Zusammenfassung:	A refrigerated display case having a display space therein is provided with an access opening in the front of the case and an air curtain composed of a plurality of adjacent layers of air is directed across the access opening with the innermost layer of air adjacent the display space being at a higher temperature than an adjacent layer of air. Some of the air from the air curtain may be directed inwardly for circulation within the display space if desired. Refrigerated means are provided for refrigerating the air forming at least some of the layers of air forming the air curtain and the air forming the innermost layer of the air curtain may flow through a passage which by-passes the refrigeration means. The display space also may be provided with a rear access opening and duct means for circulation of the air forming the air curtain may have portions extending vertically upward at opposite sides of the rear access opening.
