Air blower especially for air conditioning system in motor vehicle has delivery characteristic variable between dispersion characteristic and spot characteristic, whereby delivery characteristic is altered by adjustable swirl

摘要

The air blower, especially for a motor vehicle, has a delivery characteristic variable between a dispersion characteristic (12) and a spot characteristic (13), whereby the delivery characteristic is altered by an adjustable swirl during the delivery of at least one air stream (20). The swirl of the air stream is adjustable between a maximum value during the dispersion characteristic and a minimum value during the spot characteristic. The swirl is adjustable by altering the air ducting and/or air volume and/or air velocity and/or flow direction of the air stream. An independent claim is included for an air conditioning system in a motor vehicle equipped with at least one aforesaid air blower.
