Linkage control apparatus and method for a two-compressor,

The present invention relates to a control apparatus and method for interlocking dual compressor; PdV01 valve connected to the fresh air compressor, FV03 valve, PdC01 pressure controllers, FV01 flow control valves and FC01; FV03 the other end connected to the second anti-surge valve controller B, the other end of the second anti-surge controller and the pressure controller B connected to valves FV01 FC01 and a flow controller; FV02 recycle gas compressor connected to the valve, a first anti-surge controller A mixing tank and R01; R01 a mixing tank connected to the other end of the pressure controller and valves FV01; FC01 is connected to one end of the valve FV01 flow controller; and the other end connected to an oxygen flow controller FC01 concentration controller; the other end of the oxygen concentration controller of another mixing tank and R01 connecting one end of the output; the present embodiment can effectively control the coordinated operation of the two units, to avoid hurting the compressor off valve unit.
