Abstract

Refrigeration system has a display case defining a display space. The display space has a top area, a bottom area, a front viewing area, and a back area. A cooling element provides cool air to display space. An air outlet directs a cool air curtain to an air inlet, across the front viewing area. A light source is located near the back area away from the air curtain. A reflector is spaced from the light source and reflects light through the display space.

Claims

1. A refrigeration system comprising:

a display case defining a display space having a top area, a bottom area, a front viewing area, and a back area;

a cooling element in communication with said display space;

at least one air outlet in communication with said cooling element, said at least one air outlet for guiding an air curtain across said front viewing area; and

a reflector spaced from a light source and located proximate said front area, with said light source spaced toward said back area from said reflector, said reflector for reflecting light through said display space.

2. The refrigeration system of claim 1 including a shelf within said display space wherein said reflector is mounted to said shelf.

3. The refrigeration system of claim 2 including an air mover directing air from said cooling element to said air outlet.

4. The refrigeration system of claim 3 wherein said air mover comprises a fan.

5. The refrigeration system of claim 1 including an air inlet in communication with said air outlet, said air inlet for receiving said air curtain.

6. The refrigeration system of claim 1 wherein said reflector comprises a mirror.

7. The refrigeration system of claim 1 wherein said reflector comprises a reflective tape.

8. The refrigeration system of claim 1 wherein said light source is located proximate said back area.

9. A method of refrigeration comprising:

providing a display space having a front viewing area and a back area;

cooling air for the display space;

directing the cool air across the front viewing area;

locating a light source away from the front viewing area spaced toward the back area;

spacing a reflector from the light source;

directing light from the light source to the reflector; and

reflecting light into the display space from the reflector.

10. A refrigeration system comprising:

a display case defining a display space having a front viewing area and a back area;

a cooling element in communication with said display space;

at least one air outlet in communication with said cooling element, said at least one air outlet for guiding an air curtain across said front viewing area;

a first shelf within said display space wherein a reflector is mount on said first shelf; and

a light source for emitting light from said back area to said reflector long said first shelf.

11. The refrigeration system of claim 10 including a second shelf spaced below said first shelf wherein said reflector is angled to reflect light on said second shelf.

12. The refrigeration system of claim 11 wherein said light source is located above an anticipated height of a product on said second shelf.
