Humidifier:Steam:Electric[LINK]
The electric steam humidifier is a component that
represents an electrically heated, self contained steam
humidifier. The component uses electrical energy to convert
ordinary tap water to steam which it then injects into the
supply air stream by means of a blower fan. The actual unit
might be an electrode-type humidifier or a resistance-type
humidifier.
The humidifier model includes local control of the
humidifier unit to meet a humidity ratio setpoint on its air
outlet node. A set point manager is needed to put a setpoint
on the exit node but no other local controllers are needed.
The humidifier will add moisture to meet the humidity ratio
setpoint.

dry steam is delivered into the supply air stream. The
humidifier model includes local control of the humidifier unit
to meet a humidity ratio setpoint on its air outlet node of
the unit. A humidity set point manager is needed to put a
