The default HVAC library does not include any OS:AirLoopHVAC:UnitarySystem configured for active dehumidification. This is a commonly used system type in high-humidity climates (e.g., Gulf Coast, Southeast US) and cannot be built by users from within the OpenStudio Application UI — the OS:Coil:Cooling:DX:TwoStageWithHumidityControlMode cooling coil required for CoolReheat dehumidification mode is not exposed through the drag-and-drop HVAC interface.
Expected behavior: The HVAC library should include a pre-wired unitary system with:
Dehumidification Control Type: CoolReheatOS:Coil:Cooling:DX:TwoStageWithHumidityControlMode cooling coilLatent Load Control: LatentOrSensibleLoadControl
This would allow users to add dehumidification-capable systems to their models without needing to edit the OSM file manually.
