Abstract

In the method and apparatus of the present invention, electrical usage is displayed and calculated by multiplying the percentage ofmaximum power already displayed by the operating hours. The result, the kWh, is multiplied by the average unit price for the electricity to determine the cost of electrical energy used by the specific equipment in the particular application in U.S. dollars, or such other unit of monetary measure. This cost shall be displayed together with the savings in kWh and U.S. dollars.

Claims

1. A method for controlling/monitoring a motor control panel used with electrical equipment, said panel being functionally adapted to visually display a percentage of maximum power, to multiply the percentage ofmaximum power by the number of operating hours to determine electrical usage, and to visually display electrical usage, comprising the steps of

inputting the average price of electricity,

multiplying electrical usage by the average price of electricity to determine the cost of electrical energy used, and

visually displaying the cost of electrical energy used.

2. The method of claim 1 wherein the cost of electrical energy used is displayed in U.S. dollars.

3. The method of claim 1 including the step of providing multiple visual displays for comparing savings due to variable frequency drives with competing methods, including inlet guide vanes, discharge damper and throttling valves.

4. A method for controlling/monitoring a motor control panel used with electrical equipment, said panel being functionally adapted to visually display a percentage of maximum power, to multiply the percentage of maximum power by the number of operating hours to determine electrical usage, and to visually display electrical usage, comprising the steps of

inputting the average price of electricity,

multiplying electrical usage by the average price of electricity to determine the cost of electrical energy used,

visually displaying the cost of electrical energy used,

calculating the energy savings, and

visually displaying the energy savings.

5. The method of claim 4 wherein the energy savings is displayed in kilowatt hours.

6. The method of claim 4 wherein the energy savings is displayed in U.S. dollars.

7. The method of claim 4 including the step of providing multiple visual displays for comparing savings due to variable frequency drives with competing methods, including inlet guide vanes, discharge damper and throttling valves.

8. The method of claim 4 wherein maximum motor power is determined and said energy savings calculation step includes the additional steps of

subtracting power used from maximum motor power to determine the savings, and

multiplying the savings by the average cost of the electricity.

9. The method of claim 4 wherein maximum motor power is determined and said energy savings calculation step includes the additional steps of

multiplying maximum motor power by operating hours and by the difference between one and the percentage of maximum motor power to determine the savings, and

multiplying the savings by the average cost of the electricity.

10. A panel for controlling/monitoring a motor used with electrical equipment, said motor control panel including monitoring and programming means, means for multiplying the percentage of maximum power by the number of operating hours to determine electrical usage, and means for visually displaying electrical usage, which comprises

means for inputting the average price of electricity,

means for multiplying electrical usage by the average price of electricity to determine the cost of electrical energy used, and

means for visually displaying the cost of electrical energy used.

11. The panel of claim 10 wherein the cost of electrical energy used is displayed in U.S. dollars.

12. The panel of claim 10 wherein the visual display means includes multiple visual displays for comparing savings due to variable frequency drives with competing methods, including inlet guide vanes, discharge damper and throttling valves.

13. A panel used with electrical equipment for controlling/monitoring one or more motors, said panel including a programmable logic control and being functionally adapted to visually display a percentage of maximum power, means for multiplying the percentage of maximum power by the number of operating hours to determine electrical usage, and means for visually displaying electrical usage, which comprises

means for inputting the average price of electricity,

means for multiplying electrical usage by the average price of electricity to determine the cost of electrical energy used,

means for visually displaying the cost of electrical energy used,

means for calculating the energy savings, and

means for visually displaying the energy savings.

14. The panel of claim 13 wherein the energy savings is displayed in kilowatt hours.

15. The panel of claim 13 wherein the energy savings is displayed in U.S. dollars.

16. The panel of claim 13 wherein the visual display means includes multiple visual displays for comparing savings due to variable frequency drives with competing methods, including inlet guide vanes, discharge damper and throttling valves.
