Climate Control System

A climate control system for a vehicle includes a front-end or first heat exchanger configured to thermally condition airflow from an environment external to a vehicle cabin, a rear-end or second heat exchanger configured to thermally condition airflow from the vehicle cabin, a recirculation path configured to return airflow from the second heat exchanger to the vehicle cabin, and an extraction path configured to vent airflow from the second heat exchanger to the environment external to the vehicle cabin. Various operational modes of the climate control system direct airflow to either the recirculation path or the extraction path.
