Description

The present invention is, detached houses and be in an environment subjected to energy supply by a so-called gas such each dwelling unit in the apartment, such applications degrades applications exploded instrumentation consumption for each application of the gas in the environment 置及 beauty applications decomposer It is about.

  Conventionally, energy saving is demanded from the viewpoints of conservation of global resources and economic efficiency. For this reason, it is required to reduce energy consumption of facilities and devices themselves and to save energy in terms of operation. In industrial facilities that consume a large amount of energy in factories and the like, various devices have been devised for monitoring energy consumption for each facility and for rational operation.

  On the other hand, equipment used for each residential unit in the consumer sector usually does not have a function for monitoring such energy consumption. Energy conservation activities at home, etc. are carried out by qualitative acts such as turning off the light frequently or lowering the set temperature of heating, but there are no indicators that show energy conservation activities as a result. It is difficult to realize. In such a situation, there is a lack of motivation for energy conservation activities, and the fact is that it relies on multiple motivations such as education, customs, obligations and lifestyle ideas, and quantitative energy conservation measures have not progressed much. .

  On the other hand, the applicant of the present application evaluates the tendency of his / her behavior in Patent Document 1 by inputting and accumulating the amount of consumption for each energy type and expressing it by comparison with past data and other people's data. A life improvement support system is proposed. This allows each person to look back on his actions and use it to improve energy conservation activities.

  However, it is considered that energy saving activities will be facilitated by knowing not only the consumption trend for each energy type, but also how much it was used for which purpose.

  On the other hand, a load centralized control system is known as one that supports such human efforts (Non-Patent Document 1). The above-mentioned load centralized control system is a power supply company that remotely measures the watt-hour meter at home and accumulates the data. At home, this data is accessed via a telephone line, etc. Can be seen on a monitor screen in the home. According to this system, it is possible to generate a motive for power saving that allows the consumer to know that the power consumption has increased.

  Furthermore, Patent Document 2 discloses a load type analyzer that can specifically display the energy consumption tendency in units of households or offices using a computer. According to Patent Document 2, the load type analysis device can display energy consumption separately for each consumption application such as hot water supply and lighting, and can diagnose energy propensity from the display.

  Since it is sufficient to grasp the general tendency of the above energy consumption propensity, a suitable length (for example, one month) is set for the unit period of calculation. Depending on the application, the energy consumption tendency depends to some extent on time. For example, the energy for cooling is concentrated in the summer and the energy for heating is concentrated in the winter.

  However, the configuration described in Patent Document 2 mechanically specifies the month in which the energy consumption is lowest in one year, and sets the energy consumption in the lowest month in which the energy consumption is lowest in the kitchen, lighting, Considering that it is due to non-cooling and heating loads such as power, the consumption by non-cooling and heating loads in other months is analyzed. Therefore, if there is a month with significantly less energy consumption compared to the normal month, such as when a house is left for a month due to a long trip, etc., the month is judged as the lowest month and the analysis is performed. In this case, the analysis result may be significantly different from the actual situation.

The present invention, even in the presence of different energy consumption periods usually aims to provide a use exploded instrumentation 置及 beauty applications decomposer capable of analyzing applications energy consumption in line with actual conditions.

  (1) The application decomposition apparatus of the present invention divides one year into a plurality of unit periods, and uses the total consumption of gas consumed in an environment where energy is supplied by gas for each unit period as a hot water supply application in the environment. A use decomposing apparatus capable of decomposing use into gas consumption for each use of consumption, kitchen use consumption, and heating use consumption, wherein the hot water supply use consumption and the kitchen use in each unit period A two-use disassembly table that defines a ratio to consumption, a plurality of continuous unit periods, and one unit period belonging to a specific period assumed as a period in which heating is not used in the environment as a reference period, A ratio table that defines the ratio of consumption of hot water supply for the remaining unit period to the consumption of hot water supply for the reference period, and the total consumption of gas actually used in the environment in one year for each unit period And a gas use decomposition unit that decomposes the use of the total consumption of gas in each unit period stored in the storage unit, wherein the gas use decomposition unit is a gas for the specific period. Based on information on consumption, the kitchen usage estimation means for estimating the kitchen usage consumption for each unit period, and the hot water usage usage for the specific period based on the estimated value of the kitchen usage consumption obtained by the kitchen usage estimation means And a hot water supply usage estimation means for approximating hot water usage usage in a non-specific period other than the specific period based on the approximate value of the kitchen usage consumption, the ratio table and the two-use decomposition table, Based on the approximate value of the hot water use consumption during the non-specific period obtained by the hot water supply use estimation means and the approximate value of the kitchen use consumption obtained by the kitchen use approximate means, the heating use consumption during the non-specific period amount Characterized in that it and a heating applications estimate means to estimate.

  According to the above configuration, not only a single unit period but also a plurality of consecutive unit periods assumed as periods in which heating with large seasonal variation is not used among unit periods obtained by dividing a year into a plurality of divisions. Based on the information regarding the gas consumption of the specific period, the kitchen usage consumption for each unit period, that is, the kitchen usage consumption for the whole year is estimated. Therefore, not only can the seasonal fluctuation factors be excluded, but it is possible not only to estimate the consumption of kitchen use with high accuracy, but also when there is a gas consumption period that is clearly different from normal daily life, without being disturbed by that period. It is possible to analyze the usage of gas consumption according to the actual situation. In detail, even if there is a long-term absence in a unit period in a non-specific period and energy consumption is extremely low, or even if there is a long-term absence in a unit period belonging to a specific period, the entire specified period Since the consumption for kitchen use is estimated based on this, the influence can be made extremely small. Not only that, but the estimated value of consumption for hot water supply and consumption for heating use will be estimated based on the estimated value of consumption for kitchen use in this way. Even so, it can be broken down into highly relevant consumption in line with the actual situation.

  (2) In view of this point, the kitchen usage estimation means is defined in a total usage amount of at least a part of the unit period stored in the storage unit and a two-use decomposition table. Estimate the average kitchen usage for at least some unit periods within the specified period based on the proportion of the kitchen usage for at least some unit periods within the specified period. It is preferable to use an approximate value of consumption for kitchen use during the period.

(3) Moreover, the said hot water supply use estimation means uses the ratio prescribed | regulated to the said two use decomposition | disassembly table and the ratio prescribed | regulated to the said ratio table, and the consumption amount of hot water supply use of each unit period which belongs to the said non-specific period. Based on the first rough calculation means for rough estimation and the ratio defined in the two-use decomposition table, the consumption of hot water supply in each unit period from the total consumption of each unit period belonging to the non-specific period stored in the storage unit Second estimation means for estimating the amount and consumption for kitchen use, and determination means for determining which of the first estimation means and the second estimation means to use Is preferred.

  According to this, since the seasonal table of the hot water supply usage is estimated in advance in the ratio table, and the first approximate means for estimating the hot water usage consumption for each unit period based on the ratio table is provided, The consumption of gas consumption can be accurately decomposed in the consumption of hot water supply, which has a large consumption change range and often reflects the life stage and preference of each household. On the other hand, by simply decomposing the gas consumption for each unit period based on the ratio table, if the consumption of hot water supply in the target environment is very small compared to the approximate value, the results will be significantly different from the actual situation. It can happen. Therefore, the above application disassembling apparatus includes a second approximating means for approximating these application consumptions using a two-use decomposition table that preliminarily defines a ratio between hot water use consumption and kitchen use consumption. It has a judgment means to judge which one of the approximate result by the first approximate means and the approximate result by the second approximate means is to be adopted, and by adopting the most suitable approximate value by the judgment means, the deviation from the actual situation Therefore, it is possible to perform application disassembly that avoids the problem.

  (4) The determination means includes a total consumption amount of each unit period stored in the storage unit, and a sum of approximate values of the kitchen usage consumption and the hot water supply usage consumption of the unit period by the first estimation means. If the total consumption is larger, the result of the rough estimation by the first roughening means is adopted, and the sum of the rough values by the first roughening means is larger. It is preferable to employ the result of the approximation by the second estimation means.

  The approximate result by the first approximating means is the total value of the calculated values based on the ratio table and may exceed the actual measured value in some cases. However, according to the above configuration, the total consumption is the actual measured value. An estimated value exceeding the value is judged to be different from the actual situation. On the other hand, since the second approximating means decomposes the total consumption based on the two-use decomposition table, the total value of the approximate values by the second approximating means is the total consumption itself and exceeds the total consumption. Must not. In this way, by using the approximate value by the second approximate means only when the approximate value by the first approximate means is clearly different from the actual situation, the gas consumption pattern due to the absence of a certain temporary period or a change in living conditions In general, it is possible to flexibly cope with a situation in which consistency cannot be achieved with only the ratio table, such as a change in the ratio.

(5) In addition, the first estimation means multiplies the total consumption amount of the reference period stored in the storage unit by a ratio of consumption amount of hot water supply for the reference period specified in the dual-use decomposition table. Estimate the consumption of hot water supply for the reference period and multiply the approximate value of the consumption of hot water supply for the reference period by the ratio specified in the ratio table to use the consumption of hot water for each unit period belonging to the non-specific period It is preferred to approximate each amount.

  Seasonal fluctuations are anticipated in the ratio table in advance, so by multiplying the approximate value of hot water use consumption for the base period by the ratio in the ratio table for each unit period, the hot water use consumption for each unit period It is possible to incorporate the effects of fluctuations.

  (6) In addition, the second estimation means distributes the total consumption of the unit period belonging to the non-specific period to the ratio of the unit period specified in the dual-use decomposition table, so that the unit period It is preferable to estimate the consumption for kitchen use and consumption for hot water supply. In the two-use decomposition table, the ratio of each use consumption is defined by the two relative relations of the hot water use consumption and the kitchen use consumption in each unit period, and the total consumption is calculated based on the ratio. Disassembled into consumption for hot water supply and consumption for kitchen. For this reason, even if the total consumption of the unit period temporarily decreases due to the absence of a temporary period, at least the total consumption can be broken down into these two usage consumptions, It is also possible to cope with changes in gas consumption patterns due to changes in gas.

  (7) In addition, the heating use estimation means is a sum of an approximate value of hot water use consumption and an approximate value of kitchen use consumption, which is adopted based on the result of determination by the determination means, from the total consumption of the unit period. It is preferable that a value obtained by subtracting is used as an approximate value of the heating usage consumption of the unit period. According to this, after properly determining the consumption for kitchen use with little seasonal variation and the consumption for hot water supply that needs some seasonal variation, the consumption for heating use with the largest fluctuation in the total annual consumption is calculated. It can be estimated and the heating consumption can be estimated appropriately.

  (8) In addition, when there are a plurality of candidates for the reference period among the unit periods, the gas application decomposition unit recognizes a unit period having the largest total consumption among the candidates as the reference period. It is preferable to have an authorization means to do. According to this, the unit period in which the seasonal variation factor of hot water supply is eliminated as much as possible becomes the reference period, and thereby it is possible to more appropriately estimate the consumption amount not only for hot water supply use but also for heating use.

  (9) Further, the gas use decomposition unit is configured to obtain the water supply temperature acquisition unit capable of acquiring the temperature of the water supply system supplied to the environment in each unit period, and the water supply temperature acquired by the water supply temperature acquisition unit. It is preferable to include a calculation unit that calculates a ratio of the consumption amount of the hot water supply in the dual use decomposition table.

  The gas consumed for hot water supply is mainly consumed by heating tap water. The consumption amount of the hot water supply application varies depending on the set temperature and the amount of hot water supply, but also varies depending on the water temperature of the tap water. According to the above configuration, the temperature of the water supply (supply water temperature) is acquired by the supply water temperature acquisition means, and each usage consumption is calculated by the two-use decomposition table using the supply water temperature. In other words, by adding the water supply temperature as a factor for determining the ratio of hot water supply usage to the approximate estimation of consumption of hot water supply usage, the accuracy of the ratio of consumption for hot water usage per unit period in the two-use decomposition table and the ratio table can be increased. Therefore, it is possible to optimize the ratio with the consumption for kitchen use.

  (10) Moreover, it is preferable that the said water supply temperature acquisition means estimates the said water supply temperature based on the temperature of the area | region where the said environment exists. According to this, it is possible to simplify the calculation of the feed water temperature by estimating the feed water temperature, which is difficult to actually measure in the target environment, from the air temperature.

  (11) In addition, the gas use decomposition unit removes the oldest unit period in accordance with the input of the total consumption of a new unit period, adds the new unit period, and excludes the oldest unit period. It is preferable to provide a table updating means for updating the two-use decomposition table and the ratio table.

  As described above, the usage of each unit period is disassembled depending on whether there is a seasonal variation factor or not, and therefore the usage of the total consumption of one unit period such as only the latest unit period is decomposed. Also, a two-use disassembly table and a ratio table for a period of one year including at least the one unit period and the reference period are required. According to the above configuration, when the total consumption of the latest unit period is decomposed for use, the two-use disassembly table and the ratio table are updated in the latest one-year period including the unit period. As a result, actual conditions such as the water supply temperature of the latest unit period can be reflected in the construction of each table, and each table can be created appropriately.

  (12) Further, it is preferable that the application disassembling apparatus of the present invention further includes display means for displaying only the result of the application disassembly of the total consumption amount in the latest unit period of the unit periods. As described above, the table for the past year including the unit period can be updated, so that the usage decomposition for the past year can be reconstructed. However, what the user wants to confirm most is the latest unit period. It is a result of the use decomposition | disassembly in. Therefore, by providing the above-mentioned display means, the user can confirm the result of the use decomposition in the latest unit period that the user most wants to confirm. Alternatively, the visibility of the user can be improved by hiding the result of the use decomposition of each unit period over the past year that is not necessary for the user to be displayed.

(14) The application decomposition program of the present invention divides one year into a plurality of unit periods, and uses the total consumption of gas consumed in an environment where energy is supplied by gas for each unit period as a hot water supply application in the environment. An application decomposition program for causing a computer to execute an application decomposition process that can be decomposed for each of gas consumption of consumption, kitchen application consumption, and heating application consumption. 1 belonging to a specific period consisting of a two-use disassembly table that defines a ratio between the hot water supply use consumption and the kitchen use consumption in a period, and a plurality of continuous unit periods assumed as periods in which heating is not used in the environment A ratio table that defines a ratio of consumption of hot water supply for the remaining unit period to consumption of hot water use for the reference period, with one unit period as a reference period; Storage processing for storing the total consumption of gas actually used in the environment over one year for each unit period, and the total consumption of gas for each unit period stored in the storage processing A gas application decomposition process for decomposing an application, and the gas application decomposition process includes a kitchen application estimation process for estimating a kitchen application consumption amount for each unit period based on information on gas consumption for the specific period; Based on the approximate value of the consumption of kitchen use obtained in the approximate calculation of the use of kitchen, the consumption amount of hot water supply for the specific period is estimated, and the estimated value of consumption of kitchen use, the ratio table, and the two-use decomposition table, Hot water supply usage estimation process for estimating the consumption of hot water supply during non-specific periods other than the specific period based on the above, an approximate value of consumption of hot water supply during the non-specific period obtained by the hot water supply usage estimation process, and the kitchen Based on the estimate of kitchen applications consumption obtained by the developing approximating process, characterized in that it and a heating applications approximating process to estimate the heating applications consumption of the non-specific period.

According to such APPLICATIONS decomposer, not only a single unit period, among the unit period obtained by one year and more divided, continuous is assumed as a period that does not use heating with large seasonal variations Based on information related to gas consumption in a specific period composed of a plurality of unit periods, the amount of kitchen use for each unit period, that is, the year-round use of kitchen use is estimated. Therefore, not only can the seasonal fluctuation factors be excluded, but it is possible not only to estimate the kitchen consumption with high accuracy, but also when there is a gas consumption period that is clearly different from normal daily life, without being disturbed by that period. It is possible to analyze the usage of gas consumption according to the actual situation. In detail, even if there is a long-term absence in a unit period in a non-specific period and energy consumption is extremely low, or even if there is a long-term absence in a unit period belonging to a specific period, the entire specified period Since the consumption for kitchen use is estimated based on this, the influence can be made extremely small. Not only that, but the estimated value of consumption for hot water supply and consumption for heating use will be estimated based on the estimated value of consumption for kitchen use in this way. Even so, it can be broken down into highly relevant consumption in line with the actual situation.

According to the application decomposition instrumentation 置及 beauty applications decomposer of the present invention typically can be analyzed differs gas consumption period exists, the gas consumption in line with the actual application and.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiment are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  The application disassembling apparatus 100 shown in FIG. 1 is an apparatus used for analyzing energy consumption and the like in an environment in which one household is a unit such as a detached house or each dwelling unit of an apartment house. In the present embodiment, the environment is a single-family house that one dwelling unit occupies, but it may be another environment such as a single dwelling unit in a housing complex. In general, in a building such as this embodiment, it is possible to know the total energy amount of each type of energy consumed per month, which is a unit period, but the distribution of how much each energy was consumed for what purpose. It is difficult to know. In view of such a situation, the application decomposition apparatus 100 calculates, based on statistical data or the like, an allocation of how much and how much the known total energy supplied to the building for each unit period is consumed in the building. Can be estimated and estimated. The application decomposition apparatus 100 is particularly preferably used in an environment represented by a building or the like that uses at least electricity and gas as energy sources.

  The application disassembling apparatus 100 includes a computer 110, an input unit 120, and a display unit 130 as an example of output means. The application disassembling apparatus 100 is realized by causing the computer 110 to execute an application disassembling program described below.

  The input unit 120 causes a user of the apparatus to input information and commands using a keyboard or a pointing device such as a mouse. Information and commands may be input from a remote client computer 104 via the network 102 such as the Internet. In this case, the network interface corresponds to the input unit 120.

  The display unit 130 is an output unit that displays various operation screens and information. In addition to a monitor directly connected to the computer 110, the display unit 130 may be a printer as long as it displays information only. Further, when accessing the application disassembling apparatus 100 from a remote location via a network, an operation screen and information can be displayed using a web page.

  The computer 110 has a general configuration, and includes a CPU that performs various processes and operations, a storage medium such as a hard disk that stores programs and data, and a RAM that is an area for executing programs. In the following description, the term “storage unit” means a storage area (file) secured in a storage medium.

  Next, a functional configuration of the application disassembling apparatus 100 will be described. This is almost equal to the configuration of the application decomposition program 200 at the same time.

  As shown in FIG. 1, the application decomposition program 200 includes a consumption amount storage unit 210, an application decomposition unit 216, an integration unit 218, an output unit 220, and a feed water temperature acquisition unit 222.

  The consumption amount storage unit 210 stores the total gas amount, the total power amount, and the kerosene amount consumed in the environment for each unit period. What is stored in the consumption storage unit 210 is to store the consumption amount of each energy such as the actual gas amount, electric power amount, and kerosene amount for each unit period, and the total amount that is not decomposed according to the use for each energy. It is.

  In this embodiment, the total gas consumption, total power consumption, and total kerosene consumption for each unit period are individually calculated for buildings such as houses and offices, and for single dwelling units in buildings if they are apartments such as apartments and apartments. It is assumed that the energy consumption is acquired and stored for each environment where the energy consumption can be measured. In addition, each energy may be input and accumulated by the user for each unit period, or the operator inputs the consumption amount, or the consumption amount collected by the system via the network is automatically input. May be. The unit of consumption is not limited as long as the amount can be specified. For example, kWh (kilowatt hour) may be used for electricity consumption. Moreover, you may convert into another unit by inputting these public charges as consumption.

  The unit period may be an appropriate period for energy measurement. For example, the unit period may be a monthly unit such as one month or two months, and more specifically, the unit period may be one day or one week. good. In the present embodiment, each month such as January, February, March, etc. is adopted as the unit period (hereinafter, the unit period is referred to as “month”).

The application decomposing unit 216 decomposes the total gas amount, total power amount, and total kerosene amount used each month into consumption amounts for each application. The application decomposition unit 216 includes a gas application decomposition unit 300, a power application decomposition unit 400, and a kerosene application decomposition unit 500. The configuration and operation of the application disassembling unit 216 will be described later. In the present embodiment, four applications of “kitchen application”, “hot-water supply application”, “lighting appliance application”, and “heating / cooling application” are prepared as the applications. The total amount is broken down into these four applications. The relationship between each application and actual usage is defined as follows. The heating / cooling application can be further decomposed into a heating application and a cooling application.
Kitchen use: gas stove and other stove equipment used mainly for cooking Hot water supply use: bathroom water heater, kitchen water heater, washroom water heater, etc. Lighting appliances: TV, video, personal computer, washing machine, vacuum cleaner, electronic Range, electronic rice cooker, refrigerator, ventilation fan, lighting equipment, etc. Heating application: electric stove, air conditioner (heating), kotatsu, electric carpet, kerosene stove, etc. Cooling application: air conditioner (cooling), electric fan, etc. In this embodiment, Gas shall be used for kitchen and hot water supply applications, electric power shall be used for lighting household appliances and cooling applications, and one, two or three of gas, electric power and kerosene will be used for heating applications Each supply energy in the general home environment to be taken is disassembled for each use.

  The accumulating unit 218 accumulates the consumption amount decomposed for each application by the application decomposing unit 216 for each application that overlaps a plurality of energies. For example, when heating by gas, heating by electricity, and heating by kerosene are used in combination, heating is overlapped for each energy use, so the energy consumption used for heating is (energy consumption of gas heating (Gh)) + (Energy consumption of heating by electricity (Eh)) + (energy consumption of heating by kerosene (Kh)). In addition, in order to integrate, it is necessary to align the unit of consumption, but the application decomposing unit 216 may align the unit and output it to the integrating unit 218, or the integrating unit 218 converts (converts) the unit. You may accumulate from.

  The output unit 220 outputs the result of integration by the integration unit 218 to the screen, printer, web page, etc. of the client computer 104 via the display unit 130 or the network 102. Also, the result of integration may be recorded and accumulated by outputting it to a recording medium.

  Although the feed water temperature acquisition means 222 will be described later, the feed water temperature or temperature before being heated or cooled by the gas (energy) is acquired. These temperatures may be actually measured by installing a sensor or the like on site, or the temperature of the area may be obtained from data published by the Japan Meteorological Agency. Moreover, the feed water temperature acquisition means 222 may obtain the feed water temperature by converting from the air temperature. As shown in FIG. 2, since a high correlation is recognized between the air temperature and the water temperature, the water supply temperature can be obtained extremely appropriately. In this case, the water supply temperature acquisition means 222 may acquire temperature data announced by the Japan Meteorological Agency via the network 102 such as the Internet.

  In the application disassembling apparatus according to the present embodiment, the user inputs the consumption amount of each energy for one year before the present on the input screen illustrated in FIG. To accumulate. At this time, the energy consumption amount of the current month (the current month in which the calculation is performed and is also referred to as the latest month below) is configured to be input separately on the input screen illustrated in FIG. 3B. Also good. Then, the application decomposing unit 216 calculates each energy and decomposes the total amount for each application, the integrating unit 218 integrates for each application, and the output unit 220 displays the result on the display unit 130 or the like.

  FIG. 4 is a diagram illustrating an example of a screen display of result output, which is output to the display unit 130 and presented to the user. FIG. 4A shows a bar graph accumulated for each unit period (here, monthly). FIG. 4B shows a bar graph in which energy for each application is accumulated throughout the year and energy consumption for each application is accumulated. Further, as shown in FIG. 4C, by displaying the data of the previous year and the data of this year at the same time and displaying them in comparison, it is possible to expect an effect of motivating the user to save energy. Furthermore, as shown in FIG. 4 (d), expecting the effect of motivating users to save energy by evaluating the user's propensity to consume by ranking in comparison with others. Can do.

  In addition to or in place of the result of integration by the integration unit 218, consumption by use (value before integration) for each energy may be output from the output unit 220. In FIG.4 (c), the kind of energy use can be selected, and consumption can be displayed according to the selected energy use. It is important to understand comprehensively, but knowing more detailed propensity to consume is also meaningful for improving life.

  As explained above, by disassembling each month for each use, and by accumulating the consumption of each energy for each use that overlaps multiple energy, homes, offices, living spaces, etc. that use multiple energy It is possible to calculate and present comprehensively the consumption situation for each use of a plurality of energy sources. As a result, the user can comprehensively grasp his or her own propensity to consume, which can be used as an energy saving activity.

[Application decomposition unit 216]
Next, the application disassembling unit 216 will be described. As described above, the application decomposition unit 216 includes the gas application decomposition unit 300, the power application decomposition unit 400, and the kerosene application decomposition unit 500 (FIG. 1).

(Gas application decomposition unit 300)
FIG. 5 is a diagram for explaining the configuration of the gas use decomposition unit 300, and FIGS. 6 and 7 are flowcharts for explaining the operation of the gas use decomposition unit 300.

  The gas use decomposing unit 300 includes a table specifying unit 310 that specifies the ratio of each month for each use, a consumption storage unit 210 that stores the total gas consumption of each month, and each month based on the table specifying unit 310. And a rough estimation unit 320 for decomposing the total gas consumption for each application. The table defining unit 310 includes a standard data creating unit 311 that creates data serving as a basis for calculating standard kitchen usage consumption and hot water supply usage consumption for each month based on statistics or monitoring data, and based on the base data. A two-use decomposition table defining unit 312 that forms a two-use decomposition table that defines the ratio between the consumption amount of kitchen use and the consumption amount of hot water supply for each month, and a gas reference month, and sets the gas reference month And a ratio table defining unit 313 that defines a ratio table that defines the ratio of consumption for hot water supply use.

  The standard data creation unit 311 prepares a typical usage ratio (hot water supply kitchen ratio) between the hot water supply application and the kitchen application based on the statistics, and stores it in the hot water supply kitchen ratio table as shown in FIG. The hot-water supply kitchen ratio is the ratio of the energy of a comprehensive hot-water supply application and a kitchen application in a predetermined energy consumption environment. In the present embodiment, the hot water supply kitchen ratio is determined based on “Household Statistics Statistics Annual Report” “Consumption Matrix for Each Use for Household Use (Kanto) 2005”. Specifically, in this embodiment, among the “lighting / home appliances / others” of the matrix, the city gas and the LPG gas are defined as “kitchen use”, and for hot water supply using electric power, Using efficiency, it is converted to hot water use by gas, and this determines the annual ratio of hot water use and kitchen use.

  The hot water supply kitchen ratio can also be updated every year. In addition to the configuration determined based on the “Household Energy Statistics Annual Report”, it is also possible to derive based on the “resource / energy statistics” statistics of the Agency for Natural Resources and Energy. Furthermore, the hot water supply kitchen ratio is not only determined based on the statistical values disclosed by public institutions as described above, but may be acquired by monitoring (sampling) an actual environment, for example, a plurality of residences.

  Similarly, in the standard data creation unit 311, the average daily gas consumption for hot water use specified based on statistical values (for example, statistical values disclosed by public institutions) (average hot water use gas amount) Prepare. In the present embodiment, the average hot water use gas amount is defined based on the hot water supply load L mode of the “Energy Saving Handbook” of the Building Environment and Energy Saving Organization. Specifically, since the statistical value according to the energy-saving handbook is the hot water supply load for each time zone in the day, the average daily hot water use gas amount is derived by integrating this, and this daily average By integrating the amount of hot water use gas for the number of days in each month, the gas consumption for hot water use in each month is derived. The average hot water use gas amount is not limited to be determined based on statistical values disclosed by public institutions as described above, and may be acquired by monitoring (sampling) an actual general household.

  The hot water supply kitchen ratio and the average daily hot water use gas amount are information prepared in advance by public data and monitoring as described above. The basic data, which is a statistical value for creating the hot water supply kitchen ratio and standard data, can be input by the user, or the basic data of a certain period is input to the application disassembling apparatus 100 as an initial setting. In addition, it is possible to adopt a configuration in which basic data is updated one by one by receiving distribution of update data as appropriate. Hereinafter, a process of forming a dual-use decomposition table using these prepared information will be described. In the following description, the gas consumption that is considered to be normally consumed for kitchen use based on statistical data or the like in the environment to be analyzed by the use decomposition apparatus 100 is referred to as “standard kitchen use consumption”. , “Gk [STD]”. Similarly, the gas consumption that is considered to be consumed as a standard for hot water supply use is referred to as “standard hot water supply use consumption” and is represented by “Gs [STD]”.

  The two-use disassembly table defining unit 312 includes a standard consumption derivation unit 314 and a rate conversion unit 315. As illustrated in FIG. 9, the standard consumption amount deriving unit 314 derives the standard kitchen use consumption and the standard hot water supply use consumption for each month as an example of the standard table 314a. The ratio conversion unit 315 converts the standard kitchen usage consumption and standard hot water supply usage consumption for each month derived by the standard consumption derivation unit 314 into a percentage (percentage), and as illustrated in FIG. A two-use disassembly table 315a is completed.

  The standard consumption derivation unit 314 performs a kitchen process for deriving a standard kitchen use consumption Gk [STD] for each month and a hot water supply process for deriving a standard hot water supply use consumption Gs [STD].

  In the kitchen process, the gas consumption for kitchen use calculated by the standard data creation unit 311 is set to the standard kitchen use consumption Gk [STD] for each month. Therefore, the standard kitchen usage consumption Gk [STD] for each month has the same value. In the kitchen process, the calculated results for each month are stored in the standard table 314a (FIG. 9).

  In the hot water supply process, a standard hot water supply usage amount Gs [STD], which is a standard hot water supply gas consumption amount for each month, is calculated based on the average daily hot water supply gas amount. For example, it may be derived by taking into account the number of days in each month and the number of people in the environment (for example, the number of families) in the average daily hot water gas consumption. For example, while adding up the number of family members in the bathroom, adjusting the amount of hot water from the viewpoint of not adding up the number of people in the hot water bath, or from the viewpoint that children do not use hot water until adults The amount of hot water supply gas consumption in the environment is derived according to the usage mode of the family for general hot water supply applications such as adjustment of the hot water amount. In addition, it is desirable to prepare an average daily hot water supply gas consumption, which is a reference value, depending on the number of family members such as a family of two, a family of three, and a family of four and the ratio of adult children.

Furthermore, in this embodiment, water temperature and equipment efficiency are taken into account in deriving hot water supply gas consumption. Specifically, the average water temperature of the water supply for the month is acquired with reference to the water supply temperature acquisition means 222. As described above, the water supply temperature acquisition unit 222 can derive the water temperature from the air temperature announced by the Japan Meteorological Agency. Then, assuming that the required amount of hot water per day obtained from statistics etc. is Wt, the number of days constituting the unit period is D, the hot water supply temperature is Th, the water supply temperature is Tw, and the equipment efficiency is Co, the standard hot water use consumption Gs for each month [STD] is calculated using the following equation (1). As described above, the necessary amount of hot water for the day can adopt an integrated value of the hot water amount that is adjusted according to the structure of the family for deriving the hot water supply gas consumption amount as described above. It is also possible to adopt a statistical value obtained as a result of monitoring or the like.
Standard hot water consumption consumption Gs [STD] = (Th-Tw) x Wt x D / Co ... Formula (1)

  In the formula (1), even if the amount of hot water is the same, more gas is used if the feed water temperature is lowered. Further, it is shown that the higher the equipment efficiency Co is, the smaller the amount of gas used is.

  Thus, in the hot water supply process, when calculating the standard hot water use usage Gs [STD] for each month based on the statistical value, the process considering the water supply temperature of each month is performed, so the number of days in the month is the same. Even so, the gas consumption in the cold season increases and the gas consumption in the warm season decreases. Thereby, the statistical gas amount for hot water supply according to the actual situation can be calculated with extremely high validity from the daily required hot water amount based on statistics. In addition, a more appropriate result can be obtained by calculating the efficiency of gas equipment installed in a house or the like.

  In the hot water supply process, the calculated results for each month are stored in the standard table 314a (FIG. 9).

Next, along the kitchen process, a standard kitchen usage consumption Gk [STD] defined based on statistics is calculated. Specifically, as shown in the following formula (2), first, the standard hot water supply usage amount Gs [STD] for each month calculated by the hot water supply process is summed to calculate the annual total hot water supply usage amount. Then, multiply the annual total standard hot water use consumption by the hot water supply kitchen ratio K = yRk / yRs, and further divide by the number N of unit periods for one year to obtain the standard kitchen use consumption Gk [STD] for the unit period. . In the present embodiment, since the unit period is the number of months, N = 12 is adopted. Then, the standard kitchen use consumption Gk [STD] is common to each month, and the calculated result of each month is stored in the standard table 314a (FIG. 9).
Standard kitchen usage Gk [STD] = ΣGs [STD] x K / N (2)
The hot water supply kitchen ratio K = yRk / yRs can be calculated based on the hot water supply kitchen ratio table (FIG. 8).

  As shown in FIG. 9, the standard table 314 a that defines the monthly hot water supply usage amount and the standard kitchen usage amount is completed as illustrated in FIG. 9 by the arithmetic processing in each of the kitchen process and the hot water supply process. S101 in FIG. 6). Thereafter, the ratio conversion unit 315 converts these into ratios (percentage) for each month, thereby completing the dual-use decomposition table 315a as illustrated in FIG. 10 (S102). The two-use decomposition table 315a created in this way shows a distribution ratio between general and standard hot water supply use consumption and kitchen use consumption based on statistical data and the like.

  The table defining unit 310 includes a ratio table defining unit 313 that defines the ratio table 316a as illustrated in FIG. 11 based on the standard table 314a calculated by the dual-use decomposition table defining unit 312. . The ratio table 316a shows the ratio of the standard hot water supply usage for each month in the standard table 314a, and the standard hot water usage usage for the gas reference month (the reference month is June in the case of FIG. 11) to be described later. Standard consumption for hot water supply for each month when 1 is set. Of the data in the ratio table 316a, what is required for the following calculation is “heating period” (details of the heating period will be described later. In the present embodiment, the heating period is 1 to May and 10 to 12). Therefore, the data other than the heating period in the ratio table 316a may be omitted as shown in FIG. The ratio table prescribing unit 313 performs a reference month selecting step for determining a gas reference month and a ratio calculating step for calculating a ratio of the standard hot water supply usage for each month based on the gas reference month.

  In the reference month selection step, first, a “non-heating period” that is a specific period is set by the specific period selection means 317. The “non-heating period” is a plurality of continuous unit periods (months) assumed to not use heating in an area where the environment to be analyzed exists. For example, in the case of Kanto, June, August, September is set as the non-heating period. The non-heating period may be set by allowing the user to input a month in which heating is not expected. Note that a month other than the non-heating period is referred to as a “heating period (non-specific period)” as a month in which heating may be used. Next, of the first month or the last month belonging to the non-heating period, the month with the maximum total gas consumption is recognized as the “gas reference month” by the reference month selection unit 316. In the reference month selection step, the consumption amount storage unit 210 is accessed to compare the total gas consumption amounts of the non-heating months that can be candidates for the gas reference month, and the month with the largest total gas consumption amount is selected. It is supposed to be the gas reference month (authorization means). Note that the gas reference month can be appropriately determined in advance in consideration of the local climate as in the non-heating period.

  Further, the remaining part of the non-heating period excluding the gas reference month is set as the “summer period”. For example, in the Kanto region, June is often the “gas reference month” and July, August, and September are often “summer periods”. The “summer period” set in this way is a period in which a tendency specific to summer tends to appear stably in gas consumption for hot water supply.

  After the gas reference month is certified in the reference month selection process, the process proceeds to the ratio calculation process. In the ratio calculation step, with reference to the standard table 314a, the ratio of the standard hot water supply use consumption Gs [STD] of another month to the standard hot water use use consumption Gs [STD] of the month certified as the gas reference month is calculated. calculate. Thereby, the ratio table 316a illustrated in FIG. 11 is completed (S103). The ratio table 316a created in this way indicates the ratio of consumption for hot water supply for each month based on statistical data and the like.

(Approximate gas consumption for each application)
Next, an estimation of gas consumption for each application by the estimation unit 320 will be described. The estimation unit 320 calculates the total gas consumption from the above-described two-use decomposition table 315a and ratio table 316a and the actual total gas consumption for each month stored in the consumption storage unit 210 as the kitchen usage consumption. The calculation which decomposes | disassembles into hot water use consumption and heating use consumption is performed. The estimation unit 320 includes a kitchen usage estimation unit 321, a hot water supply usage estimation unit 322, and a heating usage estimation unit 324. The hot water supply usage approximating unit 322 includes first approximating means 322a, second approximating means 322b, and determining means 322c.

  In the following description, the total gas consumption for m months (m = 1, 2,..., 12) stored in the storage unit 210 is represented by G [m]. For example, the total gas consumption in March is represented as G [3], and the total gas consumption in October is represented as G [10]. In addition, the consumption for kitchen use, consumption for hot water supply, and consumption for heating for m months estimated and approximated by the calculation of the estimation unit 320 are represented by Gk [m], Gs [m], and Gh [m], respectively. . In addition, out of the consumption amount for kitchen use and consumption amount for hot water supply, the value estimated in the first estimation process described later is expressed as Gk1 [m] and Gs1 [m], and the second estimation process described later. The values approximated by are expressed as Gk2 [m] and Gs2 [m]. In addition, the kitchen usage rate and hot water supply usage rate in m month specified in the two-use decomposition table 315a are represented by Rk [m] and Rs [m], respectively. Further, the ratio of m month specified in the ratio table 316a is represented by t [m].

  Further, in the following description, when a specific example of calculation is shown, based on the standard table 314a shown in FIG. 9, the dual-use decomposition table 315a shown in FIG. 10, and the ratio table 316a shown in FIG. It is assumed that the calculation is performed and the first approximate result table of FIG. 12 and the use decomposition result table of FIG. 13 are obtained. The first approximate result table is an intermediate calculation result obtained by the first approximate process described later based on the tables 314a, 315a, and 316a, and the use decomposition result table is based on the tables 314a, 315a, and 316a. It is the result of the final electric power use decomposition | disassembly obtained by this. Here, the non-heating period is set to 6, 7, 8, and September, the summer period is set to 7, 8, and September, and the gas reference month is set to June.

(Estimated consumption for kitchen use)
The kitchen usage estimation unit 321 calculates the average of the summer period based on the total gas consumption for each month belonging to the summer period and the ratio of the kitchen usage for each month belonging to the summer period specified in the two-use decomposition table 315a. Estimate the amount of consumption for kitchen use, and use this approximate value as the approximate value of consumption for kitchen use from January to December. In the present embodiment, as described above, the non-heating period (specific period) is from June to September, the summer period is from July to September, and the heating period (non-specific period) is from January to May. And 10-12 months. First, the kitchen usage estimation unit 321 extracts the total gas consumption of each month of the previous year from the consumption storage unit 210 (S104), and the kitchen usage ratio Rk [7], Rk [8], Rk in the summer period. The average of [9] is calculated as the summer average of the kitchen use ratio, and the average value of the total gas consumption G [7], G [8], G [9] for the summer period is the summer average of the total gas consumption. Calculate as Then, as shown in the following equation (3), the kitchen usage estimation unit 321 multiplies the summer average of the kitchen usage ratio and the summer average of the total gas consumption, thereby calculating the average kitchen usage consumption during the summer period. Approximate (S105) Then, the approximate value is set as the consumption amount Gk [1] to Gk [12] for each month, and is defined as constant annually (S106; first estimation process). According to the calculation of such kitchen use consumption Gk [1] to Gk [12], it is possible to avoid underestimating the kitchen use consumption while suppressing the effects of the use of heating and the long-term absence. .
Gk1 [m] = {(G [7] + G [8] + G [9]) / 3} × {(Rk [7] + Rk [8] + Rk [9]) / 3}; where m = 1-12 ... Formula (3)

  As described above, the consumption for kitchen use is considered to be a substantially constant value throughout the year. This is because the gas used for the so-called gas stove in the kitchen is considered to have no seasonal factors that have a large effect on the overall calculation. Further, since the difference between the water temperature and the cooking temperature is large, it is considered that the influence of the water supply temperature can be ignored in the kitchen.

  In the present embodiment, as described above, the summer period excluding June, which is defined as the gas reference month, is set in the non-heating period, and based on the kitchen use ratio and the total gas consumption in this summer period. However, the monthly consumption of kitchen use Gk1 [1] to Gk1 [12] is estimated, but based on the ratio of total use of kitchen and the total consumption of gas for the entire non-heating period including the gas reference month Kitchen usage consumption Gk1 [1] to Gk1 [12] may be estimated. In addition, in the non-heating period, each month's kitchen is based on the month's kitchen usage ratio and the total gas consumption, excluding one or both of the month with the lowest and the highest month. The usage consumption Gk1 [1] to Gk1 [12] may be estimated. In this way, if the kitchen use consumption Gk1 [1] to Gk1 [12] for each month is estimated based on the kitchen use ratio and the total gas consumption of at least some months belonging to the non-heating period, It is possible to appropriately select which month of the heating period to use the kitchen usage ratio and the total gas consumption.

(Approximate processing for consumption of hot water supply)
The hot water supply use estimation unit 322 belongs to a non-heating period hot water supply use consumption estimation process for estimating the monthly hot water use application consumption belonging to the non-heating period (specific period), and a heating period (non-specific period) other than the non-heating period. A heating period hot water supply usage consumption estimation process for estimating the monthly hot water supply usage consumption is performed. The heating period hot water supply usage consumption estimation process includes a first estimation process by the first estimation unit 322a, a second estimation process by the second estimation unit 322b, and a determination process by the determination unit 322c.

(First estimation process)
As shown in the following formula (4), the first approximate means 322a of the hot water supply use estimation unit 322 is configured to calculate the total gas consumption G [6] to G [9] in each month (June to September) belonging to the non-heating period. Then, the value obtained by subtracting the kitchen usage consumption Gk1 [6] to Gk1 [9] estimated by the kitchen usage estimation unit 321 is calculated as the approximate value of the hot water usage usage Gs1 [6] to Gs1 [9]. (S107: Non-heating period hot water supply usage consumption estimation process).
Gs1 [m] = G [m] -Gk1 [m]; However, m = 6 to 9 Equation (4) (corresponding to the following period)

Furthermore, the 1st rough calculation means 322a is the ratio t [1] -t [5], t [10] prescribed | regulated to the ratio table 316a of each month (1-May and October-December) which belongs to a heating period. Based on ~ t [12], the consumption for hot water supply in each month belonging to the heating period is estimated. Specifically, as shown in the following formula (5), the total gas consumption G [6] of the gas reference month (June) is multiplied by the hot water supply usage ratio Rs [6] of the dual-use decomposition table 315a. Estimate hot water usage consumption Gs1 [6] for the base month. Then, as shown in the following equation (3), by multiplying the approximate value of the hot water consumption consumption Gs1 [6] for the gas reference month by the ratio t [m] of the ratio table 316a, the hot water supply usage for each month of the heating period The consumption Gs1 [m] is estimated (S108).
Gs1 [m] = Gs1 [6] × t [m]; provided that m = 1 to 5 or 7 to 12 Formula (5)

  As described above, by using the ratio table 316a defined in advance, it is possible to easily obtain an approximate value of consumption amount for hot water supply for each month.

  Gk1 [1] to Gk1 [12] and Gs1 [1] to Gs1 [12] are obtained by the first approximate processing described above, and the first approximate result table shown in FIG. 12 is created.

(Second approximate processing)
As shown in the following formulas (6) and (7), the second approximating means 322b of the hot water supply usage approximating unit 322 calculates the total gas consumption G [m] for each month in the heating period in the dual usage decomposition table 315a. By distributing to the ratio of the month (hot water usage rate Rs [m], kitchen usage rate Rk [m]), each usage of hot water usage Gs2 [m] and kitchen usage Gk2 [m] Estimate consumption. That is, in the second rough calculation means 322b, it is assumed that the heating use is not included in the total gas consumption G [m] (that is, Gh [m] = 0), and the warm use The total gas consumption G [m] is decomposed only for two uses, ie, a kitchen use and a hot water supply use (S109).
Gs2 [m] = G [m] × Rs [m]; where m = 1 to 5 or 7 to 12 (6)
Gk2 [m] = G [m] × Rk [m]; provided that m = 1 to 5 or 7 to 12 (7)

(Judgment process)
In addition, for each month of the heating period, the determination unit 322c calculates the total gas consumption G [m] for each month and the total Gk1 [m] + of the estimated values for each use of the unit period by the first estimation unit 322a. When Gs1 [m] is compared (S120) and the total gas consumption G [m] is larger, the result of the estimation by the first estimation means 322a is used as the gas Gk1 [m], Gs1 [m]. Adopted as a result of application decomposition (S121). On the other hand, when the total value Gk1 [m] + Gs1 [m] of the first approximating means 322a is made larger, the approximate results Gk2 [m] and Gs2 [m] by the second approximating means 322b are used as gas applications. Adopted as a result of the decomposition (S122).

  That is, the estimation of each use by the first estimating means 322a is to calculate each use of each month of the heating period independently based on the total gas consumption of the gas reference month. In addition, it is possible to roughly estimate the usage of the target environment, and to estimate the usage of each target based on the consumption trend of the total gas consumption of the estimated target environment. However, for example, if there is a situation of unusual usage such as long-term absence of a user in a certain month, or heating is specified as having a gas application, it is actually in the month corresponding to early spring or autumn There are cases where almost no heating is used. In these months, it is conceivable that the total gas consumption will be less than that assumed when the first approximate means 322a is used for the estimation. Then, there is a possibility that the sum of the approximate values obtained by the first approximate means 322a becomes larger than the total gas consumption G [m] for the month, which is different from the actual situation.

  On the other hand, the second approximating means 322b is a preliminary approximating means that compensates for the deficiencies of the first approximating means 322a as described above, and only decomposes the total gas consumption into two applications. The value is equal to the total power.

  Therefore, the judgment means 322c compares the total gas consumption with the total of the first approximate values, and when the total gas consumption is larger, the approximate values of the first approximate means 322a are adopted. (S121) When the first approximate value is larger, each approximate value by the second approximate means 322b is adopted (S122). That is, when there is a month when the amount of gas used is extremely small, it is assumed that no gas is used for heating, and all the gas is used for the kitchen and hot water supply. Thereby, it is possible to prevent the calculated result from exceeding the actually measured value and obtain a more appropriate result.

For example, referring to the first approximate value shown in FIG. 12, in May, the total gas consumption G [m] = 29.4 m ³ (about 1323 MJ), whereas Gk1 [5] + Gs1 [5 ] = 1352.2MJ and Gk1 [5] + Gs1 [5]> G [5]. And, if the heating consumption Gh [5], which will be described later, is calculated as it is, a negative value such as Gh [5] =-29.4MJ is obtained, which is not suitable for the actual situation. Therefore, as shown in FIG. 13, the consumption for kitchen use and consumption for hot water supply in May are Gk2 [5] = 254.4MJ and Gs2 [5] = 1068.6 obtained in the second approximate processing, respectively. MJ is adopted as a result of gas application decomposition. On the other hand, for months other than May in the heating period, Gk1 [m] + Gs1 [m] <G [m], so Gk1 [m] and Gs1 [m] obtained in the first rough calculation process Is adopted as a result of gas use decomposition.

(Approximate processing for heating use)
In the heating usage estimation unit 324, when the estimation value of the first estimation unit 322a is adopted by the determination unit 322c, it is assumed that the remainder with respect to the total gas consumption is used as the heating usage as shown in the following equation (8). The In addition, an approximate value of the heating use consumption Gh [m] is derived (S125).
Gh [m] = G [m]-(Gk1 [m] + Gs1 [m]); provided that m = 1 to 5 or 10 to 12 (8)
Also, during non-heating periods, it is assumed that heating is not used,
Gh [m] = 0; where m = 6 to 9 (9)
It is.

  As described above, the result of the gas use decomposition as shown in the use decomposition result table of FIG. 13 is obtained.

  The gas use decomposing unit 300 outputs the calculated gas consumption for each use to the integrating unit 218.

  According to the above configuration, if the total gas consumption of each month is recorded throughout the year, the total gas consumption of each month can be broken down into uses for kitchen use, hot water supply use, and heating use. Then, in the estimation of the heating period, by having the two approximate routes by the first approximate means 322a and the second approximate means 322b, even if there is a different gas consumption month than usual, the energy in accordance with the actual situation The usage of consumption can be analyzed. For example, even if the total gas consumption is extremely small because a warm day continues in a unit period (for example, March) in the heating period and heating is not used, the influence can be extremely reduced.

  The table defining unit 310 includes table updating means 330 that updates the two-use decomposition table 315a and the ratio table 316a each time the user inputs the total gas consumption of the latest month to the consumption storage unit 210.

  The standard table 314a, which is the base for defining the two-use decomposition table 315a and the ratio table 316a, shows the standard for each use in the past year including the latest month as described above. Since the standard value is calculated by taking the factor into account, the same numerical value cannot be adopted for one year. In addition, in the above, since each usage amount of the hot water usage, kitchen usage, and heating usage for each month is calculated based on the standard hot water usage, the usage of each of these usages is changed as long as the hot water usage usage of the latest month changes. The approximate amount also changes.

  Therefore, as shown in FIG. 7, when the table updating unit 330 confirms that the total gas usage amount of the latest month has been input to the consumption storage unit 210 (S21), the table setting unit 310 is set to one year. The period of the current month is updated and set in the past year including the latest month, and the water supply temperature acquisition unit 222 acquires the water temperature of the latest month, and after updating these conditions, the table defining unit 310 re-reads the standard table 314a. It is calculated (S22). Then, based on the updated standard table 314a, the two-use decomposition table 315a and the ratio table 316a are updated (S23, S24). As a result, the usage decomposition of the total gas consumption of the latest month is shown in a state in accordance with the actual situation of the latest month, and the decomposition accuracy is improved.

(Power application decomposition unit 400)
FIG. 14 is a diagram for explaining the configuration of the power application decomposing unit 400, and FIG. 15 is a flowchart for explaining the operation of the power use decomposing unit 400. In FIG. 14, arrows indicate the flow of data.

  The power use decomposing unit 400 includes an intermediate period minimum electricity quantity acquiring unit 402 and an electrolysis calculating unit 404. The electrolysis calculation unit 404 further includes an electrical quantity estimation unit 414 for lighting / home appliances, an electrical quantity estimation unit 416 for cooling, and an electrical quantity estimation unit 418 for heating.

  The minimum amount of electricity acquisition unit 402 first identifies the interim period (S402). The intermediate period is a period between summer and winter, and can be appropriately determined in consideration of the local climate. Here, the months next to each other in the summer season described above are regarded as intermediate periods. That is, in this embodiment, since the summer period was July, August, and September, June and October are intermediate periods. Then, the intermediate period minimum electricity amount acquisition unit 402 refers to the consumption amount storage unit 210 and acquires the lowest power consumption (intermediate period minimum electricity amount E (Mmin)) in the intermediate period (June and October). The month indicating the minimum power consumption is recognized as the “power reference month”. For example, in the Kanto region, June is often the power reference month.

As shown in the following formula (10), the lighting / appliances application estimation unit 414 directly uses the intermediate period minimum electricity amount E (Mmin) acquired by the intermediate period minimum electricity amount acquisition unit 402 for each unit period. The estimated amount of electricity Ea for lighting / home appliances (estimated amount of electricity for lighting / home appliances) is defined (S406). In the example shown in FIG. 16, the power consumption in June of 266.4 kWh is compared with the power consumption in October of 285.8 kWh, and the smaller power consumption of 266.4 kWh (959.0 MJ) in June is the lowest mid-term electricity consumption E. (Mmin). First, 959.0MJ is set as the estimated amount of electricity Ea for lighting and home appliances in January to December.
Estimated amount of electricity for lighting and home appliances Ea = Mid-term minimum amount of electricity E (Mmin) ... Formula (10)

  This is because the amount of electricity for lighting and home appliances can be assumed to be constant throughout the year.

  Here, the reason why the month showing the lowest power consumption amount in the middle period is selected as the electric reference month in order to exclude the amount of power consumed for air conditioning by excluding the summer and winter seasons. On the other hand, the reason why the electricity reference month was not set as the month indicating the lowest annual power consumption is because the minimum electric power consumption would be extremely low if there was a long absence somewhere in the year. This is because the estimated amount of electricity for lighting and home appliances may be estimated low throughout the year.

Next, the cooling electricity amount estimation unit 416 compares the power consumption amount E for each month in the specific period with the intermediate period minimum power amount E (Mmin) defined above (S408). Then, as shown in the following equation (11), when the intermediate period minimum power amount is larger, a correction for replacing the estimated value Ea for lighting / home appliance use with the power consumption amount E is performed (S410). In the example shown in FIG. 16, only in February data, the amount of electricity used is 959.0 MJ, which is the middle-term minimum electricity amount, which is larger than 261.1 kWh (940.0 MJ). Therefore, the estimated value Ea for lighting / home appliance use in February is replaced with the actual power consumption E (940.0MJ).
Estimated amount of electricity for lighting and home appliances Ea = Actual amount of power consumption E ... Equation (11)

  That is, when there is a month when the amount of power consumption is extremely small, it is assumed that there is no electricity used for air conditioning, and all electricity is used for lighting, home appliances and the like. Moreover, it correct | amends so that the electrical quantity Ea for illuminations and household appliances may become small according to total electric power consumption. Thereby, it is possible to prevent the estimated result from exceeding the actual power consumption, and to obtain a more appropriate result.

As shown in the following formula (12), the cooling electricity quantity estimation unit 416 approximates the lighting / home appliance usage from the total electric energy E [m] for the unit period belonging to the non-heating period (for example, from June to September). By subtracting the value Ea [m], an approximate value Ec [m] for cooling use for each unit period is calculated (S412).
Estimated quantity of electricity for cooling Ec [m] = E [m] -Ea [m]; where m = 6 to 9 (12)

  As described above, the non-heating period is a period in which heating is assumed not to be used. For example, in the Kanto region, it can be set from June to September.

As shown in the following formula (13), the heating electricity amount estimation unit 418 performs illumination from the total power consumption E [m] for the unit periods (1 to May and 10 to 12 months) other than the non-heating period. -The approximate value Eh [m] for the heating application for each unit period is calculated by subtracting the approximate value Ea [m] for the home appliance use (S414).
Estimated amount of electricity for heating Eh [m] = E [m] -Ea [m]; provided that m = 1 to 5 or 10 to 12 (13)

  The power usage decomposing unit 400 outputs the calculated amount of electricity for each usage to the integrating unit 218.

(Kerosene application decomposition unit 500)
Further, in this embodiment, gas and electric power cover the energy required for hot water supply, kitchen, lighting appliances, and cooling, and as such, the use of kerosene is only used for heating assistance, and the kerosene Is not expected to be used for hot water supply. Therefore, in the present embodiment, in the kerosene application decomposition process shown in FIG. 17, the actual amount K of kerosene can be estimated as it is as the heating kerosene amount Kh. Therefore, the kerosene usage decomposition unit 500 refers to the consumption amount storage unit 210, and uses the kerosene usage amount K input by the user as it is for heating heating of kerosene as shown in the following equation (14) (S31).
Kerosene amount for heating Kh = Kerosene consumption amount K ... Formula (14)

  In this case, it is not necessary to consider a non-heating period or an intermediate period. The kerosene usage decomposition unit 500 outputs the calculated kerosene amount for each usage to the integrating unit 218.

  Then, the integration unit 218 integrates the outputs of the gas application decomposition unit 300, the power application decomposition unit 400, and the kerosene application decomposition unit 500 for each application. From the output unit, the data is output to a display unit and presented to the user.

  Then, the effect by the application decomposition | disassembly apparatus 100 mentioned above, the application decomposition | disassembly program 200 performed with the said apparatus 100, and the application decomposition | disassembly method performed with the said apparatus 100 is demonstrated.

  According to the application decomposing apparatus 100, not only a single month but also a kitchen use consumption for each month based on information on gas consumption in a non-heating period assumed as a period in which heating with a large seasonal variation is not used. , Kitchen consumption for the year is estimated. Therefore, not only can the seasonal fluctuation factors be excluded, but it is possible not only to estimate the kitchen consumption with high accuracy, but also when there is a gas consumption period that is clearly different from normal daily life, without being disturbed by that period. It is possible to analyze the usage of gas consumption according to the actual situation.

  In detail, even if there is a long-term absence in the month of the heating period (for example, January) and energy consumption is extremely low, or even if there is a long-term absence in the month belonging to the non-heating period, Since the amount of consumption for kitchen use is estimated based on the information of the entire heating period, the influence can be extremely reduced. Not only that, but the estimated value of consumption for hot water supply and consumption for heating use will be estimated based on the estimated value of consumption for kitchen use in this way. Even so, it can be broken down into highly relevant consumption in line with the actual situation.

  In addition, according to the application disassembling apparatus 100, the first estimation means 322a that anticipates seasonal fluctuations in the consumption amount of hot water supply for gas in the ratio table 316a in advance and approximates the consumption amount of hot water supply for each month based on the ratio table 316a. It has. Therefore, the gas consumption can be accurately decomposed in a hot water supply application that has a large range of change in consumption during the year and often reflects the life stage and preference of each household. On the other hand, simply decomposing each month's gas consumption based on the ratio table 316a may produce a result that is significantly different from the actual situation when the consumption of hot water in the target household is very small compared to the approximate value. .

  Therefore, the application disassembling apparatus 100 includes second approximating means 322b that approximates these uses by using a two-use disassembly table 315a that preliminarily defines the ratio of consumption of hot water supply and consumption of kitchen use. The first disassembling means 322a and the second approximating means 322b are provided with a determining means 322c that makes a determination by comparing the weights, and by using the most appropriate estimated value by the determining means 322c, the use disassembly that avoids the deviation from the actual situation It is something that can be done. Therefore, according to the apparatus 100, the program 200, and the application decomposition method, it is possible to perform analysis to analyze the use of energy according to the actual situation in an environment where gas is supplied as an energy source.

  Further, since the total gas consumption G [m] is an actual measurement value, it is determined that the approximate value of the first approximating means 322a that exceeds the actual measurement value is different from the actual situation. On the other hand, since the second approximate means 322b decomposes the total gas consumption based on the two-use decomposition table 315a, the sum of the approximate values for each application by the second approximate means 322b is the total gas consumption G [m]. As such, it will not exceed the total gas consumption G [m]. As described above, according to the determination criteria in the above-described determination means 322c, by using the approximate value by the second approximate means 322b only when the approximate value of the first approximate means 322a is clearly different from the actual situation, In general, it is possible to flexibly cope with a situation in which consistency cannot be achieved only with the ratio table 316a, such as the absence of a temporary period or a change in gas consumption pattern due to a change in living conditions.

  The first rough calculation means 322a multiplies the total gas consumption G [m] by the hot water supply usage rate Rs [6] of the reference month (June in this case) specified in the dual-use decomposition table 315a. Of hot water use consumption Gs [6] of hot water supply, and by multiplying the approximate value Gs [6] by the ratio t [m] defined in the ratio table 316a, the consumption amount of hot water use Gs [m] for each reference month Is to be estimated. Since the seasonal variation is expected in the ratio table 316a in advance, by multiplying the approximate value of the consumption amount for hot water supply in the base month by the ratio in the ratio table 316a, the consumption amount for hot water supply in each month Gs [m] It is possible to incorporate the effects of fluctuations.

  Moreover, the 1st estimation means 322a approximates the kitchen use consumption Gk [m] of the said month by applying the average kitchen use consumption of a non-heating period to each month. The non-heating period is a period in which heating is not used, and it is considered that the seasonal variation factor is the least factored in. For applications without seasonal variation, the proportion of the non-heating period should be adopted as it is in other months. Is considered preferable. In addition, it is known that the consumption for kitchen use is relatively small for the total gas consumption. For this reason, even if the value obtained based on the information on the non-heating period is applied to each month for kitchen use, there will be no significant flaws with the actual situation, and the calculation will be simplified. It can be done.

  Further, the second approximate means 322b distributes the total gas consumption G [m] for each month to the ratios Rk [m] and Rs [m] for each month specified in the two-use decomposition table 315a. The consumption Gk [m] and Gs [m] are estimated. In the two-use decomposition table 315a, the ratio of consumption of each use is defined by the relative relationship between the hot-water supply use and the kitchen use in each month, and based on the ratio, the total gas consumption is determined as the hot-water use use, the kitchen. Even if the total gas consumption suddenly decreases due to the absence of a certain temporary period, at least the total gas consumption G [m] can be decomposed into these two applications. It is also possible to cope with changes in gas consumption patterns due to changes in living conditions.

  Moreover, the heating usage estimation unit 324 subtracts the sum of Gk [m] and Gs [m] adopted according to the determination result of the determination means 322c from the total gas consumption G [m] for each month. Estimated as consumption Gh [m]. In this way, after appropriately determining the consumption for kitchen use with little seasonal variation and the consumption for hot water supply that requires some seasonal variation, estimate the consumption for heating use with the largest fluctuation in annual power consumption. The heating consumption can be estimated appropriately.

  Further, the reference month selecting unit 316 recognizes the month having the largest total gas consumption G [m] as the reference month when there are a plurality of gas reference month candidates in the non-heating period. As a result, the month in which the seasonal variation factor of the heating is eliminated as much as possible becomes the reference month, and the consumption of the two uses other than the heating use can be estimated more appropriately.

  In addition, the application decomposition unit 216 can acquire the temperature of the water supply supplied to the building in each month, and the two-use decomposition table 315a based on the supply water temperature acquired by the supply water temperature acquisition unit 222. The hot water usage ratio Rs [m] is calculated. The power consumption in hot water supply is mainly consumed by heating tap water. The power consumption varies depending on the set temperature and the amount of hot water supply, but the power consumption varies depending on the water temperature of the tap water. According to the above configuration, the temperature of the water supply (supply water temperature) is acquired by the supply water temperature acquisition means 222, and each application is calculated by the two-use decomposition table 315a using the supply water temperature. That is, by adding the temperature of the hot water supply as a factor for determining the ratio of the hot water supply application to the rough estimate of the hot water supply application, the accuracy of the ratio for each unit period of the hot water use in the two-use decomposition table 315a is further increased, and consequently the consumption of the kitchen application Can be optimized.

  Moreover, the water supply temperature acquisition means 222 estimates the water supply temperature based on the temperature of the area where the building exists. Thereby, simplification of the said water supply temperature calculation can be aimed at by estimating the water supply temperature which is difficult to measure in a building from air temperature.

  In addition, the application decomposing unit 216 removes the oldest month data in accordance with the input of the total gas consumption for the new month, adds the new month data, and removes the oldest month data, Table updating means 330 is provided for updating the ratios of the decomposition table 315a and the ratio table 316a. As described above, there are cases where the use of each month is disassembled, including those that include seasonal fluctuation factors, and therefore there is at least one month for disassembling the use of the total gas consumption of one month. And the two-use disassembly table 315a and the ratio table 316a for a period of one year including the reference month are required. According to the above configuration, when the total gas consumption of the latest month is decomposed for use, the two-use decomposition table 315a and the ratio table 316a are updated in the latest one year period including the month. The actual situation such as the latest water supply temperature can be reflected in each table construction, and each table can be created appropriately.

  Furthermore, the application decomposition apparatus 100 includes a display unit 130 that displays only the result of the application decomposition of the total gas consumption in the latest month of the month. As described above, the table for the past year including the month can be updated, so that the usage decomposition for the past year can be reconstructed. However, what users want to confirm most is the usage in the latest month. It is the result of decomposition. Therefore, by providing the display unit 130 described above, it is possible to confirm the result of use decomposition in the latest month that the user wants to confirm most. Alternatively, the visibility of the user can be improved by hiding the result of the application decomposition for each month over the past year that is not necessary for the user to be displayed.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention.
