Systems and methods for airflow management around palletized cases of goods in a warehouse storage facility are provided, in which airflow around each individual layer of cases is facilitated while airflow “spillage” around the sides, top or bottom of pallet assemblies is minimized or eliminated. One exemplary device for such airflow management includes palletized product spacers disposed between respective layers of vertically stacked cases, in which the product spacers facilitate a substantially unidirectional longitudinal airflow. Another exemplary airflow management device is a series of automatically adjustable air dams disposed at the tops of respective pallet assemblies which prevent air spillage and establish intermediate air manifold spaces. Yet another device is a lateral pallet spacer prevents direct abutment of the side surfaces of neighboring pallet assemblies and thereby ensures that the air manifold spaces are in fluid communication with the spacers of multiple pallet assemblies.
