The application relates to a method for controlling the water supply of a water-injected gas compressor which has a cooling water circuit into which is injected, as fresh water, demineralized water and non-demineralized water. The method according to the application comprises the following steps: determination of the electrical conductivity of the non- demineralized water; determination of a proportion of the demineralized water that must be added to the non-demineralized water, to provide a resulting mixture with a desired conductivity; addition of the specified proportion of demineralized water to the non-demineralized water and supplying the resulting mixture as the fresh water for the cooling water circuit; supply of the fresh water to the cooling water circuit in a desired amount. Further, the application relates to a Water-injected gas compressor comprising a compression stage, a cooling water circuit, and a water mixing unit. |
