Détection et diagnostic d'anomalies dans les installations de traitement d'air basés sur les paramètres de performance.

Performance factors as a basis of practical fault detection and diagnostic methods for air-handling units.

Auteurs : KÄRKI S. H., KARJALAINEN S. J.

Résumé

The technical term "performance" is defined as how well a system fulfils its intended purpose in different operational circumstances. The paper describes the process of establishing the performance factors of air-handling units, defining the performance requirements, and connecting them to fault detection and diagnosis methods. The most important performance requirements of air-handling units are related to heating and cooling energy, the supply airflow rate and purity, energy efficiency, and control quality. Many solutions made during different life-cycle phases affect the final system performance. These solutions are discussed.
