Abstract

Refrigeration system has a display case that defines 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 the display space through a series of fans that direct the air to an air outlet. The air outlet then directs the air to an air inlet, thereby forming an air curtain across the front viewing area. A light is located near the back area away from the air curtain. A mirror is spaced from the light and reflects light from the right source through the display space.

Claims

1. 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; and

a light source located proximate said back area.

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

3. The refrigeration system of claim 1 including an air mover for 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 a reflector spaced from said light source and located proximate said front viewing area, said reflector for reflecting light through said display space.

6. The refrigeration system of claim 5 wherein said reflector comprises a mirror.

7. The refrigeration system of claim 5 including a shelf within said display space wherein said reflector is mounted to said shelf.
