Collection of validation models
Information
This package contains validation models for the classes in
Buildings.Fluid.HeatExchangers.DXCoils.
Note that most validation models contain simple input data
which may not be realistic, but for which the correct
output can be obtained through an analytic solution.
The examples plot various outputs, which have been verified against these
solutions. These model outputs are stored as reference data and
used for continuous validation whenever models in the library change.

Validation model for variable speed DX coil under part load condition |
Validation model for variable speed DX coil
Information
This model validates the model
Buildings.Fluid.HeatExchangers.DXCoils.WaterCooled.VariableSpeed.
The difference in results of
TOut and
XOut
at the beginning and end of the simulation is because the mass flow rate is zero.
For zero mass flow rate, EnergyPlus assumes steady state condition,
whereas the Modelica model is a dynamic model and hence the properties at the outlet
are equal to the state variables of the model.
The EnergyPlus results were generated using the example file ZoneVSWSHP_wDOAS.idf
from EnergyPlus 7.1,
with a nominal cooling capacity of 6758 Watts instead of autosizing and an internal gain from
electric equipment as 9400 Watts. This allowed to have a speed ratio of one.
Note that EnergyPlus mass fractions (X
) are in mass of water vapor per mass of dry air,
whereas Modelica uses the total mass as a reference. Hence, the EnergyPlus values
are corrected by dividing them by
1+X
.

Validation model for variable speed DX coil under part load condition
Information
This model validates the model
Buildings.Fluid.HeatExchangers.DXCoils.WaterCooled.VariableSpeed.
The difference in results of
TOut and
XOut
at the beginning and end of the simulation is because the mass flow rate is zero.
For zero mass flow rate, EnergyPlus assumes steady state condition,
whereas the Modelica model is a dynamic model and hence the properties at the outlet
are equal to the state variables of the model.
The EnergyPlus results were generated using the example file ZoneVSWSHP_wDOAS.idf
from EnergyPlus 7.1,
with a nominal cooling capacity of 6758 Watts instead of autosizing and an internal gain from
electric equipment as 6000 Watts.This allowed to have a speed ratio between 0 and 1.
Note that EnergyPlus mass fractions (X
) are in mass of water vapor per mass of dry air,
whereas Modelica uses the total mass as a reference. Hence, the EnergyPlus values
are corrected by dividing them by
1+X
.
