A refrigerated display case having at least two outlet air conduits with a unitary grid member covering the outlet openings of such conduits. The display case is formed by a cabinet having an interior display space for holding refrigerated products. A primary air conduit encircles the cabinet and has an outlet opening at one end adjacent to an access opening in the cabinet and an inlet opening at its other end adjacent to the access opening. The inlet and outlet openings of the primary air conduit are aligned so that air leaving the outlet opening is directed across the access opening of the cabinet and received by the inlet opening. A set of evaporator coils are arranged within the primary air conduit for refrigerating the air passing through such conduits. The air is circulated through the primary air conduit by a set of fans. A secondary air conduit extends along the cabinet and is positioned outside of the primary air conduit. The secondary air conduit has an outlet opening for directing air across the access opening of the cabinet. The outlet opening of the secondary air conduit is aligned with and positioned adjacent to the outlet opening of the primary air conduit. A unitary grid member extends across the outlet opening of the primary air conduit and the outlet opening of the secondary air conduit. Due to the temperature differential between the air emitted from the outlet openings there is normally a tendency for condensation to accumulate at the juncture of the two outlet openings. In order to minimize and substantially eliminate such condensation and any resulting frost buildup, in insulating member separates the two air conduits and is either in contact with or actually extended into the unitary grid structure.
