First, the outline of the present invention will be described with reference to FIG.
The air conditioning control system and the air conditioning control method according to the present invention automatically control the set temperature, air volume, and wind direction of the air conditioner based on the operation history (change history of the set temperature) of the user.

  In general, a user of an air conditioner increases the set temperature of the air conditioner when it feels “too cold” and lowers the set temperature when it feels “too hot”. However, instead of immediately changing the set temperature when the user feels it is “too cold” or “too hot”, the user does not change the set temperature for a certain period of time, change.

  In the present invention, the time until the set temperature is changed is used. Specifically, the temperature environment of the target area is monitored based on the intake air temperature, etc., and when the temperature environment becomes uncomfortable for the user, the set temperature is not changed immediately but set after a time delay. Change the temperature. Thereby, in addition to the improvement of the comfort by automatic control, the preference for each of a plurality of users can be compromised in a time division manner, and the power consumption can be reduced.

  FIG. 1 shows, for example, the average of the time until the set temperature is changed from the operation history (2011/8/22 to 2011/9/16) for the actual summer of the building for 4 weeks, by the intake air temperature. Results are shown. Here, the intake air temperature and the room temperature are synonymous with each other.

  In FIG. 1, in this example, the user changes the set temperature after 110 minutes on average after the room temperature becomes 27 ° C. or higher. That is, it can be said that after the room temperature became 27 ° C. or higher, it was too hot in an average of 110 minutes to withstand.

  In the present invention, the room temperature is monitored based on the average time until the set temperature is changed. In this example, the room temperature of 27 ° C. or higher is 110 × d minutes (d is a value less than 1 (for example, 0.9)). When it continues as described above, control is performed to automatically lower the set temperature by 1 ° C. Thus, comfort can be improved by automatically changing the set temperature before the user becomes uncomfortable.

  Conversely, similar control is performed even when the room is too cold. In this example, when 38 × d minutes have elapsed since the room temperature became 26 ° C. or lower, control is performed to automatically raise the set temperature by 1 ° C. Thereby, even if it is a case where an excessive temperature setting is made by the user, it is possible to control the set temperature within a range that does not cause discomfort.

Next, the effects of the present invention will be summarized below.
First, by automatically changing the set temperature before the user becomes uncomfortable and unbearable, comfort can be improved with high operability.

  In addition, by automatically controlling the set temperature in the range of ± 1 ° C prior to the user's operation, for example, if it is too hot, it prevents excessive change of the set temperature, such as drastically reducing the set temperature. Electric power can be reduced.

  In this example, it can be seen that there are users who are too hot at a set temperature of 27 ° C. and users who are too cold at a set temperature of 26 ° C. In the present invention, in response to these conflicting requirements, Control that the set temperature is lowered by 1 ° C. when the room temperature remains at 27 ° C. for 110 × d minutes, and then the set temperature is raised by 1 ° C. and the room temperature is raised to 27 ° C. when the room temperature remains at 26 ° C. for 38 × d minutes By repeating the above, the preferences of a plurality of users can be reflected in a time division manner.

  Hereinafter, preferred embodiments of an air conditioning control system and an air conditioning control method according to the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts will be described with the same reference numerals.

Embodiment 1 FIG.
FIG. 2 is a block diagram showing an air conditioning control system according to Embodiment 1 of the present invention. In FIG. 2, the air conditioning control system includes an air conditioning control unit 10 and an air conditioner 20. The air conditioning control unit 10 includes an operation history storage unit 11, a temperature history storage unit 12, a totalization processing unit 13, a control processing unit 14, and a totalization processing table storage unit 16.

  The operation of the air conditioning control system according to the first embodiment of the present invention is roughly divided into a totaling process by the totaling processing unit 13 and a control process by the control processing unit 14. The aggregation process is a process that is performed before the air conditioning control unit 10 controls the air conditioner 20, and the control process is a process in the middle of the air conditioning control unit 10 controlling the air conditioner 20.

  In the air conditioning control system according to Embodiment 1 of the present invention, before the air conditioning control unit 10 actually performs the air conditioning control, the average time until the set temperature is changed is totaled, and the discomfort resistant time as shown in FIG. It is necessary to create an aggregation processing table related to

  In the tabulation processing, for example, a tabulation processing table is created and stored in the tabulation processing table storage unit 16 based on data for about two weeks before operating the air conditioning control system. If the season (summer or winter) and the users in the area covered by the air conditioner 20 are almost the same, the larger the number of data, the better, for example, the data for the same month in the previous year, etc. May be used.

  The control process monitors the room temperature during operation of the air conditioner 20 using the tabulation process table created in the tabulation process as an input. If the room temperature at which the user feels uncomfortable continues for a certain time or longer, the control process automatically To change.

First, the aggregation process by the aggregation processing unit 13 will be described in detail.
In order to perform the aggregation process, first, the operation history of the set temperature of the air conditioner 20 and the temperature history of the room temperature for a specific period such as data for about two weeks before the air conditioning control system is operated and data for the same month of the previous year. And need to get. Here, the operation history of the set temperature is stored in the operation history storage unit 11 as operation history data every time the set temperature is changed.

  As the room temperature, temperature information used by the air conditioning control unit 10 to control the air conditioner 20 such as the intake air temperature (intake air temperature) of the air conditioner 20 or the temperature measured by the temperature sensor of the remote controller is used. Here, a case where the intake air temperature is used will be described. Further, it is assumed that the intake air temperature is stored in advance in the temperature history storage unit 12 as temperature history data before operating the air conditioning control system. The data sampling period at this time is T.

  In the aggregation process, the operation history data and the temperature history data are input, the average time until the set temperature is changed is aggregated, and an aggregation process table is created. Further, the counting process is further divided into a process for calculating the discomfort time when it is too hot and a process for calculating the discomfort time when it is too cold. Note that when the operation history data and the temperature history data are collectively referred to, they are simply referred to as history data.

  First, with respect to the history data illustrated in FIG. 3, a counting process for calculating the discomfort time when the counting processing unit 13 is too hot will be described with reference to the flowchart shown in FIG. 4. FIG. 5 shows a totaling process table (including the UP direction described later) created by the totaling process shown in FIG.

The totalization processing unit 13 acquires operation history data and temperature history data of the air conditioner 20 (step S1).
Then, the aggregating part 13, at time _{t cur,} it substitutes the first time in the history data (step S2). Thereby, a loop is started.

Next, the totalization processing unit 13 searches for a time (hereinafter referred to as “time t _change ”) at which the temperature is first lowered after the time t _cur (step S <_{b> 3} ). In the example of FIG. 3, the time “11:20” of the operation history data 201 corresponds to this.

Subsequently, the totalization processing unit 13 determines whether or not there is a history of lowering the set temperature after the time _tcur (step S4).

If it is determined in step S4 that there is a history of lowering the set temperature (that is, No), the aggregation processing unit 13 discards the intake air temperature at the measurement time immediately before the time t _change (truncates the decimal point, hereinafter “ Temperature (referred to as temperature Temp _change ) (step S5). In the example of FIG. 3, the temperature “28.1 ° C.” of the temperature history data 202 one cycle (T) before the operation history data 201 corresponds to this, and the temperature Temp _change is 28 ° C.

Next, the totalization processing unit 13 calculates a time (uncomfortable time) from when the temperature Temp _change is reached until the user changes undesirably and changes the set temperature (steps S6 and S7).

Specifically, the aggregation processing unit 13 acquires the time t _begin before the time t _change and finally the intake air temperature was lower than the temperature Temp _change by scanning the history data in the forward direction (step S6). In the example of FIG. 3, the time “10:25” of the temperature history data 203 at which the intake air temperature was less than 28 ° C. before the time 11:20 of the operation history data 201 corresponds to the time t _begin .

Subsequently, the totalization processing unit 13 calculates the discomfort resistance time by (t _change −t _begin ) (step S <b> 7). In the example of FIG. 3, it is 55 minutes from 10:25 to 11:20.

Next, the totalization processing unit 13 stores the intake air temperature Temp _change and the unpleasant time (t _change -t _begin ) in the temporary storage area (step S8). In the example of FIG. 3, information “28 ° C., 55 minutes” is stored in the temporary storage area.

Subsequently, the aggregation processing unit 13 substitutes the time t _change for the time t _cur (step S9). This terminates the loop. That is, the processes of steps S3 to S9 are repeated until it is determined in step S4 that there is no history of lowering the set temperature (that is, Yes).

  In the example of FIG. 3, since there is operation history data 204 in which the set temperature is lowered following the operation history data 201, similarly, the intake air temperature immediately before that (28 ° C., rounded down to the nearest decimal point) and uncomfortable time ( Before the operation history data 204, and finally from the time “14:50” of the temperature history data 206 when the intake air temperature was less than 28 ° C. to the time “15:30” of the operation history data 204 40 minutes) is further detected, and information “28 ° C., 40 minutes” is stored in the temporary storage area. Thereafter, the same processing is repeated as long as the data continues, and when the data ends, the loop ends.

  If it is determined in step S4 that there is no history of lowering the set temperature (that is, Yes), the aggregation processing unit 13 determines the time until the set temperature stored in the primary storage area is changed in step S8. Are calculated for each intake air temperature, and an average value is calculated for each (step S10).

The result of step S10 is stored in the format shown in the tabulation processing table of FIG. In other words, for each intake air temperature, an average value of the anti-discomfort time (t _change -t _begin ) is calculated and stored in the change time column. Also, “DOWN” is stored in the change direction column.

  Further, with respect to the history data illustrated in FIG. 3, a counting process for calculating the discomfort time when the counting processing unit 13 is too cold will be described with reference to the flowchart shown in FIG. 6. The aggregation process table (including the DOWN direction) created by the aggregation process shown in FIG. 6 is as shown in FIG.

Here, in the counting process shown in FIG. 6, instead of step S3, the counting processing unit 13 searches for a time t _change when the temperature is first raised after time t _cur (step S3a).
Further, the tally processing unit 13 determines whether or not there is a history of increasing the set temperature after time t _cur instead of step S4 (step S4a).

Further, the tally processing unit 13 acquires the intake air temperature Temp _change (rounded up after the decimal point) at the measurement time immediately before the time t _change instead of step S5 (step S5a).
Further, instead of step S6, the aggregation processing unit 13 scans the history data in the forward direction at time t _begin before the time t _change and finally at the time t _begin when the intake air temperature is higher than the temperature Temp _change. Obtain (step S6a).
Note that the result of step S10 is stored as “UP” in the change direction column.

  Further, at this time, there may be a case where there are both a history of lowering the set temperature and an increased history of the same intake air temperature. In this case, in order to perform control uniquely, only the one with the larger number of times on the history data is used. Here, if the number of times is the same on the history data, the control is not performed when the intake air temperature is reached, and the row of the intake air temperature is deleted from the totalization processing table.

Next, the control processing by the control processing unit 14 will be described in detail with reference to the flowchart shown in FIG.
The control process is performed with the average time until the set temperature is changed, which is shown in the tabulation process table of FIG. In the control process, an elapsed time table shown in FIG. 8 is used. This elapsed time table is a table that stores how many minutes have passed since the intake air temperature is equal to or higher than each intake air temperature. A unique row is provided for all intake air temperatures that can be measured by the air conditioner 20 to be controlled. It is an existing table.

First, the control processing unit 14 initializes all the values in the column of elapsed time to 0 minutes on the elapsed time table of FIG. 8 (step S11).
The control processing unit 14 repeats the following steps S12 to S23 with a period T (minutes) (first loop).

Subsequently, the control processing unit 14 acquires the current intake air temperature (step S12). The intake air temperature at this time is defined as temperature Temp _now .

Next, the control processing unit 14 acquires one row of the tabulation processing table in FIG. 5 (Step S13). Hereinafter, the row number of this row is row i, the intake air temperature is temperature Temp _i , the average discomfort time is time t _i , and the change direction is direction dir.

Subsequently, the control processing unit 14 acquires a row where the intake air temperature is equal to Temp _i from the elapsed time table of FIG. 8 (step S14). Hereinafter, the row number of this row is assumed to be row j.
Next, the control processing unit 14 compares the temperature Temp _now , the temperature Temp _i, and the direction dir (step S15).

In Step S15, when Temp _now ≧ Temp _i and dir = “DOWN”, the control processing unit 14 increases the value of the column of the elapsed time in row j by the period T on the elapsed time table of FIG. (Step S16). The value after the increase is defined as time t _j .

Subsequently, the control processing unit 14 determines whether or not t _j ≧ t _i × d (step S17). Here, d indicates a parameter less than 1. By setting d to a value such as 0.9, for example, the set temperature can be changed prior to the user's operation as described above.

In step S17, a _{t j} ≧ _{t i} × d (i.e., Yes) and when it is determined, the control processor 14, the set temperature of the air conditioner 20 is lowered 1 ° C. (step S18), and step S11 Migrate to
On the other hand, if it is determined in step S17 that t _j ≧ t _i × d is not satisfied (that is, No), the process proceeds to step S23.

In Step S15, if Temp _now ≦ Temp _i and dir = “UP”, the control processing unit 14 sets the value of the column of elapsed time in the row j on the elapsed time table of FIG. (Step S19). The value after the increase is defined as time t _j .

Subsequently, the control processing unit 14 determines whether or not t _j ≧ t _i × d (step S20).

In step S20, a _{t j} ≧ _{t i} × d (i.e., Yes) and when it is determined, the control processor 14 is a set temperature of the air conditioner 20 increased 1 ° C. (step S21), and step S11 Migrate to
On the other hand, if it is determined in step S20 that t _j ≧ t _i × d is not satisfied (that is, No), the process proceeds to step S23.

In step S15, in cases other than the above (for example, during hunting), the control processing unit 14 updates the value of the column of the elapsed time in row j to 0 on the elapsed time table in FIG. Step S22).
The control processing unit 14 repeats the processing of steps S13 to S22 for all rows included in the tabulation processing table of FIG. 5 (second loop) (step S23).

  Next, as a specific operation of the control processing unit 14, a case where the control processing is performed on the operation history data and the temperature history data illustrated in FIG. 9 based on the aggregation processing table shown in FIG. Moreover, the change of the elapsed time table at this time is shown in FIG. Here, the calculation is performed with the parameter d = 0.8.

  First, when the control process is started at 10:00, all the elapsed time tables in the initial state are zero. Thereafter, since the intake air temperature is 28 ° C. or higher, the elapsed time in the row of the intake air temperature 28 ° C. in the elapsed time table starts to be added (point 901 in FIGS. 9 and 11). At this time, no addition is made for rows at 27 ° C., 26 ° C., and 25 ° C. These temperatures are specified in the change direction UP in the totalization processing table, that is, they are too cold, so when they fall below, the elapsed time is added and used as a reference for raising the set temperature.

  Subsequently, at 10:20, the intake air temperature becomes 29 ° C. or higher. In this case, since it is 28 ° C. or higher and 29 ° C. or higher, the elapsed time is added to both the row of the intake air temperature 28 ° C. and the row of 29 ° C. in the elapsed time table (point 902 in FIGS. 9 and 11).

  After that, at 10:35, the elapsed time of the 29 ° C. row of the elapsed time table becomes 20 minutes (point 903 in FIGS. 9 and 11). As a result, the elapsed time becomes an average discomfort time 20 minutes × 0.9 = 18 minutes or more in the 29 ° C. row of the tabulation processing table, so that the set temperature is controlled to be lowered by 1 ° C. When the control is performed, the value of the elapsed time table is reset once.

  Even after 10:40 after the control, the temperature of 28 ° C. or higher still continues, so the 28 ° C. row of the elapsed time table starts to be added again (at 904 in FIGS. 9 and 11).

  Subsequently, at 11:30, the elapsed time of the 28 ° C. row of the elapsed time table becomes 55 minutes (point 905 in FIGS. 9 and 11). As a result, the elapsed time becomes equal to or greater than 60 minutes × 0.9 = 54 minutes in the average discomfort time of the row of 28 ° C. in the tabulation processing table, so that the set temperature is controlled to be lowered by 1 ° C. When the control is performed, the values of the elapsed time table are once reset to 0 (at time 906 in FIGS. 9 and 11).

  Thereafter, the elapsed time transitions without being added, but at 12:00, the intake air temperature becomes 27 ° C. or less, so the elapsed time in the row of the intake air temperature 27 ° C. in the elapsed time table starts to be added ( (Time 907 in FIGS. 9 and 11).

  At 12:50, the elapsed time of the 27 ° C. row in the elapsed time table is 55 minutes, and the average discomfort time is 60 minutes × 0.9 = 54 minutes or more. Is performed (at time 908 in FIGS. 9 and 11). When the control is performed, the value of the elapsed time table is reset once (at 909 in FIGS. 9 and 11).

  After this, the elapsed time table remains 0, but at 14:40, since the intake air temperature is 28 ° C. or higher, the elapsed time in the row of the intake air temperature 28 ° C. in the elapsed time table starts to be added (FIG. 9 and 11, 910).

  However, after that, since the intake air temperature again returns to less than 28 ° C., in this case, the 28 ° C. row of the elapsed time table is reset to 0 when it becomes less than 28 ° C. (time 911 in FIGS. 9 and 11). ).

  In the above specific example, cooling in summer has been described, but the same algorithm can be applied to heating in winter. In this case, since the amount of clothes is different between the summer and winter, the unpleasant temperature is considered to be different. For this reason, control is performed by creating separate tabulation results for the summer and winter seasons.

  In addition, when the number of changes in the set temperature of the user at a specific intake air temperature is less than a certain number of times in a certain period (such as an operation that is performed only once a week), it is an irregular operation. It is possible to ignore it without performing the aggregation process.

As described above, according to the first embodiment, the operation history storage unit that stores the change history of the set temperature for the air conditioner by the user as the operation history data, and the temperature information that the air conditioning control unit uses to control the air conditioner. Temperature history storage unit that stores the history of temperature as temperature history data, and based on the operation history data and temperature history data, the average time until the set temperature is changed by the user is aggregated for each temperature, and the aggregation processing table Control processing to change the set temperature of the air conditioner in a time shorter than the average time until the set temperature is changed by the user by monitoring the temperature information based on the total processing unit that creates and the total processing table Department.
Therefore, while improving comfort with high operability, it is possible to reduce power consumption and reflect the preferences of a plurality of users.

Embodiment 2. FIG.
In the air conditioning control system according to Embodiment 2 of the present invention, in addition to the control of Embodiment 1 described above, control of the air volume and direction is attempted before the set temperature is changed. Here, it is assumed that the air conditioner 20 can change the wind direction into three stages of horizontal, diagonal, and immediately below, and can set the swing operation. In addition, the air conditioner 20 can change the air volume in two stages of “strong” / “weak”.

  Of the operations of the air-conditioning control system according to Embodiment 2 of the present invention, the aggregation processing by the aggregation processing unit 13 is the same as that shown in the first embodiment, and therefore the control processing by the control processing unit 14 will be described below. To do.

The control processing by the control processing unit 14 will be described in detail with reference to the flowchart shown in FIG.
The control process is performed with the average time until the set temperature is changed, which is shown in the tabulation process table of FIG. In the control process, the elapsed time table shown in FIG. 8 is used as in the first embodiment. Further, after the control, in order to restore the setting of the air volume and the air direction, the last air volume and the air direction manually set by the user (not set by the control processing unit 14) are stored in the air conditioning control unit 10. Shall.

  The operation of the control processing unit 14 according to the second embodiment of the present invention is substantially the same as that of the first embodiment. In the case of the cooling operation, before step S18 of FIG. Before step S21 in FIG. 7, an air volume / wind direction control process shown in the flowchart of FIG. 13 to be described later is inserted.

First, the control processing unit 14 initializes all the values in the column of elapsed time to 0 minutes on the elapsed time table of FIG. 8 (step S11).
The control processing unit 14 repeats the following steps S12 to 23 and 31 to 34 at a cycle T (minutes) (first loop).

Subsequently, the control processing unit 14 acquires the current intake air temperature (step S12). The intake air temperature at this time is defined as temperature Temp _now .

Next, the control processing unit 14 acquires one row of the tabulation processing table in FIG. 5 (Step S13). Hereinafter, the row number of this row is row i, the intake air temperature is temperature Temp _i , the average discomfort time is time t _i , and the change direction is direction dir.

Subsequently, the control processing unit 14 acquires a row where the intake air temperature is equal to Temp _i from the elapsed time table of FIG. 8 (step S14). Hereinafter, the row number of this row is assumed to be row j.
Next, the control processing unit 14 compares the temperature Temp _now , the temperature Temp _i, and the direction dir (step S15).

In Step S15, when Temp _now ≧ Temp _i and dir = “DOWN”, the control processing unit 14 increases the value of the column of the elapsed time in row j by the period T on the elapsed time table of FIG. (Step S16). The value after the increase is defined as time t _j .

Subsequently, the control processing unit 14 determines whether or not t _j ≧ t _i × d1 (step S31). Here, d1 indicates a parameter less than 1. By setting d1 to a value such as 0.9, for example, as described above, the set temperature can be changed prior to the user's operation.

If it is determined in step S31 that t _j ≧ t _i × d1 (that is, Yes) and the cooling operation is being performed, the control processing unit 14 executes an air volume / wind direction control process described later. (Step S32), the process proceeds to step S18.

If it is determined in step S31 that t _j ≧ t _i × d1 (that is, Yes) and the heating operation is being performed, the control processing unit 14 proceeds to step S18 as it is.
On the other hand, if it is determined in step S31 that t _j ≧ t _i × d1 is not satisfied (that is, No), the process proceeds to step S23.

In step S18, when the air volume / wind direction control process ends after elapse of t _i × d2 or when the air volume / air direction control process is not executed, the control processing unit 14 decreases the set temperature of the air conditioner 20 by 1 ° C. The process proceeds to step S11. When the air volume / winding direction control process is ended by an operation by the user, the control processing unit 14 proceeds to step S11 without changing the set temperature. Here, d2 is a parameter.

In Step S15, if Temp _now ≦ Temp _i and dir = “UP”, the control processing unit 14 sets the value of the column of elapsed time in the row j on the elapsed time table of FIG. (Step S19). The value after the increase is defined as time t _j .

Subsequently, the control processing unit 14 determines whether or not t _j ≧ t _i × d1 (step S33).

In step S33, when it is determined that t _j ≧ t _i × d1 (that is, Yes) and the heating operation is being performed, the control processing unit 14 performs an air volume / wind direction control process described later. (Step S34), the process proceeds to Step S21.

If it is determined in step S33 that t _j ≧ t _i × d1 (ie, Yes) and the cooling operation is being performed, the control processing unit 14 proceeds to step S18 as it is.
On the other hand, if it is determined in step S33 that t _j ≧ t _i × d1 is not satisfied (that is, No), the process proceeds to step S23.

In step S21, when the air volume / wind direction control process ends after elapse of t _i × d2 or when the air volume / air direction control process is not executed, the control processing unit 14 increases the set temperature of the air conditioner 20 by 1 ° C. The process proceeds to step S11. When the air volume / winding direction control process is ended by an operation by the user, the control processing unit 14 proceeds to step S11 without changing the set temperature.

In step S15, in cases other than the above (for example, during hunting), the control processing unit 14 updates the value of the column of the elapsed time in row j to 0 on the elapsed time table in FIG. Step S22).
The control processing unit 14 repeats the processing of steps S13 to 22, 31 to 34 for all rows included in the tabulation processing table of FIG. 5 (second loop) (step S23).

Next, the air volume / wind direction control processing by the control processing unit 14 will be described with reference to the flowchart shown in FIG. Note that the control processing unit 14 may control only one of the air volume and the wind direction.
First, the control processing unit 14 stores the current air volume and direction in order to restore the air volume and direction after the control (step S41).

Subsequently, the control processing unit 14 sets the air volume to “strong” (step S42).
Next, the control processing unit 14 changes the wind direction (step S43). Here, when the original wind direction is horizontal, the swing operation is changed, and in other cases, the wind direction is changed directly below.

Subsequently, the control processing unit 14 acquires the current time (step S44). The time at this time is assumed to be time t _start .
In addition, the control processing unit 14 repeats the processes of the following steps S45 to 47 from this point until a predetermined time elapses or an operation by the user is performed.

Next, the control processing unit 14 determines whether or not the setting has been changed by the user (step S45).
If it is determined in step S45 that the setting has not been changed (that is, No), the control processing unit 14 acquires the current time (step S46). The time at this time is defined as time t _now .

Subsequently, the control processing unit 14 _(or a _{t now -t start ≧ t i ×} d2) loop or elapsed _{t i} × d2 or more from the start determines whether (step S47).
If it is determined in step S47 that t _i × d2 or more has not elapsed (ie, No), the process loops and proceeds to step S45.

On the other hand, if it is determined in step S45 that the setting has been changed (that is, Yes), and if it is determined in step S47 that more than t _i × d2 has elapsed (that is, Yes), the control processing unit 14 returns the air volume and the wind direction to the stored values (step 48), and ends the process of FIG.

As described above, according to the second embodiment, the control processing unit controls to increase the air volume of the air conditioner before changing the set temperature of the air conditioner based on the totalization processing table, and the air direction of the air conditioner. Execute at least one of the controls for directing to the user.
Therefore, the comfort can be improved without changing the set temperature, and thus the power consumption can be further suppressed.

Embodiment 3 FIG.
Only the change in temperature set by a specific user is reflected in the control of the air conditioner 20 only by the operation history from the remote controller by the user. As a result, the comfort of all the users in the area covered by the air conditioner 20 is improved. There is a case where the sex is not maintained. It is also desirable to obtain a large number of operation histories in order to improve the accuracy of the tabulation process.

  Therefore, in this third embodiment, instead of using the remote controller of the air conditioner 20, by using a system that users can operate from their own terminals such as a web operation system, more users' opinions are collected, Reflect in control.

  FIG. 14 is a block diagram showing an air conditioning control system according to Embodiment 3 of the present invention. In FIG. 14, the air conditioning control unit 10 includes an operation receiving unit (Web server) 15, and a plurality of user terminals 30 are arranged in an area covered by the air conditioner 20.

  The operation reception unit 15 constitutes a system that allows the user to operate the air conditioner 20 through the individual user terminal 30. Here, when the operation history data is stored, the operation history storage unit 11 stores information that can identify the user, such as the user's IP address, in association with the operation history.

  In the air conditioning control system shown in FIG. 14, the tally processing unit 13 takes the operation history data and the temperature history data as an input and totals the average time until the set temperature is changed, and creates a tally processing table. When doing so, calculate the discomfort time for each user. However, if an attempt is made to create a tabulation processing table for each user, long-term history data is required to collect a necessary amount of data. There may also be users who do not operate at all.

  Therefore, in the air conditioning control system according to Embodiment 3 of the present invention, users are classified based on attributes that are likely to affect the preference of the air conditioning environment, such as age, sex, height, and weight. For example, as shown in FIG. 15, users are classified by gender and age, and a tabulation process table is created for each attribute.

  The attribute information is set by the user and stored in the user terminal 30 in advance. The attribute information is notified to the air conditioning control unit 10 together with the operation history when the air conditioner 20 is operated.

  In the air conditioning control system shown in FIG. 14, the control processing unit 14 first determines which user is in the room from the online state of the user terminal 30 during the control process. Further, the control processing unit 14 refers to the attribute-specific totaling process table created by the totaling process from the attribute information of the resident person, and calculates the average value of each table as shown in FIG. Take. The control processing unit 14 performs control similar to the control processing of the first embodiment or the second embodiment using the average value table.

  In addition, when there is an average value table in which the set air temperature is different (setting direction “UP” / “DOWN”) at the same intake air temperature, the control processing unit 14 takes a majority decision among the occupants, Use the average value table that is larger. In addition, when the number of persons is completely the same, the control processing unit 14 does not control the intake air temperature, and performs control by deleting the row of the intake air temperature from the average value table. In addition, the control processing unit 14 updates the average value table each time the online state of the user terminal 30 changes due to the entry or exit of a person.

As described above, according to the third embodiment, the operation history storage unit stores the change history of the set temperature for the air conditioner by a plurality of users as the operation history data, and the totalization processing unit stores the plurality of users. Are classified based on predetermined attributes, and a tabulation process table is created for each attribute. The control processing unit identifies users existing in the area covered by the air conditioner, and specifies the attribute information of the identified users. Based on the attribute total processing table, an average value table is created, and the set temperature of the air conditioner is changed using the average value table.
Therefore, comfort can be improved for all users existing in the area covered by the air conditioner.
