Transient thermal management of vapor cycles to simulate aircraft electrical environment control systems.

Summary

A Modelica library has been developed to simulate thermal management architectures of Electrical Environmental Control Systems (E-ECS) in new generation aircrafts. The modeling of these architectures requires significant efforts to overcome the non-negligible number of numerical difficulties related to the steady-state and dynamic resolution of both particular components and subsystems. The library main goal is to conduct accurate and robust simulations with optimized computational time based on an appropriate trade-off between component model simplicity and ability to represent its behavior accurately. The work presented herein is focused on the resolution of the Vapor Compression System (VCS) and its integration within the aforementioned E-ECS architectures. The VCS has been modeled together with other relevant subsystems in order to assess the library numerical capacities and to study the influence of some relevant parameters such as the environment temperature or the VCS compressor working frequency.
