A Hierarchical Rule-Based Fault Detection and Diagnostic Method for HVAC Systems

Jeffrey Schein, Steven Bushby
A rule-based, system-level fault detection and diagnostic (FDD) method for HVAC systems was developed. It functions as an interface between multiple, equipment-specific FDD tools and a human operator. The method resolves and prioritizes conflicting fault reports from equipment-specific FDD tools, 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. Jeffrey Schein is a
