Claim 18:
19. A thermal system comprising:
a housing that defines an intake flow path for travel of intake airflow and an exhaust flow path for travel of exhaust airflow;
a heat exchanger that is disposed in the housing, the heat exchanger occupying a portion of the intake flow path and a portion of the exhaust flow path; and
a mode door disposed in the housing upstream of the heat exchanger, the mode door having:
a first position configured to route the intake airflow through a portion of the intake flow path not occupied by the heat exchanger and configured to route the exhaust airflow to pass through the heat exchanger;
a second position configured to route the exhaust airflow through a portion of the exhaust flow path not occupied by the heat exchanger and configured to route the intake airflow to pass through the heat exchanger; and
a third position between the first position and the second position, the third position configured to route the intake airflow and the exhaust airflow to pass through the heat exchanger.
