Résumé

An experimental study has been performed to develop a method for fault detection and diagnosis (FDD) in a vapour compression refrigeration system. The study is aiming at finding out efficient rules of diagnosis for easy determination of abnormal operation of a refrigeration system. The refrigeration system was operated with a variable speed compressor to modulate cooling capacity. Four major faults were considered, and each fault is detected by separating the system response to the load change in a variable speed compressor system. The FDD system was designed to consider different situations while the system satisfies necessary air-conditioning load. Rule-based method was used to diagnose and classify the system faults. The method developed can be used in the fault detection of a refrigeration system with a variable speed compressor. From the experimental results, COP degradation due to the fault of a variable speed system is severer than that in a constant speed system.
