1. A refrigerated merchandiser comprising:
a case defining a product display area and including a base, a lower flue, a first air passageway, and a second air passageway, the first air passageway and second air passageway in fluid communication with the lower flue and with the product display area; an evaporator positioned in the first air passageway; a fan assembly with a single fan positioned in the base in fluid communication with the lower flue to generate an airflow; and a fan plenum into which the fan assembly is disposed, the fan plenum including an airflow divider to direct a first portion of the airflow to the first air passageway and to direct a second portion of the airflow to the second air passageway, wherein the proportion of air between the first portion and the second portion is a function of a position and geometry of the airflow divider, wherein the fan plenum includes a top wall, a side wall, and a plenum base, and wherein the airflow divider partitions the fan plenum into a first duct and a second duct, the first duct in communication with the first air passageway and the second duct in communication with the second air passageway, wherein the airflow divider includes a first wall member and a second wall member, wherein the first wall member and the second wall member operably separate the first duct from the second duct, and wherein the first wall member and the second wall member are orthogonal to the top wall, and further wherein an angular separation α of the first wall member from the second wall member ranges from about 45° to about 180°, wherein an increase in α decreases the proportion of air between the first portion and the second portion of the airflow. |
