Patent ID: 7434612

Claim:
A multiple zoned air conditioning system for providing air conditioning to the interior of an automotive vehicle, said air conditioning system comprising: a fan to generate air flow; a main air conditioning module with a first heat exchanger for cooling and with a second heat exchanger for heating; and a multiple zone module; the main air conditioning module cooperating with the multiple zone module to create at least one first air flow adapted to be conditioned for temperature, said multiple zone module being interchangeably disposed with the main air conditioning module, when the multiple zone module is disposed on the main air conditioning module, the second heat exchanger engages the multiple zone module so as to allow air flow through the second heat exchanger, wherein when the multiple zone module is disposed on the main air conditioning module portions of the main air conditioning module and the multiple zone module cooperate and define: a first flow path within the main air conditioning module and a second flow path within the multiple zone module with the second heat exchanger extending into the first flow path and into the second flow path.
