Refactored the models and data recoreds for issue 2668. |
| Buildings.Fluid.Movers.FlowControlled_m_flow | Added assertion to avoid using the model with a head that is
significantly higher than the head specified by its performance curve. This is for IBPSA, #1659. |
| Buildings.Fluid.SolarCollectors | |
| Buildings.Fluid.SolarCollectors.Controls.CollectorPump | Corrected implementation to make comparison based on total irradiation on tilted surface
rather than the direct normal irradiation.
This required adding parameters for the azimuth, tilt and ground reflectance. Added hysteresis to the controller, and changed output signal to be boolean-valued on/off rather than a continuous signal. Moved the old implementation to Buildings.Obsolete.Fluid.SolarCollectors.Controls.This is for #3074. |
| Buildings.ThermalZones.EnergyPlus_9_6_0.Examples.SingleFamilyHouse | |
| Buildings.ThermalZones.EnergyPlus_9_6_0.Examples.SingleFamilyHouse.HeatPumpRadiantHeatingGroundHeatTransfer | Replaced ideal heater with a geothermal heat pump. |
| Buildings.Obsolete | |
| Buildings.Obsolete.DistrictHeatingCooling | Removed package which is no longer supported. |
| Buildings.Utilities.Plotters | |
| Buildings.Utilities.Plotters.Examples.BaseClasses.CoolingCoilValve | Because of the removal of Logical.And3 based on ASHRAE 231P,
replaced it with a stack of two Logical.And blocks.This is for #2465. |
The following critical errors have been fixed (i.e., errors that can lead to wrong simulation results):
| Buildings.Controls.OBC | |
| Buildings.Controls.OBC.ASHRAE.G36_PR1.Generic.SetPoints.OperationMode | Corrected input for enabling freeze protection setback mode. This is for issue 3084. |
| Buildings.Controls.OBC.CDL | |
| Buildings.Controls.OBC.CDL.Reals.Sources.CalendarTime | Refactored implementation to avoid wrong day number due to rounding errors
that caused simultaneous events to not be triggered at the same time. This is for issue 3199. |
| Buildings.Electrical.DC | |
| Buildings.Electrical.DC.Storage.BaseClasses.Charge | Corrected calculation of power taken from the battery when it is discharged. This is for issue 3095. |
| Buildings.Examples | |
| Buildings.Examples.HydronicHeating.TwoRoomsWithStorage | Corrected outdoor temperature in instance TOutSwi at which system switches on and off.This is for issue 3059. |
| Buildings.Experimental | |
| Buildings.DHC.ETS.Combined.HeatPumpHeatExchanger | Assigned dp_nominal to pum1HexChi.Corrected calculation of heat pump evaporator mass flow control. This is for issue 3379. |
| Buildings.DHC.ETS.Combined.Subsystems.HeatPump | Assigned dp_nominal to condenser pump. This is for issue 3379. |
| Buildings.DHC.ETS.Cooling.Indirect | Fixed building supply temperature controller parameter reverseActing
by changing from true to false.This is for issue 3299. |
| Buildings.DHC.ETS.Cooling.Direct | Removed assignment of check valve allowFlowReversal=false.This is for #3389. |
| Buildings.DHC.Loads.BaseClasses.Examples.BaseClasses.BuildingTimeSeries | Applied facMul to domestic hot water load.This is for issue 3379. |
| Buildings.Fluid.HeatExchangers | |
| Buildings.Fluid.HeatExchangers.BaseClasses.PartialEffectivenessNTU | Corrected wrong temperature in assignment of sta2_default.
For Buildings.Media.Air and Buildings.Media.Water
this error does not affect the results.This is for Buildings, issue 3151 |
| Buildings.Fluid.DXSystems.AirCooled.MultiStage Buildings.Fluid.DXSystems.AirCooled.SingleStage Buildings.Fluid.DXSystems.AirCooled.VariableSpeed Buildings.Fluid.DXSystems.WaterCooled.MultiStage Buildings.Fluid.DXSystems.WaterCooled.SingleStage Buildings.Fluid.DXSystems.WaterCooled.VariableSpeed Buildings.Fluid.DXSystems.Cooling.BaseClasses.CapacityWaterCooled Buildings.Fluid.DXSystems.BaseClasses.PartialCoolingCapacity |
Corrected performance calculation as a function of mass flow rates. This is for #3146. |
| Buildings.Fluid.HeatExchangers.WetCoilCounterFlow Buildings.Fluid.HeatExchangers.WetCoilDiscretized |
Reverted the correction on latent heat from component. This is for #3065. |
| Buildings.Fluid.HeatExchangers.Validation.WetCoilCounterFlowLowWaterFlowRate |
Modify air source boundary condition so air enters coil at 99.5% relative humidity. This is for #3065. |
| Buildings.Utilities.Time | |
| Buildings.Utilities.Time.CalendarTime | Refactored implementation to avoid wrong day number due to rounding errors
that caused simultaneous events to not be triggered at the same time. This is for issue 3199. |
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.Fluid.HeatExchangers | |
| Buildings.Fluid.DXSystems.Cooling.BaseClasses.Evaporation | Corrected assertion for the condition dX_nominal<0 and the documentation.This is for issue 3322. |
