Refrigerated merchandiser with shelf air discharge

A refrigerated merchandiser comprising:

• a case defining a product display area having an opening, the case including a base having an air inlet located adjacent the product display area;
• a canopy disposed substantially above the product display area, the canopy having an air outlet located adjacent the product display area;
• a primary passageway fluidly connecting the air inlet with the air outlet to direct a first refrigerated airflow from the air outlet across the opening in the form of a primary air curtain;
• a shelf coupled to the case within the product display area;
• and
• a duct apparatus removably coupled to the shelf and in fluid communication with the primary passageway, the duct apparatus including an air discharge located adjacent an end of the shelf and defining a secondary passageway between the primary passageway and the air discharge to direct a second refrigerated airflow from the duct apparatus into the product display area below the canopy in the form of a secondary air curtain, the primary air curtain cooperating with the secondary air curtain to define a sequential air curtain to maintain an upper portion of the product display area and a lower portion of the product display area within substantially the same temperature range.

• a duct apparatus removably coupled to the shelf and in fluid communication with the primary passageway, the duct apparatus including an air discharge in communication with the product display area and defining a secondary passageway between the primary passageway and the air discharge;
• a first air curtain discharged from the canopy and defining a long throw air curtain to direct a refrigerated airflow generally downward from the first air outlet toward the air inlet;
• a second air curtain discharged from the duct apparatus and spaced inward from the first air curtain, the second air curtain defining a short throw air curtain to direct a refrigerated airflow generally downward from the air discharge adjacent the shelf toward the air inlet;
• and
• a third air curtain discharged from the canopy and spaced outward from the first air curtain, the third air curtain defining a long throw air curtain to direct an airflow generally downward from the second air outlet toward the air inlet, the first, second, and third air curtains cooperating with each other to maintain an upper portion of the product display area and a lower portion of the product display area within substantially the same temperature range.
