Abstract
A refrigerated merchandiser includes a display case defining a product display region having an open-front isolated from the ambient air of the store by means of a downwardly directed inner air curtain of relatively cold refrigerated air and a downwardly directed outer air curtain of relatively warmer air established via an improved curtain air admission assembly. The curtain air admission assembly defines a plenum atop the refrigerated display through which the flow of air substantially reverses direction when passing from a first flow passage to a second flow passage. This reversal of flow direction serves to distribute the air flow more uniformly along the length of the display case.
