Model for an air humidifier or dehumidifier.
This model adds (or removes) moisture from the air stream. The amount of exchanged moisture is equal to
ṁwat = u ṁwat,nom,
where u is the control input signal and
ṁwat,nom is equal to the parameter
mWat_flow_nominal
. The parameter
mWat_flow_nominal
can be positive or negative. If
ṁwat is positive, then moisture is added to the
air stream, otherwise it is removed.
If the heat port heatPort
is unconnected, then the
enthalpy of the air that flows through the device remains
unchanged, e.g., the humidification is adiabatic. To change the
enthalpy of the air, add heat flow to the connector
heatPort
.
use_T_in
and T
. This
removes the optional specification of temperature through the
parameter T
or the input connector T_in
.
Exposed the heat port of the control volume to allow adding heat,
for example, to use the model as a steam humidifier.prescribedHeatFlowRate=true
. This is for issue
