Refrigerated merchandiser with shelf air discharge

A refrigerated merchandiser comprising:

• a case defining a product display area having a customer access opening, the case including a base having an air inlet;
• a canopy disposed substantially above the product display area, the canopy including a first air outlet and a second air outlet located adjacent the first air outlet, the first air outlet and the second air outlet in communication with the product display area;
• a first passageway fluidly connecting the air inlet with the first air outlet to direct a first airflow through the first air outlet across at least a portion of the customer access opening, the first airflow discharged from the first air outlet defining a primary long throw air curtain;
• a second passageway fluidly connecting a HVAC system with the second air outlet by ducting connected to one or more distribution ducts of a retail setting, the ducting coupled between the merchandiser and the HVAC system to direct a second airflow ducted from the HVAC system to the merchandiser through the second air outlet across at least a portion of the customer access opening, the second airflow discharged from the second air outlet defining a secondary long throw air curtain, the primary long throw air curtain and the secondary long throw air curtain cooperating with each other to maintain an upper portion of the product display area within a predetermined temperature range;
• a shelf coupled to the case within the product display area and including a third air outlet in communication with the product display area;
• and
• a third passageway in fluid communication with the third air outlet to direct a third airflow through the third air outlet across a portion of the customer access opening, the third airflow discharged from the third air outlet defining a primary short throw air curtain located inside the primary long throw air curtain, the primary long throw air curtain, the secondary long throw air curtain, and the primary short throw air curtain cooperating with each other to maintain a lower portion of the product display area within the predetermined temperature range,
• wherein the first airflow is defined by a refrigerated airflow and the second airflow is warmer than the first airflow.

• a shelf coupled to the case within the product display area for supporting food product;
• a first passageway fluidly connecting the air inlet with the first air outlet to direct a first refrigerated airflow through the first air outlet across at least a portion of the customer access opening, the first refrigerated airflow discharged from the first air outlet defining a primary air curtain;
• a second passageway fluidly connecting a HVAC system with the second air outlet by ducting connected to one or more distribution ducts of a retail setting, the ducting coupled between the merchandiser and the HVAC system to direct a second airflow through the second air outlet across at least a portion of the customer access opening, the second airflow discharged from the second air outlet defining a secondary air curtain;
• a first fan coupled to the case and in fluid communication with the first passageway to generate the first refrigerated airflow;
• and
• a second fan located in the HVAC system and in direct fluid communication with the second passageway to generate the second airflow,
• wherein the second airflow is warmer than the first refrigerated airflow.
