Passenger compartment ventilating device for vehicle, has differential pressure guided blower control adjusting operational data based on change of configuration of airway system so that pressure between compartment and system is constant

摘要

The device has a blower (10) producing air flow corresponding to operational data. An airway system is provided with several closable openings through which air flow from the blower is supplied to a passenger compartment. A differential pressure guided blower control (30) adjusts the operational data based on a change of configuration of the system so that differential pressure between the compartment and the system is constant.
