Description

  The present invention relates to a control device, a control method, and a program.

  In recent years, a technique for reducing energy consumption in facilities such as buildings has attracted attention. As such a technique, many have been proposed to control loads such as air conditioners and lighting fixtures installed in a facility so that peak power consumed in the facility does not exceed a reference value (for example, patent documents). 1 and 2). The peak power generally means the maximum value of the amount of power used for 30 minutes.

  In the technique described in Patent Document 1, when the current power is larger than the target current power, the power of the air conditioner is suppressed in a predetermined priority order. In the technique described in Patent Document 2, the air conditioning monitoring panel selects an indoor unit having a small air conditioning load from a plurality of indoor units in response to a demand from the outside, and reduces the air conditioning capability of the selected indoor unit. . Thereby, the influence on the specific person by the fall of an air-conditioning capability can be suppressed.

  However, in the technique described in Patent Document 1, since an air conditioner in which power is preferentially suppressed is determined in advance, the user's comfort may be greatly impaired depending on the position of the air conditioner and the air environment.

  Moreover, in the technique described in Patent Document 2, the air conditioning capacity is simply reduced in order from the indoor unit with the smallest air conditioning load. Here, when there are a plurality of indoor units having different air conditioning loads in one air-conditioned space, it is considered that the air conditioning load of other indoor units changes due to a decrease in the air conditioning capability of some indoor units. Since it takes time to measure such a change in air conditioning load, it also takes time to select an appropriate indoor unit, and as a result, the user's comfort may be impaired.

  The present invention has been made under the above circumstances, and an object thereof is to improve user comfort.

To achieve the above object, a control device of the present invention, a data acquisition means for acquiring data indicating the air temperature definitive to each of the plurality of conditioned spaces, from a change of the air temperature in each of the plurality of conditioned spaces, a plurality of For each of the air- conditioned spaces, calculation means for calculating an index value indicating the ease of air temperature change and each of the plurality of air-conditioning devices are controlled according to the index value of the air-conditioned space to be air-conditioned by the air-conditioning device Control means, and the index value is T1, the current air temperature is T1, the air temperature when the air-conditioning apparatus for air-conditioning is activated is T2, and the time elapsed since the air-conditioning apparatus was activated Is the air temperature change rate D expressed by the following equation, where A is the length of the air conditioner and N is the number of air conditioners .

  According to the present invention, the air conditioner is controlled according to the index value calculated for each of the air conditioned spaces. Thereby, a user's comfort can be improved.

As illustrated in FIG. 3, the control device 100 includes a floor diagram holding unit 110 that holds a floor diagram, a user interface 120 that receives information from an administrator and presents information to the administrator, and external devices.

  The data acquisition unit 140 is realized mainly by the cooperation of the processor 11, the input unit 14, and the communication unit 16. The data acquisition unit 140 acquires the floor plan data 111 from the floor plan holding unit 110. In addition, the data acquisition unit 140 acquires information directly input to the control device 100 by the administrator from the user interface 120, and from the communication interface 130, the measurement result of the power by the measurement device 200 and the suction by the air conditioners 301 to 314. The temperature measurement result and the information transmitted from the terminal 410 are acquired.

  The control unit 150 is mainly realized by the processor 11. The control unit 150 includes a condition setting module 151 that sets control conditions for controlling the air conditioners 301 to 314, a space recognition module 152 that recognizes the air conditioned spaces of the air conditioners 301 to 314, and air conditioning in each air conditioned space.

  The condition setting module 151 sets control conditions based on data input by the administrator. The control condition according to the present embodiment is that the value of power supplied in a certain time via power line L1 exceeds a threshold value (upper limit value). This certain time is, for example, 30 minutes. The condition setting module 151 stores, for example, the threshold value input to the control device 100 or the terminal 410 by the administrator in the data management unit 160 as the control condition data 161 indicating the control condition.

  The space recognition module 152 recognizes the air-conditioned space to be air-conditioned for each of the air-conditioning devices 301 to 314 based on the floor diagram data 111 acquired from the floor diagram holding unit 110 by the data acquisition unit 140. The air-conditioned space means an area where the conditioned air blown out from the air outlets of the air-conditioning equipment 301 to 314 reaches.

  The calculation module 153 calculates an index value for each air-conditioned space based on the data stored in the data management unit 160. The index value which concerns on this Embodiment shows the ease (degree of difficulty) of the temperature change of air when the air conditioners 301-314 harmonize air.

  The control determination module 154 determines whether the control condition set by the condition setting module 151 is satisfied and notifies the output control module 155 of the determination result. The output control module 155 controls the air conditioners 301 to 314 according to the index value calculated by the calculation module 153 when the control determination module 154 determines that the control condition is satisfied.

  The data management unit 160 includes control condition data 161 indicating control conditions set by the condition setting module 151, temperature transition data 162 indicating the measurement results of the suction temperature by the air conditioners 301 to 314 in time series, and the space recognition module 152. And air-conditioning data 163 indicating information related to the air-conditioned space recognized by. These data may be XML format data or CSV (Comma-Separated Values) format data.

  The temperature transition data 162 is data that associates the value of the suction temperature measured by the air conditioners 301 to 314 with the time at which this value was measured. The temperature transition data 162 is accumulated in the data management unit 160 by the data acquisition unit 140. The temperature transition data 162 may be data that associates the measured value of the suction temperature with the time when the value is acquired by the data acquisition unit 140. In addition, the time associated with the value of the suction temperature may be defined by the length of time that has elapsed since the activation of the air conditioners 301 to 314, or the length of time that has elapsed since the start of the control device 100. May be defined by

  The air conditioning data 163 is data that associates information about the air-conditioned space recognized by the space recognition module 152 with the index value calculated by the calculation module 153.

  Next, a series of processes executed by the control device 100 will be described using the flowchart shown in FIG. The process shown in FIG. 4 starts when the control device 100 is turned on. The process shown in FIG. 4 is mainly executed by the processor 11, but will be described below using the configuration shown in FIG. 3 as appropriate.

  As shown in FIG. 4, the control unit 150 executes an initialization process (step S1), and then repeatedly executes an output control process (step S2). These initialization processing and output control processing will be described in order.

  FIG. 5 shows details of the initialization process. As shown in FIG. 5, in the initialization process, first, the data acquisition unit 140 acquires the contents of the control condition from the user interface 120 (step S11). Specifically, the data acquisition unit 140 causes the user interface 120 to display a screen that prompts the administrator to input the upper limit value of power supplied via the power line L1. The data acquisition unit 140 acquires a value input to the user interface 120 by the administrator.

  Next, the condition setting module 151 stores the value acquired in step S11 in the data management unit 160 as the control condition data 161 (step S12).

  Next, the data acquisition unit 140 acquires the floor plan data 111 from the floor plan holding unit 110 (step S13). Thereafter, the space recognition module 152 recognizes the air-conditioned space (step S14).

  Specifically, the space recognition module 152 reads the floor plan data 111 acquired in step S13 and determines whether the rooms to which the two air conditioners belong are equal. That is, the space recognition module 152 determines whether or not a room defined by a wall surrounding one air conditioner is equal to a room defined by a wall surrounding another air conditioner.

  When this determination is affirmed, the space recognition module 152 recognizes that the two air-conditioning equipments target the same air-conditioned space as the air-conditioning target. On the other hand, if the determination is negative, the space recognition module 152 recognizes that the two air-conditioning devices are air-conditioning targets in different air-conditioning spaces. Then, the space recognition module 152 repeats the above determination for all the combinations of two air conditioning devices. The space recognition module 152 assigns an appropriate number to the recognized air-conditioned space.

  FIG. 6 shows the recognition result of the air-conditioned space by the space recognition module 152. In FIG. 6, the air conditioners 301 to 303 use the air-conditioned space 501 as the air-conditioning target, the air-conditioning equipment 304 to 306 uses the air-conditioned space 502 as the air-conditioning target, and the air-conditioning equipment 307 to 314 uses the air-conditioned space 503 as the air-conditioning target. In the example shown in FIG. 6, each of the air-conditioned spaces 501 to 503 is substantially equal to the rooms A1 to A3.

  Next, the space recognition module 152 stores the recognition result of the air-conditioned space as the air-conditioning data 163 in the data management unit 160 (step S15). The air conditioning data 163 according to the present embodiment has a first table 163a shown in FIG. 7 and a second table 163b shown in FIG.

  The first table 163a is data in a table format that associates a column 51 indicating the number of the air-conditioned space, a column 52 indicating the number of air-conditioning devices, and a column 53 indicating the index value. The number of the air-conditioned space is assumed to be the same as that of the air-conditioned spaces 501 to 503 shown in FIG. The number of air-conditioning devices means the number of air-conditioning devices that are air-conditioned in each of the air-conditioned spaces 501 to 503. The space recognition module 152 creates columns 51 and 52 in the first table 163a. Note that the column 53 is created by the calculation module 153.

  The second table 163b is data in a table format that associates the number of the air conditioner and the number of the air-conditioned space in which the air conditioner is installed.

  Returning to FIG. 5, after step S15, the process by the control unit 150 returns from the initialization process to a series of processes shown in FIG. The controller 150 executes an output control process following the initialization process. This output control process will be described in detail with reference to FIG.

  First, the data acquisition unit 140 acquires the suction temperature of the air that each of the air conditioners 301 to 314 has sucked from the conditioned space from each of the air conditioners 301 to 314 via the communication interface 130 (step S21).

  Next, the data acquisition unit 140 adds time information to the suction temperature acquired in step S21 and adds it to the temperature transition data 162 (step S22). By repeating this process, the temperature transition data 162 indicates the transition of the suction temperature in each of the air-conditioned spaces.

  Next, the control unit 150 determines whether or not the accumulated amount of the temperature transition data 162 is greater than or equal to a certain level (step S23). Specifically, the control unit 150 determines whether or not the temperature transition data 162 is accumulated in an amount necessary for calculating the index value. For example, the control unit 150 determines whether or not the transition of the suction temperature measured for 5 minutes or more after the air conditioners 301 to 314 start operation is stored in the data management unit 160 as the temperature transition data 162. To do.

  When it is determined that the accumulated amount of the temperature transition data 162 is not equal to or greater than a certain level (step S23; No), the process of the control unit 150 returns from the output control process to a series of processes shown in FIG. On the other hand, when it is determined that the accumulated amount of the temperature transition data 162 is greater than or equal to a certain amount (step S23; Yes), the calculation module 153 calculates the rate of change of the temperature of air in each of the air-conditioned spaces 501 to 503 (step S24). ). For example, the calculation module 153 calculates the change rate based on the following equation (1).

  However, D in the above formula (1) means a change rate. Σ means the total sum of air-conditioning equipment that targets the same air-conditioned space, T1 means the current suction temperature measured by the air-conditioning equipment, and T2 is measured first when the air-conditioning equipment starts up Means the suction temperature. A means the time elapsed since the activation of the air-conditioning equipment, and N means the number of air-conditioning equipment whose air-conditioning space is to be air-conditioned.

  For example, the change rate D for the air-conditioned space 501 is the sum of the absolute values of the differences between the current suction temperatures of the air-conditioning equipment 301 to 303 for the air-conditioned space 501 and the suction temperature at the start-up. It is obtained by dividing the time (minutes) that has elapsed since the start of 301 to 303 by 3. The calculation module 153 performs similar calculations for the other air-conditioned spaces 502 and 503.

  Next, the calculation module 153 sets the index value of the air-conditioned space with the smallest change rate to 100 (maximum value) (step S25). Specifically, the calculation module 153 determines that the air-conditioned space with the smallest change rate is an air-conditioned space that hardly changes in temperature, and sets the index value of the air-conditioned space to 100, which is the maximum value.

  Next, the control determination module 154 acquires a measured value of supply power and control condition data 161 (step S26). Specifically, the control determination module 154 reads the temperature transition data 162 from the data management unit 160. However, the control determination module 154 may directly acquire the power measurement result by the measurement device 200 via the communication interface 130 and the data acquisition unit 140. In addition, the control determination module 154 reads the control condition data 161 from the data management unit 160.

  Next, the control determination module 154 determines whether or not the control condition is satisfied (step S27). Specifically, the control determination module 154 compares the measured power value acquired in step S <b> 26 with the upper limit value indicated by the control condition data 161. And the control determination module 154 determines whether the electric power supplied to a some apparatus should be restrict | limited from the ratio of the measured value and upper limit at the present time.

  For example, when the upper limit value indicated by the control condition data 161 is 10 kWh and the measured value of power supplied in 15 minutes up to the current time is 6 kWh, 6 kWh of power is supplied in the next 15 minutes. Since the power supplied in 30 minutes exceeds the upper limit value, it is determined that the supply power should be limited.

  When it is determined that the control condition is not satisfied (step S27; No), the process by the control unit 150 returns from the output control process to a series of processes shown in FIG. On the other hand, when it is determined that the control condition is satisfied (step S27; Yes), the calculation module 153 sets the index value of the air-conditioned space with the maximum change rate calculated in step S24 to zero (minimum value). (Step S28). Specifically, the calculation module 153 determines that the air-conditioned space having the maximum rate of change is an air-conditioned space that easily changes in temperature, and sets the index value of the air-conditioned space to zero, which is the minimum value.

  In addition, the calculation module 153 sets the index value of the air-conditioned space whose change rate is not minimum or maximum so that the change rate corresponds to the index value. For example, when the change rates of the suction temperatures in the air-conditioned spaces 501 to 503 are 1.1 ° C./min, 0.6 ° C./min, and 0.1 ° C./min, respectively, the index values of the air-conditioned spaces 501 to 503 Are calculated as zero (minimum value), 50, and 100 (maximum value), respectively. Then, as shown in FIG. 7, the calculation module 153 stores the calculated index value in the data management unit 160 as the column 53 of the first table 163a.

  Next, the output control module 155 controls the outputs of the air conditioners 301 to 314 according to the index value calculated by the calculation module 153 (step S29). Specifically, the output control module 155 preferentially suppresses the output of the air conditioner that targets the air-conditioned space with a small index value over the output of the air conditioner that targets the air-conditioned space with a large index value.

  FIG. 10 shows the output levels of the air conditioners 301 to 306 when the index value of the air-conditioned space 501 is 60 and the index value of the air-conditioned space 502 is 40. In addition, this output level is a level prescribed | regulated by making the maximum value of the cooling capacity or heating capacity of an air-conditioning apparatus into 100. FIG. In the example shown in FIG. 10, the index value is equal to the output level, but the present invention is not limited to this. For example, the output control module 155 may suppress only the output of the air conditioning equipment that targets the air conditioned space with the smallest index value.

  As described above, in the present embodiment, control device 100 calculates an index value for each of air-conditioned spaces 501 to 503 and controls air conditioners 301 to 314 according to the index values. Thereby, the control apparatus 100 can adjust the output of the air-conditioning equipment 301-314 according to the characteristic of each air-conditioned space.

  For example, when the power supplied to the air conditioners 301 to 314 is restricted, if the outputs of the air conditioners 301 to 314 are equally suppressed, the time required for air conditioning after the restriction on the power is released varies depending on the air conditioned space. it is conceivable that. On the other hand, control device 100 according to the present embodiment equalizes the time required for the air temperature in the plurality of air-conditioned spaces to reach the set temperature after limiting the power supplied to air-conditioning equipment 301-314. Can be made. Therefore, the control apparatus 100 can reduce energy consumption, without reducing only the comfort of the user who exists in a specific air-conditioning space. In other words, it is possible to improve user comfort when suppressing energy consumption.

  Further, the index value according to the present embodiment is calculated based on the transition of the actually measured air temperature. For this reason, the control apparatus 100 can control the air-conditioning equipment 301-314 according to the actual characteristic of air-conditioned space. The index value was defined based on the rate of change calculated by the calculation shown in the above equation (1). Therefore, the index value is calculated with a relatively simple arithmetic expression, and the load on the processor 11 can be reduced.

  For convenience, the index value has been described as being simply defined based on the rate of change in air temperature. However, it is preferable to unify the conditions for the rate of change for defining the index value in a plurality of conditioned spaces. For example, the change rate of the air temperature when the set temperature is 27 ° C. at the output level 50 and the change rate of the air temperature when the set temperature is 24 ° C. at the output level 100 are considered to be different. For this reason, it is preferable to define the index value based on the rate of change of the air temperature when at least one of the output level and the set temperature is equal in the plurality of conditioned spaces.

Embodiment 2. FIG.
Next, Embodiment 2 of the present invention will be described with reference to the drawings. In addition, about the structure same or equivalent to Embodiment 1, while using an equivalent code | symbol, the description is abbreviate | omitted or simplified.

  The control device 100 according to the present embodiment differs from that according to the first embodiment in that whether or not the control condition is satisfied is determined based on the current time. Further, control device 100 according to the present embodiment differs from that according to Embodiment 1 in that the index value is calculated based on the time taken for air conditioning.

  The condition setting module 151 according to the present embodiment defines control conditions for controlling the air conditioners 301 to 314 based on the transition of the power value measured by the measuring device 200. For example, when the power measured by the measuring apparatus 200 on the previous day exceeds a preset threshold value in the time from 11:00 to 13:00, the condition setting module 151 indicates that “11:00 to 13:00 The time zone “until 0 minutes” is defined as the time for which the control device 100 controls the air conditioners 301 to 314. Then, the condition setting module 151 stores data describing the time for controlling the air conditioners 301 to 314 in the data management unit 160 as control condition data 161.

  FIG. 11 shows output control processing according to the present embodiment. In this output control process, when it is determined that the accumulated amount of the temperature transition data 162 is greater than or equal to a certain amount (step S23; Yes), the calculation module 153 has applied past air conditioning based on the temperature transition data 162. Time is calculated (step S31). This past air conditioning means what was performed when the air conditioners 301 to 314 were not controlled by the control device 100.

  For example, the calculation module 153 determines the time taken from the start of the operation of the air conditioners 301 to 303 to the time when all the suction temperatures measured in the air conditioned space 501 reach a preset temperature. Calculated as time spent. The calculation module 153 performs similar calculations for the other air-conditioned spaces 502 and 503.

  Next, the calculation module 153 sets the index value of the conditioned space having the longest time for air conditioning to 100 (maximum value) (step S32). Specifically, the calculation module 153 determines that the air-conditioned space with the longest time required for air conditioning is an air-conditioned space that hardly changes in temperature, and sets the index value of this air-conditioned space to 100, which is the maximum value. To do.

  Next, the control determination module 154 acquires the current time and control condition data 161 (step S33). Then, the control determination module 154 determines whether or not the control condition is satisfied (step S34). Specifically, the control determination module 154 determines whether or not the current time is included in the time zone indicated by the control condition data 161.

  When it is determined that the control condition is not satisfied (step S34; No), the process of the control unit 150 returns from the output control process to a series of processes shown in FIG. On the other hand, when it is determined that the control condition is satisfied (step S34; Yes), the calculation module 153 sets the index value of the air-conditioned space with the shortest time calculated in step S31 to zero (minimum value) ( Step S35).

  In addition, the calculation module 153 sets the index value of the air-conditioned space where the time required for air conditioning is not the shortest or longest so that the time corresponds to the index value. For example, when the time taken for air conditioning in the air-conditioned spaces 501 to 503 is 1 minute, 6 minutes, and 11 minutes, respectively, the index values of the air-conditioned spaces 501 to 503 are set to zero (minimum value), 50, Calculated as 100 (maximum value). Then, as shown in FIG. 7, the calculation module 153 stores the calculated index value in the data management unit 160 as the column 53 of the first table 163a.

  As described above, in this embodiment, whether or not the control condition is satisfied is determined based on the current time. Thereby, the time when the air conditioners 301 to 314 are controlled becomes clear in advance, and this time can be notified to the user in advance.

  The index value according to the present embodiment is calculated based on the time taken for air conditioning. For this reason, it is possible to accurately equalize the time required for the air temperature in the plurality of air-conditioned spaces to reach the set temperature.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by the said embodiment.

  For example, the method by which the space recognition module 152 recognizes the air-conditioned space is not limited to that described in the first embodiment. Specifically, the space recognition module 152 is an air-conditioned space to be air-conditioned by a plurality of air-conditioning devices when the distances between one air-conditioning device and the other air-conditioning devices are all equal to or less than a threshold. May be determined to be the same.

  FIG. 12 shows an example of a result of recognizing the air-conditioned space based on the distance between the air-conditioning devices. In FIG. 12, the distance D1 between the air conditioner 308 and the air conditioner 311 is less than the threshold value. A distance D2 between the air conditioner 309 and the air conditioner 311 is equal to or greater than a threshold value.

  In FIG. 12, the air conditioning devices 301 to 303 target the air conditioning space 501, the air conditioning devices 304 to 306 target the air conditioning space 502, and the air conditioning devices 307, 308, 311, and 312 target the air conditioning space 503. The air-conditioning equipment 309, 310, 313, 314 has the air-conditioned space 504 as the air-conditioning target.

  The space recognition module 152 may recognize the air-conditioned space using information input to the user interface 120 by the administrator without using the floor plan data 111.

  The index value according to the first embodiment is calculated based on the rate of change of the air temperature, and the index value according to the second embodiment is calculated based on the time required for air conditioning. The method of calculating is not limited to these. For example, the data acquisition unit 140 acquires the size of the air-conditioned space (for example, the floor area) from the user interface 120, and the calculation module 153 determines the size of the air-conditioned space for the air-conditioning equipment whose air-conditioning target is the air-conditioned space. The index value may be calculated based on the value divided by the number. The number of air conditioners corresponding to the air conditioned space is shown in the first data 163a as shown in FIG.

  Moreover, in the said embodiment, although the output level of the air-conditioning apparatus installed in one air-conditioning space was suppressed equally, it is not limited to this. For example, the time average of the output levels of the air conditioners installed in one air-conditioned space may be equally suppressed. FIG. 13 shows an example of the output levels of the air conditioners 301 to 306 when the index value of the air-conditioned space 501 is 67 and the index value of the air-conditioned space 502 is 40.

By storing and distributing in a recording medium and installing the program P1 in a computer, an apparatus for executing the above-described processing can be configured.
