”Environmental Control Library simulates well, and both cold and warm, dry and high moisture simulation cases correspond well with previous results. Thanks for your patient support! We will now start the effort to migrate all the Environmental Control System models to ECL.Ingela Lind, Saab Group
Modelon’s Environmental Control Library is a Modelica library for aircraft environmental control systems analysis and design. The library is designed to study energy consumption and thermal conditions that affect the level of comfort for passengers and crew.
These performance aspects are driven by large variations in ambient conditions such as humidity and temperature. The models provided by Environmental Control Library account for these effects through first principles and fully support bidirectional flow.
The library has been developed internally at Modelon for a number of years together with a European airframer, and starting with version 3.1 it is publicly available. Modelon is now able to offer out of the box a library reinforced through industrial collaboration deployment.
The library provides an efficient and numerically robust framework suitable for large-scale complex systems. Component models include heat exchangers, compressors, turbines, ejectors or jet pumps, water separator, valves, cabin and pipes.
The Environmental Control Library is being used successfully by industry in system performance assessment and control system design.
The models are used to verify how the resulting system robustly delivers air conditioning and auxiliary cooling to all aircraft thermal loads.
