Compressor characteristics of an oil-free, two phase rotary vane motor for water-steam applications
The development of high temperature heat pumps is often limited by the quality of the excess waste stream. For processes like drying, distillation, frying, pasteurization or evaporators the excess stream is often a combination of different phases (liquid water and saturated steam) which makes the sy...
High temperature industrial heat pumps utilising natural working fluids
There is a large demand for heat typically in the temperature range 100-200⁰C in different industries. This is today often covered by fossil fuel burning or direct use of electricity. Heat pumps has to a lesser extent been utilized due to higher investment cost and limited availability of systems fo...

Turbo-compressors for R-718: Experimental evaluation of a two-stage steam compression cycle
Water (R-718) is a safe and energy-efficient refrigerant. Mechanical vapour recompression (MVR), an open-loop heat pump using R718, can significantly reduce the energy consumption for steam-heated processes like drying, pasteurization, evaporation or distillation. However, the existing compression t...
