Information

Note: The packages whose name ends with Beta are still being validated.

• Added the package Buildings.ThermalZones.Detailed to compute heat transfer in rooms and through the building envelope. Multiple instances of these models can be connected to create a multi-zone building model.
• Added the package Buildings.HeatTransfer.Windows to compute heat transfer (solar radiation, infrared radiation, convection and conduction) through glazing systems.
• In package Buildings.Fluid.Chillers, added the chiller models Buildings.Fluid.Chillers.ElectricReformulatedEIR and Buildings.Fluid.Cphillers.ElectricEIR, and added the package Buildings.Fluid.Chillers.Data that contains data sets of chiller performance data.
• Added package Buildings.BoundaryConditions with models to compute boundary conditions, such as solar irradiation and sky temperature.
• Added package Buildings.Utilities.IO.WeatherData with models to read weather data in the TMY3 format.
• Revised the package Buildings.Fluid.Sensors.
• Revised the package Buildings.Fluid.HeatExchangers.CoolingTowers.
• In Buildings.Fluid.Interfaces.StaticFourPortHeatMassExchanger and Buildings.Fluid.Interfaces.StaticFourPortHeatMassExchanger, fixed bug in energy and moisture balance that affected results if a component adds or removes moisture to the air stream. In the old implementation, the enthalpy and species outflow at port_b was multiplied with the mass flow rate at port_a. The old implementation led to small errors that were proportional to the amount of moisture change. For example, if the moisture added by the component was 0.005 kg/kg, then the error was 0.5%. Also, the results for forward flow and reverse flow differed by this amount. With the new implementation, the energy and moisture balance is exact.
• In Buildings.Fluid.Interfaces.ConservationEquation and in Buildings.Media.Interfaces.PartialSimpleMedium, set nominal attribute for medium to provide consistent normalization. Without this change, Dymola 7.4 uses different values for the nominal attribute based on the value of Advanced.OutputModelicaCodeWithJacobians=true/false; in the model Buildings.Examples.HydronicHeating.
• Fixed bug in energy balance of Buildings.Fluid.Chillers.Carnot.
• Fixed bug in efficiency curves in package Buildings.Fluid.Movers.BaseClasses.Characteristics.
