Refrigerator appliance chilled air system

A method of operating a refrigerator appliance, the refrigerator appliance comprising a cabinet, a fresh food chamber defined in the cabinet, a freezer chamber defined in the cabinet, the freezer chamber spaced apart from the fresh food chamber and separated from the fresh food chamber by an insulated mullion, a bridge chamber defined in the cabinet, the bridge chamber positioned between the fresh food chamber and the freezer chamber, the bridge chamber comprising a first inlet in fluid communication with the fresh food chamber, a first outlet in fluid communication with the fresh food chamber, a second inlet in fluid communication with the freezer chamber, and a second outlet in fluid communication with the freezer chamber, the refrigerator appliance further comprising a movable damper assembly, an evaporator positioned in the bridge chamber, and a fan positioned in the bridge chamber, wherein the movable damper assembly comprises a single curved damper, the single curved damper comprising an inlet and an outlet, wherein the inlet is oriented towards the first inlet in the first position and the inlet is oriented towards the second inlet in the second position, and wherein the outlet is oriented towards the evaporator in the first position and in the second position, the method comprising:

• moving the single curved damper of the movable damper assembly to a first position, whereby at least one of the second inlet and the second outlet is obstructed by the single curved damper of the damper assembly in the first position;
• guiding, by the single curved damper, a flow of air from the fresh food chamber towards the evaporator while the damper assembly is in the first position;
• moving the movable damper assembly to a second position, whereby at least one of the first inlet and the first outlet is obstructed by the single curved damper of the damper assembly in the second position;
• and
• guiding, by the single curved damper, a flow of air from the freezer chamber towards the evaporator while the damper assembly is in the second position.
