It is a figure shown by.

  In FIG. 1, an energy consumption status display device 100 for an energy consumption device or an inverter control motor includes a central processing unit, that is, a processing unit (CPU) 1 and a screen display or an electronic panel display (hereinafter referred to as drawing display). Screen display device 2 for receiving information, receiving device 3 for inputting information (data), output device 4 for outputting generated information to the outside, power supply circuit 5 and database 6.

In FIG. 2, numerals 11 to 23 indicate execution means.

  For the energy consumption system 101, an energy consumption power device or an inverter control motor is used.

  In the energy consumption system 101, the entire energy consumption system or a part of them may be replaced with a new type of energy consumption system in order to reduce energy consumption (hereinafter sometimes referred to as energy saving). is there. Here, the energy consumption device 102 used in the past is replaced with the energy consumption device 102 of the old type, and the energy consumption system 103 replaced and replaced is replaced with the energy consumption device 103 of the new type. It shall be called.

  When introducing a new type of energy consumption device 103, for example, a motor by inverter control instead of the conventional motor control other than the inverter control, the old type energy consumption device 102 is operated before the introduction. In this state, the energy consumption situation of the old type, that is, the new energy generation amount relative to the energy supply amount is measured in the form of the electric output amount or the heat output amount, the energy consumption information is analyzed, and the energy consumption is stored in the database 6A of the database 6 It is stored as data (map) (11). As a result, the energy generation amount with respect to the required energy output amount in the old type energy consuming power device 102 is held as data every moment or every certain period. In this way, when data is not held, as shown in Patent Document 3, commercial energy may be adopted as an energy input amount with respect to an energy output amount by an old type energy consuming device.

Further, the adder 23 adds the reduced CO ₂ amount (17) and the reduced CO ₂ amount converted value (21) on the amount to calculate the amount equivalent CO ₂ reduction amount.

  The energy saving effect amount (13) is converted into an amount by using the energy saving effect amount unit data (16) of the database 6D, and the energy saving amount calculation means (not shown) calculates the energy saving amount.

Similarly, the reduced CO ₂ amount (17) is converted into an amount using the CO ₂ reduction amount unit price data (15) of the database 6C, and the reduced CO ₂ effect amount calculation means (not shown) is reduced CO ₂ effect amount. Is calculated.

Similarly, the equivalent energy saving effect amount calculation means calculates the equivalent energy saving effect amount corresponding to the amount equivalent energy saving effect amount, and the equivalent reduction CO ₂ effect amount calculation means corresponds to the amount equivalent CO ₂ reduction amount. ₂ Calculate the effect amount. Here, the amount and the economy are synonymous.

  Any data calculated in this way is stored in the database 6. Further, the data calculated in this way is transmitted to the screen display device 2 by the transmission means 39.

May be an image panel. Accordingly, the screen display device 2 can be arranged in the factory or in each office.

  Each data stored in the database 6 is transmitted to the screen display device 2 and used for screen display, but may be output from the output device 4 so as to be used for other usage forms.

On the screen of the screen display device 2, the above-mentioned energy saving effect amount 31 calculated by each calculation means simultaneously or separately, the energy saving saving amount 32 in parallel with this, the reduced CO ₂ amount, and the reduced CO ₂ effect amount in parallel with this 34, an amount equivalent energy saving effect amount 35, an equivalent energy saving effect amount 36 in parallel therewith, an amount equivalent CO ₂ reduction amount, and an equivalent reduction CO ₂ effect amount 38 in parallel therewith are displayed. Some of these data may be displayed by the selection means.

FIG. 8 shows operational data for each block shown in FIG. 2 based on these data. In FIG. 8, it is assumed that the CO ₂ reduction unit price, that is, the emission purchase price is 3000 yen / tCO _2, and the energy saving effect unit price, that is, the power purchase unit price is 12 yen / kWh. The description of FIG. 8 is used here.

  In this embodiment, when a plurality of energy consumption devices are used in the energy consumption system 101, an operation history collection unit that collects operation histories of each of the plurality of energy consumption devices is provided. A tag (IC tag, μ chip) in which an operation history for each of the energy consumption devices is recorded, a data receiving unit for obtaining an operation history for each energy consumption device from these tags, and an acquired operation history A reading device including a data transmission unit for transmitting to the arithmetic device 1; Data from the reading device is transmitted to the receiving device 3 (FIG. 1).

6 and 7 show a flowchart of the present embodiment. FIG. 6 shows a flow in the case where there is a plurality of CO ₂ emission forms and there is versatility to use a plurality of calculation programs corresponding to these. FIG. 7 shows a specific CO ₂ emission form. The flow for simple and quick calculation using this specific calculation program is shown below.

  In FIG. 6, a database is constructed. The contents of the database are described above.

If one of the CO ₂ emission mode that depends on the power company from a plurality of CO ₂ emission forms are designated (S2), select a calculation program corresponding to the CO ₂ emission form is made (S3).

It is determined whether energy saving amount information is required or CO ₂ reduction information is required (S4). If energy saving amount information is required, an energy saving amount conversion value on the amount is calculated from the reduced CO ₂ amount. (S5) Then, the energy saving amount and the energy saving amount converted value are added to calculate the amount corresponding to the amount of energy saving effect (S6).

Alternatively, if the CO ₂ reduction information is a necessity, the reduced CO ₂ amounts in the amount from the energy saving effect amount is calculated (S7), and then reducing CO ₂ amount reduced value and reduce CO ₂ amount is additional amount The equivalent CO ₂ reduction amount is calculated (S8).

  When both pieces of information are required, the data described above are calculated in series. Further, the amount of money for these data can also be calculated.

  The data generated in this way is displayed on the screen (S9) and output for other purposes (S10). The contents of the screen display are as described above.

  In the example of FIG. 7, only steps S2 and S3 are changed to steps S2A and S3A, and the other steps are the same as shown in FIG.

When the database is constructed (S1), using the stored specific calculation program (S2A), the reduction CO ₂ amount calculation is immediately performed from the energy saving effect amount (S3A). The description about FIG. 6 is used about another step.

  According to the applicants of the present application and the like, many achievements have been made by the alternative replacement to the inverter control motor. According to this experience, it is possible to generate new information as shown below when substituting for an inverter control motor. By utilizing this information, it is expected to further promote substituting for an inverter control motor. I found out.

  FIG. 9 shows calculation cases of the energy saving effect amount as case 1, case 2 and case 3. Case 1 shows the assumed energy saving effect calculation, Case 2 shows the selected energy saving effect calculation, and Case 3 shows the actual measured energy saving effect calculation. FIG. 9 shows data stored as an energy map (11) in the database 6A for these cases and the consumption energy amount (12) calculated by the consumption energy amount calculation means 12. The consumption energy amount is calculated from the stage 1 and the stage 2. It shows the calculation at the stage over time. In case 1 and case 2, the information generation state before the inverter control motor is installed is shown. In case 3 of stage 1, the inverter control motor as described above with reference to FIG. 2 is installed. Indicates the information generation status. In stage 2, the information generation status when the inverter control motor is installed in all cases is shown. The case 3 will be described.

  In case 3, the data stored as the energy map (11) in the database 6A indicates a case where a value measured before the inverter control motor is installed, that is, a value measured in advance is determined as a data value on the map. That is, conventional electric quantity data indicating the effective operation amount with respect to the measured electric usage amount of a motor (conventional motor) other than the inverter control motor actually installed as an actual machine is stored in the form of a map. In stage 2, the value measured for the inverter control motor at the time of energy saving, that is, inverter electric quantity data indicating the effective operation amount with respect to the actually measured electric usage is stored in a map format. In stage 3, this state is continued. The situation shown in Case 3 is known.

  In case 2, the data stored as the energy map (11) in the database 6A is the same as in case 3. In case 2, the inverter control motor is not yet installed. Therefore, data must be generated assuming that an inverter control motor is installed. For this purpose, the database 6A stores inverter electric quantity usage data of many various capacities obtained from experience, and the user determines an appropriate capacity from the inverter electric quantity usage data, thereby obtaining one electric usage quantity. Is selected and input to the arithmetic unit 1.

  As a result, in stage 1 of case 2, a past similar case is selected by referring to the capacity, and an effective operation amount for the past electricity usage selected as a data value on the map is determined and set. Thereby, even before the inverter control motor is installed, a rough energy saving effect amount is calculated as if the inverter control motor was installed. When the case 2 and the stage 2 are reached, the energy saving effect amount is accurately calculated equivalent to the case 3, the energy saving effect amount obtained in the stage 1 is calculated, and the energy saving effect amount obtained in the stage 1 is corrected. In this case, although it is a rough energy saving effect, there is an advantage that information can be provided in advance.

  Case 1 is an example in which this advantage is further enhanced. The information of stage 1 and stage 2 is the same as in case 2, but the contents of the energy map stored in database 6A and that this energy map is used for energy saving effect calculation are different from case 2.

  In Case 1, the database 6A stores electricity usage data for motors other than the inverter-controlled motors of various capacities obtained economically. The user determines an appropriate capacity from the conventional electricity usage data, selects an effective operating amount for one electricity usage, and inputs it to the computing device 1. Thus, in stage 1 of case 1, data values on two maps selected from past similar cases are selected. A rough energy saving effect amount is calculated using the data of these maps. Here, since both maps are actually measured, they are referred to as assumed energy saving effects. The rough amount of energy saving effect is corrected in stage 3 as described above.

  In this manner, by generating information, the energy saving effect amount can be calculated for case 2 and / or both in combination with case 3 and displayed on the screen of screen display device 2.

  FIG. 10 shows data stored in the database 6A, which is the advance characteristic (experience value) obtained by the alternative replacement to the inverter control motor. FIG. 10 shows a flow rate (%) on the X axis, that is, an effective operating amount, and a required power (%), that is, an electric usage amount on the Y axis. FIG. 10 shows 15 examples from the characteristic A to the characteristic O, but the invention is not limited to these. These diagrams (curves) show past actual measurement values. In these diagrams, the characteristic L is one actually measured value by the inverter control motor.

In case 1, two operating characteristics are selected from similar examples similar to the design. One of the operating characteristics is the characteristic L. In stage 1 of case 1, for example, when characteristic L is selected,
Operation characteristic before energy saving: Select characteristic M Operation characteristic after energy saving: Select characteristic L Therefore, the energy saving effect is calculated by the difference between characteristic M and characteristic L depending on the operating condition. In this way, even when not actually measured, it is possible to calculate the approximate energy saving effect by properly selecting an example similar to the design, which has the effect of promoting the replacement with an inverter control motor. Arise.

  Even in stage 1 of case 2, an approximate energy saving effect can be calculated by selecting an example similar to the design. In Case 2, since the pre-energy-saving operation characteristic is used as the value measured in advance, the energy saving effect calculation can be performed more accurately and accurately than in Case 1. In this way, it is possible to shift from the case 1 stage to the case 2 stage.

  Case 3 employs the actual pre-energy-saving operation characteristics and post-energy-saving operation characteristics without using the experience values shown in FIG.

  In any case, in stage 2, the post-energy-saving operation characteristics of the actual machine are adopted, and depending on case 1 or case 2, the previously calculated energy-saving effect is accurately corrected at this stage. . Then, when the pre-energy-saving operation characteristic is actually measured for the actual machine, Case 3 is calculated and the accurate energy-saving effect is calculated and corrected.

So according to this example:

The conventional motor electricity usage data indicating the effective operating amount for the motor is stored, and the CO ₂ emission amount is calculated by using a predetermined CO ₂ emission coefficient for the CO ₂ emission state with respect to the electricity usage amount of the inverter control motor. stores calculation to calculation program, for CO ₂ reduction for CO ₂ reduction amount bid and energy savings are going to be stored unit price data to compare the energy saving effect amount bid.

In place of a motor other than the inverter control motor as the energy power consumption device (not necessarily a substitute), an arithmetic device that calculates the amount of energy saving effect on the operation status when the inverter control motor is replaced,
By selecting the electricity usage data of this arithmetic unit, the effective operation amount for any electricity usage is selected from the inverter electricity usage data stored in the database,
The effective operating amount with respect to the electric usage amount of the inverter electric usage data selected by the consumption energy amount determining means and the effective operating amount with respect to the actually measured electric usage amount of the inverter control motor are determined respectively, and the determined by the energy saving effect amount calculating means. A calculation program corresponding to the CO ₂ emission form is calculated by calculating the selected energy saving effect amount and the actually measured energy saving amount based on each of the energy consumptions that are calculated, and referring to the unit price data of the database by the reduced CO ₂ amount calculation means. The reduction CO ₂ amount is calculated from the selected and selected energy saving effect amount and the actually measured energy saving amount.

Then, one or both of the two calculated energy saving effect amounts and the two reduced CO ₂ amounts are displayed on the same screen on the screen display device.

  In the database 6, the electricity usage data of both is stored, the electricity usage data selection means selects the effective operating amount for any of the conventional motor electricity usage data, and the energy saving effect amount calculation means The assumed energy saving effect amount is calculated based on the effective operation amount with respect to the electricity usage amount selected by the conventional motor electricity amount usage data selection means, and the assumed energy saving effect amount is displayed on the same screen on the screen display device. Doing things.

And even in these examples,
A database to store the calculation program to calculate the CO ₂ emissions by using a predetermined CO ₂ emission factor for CO ₂ emissions form the electric consumption, CO ₂ reduction for CO ₂ reduction amount bid and energy saving Stores data comparing energy saving unit price for
The reduced CO ₂ amount calculation means of the arithmetic device uses the calculation program corresponding to any CO ₂ emission form with reference to the database, calculates the reduced CO ₂ amount from the energy saving effect amount, The calculation means calculates an energy saving amount converted value for the amount of CO ₂ reduction from the CO ₂ reduction unit price and the energy saving effect unit price, and the amount equivalent energy saving effect amount calculation means calculates the energy saving effect amount as the energy saving effect amount.
