Zusammenfassung:The invention relates to a driven turbocompressor of an air conditioning system, comprising a compressor (12) which is connected to an air intake duct (14) and to an inlet (112) of a cabin of a vehicle, and is configured to receive air from the air intake duct (14), to compress it and to provide it to the cabin, a motor (16) that is configured to drive the compressor (12) and is surrounded by a casing (18), a recovery turbine (26) that is configured to expand the cabin air (24) coming from an outlet (114) of the cabin. The device is characterized in that it comprises a cooling duct (32) configured to receive at least part of the expanded air (28) so as to cool the casing (18) of the motor and the motor (16).
