ABSTRACT:
A refrigerated display case is disclosed which has an interior cabinet and an exterior member. A refrigerating circuit includes evaporators for refrigerating and heaters for defrosting a frost accumulated on the evaporators located forwardly of the evaporators. A circulating mechanism forces air into contact with the refrigerating circuit. A passage directs the refrigerated air. The display case is defined by a front opening for access to the interior thereof. At least two air inlets and corresponding outlets extend across opposed edges of said front opening. The passage includes at least inner and outer conduits which communicate with the respective outlets and inlets, the passage being defined between the interior cabinet and the exterior member. A circulating mechanism operates to drive separate air steams through the passage and across the front opening in an innermost stream and an outermost stream. The refrigerating mechanism is located in the inner conduit for refrigerating the innermost stream crossing the access opening. The damper mechanism merges the air stream which passes through the outer conduit into the inner conduit during operation of a defrosting mode. Therefore, the time for defrosting of evaporators can be shortened.
