ABSTRACT:
A method of controlling a fluid compression system having at least one compressor for compressing a fluid medium includes defining the permissible minimum and maximum values of the user line pressure at the point of demand. The user line pressure is continuously monitored using a pressure sensor, and the working pressure of the compressor is monitored. The pressure difference between the working pressure of the compressor and the user line pressure at the point of demand is monitored. The pressure rate-of-change of the fluid medium delivered to the point of demand is monitored, and at least one of the compressors is controlled by a control unit on the basis of at least one of the monitored parameters defined in the foregoing steps of the method. A control system for controlling the operation of at least one compressor uses a plurality of sensors for sensing the status of the flowing medium.
