Information

Version 7.0.2 is a bug fix release. The library has been tested with Dymola 2022, JModelica (revision 14023), OpenModelica 1.19.0-dev (449+g4f16e6af22) and OPTIMICA (revision OCT-stable-r19089_JM-r14295).

The following changes have been done:

The following new components have been added to existing libraries:

Buildings.Fluid.Chillers
Buildings.Fluid.Chillers.Data.ElectricEIR.ElectricEIRChiller_York_YCAL0033EE_101kW_3_1COP_AirCooled Data for air cooled chiller.
This is for Buildings, issue #2770.

The following existing components have been improved in a backward compatible way:

Buildings.Controls.Continuous
Buildings.Controls.Continuous.SignalRanker Changed implementation to use sort function from Modelica Standard Library, and updated its example to avoid simultaneous state and time events.
This is for IBPSA, #1534.
Buildings.Examples.ChillerPlant
Buildings.Examples.ChillerPlant.BaseClasses.DataCenter Set nominalValuesDefaultPressureCurve=true to avoid warnings.
This is for Buildings, issue #2761.
Changed initialization from steady state initial to fixed initial for some components.
This is for Buildings, issue #2798.
Buildings.ThermalZones.ReducedOrder
Buildings.ThermalZones.ReducedOrder.Validation.VDI6007.BaseClasses.VerifyDifferenceThreePeriods Improved model to guard against approximation errors of event handling. With this change, the models in Buildings.ThermalZones.ReducedOrder.Validation.VDI6007 all simulate with OpenModelica.
This is for Buildings, issue #2713.
Buildings.Utilities.Math
Buildings.Utilities.Math.Functions.BaseClasses.der_spliceFunction Reimplemented function to avoid a potential overflow caused by the cosh function.
This is for IBPSA #1531.

The following critical errors have been fixed (i.e., errors that can lead to wrong simulation results):

Buildings.Fluid.Chillers
Buildings.Fluid.Chillers.BaseClasses.PartialElectric Corrected calculation of entering condenser temperature when using a moist air media model. This is important for modeling air-cooled chillers using the model Buildings.Fluid.Chillers.ElectricEIR.
This is for Buildings, issue #2770.
Buildings.Occupants
Buildings.Occupants.Office.Occupancy.Wang2005Occupancy Reformulated model so it works also if the simulation does not start at 0.
To improve efficiency, this reformulation also changes the event triggering function so that it leads to time events rather than state events.
This is for Buildings, #2590.

The following uncritical errors have been fixed (i.e., errors that do not lead to wrong simulation results, e.g., units are wrong or errors in documentation):

Buildings.Airflow
Buildings.Airflow.Multizone.DoorOperable Removed duplicate declaration of VABp_flow.
This is for Buildings, issue #1496.
Buildings.Electrical
Buildings.Electrical.AC.OnePhase.Storage.Battery
Buildings.Electrical.DC.Storage.BaseClasses.Charge
Buildings.Electrical.DC.Storage.Battery
Corrected unit string.
This is for Buildings, issue #2798.
Buildings.Applications.DataCenters
Buildings.Applications.DataCenters.ChillerCooled.Examples.IntegratedPrimaryLoadSideEconomizer
Buildings.Applications.DataCenters.ChillerCooled.Examples.IntegratedPrimarySecondaryEconomizer
Buildings.Applications.DataCenters.ChillerCooled.Examples.NonIntegratedPrimarySecondaryEconomizer
Corrected weather data bus connection which was structurally incorrect and did not parse in OpenModelica.
This is for Buildings, issue 2706.
Buildings.ThermalZones.Detailed
Buildings.ThermalZones.Detailed.BaseClasses.RadiationTemperature Corrected annotation.
This is for Buildings, issue #2550.
Buildings.ThermalZones.Detailed.Constructions.Examples.ExteriorWallTwoWindows
Buildings.ThermalZones.Detailed.Constructions.Examples.ExteriorWallWithWindow
Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.Electrical
Buildings.ThermalZones.Detailed.Validation.BESTEST.Cases6xx.Case600FF
Added missing parameter declaration.
This is for Buildings, issue #2556.
