Electric Steam Humidifier
This equipment represents an electrically heated, self-contained, steam humidifier. It 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 is controlled to meet the humidity ratio set point of the supply air defined by the associated system humidity controller.

Rated Water Flow Rate
|
Default: Auto Size
|
|
Typical Range: 0.01 to 0.25 gpm
|
|
Min/Max: 0 to 1,000,000,000,000,000 (this field cannot be left blank)
|
|
Units: gpm; m3/hr; L/s; m3/s
|
This numeric input is the volumetric water flow rate through the humidifier at rated conditions (water entering the dehumidifier at 5.05°C [41.1°F] in m3/s [gpm]).
Rated Power
Default Value: Auto Size box checked
|
Default: Auto Size
|
|
Typical Range: 2 to 34 kW
|
|
Min/Max: 0 to 1,000,000,000,000,000 (this field cannot be left blank)
|
|
Units: W; kW; Btuh; MBh
|
This field describes the power consumption of the unit, but does not include the electrical consumption of the fan or any standby electrical loads. When the Auto Size option is selected for this field, the rated power value is calculated based upon the value input for the Rated Water Flow Rate and the enthalpy rise of the supplied water from a reference temperature of liquid water at 20°C [68°F] to a saturated steam at 100°C [212°F].
Standby Power
|
Default: 0 W
|
|
Typical Range: Need to source data
|
|
Min/Max: 0 to 1,000,000,000,000,000 (this field cannot be left blank)
|
|
Units: W
|
This input represents the electrical energy draw associated with this object whenever the schedule for the system it is assigned to indicates that it is available to operate (i.e. regardless of whether or not the humidifier is operating).
Fan Rated Power
|
Default: 0 hp
|
|
Typical Range: 0.0001 to 0.0004 kW/(cfm)
|
|
Min/Max: 0 to 1,000,000,000,000,000 (this field cannot be left blank)
|
|
Units: W; kW; hp
|
This field represents the nominal full output energy consumption of the blower fan for the humidifier.
