  Returning to FIG. 3, the program 43 is a computer program executed by the control unit 50, and includes an air conditioning control program 430, an energy saving group generation program 431, and an energy saving control program 432.

  The air conditioning control program 430 is a program that describes normal operation control for each air conditioner (outdoor unit 2, indoor unit 3). For example, the air conditioning control program 430 describes a process for displaying a monitoring screen and receiving a normal group designation and an operation instruction for a controlled air conditioner from the user via the monitoring screen. The air conditioning control program 430 describes a process for generating control data according to an operation instruction received from the user and transmitting the generated control data to each air conditioner belonging to the designated normal group. .

  The energy saving group generation program 431 is a program that describes processing for classifying indoor units 3 that are energy-saving controlled with the same content and generating an energy saving group different from the normal group. For example, the energy saving group generation program 431 describes a process for grouping the indoor units 3 based on the setting contents of the position management table 411.

  The energy saving control program 432 is a program describing energy saving control for the air conditioner. For example, the energy saving control program 432 describes a process for suppressing (decreasing) the operation capacity of the indoor unit 3 in units of energy saving groups with reference to the energy saving group information 421.

  Although not shown, the control unit 50 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The control unit 50 functionally includes an air conditioning control unit 51, an energy saving group generation unit 52, and an energy saving control unit 53. Each of these functions of the control unit 50 is realized by the CPU executing each of the programs stored in the data storage unit 40.

  The air conditioning control unit 51 executes processing based on the air conditioning control program 430. The air conditioning control unit 51 executes processing similar to that of this type of conventional system controller, for example, processing for controlling the operation of the air conditioner according to an operation instruction received from the user via the monitoring screen. In addition, when the air conditioning control unit 51 receives the data indicating the above-described operation state transmitted from the air conditioner via the communication unit 30, the operation state 4101 of the corresponding record in the control management table 410 based on the received data. Update the contents of.

  The energy saving group generation unit 52 executes processing based on the energy saving group generation program 431 (energy saving group generation processing). 8 and 9 are flowcharts showing the procedure of the energy saving group generation process. The energy saving group generation process is started when a predetermined operation is performed by the user via the operation reception unit 20 and the CPU of the control unit 50 executes the energy saving group generation program 431.

  First, the energy saving group generation unit 52 reads and refers to the position management table 411 stored in the data storage unit 40, and calculates the distance between each indoor unit 3 and another indoor unit 3 (step S101). ).

  The energy saving group generation unit 52 initializes the counter variables (i, j, k). More specifically, the energy saving group generation unit 52 substitutes the initial value “1” for i and j, and substitutes the value of j (ie, “1”) for k (step S102). Next, the energy saving group generation unit 52 selects the indoor unit 3 to be initially assigned (added) to the i-th energy saving group from the j-th normal group (step S103). For example, the energy saving group generation unit 52 selects a device that has not been assigned to any energy saving group and has the lowest device address. For example, in the first processing loop, the indoor unit 3a with the device address “001” is selected from the normal group 1.

  Next, the energy saving group generation unit 52 determines whether or not there is a k + 1-th normal group (step S104). When there is the k + 1th normal group (step S104; YES), the energy saving group generation unit 52 determines whether there is an unassigned indoor unit 3 in the k + 1th normal group (step S105). When there is an unassigned indoor unit 3 in the (k + 1) th normal group (step S105; YES), the energy saving group generation unit 52 is the i-th most recently assigned among the unassigned indoor units in the (k + 1) th normal group. For the indoor unit added to the energy saving group, the indoor unit installed at the most distant place is selected and added to the i-th energy saving group (step S106).

  When there is no unassigned indoor unit 3 in the (k + 1) th normal group (step S105; NO), or after the process of step S106, the energy saving group generation unit 52 increments k (step S107), and the process of step S104 Run again.

  If there is no k + 1-th normal group in step S104 (step S104; NO), the energy saving group generation unit 52 increments j (step S108 in FIG. 9). And the energy-saving group production | generation part 52 determines whether there exists a jth normal group (step S109). When there is the j-th normal group (step S109; YES), the energy saving group generation unit 52 determines whether there is an unassigned indoor unit 3 in the j-th normal group (step S110). When there is an unassigned indoor unit 3 in the j-th normal group (step S110; YES), the energy saving group generation unit 52 substitutes the value of j for k (step S111) and increments i (step S112). Then, the process of step S103 in FIG. 8 is executed again. On the other hand, when there is no unassigned indoor unit 3 in the j-th normal group (step S110; NO), the energy saving group generation unit 52 executes the process of step S108 again.

  When there is no j-th normal group (step S109; NO), the energy saving group generation unit 52 stores the processing result (information on the generated one or more energy saving groups) in the energy saving group information 421 of the data storage unit 40. (Step S113), and the energy saving group generation process is terminated.

  In FIG. 10, an example of the content of the energy saving group information 421 after reflecting the information about the energy saving group produced | generated by the above energy saving group production | generation process is shown. Moreover, when the content of the energy saving group information 421 shown in this example is represented on a plan view, it is as shown in FIG.

  Returning to FIG. 3, the energy saving control unit 53 executes processing based on the energy saving control program 432. The energy saving control unit 53 executes energy saving control for the purpose of power saving with respect to the air conditioner. In the present embodiment, when activated, the energy saving control unit 53 executes the energy saving control of the same content for all the indoor units 3 belonging to the energy saving group 1. And when predetermined time passes, the energy-saving control part 53 will perform the energy-saving control of the same content with respect to all the indoor units 3 which belong to the energy-saving group 2. FIG. When a predetermined time further elapses, the energy saving control unit 53 executes energy saving control of the same content for all the indoor units 3 belonging to the energy saving group 3.

  The energy-saving control unit 53 performs energy-saving control on the indoor unit 3 by rotating the energy-saving control target in units of energy-saving groups every predetermined time as described above until a predetermined condition for ending the energy-saving control is satisfied.

  For example, the energy-saving control unit 53 automatically performs the energy-saving control described above during a predetermined time period (9:00 to 17:00, etc.) on weekdays (Monday to Friday). Note that the energy saving control may be started or ended by a predetermined operation via the operation receiving unit 20 by the user.

  The energy saving control unit 53 performs energy saving control by suppressing (decreasing) the driving capability of the indoor unit 3. For example, the energy saving control unit 53 performs control such as changing the set temperature and operation mode of the indoor unit 3 to be controlled, or stopping the operation.

  Further, the specification may be such that the user can set the energy saving strength (for example, weak, medium, strong or weak) by a predetermined operation via the operation receiving unit 20. In this case, when the energy saving strength is weak, for example, the energy saving control unit 53 increases the set temperature of the indoor unit 3 to be controlled by 1 ° C. during the cooling operation and 1 ° C. during the heating operation. Further, when the energy saving strength is medium, the energy saving control unit 53 changes the operation mode of the indoor unit 3 to be controlled to, for example, the air blowing operation. Further, when the energy saving strength is strong, for example, the operation of the indoor unit 3 to be controlled is stopped.

  A specific example in the case of performing energy saving control by adjusting the set temperature of the indoor unit 3 to be controlled by 1 ° C. will be described with reference to FIGS. 12 and 13. FIG. 12 shows an example in which normal air conditioning control is performed by the air conditioning control unit 51 in units of normal groups. As can be seen from this figure, the indoor units 3a to 3c belonging to the normal group 1 are performing a cooling operation at a set temperature of 25 ° C. In addition, the indoor units 3d to 3g belonging to the normal group 2 perform a cooling operation at a set temperature of 26 ° C, and the indoor units 3h to 3j belonging to the normal group 3 perform a cooling operation at a set temperature of 24 ° C.

  FIG. 13 shows an example in which the energy saving control process by the energy saving control unit 53 is executed when the operation state of each indoor unit 3 is the above. In this example, it is shown that the set temperatures of the indoor units 3a, 3g, and 3h belonging to the energy saving group 1 are increased by 1 ° C. by the energy saving control.

  As described above, according to the system controller 1 according to the present embodiment of the present invention, each indoor unit 3 is grouped on the basis of the distance from the other indoor units 3, so that the normal group is Different energy saving control groups (energy saving groups) are generated and stored as energy saving group information 421. And at the time of execution of energy-saving control, energy-saving control is performed with respect to the indoor unit 3 not in the normal group but in the energy-saving group unit.

  Thereby, the bias | inclination of the energy saving strength between normal groups can be relieved. Therefore, in the air-conditioning target space corresponding to each normal group, appropriate energy saving of the air conditioner can be realized while maintaining comfort as much as possible.

(Embodiment 2)
Subsequently, Embodiment 2 of the present invention will be described. In addition, about the component etc. which are common in Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  FIG. 14 is a block diagram showing the configuration of the system controller 1A of the present embodiment. As can be seen from this figure, in the system controller 1A, a load management table 412 is newly added to the air conditioner information 41 in the data storage unit 40, and in the program 43, the energy saving group generation program 431 saves energy. It replaces the group generation program 431A. Further, as will be described in detail later, a plurality of energy saving group information 421 are stored corresponding to a plurality of predetermined time zones. And in the control part 50, the energy-saving group production | generation part 52 replaces the energy-saving group production | generation part 52A.

  In the system controller 1A of the present embodiment, the energy saving group generation method is different from that of the system controller 1 of the first embodiment. Hereinafter, a method for generating an energy saving group in the present embodiment will be described in detail.

  As shown in FIG. 15, the load management table 412 is a data table in which records including a device address 4120, a load 4121, and the like are registered for the number of installed air conditioners. The load management table 412 includes a plurality of predetermined time zones (for example, 9:00 to 10:00, 10: 00 to 11:00, 11: 00 to 12:00, 12: 00 to 13:00, 13). : 00 to 14:00, 14: 00 to 15:00, 15: 00 to 16:00, 16: 00 to 17:00, etc.).

  In the load management table 412 for each time zone, a communication address assigned to each indoor unit 3 is set in the device address 4120. In the load 4121, the value (relative value) of the air conditioning load of the indoor unit 3 in the time zone is set. FIG. 16 shows an example of setting contents of the load management table 412 in the time zone from 12:00 to 13:00. For example, this value is calculated based on the history of the air conditioning load of all the indoor units 3 in the time period. Various well-known statistical methods can be adopted as the calculation method. It should be noted that how to set the target history period is an arbitrary design matter. For example, the past week, month, year, etc. may be used. Further, the target history may be further narrowed down on weekdays, days of the week, and the like.

  The energy saving group generation program 431A is a program that describes a process of classifying indoor units 3 that are energy-saving controlled with the same content and generating an energy saving group different from the normal group. For example, the energy saving group generation program 431A describes a process for grouping the indoor units 3 based on the setting contents of the load management table 412.

  The energy saving group generation unit 52A executes processing (energy saving group generation processing) based on the energy saving group generation program 431A. 17 and 18 are flowcharts showing the procedure of the energy saving group generation process in the present embodiment. In the present embodiment, the energy saving group generation process is started by executing the energy saving group generation program 431A by the CPU of the control unit 50 at a predetermined time every day. In addition, you may make it start by performing predetermined operation via the operation reception part 20 by the user.

  First, the energy saving group generation unit 52A reads the load management table 412 for one time zone from the load management tables 412 for a plurality of time zones stored in the data storage unit 40 (step S201). For example, the energy saving group generation unit 52A sequentially reads from an early time zone.

  The energy saving group generation unit 52A refers to the read load management table 412 and calculates the difference in load between each indoor unit 3 and the other indoor units 3 (step S202).

  The energy saving group generation unit 52A initializes the counter variables (i, j, k). More specifically, the energy saving group generation unit 52 substitutes the initial value “1” for i and j, and substitutes the value of j (ie, “1”) for k (step S203). Next, the energy saving group generation unit 52A selects the indoor unit 3 to be initially assigned (added) to the i-th energy saving group from the j-th normal group (step S204). For example, the energy saving group generation unit 52A selects the one that has not been assigned to any energy saving group and has the smallest device address. For example, in the first processing loop, the indoor unit 3a with the device address “001” is selected from the normal group 1.

  Next, the energy saving group generation unit 52A determines whether or not there is a k + 1-th normal group (step S205). When there is the k + 1th normal group (step S205; YES), the energy saving group generation unit 52A determines whether there is an unassigned indoor unit 3 in the k + 1th normal group (step S206). When there is an unassigned indoor unit 3 in the (k + 1) th normal group (step S206; YES), the energy saving group generation unit 52A selects the i-th most recently assigned unassigned indoor unit in the (k + 1) th normal group. The indoor unit added to the energy saving group and the one with the largest load difference are selected and added to the i-th energy saving group (step S207). At this time, when there are a plurality of indoor units 3 having the largest load difference, the energy saving group generation unit 52A is installed at a place farthest from the indoor unit added to the i-th energy saving group most recently. Choose what you have.

  When there is no unassigned indoor unit 3 in the (k + 1) th normal group (step S206; NO), or after the process of step S207, the energy saving group generation unit 52A increments k (step S208), and the process of step S205 Run again.

  If there is no k + 1-th normal group in step S205 (step S205; NO), the energy saving group generation unit 52A increments j (step S209 in FIG. 18). Then, the energy saving group generation unit 52A determines whether or not there is a j-th normal group (step S210). When there is the jth normal group (step S210; YES), the energy saving group generation unit 52A determines whether there is an unassigned indoor unit 3 in the jth normal group (step S211). When there is an unassigned indoor unit 3 in the j-th normal group (step S211; YES), the energy saving group generation unit 52A substitutes the value of j for k (step S212), and increments i (step S213). Then, the process of step S204 in FIG. 17 is executed again. On the other hand, when there is no unassigned indoor unit 3 in the j-th normal group (step S211; NO), the energy saving group generation unit 52A executes the process of step S209 again.

  When there is no j-th normal group (step S210; NO), the energy saving group generation unit 52A adds the processing result (information about the generated energy saving group) to the energy saving group information 421 corresponding to the time zone in the data storage unit 40. Is stored (step S214). Then, the energy saving group generation unit 52A determines whether or not the above processing has been completed for the load management table 412 for all time zones (step S215). When the above process is completed for the load management table 412 for all time zones (step S215; YES), the energy saving group generation unit 52A ends the energy saving group generation process. On the other hand, when it is not completed (step S215; NO), the energy saving group generation unit 52A executes the process of step S201 in FIG. 17 again.

  FIG. 19 shows an example of the content of the energy saving group information 421 corresponding to the time zone from 12:00 to 13:00 after the above energy saving group generation processing. Moreover, when the content of the energy-saving group information 421 shown in this example is represented on a plan view, it is as shown in FIG.

  The energy saving control unit 53A refers to the energy saving group generated as described above, for example, in a predetermined time zone (9:00 to 17:00, etc.) on weekdays (Monday to Friday), and the same energy saving control as in the first embodiment. I do. At this time, in this embodiment, the energy saving control unit 53A reads the energy saving group information 421 corresponding to the current time zone from the data storage unit 40 and uses it every predetermined time (here, 1 hour).

  As described above, according to the system controller 1A according to the present embodiment of the present invention, by grouping the indoor units 3 based on the air conditioning load, a group for energy saving control (energy saving control) different from the normal group. Group) is generated and stored as energy saving group information 421. And at the time of execution of energy-saving control, energy-saving control is performed with respect to the indoor unit 3 not in the normal group but in the energy-saving group unit.

  The air conditioning load of the indoor unit 3 is also affected by the environment of the installation location. For example, in the cooling operation, the air conditioning load of the indoor unit 3 installed in the vicinity of the south-facing window side is the air conditioning of the indoor unit 3 installed in a place away from the window side (that is, a place not easily affected by solar radiation). It is known to be larger than the load. In addition, when installed near a heat source (for example, a server room) although it is installed in a place that is not easily affected by solar radiation, the indoor unit 3 installed in another place in the cooling operation. The air conditioning load is likely to be larger than

  For this reason, like the system controller 1A of this embodiment, the energy-saving control target is rotated in units of energy-saving groups generated based on the air conditioning load of each indoor unit 3, and energy-saving control is performed on the indoor unit 3. Thus, it is possible to alleviate the unevenness of energy saving strength among normal groups. Therefore, as in the case of the first embodiment, appropriate energy saving of the air conditioner can be realized while maintaining comfort as much as possible in the air conditioning target space corresponding to each normal group.

  In this embodiment, the relative value of the air conditioning load is set in the load 4121 of the load management table 412. However, it may be an absolute value.

  In addition, the air conditioning load set in the load 4121 is not limited to that calculated based on the history, and is, for example, an actual air conditioning load (relative value or absolute value) in the same time zone one day ago or one week ago. There may be.

  In addition, instead of generating energy saving groups corresponding to each time zone in a single process, the energy saving group generation unit 52A performs the processing at the start time of each time zone prior to the processing by the energy saving control unit 53. You may make it produce | generate only the energy-saving group corresponding to a time slot | zone.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to said each embodiment, Of course, the various change in the range which does not deviate from the summary of this invention is possible.

  For example, after the energy saving group is generated by the energy saving group generation units 52 and 52A, the user may be able to appropriately edit the energy saving group information 421 through the operation reception unit 20 or the like as necessary. In this case, a plan view as shown in FIG. 11 may be displayed on the display unit 10 so that the user can easily recognize the editing result. Moreover, when the indoor units 3 located in the vicinity are included in the same energy saving group during editing, the user may be notified in a predetermined manner (for example, message display or buzzer). Or audio output). Similarly, the normal group information 420 may be appropriately edited by the user.

  In each of the above embodiments, the energy saving group does not include the indoor units 3 of the same normal group. However, when there is a normal group including a large number of indoor units 3, the same energy saving group is used. A group may include a plurality of indoor units 3 belonging to the normal group.

  Further, in the energy saving group generation process, it is not always necessary to select the indoor units 3 one by one from all the normal groups, and it is not possible to select from the normal groups in which the air-conditioning target space is close (for example, adjacent). Good.

  Further, the degree of comfort deterioration (for example, increase in room temperature during cooling operation) due to the influence of energy saving control may be digitized, and an energy saving group may be generated using such a numerical value. In this case, for example, during a predetermined period from the start of operation of the present system, energy-saving control is performed using an energy-saving group in which the indoor units 3 are classified according to the distance from other indoor units 3 as in the first embodiment. In the meantime, the history of the degree of deterioration for each indoor unit 3 is stored. And after progress of a predetermined period, you may make it newly produce | generate and use an energy saving group by the method similar to Embodiment 2 using the history of the deterioration degree for every indoor unit 3 preserve | saved.

  Further, a block number 4112 may be added to the location management table 411 as shown in FIG. In the block number 4112, information (for example, a number) for identifying a block (for example, a floor) where the indoor unit 3 is installed is set. By doing in this way, a several energy saving group can be produced | generated individually per block (floor unit), and energy saving control can be performed.

  Further, the user may be able to determine whether or not the indoor unit 3 is under energy saving control via the remote controller 4. In this case, each indoor unit 3 has a normal instruction content holding area for storing instruction contents at the time of normal control and an energy saving instruction content holding area for storing instruction contents at the time of energy saving control in the memory provided in the own unit. Have

  In addition, each remote controller 4 has a function for acquiring, from a corresponding indoor unit 3, information indicating whether it is operating under normal control or energy-saving control and data including control instruction contents from a corresponding indoor unit 3. Each remote controller 4 has a function of displaying data acquired from the indoor unit 3 in a predetermined manner. Each remote controller 4 may acquire the above data all at once from all the corresponding indoor units 3, or from one or a plurality of indoor units 3 designated by the user among all the corresponding indoor units 3. Data may be acquired.

  In this way, by determining whether or not the indoor unit 3 is under energy saving control via the remote controller 4, the operation state of one (or some) of the indoor units 3 in the same normal group is different. If it does not match, it can be easily grasped whether or not it is due to energy saving control. For this reason, when a problem relating to comfort occurs, it is possible to prevent unnecessary inquiries to the facility manager and the like, and it is possible to save the trouble of checking with the system controllers 1 and 1A.

  Further, the application of the present invention is not limited to the facility management system for air conditioning. For example, the present invention can be applied to a system for lighting in an office building. In this case as well, as in the above embodiments, energy saving groups are generated by classifying according to the installation position and lighting load of each illuminator, and energy saving control (for example, illuminance) Lower or turn off the light.

  In addition, by applying each program executed by the system controller 1 or 1A to an existing personal computer (PC) or the like, the PC or the like can function as the system controller according to the present invention.

  The distribution method of such a program is arbitrary. For example, it can be read by a computer such as a flexible disk, a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), an MO (Magneto Optical Disk), or a memory card. It may be stored and distributed on a simple recording medium. Alternatively, the program may be stored in a disk device or the like included in a server device on a communication network such as the Internet, and the program may be distributed by superimposing the program on a carrier wave via the communication network. .

  In this case, when the functions according to the present invention described above are realized by sharing an OS (Operating System) and an application program, or by cooperation between the OS and the application program, only the application program portion is stored in a recording medium or the like. May be.
