ABSTRACT:
A refrigerated display case for food stuffs diffuses a supply of dry chilled air around and about a plurality of cold shelves to preclude the formation of frost and to defrost the display case subsequent to introduction of warmer moist air. The flow of dry chilled air is exhausted through a port located above the top shelf, whereby natural convection within the display case insures continual exhaustion of the highest temperature air.
