Fault Detection And Diagnosis Of Refrigeration System In Data Centers

5767,1508,5768

With the development of IT industry, data centers are proved to play a more and more important part. In order to make sure data centers are operating normally, it is significant to detect and diagnose faults for refrigeration system. In this paper, the features of refrigeration system’s faults and the development of refrigeration system in data centers are discussed. Furthermore, a few efficient fault detection and diagnosis (FDD) strategies are introduced and studied. The diagnosis mechanism is analyzed in detail, and the advantages/disadvantages of each strategy are pointed out. At last, a united FDD method is proposed, which is benefit for understanding the present development in the field of refrigeration system fault detection and diagnosis.
