Abstract
An air distribution apparatus for a vehicle includes a partition disposed within a housing which separates a first longitudinal airstream from a blower and a cooling element into first and second airstreams, each separately directed through a heater element to form first and second recombined airstreams. The partition redirects the first and second recombined airstreams to a second direction angularly disposed from the first direction of air flow to enable the first and second output airstreams to be separately transmitted to first and second separate zones within the vehicle. Independently movable blend valves are interposed in the first and second airstreams to provide independent selection of temperature of the first and second output airstreams.
