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.

In a refrigerator display cabinet including a refrigerated chamber having at least one transparent display window, a cooling system for cooling said refrigerated chamber and including a condenser and a compressor positioned below said refrigerated chamber and means for drawing exterior air through said condenser to thereby warm said air and then directing said warm air to said compressor, and means for preventing condensation from forming on said display window, the improvement wherein said condensation preventing means comprises: deflector means for diverting a portion only of the flow of warm air from said condenser to said compressor; duct means for receiving and conveying the diverted portion of said warm air and for discharging said diverted portion in a direction to pass across the outer surface of said display window; said duct means comprising a first duct extending horizontally from said deflector means above said compressor, the horizontal dimension of said first duct, in a direction transverse to the direction of air flow from said condenser to said compressor, progressively decreasing in a direction away from said deflector means, and said first duct opening laterally along one entire side thereof extending transverse to said horizontal dimension; and said duct means further comprising a second duct connected to and extending upwardly from said side of said first duct and opening in a direction toward said outer surface of said display window; whereby said diverted portion of said warm air passes horizontally through said first duct above said compressor and then passes upwardly through said second duct and is discharged therefrom across said outer surface of said display window.
