    Abstract
  • Air compressor power consumption was described. Based on analyzing screw air compressor volume flow efficiency under discharge pressure fluctuation conditions, the screw air compressor volume flow formula was obtained, and power consumption mathematic model were established also. Under load/unload operating conditions, to change the unload pressure value in accordance with the space step of 0.01MPa and consider the power consumption affected by current from unload to load, the screw compressor power consumption were simulated by MATLAB. The simulation shows that the existence of the optimal unload pressure value is proved. Power consumption is minimal with using the optimal unload pressure value. Finally, combining the load/unload operating frequency with the optimal unload pressure value, the optimal control method of screw compressor is given.
