Yes.

  FIG. 2 is a flowchart for explaining the operation of the heat countermeasure device introduction energy saving estimation evaluation system according to the embodiment of the present invention. In the description of FIG. 2, FIG. 1 will be referred to as appropriate.

  In FIG. 2, the heat countermeasure device introduction energy saving trial evaluation system (hereinafter abbreviated as “this system”) according to the embodiment of the present invention first shows the relationship between the heat countermeasure device and the unit price in advance in the heat in the DB server 30. It is set and stored as master data in the exchanger type DB31. For example, the outline of the setting contents is as shown in FIG. FIG. 3 is a diagram illustrating an example of the correlation between the heat exchanger and the unit price.

  In FIG. 3, a heat exchanger is taken as an example of the heat countermeasure device. This time, the relationship between the unit prices of the five types of heat exchangers is as follows: (1) Heat exchanger A: 100,000 [yen], (2) Heat exchanger B: 200,000 [yen], (3) Heat exchanger C: 300,000 [Yen], (4) Heat exchanger D: 400,000 [Yen], (5) Heat exchanger E: 500,000 [Yen] The contents can be registered (step S301).

  Further, the relationship between the piping material and the m (meter) unit price is set and stored as master data in the piping material DB 32 in the DB server 30. For example, the outline of the setting contents is as shown in FIG. FIG. 4 is a diagram showing an example of the correlation between piping material and metric unit price.

  This time, the relationship between the unit price of 5 types of piping materials is as follows: (1) Vinyl chloride: 2,000 [yen / m], (2) Copper pipe: 3,000 [yen / m], (3) Steel pipe: 4,500 [yen / m m], (4) Stainless steel pipe: 5,000 [yen / m], and (5) Polyethylene: 4,000 [yen / m]. Registration is possible (step S302).

  Further, the relationship between the area and the artificial unit price is set and stored as master data in the artificial unit price DB 33 classified by area in the DB server 30 in advance. For example, the outline of the setting contents is as shown in FIG. FIG. 5 is a diagram illustrating an example of a correlation between a region and an artificial unit price. In this example, the relationship between the 10 regions and the artificial unit price is set and registered as 9,000 [yen / day], but in reality, the contents of more regions can be registered (step S303). ).

  Next, the data of the factory model DB 34 in the DB server 30 is acquired via software that accesses the communication unit 42 in the Web server 40 of this system, for example, Apache (registered trademark), IIS (registered trademark), etc. Then, a factory model diagram before process improvement is created on the screen of the client terminal 10, and data necessary for energy saving evaluation calculation is input to the factory model diagram. For example, the factory model shown in FIG. 6 is created as a factory model diagram before process improvement. FIG. 6 is a diagram showing an example of a factory model diagram before process improvement according to the embodiment of the present invention.

  The factory model is a combination of two locations: the location where hot wastewater is discharged from the facility 2 as the stream 3 and the location where the low temperature stream 2 is evaporated by the boiler and the steam from the stream 1 is used in the facility 1 A facility is assumed. Of course, the boiler is supplied with fuel as a stream from the fuel tank. Then, specification values (fuel type, boiler efficiency, etc.) are set in the boiler, and attribute data such as components, temperature, pressure, and flow rate are input to all streams (step S304).

  The input value check unit 51 for the created factory model in the application server 50 of this system determines that there is no inconsistency between the created factory model and the input value. If inconsistency is found, the process of step S304 is performed again (step S305).

  If no inconsistency is found, the energy saving evaluation item trial calculation unit 52 in the application server 50 of this system uses the energy saving evaluation item ((1) Primary energy consumption [MWh / year] in the factory model before process improvement. ], (2) CO2 emissions [t-CO2 / year], (3) Energy cost [thousand yen / year]) (step S306). Note that the result of the trial calculation is stored in a buffer memory (not shown) in the application server 50.

  Next, the data of the factory model DB 34 in the DB server 30 is acquired via software that accesses the communication unit 42 in the Web server 40 of this system, and the factory model diagram after the process improvement is displayed on the screen of the client terminal 10. The data required for energy saving evaluation calculation is input to the factory model diagram after process improvement. For example, the factory model shown in FIG. 7 is created as a factory model diagram after process improvement. FIG. 7 is a diagram showing an example of a factory model diagram after process improvement according to the embodiment of the present invention.

  The factory model after this process improvement is an improvement of the factory model created in FIG. 6, and heat recovery from the hot effluent that has been discharged as stream 3 from the equipment 2 by introducing a heat exchanger is performed. The stream 21 is heated to obtain a stream 21 and then evaporated with a boiler so that the steam of the stream 1 is used in the facility 1. By doing so, it is possible to realize energy saving while suppressing the fuel cost for the boiler. In this case, in addition to the boiler specification values and attribute data such as stream components, temperature, pressure, and flow rate input in step S304, the pipe distance is input to the added stream location. In this example, (1) Stream 2: 50 [m], (2) Stream 21: 50 [m], (3) Stream 3: 150 [m], (4) Stream 31: 150 [m] input. Further, “equipment 2” is set as an existing facility that can be physically moved, and the target investment payback period is set to 1.00 [year] (step S307). The target investment payback period is set to a common value on the site side.

  The input value check unit 51 for the created factory model in the application server 50 of this system determines that there is no inconsistency between the created factory model and the input value. If inconsistency is found, the process of step S307 is performed again (step S308).

  If no inconsistency is found, process improvement is performed by the energy conservation evaluation item trial calculation unit 52, the energy cost reduction trial calculation unit 53 and the approximate cost trial calculation unit 54 related to the addition of heat countermeasure equipment and piping in the application server 50 of this system. The energy saving evaluation items in the later factory model are calculated (step S309). In the calculation of energy saving evaluation items, (1) energy cost reduction, (2) estimated cost for adding heat countermeasure equipment and piping, and (3) years of investment recovery are calculated. In this example, (1) the energy cost reduction amount is 1,873 [thousand yen / year], and (2) the estimated cost for adding heat countermeasure equipment is, for example, 100,000 [ Yen], the material cost for additional piping is 1,600,000 [yen] using a total of 400m of polyethylene, and the man-made cost for construction is 50 man-days and 450,000 [yen]. The investment payback period is 1.15 [years] by calculating the total amount of 2,150 [thousand yen] ÷ energy cost reduction amount of 1,873 [thousand yen / year] in the energy saving evaluation item trial calculation section 55 in the application server 50 of this system. (Step S310).

  Next, the trial calculation result stored in the buffer (not shown) of the energy saving evaluation item of the factory model before the process improvement is compared with the calculation result of the energy saving evaluation item of the factory model after the process improvement. It is determined whether the estimated investment payback period falls within the investment payback set in step S307. If not, the process of step S312 is executed. If it is settled, the process of step S313 is executed without executing the process of step S312. In this example, since the investment payback year exceeds the set value, the process of step S312 is executed (step S311).

  Then, the pipe length / movement distance estimation unit 56 in the application server 50 of this system calculates the pipe length so as to fall within the set investment recovery. In this example, from the calculation result, if the pipe length of the stream 3 is changed from 150 [m] to 80 [m], the set investment recovery can be achieved (step S312).

  And finally, the energy saving evaluation items calculated above, the amount of energy cost reduction, the estimated cost of adding heat countermeasure equipment and piping, the result of trial calculation of investment recovery years, and the pipe length or equipment accompanying the movement of existing equipment The correlation between the travel distance and the investment payback years is presented on the user's terminal screen.

  FIG. 8 is a diagram illustrating an example of a terminal screen display of a trial calculation evaluation result by the heat countermeasure device introduction energy saving trial calculation evaluation system according to the embodiment of the present invention. In the example shown in FIG. 8, in addition to the evaluation items before and after the process improvement, the amount of energy cost reduction, the approximate cost for adding heat countermeasure equipment and piping, and the estimated result of the investment recovery years are displayed in a table format, The correlation between the distance between the piping connecting the existing equipment and the heat exchanger and the investment payback years is shown as a graph, and in order to keep the investment payback year at the target 1.00 [year] from the graph, the pipe distance is indicated by a diagonal line It is understood that it is necessary to be within.

  In this example, for example, if the investment payback period is to be reduced to 1.00 [year], the piping distance between the existing equipment and the heat exchanger must be close to 150 [m] to 80 [m] ( Step S313).

  In order to display the equipment travel distance and investment payback period in the graph shown in FIG. 8, the vertical axis used as the investment payback period is changed to the horizontal axis, and the horizontal axis used now as the pipe distance is changed to the equipment move distance. If the scale is set on the vertical axis, the graph can be displayed with the same straight line as the present.

  And when the equipment movement distance is scaled up based on the estimated pipe length 150 [m] of stream 3 before process improvement and the investment payback period is set to 1.00 [year], The equipment movement distance is 150 [m] −80 [m] = 70 [m]. In that case, 80 [m] is the estimated value of the piping distance between the existing equipment and the heat exchanger when the investment payback period is set to 1.00 [year] as described above.
