Abstract

A refrigerator display cabinet includes a refrigerated chamber having at least one transparent display window. A condenser and a compressor are positioned below the refrigerated chamber, and a fan draws exterior air through the condenser to thereby warm the air and then directs the warm air to the compressor. A deflector diverts a portion of the flow of warm air from the condenser to the compressor into a duct including a first duct portion extending horizontally from the deflector above the compressor. The dimension of the first duct portion in a direction transverse to the direction of air flow progressively decreases away from the deflector. The first duct portion opens laterally along one entire side thereof. A second duct portion is connected to and extends upwardly from the open side of the first duct and opens in a direction toward the outer surface of the display window. As a result, the diverted portion of the warm air passes horizontally through the first duct portion above the compressor and then passes upwardly through the second duct and is discharged therefrom across the outer surface of the display window, thereby preventing the formation of condensation on the display window.
