Abstract

The development of the fault detection and diagnosis (FDD) system of air-conditioning systems has started as one of IEA-Annex 25 activities. Recently, FDD-WG of the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan and IEA-Annex 34 are holding the development of the FDD system. The stochastic qualitative reasoning (SQR) provides a modelling method of human qualitative thinking process based on the instrumentation diagram and the control information of air-conditioning systems. In this paper, the simulation process of real fault data using the SQR method is reported. In the near future, the SQR will implement the automatic method of fault detection to the computer applications.
