The International Conference on Screw Machines 2022 features presentations on numerous aspects of design, operation, and investigation of screw machines. Join the ICSM 2022 and learn about
- multiphase flow
- simulation & experiment
- vacuum technology
- contact- & flow-related loss mechanisms.
Connect with researchers, manufacturers, service providers, and users from the global screw machine community. We are very much looking forward to welcoming you in Dortmund this September.
The programme includes
- keynote sessions
- paper presentations
- science update sessions with plenty of room for discussions
- lab tours
- a conference dinner
- and, of course, many chances to get in touch with experts on screw machines.

Hydrogen as multivalent energy carrier - also for mobility?
Many countries around the world are turning towards climate friendly energy usage. One of the main options appreciated is seen in electricity won from renewables and then used in a direct way for stationary and mobile applications. Taking into account that there’s still a big lack for electric energy storage, hydrogen as an energy carrier more and more plays an important role. Producible via many different ways from almost any primary energy with different sizes of carbon footprints, it can be stored in large quantities, transported by pipelines, road or sea and can be used in a lot of applications. A selection of pathways for hydrogen as future energy carrier for mobility is presented and discussed.

Improving vapor compression system efficiency through advanced vapor compression technologies
The phase-out of ozone depleting and climate changing refrigerants as well as recent advances in compressor and other vapor compression component technologies, such as novel capacity control methods, use of smart sensors, materials and manufacturing practices, has rapidly increased the research efforts related to vapor compression systems for the HVAC&R industry. This presentation provides an overview of several research efforts related to novel compression concepts and unique cycle integration measures for refrigeration, air-conditioning and heat pumping applications with the goal to reduce irreversibilities and move system performance closer to Carnot efficiency. These research efforts include refrigerant injected compression with economization, near-isothermal compression with cylinder cooling and internal regeneration and rotor-cooled compression in twin screw compressors. The latest state-of-the-art of each of these research efforts will be introduced and discussed.
