Abstract
An apparatus and system and method for mixing airflow and draining condensate in a duct exposed to sub-freezing air are disclosed. An example mixing duct apparatus includes a recirculation duct and a pack duct having a first end and a second end. The first end of the pack duct is coupled to a side of the recirculation duct. The pack duct has a lip that extends into an airflow passage defined by the recirculation duct. This lip defines a flow channel for condensate in the recirculation duct to flow beneath sub-freezing air entering the recirculation duct from the pack duct to decrease ice build-up in the pack duct.
