BEST MODE FOR CARRYING OUT THE INVENTION
<Structure>
[Configuration of the entire system]

The control device 4 is connected to the management device 6 via the Internet 7 and sends operation data of the air conditioner 3 to the management device 6. The operation data includes the indoor temperature, the control executed by the air conditioner 3, the power consumption of the air conditioner 3, and the like. These operation data are detected at regular time intervals, for example, every minute, and are stored in the control device 4. Then, the control device 4 transmits the accumulated operation data to the management device 6 collectively, for example, every hour.
[0015]
The management device 6 is a device that manages the air conditioner 3 connected to the control device 4, and is located in the remote monitoring center 5 remote from the property 2 where the air conditioner 3 is located. The contents of the management performed by the management device 6 include abnormality monitoring, automatic energy saving control, automatic report creation, and the like. The abnormality monitoring determines whether an abnormality has occurred in the air conditioner 3 based on the operation data of the air conditioner 3 sent from the control device 4 and, if an abnormality has occurred, a manager of the property 2 or the like. This is the management content of notifying to. The energy-saving automatic control is a management content of automatically performing the energy-saving control in a predetermined period so that a certain amount of power consumption is reduced in the predetermined period. Automatic report creation is a management content in which a report summarizing the operation effects of energy saving control and the like is automatically created and periodically sent to the owner or manager of the property 2.
[0016]
Hereinafter, the management device 6 will be described in particular with respect to the energy-saving automatic control characteristic of the present invention.
[Configuration of management device]
The management device 6 automatically creates a schedule for energy saving control of the air conditioner 3 based on the operation data sent from the control device 4 and the weather information 80 sent from the weather company 8, and sends the schedule to the control device 4. Send. The schedule of the energy-saving control aims at reducing the power consumption of the air conditioner 3 without impairing the comfort of the indoor environment to be air-conditioned as much as possible, and is a combination of a plurality of control methods. The management device 6 creates an energy saving control schedule of the day based on the latest weather information 80 and the operation data of the previous day every day, and transmits the schedule to the control device 4. The schedule of the energy saving control is created so as to achieve the target amount of power throughout the year. That is, the management device 6 selects a plurality of control methods corresponding to the weather of the day from the weather information 80 and the like, selects a control method capable of further reducing the power consumption from among them, and sets a combined schedule. By doing so, automatic energy saving control is performed to reduce power consumption as much as possible while maintaining comfort.
[0017]
FIG. 2 is a block diagram illustrating a configuration of the management device 6.
The management device 6 includes an integrated power amount calculation unit 60, a required control rate generation unit 61, a discomfort index calculation unit 62, an executable control list generation unit 63, an execution control determination unit 64, an energy saving control schedule creation unit 65, a limit period setting unit. 66, a weight coefficient setting unit 68, a target power amount calculation unit 69, and a storage unit (not shown).
[0018]
<Integrated power calculation unit>
The integrated power amount calculation unit 60 calculates the integrated power amount of the power consumed by the air conditioner 3 from the start date based on the operation data 40 sent from the control device 4. The integrated power amount calculation unit 60 sends the calculated integrated power amount to the required control rate generation unit 61.
<Request control rate generator>
The required control rate generation unit 61 obtains the required control rate by comparing the integrated power amount with the target power amount M1 stored in the storage unit. Here, the target power amount M1 is a daily power consumption amount of the air conditioner 3 targeted in the energy saving control, and is an integrated value from a reference date. The target power amount M1 is calculated by a later-described weight coefficient setting unit 68 and a target power amount calculation unit 69.
[0019]
The required control rate is a control rate required to achieve the target power amount M1, and the control rate is a value obtained by subtracting the actual operation time from the operation time of the air conditioner 3 by the operation time. Is expressed as a percentage. Therefore, the higher the control rate, the shorter the actual operation time. For example, when the integrated power amount up to a certain day exceeds the target power amount M1, a high control rate is required in the subsequent energy saving control, and the operation time of the air conditioner 3 is limited. The required control rate is divided into three stages: high control rate, medium control rate, and low control rate. The required control rate is 40% for the high control rate, 20% for the medium control rate, and 10% for the low control rate. It is stored in the storage unit as the set value M2 of the rate.
[0020]
The required control rate is specifically determined by the following determination condition expressions (1) and (2).
Fm (N−2) ≧ Ft (N−2) (1)
Ft (N-2)> Fm (N-2) -50kWh (2)
N is the accumulated number of days from the start of operation, and indicates the day on which the energy saving control is performed. Fm (N) is the integrated power amount up to the Nth day, and Ft (N) is the target power amount M1 up to the Nth day. Therefore, Fm (N-2) is the integrated power amount two days before the control day, and Fm (N-2) is the target power amount M1 two days before the control day.
[0021]
As shown in FIG. 3, the required control rate is a high control rate when the equation (1) is satisfied, a medium control rate when the equation (2) is satisfied, and a low control rate when the other equation is satisfied. The request control rate generation unit 61 sends the generated request control rate to the execution control determination unit 64.
<Weight coefficient setting unit>
The weight coefficient setting unit 68 is a part that sets a weight coefficient of the target reduction rate for each month. The weight coefficient setting unit 68 stores, as a set value, the weight coefficient for each month input on the input screen shown in FIG. On this input screen, an input field 680 and an average value display field 681 are displayed. In the input field 680, a weight coefficient for each month from April to March of the following year can be input. The average value display field 681 displays the average value of the input weighting coefficients. The storage unit stores a preset weight coefficient, but this value can be changed later.
[0022]
<Target power calculation unit>
The target power amount calculation unit 69 calculates a monthly target power amount of the air conditioner 3 in consideration of the weight coefficient set by the weight coefficient setting unit 68. Specifically, it is calculated as follows.
First, a target reduction rate is calculated. The target reduction rate is the target reduction rate of the power consumption relative to the power consumption in the base year, and adds 5% as a margin to the reduction rate of the power consumption guaranteed by the remote monitoring center 5 for the property owners and the like. Value.
[0023]
Next, the target amount of power reduction for each month is calculated by the following equation.
ΔPi = Wi × qi × R (%) / 20 (%)
ΔPi is the target power reduction amount for each month, Wi is the power consumption amount for each month in the base year, qi is the weighting factor for each month, and R is the target reduction rate.
Next, the target power consumption per day in each month is calculated by the following equation.
[0024]
pi = (Wi−ΔPi) / Δdi
pi is the target power consumption per day in each month, and Δdi is the number of days in each month.
Then, the integrated value of the target power consumption per day is calculated for 365 days every day from April to March of the following year, and stored in the storage unit as the target power consumption M1.
<Discomfort index calculator>
The discomfort index calculation unit 62 calculates the discomfort index based on the weather information 80 and sends it to the executable control list generation unit 63. The weather information 80 is composed of the outside air temperature and the outside air humidity. The discomfort index is obtained by the following equation (3).
[0025]
D = 0.81 × T + 0.01 × H × (0.99 × T-14.3)
+46.3 (3)
D represents the discomfort index, T represents the outside air temperature, and H represents the outside air humidity.
If the discomfort index is 70, it is determined that some of the persons are uncomfortable, if the index is 75, half of the persons are uncomfortable, and if it is 80, all of the persons are uncomfortable.
[0026]
<Executable control list generator>
The executable control list generation unit 63 generates an executable control list that lists executable control methods among various control methods based on the control method switching condition M3 and the discomfort index stored in the storage unit. Here, as shown in FIG. 4, the control method switching condition M3 includes various control methods, control rates in each control method, and upper and lower limits of the discomfort index that can select each control method and control rate. It shows the relationship. Control methods include capacity control and intermittent control. The capacity control is a control method for performing the operation while limiting the capacity. For example, the control method for the upper limit of the capacity control of 40% is a control method for performing the operation with the upper limit of 40% of the rated capacity. In both the capacity control and the intermittent operation, the upper limit and the lower limit of the selectable discomfort index differ depending on the upper limit of the capacity and the control rate. Whether or not selection is possible is determined depending on whether the indoor environment deteriorates or whether a predetermined power reduction effect cannot be expected, and is set in advance by the developer.
[0027]
The executable control list generation unit 63 enters the control method into the executable control list only when a certain control method can be performed to set a predetermined indoor environment. Specifically, based on the upper and lower limits of the discomfort index set for each control method switching condition and the discomfort index calculated by the discomfort index calculation unit 62, a control method that satisfies the following determination condition formula (4) is implemented. Put in the available control list.
[0028]
A1 ≦ D ≦ A2 (4)
A1 is the lower limit of the selectable discomfort index, D is the discomfort index calculated by the discomfort index calculator 62, and A2 is the upper limit of the selectable discomfort index.
This determination is made for all control methods, and an executable control list as shown in FIG. 5 is generated. In the executable control list, で あ れ ば indicates that each control method can be performed, and X indicates that the control method cannot be performed. The executable control list is sent to the execution control determining unit 64. Note that the executable control list generation unit 63 may generate the executable control list based on an index indicating the state of the outside air other than the discomfort index.
[0029]
<Execution control decision section>
The execution control deciding unit 64 decides a control method from the required control rate and a list of all executable control methods in accordance with the following priority order.
(I) Select a control method equal to the required control rate from the control methods that can be implemented.
(II) If there is no control method with a control rate equal to the required control rate, a control method with the closest control rate is selected from among the control methods that can be implemented.
[0030]
When a plurality of control methods are selected up to (III) and (II), priority is given to capability control.
When a plurality of performance controls are selected up to (IV) and (III), a performance control with a strong suppression effect is selected.
(V) When there is no executable control method in the executable control list, the control is not performed, that is, the energy saving control is not performed.
[0031]
<Limited period setting section>
The limit period setting unit 66 receives an input of a limit period during which no control, that is, energy saving control is not performed. The restriction period setting unit 66 receives an input of a restriction period on a restriction period input screen 660 as shown in FIG. The restriction period input screen 660 includes a restriction period display column 661, a restriction period input column 662, an add button 663, a delete button 664, and the like. The restriction period display field 661 displays the restriction period that has already been input. The limit period can be entered up to the date and time zone. The date and time zone of the restriction period are input in the restriction period input field 662. Further, by pressing the add button 663, another limit period can be added after the limit period is input. Further, by selecting the already input restriction period and pressing the delete button 664, the already input restriction period can be deleted and the once set restriction period can be released. Note that the restriction period may be a period during which the energy saving control is gradual, as well as the case where the energy saving control is not performed at all.
[0032]
<Energy saving control schedule creation section>
The energy saving control schedule creation unit 65 creates a schedule using the control method determined by the execution control determination unit 64, and sends the schedule to the control device 4 of the air conditioner 3. Here, the date and time zone accepted by the restriction period setting unit 66 is deleted from the schedule, that is, the restriction period is excluded from the schedule.
[0033]
FIG. 7 shows an example of the schedule created by the energy-saving control schedule creating unit 65. This schedule is a schedule from 8:00 on May 30 to 8:00 on May 31 the next day. In this schedule, first, during the daytime from 8:00 on May 30 to 18:00 on the same day, a control method of the capacity upper limit of 40% is performed at a control rate of 10%. During the night from 18:00 on May 30 to 8:00 on the 31st of the next morning, the intermittent operation with the control rate of 10% is performed.
[0034]
<Procedure until energy saving control is performed>
FIG. 8 shows a flow showing a procedure when the management device 6 creates a schedule and energy saving control is performed in the air conditioner 3.
First, in step S1, the integrated electric energy is calculated based on the operation data 40. The calculated integrated power amount is sent to the required control rate generation unit 61, and the process proceeds to step S2.
[0035]
In step S2, the required control rate is generated from the integrated power amount and the target power amount M1. The generated required control rate is sent to the execution control determining unit 64.
On the other hand, in step S3, the discomfort index is calculated based on the weather information 80. The calculated discomfort index is sent to the executable control list generation unit 63, and the process proceeds to step S4.
[0036]
In step S4, an executable control list is generated based on the discomfort index and the control method switching condition M3, and is sent to the execution control determining unit 64.
In step S5, the control method to be executed is determined from the required control rate generated in step 2 and the executable control list generated in step S4. The determined control method is sent to the energy saving control schedule creation unit 65, and the process proceeds to step S7.
[0037]
On the other hand, in step S6, a limit period is input and accepted. The input limit period is sent to the energy saving control schedule creation unit 65.
In step S7, an energy-saving control schedule is created from the control method determined in step S5. Then, the restriction period input in step S6 is deleted from the created schedule. The created schedule is sent to the control device 4 via the Internet 7 (see FIG. 1).
[0038]
In step S8, the control device 4 having received the schedule controls the air conditioner 3 according to the schedule control method, and energy saving control is performed.
The above procedure is performed every day of the year. In the management device 6, a schedule is created every day throughout the year so as to achieve the target reduction rate in one year, but the schedule creation interval and the period for achieving the target reduction rate are limited to these. Not something. For example, a schedule may be created at intervals shorter than one day, such as day and night, or at intervals longer than one day, such as once every few days. Further, a schedule may be created so as to achieve the target reduction rate in a period shorter than one year, such as six months, or in a period longer than one year, such as several years.
[0039]
Note that the target power amount M1 is obtained in advance according to the following procedure flow.
(Procedure for calculating target electric energy)
FIG. 10 shows a procedure flow for calculating the target power amount M1.
First, a target reduction rate is calculated in step S21. The target reduction rate is calculated by adding 5% to the guaranteed reduction rate of power consumption guaranteed by the remote monitoring center 5 for the property owner and the like. Then, the process proceeds to step S22.
[0040]
In step S22, a monthly weighting factor for the target reduction rate is set, and the process proceeds to step S23. Note that the order of step S21 and step S22 may be reversed.
In step S23, the target amount of power reduction for each month is calculated. The target reduction power amount for each month is calculated from the power consumption amount for each month in the base year, the weight coefficient for each month, and the target reduction rate. Then, the process proceeds to step S24.
[0041]
In step S24, the target electric energy per day in each month is calculated. The target power amount is calculated from the power consumption amount in each month of the base year, the target reduction power amount in each month, and the number of days in each month. Then, the process proceeds to step S25.
In step S25, the integrated value of the target power consumption per day is calculated for each day of the year and stored in the storage unit as the target power consumption M1.
[0042]
<Features>
In the management device 6 of the equipment management system 1, the target reduction power amount for each month is calculated in consideration of the weight for each month. For this reason, it is possible to assign a target reduction power amount by weighting each month from April to March so that the target reduction rate for the whole year can be achieved. Therefore, the management device 6 can reduce the possibility that the target reduction rate cannot be achieved by inputting the monthly weight so that the target reduction rate over the whole year is easily achieved.
[0043]
For example, as shown in FIG. 9, the weighting factor from April to July may be 0.4 and the weighting factor from August to March may be 0.1. In this way, the amount of power consumption can be significantly reduced between April and July, so even if it becomes difficult to achieve the monthly target power reduction from August onward, one year will be required. There is little risk that the total target power reduction will not be achieved.
[0044]
In order to reduce the possibility that the target amount of power reduction over the whole year will not be achieved, it is conceivable to increase the margin for calculating the target reduction rate. However, in this case, since the suppression of the operation of the air conditioner 3 by the energy-saving control is uniformly increased for one year, it is difficult to maintain a comfortable environment. However, since a weighting factor is set for each month in the management device 6, it is easy to adjust the operation of the air conditioner 3 every month. Therefore, it is possible to reduce the possibility that the target reduction rate cannot be achieved while maintaining a comfortable environment as a whole.
[0045]
The weighting factor setting unit 68 may set a monthly weighting factor based on a weather forecast that predicts long-term weather conditions. For example, in the weather forecast, the weight coefficient is reduced in a month in which a severe weather condition such as a hot summer or a severe winter is expected to increase the power consumption of the air conditioner 3. Then, the weight coefficients for the other months may be increased. In this way, the possibility that the target reduction rate for the whole year cannot be achieved can be reduced more reliably.
