Summary

Recent market trend of eco-friendly products let the manufacturers be ready for the high quality of maintenance technologies to assure the system’s high efficiency during its entire life span. However, this post-manufacturing activities burden the manufacturer with high warranty cost. Therefore, in order to promote economical businesses, the manufacturers are developing various fault detection and diagnosis (FDD) technologies. This paper presents a general design methodology of the steady-state detector (SSD) which is the preemptive core logic of fault detection and diagnosis (FDD) module. The logic of moving window (MW) and decomposition analysis technique (DAT) is embedded in the SSD. Using the MW and DAT, the SSD can detect steady states independently for each component in a system. This independent detection of steady state in a component level provides different perspectives to understand the steady state of the heat pump system which has multiple indoor units.
