Description

  The present invention relates to an air conditioning control technique, and more particularly, to an air conditioning control support technique for utilizing a complaint from a resident regarding a cold feeling in air conditioning control.

  In an air conditioning system of a large facility such as a building, feedback control is basically used as air conditioning control (see, for example, Patent Document 1). In other words, if there is a difference in the current indoor temperature measurement value with respect to the indoor temperature target value set by the resident or manager, the air conditioner control variables such as the valve opening are set so that the controller for air conditioning will cancel the difference. change. Therefore, in the conventional air conditioning control, the temperature control of the target space is performed by feedback control based on the temperature fluctuation in the target space.

By the way, managers often receive complaints about thermal sensations from residents. These claims include, for example, a hot feeling claim that the room is hot when the outdoor temperature is particularly high in the summer, and a cold feeling claim that the feet are cold in the winter.
The reason for receiving such a claim is that, for example, the room temperature used for air conditioning control is a value measured at a specific position in the air conditioning zone. It is possible that the overall air conditioning environment is not optimal.

Alternatively, because there is a delay in the target air-conditioning zone (time to cool down to a predetermined temperature / warm up time), a time delay is inevitably generated in the feedback control against the temperature change in the air-conditioning zone when there is a sudden change in the outside air condition. It may be possible to do so.
For example, a place that is susceptible to outside air temperature or solar radiation, such as near the window, may have a higher temperature than the thermometer position, and it may take a long time for the temperature to reach the target value. is there.

  Therefore, in the above-described conventional technology, the temperature control of the target space is performed by feedback control based on the temperature fluctuation in the target space. Therefore, there is a delay in the temperature control, and it is easy to receive a complaint about thermal sensation from the resident. There was a problem.

After correcting from the initial set temperature by a preset correction range, the set temperature in each time zone of the air conditioning control period is output to the air conditioning control device as support information for suppressing the occurrence of complaints in the air conditioning zone. And a preset temperature output unit.

  Also, in one configuration example of the air-conditioning control support device according to the present invention, when the set temperature output unit corrects the set temperature by the correction range, the claim occurrence in the time zone calculated from the claim history data is performed. The correction width is adjusted according to the frequency.

[Principle of the present invention]
Analyzing complaints history data related to complaints about thermal sensation reported in the past by residents, hot complaints during cooling operation often occur when the outside air temperature is somewhat high and the set temperature of the air conditioning zone is relatively high, It has been found that many cold complaints at the time of heating operation occur when the outside air temperature is low to some extent and the set temperature of the air conditioning zone is relatively low. For example, in a certain air-conditioning zone, when the set temperature is 27 ° C. during cooling operation, if the outside air temperature becomes 30 ° C. or more, a sensation of hot feeling that a resident is too hot is generated, and if the outside air temperature is less than 30 ° C. There is a temperature correlation that claims do not occur.

  Such temperature correlation is a characteristic that can be seen both during cooling operation and during heating operation, but if the operation history data including the set temperature and the outside air temperature at the time of the complaint is linked and analyzed, these settings are There is a certain temperature correlation (combination) between the temperature and the outside air temperature, and in the two-dimensional plane between the set temperature and the outside air temperature, the temperature correlation between the set temperature at which the claim is generated and the outside air temperature is constant. It became clear that it was located within the range. Moreover, it turned out that the claim temperature range in which this temperature correlation is located differs for every air-conditioning zone.

  On the other hand, the predicted temperature of the day for the area where the air conditioning zone is located can be easily obtained as weather data via the Internet from a specific provider or weather forecasting agency. This predicted temperature is actually measured during air conditioning control. It was found that there was no significant temperature difference from the outside temperature. Therefore, for a certain air-conditioning zone, when the preset temperature in the air-conditioning control period from 6 o'clock to 20 o'clock every day is specified in advance before the start of air-conditioning control, the expected temperature of the day for the area obtained is It can be used as the outside air temperature.

  The present invention pays attention to the temperature correlation (combination) between the set temperature and the outside air temperature when such a claim occurs and the expected temperature of the weather data can be used as the outside temperature during the air conditioning control period. is there. Then, when the set temperature in each time zone of the air conditioning control period for a certain air conditioning zone is specified in advance before the start of air conditioning control, the obtained predicted temperature is regarded as the outside air temperature, and the initial set temperature and the temperature correlation between the air conditioning zone Based on the above, it is highly probable that a claim will occur in a time zone in which the temperature correlation between the initial setting temperature and the predicted temperature is included in the claim temperature range indicating the range in which the claim has occurred in the past. It is specified as the claim prediction period.

The air conditioning control support device 10 executes the claim occurrence prediction process of FIG. 5 in response to an instruction from the administrator before the start of the air conditioning control. Note that at the start of execution of the claim occurrence prediction process, the history data DB 21 stores claim history data indicating claims that have occurred in the past and operation history data at the time of claim occurrence, and the weather data DB 22 stores the air conditioning control period. It is assumed that meteorological data is accumulated.

First, the claim analysis unit 11 obtains claim history data related to the air-conditioning zone Z from the history data DB 21 (step 100), and the operation history data indicating the set temperature and the outside air temperature of the air-conditioning zone Z at the time of the occurrence of the claim as history data. Obtained from the DB 21 (step 101).
Next, the claim analysis unit 11 analyzes the temperature correlation (combination) between the set temperature at which the claim is generated in the air-conditioning zone Z and the outside air temperature from the claim history data and the operation history data. A claim temperature range indicating the included temperature range is derived (step 102).

  FIG. 6 is a graph showing an example of a temperature correlation between the set temperature and the outside air temperature related to a hot feeling complaint. Here, among the two-dimensional planes in which the hot feeling claims that have occurred in the past in the air-conditioning zone Z have the outside temperature as the horizontal axis and the set temperature as the vertical axis, the set temperature and the outside air temperature at the time when the hot feeling claim occurs It is plotted at the position specified by. In this example, when the set temperature is 27 ° C. in the air-conditioning zone Z, it is indicated that a hot feeling complaint has occurred in the temperature range where the outside air temperature is 30 ° C. or higher. Therefore, the temperature range in which the set temperature is 27 ° C. or higher and the outside air temperature is 30 ° C. or higher is the claim temperature range related to the hot feeling claim in the air conditioning zone Z.

  FIG. 7 is a graph showing an example of the temperature correlation between the set temperature and the outside air temperature related to the cold feeling complaint. Here, the cold feeling claims that occurred in the past in the air-conditioning zone Z are the two-dimensional planes with the outside air temperature as the horizontal axis and the set temperature as the vertical axis. It is plotted at the position specified by. In this example, when the set temperature is 22 ° C. in the air-conditioning zone Z, it is indicated that a hot feeling complaint has occurred in the temperature range where the outside air temperature is 7 ° C. or less. Therefore, the temperature range in which the set temperature is 22 ° C. or less and the outside air temperature is 7 ° C. or less is the claim temperature range related to the cold feeling claim in the air conditioning zone Z.

  Next, the claim prediction unit 12 acquires the predicted temperature of the area where the air conditioning zone Z is located from the weather data DB 22 (step 103), and the air conditioning control designated by the administrator who manages the air conditioning control of the air conditioning zone Z. An initial set temperature assigned in advance as a set temperature in each time zone of the period is acquired (step 104).

Moreover, the claim prediction part 12 calculates the claim occurrence frequency in each time slot | zone from the claim history data regarding the air-conditioning zone Z acquired from history data DB21 (step 105).
FIG. 8 is a calculation example showing the complaint occurrence frequency. Here, the number of complaints that occurred in the past year is counted as the complaint frequency for each time zone from 6:00 to 20:00. In this example, it can be seen that no complaints have occurred in the past one year at 6-7 o'clock, 12 o'clock, 18-20 o'clock.

  Subsequently, the claim predicting unit 12 determines that the temperature correlation between the initial set temperature and the expected temperature is within the claim temperature range in each time zone of the air conditioning control period based on the predicted temperature, the initial set temperature, and the claim occurrence frequency. And the time zone in which the complaint occurrence frequency is equal to or higher than the reference frequency is specified as the complaint prediction period (step 106).

  Thereafter, the occurrence prediction notification unit 13 claims the claim prediction period in the air conditioning control period specified by the claim prediction unit 12 in the air conditioning zone Z to the manager terminal 30 of the manager who manages the air conditioning control of the air conditioning zone Z. Is notified as support information indicating a period during which the occurrence of a complaint is likely to occur (step 107), and a series of claims occurrence prediction processing is terminated.

  FIG. 9 is an explanatory diagram illustrating a specific example of the claim prediction period. Here, an example is shown in which a claim prediction period is specified based on a hot feeling claim during cooling operation. In FIG. 9, the predicted temperature Te is a graph showing a change in the predicted temperature related to the area where the air-conditioning zone Z acquired from the weather data DB 22 is located.

  As shown in FIG. 6, when the temperature range where the set temperature is 27 ° C. or higher and the outside air temperature is 30 ° C. or higher is the claim temperature range related to the hot feeling claim in the air conditioning zone Z, the predicted temperature Te is 30 ° C. or higher. A period from before 11:00 to past 15:00 becomes the complaint occurrence area Rc. Therefore, when the claim occurrence frequency is not considered, the period tc of the claim occurrence area Rc is specified as the claim prediction period.

  On the other hand, when considering the claim occurrence frequency, if the reference frequency is once, the period from the time 12:00 to the time 13:00 in the claim occurrence area Rc where the claim occurrence frequency is 0 and does not satisfy the reference frequency Becomes the exclusion period tn, and the period te in which the exclusion period tn is excluded from tc is specified as the claim prediction period.

[Effect of the first embodiment]
As described above, the present embodiment includes the temperature correlation (combination) between the set temperature at which the complaint occurs in the air-conditioning zone Z and the outside air temperature from the complaint history data and the operation history data. A claim temperature range indicating a temperature range is derived, and the claim prediction unit 12 performs initial setting in each time zone of the air conditioning control period based on the designated initial set temperature and the predicted temperature in the area where the air conditioning zone Z is located. A time zone in which the temperature correlation between the temperature and the predicted temperature is included in the claim temperature range is specified as a claim prediction period, and is output as support information for supporting air conditioning control.

  Thereby, in the air conditioning zone Z, a period during which a complaint is likely to occur in the air conditioning control period can be specified as the complaint prediction period. For this reason, the administrator who manages the air-conditioning control of the air-conditioning zone Z sets the period during which a complaint is likely to occur in the air-conditioning zone Z based on the claim prediction period notified as support information from the air-conditioning control support device 10. Can be figured out before it begins.

  Therefore, the administrator can perform prior work such as fine adjustment of the set temperature of the air conditioning zone Z set in the air conditioning control device 41 and other air conditioning control parameters for the claim prediction period. For this reason, even when there is a control delay due to a deviation in the measurement position of the room temperature or a control delay that the feedback control potentially has, it is possible to suppress the occurrence of complaints due to these control delays.

[Second Embodiment]
Next, with reference to FIG. 10, the air-conditioning control assistance apparatus 10 concerning the 2nd Embodiment of this invention is demonstrated. FIG. 10 is a block diagram illustrating a configuration of an air-conditioning control support apparatus according to the second embodiment.
In 1st Embodiment, the case where the period which a complaint tends to generate | occur | produce among air-conditioning control periods was specified as a claim prediction period was demonstrated as an example. In the present embodiment, a case where the set temperature corrected based on the claim prediction period is output as the set temperature at each time used in the air conditioning control device 41 will be described as an example.

  In the present embodiment, the air conditioning control support device 10 is provided with a set temperature output unit 14. The occurrence prediction notification unit 13 is not directly related to the set temperature output unit 14 and may be omitted.

  The set temperature output unit 14 presets the set temperature in each time zone of the claim prediction period specified by the claim prediction unit 12 from the initial set temperature in a direction in which the temperature correlation of the time zone shifts outside the claim temperature range. A function of correcting only the corrected correction range, a function of outputting the set temperature in each time zone of the air conditioning control period to the air conditioning control device 41 as support information for suppressing the occurrence of complaints in the air conditioning zone Z, and correcting the set temperature When correcting only the width, it has a function of adjusting the size of the correction width according to the claim occurrence frequency in the time zone calculated from the claim history data.

[Operation of Second Embodiment]
Next, the set temperature correction process according to the present embodiment will be described with reference to FIG. FIG. 11 is a flowchart showing the set temperature correction process.
The air conditioning control support device 10 executes the set temperature correction process of FIG. 10 according to an instruction from the administrator before the start of the air conditioning control.

  At the start of execution of the set temperature correction process, the history data DB 21 stores complaint history data indicating complaints that have occurred in the past and operation history data at the time of the occurrence of the complaint, and the weather data DB 22 stores the air conditioning control period. It is assumed that meteorological data is accumulated. Further, steps 100 to 105 in FIG. 11 are the same as those in FIG. 10 described above.

First, the claim analysis unit 11 obtains claim history data related to the air-conditioning zone Z from the history data DB 21 (step 100), and the operation history data indicating the set temperature and the outside air temperature of the air-conditioning zone Z at the time of the occurrence of the claim as history data. Obtained from the DB 21 (step 101).
Next, the claim analysis unit 11 analyzes the temperature correlation (combination) between the set temperature at which the claim is generated in the air-conditioning zone Z and the outside air temperature from the claim history data and the operation history data. A claim temperature range indicating the included temperature range is derived (step 102).

Next, the claim prediction unit 12 acquires the predicted temperature of the area where the air conditioning zone Z is located from the weather data DB 22 (step 103), and the air conditioning control designated by the administrator who manages the air conditioning control of the air conditioning zone Z. An initial set temperature assigned in advance as a set temperature in each time zone of the period is acquired (step 104).
Moreover, the claim prediction part 12 calculates the claim occurrence frequency in each time slot | zone from the claim history data regarding the air-conditioning zone Z acquired from history data DB21 (step 105).

  Subsequently, the claim predicting unit 12 determines that the temperature correlation between the initial set temperature and the expected temperature is within the claim temperature range in each time zone of the air conditioning control period based on the predicted temperature, the initial set temperature, and the claim occurrence frequency. And the time zone in which the complaint occurrence frequency is equal to or higher than the reference frequency is specified as the complaint prediction period (step 106).

  Next, the set temperature output unit 14 sets the set temperature in each time zone of the claim prediction period specified by the claim prediction unit 12 so that the temperature correlation in the time zone shifts outside the claim temperature range. The correction width is corrected by a preset correction width (step 200). At this time, the size of the correction width is adjusted according to the complaint occurrence frequency in the time zone calculated from the complaint history data.

  Thereafter, the set temperature output unit 14 outputs the set temperature in each time zone of the air conditioning control period to the air conditioning control device 41 as support information for suppressing the occurrence of complaints in the air conditioning zone Z (step 201). The set temperature correction process ends.

  FIG. 12 is a graph showing a set temperature correction example related to a hot feeling claim. Here, in the claim temperature range shown in FIG. 6, the initial set temperature 27 ° C. is lowered by the correction width 1 ° C. to 26 ° C. in the direction in which the temperature correlation of each time zone shifts outside the claim temperature range. It has been corrected. Note that the outside temperature other than the claim temperature range remains at the initial set temperature of 27 ° C.

  FIG. 13 is a graph showing a set temperature correction example related to a cold feeling complaint. Here, in the claim temperature range shown in FIG. 7, the initial set temperature 22 ° C. is increased by a correction width of 1 ° C. in the direction in which the temperature correlation of each time zone shifts outside the claim temperature range to 23 ° C. It has been corrected. Note that the outside temperature other than the claim temperature range remains at the initial set temperature of 22 ° C.

  FIG. 14 is an explanatory diagram illustrating a specific example of the claim prediction period. Here, an example is shown in which a claim prediction period is specified based on a hot feeling claim during cooling operation. In FIG. 14, the predicted temperature Te is a graph showing a change in the predicted temperature related to the area where the air-conditioning zone Z acquired from the weather data DB 22 is located.

  As shown in FIG. 12, when the temperature range where the set temperature is 27 ° C. or more and the outside air temperature is 30 ° C. or more is the claim temperature range related to the hot feeling claim in the air conditioning zone Z, the expected temperature Te is 30 ° C. or more. A period from before 11:00 to past 15:00 becomes the complaint occurrence area Rc. Therefore, when the claim occurrence frequency is not considered, the period tc of the claim occurrence area Rc is specified as the claim prediction period. For this reason, the set temperature in each time zone of tc is corrected to 26 ° C., which is lowered by the temperature width of 1 ° C. from the initial set temperature of 27 ° C., and the corrected set temperature Tr in each time zone of these air conditioning control periods is the air conditioning control device. 41 is output.

  On the other hand, when considering the claim occurrence frequency, if the reference frequency is once, the period from the time 12:00 to the time 13:00 in the claim occurrence area Rc where the claim occurrence frequency is 0 and does not satisfy the reference frequency Becomes the exclusion period tn, and the period te in which the exclusion period tn is excluded from tc is specified as the claim prediction period. For this reason, the set temperature in each time zone of tc is corrected to 26 ° C., which is lowered from the initial set temperature of 27 ° C. by the temperature width of 1 ° C. Of these, tn remains at the initial set temperature of 27 ° C. The corrected set temperature Tr in each time zone of the period is output to the air conditioning control device 41.

  In addition, as shown in FIG. 8, for the 13:00 time point, the frequency of complaint occurrence is very high at 25 times, so the correction width of 1 ° C. is adjusted by the adjustment amount of 0.5 ° C., and the correction width of 1.5 ° C. It is good also as ° C. As a result, the set temperature at the time of 13:00 is 25.5 ° C. Accordingly, it is possible to increase the effect of suppressing the occurrence of complaints in the time zone in which the complaint occurrence frequency is high and the possibility of occurrence of complaints is high. The relationship between the complaint occurrence frequency and the adjustment range may be set in advance.

[Effect of the second embodiment]
Thus, in the present embodiment, the set temperature output unit 14 sets the initial set temperature in the direction in which the temperature correlation in each time zone of the claim prediction period shifts outside the claim temperature range. After correcting by a preset correction range, the set temperature in each time zone of the air conditioning control period is output to the air conditioning control device as support information for suppressing the occurrence of complaints in the air conditioning zone Z. .

  Thereby, the preset temperature in the claim prediction period is automatically corrected to the initial preset temperature and output to the air conditioning control device. Therefore, the administrator can omit the preliminary work of finely adjusting the set temperature of the air-conditioning zone Z set in the air-conditioning control device 41 for the claim prediction period, and the occurrence of claims can be avoided without increasing the work burden of the administrator. It becomes possible to suppress.

  In the present embodiment, when the set temperature output unit 14 corrects the set temperature by the correction width, the correction temperature is adjusted according to the claim occurrence frequency in the time zone calculated from the claim history data. You may do it.
