Description

  The present invention relates to a Q value measurement system and a Q value measurement method for actually measuring a heat loss coefficient (Q value) that is a thermal performance index value of a building in an actual building.

Conventionally, it has been pointed out that it is important to promote energy saving of buildings as one of the measures to prevent global warming, and heat insulation of houses has become one of the basic technologies for building buildings. Insulation of houses in Japan has been promoted as a national policy, with the establishment of energy-saving standards in 1980, except in cold regions.
In addition, it is positioned as a necessary performance for housing in laws and public systems such as the Basic Act on Housing and Living and the housing performance display system.

On the other hand, when evaluating and inspecting the heat insulation performance, desk evaluation of calculating and evaluating a heat transmissibility and a heat loss coefficient is used as the only method in practice (see, for example, Patent Document 1).
Although the method itself for inspecting a completed building was proposed over 30 years ago (for example, see Non-Patent Document 1), the thermal insulation of the building may not actually permeate. I don't ask for a value.
Japanese Patent Laid-Open No. 2002-4403 Yo Matsuo and Heizo Saito, “Estimation of Thermal Characteristics of Houses Based on Field Measurements”, Architectural Institute of Japan, Environmental Engineering, No. 3, pp. 13-18, 1981

The above-mentioned Q value is a typical thermal performance index of a building, and the government's housing performance display system uses a heat loss coefficient (hereinafter referred to as a design Q value) calculated based on design books. It is considered good to judge the grade.
However, it has been found that the heat insulation performance of a building is not determined only by the performance and thickness of the heat insulating material, but also depends on the construction method, construction status, airtight performance, and ventilation rate.
Therefore, since the actual Q value of the building after construction cannot be measured with the design Q value, if the measured Q value in the building after construction can be obtained, it is more accurate by using it together with the design Q value. It can be used as a high thermal performance index.

Further, in order to measure the Q value at the site, it is necessary to consider the inside of the building as one space, and it is necessary to measure the Q value with the temperatures of a plurality of rooms being substantially the same.

And temperature data corresponding to the thermometer identification information is read from the internal storage unit at every measurement period of the Q value.

  In the Q value measurement system of the present invention, the Q value measurement processing unit transmits the control value of the heat generation amount of the heater to the measurement unit control unit together with the identification information of the measurement unit, and the measurement The unit control unit sets the input control value in an internal storage unit, and transmits the control value to each of the measurement units in association with the identification information.

Here, the method of measuring the heat loss coefficient is to measure the building as a single room, so the doors of each room are opened, and the doors of furniture and shelves facing the outer wall are opened, so that heat energy is given to each room. A heater that dissipates the heat energy and heat energy that is uniformly diffused inside the room is arranged, and the heat energy is discharged from the heater to keep the temperature inside the building constant.

Hereinafter, a Q-value measuring system 1 according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a Q value measurement system 1 according to the embodiment.
In this figure, the Q value measurement system 1 of this embodiment includes a Q value measurement processing unit 10, a measurement unit control unit 11, a temperature data collection unit 12, measurement units 20, 21,..., An outside thermometer 221, an indoor thermometer. 311, 312, 313, 314,..., A SAT thermometer 220.
The measurement units 20, 21,... Are arranged in each room (including a corridor and a staircase, etc.) inside the building 500, and there are a plurality (for example, five), but FIG. Only 21 is described. The configuration of each measurement unit is the same.
In addition, the Q value measurement processing unit 10, the measurement unit control unit 11, and the temperature data collection unit 12 are also arranged at any location inside the building 500, and are always outlets described later provided in each measurement unit (20, 21). The power supply that operates from

The measurement unit 20 includes a heat control unit 201, heaters 202 and 203, and fans 204 and 205.
Similarly, the measurement unit 21 includes a heat control unit 211, heaters 212 and 213, and fans 214 and 215.
The heaters 202, 203, 212 and 213 take into account the outlet capacity of each room. For example, in the case of a type in which the heat generation amount is manually switched, the maximum heat generation amount is 800 W (the heat generation amount can be switched between 400 W and 800 W) or the maximum heat generation. A sheathed heater having an amount of 600 W (200 W, 400 W, 600 W heat generation amount can be switched) is used. In each measurement unit, the heating value of each heater is used in a combination of 800 W and 600 W, or an arbitrary combination such as 400 W and 200 W. In addition, the heaters 202, 203, 212, and 213 may be of a type that can be adjusted stepwise (for example, 50 W each) by a power regulator in the measurement unit (20, 21). Any of the above-mentioned types of heaters is provided with a blower section using a fan for blowing air inside.
Here, as a control method of each heater, a method of directly controlling the amount of heat generated by a changeover switch provided in the heater itself and a control signal from the Q value measurement processing unit 10 in the measurement unit (20, 21). There is a method of controlling the output of each heater by providing a power regulator for controlling the amount of heat generated by the heater. When directly controlling the amount of heat generated by the changeover switch provided on the heater itself, the amount of heat generated by each heater cannot be controlled remotely in real time. However, it is necessary to provide the function of the power regulator in the measurement unit. The cost of the entire system can be reduced.
However, in this embodiment, in order to improve the accuracy of measurement, each of the power regulators provided in the measurement unit can control the amount of heat generated by each heater by the Q value measurement processing unit 10 by radio in real time. A method of adjusting the amount of heat generated by the heater will be described, and the following method will be described using the power regulator in the measurement unit.
In the case of the method of controlling the output of the power regulator in the measurement unit by the Q value measurement processing unit 10, for example, as described above, two 700 W heaters 212 and 213 are used for one measurement unit 21. Connect and use. At this time, the Q value measurement processing unit 10 can adjust the heat generation amount of each heater 212, 213 by a unit heat generation amount (for example, 50 W unit) set in a stepwise manner.
The heat control unit 201 controls the amount of heat generated by each of the heaters 202 and 203 at the unit heat value in the range of 0 to the maximum heat value.
Further, the heat control unit 201 obtains a heat generation amount from a total consumption current of the heaters 202 and 203, the fans 204 and 205, and the internal circuit in the measurement unit 20 in a preset time unit. 11 to send.
Similarly, the heat controller 211 controls the amount of heat generated by each of the heaters 212 and 213 at the unit heat value in the range of 0 to the maximum heat value.
Further, the heat control unit 211 obtains the heat generation amount from the total consumption current of the heaters 212 and 213, the fans 214 and 215, and the internal circuit in the measurement unit 21 in a preset time unit, and the measurement unit control unit 11 to send.

The fans 204 and 205 are disposed in the same and adjacent rooms as the corresponding measurement units 20, and agitate the air in each room so that the heat energy emitted from the heaters 202 and 203 circulates throughout the room. Accordingly, the fan 205 needs to be disposed at a position where the indoor air distribution is efficiently circulated and the temperature distribution in the room is made as uniform as possible, corresponding to the position where the heat energy released by the heaters 202 and 203 is stirred. is there. For this reason, for example, when a room to be arranged is small, it is assumed that one fan, for example, a fan 205 is used, and this one fan 205 efficiently equalizes the indoor temperature. And the air blowing intensity can be adjusted in a plurality of stages. In addition, the heaters 202 and 203 are provided with two fan sockets branched from the power supply of the blower provided in the heaters 202 and 203.
Similarly, the fans 214 and 215 are arranged in the same and adjacent rooms as the corresponding measurement units 21, and agitate the air inside each room so that the heat energy released by the heaters 212 and 213 circulates throughout the room. To do. Therefore, the fan 215 needs to be disposed at a position where the indoor air distribution is efficiently circulated and the indoor temperature distribution is made as uniform as possible, corresponding to the position where the heat energy released by the heaters 212 and 213 is stirred. is there. For this reason, in order for one fan, for example, the fan 215, to uniformly equalize the indoor temperature, the fan 215 has a swing function, and the air blowing intensity can be adjusted in a plurality of stages. In addition, the heaters 212 and 213 are provided with two fan sockets branched from the power supply of the blower provided in the heaters 212 and 213.
The measurement units 20 and 21 are not controlled by the Q-value measurement processing unit 10, the measurement unit control unit 11, and the like, and are provided with a constant outlet that always supplies power as long as the power supply is turned on. ing. This constant outlet indicates an outlet that is constantly supplied with power without being controlled by the measurement unit control unit 11, and cannot be stopped during the measurement period in which the Q value is measured (for example, a refrigerator, video, etc.). , Telephone, FAX, etc.), and the power supplied to these home appliances is measured by the measurement unit, and the measurement unit adds the power supplied from the regular outlet to the power used by itself. The total value is used as the power consumption of the entire measurement unit. As already described, the Q value measurement processing unit 10, the measurement unit control unit 11, and the temperature data collection unit 12 are also supplied with power from the above-described outlet.

The measurement unit controller 11 transmits / receives data to / from each measurement unit by wireless communication, and the amount of heat generated by each heater currently used for Q value measurement is set. Is transmitted to the heat control unit 201 of the measurement unit 20 and the heat control unit 211 of the measurement unit 21 to control the amount of heat generated by the heater in each measurement unit.
The measurement unit controller 11 measures the amount of heat generated from the total current consumption of the heaters 202 and 203, the fans 204 and 205, and the internal circuit of the measurement unit measured by the measurement unit 20, and is measured by the measurement unit 21. The heaters 212 and 213, the fans 214 and 215, and the total heat consumption (including the stirring unit inside the heater) of the measurement unit internal circuit are read and associated with unit identification information for identifying each measurement unit. Thus, the data is written and stored in the storage unit 112 in a time series at every fixed period (for example, 1 minute) for measuring the calorific value. That is, in each measurement unit, not only the amount of heat generated corresponding to the control value of each heater, but also the heat generated by the fan and the internal circuit is used as the amount of heat generated by the measurement unit to measure the actual Q value to be described later. The amount of heat generated in each room can be accurately used to calculate the measured Q value.

Before measurement, cover all holes that connect to the outside air, such as a ventilation fan, ventilation intake / exhaust port, and drainage port, with a tape. To fully open.

  Next, the processing of the actual measurement of the indoor and outdoor temperatures and the collection of temperature data are started. First, a running operation before actual measurement is performed in a state where only the fan is driven without driving the heater. This run-up operation is performed for, for example, 6 hours or more during a preset run-up operation period, and after this run-up operation, the heater is driven as an actual measurement, and temperature measurement is performed for 4 days or more after starting heating (step S8). ). At this time, the fan is always driven during the measurement period, and the heated air is circulated by stirring the air in the room to make the temperature of the room uniform, and thereby the temperature of the entire room, that is, the temperature in the building. Make it uniform. The measurement unit obtains the power consumption of the fan from the voltage and current and transmits it to the measurement unit controller 11.

  Then, when the run-up operation period ends, that is, the measurement unit control unit 11 counts the elapsed time from the start of the run-up operation by an internal timer, and detects that the count result exceeds the preset run-up operation period. Then, the drive of each heater of each measurement unit 20 and 21 is started, the power consumption of each heater and each fan is calculated | required from a voltage and an electric current, and it transmits with respect to a measurement unit control part (step S9).

  Next, the Q value measurement processing unit 10 receives the SAT temperature of the SAT thermometer 220 and the external temperature data of the outside air thermometer 221 from the temperature data collecting unit 12 at every measurement cycle (for example, every 10 minutes) for measuring the Q value. In order to calculate the measured Q value by reading the temperature data of the indoor thermometers 311 to 314,... And reading the power consumption (heat generation amount) of each unit of each heater and each fan from each measurement unit 20 and 21. Are collected (step S10).

When the data for calculating the actual Q value is collected, the Q value measurement processing unit 10 uses the temperature data of the SAT temperature, the external temperature, and the room temperature, and the power consumption (heat generation amount) of each heater and each fan. The measured Q value is calculated and identified in real time, and the identification result is transmitted to the external device or displayed on the display unit (step S11).
Then, the Q value measurement processing unit 10 detects whether or not the preset measurement period has ended, and if the measurement period has not ended, the process proceeds to step S10, and the Q value measurement period has ended. In this case, the process for measuring the actual Q value is terminated (step S12).

<Collecting SAT temperature, external temperature data and temperature data>
The temperature data collection processing from the temperature data collection unit 12 performed by the Q value measurement processing unit 10 in steps S8 to S11 in FIG. 4 will be described with reference to FIG.
The control unit 105 counts time with an internal timer, and from the temperature data collection unit 12, the temperature data of the SAT temperature, the outside air temperature, and the room temperature are converted into temperature data for each preset measurement cycle of the Q value. Read from the collection unit 12 and output to the input data processing unit 106.
Here, the input data processing unit 106 collects temperature data from each thermometer input from the temperature data collection unit 12 for each measurement cycle, and corresponds to each project described later, corresponding to thermometer identification information. Then, the data is written and stored in the building data storage area in the storage unit 103.

At this time, the input data processing unit 106, when there is a missing measurement (missing temperature data) in the temperature data from the SAT thermometer 220, the outside air thermometer 221, the indoor thermometer 311 to 314,. The temperature data collection unit 12 recollects the temperature data of the SAT temperature, the outside air temperature, or the room temperature.
Further, the input data processing unit 106 displays a communication error on the display screen of the display unit 104 when it detects a communication abnormality with the temperature data collection unit 12 (for example, a response signal is not detected with respect to the transmission signal). To do.

In addition, the input data processing unit 106, when the missing measurement is not resolved even after a predetermined time has elapsed from the collection timing of the measurement cycle for collecting each temperature data of the SAT temperature, the outside air temperature, and the room temperature,
Current temperature Tn = previous measurement temperature Tn-1 + (previous measurement temperature Tn-1−previous measurement temperature Tn-2)
By calculating the correction formula, the missing portion of each temperature data is complemented.
In addition, when abnormal temperature data (such as a very rapid temperature rise or temperature drop, temperature data with an impossible numerical value) is detected due to a communication error or the like, the input data processing unit 106 responds. The temperature data is compared with the temperature data of other thermometers without any missing temperature data.

For example, when the current temperature data is compared with the temperature data of the previous measurement and an increase of 5 ° C. to 10 ° C. is detected, the input data processing unit 106 determines that all other thermometers without any defects (for example, If there are twelve thermometers and ten thermometers without defects, the temperature data is corrected by the above correction formula if there is a difference of 5 ° C. or more.
Further, the input data processing unit 106 compares the current temperature data with the previous temperature data, and if there is an increase exceeding 10 degrees, the input data processing unit 106 does not compare with the data of the thermometer without any loss of other temperature data. Correct the temperature data using the correction formula.

Further, the input data processing unit 106 is configured so that the temperature data from the thermometers outside the building (the outside air thermometer 221 and the SAT (equivalent outside air) thermometer 220) are between the current temperature data and the previous temperature data. Even when the temperature exceeds 10 ° C., the above correction formula is used for correction.
Further, the input data processing unit 106 takes the arithmetic average as (current + previous time + previous time) / 3, and then writes it in the building data storage area of the storage unit 103 corresponding to the thermometer identification information.

<Measurement Process of Actual Q Value by Q Value Measurement Processing Unit 10>
With reference to FIG. 1 and FIG. 2, the measurement process of the actual Q value in the present embodiment will be described.
When the Q value measurement processing unit 10, the measurement unit control unit 11, and the temperature data collection unit 12 in the Q value measurement system 1 of FIG. 1 are activated, the Q value measurement processing unit 10 activates a program for measuring actual Q values. The control unit 105 reads out and displays the screen for inputting the building data (measurement outline data of the building that measures the actual Q value) shown in FIG. 5 from the storage unit 103 as screen data. For each input screen described below, the control unit 105 reads out image data from the storage unit 103 and displays it on the display unit 104.
Then, the control unit 105 detects that the input of input data by the user has been completed when the user presses the apply button on the input screen, and the user inputs to each input field of the input screen shown in FIG. The measured measurement data is written in the building data storage area of the storage unit 103 and stored in correspondence with the project name input by the user. Thereafter, the user presses the input screen with an input device such as a mouse.

Here, the input measurement summary data includes the project name (identification information for identifying the measurement processing of the actual Q value of the building), the measurement name (name of the building to be measured), and the client (requested measurement of the actual Q value) Person or corporation name), measurement period (actual Q value measurement period), Q value floor area used for Q value analysis (input floor area for each floor), Q value air volume used for Q value analysis (simple This is the ceiling height (distance from the floor to the ceiling) of each floor for obtaining the ventilation (air volume) of the heat loss coefficient calculation table of the Q value calculation, and the air volume of the space other than the room.
When the data input on the display screen of FIG. 5 is completed and the apply button is pressed with a mouse or the like, the control unit 105 corresponds to the project name and the measurement summary data (Q value floor area, Q value memory). Product) is stored in the building data storage area in the storage unit 103.
At this time, the control unit 105 adds the input floor areas of the respective floors, obtains the total floor area, and writes and stores the total floor area together with the floor area in the building data storage area.
In addition, the control unit 105 multiplies the ceiling height and the floor area for each floor, obtains the air volume for each floor, stores the air volume for each floor in the building data storage area, and stores the air volume for each floor. The volume other than the room is added, and the total volume is written and stored in the building data storage area as a volume for Q value.

When the data input on the display screen of FIG. 5 is completed, the writing of the data to the storage unit 103 is completed, and the user selects the building overview tab of FIG. 6, the control unit 105 displays the input screen shown in FIG. The building summary data displayed on the unit 104 and input by the user to each input column of the input screen is written in the building data storage area of the storage unit 103 and stored in association with the project name input by the user. Here, the control unit 105 detects that the user has pressed the apply button on the input screen, and writes the building outline data entered in each input column by the user in the building data storage area.
Here, the input measurement summary data is the building name, location, date of completion, floor area for building confirmation, floor area for simple calculation, finishing (finishing material data), insulation (insulation used for each part) Material type) and openings (materials and structures of openings such as windows and doors).
The control unit 105 calculates (subtracts) the building age from the current date and time and the completion date, and fills the final report with the building age corresponding to the project name. Like the measurement summary data, the data is written and stored in the building data storage area of the storage unit 103. The numerical value entered in the entry field of the floor area for simple calculation is used for simple Q value calculation described later.

Further, when the user inputs a calculated Q value or an assumed Q value, the control unit 105 writes and stores it in the building data storage area of the storage unit 103 corresponding to the project name.
Here, if the design Q value (Q value calculated according to the energy saving standard) or the assumed Q value (Q value obtained in a similar building in the past) is unknown (that is, if it is not input), the Q value calculation is performed. Since the unit 107 cannot appropriately determine the amount of heat generated by the heater, the control unit 105 causes the simple Q value calculation unit 108 to perform simple Q value calculation and obtains and uses the obtained calculated Q value. This simple Q value calculation will be described later, but information set by inputting information such as the floor area of each room of the building by the user selecting the area input button at the bottom of the display screen (FIG. 19). Calculated from

In addition, the control unit 105 includes a finishing material (finishing material) such as a roof, a ceiling, an outer wall, an inner wall, and a floor, a thickness of each finishing material, a material of a heat insulating material used for the roof, the wall, and the foundation, The thickness and area are input by reading data input by the user into the input field, corresponding to the project name, and written and stored in the building data storage area of the storage unit 103.
In addition, the control unit 105 sets the window frame material of the window, the window material (the type of glass, the number of stacked sheets), the window area, the door material, the presence of glass, and the door area as the opening. Data to be input to the input field is read and input, and is associated with the project name, written in the building data storage area of the storage unit 103, and stored.
Further, the control unit 105 selects the heat generation coefficient displayed in the setting of the measuring instrument in FIG. 8 to be described later. Information on whether or not the floor area of the second floor is significantly smaller than the first floor, with or without open stairs, or with or without ceiling insulation on each floor ("with ceiling insulation on each floor") (“The floor area of the second floor is significantly smaller than the first floor”) is stored in the building data storage area of the storage unit 103 in association with the project name.

Next, in order to obtain the calculated Q value, the control unit 105 displays an input screen for calculating the calculated Q value on the display unit 104 when the user presses the area-specific area input button with a mouse or the like.
Then, in order to calculate the calculation Q value of the input screen, the simple Q value calculation unit 108 reads the data input by the user into the input field, calculates the calculation Q value (details will be described later), and calculates the result Q The value is associated with the project name, and is written and stored in the building data storage area of the storage unit 103.

Next, when the user inputs the measured C value or the assumed C value, the control unit 105 writes and stores it in the building data storage area of the storage unit 103 corresponding to the project name.
Here, the user inputs an actually measured C value (C value already measured in step S1 in the flowchart of FIG. 4) or an assumed C value (C value obtained in a similar building in the past).

  Then, when it is detected that the user's data input on the display screen of FIG. 6 is completed and the apply button is pressed, the control unit 105 causes the display unit 104 to display the input screen shown in FIG. The indoor thermometer setting data input by the user for each input field is written in the building data storage area of the storage unit 103 and stored in association with the project name input by the user. That is, the control unit 105 writes and stores each data input by the user described below in the building data storage area corresponding to the project name as the table format of the correspondence in the input field of FIG.

  The user selects the indoor thermometer setting tab in the display screen of FIG. 7, and in the indoor thermometer setting input screen displayed by the control unit 105, the thermometer identification information (see FIG. No. 1 to No. 12) In the non-use information indicating that the corresponding indoor thermometer is not used depending on whether or not the check box on the right side of each is selected. For example, when the user selects a check box, the control unit 105 associates non-use information indicating that the corresponding indoor thermometer is not used with the thermometer identification information of the indoor thermometer, and the building data in the storage unit 103 Write and store in the storage area. Thereafter, when non-use information is added corresponding to the thermometer identification information, the storage unit 103 does not input this data even if the data related to the corresponding thermometer is entered by the user in the input field. Not performed.

Next, the user inputs the temperature measurement range indicating the type of room in which the indoor thermometers (311 to 314,...) Are placed, that is, the region in which the temperature of the indoor thermometer is measured. That is, the user inputs the floor where the indoor thermometer is arranged, the room name, the floor area and the height (distance from the floor to the ceiling) of this room in the corresponding fields, and is not shown in the input screen. Press the calculation button with an input device such as a mouse.
When the calculation button is pressed, the control unit 105 detects that the calculation button is pressed, reads the data input in the input field, and for each temperature measurement range of each indoor thermometer, The volume of the temperature measurement range is calculated by multiplying the floor area and the height, and is displayed in correspondence with the thermometer identification information of the corresponding indoor thermometer.

Further, the control unit 105 adds all the volumes of the temperature measurement range in the building, obtains the total volume as the addition result, divides the volume of each temperature measurement range by this total volume, and calculates the total of the buildings in each temperature measurement range. The relative volume, which is the proportion of the volume, is calculated and displayed in correspondence with the thermometer identification information of the corresponding indoor thermometer. The relative volume calculated here is used for weighted averaging of the room temperature of each room, that is, when obtaining the room temperature when the building is one room, the temperature data is obtained by weighted averaging the room temperature of each room in the building. Calculated as temperature data when the building is one room.
In addition, the control unit 105 calculates the number of thermometer identification information for which the check box is not selected, and displays the number as the number of installed room temperature meters in the column of the number of installed room temperature meters on the input screen.
When the user presses the apply button on the input screen with an input device such as a mouse, the control unit 105 causes the building data storage area of the storage unit 103 to correspond to each thermometer identification information in association with the project name. The temperature measurement range (floor and room information), floor area, height, volume, relative volume, and number of installed room temperature meters are written and stored in the building data storage area of the storage unit 103.

When the data input on the input screen of FIG. 7 is completed, the control unit 105 displays the input screen shown in FIG. 8 on the display unit 104, and the measurement device settings input by the user in each input field of this input screen. Is written in the building data storage area of the storage unit 103 and stored in correspondence with the project name input by the user.
The control unit 105 calculates the Q value floor area corresponding to the project name currently being processed from the data stored for each project name in the storage unit 103 as the Q value floor area input in the measurement outline of FIG. Is output (displayed) in the column of the total floor area where the Q value is used on the input screen.

  Next, when the user selects a tab indicating an input screen for measuring instrument settings on the display screen of FIG. 8, the control unit 105 reads and calculates data on the internal and external temperature difference input in the input field for internal and external temperature difference on the output screen. Multiplying the Q value (or assumed Q value), the floor area for the Q value, and the read internal / external temperature difference, the total calorific value of the building is calculated. Here, the user selects or directly inputs the data of the internal / external temperature difference in the range of 10 to 15 ° C. At this time, when the user presses the button of the specified value on the input screen with an input device such as a mouse, the control unit 105 detects that the button of the combo box of the internal and external temperature difference is pressed, and the temperature of 10 to 15 ° C. Display temperature. When the user selects any of the displayed internal / external temperature differences with an input device such as a mouse, the control unit 105 sets the selected data as the internal / external temperature difference and displays it in the internal / external temperature difference input field.

When the user presses a calculation button on the input screen with an input device such as a mouse, the control unit 105 reads the heat generation coefficient from the heat generation coefficient table stored in the storage unit 103, and generates a heat generation coefficient corresponding to each floor on the input screen. Is displayed in the column. In this heat generation coefficient table, the heat generation coefficients are “calculated Q value (or assumed Q value)”, “with a stairwell or open staircase”, “with ceiling insulation on each floor”, and “floor area on the second floor is the first floor” Corresponding to a combination of “remarkably smaller” data, it is stored for each floor. Here, the “calculated Q value or assumed Q value” and “actually measured C value or assumed C value” are each quantized within a set numerical range, and the Q value calculator is within the quantization range. A heat generation coefficient in the table is selected.
Here, the control unit 105 corresponds to the name of the project currently being processed from the building data storage area of the storage unit 103, and "calculation Q value (or assumed Q value)", "there is an open or open staircase" , “With ceiling insulation on each floor” and “the floor area of the second floor is significantly smaller than the first floor”, and read the heat generation coefficient corresponding to the combination from the heat generation coefficient table for each floor in the storage unit 103 The total heat generation coefficient is obtained by adding the heat generation coefficients of all the floors as the heat generation coefficient of each floor.

Then, the control unit 105 multiplies the calculated heat generation amount for each floor by the heat generation coefficient of the floor, divides the multiplication result by the total heat generation coefficient, obtains the heat generation amount per floor, Is displayed in the column of the calorific value per floor of the input screen (the total calorific value supplied by each heater arranged on that floor). Here, the heat generation coefficient for each floor is a coefficient that is set to 1 for the lowest floor, for example, the first floor, and lower for higher floors, and sets the ratio of the heat generation amount to the floor in the entire building. Therefore, this heat generation coefficient is set to be lower than that of the lower floor because the air heated by the heat energy moves in the higher floors.
Further, the control unit 105 reads the Q value floor area of each floor from the building data storage area of the storage unit 103 corresponding to the name of the project currently being processed, and the above-described Q value floor area of each floor is The calorific value per floor is divided to obtain the calorific value per floor area of each floor, and is displayed in the column of the calorific value per floor area of the floor of the input screen for each floor.
When the user presses an apply button on the input screen with an input device such as a mouse, the control unit 105 detects that the apply button has been pressed, and generates a calorific value per floor for each floor in association with the project name. Then, the heat generation amount per floor area and the heat generation coefficient are written and stored in the building data storage area of the storage unit 103.

Then, when the data input on the input screen of FIG. 8 is completed and the user detects that the tab indicating the input screen for setting the heat generation amount on the display screen of FIG. 8 is selected, the control unit 105 displays the input shown in FIG. After the screen is displayed on the display unit 104 and the input to each input field is completed, when it is detected that the user has pressed the button for only applying the input screen in FIG. The calorific value setting data input by the user is written and stored in the building data storage area of the storage unit 103 in correspondence with the project name input by the user.
For the thermometer column, the control unit 105 associates the name of the project currently being processed from the building data storage area of the storage unit 103 with the temperature of the indoor thermometer for each thermometer identification information of the indoor thermometer to be used. The measurement range (floor, room name) and floor area are read out, and the respective floor, room name and floor area are displayed in correspondence with the thermometer identification information in the relevant column of the input screen.

And the control part 105 reads the emitted-heat amount per floor area of each floor from the building storage data area of the memory | storage part 103 corresponding to the project name currently processed, and with respect to the floor area of each temperature measurement range for every floor, By multiplying the calorific value per floor area, the calorific value of each room in each temperature measurement range is obtained, and the calorific value (necessary calorific value) of each temperature measurement range in the input column is displayed for each temperature measurement range. Displays the calorific value obtained for each room.
Next, the user sets a heater that provides a calorific value in each temperature measurement range. Here, in the present embodiment, when one measurement unit (unit identification unit 1 or unit 2 or the like, which is unit identification information) is added and data corresponding to the measurement unit is stored in the storage unit 103, the unit identification information corresponds to the unit identification information. In order to control the two heaters, two control units (hereinafter referred to as channels) Ch1 and Ch2 are provided.
Here, the user identifies the thermometer identification information (No.) of the indoor thermometer arranged in the temperature measurement range where the heater is arranged for each of the thermometer columns of the channels Ch1 and Ch2 in the unit of measurement unit by the unit identification information. .1 to No. 12). In the present embodiment, three thermometers can be associated with each measurement unit channel. One heater for each channel corresponds to the size of the volume of the room or area to which the heater supplies energy, and up to three thermometers are arranged for each part of the room or area. be able to.

In the input column of the thermometer of each channel in the unit, the control unit 105 is used when the user selects a button for displaying a combo box provided in the thermometer identification information input column of the thermometer of each channel. A list combo box displaying all the thermometer identification information (No. 1 to No. 12) of the indoor thermometer is displayed.
Then, the control unit 105 selects the thermometer identification information selected by the user from the combo box list using an input device such as a mouse, as the thermometer column of each channel Ch1 and Ch2 in each measurement unit corresponding to the unit identification information ( Each of them is displayed in correspondence with the unit identification information (in correspondence with the input thermometer column).
And the control part 105 is made to respond | correspond to each channel Ch1 and Ch2 of each measurement unit, and the room name (for example, living room, dining room) where the indoor thermometer corresponding to the thermometer identification information input into the thermometer column is arrange | positioned. Child room) or area name (for example, corridor, entrance, stairs, etc.) and location information including floor information (for example, 1st floor, 2nd floor, etc.), and floor / room name corresponding to the channel number, respectively. (And area name) column.

Further, referring to the necessary heat generation amount corresponding to the temperature measurement range of the indoor thermometer, the user can connect the heat generation amounts corresponding to the channels Ch1 and Ch2 of each measurement unit to the channels Ch1 and Ch2 (202, 203, 212, 213,...)).
When the heating value of each heater is input to the heating value column of the channels Ch1 and Ch2, the control unit 105 reads the input heating value and displays this heating value in the adjacent current setting value column. Here, in the input field for the calorific value of each channel in the unit, the control unit 105 clicks an adjustment button for increasing and decreasing the temperature provided in the input field for the calorific value of each channel with a mouse or the like. Thus, the heat generation amount of the heater that can be set is displayed. When the user clicks the raise button, the temperature is raised, so the heater's heating value higher than the current setting is displayed (in the case of the type where the heating value is switched by the heater switch, in the order of 200, 400, 600, 800). In the case of the type in which the amount is controlled by the power regulator, the order is 50, 100, 150, ..., 650, 700.) On the other hand, when the lowering button is clicked, the control unit 105 sequentially displays the heat generation amount of the heater lower than the current one in order to lower the temperature.
In other words, the control unit 105 displays all the settable heat generation amounts increased for each unit heat generation amount in the range from the lowest heat generation amount that can be used by the corresponding heater to the maximum heat generation amount in the column of the heat generation amount. A table is displayed, and the calorific value selected by an input device such as a mouse from the list is displayed in each calorific value column of each channel Ch1 and Ch2 in each measurement unit. This calorific value is displayed in the currently set value column.

  Further, when adjusting the temperature of each room during measurement of the actual Q value, the amount of heat generated by each heater is also adjusted on the input screen shown in FIG. However, when the calorific value is changed during measurement of the actual Q value, the total calorific value obtained by adding all the heaters needs to be the same as the total calorific value at the start of measurement. Here, the provisional total of the calorific values needs to match the total of the currently set values, and if the comparison result does not match, the control unit 105 measures the calorific value as the heater control value. It cannot be transmitted to the unit controller 11.

Further, instead of the user inputting heat generation amount, when the thermometer identification information is input to the channels Ch1 and Ch2 corresponding to the heater, the heat generation amount set by the control unit 105 may be selected. That is, the control unit 105 reads the necessary heat amount corresponding to each thermometer identification information, and extracts the heat value closest to the necessary heat value from the heat value that can be set by the corresponding heater (for example, each heat value that can be set). The difference between the calorific value and the required calorific value is taken and the calorific value that can be set with the smallest difference is extracted), and this extracted calorific value is displayed in the column of the calorific value of channels Ch1 and CH2 corresponding to each measurement unit. To display.
When the user presses an application-only button on the input screen with an input device such as a mouse, the control unit 105 generates heat for each temperature measurement range in the building data storage area of the storage unit 103 in association with the project name. In addition to writing the amount, the temperature measurement range (floor, room name), effective heat generation amount, and currently set heat generation amount are written and stored for each channel Ch1 and CHh2 of each measurement unit indicated by the unit identification information.

When adjusting the internal temperature distribution for each room, that is, for each temperature measurement range, the position of the fans (204, 205, 214, 215,...) Arranged in each temperature measurement range, the air volume, or the heating value of the heater This is done by adjusting the balance and changing the efficiency of stirring of the internal air. Here, the balance of the heat generation amount is to set the heat generation amount between the heaters arranged in each room, and to set the numerical value of the total heat generation amount of the entire building to a constant value in the temperature increase in the Q value calculation. Therefore, the amount of heat generated between the heaters in each room is adjusted, and the temperature inside the building is made uniform with the amount of heat generated throughout the building being constant.
The temperature difference between the upper floor and the lower floor can be adjusted by adjusting the heating value of the heater between the upper floor and the lower floor, or by placing a duct fan on the stairs or in the atrium. This is done by agitating the air with the lower floor.

Then, when it is detected that the user's data input on the input screen of FIG. 9 has been completed and the “apply only” button has been pressed, each input field of the calorific value setting that the user has input to each input field of this input screen Is written in the building data storage area of the storage unit 103 and stored in correspondence with the name of the project currently being processed. When the user selects the start setting tab in FIG. 9 with a mouse or the like, the control unit 105 causes the display unit 104 to display the input screen shown in FIG.
The control unit 105 reads the effective heat generation amount for each channel Ch1 and Ch2 of each measurement unit from the building data storage area of the storage unit 103 in correspondence with the name of the project currently being processed and the unit identification information, and measures each measurement. The effective heat generation amounts of the channels Ch1 and Ch2 for each unit are totaled, and the total value obtained for the heat generation amount of each heater for each measurement unit in the start setting area is displayed in the column of the total value of the corresponding heater.

Further, the control unit 105 reads the time of the internal timer, and displays the read time in the current date and time column of the input screen (performs this process for each preset period).
The user inputs the measurement period (for example, the number of days and the number of hours) of the actual Q value in the measurement period setting field. During this measurement period, the Q value measurement system 1 measures the actual Q value, and when the set measurement period has elapsed, for example, in FIG.
In addition, the user inputs the start date and time of the heater connected to the measurement unit in the start date and time column in the item of heater operation timing.
When the user presses the setting transmission button with an input device such as a mouse, the control unit 105 displays the start date and time (date and time when the start-up operation is started) in the measurement start item and the time until the start-up operation is started. .
Here, the time displayed by the control unit 105 is, for example, a time that is not less than 1 minute and less than 2 minutes from the time when the setting transmission button is pressed, and is the time when the second of the start time becomes 0 seconds. The reason why the start time is determined in such a way is because of the format of the previous measurement (storage) data of the measurement unit controller 11 and the time required to set the current measurement.
When the user selects the setting transmission button at the bottom of the display screen with a mouse or the like, the control unit 105 reads the start date / time of the heater movable timing and the start date / time of the run-up operation from the corresponding columns.

  Then, when the user presses a setting transmission button on the input screen with an input device such as a mouse, the control unit 105 sets the temperature measurement range (floor) for each of the channels Ch1 and CHh2 of each measurement unit input by the user in FIG. , Room name) and effective calorific value corresponding to the name of the project currently being processed, read out from the building data storage area of the storage unit 103, and together with the start date and time of the heater movable timing, the measurement unit control unit 11 is transmitted.

In addition, when transmitting setting data indicating the correspondence between the temperature measurement range and the effective heat generation amount, the control unit 105 reads the time of the internal timer to set the time with the measurement unit control unit 11 and sets the time. The data is transmitted to the measurement unit controller 11 together with the data corresponding to the temperature measurement range and the effective heat generation amount.
At this time, the control unit 105 associates the total value of the heaters for each measurement unit indicated by the unit identification number and the start date / time of the heater movable timing with the name of the project currently being processed in the building data storage area of the storage unit 103. Write and store.
In addition, when the measurement unit control unit 11 transmits a response signal indicating that the data in which the temperature measurement range is associated with the effective heat generation amount is normally received, the control unit 105 receives the response signal. Displays the character data indicating normality in the area of the Q value measurement system state on the display screen, and the state where the measurement start button can be selected at the bottom of the display screen, that is, the state where the control signal for controlling the measurement start can be input And
On the other hand, when the measurement unit control unit 11 transmits a response signal indicating that the data in which the temperature measurement range and the effective heat generation amount are associated with each other cannot be normally received, the control unit 105 receives the response signal. Thus, as shown in FIG. 10, character data (error) indicating that it is not normal is displayed in the area of the Q value measurement system state on the display screen, and the measurement start button at the bottom of the display screen cannot be selected, that is, The control signal that controls the start of measurement is disabled. Here, the control unit 105 uses this measurement start button to send a response signal indicating that each data has been input to each input field of the input screen of FIG. 10 and that the data has been normally input from the measurement unit control unit 11. After reception, the measurement start button can be selected, and before that, the selection is impossible.
Further, in the storage area corresponding to each project in the storage unit 112 in the measurement unit control unit 11, the temperature measurement range for each measurement unit or the data corresponding to the effective heat generation amount, or the heat collected from each measurement unit. When checking the quantity data, the file name (with directory name, for example, \\ Spu-default \ pccards \ PCCard1 \ Data.csv) that indicates the link destination in the address input field in the display field for the exothermic data reference When the reference button is selected with a mouse or the like, the control unit 105 accesses the measurement unit control unit 11, reads the file in the storage unit 112, and displays the file data on the display screen.

As described above, the measurement unit control unit 11 receives the setting data, the start date / time of the heater operation timing, and the current date / time by the transmission / reception unit 113, and the control unit 111 writes the setting data and the start date / time of the heater operation timing in the storage unit 112. The time of the current date and time of the received time setting data is set for an internal timer (not shown).
Further, as described above, the measurement unit control unit 11 adds to the data whether or not the temperature measurement range for each measurement unit input from the Q value measurement processing unit 10 or the data of the effective calorific value has been normally received. The response signal indicating that the signal was successfully received is transmitted to the Q value measurement processing unit 10 when the signal is normally received. When the signal is not normally received, the signal is normally received. A response signal indicating that it could not be transmitted is transmitted to the Q value measurement processing unit 10.
Then, when the control unit 111 is able to receive normally, the control unit 111 displays the time of the internal timer on the touch panel unit 114 and also displays the heat generation amount corresponding to the channels Ch1 and Ch2 for each measurement unit as setting data on the touch panel unit 114. To do.

  When the user presses an application-only button on the input screen using an input device such as a mouse, the control unit 105 corresponds to the name of the project currently being processed, and determines the total heater value for each measurement unit and the heater movable timing. Only the process of writing and storing the start date and time in the building data storage area of the storage unit 103 is performed, and the setting data is not transmitted to the measurement unit control unit 11.

Further, when the user selects a test run button at the bottom of the input screen shown in FIG. 11 with an input device such as a mouse, the control unit 105 displays the input screen shown in FIG. 11 as an input screen for setting the test run on the display unit. Is displayed on the display unit 104. This input screen includes an input field for setting a calorific value (unit calorific value × n, n = 1, 2, 3,...) To be added to the heater set value for each heater in each measurement unit, and a test run. An input field for setting an operation time as a period is provided. Here, the heat generation amount to be added to the current set value can be arbitrarily selected from a list of numerical values of the heat generation amount of the combo box. In this embodiment, 50 W or 100 W can be set. .
When the user inputs the heater set value and the operation time in the respective fields and presses the start button on the input screen with an input device such as a mouse, the control unit 105 displays the input screen shown in FIG. In addition, the heater set value and the operation time are transmitted to the measurement unit controller 11 together with a control signal indicating that it is a trial operation. As shown in the input screen of FIG. 12, the control unit 105 changes the test operation button on the input screen of FIG. 10 to a test operation stop button and displays it as an input button for detecting the stop of the test operation.

Here, in the measurement unit control unit 11, the control unit 111 detects a trial operation based on the control signal received via the transmission / reception unit 113, and the received heaters for the heating values of all currently set heaters. A set signal is added, and a start signal (a heat generation amount is added) for starting the operation of the heater connected to Ch1 and Ch2 of each measurement unit of the unit identification information is added to each measurement unit based on the heat generation amount after the addition. When the internal timer detects that the operation time has elapsed since the start, a stop control signal for stopping the operation of the heater is transmitted to each measurement unit to end the test operation.
At this time, each measurement unit operates and controls the heater (including the fan with each heater built-in) and drives the fan so as to release the instructed calorific value based on the start signal transmitted from the measurement unit controller 11. Let
Here, in the test run and in the actual measurement, the measurement unit controller 11 provides a time difference to each measurement unit and transmits the start signal in a preset order. As a result, the heaters start operating at the same time, and the load current during the operation flows simultaneously, thereby preventing the breaker of the Q value measurement target building from falling.

Since this test operation uses a lot of power to measure the measured Q value, it is confirmed whether the breaker of the building to be measured does not drop by the test operation and whether the measuring instrument is operating as specified. To do.
In addition, when the user presses a test operation stop button on the input screen with an input device such as a mouse, the control unit 105 transmits a stop control signal indicating the test operation stop to the measurement unit control unit 11.
When the stop control signal is received, in the measurement unit control unit 11, the control unit 111 transmits the stop control signal to each measurement unit.
Thereby, each measurement unit stops the heater (including the fan with each heater built-in) and the fan.

When the user presses a measurement start button on the input screen with an input device such as a mouse, the control unit 105 records the previous project stored in the storage unit 112 of the measurement unit control unit 11 with respect to the current time. The time required for initializing (formatting) the data (for example, 60 to 120 seconds) is added to the transmitted measurement start date and time to obtain the measurement start date and time. To the measurement unit controller 11.
At this time, the control unit 105 displays the measurement start date and time in the column of the date and time of the measurement start item, and writes and stores them in the building data storage area of the storage unit 103 in association with the project name currently being processed. .
Here, the recorded data in the storage unit 112 is the power consumption used for heating the Ch1 and Ch2 heaters of each measurement unit (for example, 20, 21), that is, in each heater connected to the measurement unit. Power consumption (power consumption of the built-in fan, power consumption of the fan connected to the heater outlet) and consumption to operate the fan connected to each measurement unit (power consumption of the fan connected to the outlet) Power, power consumption of the measurement unit itself (internal circuit, etc.), electronic equipment connected to a constant outlet of the measurement unit (for example, power consumption of household appliances that cannot be stopped, power consumption of the measurement unit controller 11, Q value) Each of the measurement processing units 10 (power consumption) measures the measurement period (measurement) for measuring the Q value corresponding to the measurement unit identification. It is recorded for each cycle). If the total amount of power consumed by each measuring unit is always constant, the measured Q value can be measured with high accuracy.

When the start control signal is received and input, in the measurement unit control unit 11, the control unit 111 writes and stores the measurement start date and time input together with the start control signal in the storage unit 112.
Then, the control unit 111 formats the storage area of the measurement data in the storage unit 112, and after the formatting is finished, the measurement start date and time stored in the storage unit 112 Detected by comparing with the time of the timer, and when it is detected that both match, a control signal for starting the operation of the heater connected to Ch1 and Ch2 of each measurement unit is transmitted corresponding to the unit identification information To do. As a result, when each measurement unit receives a control signal for starting the driving of the heater, the built-in power regulator starts driving the corresponding heater so that the heating value set for each heater is obtained. To do.
That is, the control unit 111 controls the amount of heat generated by each heater by reading the set value of the amount of heat generated by each heater stored in the storage unit 112 and corresponding to the set value, To adjust the calorific value.
At this time, if the heater moving timing is set before the measurement start date and time, the start control signal for starting the measurement is not transmitted to the measurement unit control unit 11, and the input screen of FIG. An error display is displayed in the column of the Q-factor measuring device system status. The column of the Q value measuring device system state is for displaying the operating state of the Q value measuring system 1.
At this time, each measurement unit supplies power to the outlet and drives the connected fan (the air volume may be adjusted by a power regulator), or the fan connected to the heater outlet also drives. Start.

  Next, the control unit 105 displays the display screen of the measurement result (room temperature, monitoring of the amount of heat generated by the heater) shown in FIG. In the A1 area of FIG. 13, a graph of the variation in the heat generation amount of each heater over time is displayed, the horizontal axis indicates time (Q value measurement period), and the vertical axis indicates the heat generation amount in each measurement unit. ing. In the B1 region of FIG. 13, a graph of the variation in temperature measured by each thermometer (indoor thermometers 311 to 314,..., SAT thermometer 220, outdoor thermometer 221) over time is displayed. Indicates time, and the vertical axis indicates temperature.

That is, in the control unit 105, the input data processing unit 106 transmits a temperature collection control signal to the temperature data collection unit 12 through the transmission / reception unit 101 in the measurement cycle (for example, a 5-minute cycle), and responds to this temperature collection signal. Then, the temperature data from each thermometer (the indoor thermometers 311 to 314,..., The SAT thermometer 220, the outside air thermometer 221) transmitted from the temperature data collecting unit 12 is processed as described above, The temperature data of the thermometer is plotted for each measurement period in the B1 region.
In addition, the control unit 105 transmits a heat generation amount collection control signal to the temperature data collection unit 12 for each measurement cycle, and for each unit identification signal transmitted from the measurement unit control unit 11 corresponding to the heat generation amount collection control signal. The input calorific value of each measurement unit (the calorific value of the heater connected to Ch1, Ch2, the calorific value of the fan, and the calorific value of the measurement unit in total of the calorific value of the internal circuit) is A1 for each measurement unit. Plot every measurement period in the region.

  Next, when the time of the internal timer becomes the start time of the heater operation timing stored in the storage unit 103, the control unit 105 transmits a measurement start control signal to the measurement unit control unit 11 and performs the measurement shown in FIG. A display screen of the results (room temperature, heater heating value monitoring, analysis results) is displayed on the display unit 104. In the present embodiment, the control unit 105 performs the measurement cycle at the same time interval as before the start of heating of the heater when the heating of the heater is started. For example, the control unit 105 sets the measurement period of the Q value to 10 minutes in the present embodiment. Moreover, the temperature data collection part 12 is measuring the temperature data every 5 minutes of a fixed period.

In the area A2 in FIG. 14, a graph of the actual Q value obtained for each measurement cycle is displayed, the horizontal axis indicates time (Q value measurement cycle), and the vertical axis indicates the calculated actual Q value (W / m ² · K). In the B2 region, a graph of the average residual δ obtained for each measurement cycle (relation between heat loss coefficient and average residual) is displayed, the horizontal axis indicates time, and the vertical axis indicates average residual δ described later. The calculated value of (K) is shown. Further, in the C2 region, the total calorific value obtained by adding the calorific values of all the measurement units transmitted from the measurement unit control unit 11 by the control unit 105 is displayed, and the horizontal axis is time (Q value measurement cycle). The vertical axis represents the total calorific value. Further, similarly to the display screen of FIG. 13, a graph in which the temperature data of each thermometer is plotted for each measurement cycle is displayed in the area B1.
Here, in the area A2 and the area B2 in FIG. 14, the control unit 105 displays a line perpendicular to the horizontal axis indicating the time at the time when the average residual δ is the lowest value. This vertical line allows the user to detect the time when the average residual δ is lowest.
The time on the horizontal axis in each graph of FIG. 13 and FIG. 14 indicates the time when the measurement is started from the origin, that is, the time elapsed from when the measurement was started.

Then, the control unit 105 detects that the user has pressed a measurement end button (not shown) on the display screen of FIG. 14 with an input device such as a mouse or the measurement period in the measurement period setting stored in the storage unit 103. And a measurement end control signal are transmitted to the measurement unit controller 11 when it is detected that the time of the measurement timer that counts the measurement period matches.
As a result, the control unit 111 in the measurement unit control unit 11 transmits the measurement end control signal for stopping the heater operation to each measurement unit, and ends the measurement process, that is, the collection of heat generation data from each measurement unit. To do.
When the measurement end control signal is input, each measurement unit stops the heater and the fan.

Next, the control unit 105 displays a display screen showing the result of the analysis data shown in FIG. 15 when the measurement of the actual Q value is completed.
That is, the control unit 105 sets the current Q value by the actual residual Q value identified by the average residual δ and the average residual δ in the time range set by the user in the measurement period described above as described later. The identified Q value identified by the ΔQ value is displayed together with the ΔQ value corresponding to the identified Q value. Here, the control unit 105 outputs, as the ΔQ value, a time range that is equal to or less than a preset numerical value within the entire measurement time range of FIG. The lowest Q value in the range where the ΔQ value is smallest is detected as the actual Q value, and is output as the identification result of the actual Q value.
When the user presses the identification range setting button on the display screen of FIG. 15, the control unit 105 inputs a signal for detecting the pressing, and displays the identification range setting input screen shown in FIG. 16 on the display unit 104. In FIG. 14, the image is displayed on the display screen of FIG. 14 at a position different from the display of FIG.

Then, on the input screen for setting the identification range, the user inputs the start time and the end time in the respective input fields or slide bars as a function for excluding the range that causes the false detection of the Q value such as noise, When the enter button on the input screen is pressed, the control unit 105 detects that the enter button has been pressed, reads the start time and the end time, and inputs the start time and end time to this time range. The lowest Q value is extracted at, and the actual Q value in the identification range is obtained and displayed in the column of the identification Q value in FIG.
When the user presses the close button on the identification range setting input screen of FIG. 16, the control unit 105 detects that this close button has been pressed, and closes the identification range setting input screen shown in FIG. .
When the user presses a report button on an input screen (not shown), the control unit 105 detects that the determination button is pressed, reads a report format file stored in the storage unit 103 in advance, In the output column, report the data such as the measured Q value and ΔQ value, the graph of the measured Q value and average residual δ of FIG. 16, the building outline, and the measurement outline, for example, as a result report (report) by a printer Print.

In addition, an abnormality that has been foreseen in the measurement has occurred, and when the control unit 105 detects this abnormality, the control unit 105 notifies the preset mail address via the transmission / reception unit 101 of the abnormality detection Can be set to send e-mails.
When an abnormality to be described later is detected, the control unit 105 reads the mail address corresponding to the name of the project currently being processed in the storage unit 103, describes the type of abnormality and its numerical value in an alarm mail, and reads the read mail. Send to address.
The period for sending the alarm mail, the abnormality name, and the reference value for detecting the abnormality are set in advance in the storage unit 103 corresponding to the project name.
The abnormality name and its reference value are, for example, the following items. The alarm mail is set to be transmitted at an arbitrarily set cycle (for example, 60 minutes).

・ Temperature abnormality Even when the room temperature has exceeded the temperature and time set in the storage unit 103, the temperature exceeding the set temperature continues. , The interval at which the temperature rises and changes from the set temperature is measured, and if this interval exceeds the set temperature, it is detected as a temperature abnormality.

・ Temperature data acquisition abnormality This is a case where the number of missing data exceeds the set number of times from any one of the thermometers (indoor thermometer, outdoor thermometer, SAT thermometer). The number of times that the temperature data to be read is missing is counted for each thermometer identification information.

・ Temperature difference abnormality Even when the room temperature exceeds the time set in the storage unit 103, the room temperature does not become constant, and the control unit 105 sets the temperature data of each indoor thermometer for each set measurement cycle. If the temperature difference changes for more than the set time, it is detected as a temperature difference abnormality.

・ Abnormal calorific value This is the case where the output after the start of heat generation is either below the lower limit ratio (for example, 70% or less) of the calorific value setting or above the upper limit ratio (for example, 130% or higher). The control unit 105 reads the heat generation amount data of each unit for each measurement cycle, and detects that the heat generation amount is abnormal when it detects that the set output is less than the set lower limit ratio or more than the upper limit ratio.

In addition, even when it is detected that processing is normally performed, a configuration may be adopted in which notification that processing is normally performed by e-mail is made.
For example, if none of the above is detected for each set time and is processed normally, the control unit 105 is processed normally by e-mail for the set address. To be notified.

Further, in the measurement instrument setting, as shown in FIG. 9, the user does not change the heat value of each measurement unit from the value initially set, but the control unit 105 detects the variation in the temperature of each room, Settings can be made to control the amount of heat generated by each measurement unit so that the temperature between the rooms is uniform. In this case, as a premise of the control, one thermometer is associated with each heater corresponding to each Ch1 and Ch1 heater in each measurement unit.
When the user presses the option setting button on the display screen of FIG. 9, the control unit 105 detects that the option setting button has been pressed. An input screen shown in FIG. 17 for inputting conditions for controlling the amount of heat generated by the heater is displayed on the display unit 104. That is, the input screen of FIG. 17 is an input screen for data necessary when the control unit 105 performs automatic control of the heat generation amount.
The control unit 105 adjusts the calorific value of each Ch1 and Ch2 of each measurement unit indicated by the unit identification information based on the temperature data from each indoor thermometer acquired from the temperature data collection unit 12.

The user sets the maximum value of the calorific value of each Ch1 and Ch2 of each measurement unit and the correction value of the power of the measurement unit itself and the fan (the calorific value correction range centering on the calorific value set in FIG. 9). input.
In addition, the user inputs a time during which heat generation amount adjustment control is performed after the start of heat generation (for example, after one hour has elapsed), and a time during which adjustment control is continued (continuous for 7 hours), and time when adjustment control is not performed. A band (for example, between 07: 00 and 18:00, that is, during the daytime when the user is working) is input.
Also, the temperature difference between the rooms where the heat generation amount is controlled (for example, 2 ° C or 3 ° C as the temperature difference setting temperature, and if the temperature is lower than the setting temperature, the heat generation amount is not adjusted. The amount of heat adjustment interval (for example, 30 minutes), and the unit for adjusting the amount of heat generated by the heater corresponding to the maximum or minimum room temperature in the measured temperature data (for example, ± 50 W) Enter the calorific value of the unit to be adjusted.
When the user inputs each data described above into the input field and presses the save button on the input screen, the control unit 105 detects that the save button is pressed, and the data input in each input field. Are associated with the project name, written and stored in the building data storage area of the storage unit 103, and after the start of heat generation, the time for adjusting the heat generation amount, the time for continuing the adjustment control, and the time for the adjustment interval The temperature difference of each room where the heat generation amount control is performed is stored.
In addition, when one indoor thermometer corresponds to one heater (one indoor thermometer is arranged in a room or region where the heater is arranged), the temperature data of the indoor thermometer is simply used. However, for example, a plurality of room thermometers correspond to one heater (one heater is arranged for a plurality of rooms or areas, and two or more room thermometers are arranged for each room or area. When the minimum room temperature or the maximum room temperature is detected by a plurality of indoor thermometers, the control unit 105 uses the temperature data of the indoor thermometer placed in a room with a large volume to Calculate the temperature difference. That is, the heater to be adjusted is set. At this time, if the air volume is the same, the order described in correspondence with the channels in the unit of FIG. 9, for example, the previously described indoor thermometer is selected as the indoor thermometer using the temperature data.
As described above, when the temperature difference between the rooms is greater than or equal to the set value and a plurality of maximum temperatures or minimum temperatures are detected, the control unit 105 corresponds to the project name and the maximum or minimum temperature is stored from the storage unit 103. Read the air volume of each room, detect the room with the larger air volume and detect the maximum value and the minimum value in the measuring unit placed in the detected large air volume room heater Control the amount of heat generation.

The control unit 105 counts the time from the start of heat generation of each measurement unit, and upon detecting that the time for adjusting the heat generation amount has been reached, obtains a difference in temperature data between the input indoor thermometers, Detect whether or not the difference is greater than or equal to the temperature difference of each room where the heat generation amount control is performed, and if the difference is less than the temperature difference of each room where the heat generation amount control is performed, stop the adjustment control process The adjustment control process is not performed until it is detected that the time of the adjustment interval has elapsed.
On the other hand, the control unit 105 controls the amount of heat generated in each measurement unit when the difference is equal to or greater than the temperature difference between the rooms where the amount of heat generation is controlled.

In addition, when the user sets two or more thermometers (in the setting of the thermometer in the channel of each unit shown in FIG. 9) on the input screen of FIG. When the “prioritize something” check box is selected by an input device such as a mouse, the control unit 105 detects that the priority check box is selected, and the save button is pressed. At this time, the internal storage unit stores together with the other data, the acquisition of the indoor temperature data by the first thermometer of the indoor thermometer in the selection frame of FIG.
That is, when the user checks the check box at the bottom of the display screen in FIG. 17 that the determination of the maximum / minimum room temperature is performed only by the first thermometer, the control unit 105 determines the determination of the maximum or minimum room temperature. Processing is performed when a plurality of room thermometers correspond to one heater, and is used as temperature data for using the difference as the maximum and minimum room temperatures.
On the other hand, when the user checks the check box at the bottom of the display screen that the determination of the maximum / minimum room temperature is performed only with the first thermometer, the control unit 105 has the determination of the maximum or minimum room temperature at the top of the selection frame. Perform at room temperature only. That is, the temperature data of the first indoor thermometer is used to obtain the difference between the indoor thermometers in the order input corresponding to the channels in the unit in FIG.

  In addition, when adjusting the amount of generated heat, the control unit 105 determines that the control value read from the storage unit 103 corresponding to the project name is the maximum value of the heater corresponding to the indoor thermometer having the lowest room temperature, or the highest room temperature. If the heater corresponding to the indoor thermometer has the minimum value (0 W), the heater is not controlled without the heater being controlled ("heater heat generation is maximum" or "heater heat generation is minimum Value (0W) "is added) to the above e-mail address and notified.

Further, as shown in FIG. 1, heat is generated in a configuration in which one indoor thermometer is not associated with one heater and one indoor thermometer is combined with two heaters (or one temperature measurement range). The amount adjustment is described below.
In this configuration, as described above, when the user selects the check box for giving priority to the top of the selection frame on the input screen of FIG. 17 using an input device such as a mouse, the control unit 105 checks the priority. When it is detected that the box is selected and the save button is pressed, the room temperature data is acquired only by the room thermometer at the top of the selection frame in FIG. 9 in the internal storage unit together with other data. Remember that.
At this time, in the measurement unit corresponding to the indoor thermometer having the maximum temperature or the minimum temperature, the control unit 105 has a small output when the adjustment unit is an amount that can adjust the heat generation amount and the heat generation amount of the heater is increased. In the case where the heater is increased for each adjustment unit, while the amount of heat generated by the heater is decreased, control is performed so that the heater having the larger output is decreased for each adjustment unit.

That is, when one indoor thermometer is made to correspond to a plurality of heaters (for example, when a room is large and a plurality of heaters are required from the air volume, or heat energy is supplied to a plurality of rooms), the control unit 105 When increasing the amount of heat output from the heater arranged in the room or region of the lowest temperature, the set adjustment amount of 100 W is divided into units of 50 W, for example, and among the plurality of heaters, the amount of generated heat currently output Increases the amount of heat output from the heater with the smaller. On the other hand, when the calorific value output from the heater arranged in the room or region of the highest temperature is lowered, the set quantity component 100 is divided into, for example, units of 50 W, and among the plural heaters, the calorific value currently output is The amount of heat generated from the larger heater is reduced.
Therefore, the control unit 105 lowers the control value of the heating value of the heater corresponding to the indoor thermometer indicating the maximum temperature by the adjustment unit of the heating value, and the heating value of the heater corresponding to the indoor thermometer indicating the minimum temperature. The control value is increased by the adjustment unit.
As already mentioned, the calorific value given to the whole building needs to be constant in the measurement cycle for measuring each Q value. If the calorific value of any heater is increased, the calorific value of the other heaters Must be reduced to a value similar to the amount of heat generated by any heater.
When the heating value of the heater is controlled, the control unit 105 transmits a control value of the new heating value of the heater to the measurement unit control unit 11, and the measurement unit control unit 11 performs a new control for each measurement unit. Send value.
Thereby, each measurement unit controls the amount of heat generated by each heater with a new control value.

<Analysis Process of Measured Q Value by Q Value Measurement Processing Unit 10>
A case will be described below in which temperature data and set values of thermal energy have already been measured, and analysis data for the measured Q value is created from the project data stored in the storage unit 103.
In the Q value measurement processing unit 10, when the user starts analysis software, the control unit 105 reads out the image data of the operation / display screen for performing the analysis shown in FIG. 18 from the storage unit 103, and reads the read image shown in FIG. Displayed on the display unit 104.
The control unit 105 reads the project name input by the user on the operation / display screen, and reads each data stored corresponding to the project name from the storage unit 103.

When the user presses the building data input button, the control unit 105 detects that the building data input button has been pressed, and the input screen for setting the building data and measuring instrument shown in FIGS. Are sequentially displayed from the storage unit 103, and the data read from the storage unit 103 corresponding to the project name is displayed in the corresponding input field.
Here, when the data input at the time of actual measurement has a correction or is blank, the user overwrites the correction data or newly input data in the corresponding input field and presses the apply button.
When the apply button is pressed, the control unit 105 detects that the apply button has been pressed, and has already been described in “Measurement process of measured Q value by Q value measurement processing unit 10” as data input of each input image. Similar to the processing, the input (or modified) data is written in the storage unit 103 corresponding to the project name.

When it is detected that the input of the correction data and new data in all the input fields in FIGS. 5 to 10 is completed, that is, when it is detected that the apply button in each input image is pressed, the control unit 105 An input screen (not shown) on which buttons for collecting temperature data from the temperature data collecting unit 12 are displayed is displayed.

In addition, the floor area for simple calculation can be set by the user directly entering the actually measured numerical value in the input field.

The simple Q value calculation unit 108 reads the numerical values in the thick input boxes and the shaded input fields for the calculation formulas for calculating the areas of the respective portions of the simple areas of the planes H1 and H2, Substituting into the calculation formula corresponding to the part, the areas of the plane H1 and the plane H2 of each part are obtained, and each of the obtained areas is displayed in the display column of the simple calculation.
The area of each part can also be directly input by the user. Then, for each part, the user selects, using a check box, whether the area of the part directly input, the area of the simple calculation of the plane H1, or the area of the simple calculation of the plane H2 is used for calculating the simple Q value. Can do.

Similarly, with respect to the area of the opening, the simple Q value calculation unit 108 obtains the area of the opening by simple calculation from the floor area of each floor, the height of the floor (distance between the ceiling and the floor), and the ratio of the opening. . In addition, the user can directly input the area of the opening. Then, for each opening, the user can select, using a check box, whether the area of the opening directly input or the area of simple calculation is used for calculation of the simple Q value.
Then, when calculating the simple Q value, the simple Q value calculation unit 108 selects either the area of the directly input opening or the area of the simple calculation that is selected by the check box as the area of each opening. Is used.
Moreover, the numerical value which a user inputs directly into an input column can be used instead of using the result of each simple calculation of the area for each region described above.
When the input process of each data in FIG. 19 is completed, the control unit 105 displays the input screen shown in FIG.

The control unit 105 writes or stores the data input or obtained in FIG. 19 in the building data storage area of the storage unit 103 in association with the project name.
Next, the control unit 105 displays the heat loss coefficient calculation table shown in FIG. 20 on the display unit 104 by pressing the button of the heat loss coefficient calculation table on the input screen of FIG.
In FIG. 20, the simple Q value calculation unit 108 reads the substantial thermal conductivity in each part indicated in each display column of the general part, the material thickness of each part and the thermal conductivity of the material from the storage unit 103, The thermal resistance value (= material thickness / material thermal conductivity) is calculated for each part, calculated as the reciprocal of this thermal resistance, and displayed in the column of the substantial thermal conductivity of each part. As for the thermal conductivity of the material, the correspondence relationship between the material and the thermal conductivity is stored in the storage unit in advance, and the simple Q value calculation unit 108 reads the thermal conductivity corresponding to the material used in each part.

  Then, the simple Q value calculation unit 108 multiplies the area of each part by the coefficient listed in accordance with the classification of the outside air, etc. that contacts the outer periphery of the corresponding part and the above-mentioned actual heat transmissivity, and calculates the heat loss of each part. Calculate and add the calculated heat loss of each part to obtain the total heat loss of the general part. Here, the coefficient Hi is set in advance corresponding to the roof, ceiling, wall, floor, etc., but can be directly input by the user.

  Moreover, the simple Q value calculation part 108 is previously memorize | stored (set) in the memory | storage part 103 corresponding to the heat insulation construction method selected by the term of the underfloor heat insulation of the building outline | summary of FIG. Using the thermal conductivity of the floor between the soil floor and the floor of the basic insulated house (defined in the energy-saving standards for houses), the actual thermal conductivity is taken as the heat loss, and the heat loss of each floor is added to the floor heat loss between the floors. Ask for.

Next, the simple Q value calculation unit 108 reads out the area obtained by the calculation in FIG. 19 from the storage unit 103 and displays it as the area of each opening.
Then, the simple Q value calculation unit 108 calculates the heat corresponding to the material for each opening from the table stored in the storage unit 103 in which the material of the opening is associated with the thermal conductivity corresponding to the material. The through-flow rate is read out, and for each opening, the area of the opening is multiplied by this heat-through-flow rate, the heat loss is calculated, the heat loss of each opening is added, and the total opening heat loss is obtained.
In addition, the simple Q value calculation unit 108 calculates the corrected thermal conductivity of the accessories in each room from the accessories stored in the storage unit 103 in advance and the corrected thermal conductivity per unit area of the accessories. Read the corrected heat flow rate per unit area of the corresponding accessory from the table showing the correspondence, multiply the accessory area by this corrected heat flow rate, calculate the heat loss of the accessory, and calculate the total heat loss at the opening. Add to.

Then, the simple Q value calculation unit 108 reads the numerical value of the Q value air volume input in FIG. 5 from the storage unit 103 and displays it in the ventilation volume column.
Moreover, although the numerical value set beforehand (for example, 0.5) is displayed for the frequency | count of ventilation, a user can input a numerical value directly according to the characteristic of a building. The heat exchange rate on the input screen can also be selected from a plurality of preset numerical values, or the user can directly input the numerical values.
And the simple Q value calculation part 108 calculates the heat loss of ventilation with the following formula | equation.
Ventilation heat loss = 0.35 x air volume x ventilation frequency x (1-heat exchange rate% / 100)

Next, the simple Q value calculation unit 108 adds the total heat loss of the general part, the heat loss of the floor floor, the total heat loss of the opening, and the heat loss of ventilation, and the addition result is the floor of all floors in the building. Divide by the total area value to calculate the Q value, which is the heat loss coefficient of the building, and output this Q value as the calculated Q value.
Here, the simple Q value calculation unit 108 calculates the calculated Q value, but since each part area is calculated internally, it is a simple numerical value without high accuracy, and if each part area is directly input, a normal design is performed. Q value is calculated.
Then, the simple Q value calculation unit 108 displays the calculated Q value in the input field of the calculation Q value on the input screen of FIG. 6 and stores it in the building data storage area of the storage unit 103 in association with the project name. Write and store.
Here, the simple Q value calculation is performed in order to obtain an appropriate heat generation amount of the heater in advance, and if the assumed Q value has deviated greatly, the initial heat generation amount of the heater is insufficient or excessive. Thus, temperature data for measuring the actual Q value cannot be obtained accurately.
However, since the number of measurement days is as long as 4 days or more, it is difficult to measure the Q value again, and when there is no room for calculating the design Q value, simple Q value calculation is performed and it is necessary for actual Q value measurement. An appropriate set value for the heating value of the heater is obtained.

<Calculation processing of measured Q value by Q value calculation unit 107>
The Q value measurement algorithm in this embodiment will be described below.
FIG. 21 shows the difference between the temperature inside the container and the outside temperature increased due to heat generation inside the container due to the thermal resistance of the wall material forming the container as a whole container. It is a conceptual diagram explaining the thermal circuit model which shows that a thermal energy transmits the wall of a container and is discharged | emitted out of a container.
That is, as described above, when one building is made into one room and a heating element with a heating value H is present inside the room as in the thermal circuit shown in FIG. By determining the increase in room temperature (the temperature at which the room temperature of each room in the building is equalized), the phase heat flow resistance R is determined, that is, the heat flow rate of the entire building is determined, and the heat flow rate is calculated as the total floor area of the building. The value divided by is calculated as the Q value.
Here, modeled by the thermal circuit of FIG, applying Kirchhoff's law, the following (1) equation is obtained, a differential equation relating to rt theta _R. The equation (1) is solved under appropriate conditions, and the room temperature step response due to the disturbance θ _E and the room temperature step response due to the heat generation H are obtained.

For example, if the heat generation amount H is constant at time t> 0, such as a step function, dH / dt = 0 on the right side of the above equation (1).
The change in the calorific value is eliminated from the equation, and the following equation (2) is obtained.

Since this differential equation becomes a variable separation type if the disturbance θ _E is constant at time t> 0, θ _R can be solved as in the following equation (3).

In other words, room temperature is considered to be a combination of response to the disturbance (excitation) given to the outside of the wall (excitation) and response to the room heat generation (excitation) (endothermic response). An analytical solution of the partial differential equation of 1) is obtained by Laplace transform, and a solution of a through-flow response and an endothermic response is obtained according to this analytical solution (2).
Here, θ _i = initial room temperature (room temperature at t = 0), R = R ₁ + R ₂ , and λ = 1 / (C · R ₁ ). Furthermore, if the following simple conditions are used, equation (3) becomes a simpler form.
Further, based on the solution of the unit flow-through response, the flow-through response when the excitation is an isosceles triangular wave is obtained by integration or the like. Similarly, based on the solution of the unit endothermic response, the endothermic response when the excitation is a rectangular wave is obtained.
a. When the disturbance is a step function In the equation (3), θ _E = 1, θ _i = 0, and H = 0 are sufficient.
The following expression (4) is a “unit flow response” in the thermal circuit model.

b. When the calorific value is a step function In equation (3), θ _E = 0, θ _i = b ₀ -b, H = 1, R = b ₀ can be used. “Unit endothermic response”.

Next, a prediction formula for room temperature by the response coefficient method will be described.
By using the unit responses given by the equations (4) and (5), the response coefficient φ _i and the heat generation when the disturbance θ _E is an isosceles triangular wave as shown in the following equation (6) are rectangular waves. In this case, the response coefficient ψ is obtained. However, when a response to an isosceles triangular wave is obtained, integration of a unit response or the like is necessary, but the explanation thereof is omitted because it is general. Given the disturbance theta _E Synthesis of a number of isosceles triangle, the disturbance component of the room temperature theta _R is represented by the convolution of the flow response (convolution). Similarly, if room heat generation is considered to be a combination of a large number of rectangular waves, a heat generation component at room temperature is represented by a product of endothermic responses.

In the above equation (6), the suffix j is the order when the time is discretized, and is defined as j = −∞,..., −1, 0,.
In addition, Δt is a time interval at that time (for example, a temperature measurement cycle), and r = e ^−λΔt (one of undetermined counts consisting of a power of a Poisson distribution probability indicating the presence or absence of measurement within the measurement time interval. ). As described above, the room temperature for an arbitrary disturbance and an arbitrary heat generation is obtained by adding the combined product of H and ψ to the combined product of θ _E and φ _i. For example, if the room temperature at t = nΔt) is θR _{, n} , the following equation (7) is obtained. The calorific value H used here is a total value obtained by adding the calorific value measured in each measurement unit for each temperature measurement period.

  By substituting the obtained equation (7) into the equation (6), the equation is transformed into a form that does not include disturbance since the start of measurement (ie, j <0). Further, in consideration of H = 0 when j <0, finally, the disturbance is expressed by the combination of the outside air temperature and the external radiation component as in the following equation (8).

By expressing the outside air temperature and the external radiation component as in the above equation (8), the prediction equation shown in the following equation (9) of the room temperature used in this actual measurement method can be obtained.
In this equation (8), θ ₀ is the outside air temperature (measured by the outside air thermometer 221), Δθ is a value obtained by subtracting the outside air temperature θ ₀ from the measured temperature of the SAT (equivalent outside air) thermometer 220, and a is the external radiation. It is an undetermined coefficient indicating the degree of influence of (sunlight and nighttime radiation).

In the present embodiment, external radiation is handled with the simplest configuration as in the above equation (8), and α is simply defined as a statistically determined coefficient.
That is, the undetermined coefficient is set so that the root mean square of the difference between the predicted room temperature θ _{R, n} and the measured room temperature θ _{R, n} ^* given by the above equation (9) is minimized. Identify (least squares). Here, the average residual δ is expressed by equation (10) as shown below.

Then, the four undetermined coefficients (r, b ₀ , b, a) in Equation (9) are fitted and determined by numerical analysis so that the numerical value of δ shown in Equation (10) is minimized.
However, as can be seen from the equation (9), since r appears as a power here, a method slightly different from a general least square method is used.
The outline of the undetermined coefficient identification method in the present embodiment will be described with reference to the flowchart shown in FIG.
In step S1, room temperature, outside air temperature, and SAT temperature are measured and necessary data is acquired.

  In step S2, the value of r (where 0 <t <1, r is a positive value close to 0 (eg, 0.0001) in the first step, or a value less than 1 close to 1 (0.9999)). )).

Next, in step S3, while calculating the expected room temperature θ ^* by changing the undetermined coefficients (b ₀ , b, a) using equation (9), the average residual δ is calculated using equation (10) in step S4. and three undetermined coefficients using a general least squares method _{(b 0, b,} a) fitting said numerically the undetermined coefficients to obtain the minimum mean residual _{δ (b 0, b, a} ) a Identify.
Then, the average residual δn at this time is output.

In step S5, the average residual δ _n obtained in step S4 is compared with the residual δ _n-1 obtained immediately before. If δn is larger than δn-1, the process proceeds to step S7. if either or smaller .DELTA.n matches .DELTA.n-1, considered as [delta] _n-1 one step before is the minimum, the identification undetermined coefficients at that time as the identification value, the process proceeds to step S6

  In step S7, the numerical value of r is changed by a set numerical value (for example, 0.0001), and the process returns to step S3. For example, when r is a positive numerical value close to 0, the initial value is increased by the above numerical value. On the other hand, when r is a positive numerical value close to 1, the initial value is decreased.

In step S6, using b ₀ identified by shown below (11), calculates a Q value identified by measurement in the field.

  In the above equation (11), A is the total floor area of the building. Further, symbols used in the expressions (1) to (11) are shown below.

The measured Q value obtained by identification as described above is statistical if the actually measured Q value is applied to a phenomenon obtained from a simple heat circuit model as shown in FIG. It is considered that it is interpreted as a numerical value estimated by.
For this reason, there is no mathematical correctness in the Q value in this embodiment, and it is evaluated with the obtained actual Q value how much the identified actual Q value is certain. It is necessary to show.

In the present embodiment, the certainty of the measured Q value is indicated by a ΔQ value. The ΔQ value is the minimum value δ _min in FIG. 22 in which the horizontal axis indicates the Q value and the vertical axis indicates the average residual δ when the Q value is obtained, and is 0.1K larger than this δ _min. A Q value range (Q value change width) having an average residual δ within a numerical value range is obtained as ΔQ. In FIG. 22, the horizontal axis represents the Q value, and the vertical axis represents the average residual δ.
Therefore, this ΔQ value is a numerical value indicating the kurtosis of the Q value in the vicinity of δ _min (coefficient of excess) in the function of the Q value and the residual δ, and the smaller the kurtosis, the more the identification is made. It can be determined that the measured Q value is likely.

As shown in FIG. 22, in order to create a graph showing the change of the average residual δ with respect to the measured Q value, the Q value (that is, b ₀ ) is slightly changed from the identified value, and δ at that time is set to (9) Calculated by the formula. However, when the Q value is changed, an undetermined coefficient (r, b, a) other than b ₀ is calculated and the average residual δ is calculated so that the average residual δ is minimized at the changed Q value. To do.
In the present embodiment, this ΔQ value is used as an index for determining whether or not the measurement period is sufficiently long. That is, the Q value is always assumed within a certain measurement period, but changes with the length of the measurement period. Therefore, there is a problem that if the identification is performed at any time point (measurement period), the measurement period is sufficient and the identification result is likely. Therefore, when the measurement period is gradually lengthened, it is determined that the most probable Q value has been obtained when the ΔQ value has become the minimum, and the Q value is taken as the actually measured Q value.

  2 is recorded in a computer-readable recording medium, and the program recorded in the recording medium is read into a computer system and executed. The measured Q value may be calculated by the above. The “computer system” here includes an OS and hardware such as peripheral devices. The “computer system” includes a WWW system having a homepage providing environment (or display environment). The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Further, the “computer-readable recording medium” refers to a volatile memory (RAM) in a computer system that becomes a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. In addition, those holding programs for a certain period of time are also included.

  The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.
