摘要

The present invention relates to a compressor assembly that comprises a compressor (12) cooled by water injection into water-cooling circuit (20) as well as a measuring device (30) located in the water-cooling circuit (20) for determining the conductivity value of the cooling water. The assembly also comprises a water supply (40) for feeding non-desalinated water and desalinated water as well as a control device (70). When a limit value of upper conductivity is exceeded, the control device (70) triggers the inlet of desalinated water from the water supply (40) into the water-cooling circuit (20). When a limit value of lower conductivity is exceeded, non-desalinated water is fed from the water supply (40) into the water-cooling circuit (20). The pH and salt content of the cooling water can thus be controlled so as to reduce corrosion by the cooling water as well as the sedimentation therein.
