Abstract

A door for a refrigerated merchandiser defining a product display area. The door includes a first glass panel, a second glass panel, and a third glass panel. The first glass panel is in communication with an environment surrounding the merchandiser, and has a first surface facing the environment and a second surface opposite the first surface. The second glass panel has a third surface facing the second surface and a fourth surface opposite the third surface. The third glass panel is in communication with the product display area, and has a fifth surface that faces the fourth surface and a sixth surface that is opposite the fifth surface. The door also includes a film that has a split silver low-emissivity coating covering at least a portion of one or more of the first glass panel, the second glass panel, and the third glass panel.

Claims

1. A door for a refrigerated merchandiser defining a product display area, the door comprising:

a glass assembly including

a first glass panel adapted to be in communication with an environment surrounding the refrigerated merchandiser, the first glass panel having a first surface arranged to face the environment and a second surface opposite the first surface,

a second glass panel positioned adjacent the first glass panel, the second glass panel having a third surface arranged to face the second surface and a fourth surface opposite the third surface, and

a third glass panel positioned adjacent the second glass panel and adapted to be in communication with the product display area, the third glass panel having a fifth surface arranged to face the fourth surface and a sixth surface opposite the fifth surface and arranged to face the product display area;

a first film covering at least a portion of the second surface, the first film including a split silver low-emissivity coating;

a second film covering at least a portion of the fourth surface, the second film including a

split silver low-emissivity coating; and

a third film covering at least a portion of the fifth surface, the third film being a conductive film configured to be connected to a power supply to heat the third glass panel and to at least one of inhibit and remove condensation on at least one of the first glass panel and the third glass panel.

2. The door of claim 1, wherein each of the first glass panel and the third glass panel includes tempered glass, and wherein the second glass panel includes annealed glass.

3. A refrigerated merchandiser comprising:

a case defining a product display area for supporting food product;

a power supply;

a refrigeration system in communication with the case; and

at least one door coupled to the case, the at least one door including

a glass assembly having a first glass panel in communication with an ambient environment surrounding the case, a second glass panel, and a third glass panel in communication with the product display area such that the second glass panel is positioned between the first glass panel and the third glass panel, the at least one door further including

a first film covering at least a portion of the first glass panel and including a split silver low-emissivity coating,

a second film covering at least a portion of the second glass panel and including a split silver low-emissivity coating, and

a third film covering at least a portion of the third glass panel, the third film being a conductive film and the power supply in electrical communication with the third film to heat the third glass panel and at least one of inhibit and remove condensation on at least one of the first glass panel and the third glass panel.

4. The refrigerated merchandiser of claim 3, wherein the first glass panel includes a first surface arranged to face the ambient environment and a second surface opposite the first surface, and wherein the first film at least partially covers the second surface.

5. The refrigerated merchandiser of claim 4, wherein the second glass panel includes a third surface arranged to face the second surface and a fourth surface opposite the third surface, and wherein the second film at least partially covers the fourth surface.

6. The refrigerated merchandiser of claim 5, wherein the third glass panel includes a fifth surface arranged to face the fourth surface and a sixth surface opposite the fifth surface and arranged to face the product display area, and wherein the third film at least partially covers the fifth surface.

7. The refrigerated merchandiser of claim 6, wherein each of the first glass panel and the third glass panel includes tempered glass, and wherein the second glass panel includes annealed glass.
