Table 6 Details of G36-5wk fault scenarios.
From: Labeled Datasets for Air Handling Units Operating in Faulted and Fault-free States
Fault type | Fault intensity | Method of fault imposition |
|---|---|---|
Cooling coil valve stuck position | Fully closed | Defining the leakage ratio as: \(l=\frac{\kappa \upsilon (y=0)}{\kappa \upsilon (y=1)},\) where \(\kappa \upsilon (y=0)\) and \(\kappa \upsilon (y=1)\) are the flow coefficient at the fully closed and fully open positions, respectively. |
Outdoor air damper stuck position | Fully open | |
Supply duct leakage | 20% | Implementing the mathematical expression as: \({\dot{m}}_{{EF}}+{\dot{m}}_{L}=k\sqrt{\triangle p}\), where \({\dot{m}}_{{EF}}\) is the normal operation mass flow rate, \({\dot{m}}_{L}\) is the leakage mass flow rate, k is the friction factor, and \(\triangle p\) is the pressure drop. |
