ABSTRACT:
A refrigerated case having an access opening for access to the interior of the case by customers in a store where the case is used. Ducts are provided in the case for circulating refrigerated air across the access opening from a discharge opening at one end of the access opening to a return aperture at the other end of the access opening. The refrigeration system used in the case includes at least one conduit carrying refrigerant at a temperature higher than that of the air bands. At least a portion of this conduit is located adjacent the discharge opening to raise the temperature of the case in the vicinity of the discharge opening sufficiently to impede the accumulation of frost.
