Abstract
An open top refrigerated display case having an upper display portion for displaying refrigerated products and a lower storage portion for storing refrigerated products. A cooling mechanism cools both the display portion and storage portion. The cooling mechanism establishes a refrigerated air band which encircles the display portion. This refrigerated air band is established by circulating air through an air conduit which surrounds the display portion and is positioned above the storage portion of the display case. Mounted within the air conduit is a fan and a set of evaporation coils. Air is expelled from one end of the conduit at an outlet opening located near the top of the display case and such air is propelled across the opening in the display case towards the opposite end of the case where it is received by an inlet opening of the air conduit. In this manner, an air curtain is formed across the top of the display case. During a refrigeration cycle the air passing along this air band is cooled thereby cooling the display portion of the display case. In addition, air from the air conduit is diverted after it has passed through the evaporation coils into the lower storage portion where it is directed around the storage portion and flows into the air conduit where it is recirculated by the fan within such conduit.
