A refrigeration cabinet for storage and display of frozen products for sale, the refrigeration cabinet including:
- an insulated cabinet body forming an open-topped product chamber closed by a clear lid at a top of the product chamber;
- the clear lid being movable on the insulated cabinet body between a closed position closing the product chamber and an open position on the insulated cabinet body to allow access to the product chamber from above the product chamber;
- a refrigeration unit for generating a climate control cold air stream, the refrigeration unit including an evaporator and an associated fan for generating the climate control cold air stream;
- an air circulation duct for delivering the climate control cold air stream through the product chamber, the air circulation duct having an air inlet communicating with a lower portion of the product chamber and an air outlet communicating with the product chamber above the air inlet,
- the air circulation duct including an air inlet duct formed in a side wall of the product chamber at the lower portion of the product chamber for delivery of the climate control cold air stream into the product chamber and an air outlet duct formed in the side wall of the product chamber at an upper portion of the product chamber for delivery of the climate control cold air stream out of the product chamber, the air inlet duct having an air inlet opening communicating with the product chamber and the air outlet duct having an air outlet opening communicating with the product chamber, each air duct being connected to the refrigeration unit for circulating the climate control cold airstream through the product chamber, the air inlet duct communicating with the evaporator and the associated fan is being configured to deliver air across the evaporator and into the air inlet duct for delivery into the product chamber, and the air outlet duct communicating with the evaporator to deliver air from the product chamber to the evaporator,
- the air circulation duct including an air distribution insert mounted in the product chamber, an exterior of the air distribution insert cooperating with an inner wall of the product chamber to define the air ducts;
- sealing elements extending between an exterior of a front panel and a rear panel of the air distribution insert and inner side walls of the cabinet body;
- the sealing elements dividing a space between the exterior of the air distribution insert and the inner wall of the product chamber into a lower air inlet duct below the sealing elements and an upper air outlet duct above the sealing elements;
- a number of spaced-apart air inlet openings in the front panel and the rear panel of the air distribution insert below the sealing elements;
- and
- a plurality of spaced-apart air outlet openings in the front panel and the rear panel of the air distribution insert above the sealing elements between the sealing elements and a rim at a top of the air distribution insert;
- the air circulation duct and the refrigeration unit being operable to feed cooling air through the product chamber to avoid air turbulence at the clear lid, wherein cold air is delivered into a bottom of the product chamber and gradually displaced upwardly through the product chamber and drawn out at the top of the product chamber such that a layer of warmer air tends to form immediately below the clear lid, above the air outlet, to avoid condensation and frosting on an underside of the clear lid.
