A system-level fault detection and diagnostic (FDD)
method for heating, ventilation and air conditioning
(HVAC) systems was developed. It functions as an
interface between multiple, equipment-specific FDD tools
and a human operator. The method resolves conflicting
fault reports from equipment-specific FDD tools,
performance FDD at the system level and presents an
integrated view of an HVAC system's fault status to an
operator. A simulation study to test and evaluate the
method was conducted.
