Description of Embodiments

There are described hereinafter embodiments of the invention with reference to the accompanying drawings.

First Embodiment

A first embodiment of an air-conditioning management system according to the invention is described with reference to Figs. 1, and 2. Fig. 1 is a view showing an overall configuration of the air-conditioning management system, and the air-conditioning management system 1 is provided with a centralized controller 2 for managing a plurality of air conditioners. The centralized controller executes display and setting of respective operation states of air-conditioner groups A1, A2, ... (in Fig. 1, only A1, A2 are shown; however, the number of the groups may be not less than three). More specifically, plural indoor units 4 (4,..., 4n) are handled as a group A1, A2,... on a room-by-room basis, on a floor-by-floor-basis, and so forth to be thereby controlled. The respective air-conditioner groups are made up such that the plural indoor units 4 (4, ..., 4n) connected to, for example, one remote-control switch 5 are integrated with each other, and monitoring and controlling of the plural indoor units 4 can be executed in a batch.
Further, a plurality of the groups A1, A2,... integrated with each other, are handled as an air conditioner block (hereinafter referred to as a block) . In Fig 1, only the block A is shown, however, not less than two blocks (the blocks B, C, D,...) can be connected to one controller, that is, the centralized controller 2.
Plural outdoor units 3, the plural indoor units 4, a regeneration unit 7, the remote-control switch (hereinafter referred to simply as "remote control") 5, and so forth are connected to the centralized controller 2 via a control wiring 6.
Fig. 2 is a control block diagram of the air-conditioning management system according to the present embodiment. The centralized controller 2 includes a communication subunit 2a, a control subunit 2b, an input subunit 2c, a controller display subunit 2d, and a storage subunit 2e. The indoor unit 4 is provided with a control subunit 4b, and a communication subunit 4a for use in communication with the centralized controller 2, the outdoor unit 3, and the remote control 5, respectively. The outdoor unit 3 is provided with a communication subunit 3a for use in communication with the communication subunit 4a, and a control subunit 3b. The remote control 5 is provided with not only a communication subunit 5a for use in communication with the communication subunit 4a, but also a control subunit 5b, an input subunit 5c, a display subunit 5d, and a storage subunit 5e.
The control subunit 2b of the centralized controller 2 transmits an operation-instruction demand (change in operation mode, set temperature, and so forth) from the input subunit 2c to the indoor unit 4 via the control wiring 6 from the communication subunit 2a. The operation-instruction demand is received by the communication subunit 4a, whereupon the operation-instruction demand is executed by the control subunit 4b. After the execution, the control subunit 4b of the indoor unit transmits changed data to the centralized controller 2 via the communication subunit 4a, and the control wiring 6. The communication subunit 2a of the centralized controller 2 receives the changed data from the communication subunit 4a of the indoor unit, thereby displaying the contents of a change on the controller display subunit 2d. Further, the changed data is also transmitted from the communication subunit 4a of the indoor unit to the outdoor unit 3, and the remote control 5, respectively.
Transmission of an operation-instruction demand from the remote control 5 as well can be made to the indoor unit 4, and this operation-instruction demand from the remote control 5 is transmitted to the communication subunit 4a of the indoor unit 4 via the communication subunit 5a of the remote control, and the control wiring 6. In the case of the operation-instruction demand received from the remote control 5, changed data is also transmitted to the centralized controller 2, and the outdoor unit 3 via the communication subunit 4a of the indoor unit 4, and the control wiring 6.
Further, communication is performed between the indoor unit 4 and the centralized controller 2 every time operation data is changed, or at a given time interval, and the centralized controller 2 retains information on an operation between the outdoor unit 3 having received the operation data from the indoor unit 4, and the indoor unit 4, and so forth in the storage subunit 2e. By so doing, information (operation-information, group name, and so forth) on the respective air-conditioner groups A1, A2, ... can be displayed on the controller display subunit 2d to be thereby ascertained.
Next, there is described hereinafter an example of display at the controller display subunit 2d according to the present embodiment with reference to Figs. 3 - Figs. 18.
Fig. 3 shows a top screen that is normally displayed by the centralized controller 2. In the figure, 8a denotes a group icon corresponding to an individual air-conditioner group, and 8b denotes a block icon corresponding to individual air conditioner block categorized by the plural air-conditioner groups. The name of the individual air-conditioner group is displayed in the group icon, and the name of the individual air conditioner block is displayed in the block icon.
In the case of this example, four blocks including A block (1F Center), B block (1F Conference Room), C block (1 F Office) and D block (2 F Tenant) are displayed in the block icon 8b. The respective blocks include at least one group of the air-conditioner group, and the respective group icons 8a of the air-conditioner groups included in each of the blocks are displayed under each of the block icons. More specifically, the icons such as the group icons A1 (the air-conditioner group for air-conditioning of the general affairs dept.), A2 (the air-conditioner group for air-conditioning of the accounting business dept. ) , ... and so forth are disposed under the block icon A for the purpose of display.
Similarly, the group icons B1 (the air-conditioner group for air-conditioning of Conference Room 1), B2 (the air-conditioner group for air-conditioning of Conference Room 2), ..., and so forth are disposed under the block icon B, the group icons C1 (the air-conditioner group for air-conditioning of Office 1), C2 (the air-conditioner group for air-conditioning of Office 2), ..., and so forth are disposed under the block icon C, and the group icons D1 (the air-conditioner group for air-conditioning of Tenant 1A), D2 (the air-conditioner group for air-conditioning of Tenant 1B), ..., and so forth are disposed under the block icon D, respectively.
The respective group icons 8a are made up so as to be displayed in respective colors different from each other for every run/stop.
In the case where there exists not less than one group of the groups including at least one indoor unit 3 (4) where "regeneration operation," "inspection required," "operation under restriction," "filter cleaning required," "timer setting," and so forth are applicable, or at least one regeneration unit 7, or all the indoor units 4 connected to the centralized controller 2 are under setting of "remote control operation prohibited," a various-information icon 8c is displayed in the upper part of the controller display subunit 2d. Date and time are also displayed in the upper part of the controller display subunit 2d.
Further, a detail-display button 8d, a menu button 8j, a button 8k for all-groups setting in a batch, a button 81 for all-groups operation in a batch, and a button 8m for all the-groups stop in a batch are displayed in the lower part of the controller display subunit 2d.
With a push of the detail-display button 8d, the top screen 8 is switched to a detailed information 1 display screen 9. There are available two different methods for switching between detailed information display screens thereafter.
With one of the methods, after the information display screen is switched to the detailed information 1 display screen 9, the detail-display button 8d, a top button 8g, and the button 8k for all-groups setting in a batch are displayed in the lower part of the controller display subunit 2d, as shown in Fig. 4. As shown in a flow chart of Fig. 15, display is sequentially switched from [the detailed information 1 display screen 9 → a detailed information 2 display screen 10 → ... → a detailed information n display screen 20 → the top screen 8] at the time of every push of the detail-display button 8d. As the top button 8g is provided, it is possible to cause any detail-display screen to revert to the top screen 8.
With the present embodiment, the detailed information 1 display screen 9 is an operation-mode display screen shown in Fig. 4. With a push of the detail-display button 8d in this operation-mode display screen 9, an immediately following detailed information screen is displayed (if the immediately following screen is the top screen, the top screen is displayed) . Further, with a push of the top button 8g, the operation-mode display screen 9 is caused to revert to the top screen. More specifically, as shown in the flow chart of Fig. 15, with the push of the top button 8d on the top screen 8 shown in Fig. 3, there occurs a transition to the detailed information 1 display screen 9 (the operation-mode display screen), and with a push of the detail-display button 8d again, the detailed information 1 display screen 9 is switched to an immediately successive detailed information 2 display screen 10 (in this example, to a set-temperature display screen shown in Fig. 5) . Thereafter, at the time of every push of the detail-display button 8d, a detailed information display screen undergoes a transition to the next detailed information display screen, and with a push of the detail-display button 8d in the detailed information n display screen 20, the detailed information n display screen 20 is caused to revert to the top screen 8. Further, with the push of the detail-display button 8d in any of the detailed information display screen, any detailed information display screen can be reverted to the top screen 8.
With another of the methods, after the information display screen is switched to the detailed information 1 display screen 9, a preceding information button 8e, a following information button 8f, the top button 8g, and the button 8k for all-groups setting in a batch are displayed in the lower part of the controller display subunit 2d, as shown in Fig. 6. By so doing, display is sequentially switched from [the detailed information 1 display screen 9 → the detailed information 2 display screen 10 → ... → the detailed information n display screen 20 → the top screen 8] at the time of every push of the following information button 8f, as shown in a flow chart of Fig. 16. Further, since the top button 8g is provided, it is possible to cause any detailed information display screen to revert to the top screen 8.
With this example as well, the detailed information 1 display screen 9 is similarly the operation-mode display screen shown in Fig. 4. With a push of the following information button 8f in this operation-mode display screen 9, the immediately following detailed information screen is displayed (if the immediately following screen is the top screen, the top screen is displayed) and a push of the preceding information button 8e, an immediately preceding detailed-information screen is displayed. Further, with the push of the top button 8g, the operation-mode display screen 9 is caused to revert to the top screen. More specifically, as shown in the flow chart of Fig. 16, with a push of the detail-display button 8d in the top screen 8 shown in Fig. 3, there occurs a transition to the detailed information 1 display screen 9 (the operation-mode display screen), and subsequently, with a push of the following information button 8f, the detailed information 1 display screen 9 is switched to an immediately following detailed information 2 display screen 10 (the set-temperature display screen shown in Fig. 5) . Thereafter, at the time of every push of the following information button 8f, the detailed information 2 display screen 10 undergoes a transition to the next detailed information display screen, and with a push of the following information button 8f in the detailed information n display screen 20, the detailed information n display screen 20 is caused to revert to the top screen 8. Further, with a push of the preceding information button 8e, an immediately preceding detailed information screen can be displayed. Further, with the push of the preceding information button 8e in any of the detailed information display screen, any detailed information display screen can be reverted to the top screen 8.
Further, a configuration may be adopted such that if a button manipulation is not executed for a given time period after switching of the detailed information display screen, the screen is caused to automatically revert to the top screen 8.
With the present embodiment, with a push of the detail-display button 8d or the following information button 8f in the detailed information 2 display screen 10 (the set-temperature display screen shown in Fig. 5), the detailed information display screen is shifted to a fan speed display screen 11 shown in Fig. 6, and further, at the time of every push of the detail-display button 8d or the following information button 8f, the fan speed display screen 11 is sequentially switched to a wind-direction display screen 12 shown in Fig. 7, a maintenance-information display screen 14 shown in Fig. 10, a compressor operation-state display screen 15 shown in Fig. 11, and an air-conditioner accumulated operation-time display screen 16 shown in Fig. 12. Thus, with the present embodiment, at the time of every push of the detail-display button 8d or the following information button 8f, the detailed information display screen can be sequentially shifted to the following screens to thereby cause operation-information on all the air-conditioner groups to be displayed on one screen, so that it is possible to keep displaying any number of operation-information pieces that need be displayed. Furthermore, the respective icons of all the groups are displayed in a batch (the respective icons of all the groups are displayed on one screen) , and the icons of the respective groups are displayed at respective positions identical to each other, in the controller display subunit 2d, so that even if the screen is shifted to any of the detailed information screens, it is possible to instantly ascertain the operation-information on the air-conditioner group to be ascertained.
Next, there is described the contents of display on each of the detailed information display screens.
In the operation-mode display screen 9, the respective group icons 8a are displayed in colors differing from each other by the operation mode of each of the air-conditioner groups (with the present embodiment, the colors differing from each other are expressed by indicating the respective group icons 8a that are shown in differently textured half-tone dot meshing), as shown in Fig. 4. In the case of divergent operation modes (an operation mode as set from the centralized controller 2 differing from an operation mode actually in operation due to an operation cycle state of the outdoor unit 3) , both the operation modes are displayed. As shown by a divergent operation modes group icon 9a, "heating" according to an operation mode (the divergent operation modes) set from the centralized controller 2 is displayed in upper steps, and "cooling" according to the operation mode (a real operation mode) of the outdoor unit 3 actually in operation is displayed in lower steps by flashing light.
The set-temperatures of the respective air-conditioner groups are displayed on the set-temperature display screen 10, as shown in Fig. 5. A recommendable temperature can be preset, and it can be ascertained on the set-temperature display screen 10 that a set-temperature for the duration of a cooling operation is set lower than a recommendable cooling temperature or a set-temperature for the duration of a heating operation is set higher than a recommendable heating temperature. The recommendable cooling temperature and the recommendable heating temperature can be set on common screens as integrated after transition to a recommendable temperature setting screen 17 shown in Fig. 13 from the menu button 8j on the top screen 8 shown in Fig. 3.
In Fig. 5, if the set-temperature of an air-conditioner group for the duration of the cooling operation is set lower than a recommendable cooling temperature (28°C in this example), the group icon 8a of the air-conditioner group is displayed in a color different from a normal color. With a push of a recommendable cooling temperature setting button 8h on the screen of Fig. 5, the set-temperatures of an air-conditioner group, set lower than the recommendable cooling temperature, are forcefully changed to the recommendable cooling temperature (28°C) in a batch, whereupon the group icon 8a of the air-conditioner group whose set-temperature has been changed to the recommendable cooling temperature is displayed in the normal color.
Similarly, in Fig. 5, if the set-temperature of an air-conditioner group for the duration of the heating operation is higher than a recommendable heating temperature (20°C in this example), the group icon 8a of the air-conditioner group is displayed in a color other than the normal color, and the color in the case where the set-temperature is lower than the recommendable cooling temperature.
With a push of a recommendable heating temperature setting button 8i on the screen of Fig. 5, the set-temperatures of an air-conditioner group, set higher than the recommendable heating temperature, are forcefully changed to the recommendable heating temperature (20°C) in a batch, whereupon the group icon 8a of the air-conditioner group whose set-temperature has been changed to the recommendable heating temperature is displayed in the normal color.
With this example, if the set-temperature for the duration of the cooling operation is lower than the recommendable cooling temperature or the set-temperature for the duration of the heating operation is higher than the recommendable heating temperature, the group icon 8a is displayed in the color different from the normal color for the purpose of warning, however, the group icon 8a may be, for example, flashed instead of varying color for the purpose of warning to be thereby displayed.
Further, if the air-conditioner group that is forcefully changed in a batch by the recommendable cooling temperature setting button 8h or the recommendable heating temperature setting button 8i, and an air-conditioner group other than a target for a change in a batch are preset, this will enable flexible support matching the actual state of an area as a target for air-conditioning management.
A flow chart of a display method described in Fig. 5 is as shown in Fig. 17. More specifically, if the recommendable cooling temperature is set by the centralized controller 2 shown in Figs. 1, and 2, respectively, the set-temperature of a group is set lower than the recommendable cooling temperature, and the group icon 8a of the group as the target for the change in a batch is displayed in the color different from the normal color. Upon the recommendable cooling temperature setting button 8h shown in Fig. 5 being pushed in this state, the set-temperatures of all the groups as the targets for the change in a batch are forcefully changed to the recommendable cooling temperature, and the group icon 8a is displayed in the normal color, as shown in Fig. 17 (a). Similarly, if the recommendable heating temperature is set by the centralized controller 2 shown in Figs. 1, and 2, respectively, the set-temperature of a group is set higher than the recommendable heating temperature, and the group icon 8a of the group as the target for the change in a batch is displayed in the color other than the normal color, and the color in the case where the set-temperature is lower than the recommendable cooling temperature. Upon the recommendable heating temperature setting button 8i shown in Fig. 5 being pushed in this state, the set-temperatures of all the groups as the targets for the change in a batch are forcefully changed to the recommendable heating temperature, and the group icon 8a is displayed in the normal color, as shown in Fig. 17 (b) . The set-temperature can be switched over in display between Celsius temperature and Fahrenheit temperature (not shown).
With the fan speed display screen 11, the respective group icons 8a are displayed in colors differing from each other by the fan speed of each of the air-conditioner groups, as shown in Fig. 6.
On the wind-direction display screen 12 shown in Fig. 7, there is displayed a wind-direction angle of a blow-off air blew off from the indoor unit 4. With the present embodiment, the wind-direction angle can be set in 8 stages, and displays in the controller display subunit 2d are provided according to respective wind-directions that are set, as shown in Fig. 8. More specifically, the wind-direction in a first stage corresponds to an angle at which air is blew off in a direction closest to the horizontal direction, the wind-directions in second and third stages, respectively, gradually point more downward, and the wind-direction in a seventh stage corresponds to an angle at which the air is blew off in the most downward direction. Further, there is provided an auto wind-direction mode, which is a mode for causing the wind-direction to be automatically varied from the horizontal direction to downward or from downward to the horizontal direction. As shown in Fig. 7, the respective group icons 8a of the air-conditioner groups with a fixed wind-direction angle are displayed in a color differing from a color in which the respective group icons 8a of the groups where the auto wind-direction mode is set.
There is also provided an outdoor unit operation cycle display screen (not shown) for displaying the operation cycle state of the outdoor unit 3, and the operation modes (a cooling-operation mode, a heating-operation mode, an auto cooling/heating operation mode, a dry operation mode, and so forth) of the outdoor unit 3 are displayed on the outdoor unit operation cycle display screen. As is the case with the operation-mode display screen 9 shown in Fig. 4, the respective group icons 8a are displayed in colors differing from each other by the operation mode.
Upon the group icon 8a of an air-conditioner group, the block icon 8b, or the button 8k for all-groups setting in a batch being pushed on the operation-mode display screen 9 (Fig. 4), the set-temperature display screen 10 (Fig. 5), the fan speed display screen 11 (Fig. 6), the wind-direction display screen 12 (Fig. 7), and the outdoor unit operation cycle display screen (not shown), respectively, an operation-condition setting screen 13 shown in Fig. 9 is displayed in a pop-up fashion. With respect to a relevant air-conditioner group, block, or all the air-conditioner groups, setting of run/stop, setting of an operation mode, setting of a set-temperature, setting of an fan speed, setting of wind-direction, setting of remote control operation (permitted/prohibition), and a change in the contents of setting can be executed from the operation-condition setting screen 13.
If the respective air-conditioner groups apply to at least any of "regeneration operation," "inspection required," "operation under restriction (demand setting)," "filter cleaning required," "timer setting," and "remote control operation prohibited" on the maintenance-information display screen 14 shown in Fig. 10, the various-information icons 8c applicable to those information, respectively, are displayed in the respective group icons 8a, as shown in the figure. In such a case, the respective group icons 8a are displayed in various colors different from the normal color.
Besides the display screens described as above, there are provided detailed information screens including an inlet-temperature display screen, an ambient-temperature display screen, a remote control thermometer display screen, a remote thermometer display screen, and so forth, and respective temperatures are displayed as is the case with the set-temperature display screen 10 shown in Fig. 5. Temperature in the periphery of a remote control switch is displayed on the remote control thermometer display screen, and a mean value between the inlet-temperature and the reading of a remote thermometer is displayed on the remote thermometer display screen
In the case of the compressor operation-state display screen 15 shown in Fig. 11, if a compressor of the outdoor unit to which a relevant air-conditioner group is connected via piping is in operation, "thermo ON" is displayed, and if the compressor is in stop, "thermo OFF" is displayed. In the case of "thermo ON," relevant group icons 8a are displayed in a color different from the normal color.
In the case of the air-conditioner operation- time display screen 16 shown in Fig. 12, accumulated operation time of the indoor unit 4 of the relevant air-conditioner group, in, for example, a relevant month, is displayed as "such and such hours" or "such and such h" or "such and such H". In Fig. 12, guidance operation hours (in this example, 600 hours) can be preset, and if accumulated the operation time exceeds the guidance operation hours, the group icon 8a of the relevant air-conditioner group is displayed in a color different from the normal color.
In the case of the outdoor unit compressor's thermo-ON time display screen (not shown), compressor operation hours of the air-conditioner group connected to the outdoor unit, in the relevant month, are displayed as is the case with the air-conditioner accumulated operation-time display screen 16 shown in Fig. 12.
Fig. 13 shows the screen 17 for setting the recommendable cooling temperature, and the recommendable heating temperature, and a transition from the menu button 8j shown in Fig. 3 to the screen 17 is possible, thereby enabling the recommendable cooling temperature, and the recommendable heating temperature for all the air-conditioner groups to be set in a batch.
Further, it is also possible to effect transition from the menu button 8j shown in Fig. 3 to a detailed information display setting screen 18 shown in Fig. 14. With respect to displays on the detailed information display setting screens 9 to 16, and so forth, respectively, a multitude of items of the displays can be set, so that if all the detailed information display setting screens are sequentially displayed at all times, it is expected to take much time before reaching target information. Accordingly, the present embodiment is configured such that display items can be preset as appropriate so as to enable only necessary information according to an operator (a supervisor, service man, and so forth), operating the centralized controller 2, to be displayed on the detailed information display setting screen 18. More specifically, setting can be executed whereby detailed information 1, and detailed information 2 are displayed in "display mode 1" while detailed information 3 is displayed in "display mode 2" on the detailed information display setting screen 18.
For example, with respect to the operation-mode display screen 9 (Fig. 4), and the set-temperature display screen 10 (Fig. 5) on the detailed information display setting screen 18 shown in Fig. 14, display in "display mode 1" is selected with a push of a display mode 1 button 18a, while with respect to the inlet-temperature display screen, and the remote control thermometer display screen, display in "display mode 2" is selected with a push of a display mode 2 button 18b. Thus, necessity/non-necessity of displaying respective detailed information pieces can be selected for every display mode. By so doing, the operation-mode display screen 9, and the set-temperature display screen 10 can be sequentially displayed in "display mode 1," and the inlet-temperature display screen, and the remote control thermometer display screen can be sequentially displayed in "display mode 2".
Accordingly, there is available an application method whereby the display mode 1 is used as a monitoring mode to display the operation-mode, and the set-temperature while the display mode 2 is used as an inspection mode to display the inlet-temperature, and the remote control thermometer.
A flow chart of this operation is as shown in Fig. 18. Display or non-display with respect to the respective detailed information pieces 1, 2, ... is decided upon, and setting is made on whether detailed information to be displayed is displayed in the display mode 1, in the display mode 2, or in both the display mode 1 and the display mode 2. If the setting is made as above, the detailed information screens that are set so as to be displayed in the display mode 1 are sequentially displayed in the display mode 1 while the detailed information screens that are set so as to be displayed in the display mode 2 are sequentially displayed in the display mode 2, so that only necessary items according to the operator operating the centralized controller 2 can be sequentially displayed, thereby enabling the operator to reach the target information in short time.
Further, as to selection of the display mode, setting can also be made such that, for example, if the detail-display button 8d is pushed once on the screen of Fig. 3, the display mode 1 will occur, and if the detail-display button 8d is pushed for awhile, the display mode 2 will occur.
As described in the foregoing, with the present embodiment, the respective group icons 8a showing information on the air-conditioner group in whole are displayed at a given layout on one screen instead of displaying a wide variety of the detailed information (ascertainment of the operation-information such as the operation mode by the air-conditioner group, the set-temperature, and so forth, ascertainment of maintenance-information such as necessity/non-necessity of inspection, necessity/non-necessity of filter-cleaning, and so forth ) in one batch on the screen of the centralized controller 2 for managing the plural air conditioners, and the detailed information is switched to be displayed every time the button is pushed once while displaying the respective group icons 8a showing the operation-information on the air-conditioner group in whole at the given layout by one variety after another on one screen, so that different detailed information pieces can be sequentially displayed at respective positions identical to each other, thereby enabling an air-conditioning management system capable of easily ascertaining the respective varieties of the detailed information pieces on the air-conditioner group in whole to be implemented.
Further, after an operation state is displayed in the controller display subunit of the centralized controller, and the operation state is ascertained, it is possible to cause a setting-change screen to be displayed in the pop-up fashion as is the case with the operation-condition setting screen 13, so that the present embodiment has an effect that a setting-change can be instantly executed by a simple operation after ascertaining the operation state.
Further, since the respective varieties of the detailed information pieces are switched by one variety after another to be then displayed, the present embodiment has another effect that characters and figures, large in size, can be displayed.
Further, if an equipment requiring maintenance is included in even one of the air-conditioner groups on the top screen 8 shown in Fig. 3, a maintenance icon for "emergency stop, " "inspection required, " "filter cleaning required," and so forth, as the various-information icon 8c, is also displayed in the upper part of the controller display subunit 2d, so that it is possible to instantly find out which air-conditioner group requires maintenance if the top screen 8 is caused to undergo a transition to the maintenance-information display screen 14 shown in Fig. 10. Accordingly, the present embodiment has still another effect that remiss overlooking of maintenance-information can be prevented, and speedy maintenance can be performed.
Since respective temperatures set on an group-by-group basis can be instantly found out from the set-temperature display screen 10, the present embodiment has a further effect in that over-cooling and over-heating are prevented, and the centralized controller 2 can forcefully changes the set-temperature, thereby reducing energy consumption. Furthermore, not only general users such as a building supervisor and so forth can easily find out necessary operation-information but also a service worker responsible for maintenance of the air-conditioners can easily find out operation-information necessary at the time of an inspection.
Thus, with the present embodiment, it is possible to display the respective varieties of the detailed information pieces on the plural air-conditioner groups on the display subunit of the centralized controller in such a way as to enable an operator to easily ascertain the information pieces by a simple operation, so that it is possible to obtain an air-conditioning management system capable of easily getting hold of an air-conditioner group deviating from the setting of the air-conditioning management system, thereby instantly executing a setting-change.
