Fault Detection System Using Directional Classified Rule-Based in AHU

Monitoring systems used at present to operate air handling unit (AHU) optimally do not have a function that enables to detect faults properly when there are faults of such as operating plants or performance falling, so they are unable to manage faults rapidly and operate optimally. In this paper, we have developed a fault detection system, directional classified rule-based, which can be used in AHU system. In order to experiment this algorithm, it was applied to AHU system which is installed inside environment chamber(EC), verified its own practical effect, and confirmed its own applicability to the related field in the future.
