A refrigerator having a storage area for holding and displaying goods to be refrigerated including means for defrosting the coils in the refrigeration system by exposing a portion of the system to the ambient atmosphere. An air flow path is defined in the refrigerator in conjunction with the refrigeration system to refrigerate the goods on display. A closure means which carries a portion of the system is integrated with baffle means to close at least part of the air flow when the closure means is moved to an open position. In the open position the coils are defrosted by exposure to the ambient air, while some cooler air is prevented by the baffle means from being drawn out of the refrigerator.

A refrigerated case, comprising: an outer cabinet; an inner cabinet spaced from said outer cabinet; air flow duct means for conveying a flowing airstream around at least a substantial portion of the exterior of the inner cabinet; a plenum chamber between said inner and outer cabinets communicating with said duct means, said plenum chamber having a closable opening for communicating said plenum chamber with the ambient atmosphere; closure means mounted to said case and moveable between at least closed and open positions with respect to said closable opening for closing said plenum chamber from and opening said plenum chamber to communication with the ambient atmosphere; air circulating and cooling means mounted to said closure means, such that, in the closed position of said closure means, said air circulating and cooling means are disposed in said plenum chamber for drawing air through said cooling means and propelling said cooled air through said duct means around said inner cabinet, and, in the open position of said closure means, said air circulating and cooling means are exposed to the ambient atmosphere; and baffle means coupled with said closure means for closing off said duct means from communication with said plenum chamber when said closure means is in said open position and for opening communication between said plenum chamber and said duct means when said closure means is in said closed position.
