<P>PROBLEM TO BE SOLVED: To display a power consumption saving effect by an energy saving operation on a screen in real-time in order to easily know and recognize the calculated power consumption saving effect in the process of the energy saving operation. <P>SOLUTION: On a screen of an image display unit of a data processing apparatus, a target load equipment operation amount coordinate axis and a target load equipment power consumption coordinate axis are set. A first curve, which specifies a relation of load equipment power consumption to the load equipment operation amount before inverter introduction, and a second curve, which specifies a relation of power consumption to the operation amount when the introduced operating inverter controls the number of revolutions, are displayed on the screen together with measured values of real-time power consumption during the inverter operation. A first screen is so formed as to display the saved power consumption during the inverter operation as a difference between the power consumption before inverter introduction on the first curve and the measured value of real-time power consumption during the inverter operation. <P>COPYRIGHT: (C)2010,JPO&INPIT |
