  • Compressor system and control method of the same
    Patent number: 11118593
    Abstract: A compressor system includes an inlet in which fluid flows, an inlet temperature measuring part configured to measure an inlet temperature (T_in) of the fluid at the inlet, an inlet guide vane (IGV) configured to change opening degree (IGV_position) to control a flow rate of the fluid through the inlet, a compressor to compress the fluid passing through the inlet guide vane, a motor connected to the compressor to drive the compressor, and configured to change rotating speed, a discharge pressure measuring part to measure a discharge pressure (P_disch) of the fluid passed the compressor, an outlet to discharge the compressed fluid, and a check valve installed at the outlet to prevent backflow of the fluid.
