The regulation is intended to take place in particular in air jet installations in motor vehicles. It comprises a manifold duct (10) fed by an external air fan (14) and a plurality of air nozzles (11) which are supplied therefrom, are in each case allocated to the seats and have variable outlet openings. The particular cooling effect set should be held constant for the passenger and be independent of the setting of the other air nozzles and of fluctuations in the external air temperature. To this end the manifold duct (10) has a pilot opening (12) with a measurement sensor, for example heating wire sensor (16), which is impinged on by the emerging air. The electrical output signal, proportional to the emerging air stream, from the measurement sensor (16) controls, via an amplifier (17), the motor (15) of the external air fan (14) for holding constant the air pressure in the manifold duct (10). <IMAGE> |
