In February 2025, Michael Kremer enhanced the RWTH-EBC/AixLib repository by refactoring the ModularAirHandlingUnit simulation architecture to improve model fidelity and validation efficiency. He introduced a PartialComponent base class in Modelica, standardized interfaces, and updated control logic for heating, cooling, and dehumidification. Michael developed new validation and plotting scripts, streamlined simulation tolerances, and optimized airflow component models, focusing on numeric precision and maintainability. His work included targeted code cleanup and removal of obsolete tests, resulting in faster CI validation and more reliable HVAC system simulations. These updates leveraged Modelica scripting, object-oriented design, and simulation best practices for robust, testable results.
