Abstract：
Aiming at the faults of variable-air-volume terminals, puts forward a fault detection and diagnosis method, and develops the fault diagnosis software. This software uses Cumulative Sum (CUSUM) control charts to detect faults, and uses a rule-based fault classifier to find fault sources. An online application shows the software is reliable and helpful in improving maintenance efficiency, indoor thermal comfort and energy efficiency.
