As part of the EU-project DryFiciency, SINTEF is developing and testing a novel compressor type together with ROTREX: a so-called turbo compressor. The challenge was to design a gearbox which results in a rotational speed of up to 80.000 rpm for an impeller size of 15 cm and at the same time seal the compressor room from the drive unit. This week the factory assembly tests were finalized successfully and the design is approved for a heat pump application and other steam compression processes.
„The main component in an open loop heat pump system is the compression device“ Michael Bantle (Senior Research Scientist at SINTEF Energy Research, Department of Thermal Energy), recently published a blog article about their work on turbo compressors in the #SINTEFblog.
