AixLib v1.3.0

Release Notes

The following highlights show some of our achievements with reaching v1.3.0:

Modelica Standard library

• Update to MSL4.0

IBPSA

• Merge of current IBPSA modelica base repository
• IBPSA models are now marked by an icon

Improvements in CI

• New reference results for some models (e.g. pump examples)
• Integration of google charts for the comparision of reference results

Changes in ThermalZone

• ROM:
  • Integration of post processing blocks with some interesting outpus (e.g. sum of energy for heating) into AixLib.ThermalZones.ReducedOrder.Multizone.BaseClasses
• HOM:
  • New partial model to increase usability / modelling speed for users of the model: AixLib.ThermalZones.HighOrder.Rooms.BaseClasses.PartialRoomFourWalls
  • Replacing air load model with air volume to provide possibility to consider CO2 and humidity
  • Move AixLib.ThermalZones.HighOrder.Rooms.MFD.OneAppartment to obsolete

Changes for Thermal energy storage

• Substituting the model AixLib.Fluid.Storage.Storage by AixLib.Fluid.Storage.BufferStorage in most of the examples as it is more detailed and hence realistic

New pump model

• AixLib.Fluid.Movers.DpControlledMovers
  • This model represents a pump or fan which includes already a controller.
  • This enables the user to quickly select between the two common control modes constant pressure (dpConst) and variable pressure (dpVar).

New control models

• AixLib.Systems.HydraulicModules.Controller.CalcHydraulicPower:
  • Calculates the power of hydraulic modules and returns the power as real.
• AixLib.Systems.HydraulicModules.Controller.CtrThrottleQFlow:
  • Simple controller for Throttle and ThrottlePump circuit that is based on a PID controller.

New TABS model

• AixLib.Systems.TABS:
  • This module is a thermally activated building system (TABS) with a closed hydraunic system that is connected to the concrete and supplied by two throttle circuits via heat exchangers.

New AHU model

• AixLib.GenericAU
  • The GenericAHU is an air-handling unit model with detailed hydraulic system of the preheater, heater and cooler. The ahu includes a heat exchanger for heat recovery and a humidifier for the supply air. The humidifier can be insert steam or water that evaporates completely (adiabatic). Further, the ahu includes an adiabatic humidifier in the return air channel in order to cool the return air and use the heat recovery heat exchanger to cool the supply air. The preheater, steam humdifier and adiabatic humidifier are conditional and can be deactivated.
  • Further related models:
    • AixLib.Fluid.Movers.Data.Fans.GenericFan
    • AixLib.Systems.ModularAHU.BaseClass.GenericAHUBus
    • AixLib.Systems.ModularAHU.Controller.CtrAHUBasic
    • AixLib.Systems.ModularAHU.Examples.EONERC_AHU2
    • AixLib.Systems.ModularAHU.Examples.GenericAHU

• Added weather data for Aachen
