The invention relates to a system for the prevention of icing in a conduit, as can occur in, for example, a conduit of an aircraft air conditioner. The system according to the invention has at least one sensor (10) for detecting mechanical conduit vibrations, an electronic evaluation unit, and an electronic control unit (14), wherein the at least one sensor is connected to the electronic evaluation unit (18), the evaluation unit has characteristic data of the vibratory behavior of the conduit and is set up to compare the measured conduit vibrations with the characteristic data and to make an interpretation as conduit icing by correlation, and to send out a signal to the control unit in the case of conduit icing. If the vibration of the conduit being monitored, caused by operation, is not sufficient, vibration can be stimulated or amplified by one or multiple actuators (22). With the system according to the invention, an icing condition inside the conduit can be detected without a sensor located inside the internal cross-section of the same, wherein the conduit itself serves as the sensing element. |
