Abstract: An exemplary walk-in refrigeration system comprises an insulated compartment. A supply plenum is disposed between a roof insulation wall and a ceiling panel. A pair of opposing wall plenums are respectively defined between a corresponding lateral insulation wall and a corresponding interface wall. Each wall plenum is in airflow communication between the supply plenum and a respective shelf refrigeration zone. A walk-in zone is disposed between the shelf refrigeration zones. The interface walls each include a plurality of flow discharge ports which direct airflow from the respective wall plenum to the respective shelf refrigeration zone. Each interface wall may comprise an array of removable and replaceable interface panels. The interface panels may each include a vent segment with one or more capture inlet ports. An actuatable metering element on the vent segment may allow a user to selectably restrict airflow through the capture inlet ports independently for each interface panel.
