Compressor device with cooling, and method for operating a compressor device

A compressor system comprising

• a compressor for compressing a gas for generating a compressed gas, the compressor including a compressor stage, and
• a cooling system, the cooling system including
• an oil cooler for cooling oil heated by the compressor,
• a compressed gas cooler for cooling the gas that is completely or partially compressed to form the compressed gas, and
• a housing cooler for cooling a housing or part of the housing of the compressor, wherein
• the oil cooler, the compressed gas cooler and the housing cooler are each arranged to be cooled by a coolant flow comprising a liquid coolant, wherein
• a housing cooler control comprising a valve or a pump for individually controlling the coolant flow through the housing cooler is provided for the housing cooler, and
• the compressor system has a cooling control comprising a computer configured to actuate the housing cooler control, wherein the computer controls the housing cooler to control the coolant flow independently of the coolant flow through the oil cooler, wherein
• the compressor further includes a rotor for compressing the compressed gas and a compressor gap having a variable gap thickness formed between the housing and the rotor or between two rotors, and wherein
• the cooling control is arranged to actuate the housing cooler control to ensure the gap thickness remains within a predeterminable range, and/or that the gap thickness follows a predeterminable desired gap thickness.
