 Connections between the air distribution unit, the supply air duct, and the zone are specified in the input syntax for the air distribution unit and the \hyperref[airloophvaczonesplitter]{AirLoopHVAC:ZoneSplitter}. The input syntax also explicitly defines an outlet identifier. This implies a connection to a zone through a \hyperref[nodelist]{NodeList} for zone inlets (see the \hyperref[zonehvacequipmentconnections]{ZoneHVAC:EquipmentConnections} statement). Each air distribution unit is essentially a combined component-controller. Since controls are normally based on the zone thermostat, they can work in parallel or series in complex fashion. Each air distribution unit operates to meet all or part of the remaining thermostat load as specified in \hyperref[zonehvacequipmentlist]{ZoneHVAC:EquipmentList}.
 
-The Air Distribution unit also allows the user to specify leaks in the supply air duct system. These inputs are used in the EnergyPlus Simplified Duct Leakage Model (SDLM). This model simulates a specific configuration: supply leaks to a return plenum in a commercial VAV or CV system. The system must have a constant static pressure setpoint. Within these limitations SDLM allows the user to easily evaluate the energy penalty due to duct leakage.
+The Air Distribution unit also allows the user to specify leaks in the supply air duct system. These inputs are used in the EnergyPlus Simplified Duct Leakage Model (SDLM). This model simulates a specific configuration: supply leaks to a return plenum in a commercial VAV or CV system. The VAV system must have a constant static pressure setpoint, and a constant upstream air leakage flow rate is calculated using the upstream leakage fraction and design flow rate of the VAV box. For the CV system, a proportional leakage amount is calculated using the upstream leakage fraction and the maximum available air flow rate of the air terminal box. The downstream leakages are always calculated as a fraction of the current flow rate through the air terminal. Within these limitations SDLM allows the user to easily evaluate the energy penalty due to duct leakage.
