Abstract:
1. A method for operating a compressor device with an electric drive, comprising: providing a compressor chamber and a cooling chamber which adjoins the compressor chamber, enclosing the compressor chamber by a partition in the form of a tube; and encapsulating the compressor chamber using the partition in relation to a cooling chamber, wherein the cooling chamber is part of a cooling device and comprises a cooling medium which may be transported out of and into the cooling chamber using a cooling circuit line, wherein the cooling medium serves for dissipating heat which develops primarily as a result of a stator section of the electric drive, and wherein during operation of the compressor device, a first pressure of the cooling medium in the cooling chamber is held above a second pressure of a compressor medium in the compressor chamber, wherein a differential pressure device measures a pressure difference between the cooling chamber and the compressor chamber.
