Abstract: An open refrigerated display case comprising: a refrigerated display area comprising one or more shelves; an air outlet and an air inlet opening into the display area and spaced from one another; a duct fluidically coupling the air inlet to the air outlet, the duct being configured to direct air flow out of the air outlet across the display area and toward the air inlet to form an air curtain across the display area; wherein each of the one or more shelves are provided with an associated flow stabilizing device; wherein each flow stabilizing device comprises a pair of stabilizing beams which are spaced from one another so as to define an innermost stabilizing beam and an outermost stabilizing beam; wherein a first slot is formed between the innermost and the outermost stabilizing beams, the first slot extending transversely across the display area perpendicular to the direction of the air flow within the air curtain, the first slot having a stabilizing inlet, a stabilizing outlet and a stabilizing throat disposed therebetween; wherein the innermost stabilizing beam is spaced from the adjacent shelf so as to form a second slot between the innermost stabilizing beam and the shelf; and wherein the one or more flow stabilizing devices are each positioned so that the stabilizing inlet of the first slot receives the air curtain, the stabilizing throat being configured to stabilize the air flow within the air curtain which exits the flow stabilizing device via the stabilizing outlet.
