Abstract: This paper investigates the utilization of Acoustic Emission “AE” systems for monitoring faults of fans in refrigeration system. In this paper the AE counts analysis technique was implemented. A relation between Amplitude and AE hits (density of emission) was obtained in order to determine the behavior of the fault. The results showed that the fault noises are directly proportional to the AE emission with respect to the time. The results also showed that the measured AE energy produced during the fault is lower than that at the ideal case.
