ABSTRACT:
A refrigerated display case with multiple air curtain structure is disclosed. The multiple air curtains are defined by at least two air circulating conduits. An innermost conduit is partially divided into two chambers, and an evaporator is disposed in each chamber for generating the refrigerated air. A damper device extends across the discharge opening of the two chambers for selectively controlling the opening and closing of the discharge opening, whereby either one of the evaporators may be defrosted by blocking the air flow through the chamber within which it is contained, while the refrigerated air circulation continues through the other chamber to maintain the temperature in the case.
