Abstract
A cooled display case includes a housing enclosing a display compartment and having an opening providing access thereinto. An air stratifier panel divides the display compartment into an upper air well above the stratifier panel and a lower air well below the stratifier panel. The stratifier panel has a plurality of product holders capable of holding the products with the upper ends thereof above the stratifier panel in the upper air well. The stratifier panel also has air vents adjacent its edge for permitting cooled air to flow from the upper to lower air wells. An air recirculation passageway in the housing has an inlet in the lower air well of the display compartment and an outlet in the upper air well. A coil cools air passing through the passageway. A fan circulates the cooled air through the passageway and into the upper air well of the display compartment.
