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.
