REFRIGERATOR DOOR/WINDOW

摘要

Refrigerator doors (which includes freezer doors) are provided for use in display areas where refrigerated merchandise (e.g., frozen or chilled food) is displayed. It is desired to increase energy efficiency of the doors and thus of the refrigerated display system, while at the same time reducing visible reflectance from the doors to make it easier for customers to see merchandise which is being displayed behind the transparent doors. Refrigerator doors according to certain example embodiments of this invention include one or more AR coatings, some of which may include a transparent conductive layer (e.g., ITO) so as to also function as a low-E coating.

主权项

1. A transparent refrigerator door/window comprising:
at least first and second glass substrates of the refrigerator door, the refrigerator door being attached to a refrigerator housing a refrigerated environment; a sputter-deposited combination anti-reflective and low-E coating on an interior surface of the first glass substrate, so that the sputter-deposited coating is not exposed to the refrigerated environment adjacent the refrigerator door/window or a room environment adjacent the refrigerator door/window; wherein the sputter-deposited coating comprises a transparent conductive layer comprising indium-tin-oxide (ITO) that is located between at least a dielectric layer comprising silicon oxynitride and a dielectric layer comprising silicon oxide, and wherein the dielectric layer comprising silicon oxynitride is located between at least the first glass substrate and the transparent conductive layer comprising ITO.
