Abstract: A vehicle HVAC system including a ram air throttling assembly. The ram air throttling assembly includes: a housing defining a ram air inlet, a recirculation air inlet, and an outlet; a first door within the housing, the first door movable to direct airflow from at least one of the ram air inlet and the recirculation air inlet to the outlet; and a second door slidably movable to throttle airflow into the housing through the ram air inlet.

Abstract: A heating, ventilation, and air condition (HVAC) unit includes a casing, a mount, and one or more flexible fingers. The casing is configured to condition air and direct the conditioned air to a vehicle occupant cabin. The mount extends from the casing and is configured to be mounted to an attachment surface. The mount includes an opening that has an inner surface. The flexible fingers each have a proximal end that extends from the inner surface and a distal end. One or more of the distal ends of the flexible fingers are configured to engage an attachment feature extending from the attachment surface and through the opening in the mount to secure the mount to the attachment feature.

Abstract: An HVAC case configured to heat airflow for a vehicle HVAC system. The HVAC case has a defrost outlet, a primary demist outlet, a secondary demist outlet, and an airflow control door. The airflow control door is configured to control airflow through each one of the defrost outlet, the primary demist outlet, and the secondary demist outlet.

Abstract: A vehicle airflow system includes a centrifugal fan and an air diffuser. The centrifugal fan is configured to direct air radially outward from a rotational axis of the fan. The air diffuser has a plurality of air deflectors that are disposed radially about the fan. The air deflectors have curved surfaces. Each curved surface defines an airflow channel that has an inlet extending radially outward from a periphery of the centrifugal fan and an outlet extending axially away from the diffuser relative to the rotational axis of the fan.
