Abstract:Supply/return fans and Variable Air Volume (VAV)
boxes are key components of Heating Ventilation and Air
Conditioning (HVAC) systems. Fans deliver conditioned air to
rooms and VAV boxes control airflow rates to satisfy human
thermal comfort and ventilation requirements. Faults in these
components and their sensors may lead to high energy
consumption and poor thermal comfort. Identifying failure
modes and their severities is thus critical in guiding maintenance
crew to know what, where and how severe the faults are.
Diagnosing faults of components and sensors is difficult because
