A multi-curtain, open front refrigerated display case having unique energy saving capacity as a result of the combination of an attached, retractable night curtain specially located between the refrigerated air curtain and the adjacent warmer guard curtain and upon which frost and ice form during closed store hours, with a reverse air defrost flow system that melts the front and ice from the curtain surface prior to retraction thereof at store opening time. |
