Abstract:As a major component of Heating, Ventilation and
Air Conditioning systems (HVACs), an Air Handling Unit
(AHU) is used to condition and circulate air to rooms to satisfy
human comfort requirements. In an AHU, cooling coil and
supply air fan are two key components, where a cooling coil
reduces air temperature and a fan delivers air to rooms. The fan
and the cooling coil are interconnected, and a fault in one
component may cause faults in the other. To save energy and
satisfy human comfort requirements, diagnosing faults of the fan
and the cooling coil is critical. In this paper, a method based
