FIG. 2 is a diagram illustrating an example of an air conditioning system of the air conditioning energy management system according to the first embodiment.
In the example shown in FIG. 2, eight indoor units 11 are installed in the target space 10. Among these indoor units 11, a first outdoor unit 12A is connected to four adjacent indoor units 11a, 11b, 11c, and 11d. A second outdoor unit 12B is connected to the remaining four indoor units 11.

  The outdoor units 12A and 12B share the target space 10 with the outdoor unit air conditioning areas A and B for air conditioning, and the indoor units 11a to 11d share the indoor unit air conditioning areas a to d for air conditioning. That is, the indoor unit 11a air-conditions the indoor unit air-conditioning area a, the indoor unit 11b air-conditions the indoor unit air-conditioning area b, the indoor unit 11c air-conditions the indoor unit air-conditioning area c, and the indoor unit 11d is the indoor unit air-conditioning area d.

Next, operation | movement of the arithmetic processing part 26 of the energy management apparatus 2 is demonstrated.
FIG. 4 is a flowchart illustrating an example of a processing procedure performed by the air conditioning energy management system according to the first embodiment. This process is a process performed by the arithmetic processing unit 26 at regular intervals. The process described below is a process that is periodically performed by the calculation processing unit 26 at least once every minute in order to calculate the control set value of the air conditioning system 1.

The arithmetic processing unit 26 reads out the stay / absence information or the number of people information for each movement detection area from the measurement data storage unit 23. Based on the read result, the arithmetic processing unit 26 determines stay / absence or counts the number of people for each indoor unit air-conditioning area (step S401).
As a first specific example of step S401, determination of stay / absence for each indoor unit air-conditioning area based on stay / absence information for each movement detection area will be described.
FIG. 5 is a diagram illustrating an example of a stay / absence determination result for each indoor unit air-conditioning area based on the stay / absence information for each movement detection area by the air-conditioning energy management system according to the first embodiment.
First, the relationship between the movement detection areas of the movement detection units 14a to 14f will be described.
In the example shown in FIG. 5, for the movement detection area of the movement detection unit 14 a, the movement detection area of the movement detection unit 14 b and the movement detection area of the movement detection unit 14 c are adjacent to each other, and the movement detection unit 14 d For the detection area, the movement detection area of the movement detection unit 14e and the movement detection area of the movement detection unit 14f are adjacent to each other in a row.
Further, the movement detection area of the movement detection unit 14a is adjacent to the movement detection area of the movement detection unit 14d, the movement detection area of the movement detection unit 14b is adjacent to the movement detection area of the movement detection unit 14e, and the movement detection unit 14c The detection area is adjacent to the movement detection area of the movement detection unit 14f.
As described above, the movement detection areas of the movement detection units 14a to 14f are further divided into four areas to form a square area.

Next, correspondence between the movement detection areas of the movement detection units 14a to 14f and the indoor unit air conditioning areas a to d will be described.
A total of six areas including the four movement detection areas of the movement detection section 14a and two areas adjacent to the movement detection area of the movement detection section 14a among the movement detection areas of the movement detection section 14b are the indoor unit air conditioning area a. Corresponding to
The total of six areas including the four movement detection areas of the movement detection section 14c and the two areas adjacent to the movement detection area of the movement detection section 14c among the movement detection areas of the movement detection section 14b are indoor unit air conditioning. Corresponds to area b.
Also, a total of six areas including the four movement detection areas of the movement detection section 14d and two areas adjacent to the movement detection area of the movement detection section 14d among the movement detection areas of the movement detection section 14e are indoor unit air conditioning. Corresponds to area c.
Also, a total of six areas including four movement detection areas of the movement detection section 14f and two areas adjacent to the movement detection area of the movement detection section 14f among the movement detection areas of the movement detection section 14e are the indoor unit air conditioning. Corresponds to area d.
Information indicating these correspondences is stored in the system model storage unit 24.

  When determining the stay / absence of each indoor unit air-conditioning area, the arithmetic processing unit 26 selects one indoor unit air-conditioning area to be stayed / absent from the indoor unit air-conditioning area, and selects the selected indoor unit air-conditioning area. If there is at least one area where it is determined that a person stays among a plurality of movement detection areas corresponding to, it is determined that a person stays in the indoor unit air conditioning area to be determined. On the other hand, if there is no area where it is determined that a person stays in the plurality of movement detection areas corresponding to the selected indoor unit air conditioning area, the arithmetic processing unit 26 indicates that there is no person in the indoor unit air conditioning area to be determined. Judge that there is. The arithmetic processing unit 26 repeats this determination for each indoor unit air conditioning area.

In the example illustrated in FIG. 5A, the arithmetic processing unit 26 acquires, from the air conditioning system 1, a determination result that a person stays in four areas among the six dynamic detection areas corresponding to the indoor unit air conditioning area a. . Based on the determination result, the arithmetic processing unit 26 determines that a person stays in the indoor unit air conditioning area a as shown in FIG.
In addition, the arithmetic processing unit 26 acquires from the air conditioning system 1 the determination result that no person is present in any of the six dynamic detection areas corresponding to the indoor unit air conditioning area b. Based on this determination result, the arithmetic processing unit 26 determines that no person is present in the indoor unit air-conditioning area b as shown in FIG.
In addition, the arithmetic processing unit 26 acquires a determination result from the air conditioning system 1 that a person stays in two of the six dynamic detection areas corresponding to the indoor unit air conditioning area c. The arithmetic processing unit 26 determines that a person stays in the indoor unit air-conditioning area c as shown in FIG.
In addition, the arithmetic processing unit 26 acquires from the air conditioning system 1 a determination result that a person stays in one of the six dynamic detection areas corresponding to the indoor unit air conditioning area d. Based on the determination result, the arithmetic processing unit 26 determines that a person stays in the indoor unit air conditioning area d as shown in FIG.

  Thus, even if the classification of the indoor unit air conditioning area in the target space and the classification of the dynamic detection area for each dynamic detection unit 14 do not match, the indoor unit air conditioning based on the dynamic detection result by the dynamic detection unit 14 You can determine the movement of people in the area. That is, the stay / absence information and the number of people information determined by the movement detection unit 14 can be converted into the stay / absence information and the number of people information for each indoor unit air conditioning area. As a result, it is not always necessary to provide the movement detection unit 14 for stay / absence detection or number detection for each indoor unit air conditioning area. That is, it is not necessary to match the classification of the indoor unit air-conditioning area in the target space with the classification of the dynamic detection area of the dynamic detection unit 14.

Next, as a second specific example of step S401, determination of the number of persons for each indoor unit air-conditioning area based on the number of persons detected for each movement detection area by the movement detection unit 14 will be described.
FIG. 6 is a diagram illustrating an example of a calculation result of the number of persons for each indoor unit air-conditioning area based on the number of persons information for each movement detection area by the air-conditioning energy management system according to the first embodiment.
As illustrated in FIG. 6, the arithmetic processing unit 26 sets the sum of the number of people in each motion detection area corresponding to the indoor unit air conditioning area as the number of indoor unit air conditioning areas.

  In the example shown in FIG. 6A, the arithmetic processing unit 26 has people staying in four of the six dynamic detection areas corresponding to the indoor unit air conditioning area a, and the number of people in these areas is two. The determination result that one person, one person, and two persons are obtained from the air conditioning system 1. The arithmetic processing unit 26 adds up the number of persons indicated by the determination result, and determines that the number of persons in the indoor unit air-conditioning area a is six as shown in FIG.

  In the example illustrated in FIG. 6A, the arithmetic processing unit 26 acquires a determination result from the air conditioning system 1 that the number of persons in any of the six dynamic detection areas corresponding to the indoor unit air conditioning area b is zero. The arithmetic processing unit 26 determines that the number of people in the indoor unit air-conditioning area b is 0 as shown in FIG.

  In the example shown in FIG. 6A, the arithmetic processing unit 26 has people staying in two of the six dynamic detection areas corresponding to the indoor unit air-conditioning area c, and the number of people in these areas is two. The determination result that one person is present is acquired from the air conditioning system 1. The arithmetic processing unit 26 adds up the number of persons indicated by the determination result, and determines that the number of persons in the indoor unit air-conditioning area c is three as shown in FIG.

  In the example shown in FIG. 6A, the arithmetic processing unit 26 has a person staying in one of the six dynamic detection areas corresponding to the indoor unit air conditioning area d, and the number of people in this area is two. The determination result that there is is acquired from the air conditioning system 1. Based on the determination result, the arithmetic processing unit 26 determines that the number of persons in the indoor unit air conditioning area d is two as shown in FIG.

  For the control of the indoor unit 11, the arithmetic processing unit 26 operates / stops the indoor unit 11, the set temperature, the air volume, the wind direction, etc. based on the determination result of stay / absence of the indoor unit air conditioning area or the determination result of the number of people. Is calculated for each indoor unit air conditioning area, and the calculation result is stored in the calculation result storage unit 27.

The control set value output unit 28 outputs the calculation result stored in the calculation result storage unit 27 to the air conditioner control device 13 of the air conditioning system 1 as a control set value.
The air conditioner control device 13 controls the indoor unit 11 in the air conditioning system 1 using the control set value output from the energy management device 2 (step S402). The arithmetic processing unit 26 repeats steps S401 and S402 for each indoor unit air conditioning area.

For example, when the determination result that a person stays in a certain indoor unit air-conditioning area is acquired from the air-conditioning system 1, the arithmetic processing unit 26 calculates the calculation result that the indoor unit 11 corresponding to this indoor unit air-conditioning area is operated. The result is stored in the result storage unit 27.
Moreover, the arithmetic processing part 26 calculates the calculation result that the indoor unit 11 corresponding to this indoor unit air conditioning area is stopped, when the determination result that there is no person in a certain indoor unit air conditioning area is acquired from the air conditioning system 1. The result is stored in the result storage unit 27.

Moreover, when the determination result which shows the number of persons in a certain indoor unit air-conditioning area is acquired from the air conditioning system 1, the arithmetic processing part 26 is set by the indoor unit 11 corresponding to a corresponding indoor unit air-conditioning area based on this number of persons. The temperature is calculated, and the calculation result is stored in the calculation result storage unit 27.
FIG. 7 is a diagram illustrating an example of a relationship between the number of indoor unit air-conditioning areas of the air-conditioning energy management system according to the first embodiment and the set temperature by the indoor unit corresponding to this area.
In the example shown in FIG. 7, at the time of cooling, when the number of persons in a certain indoor unit air-conditioning area is two or more, the arithmetic processing unit 26 sets a preset temperature of the indoor unit 11 corresponding to this area. The calculation result indicating that the temperature is obtained is stored in the calculation result storage unit 27. The reference temperature information is stored in the system model storage unit 24 and can be changed by an input from the model parameter input unit 25.
Further, when the number of people in this indoor unit air conditioning area decreases to less than two, the arithmetic processing unit 26 does not increase the set temperature of the indoor unit 11 corresponding to this indoor unit air conditioning area. Considering that there is no significant effect on the temperature sensed by the person in the area, the calculation result storage unit 27 stores the calculation result that the set temperature of the indoor unit 11 corresponding to this area is a temperature raised by 1 ° C. from the reference temperature. To do. Thereby, the energy consumption for the air conditioning by an air conditioning facility can be reduced.

  When the number of people in an indoor unit air conditioning area is small, the arithmetic processing unit 26 uses the set temperature of the indoor unit 11 corresponding to this indoor unit air conditioning area as a kind of comfort evaluation value in this area. (Predicted Mean Vote: Predicted Mean Thermal Sensation) The value may be calculated so as to spread from a comfortable range.

  For example, if the normal PMV value is controlled in the range of −0.5 to +0.5, the arithmetic processing unit 26 sets the PMV value to −0. The set temperature may be calculated so as to be in the range of 7 to +0.7 or −0.9 to +0.9. In addition, the arithmetic processing unit 26 may calculate the set temperature so that different comfort evaluation values spread from a comfortable range, not limited to the PMV value.

FIG. 8 is a diagram illustrating an example of cooperative control of the indoor units when the stay / absence information is changed by the dynamic detection unit of the air conditioning energy management system according to the first embodiment.
Fig.8 (a) shows the control result of the indoor unit 11 based on the stay / absence information of the indoor unit air-conditioning area shown in Fig. 5 (a). In this example, in the indoor unit air-conditioning areas a, c, and d, the cooling operation is controlled for the indoor units 11 corresponding to these areas assuming that a person stays, and there is no person in the indoor unit air-conditioning area b. Assuming that the indoor unit 11 corresponding to this indoor unit air-conditioning area is controlled to stop.
As a result of this control, as shown in FIG. 8 (a), the indoor unit air-conditioning areas a, c, d are at a suitable temperature, and the indoor unit air-conditioning area b is at a high temperature.

  And when the state of stay / absence detection by the movement detection unit 14 changes and, as shown in FIG. 8 (b), when the indoor unit air-conditioning area b changes from a state where no person is present, The arithmetic processing unit 26 stores a calculation result indicating that the operation of the indoor unit 11 b is started in the calculation result storage unit 27.

  Here, even if the operation of the indoor unit 11b is simply started, it takes a certain time for the temperature of the indoor unit air-conditioning area b to reach the set temperature F. It takes time to become. The same applies to the case where the number of people in this area increases while the control of the indoor unit 11 in the indoor unit air-conditioning area b is weakly cooled.

  Therefore, in the present embodiment, in addition to the operation of the indoor unit 11b, arithmetic processing is performed so that the temperature of the indoor unit air conditioning area b quickly reaches the set temperature until the temperature of the indoor unit air conditioning area b reaches the set temperature. The unit 26 stores, in the calculation result storage unit 27, calculation results indicating that the air volume of the air conditioning by the indoor units 11a and 11d adjacent to the indoor unit 11b is increased or the direction of the air is changed. As described above, by performing coordinated control of a plurality of adjacent indoor units 11, it is possible to shorten the time until a person in the indoor unit air conditioning area b becomes comfortable.

  Next, control of the outdoor unit 12 will be described. In the present embodiment, one outdoor unit is connected to a plurality of indoor units provided according to the air conditioning area, and a sufficient energy saving effect cannot be obtained simply by controlling the indoor unit 11, so the outdoor unit 12 is also controlled. Perform together.

  Based on the stay / absence information of each indoor unit air conditioning area or the number of people information determined in step S401, the arithmetic processing unit 26 determines the stay / absence of the outdoor unit air conditioning area or the number of people for each outdoor unit air conditioning area. This is performed (step S403).

As a first specific example of step S403, determination of stay / absence for each indoor unit air-conditioning area based on stay / absence information for each indoor unit air-conditioning area will be described.
FIG. 9 is a diagram illustrating an example of a determination result of stay / absence of an outdoor unit air-conditioning area based on stay / absence information for each indoor unit air-conditioning area of the air-conditioning energy management system according to the first embodiment.
As shown in FIG. 9 (a), if there is at least one area where a person stays among a plurality of indoor unit air-conditioning areas in a certain outdoor unit air-conditioning area, the arithmetic processing unit 26 is assigned to the outdoor unit air-conditioning area. Decide to stay. On the other hand, if no person is staying in any of the plurality of indoor unit air-conditioning areas in a certain outdoor unit air-conditioning area, the arithmetic processing unit 26 determines that no person is present in this outdoor unit air-conditioning area.

Next, as a second specific example of step S403, the determination of the number of persons for each indoor unit air conditioning area based on the number of persons information for each indoor unit air conditioning area will be described.
FIG. 10 is a diagram illustrating an example in which the number of people in the outdoor unit air conditioning area is calculated based on the number of people information for each indoor unit air conditioning area of the air conditioning energy management system according to the first embodiment.
The arithmetic processing unit 26 calculates the sum of the number of people in all the indoor unit air conditioning areas in a certain outdoor unit air conditioning area as the number of people in the outdoor unit air conditioning area. As shown in FIG. 10A, the number of indoor unit air conditioning areas a in the outdoor unit air conditioning area A is 6, the number of indoor unit air conditioning areas b is 0, and the number of indoor unit air conditioning areas c is 3 people. When the number of people in the indoor unit air conditioning area d is two, the arithmetic processing unit 26 calculates the sum of these 11 people as the number of people in the outdoor unit air conditioning area A.

  Next, for each outdoor unit air conditioning area, the arithmetic processing unit 26 operates / stops or limits the load on the outdoor unit 12 based on the stay / absence information or the number of people information in the outdoor unit air conditioning area corresponding to the outdoor unit air conditioning area. Calculate the value. The arithmetic processing unit 26 stores the calculation result in the calculation result storage unit 27.

The control set value output unit 28 reads out the calculation result from the calculation result storage unit 27 and outputs it as a control set value to the air conditioner control device 13 of the air conditioning system 1.
The air conditioner control device 13 controls the outdoor unit 12 in the air conditioning system 1 using the control set value output from the energy management device 2 (step S404). The arithmetic processing unit 26 repeats steps S403 and S404 for each outdoor unit air conditioning area.

  A first specific example of step S404 will be described. If a person is staying in a certain outdoor unit air-conditioning area, the arithmetic processing unit 26 stores a calculation result indicating that the outdoor unit 12 corresponding to this area is operated in the calculation result storage unit 27. In addition, if there is no person in a certain outdoor unit air conditioning area, the arithmetic processing unit 26 stops the outdoor unit 12 corresponding to this outdoor unit air conditioning area or sets the load limit value of this outdoor unit 12 to 0%. To do.

  Next, a second specific example of step S404 will be described. The arithmetic processing unit 26 determines the load limit value of the outdoor unit 12 corresponding to this area based on the number of people in a certain outdoor unit air conditioning area.

FIG. 11 is a diagram illustrating an example of the relationship between the number of people in the outdoor unit air-conditioning area and the load limit value in the air-conditioning energy management system according to the first embodiment.
As the number of people in a certain outdoor unit air-conditioning area decreases, the arithmetic processing unit 26 calculates a value obtained by gradually reducing the load limit value of the outdoor unit 12 from 100% and stores it in the calculation result storage unit 27. In the example shown in FIG. 11, when the number of persons in a certain outdoor unit air conditioning area becomes 10 or less, the arithmetic processing unit 26 reduces the load limit value of the outdoor unit 12 corresponding to this area to 75%. When the number of people in this outdoor unit air conditioning area becomes 5 or less, the arithmetic processing unit 26 reduces the load limit value of the outdoor unit 12 corresponding to this area to 50%. When the number of persons in the outdoor unit air conditioning area becomes one or less, the arithmetic processing unit 26 reduces the load limit value of the outdoor unit 12 corresponding to this area to 0%. Thereby, the energy consumption for an air conditioning can be reduced according to the number of people of an outdoor unit air-conditioning area.
Thus, energy consumption can be further reduced by controlling the outdoor unit 12 based on the stay / absence information and the number of people information for each outdoor unit air-conditioning area.

  The other system 3 may be a personal PC, a smartphone, a tablet terminal, or the like. In this case, the other system data is personal schedule information set by manual input using this system. In this case, the system model storage unit 24 stores position information of each individual who owns a personal PC, a smartphone, a tablet terminal, and the like.

  The arithmetic processing unit 26 determines the stay / absence of each individual for each predetermined detection area based on these pieces of information. The arithmetic processing unit 26 uses this determination result and the position information of each individual stored in the system model storage unit 24 to determine whether a person stays or is absent in each indoor unit air conditioning area or to calculate the number of persons. Do.

  As described above, in the second embodiment, the energy management device 2 cooperates with the other system 3 to determine stay / absence in each indoor unit air-conditioning area or calculate the number of people, thereby staying in the air-conditioning area. -The accuracy of absence determination and the calculation of the number of people can be improved. Thereby, control of the air conditioning system 1 can be performed more correctly.

(Third embodiment)
Next, a third embodiment will be described.
FIG. 13 is a block diagram illustrating an example of an air conditioning energy management system according to the third embodiment.
In 3rd Embodiment, in addition to the indoor unit 11 and the outdoor unit 12, it has the air blower 16 as an air-conditioning installation.

In order to optimally control the air conditioning system 1, the energy management device 2 uses the data obtained by the air conditioning system 1 of the air conditioning system 1 and uses the data obtained from the air conditioning system 1 to the indoor unit 11, the outdoor unit 12, and the blower 16. The control set value of is output. The control setting value of the blower 16 is the operation / stop of the blower 16, the air volume, the wind direction, and the like.

FIG. 14 is a diagram illustrating an example of an air conditioning system of an air conditioning energy management system according to the third embodiment.
In the example shown in FIG. 14, twelve fans 16 are installed in the target space 10.
The blowers 16a to 16l share the indoor unit air conditioning areas a to l to perform air conditioning. That is, for example, the blower 16a air-conditions the blower area a, the blower 16b air-conditions the blower area b, the blower 16c air-conditions the blower area c, and the blower 16d air-conditions the blower area d.

  In the example shown in FIG. 14, for the fan area a, the fan areas b, c, d, e, and f are adjacent to each other, and for the fan area g, the fan areas h, i, j, and k. , L are adjacent in a row. Each of the blower areas a, b, c, d, e, and f is adjacent to the blower areas g, h, i, j, k, and l on a one-to-one basis.

  Also, the area combining the blower areas a, b, and c corresponds to the indoor unit air conditioning area a, the area combining the blower areas d, e, and f corresponds to the indoor unit air conditioning area b, and the blower areas g, h, The area including i corresponds to the indoor unit air conditioning area c, and the area including the blower areas j, k, and l corresponds to the indoor unit air conditioning area d. This correspondence relationship is stored in the system model storage unit 24.

In the outdoor unit air-conditioning area to which each fan area corresponds, the six movement detectors 14a, 14b, 14c, 14d, 14e, and 14f are used to indicate whether a person stays or is absent in the movement detection area corresponding to each movement detector 14. The number of people is detected.
Next, operation | movement of the arithmetic processing part 26 of the energy management apparatus 2 is demonstrated.
FIG. 15 is a flowchart illustrating an example of a processing procedure performed by the air conditioning energy management system according to the third embodiment. This process is a process performed by the arithmetic processing unit 26 at a constant cycle.
First, the stay / absence determination or the number of persons is detected for each indoor unit air conditioner area from steps S401 to S402 described in the first embodiment, and the indoor unit 11 is controlled according to the detection result.

  Next, stay / absence determination or the number of persons is detected for each outdoor unit air conditioner area from steps S403 to S404 described in the first embodiment, and the outdoor unit 12 is controlled according to the detection result. .

Next, the arithmetic processing unit 26 reads out the stay / absence information or the number of people information for each movement detection area from the measurement data storage unit 23. Based on the read result, the arithmetic processing unit 26 determines stay / absence for each fan area or measures the number of people (step S501).
As a first specific example of step S501, determination of stay / absence for each fan area based on stay / absence information for each movement detection area will be described.
FIG. 16 is a diagram illustrating an example of a stay / absence detection result for each detection area and a stay / absence determination result for each fan area by the air conditioning energy management system according to the third embodiment.
Next, the correspondence between the movement detection areas of the movement detection units 14a to 14f and the blower areas a to l will be described.
The blower area a corresponds to the two dynamic detection areas facing the blower area g among the four dynamic detection areas of the dynamic detection unit 14a, and the blower area b corresponds to the remaining two dynamic detection areas of the dynamic detection unit 14a. To do.
The blower area c corresponds to two dynamic detection areas facing the blower area i among the four dynamic detection areas of the dynamic detection unit 14b, and the blower area d corresponds to the remaining two dynamic detection areas of the dynamic detection unit 14b. To do.
The blower area e corresponds to two dynamic detection areas facing the blower area k among the four dynamic detection areas of the dynamic detection unit 14c, and the blower area f corresponds to the remaining two dynamic detection areas of the dynamic detection unit 14c. To do.
The blower area g corresponds to two movement detection areas facing the blower area a among the four movement detection areas of the movement detection unit 14d, and the blower area h corresponds to the remaining two movement detection areas of the movement detection unit 14d. To do.
The blower area i corresponds to the two dynamic detection areas facing the blower area c among the four dynamic detection areas of the dynamic detection unit 14e, and the blower area j corresponds to the remaining two dynamic detection areas of the dynamic detection unit 14e. To do.
The blower area k corresponds to the two dynamic detection areas facing the blower area e among the four dynamic detection areas of the dynamic detection unit 14f, and the blower area l corresponds to the remaining two dynamic detection areas of the dynamic detection unit 14f. To do.
Information indicating these correspondences is stored in the system model storage unit 24.

  When determining stay / absence of each fan area, the arithmetic processing unit 26 selects one fan area for stay / absence determination among the fan areas. If there is at least one area where it is determined that a person stays among the plurality of movement detection areas corresponding to the selected fan area, the arithmetic processing unit 26 determines that a person stays in the determination target fan area.

  On the other hand, if there is no area where it is determined that a person stays in the plurality of movement detection areas corresponding to the selected fan area, the arithmetic processing unit 26 determines that there is no person in the fan area to be determined. . The arithmetic processing unit 26 repeats this determination for each of the fan areas.

In the example illustrated in FIG. 16A, the arithmetic processing unit 26 acquires a determination result from the air conditioning system 1 that a person stays in either of the two dynamic detection areas corresponding to the blower area a. The arithmetic processing unit 26 determines that a person stays in the blower area a as shown in FIG.
Further, in the example illustrated in FIG. 16A, the arithmetic processing unit 26 acquires a determination result from the air conditioning system 1 that a person stays in one of the two dynamic detection areas corresponding to the blower area b. The arithmetic processing unit 26 determines that a person stays in the blower area b as shown in FIG.
In the example illustrated in FIG. 16A, the arithmetic processing unit 26 acquires a determination result from the air conditioning system 1 that no person is present in any of the two movement detection areas corresponding to the blower area d. . Based on the determination result, the arithmetic processing unit 26 determines that no person is present in the blower area d as shown in FIG.
In this way, even if the classification of the fan area in the target space and the classification of the movement detection area for each movement detection unit 14 do not match, based on the movement detection result by the movement detection unit 14, The dynamics can be judged. That is, the stay / absence information and the number of people information determined by the movement detection unit 14 can be converted into the stay / absence information and the number of people information for each fan area. Thereby, it is not always necessary to provide the dynamic detection unit 14 for stay / absence detection or number detection for each fan area. That is, it is not necessary to match the classification of the fan area in the target space with the classification of the dynamic detection area of the dynamic detection unit 14.

Next, as a second specific example of step S501, the determination of the number of persons for each fan area based on the number of persons detected for each movement detection area by the movement detection unit 14 will be described.
FIG. 17 is a diagram illustrating an example of the result of calculating the number of people for each fan area based on the number of people information for each movement detection area by the air conditioning energy management system according to the third embodiment.
As illustrated in FIG. 17, the arithmetic processing unit 26 sets the sum of the number of persons in each movement detection area corresponding to the fan area as the number of persons in the fan area.

  In the example shown in FIG. 17A, the arithmetic processing unit 26 has a person staying in each of the two dynamic detection areas corresponding to the blower area a, and the number of people in these areas is two people and one person. Is obtained from the air conditioning system 1. The arithmetic processing unit 26 adds up the number of persons indicated by the determination result, and determines that the number of persons in the blower area a is three as shown in FIG.

  In the example illustrated in FIG. 17A, the arithmetic processing unit 26 has a person staying in one of the two dynamic detection areas corresponding to the blower area b, and the number of people in this area is one. Is obtained from the air conditioning system 1. The arithmetic processing unit 26 determines that the number of persons in the blower area b is one as shown in FIG. 17B based on the number of persons indicated by the determination result.

  In the example illustrated in FIG. 17A, the arithmetic processing unit 26 acquires a determination result from the air conditioning system 1 that the number of people in any of the two dynamic detection areas corresponding to the blower area d is zero. The arithmetic processing unit 26 determines that the number of people in the blower area d is 0 as shown in FIG.

  For the control of the blower 16, the arithmetic processing unit 26 calculates the operation / stop of the blower 16, the air volume, the wind direction, etc. for each blower tone area based on the determination result of stay / absence of the blower area or the determination result of the number of people. Then, the calculation result is stored in the calculation result storage unit 27.

The control set value output unit 28 outputs the calculation result stored in the calculation result storage unit 27 to the air conditioner control device 13 of the air conditioning system 1 as a control set value.
The air conditioner control device 13 controls the blower 16 in the air conditioning system 1 using the control set value output from the energy management device 2 (step S502). The arithmetic processing unit 26 repeats steps S501 and S502 for each of the fan areas.

For example, when the determination result that a person stays in a certain fan area is acquired from the air conditioning system 1, the arithmetic processing unit 26 stores the calculation result that the fan 16 corresponding to this fan area is operated in the calculation result storage unit 27. Remember.
In addition, when the calculation processing unit 26 obtains a determination result that there is no person in a certain blower area from the air conditioning system 1, the calculation processing unit 26 stores the calculation result indicating that the blower 16 corresponding to the blower area is stopped in the calculation result storage unit 27. Remember.

Moreover, when the determination result which shows the number of persons in a certain air blower area is acquired from the air conditioning system 1, the arithmetic processing part 26 calculates the air volume and the wind direction by the air blower 16 corresponding to an applicable air blower area based on this number of persons. The calculation result is stored in the calculation result storage unit 27.
FIG. 18 is a diagram illustrating an example of the amount of air blown by a blower according to the number of people in the air-conditioning area of the outdoor unit of the air-conditioning energy management system according to the third embodiment.
In the example shown in FIG. 18, at the time of cooling, when the number of people in a certain blower area is two or more, the arithmetic processing unit 26 says that the blower amount of the blower 16 corresponding to this area is “large”. The calculation result is stored in the calculation result storage unit 27.

  In addition, when the number of people in this blower area decreases to less than two, the arithmetic processing unit 26 reduces the air flow rate of the blower 16 corresponding to this blower area to the perceived temperature of the person in this blower area. Considering that there is no significant influence, the calculation result storage unit 27 stores the calculation result that the blower 16 of the blower 16 corresponding to this area is “small”.

The control set value output unit 28 reads out the calculation result from the calculation result storage unit 27 and outputs it as a control set value to the air conditioner control device 13 of the air conditioning system 1.
The air conditioner control device 13 controls the blower 16 in the air conditioning system 1 using the control set value output from the energy management device 2.
As described above, in the third embodiment, since the energy consumed by the blower 16 can be reduced, the energy consumed for air conditioning can be further reduced.

(Fourth embodiment)
Next, a fourth embodiment will be described.
In the fourth embodiment, the air conditioner is controlled based on the temperature distribution measured by the temperature measurement unit 15.
FIG. 19 is a flowchart illustrating an example of a processing procedure performed by the air conditioning energy management system according to the fourth embodiment. This process is a process performed by the arithmetic processing unit 26 at a constant cycle, for example, at least once per minute.
The arithmetic processing unit 26 reads the temperature measurement result for each temperature measurement area from the measurement data storage unit 23, and determines the temperature distribution of the target space based on the temperature measurement result (step S601).
A specific example of step S601 will be described. FIG. 20 is a diagram illustrating the correspondence between the temperature measurement area and the indoor unit air conditioning area by the air conditioning energy management system in the fourth embodiment.
In the example illustrated in FIG. 20, the temperature measurement areas of the temperature measurement units 15 d to 15 f are square areas. In addition, the temperature measurement areas of the temperature measurement units 15a to 15c, and g to i are rectangular areas obtained by cutting a square area as a temperature measurement area such as the temperature measurement units 15d to 15f into half.

  For the short side of the temperature measurement area of the temperature measurement unit 15a, the short side of the temperature measurement area of the temperature measurement unit 15b and the short side of the temperature measurement area of the temperature measurement unit 15c are adjacent to each other in a row. For the temperature measurement area of the temperature measurement unit 15d, the dynamic measurement area of the temperature measurement unit 15e and the temperature measurement area of the temperature measurement unit 15f are adjacent to each other in a row. For the short side of the temperature measurement area of the temperature measurement unit 15g, the short side of the dynamic detection area of the temperature measurement unit 15h and the short side of the temperature measurement area of the temperature measurement unit 15i are adjacent to each other.

The temperature measurement area of the temperature measurement unit 15d is adjacent to be sandwiched between the long side of the temperature measurement area of the temperature measurement unit 15a and the long side of the temperature measurement area of the temperature measurement unit 15g. The temperature measurement area of the temperature measurement unit 15e is adjacent so as to be sandwiched between the long side of the temperature measurement area of the temperature measurement unit 15b and the long side of the temperature measurement area of the temperature measurement unit 15h. The temperature measurement area of the temperature measurement unit 15f is adjacent to be sandwiched between the long side of the temperature measurement area of the temperature measurement unit 15c and the long side of the temperature measurement area of the temperature measurement unit 15i.
In the example shown in FIG. 20, the temperature measurement area of the temperature measurement unit 15a, the area adjacent to the temperature measurement area of the temperature measurement unit 15a among the temperature measurement areas of the temperature measurement unit 15d, and the temperature measurement area of the temperature measurement unit 15b. The area of the indoor unit air conditioning area is a combination of the area adjacent to the temperature measurement area of the temperature measurement unit 15a and one area adjacent to the temperature measurement area of the temperature measurement unit 15d among the temperature measurement areas of the temperature measurement unit 15e. corresponds to a. That is, these areas overlap with the indoor unit air conditioning area a.

  In addition, the temperature measurement area of the temperature measurement section 15c, the area adjacent to the temperature measurement area of the temperature measurement section 15c among the temperature measurement area of the temperature measurement section 15f, and the temperature measurement section 15c of the temperature measurement area of the temperature measurement section 15b. The area that combines the area adjacent to the temperature measurement area and the area adjacent to the temperature measurement area of the temperature measurement unit 15f out of the temperature measurement area of the temperature measurement unit 15e corresponds to the indoor unit air conditioning area b. That is, these areas overlap with the indoor unit air conditioning area b.

  Further, two temperature measurement areas of the temperature measurement unit 15g, an area adjacent to the temperature measurement area of the temperature measurement unit 15g among the temperature measurement areas of the temperature measurement unit 15d, and a temperature measurement of the temperature measurement area of the temperature measurement unit 15e. An area obtained by combining the area adjacent to the temperature measurement area of the unit 15d and the area adjacent to the temperature measurement area of the temperature measurement unit 15g among the temperature measurement areas of the temperature measurement unit 15h corresponds to the indoor unit air conditioning area c. That is, these areas overlap with the indoor unit air conditioning area c.

Further, two temperature measurement areas of the temperature measurement unit 15i, an area adjacent to the temperature measurement area of the temperature measurement unit 15i among the temperature measurement areas of the temperature measurement unit 15f, and a temperature measurement among the temperature measurement areas of the temperature measurement unit 15e. An area obtained by combining an area adjacent to the temperature measurement area of the unit 15f and an area adjacent to the temperature measurement area of the temperature measurement unit 15i among the temperature measurement areas of the temperature measurement unit 15h corresponds to the indoor unit air conditioning area d. That is, these areas overlap with the indoor unit air conditioning area d.
Information indicating these correspondences is stored in the system model storage unit 24.
The arithmetic processing unit 26 selects the temperature measurement units 15 connected in a row among the temperature measurement units 15 and determines a temperature distribution obtained by smoothly connecting the temperature measurement values measured by the selected temperature measurement unit 15.

FIG. 21 is a diagram illustrating an example of the temperature distribution of the target space in the air conditioning energy management system according to the fourth embodiment.
In FIG. 21, the temperature distribution obtained by smoothly connecting the temperature measurement value measured by the temperature measurement unit 15a, the temperature measurement value measured by the temperature measurement unit 15d, and the temperature measurement value measured by the temperature measurement unit 15g. a is shown.

Then, the arithmetic processing unit 26 operates / stops the indoor unit 11 based on the determination result of the temperature distribution, the set temperature, the air volume, Calculate wind direction.
The double sum of the error between the temperature measurement value and the set temperature is shown in the following equation (1).

T _i in the equation (1) indicates a temperature value measured by the temperature measurement unit 15 at the position i. T _i ^SET in Expression (1) indicates a set temperature by the indoor unit 11 at the position i. In the example shown in FIG. 21, the set temperature of the indoor units 11a and 11c is 26.0 ° C. N in Expression (1) corresponds to the number of temperature measurement units 15 related to one temperature distribution to be determined. For example, the temperature measuring unit 15 related to the temperature distribution a shown in FIG. 21 is assumed to be three temperature measuring units 15a, 15d, and 15g. The set temperature by the indoor unit 11 that air-conditions the installation position of the temperature measuring unit 15a is set to the set temperature of the indoor unit 11a close to the temperature measuring unit 15a. The set temperature by the indoor unit 11 that air-conditions the installation position of the temperature measurement unit 15g is set to the set temperature of the indoor unit 11c close to the temperature measurement unit 15g. Further, it is assumed that the set temperature by the indoor unit 11 that air-conditions the installation position of the temperature measuring unit 15d is either the set temperature of the indoor unit 11a or the set temperature of the indoor unit 11c.

  Specifically, in the temperature distribution a shown in FIG. 21, for example, the difference between the temperature value measured by the temperature measurement unit 15a and the set temperature of the indoor unit 11a is the same as the temperature value measured by the temperature measurement unit 15d and the indoor unit 11a. Or it is large compared with the difference with the preset temperature of 11c, and the difference of the temperature value measured with the temperature measurement part 15g, and the indoor unit 11c preset temperature.

  In this case, as a first example, the difference between the temperature value measured by the temperature measurement unit 15a and the set temperature of the indoor unit 11a is reduced, and the temperature value in the temperature measurement area of the current temperature measurement unit 15a is reduced. Then, in order to set the temperature distribution a to the temperature distribution b with reduced bias, the arithmetic processing unit 26 increases the air volume of the indoor unit 11a close to the temperature measuring unit 15a, or lowers the set temperature of the indoor unit 11a. Then, the operation result is obtained.

  However, if the difference between the temperature value measured by the temperature measurement unit 15a and the set temperature of the indoor unit 11a is reduced in this way, the temperature value measured by the temperature measurement unit 15d and the set temperature of the indoor unit 11a or the indoor unit 11c The difference and the temperature value measured by the temperature measurement unit 15g are also reduced, and the difference between the measured temperature value and the set temperature is increased.

  Therefore, as a second example, in order to set the temperature distribution to the temperature distribution c shown in FIG. 21, the arithmetic processing unit 26 increases the air volume of the indoor unit 11c close to the temperature measuring units 15d and 15g, A calculation result indicating that the set temperature of 11c is increased is obtained and stored in the calculation result storage unit 27. The temperature distribution c is a temperature distribution having a temperature value measured by the temperature measurement unit 15g higher than that of the temperature distribution b.

The control set value output unit 28 outputs the calculation result stored in the calculation result storage unit 27 to the air conditioner control device 13 of the air conditioning system 1 as a control set value.
The air conditioner control device 13 controls the indoor unit 11 in the air conditioning system 1 using the control set value output from the energy management device 2 (step S602). The arithmetic processing unit 26 repeats steps S601 and S602 for each of the areas corresponding to the temperature distribution to be determined. Thereby, since the bias of the temperature distribution in the indoor unit air conditioning area is reduced, the air conditioning in the indoor unit air conditioning area can be optimized.

  Here, as described above, even if control for reducing the bias of the temperature distribution related to the temperature measuring units 15a, 15d, and 15g is simply started, the temperature distribution is changed from the initial temperature distribution a to the temperature distribution b or the temperature distribution. It takes a certain time to reach c.

  Therefore, in the present embodiment, in addition to the control of the indoor unit 11 that is a normal control target, the predetermined time until the temperature distribution related to the temperature measurement units 15a, 15d, and 15g changes from the temperature distribution a to the temperature distribution b or the temperature distribution c. The arithmetic processing unit 26 outputs a calculation result regarding changes in the air volume and direction of the indoor unit 11b or the indoor unit 11d adjacent to the indoor unit 11a or the indoor unit 11c as a normal indoor unit to be controlled. In this way, by performing coordinated control of a plurality of adjacent indoor units 11, the time for eliminating the temperature distribution bias can be shortened, so that the temperature distribution bias in the indoor unit air conditioning area is reduced. Time can be shortened.

  In addition, when the temperature measurement value is missing due to a failure of some of the plurality of temperature measurement units 15 in the area corresponding to the temperature distribution to be determined, the arithmetic processing unit 26 Is a temperature measurement value by the temperature measurement unit 15 that is out of order using a temperature measurement value measured by another temperature measurement unit 15 adjacent to the temperature measurement unit 15 that is out of order. May be obtained as an interpolation value, and by using this interpolation value, a temperature measurement value by the temperature measurement unit 15 that has failed may be obtained.

  As described above, in the fourth embodiment, the indoor unit 11 is controlled so that the error between the temperature measurement value in the target space and the set temperature is reduced, so that the bias of the temperature distribution in the target space is reduced. can do.

  When the failure detection unit (not shown) detects that the indoor unit 11 or the blower 16 to be controlled according to each embodiment has failed, the arithmetic processing unit 26 separates another air conditioning facility adjacent to the failed air conditioning facility. The calculation result regarding the change of the air volume and the wind direction may be output. Thus, since the air conditioning which the faulty air conditioning equipment has shared can be shared by the adjacent air conditioning equipment, the air conditioning by the faulty air conditioning equipment can be continued.

  According to at least one embodiment described above, it is possible to perform air-conditioning control for reducing energy consumption without directly detecting the movement of a person in a plurality of air-conditioning areas subject to air-conditioning control for each air-conditioning area. An air conditioning energy management system, method, and program can be provided.
