After the completing steps S940, microcomputer 100 judges whether parameter c ount value surpasses setting value (S950), when the time turning back to step S920, when greater than setting value, stop the operation of air exchange system 1 and control display part 150 and show on the steam line 20 and have anomaly (S960) less than setting value.
At this moment, setting value is meant that the operation output signal breaks away from the number of times of the normal output signal scope of microcomputer 100 output signals continuously, is to be enough to judge that the disengaging number of times of anomaly takes place steam line 20, and this parameter is obtained by test.
Described control method not only also is applicable to judge whether discharge duct 30 takes place among the unusual operation, can also be applicable to respectively among steam line 20 and the discharge duct 30 simultaneously.
In sum, according to air exchange system provided by the present invention and control method thereof, do not need to be provided with special device, judge the anomaly that is located at the pipe interior on the scavenge duct and change by the microcomputer output signal that is used to control fan electromotor, thereby the maintenance that makes air exchange system becomes simply, can prevent unnecessary energy loss thereupon.
