration system of claim 8 including a second panel spaced from said first panel to define at least partially said first volume.

13. A refrigeration system comprising:

a display case having a viewing area with a first side and a second side;

an air outlet on said first side, guiding air across said viewing area;

an air inlet on said second side, receiving air from said air outlet;

at least a first fan and a second fan in communication with said air inlet;

a cooling element spaced from said first fan and said second fan to at least partially defining a first volume, cooling air received by said air inlet;

at least a first partition between said first fan and said second fan, dividing said first volume.

14. The refrigeration system of claim 13 including a second volume extending between said air inlet and said first fan and second fan wherein said second volume is divided by a second partition between said first fan and said second fan.

15. The refrigeration system of claim 13 including a first panel supporting said first fan and said second fan within said display case.

16. The refrigeration system of claim 15 wherein said first partition extends generally perpendicular from said first panel.

17. The refrigeration system of claim 15 including a second panel spaced from said first panel to define at least partially said first volume.

18. The refrigeration system of claim 13 wherein said first fan and said second fan spin in the same direction.
