ABSTRACT:
A refrigerated showcase in which refrigerated air for refrigerating the interior of the showcase and preventing ambient air from invading in the showcase is circulated across a front opening of the showcase and through a bottom wall, a rear wall and a top wall of the showcase, is improved according to the present invention. The improvements reside in that a gas-permeable spacer is disposed at the end of shelves within the showcase and spaced from the front surface of the rear wall to form a refrigerated air introducing duct space between the spacer and the rear wall.
