Abstract (en)

The method involves surrounding a compressor chamber (12) by a separation wall (14) in shape of a tube, which encapsulates the compressor chamber against a cooling chamber (16), which comprises a cooling medium.The cooling medium in a cooling chamber is utilized for discharging of heat, which is caused by a stator part of an electrical drive. The pressure of a cooling medium in the cooling chamber is maintained above the pressure of a compressor medium in the compressor chamber during operation of a compressor device (10). An independent claim is also included for a compressor device operated by the method comprises a unit with a difference pressure measuring device.
