Zone cooling in a refrigerated merchandiser

A refrigerated merchandiser comprising:

• a case defining a product display area and a customer access opening, the case including an air inlet and an air outlet in communication with the product display area;
• a passageway fluidly connecting the air inlet with the air outlet to direct a refrigerated airflow through the air outlet across at least a portion of the customer access opening in the form of a primary air curtain;
• and
• a shelf including an inlet disposed adjacent a rear of the shelf, a first outlet disposed adjacent a front of the shelf, and one or more second outlets disposed along the sides of the shelf and in fluid communication with the inlet to form a three-sided secondary air curtain discharged into the product display area to provide independent zone cooling to a particular region of the product display area.

• and
• a shelf coupled to the case within the product display area to support product and to receive a portion of the airflow from the passageway, the shelf including a fan unit to draw air from the passageway into the shelf and a heat exchanger positioned to condition the airflow prior to the airflow being discharged from the shelf in the form of a three-sided secondary air curtain to provide an independent cooling zone within the product display area.
