Glass front, anti-condensation refrigerated display

A refrigerated display case comprising:

• a housing having a front display window with an inner surface and an outer surface, said housing having a top, a rear wall, and a base, all defining an enclosed space for display of food products;
• said base having a chamber containing a refrigeration coil and air propelling fans for propelling cooled air, an air inlet duct from said enclosed space to said chamber for flow of circulated air from said space to said chamber, and an outlet duct from said chamber to said enclosed space, oriented upwardly inside said chamber for propelling circulated air up to said top and adjacent said shelves, from said chamber to said space, and down again to said air inlet duct for cooling and recirculation;
• said top having a contour outlet at said top from said space to the exterior of said housing, out of said case, said contour outlet being oriented toward said front display window for flow of a portion of circulated cool air down across said front display window outer surface to cool said front display window outer surface and evaporate moisture therefrom for anti-condensation purposes.

A method of preventing condensation on the exterior surface of a front display window of a closed refrigerated display case having a top, a base containing an air cooling coil and air circulating fans, inlet and outlet ducts to and from said air cooling coil, ends, a rear wall and said front display window, comprising the steps of deflecting a portion of the circulating air in said case out of said case at said top and causing it to flow down across the exterior surface of said front display window to thereby prevent condensation on said exterior surface.
