A method and a device for operating a refrigerant system in an air conditioning unit for an automobile, in which air flowing through an evaporator is cooled via a refrigerant, the delivery rate of which is set by means of a compressor operated by a drive. The speed of the drive, operated independently of the automobile engine, is determined as a function of a suction pressure to be set on the compressor, thereby providing optimal energy consumption by the system.
