Method for controlling a kinetic compressor

摘要

In a method for controlling the functioning of a compressor, a so-called mass flow is selected as starting point for the control function <IMAGE> According to the invention a control algorithm is formed linking the dimensionless mass flow, the shaft torque and the rotational speed of the electrical machine. The dimensionless mass flow Qdim is obtained as a required value or within required limits by obtaining the torque T of the electrical machine that drives the compressor and the rotational speed of the compressor shaft essentially within the value that is determined by the control algorithm. <IMAGE>
