Model for a heat and moisture exchanger with constant effectiveness.
This model transfers heat and moisture in the amount of
QSen = epsS * Q_max, m = epsL * mWat_max,
where epsS
and epsL
are constant effectiveness
for the sensible and latent heat transfer,
Q_max
is the maximum sensible heat that can be transferred and
mWat_max
is the maximum moisture that can be transferred.
For a sensible heat exchanger, use Buildings.Fluid.HeatExchangers.ConstantEffectiveness instead of this model.
This model can only be used with medium models that define the integer constant
Water
which needs to be equal to the index of the water mass fraction
in the species vector.
final prescribedHeatFlowRate1=true
and
final prescribedHeatFlowRate2=true
.Q1_flow
did not include latent heat flow rate.Medium1.Water
by introducing
the parameter i1_w
, and used a similar construct for
Medium2
.
This avoids an error during model check as these constants are not known
in the partial medium model.
mWat_flow
in the base class.
