Résumé

This paper presents results of lab and field evaluations of an Automatic Fault Detection and Diagnostics (AFDD) technology for advanced RTUs that provide cooling of small and medium commercial buildings. The primary focus of the technology is detecting overall performance degradation (COP and capacity) resulting from single and multiple faults. High confidence detection of the performance degradation and a low false alarm rate were demonstrated in the lab environment. Furthermore, a field evaluation of AFDD has been carried out on four state-of-the-art RTUs in two commercial sites in Florida. The RTUs were instrumented for online monitoring of performance degradation and fault diagnostics. The performance degradations caused by manually injected faults were successfully detected when they exceeded a preset threshold (e.g. 10% COP degradation).
