ABSTRACT:
In a method of operating a compressor, a gaseous medium is compressed in a first compressor stage. The partially compressed medium is sent from the first compressor stage into an intermediate cooler where it is cooled before being directed into the second compressor stage where it is compressed further. A liquid medium is sprayed into the gaseous medium in the intermediate cooler so that a two-phase mixture with a liquid phase and a gaseous phase is formed in the intermediate cooler. The liquid phase is separated again before adding it to the second compressor stage.
