Abstract

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 classified rule-based fault detection system which can be inclusively used in AHU system of a building by installation of sensor which is composed of AHU system and required low costs compare to the model based fault detection system which can be used only in a special building or 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.
