Design of a steady-state detector for fault detection and diagnosis of a residential air conditioner.
Author(s) : KIM M., YOON S. H., DOMANSKI P. A., et al.
Type of article: Article, IJR article
Summary
This paper presents a general methodology for developing a steady-state detector for a vapour compression system based on a moving window and using standard deviations of seven measurements selected as features. The feature thresholds and optimized moving window size were based upon steady-state no-fault tests and startup transient tests. The study showed that evaporator superheat and condenser subcooling were sufficient for determining the onset of steady-state during the startup transient. However, they misidentified steady-state during indoor temperature change tests where evaporator saturation temperature and air temperature change across the evaporator were needed for proper steady-state identification. Hence, the paper recommends including all fault detection and diagnosis features in the steady-state detector to ensure the robustness of the detector because different features may play key roles with different transients.
