Description

  The present invention relates to a thermal environment control system and a thermal environment control method.

  For air conditioning equipment installed in each environmental control area (floor, area divided into floors, etc.) of buildings such as buildings, overall control is performed from the building or a remote management room. . Specifically, the administrator of the control room controls the air-conditioning equipment according to the operation plan (thermal environment setting defined in time series) or design specifications that take into account energy conservation measures (CO2 emission reduction, etc.) The thermal environment of each environmental control area is set. If the user (resident) in the environmental control area is dissatisfied with the thermal environment setting set by the administrator, he / she notifies the administrator by telephone or the Internet, etc. Requested a change in settings. In other words, in the conventional thermal environment control in the environmental control area, first, the administrator sets the thermal environment preferentially, then accepts any complaints from the user side and accepts it from the administrator side to set the thermal environment by the administrator side It was catch-ball-like control contents to aim at improvement of.

In addition, there exists a technique disclosed by the patent document 1 shown below as a mechanism which receives a user's request | requirement and aims at the improvement of thermal environment setting, for example. This technology evaluates the thermal feeling and comfort that the air conditioning environment brings to the user based on the air conditioning declaration for the thermal environment from the user, that is, the input data of the sense of “hot” and “cold”, and as an energy saving measure This is a control method for changing the operation setting of the corresponding air conditioner. Furthermore, in this technology, because the user pursues more comfort and there is a possibility that an air conditioning declaration (intentional declaration) that is different from the user's actual feeling may be made, the air conditioning declaration from the user is intentional declaration. It is judged whether it is or not, environmental evaluation close | similar to a user's actual feeling is performed, and the energy saving effect is ensured collectively.

<<< Air-conditioning control that takes into account requests from both managers and users >>>
=== Overview ===
FIG. 4 is a flowchart showing an outline of air conditioning control by the management server 240.
First, the management server 240 satisfies the user's satisfaction (comfort level of thermal environment, productivity) according to the set temperature from the user terminals 102a to 102c for each area which is the minimum unit of the air conditioning control area. The degree information is collected (S400). The collected satisfaction level information is stored in the satisfaction level information DB 246.

Next, the management server 240 analyzes the satisfaction level information for each area stored in the satisfaction level information DB 246 (S401).
Next, the management server 240 analyzes the analysis result of the satisfaction degree information (the production loss cost of the user for each set temperature) and the analysis result of the energy saving reduction amount for each set temperature investigated in advance (the energy for each set temperature). The target value of the control amount (set temperature) of the air conditioning equipment 104a to 104c is calculated based on the cost (S402). The target value is based on the total cost that combines the user's production loss cost for each control amount and the energy cost for each control amount, and suppresses both the user's production loss cost and energy cost in a well-balanced manner. Is a possible value.

  Then, the management server 240 transmits (designates) operation plan information using the calculated control amount target value to the control server 230. As a result, the control server 230 sends a request on the administrator side (energy saving operation) and a request on the user side (comfortable) to the air conditioning equipment 104a to 104c for each area of the office floors 100a to 100c via the air conditioning subsystem 210. It is possible to realize efficient air-conditioning control that simultaneously balances both the degree and productivity (S403).

  The above is the outline of the air conditioning control by the management server 240, and the contents of the steps (S400 to S403) of the flowchart shown in FIG. 4 will be described in detail below.

=== Collecting satisfaction information ===
FIG. 5 is a flowchart showing a flow of processing in which the central monitoring center 200 (Web server 250, management server 240) collects satisfaction level information from users (user terminals 102a to 102c) in each area of the office floors 100a to 100c. It is.

  First, the Web server 250 publishes a Web page (hereinafter referred to as a satisfaction application page) that accepts an application for user satisfaction with respect to the thermal environment of each area on the Internet 50 (S500). FIG. 6 is a diagram showing a relationship between a screen display example of the satisfaction application page and an evaluation value predetermined by the administrator for each satisfaction. The satisfaction application page shown in FIG. 6A adopts the comfort level X as the satisfaction level, and “unsatisfied” is selected as a selection menu (information indicating the comfort level) for extracting the comfort level X of each user. (X = 3), “Slightly dissatisfied (X = 2)”, “Both (X = 1)”, “Somewhat satisfied (X = 0)”, “Satisfied (X = -1) ”and list one of them. The satisfaction application page shown in FIG. 6B employs productivity Y as the satisfaction, and “disturbance” is selected as a selection menu (information indicating productivity) for extracting the productivity Y of each user. "Large (assuming Y = 88)", "I can't concentrate (assuming Y = 91)", "Increase rest (assuming Y = 94)", "I'm interested (assuming Y = 97)", "Problems “None (Y = 100)” is listed, and one of them is applied.

  The user starts up the Web browser software of the user terminals 102a to 102c and browses the satisfaction application page published on the Internet 50 (S501). Then, when applying for the comfort level X and the productivity Y for the current set temperature (S505), the user inputs the personal ID notified in advance from the central monitoring center 200 (S502).

  The management server 240 acquires the personal ID, the comfort level X, and the productivity Y from the user terminals 102a to 102c via the Internet 50 and the Web server 250 (S503). Then, the management server 240 refers to the building characteristic DB 202 to identify the user corresponding to the acquired personal ID, the floor, the zone, and the area to which the user belongs in order (S504), and the acquired comfort level. X and productivity Y are stored in the satisfaction information DB 246 in association with the specified information (S506).

  The satisfaction information DB 246 stores the satisfaction information for a total of 60 minutes corresponding to a plurality of set temperatures until a total of 60 minutes elapses every 10 minutes (S507, S508). ). FIG. 7 is a diagram showing the content of the satisfaction information table 248 stored in the satisfaction information DB 246 as described above. In the figure, for example, users A, B, and C belong to area 1, and comfort level X and productivity Y applied by each user A to C are set at the time of application at intervals of 10 minutes. It is stored in association with the temperature T.

=== Analysis of satisfaction information ===
FIG. 8 is a flowchart showing the analysis processing of the satisfaction level information stored in the satisfaction level information DB 246 by the management server 240.

  First, the management server 240 calculates an area-specific dissatisfaction level fX (%) for each area based on the comfort level X stored in the satisfaction level information DB 246 (S801). Specifically, first, for each area, according to the following formulas (1a) to (1f), the time series dissatisfaction degree 10, which is the total result of the comfort level X 10 minutes before, 60 minutes before A time-series dissatisfaction level 60, which is the total result of the comfort level X, is calculated.

Time series dissatisfaction 10 = 0.4 × (k′X ′ + k ″ X ″ + k ′ ″ X ′ ″ +...) (1a)
Time series dissatisfaction 20 = 0.2 × (k′X ′ + k ″ X ″ + k ′ ″ X ′ ″ +...) (1b)
Time series dissatisfaction 30 = 0.1 × (k′X ′ + k ″ X ″ + k ′ ″ X ′ ″ +...) (1c)
Time series dissatisfaction 40 = 0.1 × (k′X ′ + k ″ X ″ + k ′ ″ X ′ ″ +...) (1d)
Time series dissatisfaction 50 = 0.1 × (k′X ′ + k ″ X ″ + k ′ ″ X ′ ″ +...) (1e)
Time series dissatisfaction 60 = 0.1 × (k′X ′ + k ″ X ″ + k ′ ″ X ′ ″ +...) (1f)

In the above formulas (1a) to (1f), numerical values (0.4, 0.2, 0.1, 0.1, 0.1, 0.1) to be multiplied with the sum in parentheses. ) Represents a time coefficient t, and each element in parentheses represents a value obtained by multiplying the comfort factor X of each user by the officer coefficient k. Note that the time coefficient t increases the weight of the latest time for the purpose of suppressing the influence of the past comfort level X in consideration of the user's environmental habituation over time. The officer coefficient k is weighted in consideration of the user's position and role in the area. Then, as shown in the following equation (2), an average value from the time series dissatisfaction degree 10 to the time series dissatisfaction degree 60 is obtained, and the average value is calculated as an area-specific dissatisfaction degree fX (%) for each comfort level X. To do.
Dissatisfaction level by area fX (%) = (Time series dissatisfaction degree 10 + Time series dissatisfaction degree 20 + ... Time series dissatisfaction degree 60) / (Σ (k × 3 (comfort degree in case of dissatisfaction)))) ( 2)

  The calculation of the dissatisfaction level fX (%) by area using the equations (1a) to (1f) and (2) is repeatedly executed every 10 minutes. FIG. 9A is a diagram illustrating a calculation example of the dissatisfaction level fX (%) according to the area by the comfort level X using the formulas (1a) to (1f) and (2). FIG. 9A shows an area to be calculated, and the time series dissatisfaction degree 10 to 60 is based on the application results of the comfort level X every 10 minutes from the three users A to C (2.8). , 0.8, 0.3, 0.3, 0.3, 0.3), and by averaging the obtained time-series dissatisfaction degrees 10 to 60, the dissatisfaction degree by area fX is 53.3 ( %).

The area-specific dissatisfaction fY (%) for each area related to the productivity Y can be calculated in the same manner as the area-specific dissatisfaction fX (%) for each area related to the comfort level X. Specifically, first, for each area, according to the following formulas (3a) to (3f), the time series dissatisfaction degree 10 that is the result of counting the productivity Y 10 minutes before, 60 minutes before The time series dissatisfaction 60, which is the total result of the productivity Y, is calculated.
Time series dissatisfaction 10 = 0.4 × (k′Y ′ + k ″ Y ″ + k ′ ″ Y ′ ″ +...) (3a)
Time series dissatisfaction 20 = 0.2 × (k′Y ′ + k ″ Y ″ + k ′ ″ Y ′ ″ +...) (3b)
Time series dissatisfaction 30 = 0.1 × (k′Y ′ + k ″ Y ″ + k ′ ″ Y ′ ″ +...) (3c)
Time series dissatisfaction 40 = 0.1 × (k′Y ′ + k ″ Y ″ + k ′ ″ Y ′ ″ +...) (3d)
Time series dissatisfaction 50 = 0.1 × (k′Y ′ + k ″ Y ″ + k ′ ″ Y ′ ″ +...) (3e)
Time series dissatisfaction 60 = 0.1 × (k′Y ′ + k ″ Y ″ + k ′ ″ Y ′ ″ +...) (3f)

Then, as shown in the following equation (4), an average value from the time series dissatisfaction degree 10 to the time series dissatisfaction degree 60 is obtained, and the average value is calculated as an area-specific dissatisfaction degree fY (%) for each area related to the productivity Y. To do.
Dissatisfaction by area fY (%) = (Time series dissatisfaction degree 10 + Time series dissatisfaction degree 20 + ... Time series dissatisfaction degree 60) / (Σ (k × 100 (productivity when there is no problem)))) (4)

  The calculation of the dissatisfaction level fY (%) by area using the equations (3a) to (3f) and (4) is repeatedly executed every 10 minutes. FIG. 9B is a diagram illustrating a calculation example of the dissatisfaction level fY (%) according to the area by the productivity Y using the formulas (3a) to (3f) and the formula (4). FIG. 9B shows an area to be calculated, and time series dissatisfaction degrees 10 to 60 based on the application results of productivity Y every three minutes from three users A to C (156, 78), respectively. 39, 39, 39, 39), and by averaging the obtained time-series dissatisfaction degrees 10 to 60, the area-specific dissatisfaction degree fX is found to be 97.5 (%).

  The area-specific dissatisfaction levels fX and fY for each area calculated as described above are stored in the zone-specific evaluation map DB 248 in order to generate a zone evaluation map described later.

  Next, the environment server 230 totals the dissatisfaction levels fX and fY for each area, generates a satisfaction evaluation map for each zone (S802), and stores it in the evaluation map DB 248 for each zone (S803). FIG. 10 is a diagram showing an example of the zone-specific evaluation map. The evaluation map for each zone shown in the figure represents the dissatisfaction fX and fY for each area in the interior and perimeter of each zone in the form of a bar graph. According to the zone-specific evaluation map, for example, an area-specific dissatisfaction level of 50% is set as a threshold, and an area in the floor where the area-specific dissatisfaction exceeds the threshold can be easily identified.

=== Calculation of control amount target value ===
The management server 240 calculates the production loss according to the degree of dissatisfaction of the user based on the degree of dissatisfaction fX and fY according to the area corresponding to the set temperature for each area stored in the zone-specific evaluation map DB 248.

  Specifically, the dissatisfaction degree (%) information for each set temperature (° C.) according to the analysis result of the satisfaction degree information shown in FIG. 11A and the user as shown in FIG. By associating information on production loss (%) such as a decrease in thinking ability for each degree of dissatisfaction (%), user production loss for each set temperature (° C.) as shown in FIG. (%) Information is calculated. Note that the information shown in FIG. 11B may be a well-known result published by an academic society or the like, or an analysis result of a prior questionnaire survey.

  Alternatively, using the information on the user productivity (%) for each set temperature (° C.) according to the analysis result of the satisfaction degree information shown in FIG. 12A, the set temperature shown in FIG. Information on production loss (%) for each (° C) may be directly calculated. The production loss of the user can be obtained by subtracting the productivity of the applied user from the maximum productivity of 100%.

  Next, the management server 240 calculates a total cost that combines the production loss cost for each set temperature calculated as described above and the energy cost determined in advance for each set temperature. The energy cost means the energy cost consumed by the outside air condition, the air conditioning method, and the room temperature set temperature. Then, the management server 240 calculates a set temperature target value based on the calculated total cost.

  Specifically, by totaling (for example, simply adding) the production loss cost for each set temperature shown in FIG. 13 (a) and the energy cost for each set temperature shown in FIG. 13 (b). The total cost for each set temperature shown in FIG. More specifically, according to FIG. 13 (a), it can be seen that the production loss cost increases as the set temperature becomes higher than a certain temperature band or as the set temperature becomes lower than a certain temperature band. According to (b), it can be seen that, for example, during cooling, the energy cost is reduced as the set temperature increases. Thus, since there is a range where the relationship between the production loss cost with respect to the set temperature and the relationship with the energy cost with respect to the set temperature are contradictory, the total cost with respect to the set temperature is It becomes a convex function. Therefore, the set temperature at which the total cost is minimized is adopted as a target value that can satisfy both the administrator's request (energy saving operation) and the user's request (comfort level, productivity) in a balanced manner at the same time. can do. It should be noted that various optimization algorithms such as a local search method, a steepest descent method, or a heuristic method can be employed in calculating the set temperature when the total cost is minimized.

=== Air conditioning control based on target value ===
FIG. 14 is a flowchart showing the air conditioning control process of the control server 230 based on the target value designated by the management server 240.

  First, the control server 230 acquires a set temperature target value for each area from the management server 240 (S1400). The acquisition of the target value is obtained as operation plan data including a change permission flag and upper and lower limit values stored in the building characteristic DB 242. Next, the control server 230 detects the current temperature in the area by a temperature sensor arranged for each area or each zone (not shown). Then, the target value of the set temperature is changed based on the deviation between the detected temperature in the area and the target value of the set temperature by the existing air conditioning control (feedback control) (S1401).

  Next, the control server 230 identifies whether or not the target value of the set temperature should be changed based on the change permission flag. If the control server 230 recognizes that the target value can be changed, the changed target value indicates the upper and lower limit values. It is determined whether or not to deviate (S1402). If it deviates from the upper and lower limit values (S1403: YES), the target value before the change is determined (S1404), and if it does not deviate from the upper and lower limit values (S1403: NO), the target value after the change is determined. Confirm (S1403). Then, the control server 230 controls the air conditioning equipment 104a to 104c of the office floors 100a to 100c via the air conditioning subsystem 210 based on the determined target value (S1405).

  As described above, according to the BA system 10, the target value of the control amount obtained based on the total cost obtained by integrating the production loss cost of the user according to the control amount and the energy cost according to the control amount is used for environmental control.
