Abstract
With a simulation apparatus for a system including a motor-driven compressor, a compressor that does not suffer from a driving torque shortage and surging, but can operate at low costs, can be provided. A simulation apparatus for a motor-driven compressor system includes a simulation section in which a driving motor, a compressor driven by the driving motor, a suction throttle valve controlling the inlet flow rate of the compressor, and an anti-surge valve interposed between pipes for returning a part of gas discharged from the compressor to the inlet side of the compressor are translated into unit models and stored. The simulation apparatus further includes an input section through which designed specification data of the compressor is input, a data setting section storing the designed specification data, and a display section displaying unsteady-state Q-H characteristics and required driving torque obtained through simulation by the simulation section.
