Abstract
A vehicle heating and cooling system has a distribution duct separated into two channels by a baffle for supplying separate air streams to the passenger and driver sides of the vehicle compartment. Two temperature control doors associated with the heater core and evaporator separately admit an air mix to the two channels for independent control of driver and passenger side temperature. Optionally a single door is used in place of the two temperature control doors so that at the time of manufacture the system can be configured as a single zone system. A rear air discharge opening is provided in one of the channels to supply a duct leading to the rear seat region of the vehicle compartment.
