摘要： An apparatus and method for providing a partial recirculation mode of operation in an HVAC control system of a vehicle to place a fresh air passage, a recirculation passage, and an interior passage in fluid communication to reduce vehicle door closing energy by allowing external discharge of cabin air pressure from the interior passenger compartment through the fresh air passage during vehicle door closure. The partial recirculation mode bypasses distribution vent covers, distribution ductwork, heater and evaporator cores, and blowers in order to open a more direct air outlet path to atmosphere which can be activated as required in order to reduce vehicle door closing energy. The partial recirculation mode of operation is activated in response to predetermined vehicle conditions, such as, ignition switched off seat belt unbuckled, transmission switched to park, emergency brake applied, vehicle door opened, vehicle door unlocked, and/or vehicle seat sensor switched to unoccupied.
