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.
