Sammendrag
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 system
integration of a heat pump challenging.
Rotary vane motors can handle two phase flows, which enables especially steam application to
compress the excess stream directly to higher pressure and temperature levels while the liquid water
phase is used to cool the compressor simultaneously. Experimental results from a prototype oil-­free
rotary vane machine is presented, and its performance indicators are presented and discussed in
detail. Two approaches to determine the isentropic efficiency is presented, due to unconventional
two-­phase mechanisms. The vane compressor is evaluated with respect to industrial
implementation.
