A Simulation Study of a Hierarchical, Rule-Based Method for System-Level Fault Detection and Diagnostics in HVAC Systems
A system-level fault detection and diagnostic (FDD) method for heating, ventilation, and air conditioning (HVAC) system 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 tolls, performs 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.
