System simulation for optimal air conditioning and oxygen distribution systems design
Maximizing passenger comfort while minimizing energy consumption, LMS Imagine.Lab helps engineers design optimal air conditioning and oxygen distribution systems, providing a comfortable and safe environment in terms of cabin pressure, temperature, air flow and humidity levels for crew and passengers alike.
During the concept phase, experts are able to simulate the entire system on a single platform and optimize the system architecture while multi-level analysis allows them to dig into details like thermo-dynamic gas mixture and humidity description. Further along during specification, engineers can design detailed components and validate their models, reducing the design and development lifecycle and related costs. And finally during the integration phase, the solution can be used to validate system integration and performance.
LMS Imagine.Lab offers both predefined and customizable component libraries suitable for gas mixtures and humidity representation to accurately predict the air composition evolution and model the complete pneumatic circuits and various liquid and gas distribution systems.
LMS Imagine.Lab AMESim can easily interface with most CFD software to integrate detailed 3D geometry to improve the overall system simulation and define boundary conditions for the CFD software.
The complete solution helps engineers design optimal air conditioning and oxygen distribution systems, providing a comfortable and safe environment in terms of cabin pressure, temperature, air flow and humidity levels for crew and passengers alike.
