Description

  The present invention relates to a thermal insulation effect simulation program and a thermal insulation effect simulation system for calculating an effect of a thermal insulation paint that is applied to a structure and suppresses temperature rise inside the structure due to solar radiation.

  In recent years, a phenomenon called a heat island has occurred in which the temperature in an urban area shows an abnormally high temperature compared with the surrounding area. Various measures have been studied to alleviate the heat island phenomenon, and as one of them, it is drawing attention to paint the structure with a thermal barrier paint. A thermal barrier coating is a coating that has high reflectivity with respect to solar radiation and heat insulation that reduces the inflow of heat from the outside to the inside of the structure.

  Since the thermal barrier paint reflects solar radiation, heat (referred to as heat inflow amount) flowing from the outside to the inside of the structure due to solar radiation can be kept low. Thereby, for example, the temperature rise of the roof of the structure is suppressed, and the relaxation of the heat island phenomenon can be expected. Moreover, the temperature rise in the room is also suppressed, and the power load related to the operation of the air conditioner can be reduced.

  Here, there is a technique for measuring how much the heat shielding paint reduces the amount of heat inflow (see, for example, Patent Document 1). This technique calculates the solar absorption rate of the thermal barrier paint, and calculates the heat inflow amount (throughflow heat amount) by a predetermined calculation formula based on the solar absorption rate.

  However, there is a problem that inputting numerical values such as solar radiation absorption rate into the calculation formula is complicated especially for non-experts such as general consumers. Because thermal insulation paints have different properties related to heat conduction such as solar absorptivity and thermal conductivity if the color and thickness of the coating are different, general consumers are among the many properties related to thermal insulation paints. The characteristics relating to what is to be painted must be selected, and even if the characteristics are selected, the heat inflow must be calculated using the complex formula. Moreover, even if the heat inflow amount is calculated, there is a problem that the general consumer has difficulty in realizing how much temperature reduction effect the numerical value brings.

  Hereinafter, the best mode for carrying out the present invention will be described. The description of the present embodiment is an exemplification, and the present invention is not limited to the following description.

<Embodiment 1>
The thermal insulation effect simulation program according to the present embodiment is designed so that when a thermal insulation paint is applied to a structure on which a normal paint has already been applied, if the thermal insulation paint is applied, the heat inflow that flows from the outside to the inside of the structure Calculate how much the amount is reduced. In addition, the paint already applied is called an old paint film. Moreover, a structure will not be specifically limited if it can receive solar radiation, For example, they are the land, the various buildings on the sea, a motor vehicle, a ship, etc.

  FIG. 1 is a functional block diagram of a computer that executes a thermal insulation effect simulation program according to the first embodiment. As shown in the figure, the computer 1 includes a CPU 2, a storage unit 3 such as a RAM and a hard disk drive, an input unit 4 such as a keyboard and a mouse, an output unit 5 such as a display, and a communication unit 6.

  The heat shielding effect simulation program is stored in, for example, a hard disk drive, read from the hard disk drive by the CPU 2, written in the RAM, and sequentially executed. In the heat shielding effect simulation program, data is input via the input unit 4, and data to be output is displayed on the output unit 5.

  FIG. 2 is a functional block diagram of the thermal insulation effect simulation program according to the first embodiment. As shown in the figure, the heat shielding effect simulation program 10 includes a data setting means 20, a candidate display means 21, a selection name acquisition means 22, a characteristic information search means 23, an area acquisition means 24, and a heat inflow calculation means 25. And display means 26. Each of these means 20 to 26 is implemented as a program executed by the computer 1. However, each of these means 20 to 26 is not limited to being executed as a program, and may be, for example, an individual program executed by each of a plurality of computers, or configured by hardware such as an electronic circuit. May be.

  The data setting means 20 causes the computer 1 to store the application portion information, the thermal barrier paint information, and the old paint film information in the storage means 3.

  The coated part information is information relating the coated part characteristic information related to the heat conduction of the coated part, which is a part to which the thermal barrier coating of the structure is applied, to the name of the coated part. More specifically, the coated part information is a combination of the coated part characteristic information and the coated part name so that the coated part characteristic information is uniquely determined when the coated part name is determined. Say. Accordingly, since there are various roof surface materials and heat insulating materials, the storage means 3 stores a plurality of applied portion information. If the name of a given applied portion is used as a search key, a plurality of applied portion information is stored. To-be-applied part characteristic information corresponding to the name can be obtained from the to-be-applied part information.

  The coated part characteristic information refers to, for example, the thickness and thermal conductivity of the coated part. When the portion to be coated is made of a surface material and a heat insulating material, the thickness and thermal conductivity of the surface material, the thickness of the heat insulating material and the heat conductivity are the portion to be coated characteristic information. As the name of the portion to be coated, for example, the material name of the portion to be coated, the film thickness, or a combination thereof can be used. In addition, a to-be-coated part is not necessarily limited to the site | part which receives solar radiation directly. For example, when a heat insulating material is provided on the roof of a building and a surface material is provided on the roof, the surface material and the heat insulating material are applied portions.

  The thermal barrier paint information is information obtained by associating thermal barrier paint characteristic information related to thermal conduction of the thermal barrier paint applied to the structure with the name of the thermal barrier paint. Specifically, the thermal barrier paint information is a combination of the thermal barrier paint characteristic information and the thermal barrier paint name so that once the thermal barrier paint name is determined, the thermal barrier paint characteristic information is uniquely determined. Say. Accordingly, since there are various types of thermal barrier paints, a plurality of pieces of thermal barrier paint information are stored in the storage means 3. If the name of a thermal barrier paint is used as a search key, a plurality of thermal barrier paints are stored. Thermal insulation paint characteristic information corresponding to the name can be obtained from the characteristic information.

  The thermal barrier paint characteristic information refers to, for example, the thickness of the thermal barrier paint when applied to a structure, the thermal conductivity of the thermal barrier paint, and the corresponding outside air temperature. The equivalent outside air temperature is a temperature obtained by converting the amount of solar radiation into an equivalent temperature and adding it to the outside air temperature in order to anticipate the influence of the amount of solar radiation hitting the surface of the structure. This considerable outside air temperature is determined based on the solar reflectance and solar radiation absorption rate of the thermal barrier coating. When multiple layers of thermal barrier coating are applied to the roof of the structure, the thickness and thermal conductivity are set for each layer. As the name of the thermal barrier paint, for example, the trade name, thickness, or color of the thermal barrier paint or a combination thereof can be used.

  The old paint film information is obtained by associating the old paint film property information relating to the heat conduction of the old paint film already applied to the structure with the name of the old paint film. Specifically, the old paint film information is a combination of the old paint film characteristic information and the old paint film name so that once the old paint film name is determined, the old paint film characteristic information is uniquely determined. Say. Accordingly, since there are various kinds of old paint films, a plurality of old paint film information is stored in the storage means 3, but if the name of a certain old paint film is used as a search key, a plurality of old paint films are stored. The old paint film characteristic information corresponding to the name can be obtained from the characteristic information.

  The old paint film characteristic information refers to, for example, the thickness of the old paint film applied to the structure, the thermal conductivity of the old paint film, and the corresponding outside air temperature. When the old paint film is coated on the roof of the structure in multiple layers, the thickness and thermal conductivity are set for each layer. As the name of the old coating film, for example, the trade name, thickness, or color of the old coating film or a combination thereof can be used.

  The data setting means 20 is mainly implemented for professionals such as painters. That is, the data setting means 20 is a means for an expert to input information about a part to be coated obtained from measurement, knowledge, and experience as the part to be coated information, heat shielding paint information, and old paint film information. is there.

  In addition, associating the application portion characteristic information with the application portion name is, for example, a hash table using the application portion name as a key and the application portion characteristic information as a value, the application portion name, and the application portion. Although it can be implemented using a relational database or the like in which the part property information is one record, it is not particularly limited thereto. The same applies to the association of the name / characteristic information of the thermal barrier paint and the name / characteristic information of the old paint film.

  Further, the coated part information, the thermal barrier paint information, and the old paint film information may be input and set via the input means 4 such as a keyboard, or may be input via a storage medium such as a CD-ROM. Or may be downloaded and set via the communication means 6.

  The candidate display means 21 causes the computer 1 to extract the name of the coated part from the coated part information stored in the storage means 3 and causes the output means 5 to display the extracted name of the coated part. The same applies to the heat-shielding paint information and the old paint film information, and the candidate display means 21 causes the computer 1 to extract the name of the heat-shielding paint from the heat-shielding paint information stored in the storage means 3 and extract the heat shield. The name of the paint is displayed on the output means 5, the name of the old paint film is extracted from the old paint film information stored in the storage means 3, and the name of the extracted old paint film is displayed on the output means 5. As described above, the candidate display means 21 displays the names of all the portions to be coated, the names of the heat-shielding paints, and the names of the old paint films stored in the storage means 3 on the output means 5.

  The arrangement and format of the names displayed on the output means 5 are not particularly limited, but it is preferable that the names are displayed in a format that allows the user to easily select one of the names. For example, the names may be displayed using a pull-down list that is one of the GUI parts for each of the portion to be coated, the thermal barrier coating, and the old coating film.

  The selection name acquisition unit 22 causes the computer 1 to acquire the selection name of the portion to be coated that is selected via the input unit 4 among the names of the plurality of portions to be coated displayed by the candidate display unit 21. The same applies to the name of the thermal barrier paint and the name of the old paint film, and the selected name acquisition means 22 is connected to the computer 1 via the input means 4 among the names of the thermal barrier paints displayed by the candidate display means 21. The selected name of the heat-shielding paint that has been selected is acquired, and the old paint that has been selected via the input means 4 among the names of the plurality of old paint films displayed by the candidate display means 21 Get the selected name of the membrane.

  The characteristic information search means 23 causes the computer 1 to read application portion characteristic information corresponding to the selected name of the application portion acquired by the selection name acquisition means 22 from the application portion information stored in the storage means 3. The same applies to the thermal barrier paint characteristic information and the old paint film characteristic information, and the characteristic information search means 23 is obtained by the selected name acquisition means 22 from the thermal barrier paint information stored in the storage means 3 in the computer 1. The thermal barrier paint characteristic information corresponding to the selected name of the paint is read, and the old paint corresponding to the selected name of the old paint film obtained by the selection name obtaining means 22 from the old paint film information stored in the storage means 3 The film characteristic information is read out.

  Here, since the to-be-coated part characteristic information is associated with the name of the to-be-coated part, the name of the to-be-coated part that matches the selected name of the to-be-coated part is retrieved from the storage means 3, thereby The to-be-coated part characteristic information corresponding to the selected name is specified. The same applies to the thermal barrier paint characteristic information and the old paint film characteristic information.

  The area acquisition unit 24 causes the computer 1 to acquire the area of the application portion via the input unit 4. The acquired area is used by a heat inflow calculating unit 25 described later. In addition, although you may acquire the area of a to-be-coated part directly, for example, you may acquire the width and length of a to-be-coated part, respectively, and may acquire an area indirectly by multiplying the acquired width and length. Good.

  The heat inflow amount calculating means 25 causes the computer 1 to calculate the heat inflow amount in the thermal barrier paint and the heat inflow amount in the old paint film. The amount of heat inflow in the thermal barrier paint refers to the heat that flows from the outside to the inside of the structure when the thermal barrier paint is applied to the coated portion of the structure. Further, the heat inflow amount in the old coating film refers to heat flowing from the outside to the inside of the structure in which the old coating film is coated on the portion to be coated.

  The amount of heat inflow in the thermal barrier paint is obtained by substituting the area information acquired by the area acquisition unit and the coated part characteristic information and thermal barrier paint characteristic information read by the characteristic information search unit 23 into a predetermined calculation formula. Calculated. Similarly, the amount of heat inflow in the old coating film is obtained by adding, to a predetermined calculation formula, the to-be-coated part characteristic information and the old coating film characteristic information read by the characteristic information search means 23, and the area acquired by the area acquisition means. Substituted and calculated. A specific calculation formula will be described later.

  The display means 26 causes the output means 5 to display the heat inflow amount in the thermal barrier paint and the heat inflow amount in the old coating film calculated by the heat inflow amount calculation means 25 on the computer 1. The display means 26 can display the heat inflow amount in various ways. For example, the display means 26 compares and displays the heat inflow amount in the thermal barrier paint and the heat inflow amount in the old paint film. Furthermore, the display means 26 converts each heat inflow amount into another scale and displays it. For example, based on the amount of heat inflow in the old paint film and the amount of heat inflow in the heat-shielding paint, the temperature inside the structure before and after applying the heat-shielding paint to the coated part can be calculated and displayed. Displayed in terms of electricity charges.

  Next, a processing procedure of the heat shielding effect simulation program will be described. FIG. 3 is a diagram illustrating a processing flow of the heat shielding effect simulation program according to the first embodiment. As shown in the figure, the computer 1 executes seven processes. First, the data setting process (step S1) which memorize | stores to-be-coated part information, thermal insulation paint information, and old coating film information is performed. Next, a candidate display process (step S2) for displaying the name of the application part or the like is executed, and a selection name acquisition process (step S3) for acquiring a selection name of the application part or the like based on this display is executed. . Furthermore, the area acquisition process (step S4) which acquires the area of a to-be-coated part is performed. Steps S1, S2, and S4 are executed in an arbitrary order according to the user's selection.

  Then, a characteristic information search process (step S5) for searching the application part characteristic information and the like from the selected name of the application part acquired in step S3 is executed, and the application part characteristic information, the thermal barrier paint characteristic information, and the old coating are obtained. A heat inflow amount calculation process (step S6) is performed to calculate the heat inflow amount in the thermal barrier paint and the heat inflow amount in the old coating film from the film characteristic information and the area of the coated portion. Finally, a display process (step S7) for displaying each heat inflow amount on the output means 5 is executed.

  The data setting process (step S1) is executed at least once by a specialist such as a painter, and the processes subsequent to the candidate display process (steps S2 to S7) are owned by the structure to be coated with the thermal barrier paint. It is executed whenever a general consumer such as a consumer tries to calculate the heat inflow amount under various conditions.

Hereinafter, each process will be described in detail.
[Data setting process]
The data setting process is executed by the data setting means 20 and is a process for storing the application portion information, the thermal barrier paint information, and the old paint film information in the storage means 3.

  FIG. 4 is a processing flow of data setting processing. As shown in the figure, the data setting means 20 includes the name of the part to be coated and the characteristic information of the part to be coated, the name of the thermal barrier paint and the thermal barrier paint characteristic information, the name of the old paint film and the old paint film characteristic information. An input form for inputting is displayed on the display (step S10). Next, the data setting means 20 receives the name of the part to be coated and the characteristic information of the coated part, the name of the heat shielding paint and the characteristic of the heat shielding paint, and the old information from the user of the heat shielding effect simulation program via a keyboard or the like. The name of the coating film and the old coating film characteristic information are input (step S11).

  Then, the data setting means 20 causes the storage means 3 to store the application part characteristic information input in the input form in association with the name of the application part as application part information. Similarly, the thermal barrier paint characteristic information input in the input form is stored in the storage means 3 as the thermal barrier paint information in association with the name of the thermal barrier paint, and the old paint film characteristic information input in the input form Is associated with the name of the old paint film in the storage means 3 as old paint film information (step S12).

  Data input in the data setting process is mainly performed by an expert such as a painter. If the storage means 3 is a medium that can be stored semi-permanently, such as a secondary storage device such as a hard disk drive, the data setting process only needs to be performed once. What is necessary is just to perform from the candidate display process demonstrated below.

  Table 1 shows an example of applied portion information about the surface material constituting the applied portion.

  Table 1 shows a total of ten pieces of applied portion information about the surface material. The coated part number is a number for identifying each coated part information. For example, the application part information whose application part information number is “1000” is a name indicating the material and thickness of the application part, such as “concrete (t = 50 mm)”. In the coated part characteristic information, the film thickness is “50” (unit: [mm]), and the thermal conductivity is “1.38” (unit: [kcal / m · h · ° C.]).

  Table 2 shows an example of applied portion information about the heat insulating material constituting the applied portion.

  Table 2 shows a total of six parts to be applied information about the heat insulating material. For example, the application part information whose application part information number is “1011” is a name indicating the material and thickness of the application part, such as the name of the application part “foam urethane (t = 25 mm)”. In the coated part characteristic information, the film thickness is “25” (unit: [mm]) and the thermal conductivity is “0.05” (unit: [kcal / m · h · ° C.]).

  Table 3 shows an example of thermal barrier paint characteristic information.

  Table 3 shows a total of 13 pieces of thermal barrier paint information. The thermal barrier paint information number is a number for identifying each thermal barrier paint information. For example, the thermal insulation paint information whose thermal insulation paint information number is “2000” is the name indicating the color of the coated part and the product name, such as “white (eco cool)” of the thermal insulation paint. Information on the properties of the coated part is that the primer film thickness is “0.05” (unit: [mm]), the primer thermal conductivity is “0.43” (unit: [kcal / m · h · ° C.), Thickness is “0.1”, middle coating thermal conductivity is “0.18”, top coating thickness is “0.06”, top coating thermal conductivity is “0.27”, and equivalent outside temperature is “40” (units) Is [° C.]).

  The film thickness and thermal conductivity are set for each primer, intermediate coating, and top coating, and this is due to the coating method of the thermal barrier paint. In other words, when applying a thermal barrier coating to a structure, three steps, a primer coating step, a thermal barrier coating intermediate coating step, and a thermal barrier coating top coating step, are performed. Thickness and thermal conductivity are set.

  Table 4 shows an example of old paint film characteristic information.

  Table 4 shows a total of 13 pieces of old paint film information. The old paint film information number is a number for identifying each old paint film information. For example, the old paint film information whose old paint film information number is “3000” is a name indicating the material and color of the coated part, such as “Color Totan (con color)” of the thermal barrier paint, According to the previous coating film characteristic information, the primer film thickness is “0.05” (unit: [mm]), the primer thermal conductivity (unit: [kcal / m · h · ° C.]) is “0.43”, and the top coat The film thickness is “0.06”, the top coating thermal conductivity is “0.35”, and the corresponding outside air temperature is “75” (unit: [° C.]).

  The film thickness and thermal conductivity are set for each primer and top coat, which is due to the coating method of the old paint film. In other words, since the old paint film applied to the structure was formed from two steps, the primer application process and the coating process of the old paint, the film thickness and thermal conductivity were set for each primer and overcoat. ing.

  In this way, in the data setting process, the part to be applied characteristic information, the thermal barrier paint characteristic information, and the old paint film characteristic information are associated by the name of the part to be applied, the name of the thermal paint, and the name of the old paint film. Is remembered.

[Candidate display processing]
The candidate display process is executed by the candidate display means 21 and is a process for causing the output means 5 to display the name of the portion to be coated, the name of the thermal barrier paint, and the name of the old coating film.

  FIG. 5 is a processing flow of candidate display processing. As shown in the figure, the candidate display means 21 includes the names of all the parts to be coated, the names of the heat shielding paints and the old ones among the information on the parts to be coated, the heat shielding paint information and the old paint film information stored in the storage means 3. The name of the coating film is read (step S20). Next, they are shaped into a predetermined arrangement and format and displayed on the output means 5 (step S21).

  An example of the name of the part to be applied, the name of the thermal barrier paint, and the name of the old paint film displayed on the display as an example of the output means 5 is shown in FIG. FIG. 6 is a screen of the name of the part to be applied, the name of the thermal barrier paint, and the name of the old paint film displayed on the output means. In this embodiment, each name is displayed by a pull-down list that is one of GUI parts. As shown in FIG. 6A, the pull-down list 30 displays “Rashid Red” which is one of the names of all the old paint films. This indicates that the displayed “Rashid Red” is selected, that is, the selected name. As shown in FIG. 6B, a list 30b of all old paint film names is displayed by clicking the pull-down button 30a with a mouse, and if any one, for example, “Moss Green” is clicked with the mouse. “Moss Green” is the selected name.

  The same applies to other names, the name of the surface material constituting the part to be coated is displayed by the pull-down list 31, the name of the heat insulating material constituting the part to be coated is displayed by the pull-down list 32, and the name of the heat shielding paint. Is displayed by a pull-down list 33. Then, by clicking on the pull-down buttons 31a to 33a with a mouse, the names of the surface materials constituting the coated part, the names of the heat insulating materials constituting the coated part, and the names of the thermal barrier paint are displayed in a list. You can choose one.

[Selected name acquisition processing]

The inflow amount is displayed on the display (step S71).

  Here, each heat inflow amount can be displayed in various modes. 13 and 14 are display examples of the heat inflow amount in the old coating film and the heat inflow amount in the thermal barrier coating. As shown in FIG. 13, the heat inflow amount in the old coating film and the heat inflow amount in the thermal barrier paint can be compared and displayed. Further, each heat inflow amount may be converted into, for example, kilowatt hour (KWh) and displayed. Further, the ratio between the heat inflow amount in the old coating film and the heat inflow amount in the thermal barrier paint may be calculated, and this result may be displayed as the effect of reducing the heat inflow amount when the thermal barrier paint is applied.

Further, a quotient obtained by dividing the heat inflow amount in the heat-shielding paint, the converted electric power charge, etc. by the area of the coated portion of the structure may be displayed as the heat inflow amount per unit area or the electric power charge.

  In the heat shield effect simulation program described above, the subject to be applied information, the heat shield paint information, and the old paint film information are stored in the storage means 3 by a data setting process by an expert or the like. On the other hand, if the heat shield effect simulation program selects the part to be coated of the structure to which the thermal barrier paint is to be applied, the name of the old paint film, and the name of the thermal paint to be painted, The heat inflow amount and the heat inflow amount in the thermal barrier coating are displayed to general consumers.

  In other words, the general customer does not need to examine and input the coated part characteristic information, the thermal barrier paint characteristic information, and the old coating film characteristic information necessary for calculating the heat inflow amount, and the name of the coated part, As long as you choose an appropriate one from the name of the old paint film and the name of the thermal barrier paint, it will be based on accurate information on the part to be applied, thermal barrier paint information, and old paint film information set in advance by an expert. The calculated heat inflow amount can be obtained. In this way, for general consumers, avoiding the hassle of inputting various values into the calculation formulas shown in Equations 1 and 2, the amount of heat inflow when applying a thermal barrier paint is reduced. Can be easily obtained.

  In addition, in the display process, the heat inflow in the old paint film and the heat inflow in the thermal barrier paint are displayed after being compared or converted to another scale such as the degree of reduction in power charges and room temperature. The difference between the case where the heat-shielding paint is applied and the case where the old paint film is left is obvious. In other words, it is easy for general consumers to easily determine the effect of applying a thermal barrier paint to the coated part of the structure, and to easily determine whether or not to actually apply the thermal barrier paint. Become.

  In addition, a usage mode in which a sales representative of a painter operates a heat shielding effect simulation program on behalf of a customer is also possible. In this case, the sales representative interviews the customer and inputs the name of the part to be coated, the name of the old coating film, and the name of the thermal barrier paint into the thermal insulation effect simulation program that corresponds to the customer's current situation / request. If this is the case, the effect of applying the thermal barrier paint can be quickly communicated to the customer.

  In the display process, the heat inflow amount in the old coating film and the heat inflow amount in the heat-shielding paint are compared and displayed on the output means 5, but it is not always necessary to display them in comparison. The amount of heat inflow may be displayed alone. Even in this case, it is possible to know the effect of the thermal barrier paint while avoiding the complexity of calculating the heat inflow amount in the thermal barrier paint.
