Methods for regulating the performance of screw compressors
Annotation
The relatively simple and reliable design, the high degree of automation, and the use of cost-effective performance control methods minimize the specific energy consumption and make the operation of screw compressors commercially attractive. The goal of all screw compressor performance control systems is to ensure optimal, in terms of minimum energy consumption, compressor operation while maintaining a relatively constant final compression pressure, regardless of the required flow rate of the working medium in the network. The paper considers a complete classification of methods for regulating the performance of screw compressors and gives a comparative assessment of the possibility of their application for a screw single-rotor compressor.
