An air return duct and air return duct grille (400;500) for a chiller in an aircraft galley has articulated slats (402;502) that are biased to open during chilling cycles and close during defrost cycles. In the closed orientation, the articulated slats divert any condensate from the chiller to a collection hose; in the open orientation, the articulated slates allow unrestricted airflow. The articulated slats may include a passive biasing element to bias the articulated slats into an open or closed orientation as necessary. The air return duct may also include air return duct grills without articulated slates to allow unobstructed air flow when the articulated slats are in a closed orientation.
