ORF 3 Interview Prof. Rieberer on June 6th, 2019
The eco2jet project partners Virtual Vehicle, Liebherr and TU Graz presented a peer-reviewed paper named "Eco-friendly, energy- and cost-efficient A/C system with heat pump functionality using R744 for rail applications" at the 8th IIR Conference. Schrank, Rauch, Presetschnik, Rieberer: Eco-friendly, energy- and cost-efficient A/C system with heat pump functionality using R744 for rail applications. 8th IIR Conference: Ammoia [...]
The eco2jet consortia represented by Thomas Hartmann (ÖBB) took part at Rail Operator Meeting in Minden, Germany (invited by DB).
Finalization of Masterthesis Lucas Winder, MSC „Construction and Commissioning of R744 - refrigeration system with heat pump function for railway applications“ This master thesis deals with the construction and commissioning of a refrigeration system test bench for the conditioning of the passenger cabin of a train. The investigated system is supposed to take over the [...]
During this meeting the first project results were presented. One main focus was an innovative heat register (see figure in front of the project team) build-up with thermal-heating foils, which delivers a major part for the increase of energy efficiency within the R744-HVAC system.
The eco2jet consortium met in Graz at Virtual Vehicle to finalize the last adaptions concerning the TRL-6 components including heat exchanger, piping and heat register. Furthermore, first development results on the research focus of the project were presented: heat exchanger de-icing, surface heating for the waggon entry and intelligent control & predictive maintenance activities. The [...]
All the project partners met in the premises of Rupert Fertinger. They aimed to finalize the relevant aspects for the production of the R744 heat exchanger including the de-icing functionality, the heat register and the piping. All relevant decisions were made considering the integration of the advanced R744 heat exchanger and its components into the [...]
The project consortium finished successfully the project phase by finalizing the requirements specifications and submitting first preliminary results of development steps. Please, find the download link for our first Interim Report in German and English: 20180330_eco2jet_1st_Interim_report
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 [...]
