It is known that multiple stage compression with intercooled increases the thermodynamic efficiency of the total compression process bringing the transformation closer to the isothermal limit. This is of particular interest when the reduction of the specific energy of a compressor is paramount. A two stage intercooled rotary vane compressor has been conceived based on an innovative integrated, single stator design. This is the result of further improvements to a comprehensive model for the simulation of a rotary vane compressor system previously developed (1,2). The new modeling features are described and have resulted in turning a model previously used as a prediction tool into a design tool able to modify the compressor geometry following the most sensitive modifications. This has allowed the authors to launch the production of the first 90kW integrated two-stage rotary vane compressor prototype following the theoretical optimization described in this article.
