A workshop on the topic ejector for refrigeration circuits took place at the Institute for Thermal Engineering at TU Graz. The workshop focussed on a critical question of the project whether to use an ejector within the R744 HVAC system or not.

Starting with a basic technology analysis by Liebherr and the Virtual Vehicle, the workshop members discussed several aspects regarding energy efficiency, cost aspects, life cycle aspects and producibility.

Finally, the team concluded to proceed with a deeper analysis of railway specific aspects and requirements to get a clear answer to the main question of the workshop.
