Abstract
A refrigeration case includes a housing having a top and a rear wall and defining an interior chamber, a door pivotably coupled to the housing opposite the rear wall and operable to selectively open and close the interior chamber, a first shelf positioned proximate a lower portion of the interior chamber, a second shelf positioned above the first shelf, a duct wall, a fan, and a diverter. The duct wall at least partially defines a flow channel extending between the first shelf and the second shelf. The duct wall includes a first opening above the first shelf and a second opening above the second shelf. The fan provides cool air flow and is in fluid communication with the flow channel. The diverter is positioned in the flow channel proximate the second shelf and directs air flow through the second opening and over the second shelf.
