Abstract
When operating a complex facility, Fault Detection and Diagnosis (FDD) system is beneficial in equipment management by providing the operator with tools which can help find out a failure of the system. In this research, FDD algorithm was developed using the general pattern classifier method that can be applied to absorption chiller system. The simulation model for absorption chiller system was developed in order to obtain characteristic data of absorption chiller system under normal and faulty operation. We tested FDD algorithm of absorption chiller using simulation model data. In this research, we presented fault detection method using a normalized distance. Sensitivity analysis of fault detection was carried out with respect to fault progress. FDD algorithm developed in this study was found to indicate each failure modes accurately.
