(Embodiment)
(Constitution)
FIG. 1 shows the functional configuration of the power management apparatus. The power management device 1 includes an acquisition unit 11, a storage unit 12,
Temperature range determination unit 13, room temperature prediction unit 14, operation plan creation unit 15, display unit 16, determination unit 17,
The notification unit 18 is provided.

The acquisition unit 11 uses the comfortable temperature setting information, which is information for defining the comfortable temperature range, the room temperature prediction information, which is information related to changes in the room temperature on the target day, or electricity for air conditioners, etc., which is applied in advance by the tenant administrator. Get the operating time of the equipment. The comfortable temperature range is the room temperature at which most people in the tenant feel comfortable. The comfortable temperature range is preset. The information necessary for the setting is the comfortable temperature setting information. The comfortable temperature setting information includes, for example, the work content to be performed outside the predetermined time set by the building manager, or the work amount obtained by digitizing the work content.

FIG. 2 shows an example of a table in which the work content 12a, the work amount 12b, and the comfortable temperature range 12c are associated with each other. When the work content 12a is desk work or the work amount 12b is 1, the comfortable temperature range 12c is set from 22 degrees to 24 degrees. When the work content 12a includes work such as transportation of a lightweight object such as a file, or the work amount 12b is 3, the comfortable temperature range 12c is 20 degrees to 2 degrees.
It is set twice. When the work content 12a includes work such as changing the layout of the office and carrying heavy objects such as unloading, or when the work amount 12b is 5, the comfortable temperature range 12c is from 18 degrees to 2 degrees.
It is set at 0 degrees. The contents and numerical values of the table shown in FIG. 2 are examples.

That is, the suitable comfortable temperature range 12c is set from the work content 12a or the work amount 12b input by the tenant administrator. However, the method of determining the comfortable temperature range does not have to be determined from the work content or the work amount, and may be determined from other information, or the comfortable temperature range may be directly determined.

Room temperature prediction information is, for example, information such as temperature, humidity, weather, wind strength, and sunshine amount in the weather forecast, number of windows in the tenant area, size, orientation, and size of buildings around the tenant. Information such as the size and time of day when the tenant area is hidden behind the surrounding buildings.

The storage unit 12 stores the suitable comfortable temperature range in the tenant acquired by the acquisition unit 11, the room temperature prediction information, and the operating time of an electric device such as an air conditioner applied in advance by the tenant administrator. Further, a table associating information for determining a comfortable temperature range with the comfortable temperature range as shown in FIG. 2, a change in room temperature predicted by the room temperature predicting unit 14, and an operation plan created by the operation plan creating unit 15 are stored. ..

The temperature range determination unit 13 determines the comfortable temperature range from the comfortable temperature setting information acquired by the acquisition unit 11 and the table which stores the comfortable temperature setting information and the comfortable temperature range stored in the storage unit 12 as shown in FIG. decide.

The room temperature prediction unit 14 predicts a change in the room temperature of the tenant area from the comfortable temperature range and the room temperature prediction information. The predicted change in room temperature is stored in the storage unit 12.

The operation plan creation unit 15 creates an operation plan of electric equipment such as an air conditioner from the change in the room temperature predicted by the room temperature prediction unit 14. The created operation plan is stored in the storage unit 12.

The display unit 16 displays the operation plan of the electric device created by the operation plan creation unit 15. The medium for displaying is a monitor or screen. If the power management apparatus 1 does not have a screen, it is displayed on the connected monitor.

The determination unit 17 stores the operating time of an electric device such as an air conditioner, which is stored in the storage unit 12 and which is applied in advance by the tenant administrator, and the electric device or the like on the target day, which is created by the operation plan creating unit 15. From the operation plan, it is determined whether or not the applied operation time is significantly different from the created operation plan.

When the determination unit 17 determines that the difference is large, the notification unit 18 notifies the tenant administrator of that.

(Action)
FIG. 3 shows a flowchart regarding the operation of the power management apparatus 1. First, the acquisition unit 11 of the power management apparatus 1 acquires comfort temperature setting information, which is information for defining a comfort temperature range (S1).
1). The comfortable temperature setting information is, for example, work content or work amount.

After that, the temperature range determination unit 13 sets an appropriate comfort temperature range from the table of correspondence between the work content or work amount acquired by the acquisition unit 11 and the work content or work amount stored in the storage unit 12 and the comfortable temperature range. Yes (S12).

For example, the table of FIG. 2 is stored in the storage unit 12. By registering the work content or work volume to be performed when operating electrical equipment such as air conditioners outside the preset time from the tenant administrator,
The acquisition unit 11 acquires the work content or the work amount. For example, when the acquisition unit 11 acquires desk work as the work content, the temperature range determination unit 13 sets the comfortable temperature range to 22 from the table of FIG.
Set from 24 to 24 degrees.

Then, the room temperature predicting unit 14 predicts the change in the room temperature from the appropriate comfortable temperature range that is set and the room temperature predicting information that is information related to the change in the room temperature of the target day acquired by the acquiring unit 11 (
S13).

Next, the operation plan creation unit 15 creates an operation plan for maintaining the comfortable temperature range (S
14). Then, the display unit 16 displays the created operation plan (S15).

Then, the determination unit 17 stores the operation time of an electric device such as an air conditioner stored in the storage unit 12 in advance from the tenant administrator, and the electric device on the target day created by the operation plan creation unit 15. It is determined whether or not the air conditioning operation time zone of the created operation plan is shorter than the requested time based on the operation plans such as (S16).

When the estimated driving time of the driving plan is shorter than the requested driving time (Yes in S16)
), and the notification unit 18 notifies the tenant administrator to that effect (S17). The notification method is performed, for example, by sending an e-mail to the tenant administrator or through a screen such as a system for applying for overtime driving. The notification gives the tenant administrator an opportunity to change the applied driving time.

On the other hand, when the estimated driving time of the operation plan is equal to or longer than the applied driving time (N in S16)
o), the notification unit 18 does not notify the tenant administrator.

The flowchart of FIG. 3 is performed each time the room temperature prediction information acquired by the acquisition unit 11 is updated. This is because the room temperature prediction information includes, for example, a weather forecast, and the weather forecast is generally more accurate the closer to the target day.

In addition, depending on the operation method of the building, the application for operating the air conditioner or the like outside of the preset time may be accepted from several months before. However, the weather forecast for a few months ahead does not provide the daily information, or even if it does, the accuracy is not good. The calculation of the driving time based on the weather forecast is performed from the day when the daily weather forecast is available to the day before the target day.

FIG. 4 to FIG. 8 show an example of an operation plan of an air conditioner as an example of an operation plan of an electric device after a predetermined time, which is created by the power management apparatus 1 according to this embodiment.

(An example of an air conditioner operation plan after a specified time in winter)
FIG. 4 shows that the operating time of the air conditioner operating in the heating mode is set to 4 times from the preset time in winter.
It is an example of an operation plan when extending time. However, the default time set by the building administrator is 9
It is set from 18:00 to 18:00 (first time zone).

In FIG. 4, the time outside the predetermined time is 4 hours (second time zone) from 18:00 to 22:00. This time is referred to as an extended work time zone 41. Further, the comfortable temperature range 42 is determined from the comfortable temperature setting information applied by the tenant administrator. The method for determining the comfortable temperature range is the same method as S12 in the flowchart of FIG.

When the target day for extension is, for example, 7 days or more, the weather forecast included in the room temperature prediction information acquired by the acquisition unit 11 is not fixed, and the expected temperature on the target day has a certain range. Therefore, the room temperature predicting unit 14 predicts changes in the room temperature when the predicted temperature is high and when the predicted temperature is low.

When the predicted temperature is high, the room temperature change prediction 43 when the predicted temperature is high deviates from the comfortable temperature range 42, based on the room temperature change prediction 44 when the air conditioner is not operated, it is determined to be around 20:00. In this case, the tenant area is kept in the comfortable temperature range 42 even if the operation of the air conditioner is started from about 20:00 instead of 18:00 which is the start time of the extension application. Therefore, the operation plan creation unit 15 creates the room temperature change prediction 45 and the operation plan when the air conditioner is operated at 20:00.

If you apply for overtime operating hours according to the operation plan, the overtime air conditioning operating time zone 50 will be 20
It is 22:00 from the time, which is 2 hours shorter than the operation time without referring to the operation plan.

On the other hand, when the expected temperature is low, the room temperature change prediction 46 when the expected temperature is low deviates from the comfortable temperature range 42 based on the room temperature change prediction 47 when the air conditioner is not operated is determined to be around 18:30. It In this case, the tenant area is kept in the comfortable temperature range 42 even when the operation of the air conditioner is started from around 18:30, not at 18:00 which is the start time of the extension application. Therefore, the operation plan creation unit 15 creates the room temperature change prediction 48 when operating the air conditioner at 18:30.

If you apply for the overtime operation time as per the operation plan, the overtime air conditioning operation time zone 49 will be 18
It is from 2:30 to 22:00, which is 30 minutes shorter than the operation time without referring to the operation plan.

(An example of an air conditioner operation plan after a preset time on a relatively warm winter day)
FIG. 5 is an example of an operation plan when the operating time of the air conditioner operating in the heating mode is extended by 4 hours from the preset time on a relatively warm day in winter. However, the default time set by the building manager is 9:00 to 18:00 (first time zone). It is assumed that the expected temperature on the target day of the operation plan of FIG. 5 is higher than the target temperature of the target operation plan of FIG.

In FIG. 5, the time outside the predetermined time is 4 hours (second time zone) from 18:00 to 22:00. This time is referred to as an extended work time zone 51. In addition, the comfortable temperature range 52 is determined from the comfortable temperature setting information applied by the tenant administrator. The method of determining the comfortable temperature range 52 is the same as the method of determining the comfortable temperature range S12 in the flowchart of FIG.

It is determined that the room temperature change prediction 53 when the expected temperature on the target day is high deviates from the comfortable temperature range 52 not within the extended work time zone 51. In this case, the tenant area is kept in the comfortable temperature range 52 without applying for extension of the air conditioner. Therefore, the operation plan creation unit 15 creates an operation plan when the air conditioner is not operated in the extended work time zone 51.

When the operation time of the extended work time zone 51 is applied according to the operation plan, the air conditioning is not operated outside the time, so the operation time is shortened by 4 hours compared to the operation time not referring to the operation plan.

On the other hand, the room temperature change prediction 56 when the predicted temperature is low deviates from the comfortable temperature range 52.
From the room temperature change prediction 57 when the air conditioner is not operated, it is determined to be around 19:20. In this case, the tenant area is kept in the comfortable temperature range 52 even when the operation of the air conditioner is started from around 19:20, not at 18:00 which is the start time of the application for extending the operation of the air conditioner. Therefore, the operation plan creation unit 15 creates the room temperature change prediction 58 when the air conditioner is operated at 19:20.

If you apply for the overtime operation time as per the operation plan, the overtime air conditioning operation time zone 59 will be 19
The time is from 20 minutes to 22:00, which is 1 hour and 20 minutes shorter than the operation time without referring to the operation plan.
(An example of an air conditioner operation plan after the preset time when setting the upper limit of the comfortable temperature range at the end of the preset time in winter)

FIG. 6 shows that the operating time of the air conditioner operating in the heating mode is 4 hours from the preset time in winter.
It is an example of an operation plan when extending time. However, the default time set by the building administrator is 9
It is set from 18:00 to 18:00 (first time zone).

In FIG. 6, the time outside the predetermined time is 4 hours (second time zone) from 18:00 to 22:00. This time is referred to as an extended work time zone 61. Further, the comfortable temperature range 62 is determined from the comfortable temperature setting information applied by the tenant administrator. The method of determining the comfortable temperature range is the same method as S12 in the flowchart of FIG.

In addition, the room temperature is set near the upper limit value of the comfortable temperature range 62 at 18:00, which is the end time of the predetermined time. This is to avoid operating the air conditioner as much as possible outside the preset time.

The room temperature change prediction 63 when the expected temperature is high deviates from the comfortable temperature range 62 based on the room temperature change prediction 64 when the air conditioner is not operated, at around 21:30. In this case, the tenant area is kept in the comfortable temperature range 62 even if the operation of the air conditioner is started from around 21:30, not at 18:00 which is the start time of the extension application. Therefore, the operation plan creation unit 15 creates the room temperature change prediction 65 and the operation plan when the air conditioner is operated at 21:30.

If you apply for overtime operating hours according to the operation plan, the overtime air conditioning operating time zone 70 will be 21
It is from half-hour to 22:00, which is shortened by 3 hours and half compared to the operation time without referring to the operation plan.

On the other hand, the room temperature change prediction 66 when the predicted temperature is low deviates from the comfortable temperature range 62 because
From the room temperature change prediction 67 when the air conditioner is not operated, it is determined to be around 19:40. In this case, the tenant area is kept in the comfortable temperature range 62 even if the operation of the air conditioner is started from around 19:40, not at 18:00, which is the start time of the extension application. Therefore, the operation plan creation unit 1
5 creates a room temperature change prediction 68 when the air conditioner is operated at 19:40.

If you apply for overtime operating hours according to the operation plan, the overtime air conditioning operating time zone 69 will be 19
From 40 minutes to 22:00, it will be shortened by 1 hour and 40 minutes from the operation time without referring to the operation plan.

(An example of an air conditioner operation plan before a specified time in winter)
FIG. 7 shows that the operating time of the air conditioner operating in the heating mode is 4 hours from the preset time in winter.
It is an example of an operation plan in the case of extending before time. However, the default time set by the building manager is 8:00 to 17:00 (first time zone).

In FIG. 7, the time outside the predetermined time is 4 hours (second time zone) from 4:00 to 8:00. This time is referred to as an early exit work time zone 71. In addition, the comfortable temperature range 72 is determined from the comfortable temperature setting information applied by the tenant administrator. The method for determining the comfortable temperature range is the same method as S12 in the flowchart of FIG.

The room temperature change prediction 73 when the expected temperature on the target day is high deviates from the comfortable temperature range 72 from the room temperature change prediction 74 when the air conditioner is not operated at about 5:20. In this case, the tenant area is kept in the comfortable temperature range 72 even if the operation of the air conditioner is started from around 5:20 instead of 4:00 which is the start time of the extension application. Therefore, the operation plan creation unit 15 creates the room temperature change prediction 75 and the operation plan when the air conditioner is operated at 5:20.

Further, it is considered that the operation of the air conditioner is stopped midway during the early-advance work time period 71 within a range not departing from the comfortable temperature range 72. By gradually delaying the time when the operation of the air conditioner is stopped from the time when the operation is started, the time when the operation of the air conditioner is stopped midway within the range that does not deviate from the comfortable temperature range 72 is obtained. In FIG. 7, the tenant area is kept in the comfortable temperature range 72 even if the air conditioner is not continuously operated until 8 o'clock but is stopped around 6:30.

Therefore, the operation plan creation unit 15 corrects the room temperature change prediction 75 and the operation plan when the air conditioner is operated at 5:20 and stopped at 6:30. When the overtime operation time is applied according to the operation plan, the overtime air conditioning operation time zone 79 is from 5:20 to 6:30, which is shortened by 2 hours and 50 minutes from the operation time not referring to the operation plan.

On the other hand, when the expected temperature is low, the room temperature change prediction 76 is already at the comfortable temperature range 7 at 4 o'clock.
Deviates from 2. Therefore, the time to start the operation of the air conditioner is 4:00. Further, considering that the operation of the air conditioner is stopped halfway during the early-working time period 71 within a range that does not deviate from the comfortable temperature range 72, in FIG. 7, instead of continuing to operate the air conditioner until 8 o'clock, Even if it is stopped around 6:30, the tenant area is kept in the comfortable temperature range 72.

Therefore, the operation plan creation unit 15 creates the room temperature change prediction 78 when the air conditioner is operated at 4:00 and the air conditioner is stopped at 6:30. When the overtime operation time is applied according to the operation plan, the overtime air-conditioning operation time zone 80 is from 4:00 to 6:30, which is shortened by one and a half hours from the operation time not referring to the operation plan.

(An example of an air conditioner operation plan after a specified time in summer)
FIG. 8 shows that the operation time of the air conditioner operating in the cooling mode is 4 hours from the preset time in the summer.
It is an example of an operation plan when extending time. However, the default time set by the building administrator is 9
It is set from 18:00 to 18:00 (first time zone).

In FIG. 8, the time outside the predetermined time is 4 hours (second time zone) from 18:00 to 22:00. This time is referred to as an extended work time zone 81. Further, the comfortable temperature range 82 is determined from the comfortable temperature setting information applied by the tenant administrator. The method for determining the comfortable temperature range is the same method as S12 in the flowchart of FIG.

The room temperature change prediction 83 when the expected temperature is high deviates from the comfortable temperature range 82 from the room temperature change prediction 84 when the air conditioner is not operated, and is determined to be around 18:30. In this case, the tenant area is kept in the comfortable temperature range 82 even if the operation of the air conditioner is started from around 18:30, not at 18:00 which is the start time of the extension application. Therefore, the operation plan creation unit 15 creates the room temperature change prediction 85 and the operation plan when the air conditioner is operated at 18:30.

If you apply for overtime operating hours according to the operation plan, the overtime air conditioning operating time zone 89 will be 18
It is from 2:30 to 22:00, which is 30 minutes shorter than the operation time without referring to the operation plan.

On the other hand, the room temperature change prediction 86 when the expected temperature is low deviates from the comfortable temperature range 82.
From the room temperature change prediction 87 when the air conditioner is not operated, it is determined to be around 20:00. in this case,
Even if you start the operation of the air conditioner around 20:00 instead of 18:00 which is the start time of the extension application,
The tenant area is kept in the comfortable temperature range 82. Therefore, the operation plan creation unit 15 creates the room temperature change prediction 88 when the air conditioner is operated at 20:00.

If you apply for the overtime operation time as per the operation plan, the overtime air conditioning operation time zone 90 will be 20
It is 22:00 from the time, which is 2 hours shorter than the operation time without referring to the operation plan.

Considering the comfortable temperature setting information, which is the information to determine the comfortable temperature range, or the room temperature prediction information, which is the information related to the change in the room temperature on the target day, the tenant is provided with the information on the start and stop times of the suitable electric equipment. By providing it, tenant managers may apply for operating hours of electrical equipment outside the hours so that operating hours of electrical equipment such as air conditioners can be shortened within the range where people in the tenant area do not feel uncomfortable. it can.

Further, by shortening the operating time of an electric device such as an air conditioner, it is possible to contribute to the reduction of the environmental load due to the use of electricity or the reduction of the heat island phenomenon due to the exhaust heat from the outdoor unit. Also, the building manager can socially appeal that the building is environmentally friendly.

The comfortable temperature range, which is the room temperature at which the person in the tenant feels comfortable, can be determined not only from the work content or work amount as in this embodiment, but also from other information. In that case, the storage unit stores the correspondence between the information and the comfortable temperature range. Also, the comfortable temperature range can be directly set.

Further, in the present embodiment, the operation plan creation unit creates a plan regarding the operating time of the electric device such as the air conditioner, but the tenant administrator pays not only the operating time outside the default time but also the operating intensity and the like. In case of fluctuations, it is possible to create an operation plan regarding the operation time and strength of the electric equipment.

Further, in the present embodiment, the use of the electric device outside the predetermined hours is mainly described as the use of the air conditioner, but it is subject to the billing of the electric charge outside the hours specified by the building manager.
