Environmental Control Library 3.16 is part of Modelon's 2024.1 release.

New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.

New features

  • Mass estimation of components within MassEstimate.
  • New experiment demonstrating the use of more electric air cycle and mass estimate MoreElectricAirCycle. Including a workflow on how to go from an OnDesign (sizing) model to OffDesign (performance) model.
  • New compact heat exchanger available with build-in sizing functionality StaticSizing
  • Models of electric AntiIce protection for both wings and nacelles


  • Compressors.Examples.CentrifugalAECS and Turbines.Examples.CentrifugalAECS has more parameterization option and improved robustness.
  • Demonstrated the use of MassEstimate in PipeAndValves.
  • Added more turbomachinery in the model TurbomachineSizing.
