Stored in “temperature” and “demand control on / off”.

  Therefore, each field of “room temperature” “humidity” “air flow” “operation state” “operation type” “power consumption” “set temperature” “demand control on / off” is described in the “time” field. Temperature of each target space at time, humidity of each target space, magnitude of air volume of each indoor unit 20a-20c, information on whether each indoor unit 20a-20c is in operation, each air conditioning unit 20a-20c is in cooling operation Or information on heating operation, power consumption value of each indoor unit 20a-20c, set temperature of each indoor unit 20a-20c, whether demand control (described later) is performed for each indoor unit 20a-20c Information on whether or not is stored.

  In particular, in the present embodiment, for convenience of explanation, information on the “demand control on / off” field indicating whether or not demand control is being performed (that is, on / off information), and each room during demand control Information on the “set temperature” field indicating the set temperatures of the units 20a to 20c is referred to as “demand control related information 45a”.

(3-3-2) Demand Control Database The demand control database 46 is a database used when a demand control unit 53 (described later) of the control unit 50 performs demand control on each of the indoor units 20a to 20c. FIG. 6 shows an example of the concept of the demand control database 46.

  Here, the demand control will be briefly described. Demand control is control which suppresses the power consumption which the air conditioner 10 (especially indoor unit 20a-20c) consumes. Specifically, the demand control means that a person who has contracted power with an electric power company (for example, an administrator of the building RA) is in contact with the electric power company by suppressing the maximum demand power of each of the indoor units 20a to 20c. It can be said that the control is to support the reduction of contracted basic power charges. The maximum demand power means the largest value in a month among the average power consumption every 30 minutes consumed by the indoor units 20a to 20c. The demand control operation will be described in detail in “(3-4-3) Demand control unit”.

  The demand control database 46 of FIG. 6 is a tabular database having a “suppression level” field of power consumption of each of the indoor units 20a to 20c and a “control content” field corresponding to each suppression level. In the “suppression level” field, the extent to which the power consumption of each of the indoor units 20a to 20c is suppressed is shown in stages in eight stages from level 1 to level 8. In the “control content” field, the degree of change in the set temperature of each of the indoor units 20a to 20c is indicated according to each suppression level. Specifically, in the “control content” field, content that the set temperature is changed by 1 ° C., content that is changed by 7 ° C., content that is forcibly thermo-off, and the like are stored.

  In FIG. 6, the degree of change in the set temperature of the indoor units 20a to 20c increases as the suppression level increases. Accordingly, when the “suppression level” field is “level 7”, the degree of change in the corresponding set temperature is larger than when the “suppression level” field is “level 1”. Furthermore, when the “suppression level” field is “level 8”, the corresponding “control content” field stores the content for forcibly turning off the thermostat instead of changing the set temperature.

  For example, when the indoor unit 20a is performing a cooling operation, if the “suppression level” field is “level 1”, the set temperature of the indoor unit 20a is set according to the content stored in the “control content” field. Increase by 1 ° C. If the “suppression level” field is “level 1” when the indoor unit 20a is performing a heating operation, the set temperature of the indoor unit 20a is 1 ° C. according to the contents stored in the “control content” field. Descend. If the “suppression level” field is “level 8”, forced thermo-off is executed according to the content stored in the “control content” field regardless of the operation type of the indoor unit 20a. “Forced thermo-off” refers to a state in which the compressor 31 of the outdoor unit 30 stops driving and heat exchange is stopped.

(3-3-3) Floor Plan Database The floor plan database 47 is information related to the floor plan of the target space, and is used when a screen generation unit 54 (described later) of the control unit 50 generates a screen to be displayed on the touch panel 43. Database. As shown in FIG. 7, the floor plan database 47 is a database having a plurality of hierarchical structures.

  In the floor plan database 47, various floor plans L1 relating to the building RA are stored. More specifically, the sketch L1 includes a schematic plan view L11 of the entire building RA and a schematic plan view L12 of the unit space constituting the building RA. In the floor plan database 47, the floor plan L1 including these schematic plan views L11 and L12 is hierarchically stored so as to correspond to the actual physical space structure of the building RA. That is, the schematic plan view L11 of the building RA is positioned at the top in the hierarchical structure of the floor plan database 47, and the schematic plan view L12 of the unit space is positioned below it.

  Here, the schematic plan view L12 of the unit space is image data illustrating walls, pillars, doors, windows, stairs, furniture (for example, desks and shelves), and the like. Two-dimensional coordinates are assigned to each point constituting the plan view of the unit space. Specifically, the unit space can be, for example, a room unit or a floor unit of the building RA.

(3-3-4) Position Information Database The position information database 48 is position information of each of the indoor units 20a to 20c in the building RA, and the screen generator 54 (described later) of the controller 50 is the same as the floor plan database 47. Is a database used when a screen to be displayed on the touch panel 43 is generated. FIG. 8 shows an example of the concept of the position information database 48.

  The position information database 48 of FIG. 8 is represented as a tabular database having “identification number”, “name”, “building”, “unit space”, and “coordinate” fields of the indoor units 20a to 20c. In the position information database 48 of FIG. 8, one record corresponds to one indoor unit 20a to 20c. That is, one record records the position information of one indoor unit 20a-20c.

  Specifically, an identification number for identifying each of the indoor units 20a to 20c is stored in the “identification number” field, and names of the indoor units 20a to 20c are stored in the “name” field. In the “building” field, the name of the building RA in which the indoor units 20a to 20c are installed is stored. The “unit space” field stores the name of the unit space in which one indoor unit 20a to 20c is installed. The “coordinate” field stores coordinate information based on the two-dimensional coordinates assigned to the sketch L1.

(3-3-5) Display Parts Database The display parts database 49 generates a screen to be displayed on the touch panel 43 by the screen generation unit 54 (described later) of the control unit 50, like the sketch database 47 and the position information database 48. It is a database used at the time. In FIG. 9, an example of the concept of the display parts database 49 is shown.

  The display parts database 49 of FIG. 9 is represented as a tabular database having “part number”, “part”, “part name”, “content”, and “display position” fields. Specifically, the “part number” field stores a number for identifying a part on each record. In the “parts” field, a picture actually displayed on the screen of the touch panel 43 is stored. In the “part name” field, the name of the picture stored in the “parts” field is stored. In the “content” field, the content represented by the picture stored in the “parts” field is stored. The “display position” field stores in which part on the screen the picture stored in the “parts” field is added and displayed.

  That is, the picture stored in the “parts” field on each record is displayed on the touch panel 43 as an icon representing the contents of the “content” field and at the position indicated in the “display position” field. .

  Specifically, as described later, the touch panel 43 displays a space layout screen sc1 in which device icons ic1, ic2, and ic3 indicating the indoor units 20a to 20c are arranged as shown in FIG. The pattern called “demand-on icon” in FIG. 9 (p1 in FIG. 13) is for the equipment indicating the indoor units 20a to 20c if there is an indoor unit 20a to 20c under demand control among the indoor units 20a to 20c. By being added to the lower right of the icons ic1 to ic3, they are displayed so as to overlap at least a part of the device icons ic1 to ic3. That is, the demand-on icon p1 constitutes on / off information (that is, information in the “demand control on / off” field of the device database 45) indicating whether or not demand control is being performed among the indoor units 20a to 20c. It can be said that it is an element to do. In addition, a picture called “demand control start icon” in FIG. 9 (p4 in FIG. 15) indicates that when demand control is started in at least one of the indoor units 20a to 20c, the manager is notified of that. As shown in FIG. 15, it is displayed in the lower right part of the touch panel 43.

(3-4) Control part The control part 50 is a microcomputer comprised by the combination of electrical components, such as ROM, RAM, and CPU. The CPU reads and executes various programs stored in the ROM, and the RAM is used as a work memory, so that the control unit 50 can perform various functions (for example, screen display control and air conditioning equipment 10) of the centralized management controller 40. Demand control, etc.) can be realized.

  Specifically, as shown in FIG. 4, the control unit 50 is connected to an air conditioning side communication unit 41, a network side communication unit 42, a touch panel 43, and a storage unit 44. The control unit 50 performs communication control of the communication units 41 and 42, management of various databases 45 to 49 stored in the storage unit 44, screen control of the touch panel 43, and the like. In order to perform such operations, the control unit 50 functions as a data collection unit 51, an operation control unit 52, a demand control unit 53, and a screen generation unit 54.

(3-4-1) Data Collection Unit The data collection unit 51 collects device data of the outdoor unit 30 and the indoor units 20a to 20c from the outdoor control unit 36 and the indoor control unit 25 at predetermined time intervals. The data collection unit 51 stores the collected device data in each field of the device database 45.

  That is, the data collection unit 51 updates the device database 45 shown in FIG.

(3-4-2) Operation Control Unit The operation control unit 52 manages the operation of the outdoor unit 30 and the indoor units 20a to 20c by sending operation commands to the outdoor control unit 36 and the indoor control unit 25, respectively. Control. For example, the operation control unit 52 causes the air conditioning side communication unit 41 to output a start instruction for cooling operation or a heating operation, an output of an operation stop instruction, an output of a set temperature of each indoor unit 20a to 20c, and the like.

(3-4-3) Demand control unit The demand control unit 53 performs demand control on each of the indoor units 20a to 20c.

  Here, the demand control operation performed by the demand control unit 53 will be described with reference to FIGS. First, the demand control part 53 extracts the power consumption of each indoor unit 20a-20c from the apparatus data of each indoor unit 20a-20c, and integrates | accumulates for every indoor unit 20a-20c. That is, the demand control unit 53 extracts the “power consumption” field of the device database 45 in FIG. 5 at predetermined time intervals at which the database 45 is updated, and integrates the extracted results. The demand control unit 53 obtains the degree of increase per unit time of the power consumption accumulated up to the present time for each of the indoor units 20a to 20c (the solid line portion in FIGS. 10 and 11), and reaches 30 minutes later according to the degree of increase. The power consumption that will be performed is predicted (dotted lines in FIGS. 10 and 11). Then, the demand control unit 53 compares the predicted power consumption with a predetermined target power consumption of each of the indoor units 20a to 20c, that is, an upper limit value of power that is allowed to be consumed.

  As shown in FIG. 10, when the predicted power consumption (dotted line portion) is lower than the target power consumption, the demand control unit 53 determines that demand control is not required for the indoor units 20a to 20c.

  However, as shown in FIG. 11, when the predicted power consumption (dotted line portion) exceeds the target power consumption, the demand control unit 53 determines that demand control is required for the indoor units 20a to 20c. . In this case, the demand control unit 53 uses the calculated degree of increase (solid line portion in FIG. 11) and the predicted power consumption (dotted line portion in FIG. 11) to suppress the power consumption of the indoor units 20a to 20c. Determine the suppression level. That is, the demand control unit 53 determines which level is selected from the levels 1 to 8 stored in the “suppression level” field of the demand control database 46 of FIG. Specifically, as the magnitude of the obtained increase degree is large and the difference between the predicted power consumption and the target power consumption is large, the demand control unit 53 has a relatively large suppression level (for example, level 5 in FIG. 6). Above). Conversely, the demand control unit 53 has a relatively low suppression level (for example, level 4 or lower in FIG. 6) as the obtained increase degree is smaller and the difference between the predicted power consumption and the target power consumption is smaller. Select.

  After selecting the suppression level, the demand control unit 53 applies the selected suppression level to the demand control database 46 of FIG. 6 to determine the control content. For example, when the suppression level “level 6” is selected, the control content is determined to shift the set temperature by 6 ° C. And the demand control part 53 shifts the preset temperature of applicable indoor unit 20a-20c based on the determined control content.

  In particular, when the corresponding indoor units 20a to 20c are performing the cooling operation, the demand control unit 53 shifts the set temperature of the corresponding indoor units 20a to 20c to the high temperature side according to the suppression level. Conversely, when the corresponding indoor units 20a to 20c are performing the heating operation, the demand control unit 53 shifts the set temperature of the corresponding indoor units 20a to 20c to the low temperature side according to the suppression level. Thereby, indoor unit 20a-20c by which preset temperature was changed does not need to consume electric power by that much.

(3-4-4) Screen Generation Unit The screen generation unit 54 generates various screens displayed on the touch panel 43.

-Space layout screen-
In particular, the screen generation unit 54 first generates a space layout screen sc1 of the target space shown in FIG. 12 as a screen on which the administrator can easily control and manage the indoor units 20a to 20c.

  Specifically, the screen generation unit 54 draws the target space sketch L1 from the floor plan database 47 in the storage unit 44 (specifically, the floor plan L11 of the building RA or the unit space sketch L12 to be displayed). Is read. The screen generation unit 54 reads out the coordinate information (specifically, information in the “coordinate” field) of the indoor units 20a to 20c installed in the target space from the position information database 48 in the storage unit 44. Then, the screen generation unit 54 arranges device icons ic1 to ic3, which are icons indicating the indoor units 20a to 20c, on the read sketch L1 according to the read coordinate information. Thereby, the space layout screen sc1 shown in FIG. 12 is generated.

-Composite screen-
Furthermore, the screen generation unit 54 according to the present embodiment generates the composite screen sc2 shown in FIG. 13 by combining the demand control related information 45a shown in FIG. 5 described above on the spatial layout screen sc1 once created. .

  Specifically, the screen generation unit 54 determines from the device database 45 in the storage unit 44 that the “demand control on / off” field of the indoor units 20a to 20c installed in the target space is “on” or “off”. To check. When there are indoor units 20a to 20c in which the “demand control on / off” field is “on”, the screen generation unit 54 reads from the display parts database 49 on the record whose “part name” field is “demand on icon”. The picture stored in the “parts” field is taken out. Then, as shown in FIG. 13, the screen generation unit 54 displays the demand-on icon p1 that is the extracted picture as an indoor unit 20a whose “demand control on / off” field is “on” on the space layout screen sc1. The device icons ic2 to 20c are arranged on the lower right side so as to overlap the icons ic2. Further, the screen generation unit 54 reads information on the “set temperature” field of the target indoor units 20 a to 20 c and information on the “operation type” field of the indoor units 20 a to 20 c from the device database 45. As shown in FIG. 13, the screen generation unit 54 arranges the read information p2 and p3 next to the corresponding device icons ic1 and ic2 in the space layout screen sc1. By this operation, the composite screen sc2 shown in FIG. 13 is generated. The screen generation unit 54 outputs the data of the created composite screen sc2 to the touch panel 43.

  That is, on the composite screen sc2 in FIG. 13, the on / off information included in the demand control related information 45a is configured by the demand on icon p1 indicating that the demand control is being performed. In the composite screen sc2, information p2 and p3 such as set temperatures of the indoor units 20a to 20c included in the demand control related information 45a are arranged in the vicinity of the device icons ic1 to ic3.

  By displaying the composite screen sc2 of FIG. 13 on the touch panel 43, the administrator grasps the layout in the building RA to be managed, particularly the air conditioning target space of the indoor units 20a to 20c. be able to. In particular, the administrator can see at a glance whether or not the indoor units 20a to 20c installed in the target space are currently under demand control by using the demand-on icon p1 on the composite screen sc2. It can be grasped only by.

  As described in “(3-4-3) Demand control unit”, the set temperature may be appropriately changed during demand control. Accordingly, the information in the “set temperature” field in the device database 45 is changed as appropriate. Accordingly, when a change occurs in various information in the device database 45, the screen generation unit 54 reflects the changed content on the composite screen sc2. That is, when the set temperature of the indoor units 20a to 20c is changed by demand control, the screen generation unit 54 appropriately updates the information p2 and p3 on the composite screen sc2.

  As a result, the administrator has already grasped the normal set temperature (specifically, the set temperature when demand control is not performed) and the information p2 and p3 (specifically, the composite screen sc2). From the difference from the set temperature information), it is possible to grasp how much demand control is performed.

  Further, the screen generation unit 54 displays the operation window bar b1 on the touch panel 43 so as to be selectable on the right side of the composite screen sc2 in FIG. When the operation window bar b1 is selected, the screen generation unit 54 causes the touch panel 43 to display the small screen sc3 on which the detailed information of the indoor units 20a to 20c on the composite screen sc2 is written, as illustrated in FIG. It is also possible. Here, the contents displayed on the small screen sc3 include the operating state of the indoor units 20a to 20c displayed on the composite screen sc2, the set temperature, the set air volume, and the like.

-Display position of composite screen and demand control start icon-
Next, where the above-described composite screen sc2 is arranged on the touch panel 43 will be described. As shown in FIG. 13, the touch panel 43 is mainly composed of two display areas surrounded by thick lines. One of the two display areas is a first display area re1 that is a relatively wide area, and the other is a second narrow and narrow second display area re2 that is located below the first display area re1. It is. The first display area re1 is an area in which a combined screen sc2 of the space layout screen sc1 and the demand control related information 45a is displayed. The second display area re2 is an area different from the first display area re1, and various tags for changing the screen displayed in the first display area re1 to another screen are always displayed. This is an area where information about the indoor units 20a to 20c can be displayed.

  Information related to the indoor units 20a to 20c displayed in the second display area re2 includes information notifying that when at least one of all the indoor units 20a to 20c installed in the building RA has failed. It is done. In particular, in the present embodiment, as shown in FIG. 15, the information about the indoor units 20 a to 20 c displayed in the second display area re <b> 2 includes the display parts described in “(3-3-5) Display parts database”. A pattern p4 of “demand control start icon” in the database 49 (hereinafter referred to as demand control start icon p4) is included. This is because the composite screen sc2 including the device icons ic1 to ic3 of the indoor units 20a to 20c for which demand control has been started is not displayed in the first display area re1, but another screen is displayed in the first display area re1. This is for promptly informing the administrator using the demand control start icon p4 that there are indoor units 20a to 20c for which demand control has been started.

  That is, when the administrator performs an operation for displaying FIG. 15 on the touch panel 43 from the state where FIG. 13 is displayed on the touch panel 43, the screen displayed in the first display area re1 of the touch panel 43 is as shown in FIG. It changes from 13 to FIG. In FIG. 13, the composite screen sc2 of the third floor in the building RA is displayed in the first display area re1, but in FIG. 15, the composite screen of the sixth floor, which is a target space different from the third floor. sc4 is displayed in the first display area re1. As described above, when an operation for displaying another screen is performed, the screen on the first display area re1 is changed, but the screen on the second display area re2 is not changed so much. Therefore, the screen generator 54 according to the present embodiment demands even one of all the indoor units 20a to 20c in the building RA to be managed, regardless of what screen is displayed in the first display area re1. If there is an item for which control has been started, a picture indicating that demand control has started, that is, a demand control start icon p4 is taken out from the display part database 49 of FIG. 9, and this is displayed in the second display area re2. In other words, the second display area re2 according to the present embodiment is not installed on the 6th floor shown by the composite screen sc4 (FIG. 15) currently displayed in the first display area re1, but other than the floor. When demand control is started with respect to the other indoor units 20a to 20c installed in, a demand control start icon p4 indicating that is displayed.

  Then, the screen generation unit 54 according to the present embodiment displays the demand control start icon p4 of FIG. 15 in a selectable manner. When the demand control start icon p4 is selected, as shown in FIG. 16, the screen generation unit 54 generates a message window p5 for notifying which indoor unit 20a to 20c the demand control is started. Is pop-up displayed in the first display area re1. Furthermore, in the message window p5, the names and identification numbers of the indoor units 20a to 20c for which demand control has been started are displayed so as to be selectable. When any one of the names and identification numbers of the indoor units 20a to 20c on the message window p5 is selected by the administrator, the screen generator 54 displays detailed information (room temperature, setting, etc.) of the selected indoor units 20a to 20c. Temperature, power consumption, etc.) are further displayed on the first display area re1. Note that the screen generation unit 54 may display the composite screen sc2 including the device icons ic1 to ic3 of the selected indoor units 20a to 20c in the first display area re1 instead of displaying detailed information. .

  In addition, in the first display area re1 according to the present embodiment, various screens can be displayed instead of the above-described composite screens sc2 and sc4. Examples of the screen displayed in the first display area re1 include a composite screen sc2, sc4, a list screen, an icon screen (both not shown), and the like. The list screen is a screen on which information such as the names, operation states, operation types, and room temperatures of the indoor units 20a to 20c displayed on the individual composite screens sc2 and sc4 is displayed as a list on one screen. The icon screen is a screen in which various icons used in the composite screens sc2, sc4, etc. are displayed in a list and a description of the contents of each icon is added. The composite screens sc2 and sc4, the list screen, and the icon screen can be defined as monitoring screens for the indoor units 20a to 20c.

  Further, in the first display area re1 according to the present embodiment, as shown as an example in FIG. 17, instead of the monitoring screens for the indoor units 20a to 20c that are the combined screens sc2 and sc4, the indoor units 20a to 20c are displayed. It is also possible to display a setting screen sc5 for automatically controlling. In the setting screen sc5 of FIG. 17, whether or not the set temperature control of each of the indoor units 20a to 20c is to be automatically controlled, and what schedule is to be used if it is to be automatically controlled, etc. The person can choose freely. Therefore, it can be said that the setting screen sc5 is a different screen type from the monitoring screens of the indoor units 20a to 20c.

  In this way, various screens can be displayed in the first display area re1, but as shown in FIGS. 15 to 17, the first display area re1 can display the first screen regardless of the type of screen displayed in the first display area re1. The demand control start icon p4 can always be displayed in the 2 display area re2. That is, at least one of the indoor units 20a to 20c in the building RA, even if any of the list screen and the icon screen that are monitoring screens other than the composite screens sc2 and sc4 is displayed in the first display area re1. When demand control is started, a demand control start icon p4 indicating that is displayed in the second display area re2. In particular, even when the setting screen sc5 that is not a monitoring screen is displayed in the first display area re1, when demand control is started in at least one of the indoor units 20a to 20c in the building RA, FIG. As shown in FIG. 4, the demand control start icon p4 is displayed in the second display area re2. As a result, the administrator starts the demand control on the second display area re2 based on the presence of the indoor units 20a to 20c for which the demand control has been started no matter what screen is displayed in the first display area re1. It can be grasped by the icon p4.

(4) Operation (4-1) When a composite screen or the like is displayed on the centralized management controller FIG. 18 illustrates a flow of operations performed by the centralized management controller 40 according to the present embodiment with the indoor units 20a to 20c. It is a figure for doing. In particular, FIG. 18 shows a case where the composite screen sc2 and the demand control start icon p4 are displayed on the centralized management controller 40 as an example.

  First, it is assumed that the centralized management controller 40 has already been activated.

  The centralized management controller 40 confirms the connection state with the indoor units 20a to 20c (# 1, # 2), and then starts an operation of collecting device data from the indoor units 20a to 20c at predetermined time intervals. (# 3, # 4).

  When the administrator requests display of the composite screen sc2, the screen generation unit 54 of the centralized management controller 40 first generates the space layout screen sc1, and combines the demand control related information 45a with this to generate the composite screen. Generate sc2 data. The touch panel 43 displays a composite screen sc2 as shown in FIG. 13 (# 5). At this time, if there are no indoor units 20a to 20c under demand control, a screen on which the demand-on icon p1 is not displayed from FIG. 13 is displayed.

  In addition, the demand control unit 53 of the centralized management controller 40 accumulates the power consumption of the indoor units 20a to 20c for each unit 20a to 20c, and uses the accumulated result or the like as 30 units as one unit. A total value of electric power that the individual indoor units 20a to 20c will consume is predicted (# 6). The demand control unit 53 determines whether or not it is necessary to start demand control of the indoor units 20a to 20c using the prediction result. Based on the determined content, the demand control unit 53 starts demand control including changing the set temperature of each of the indoor units 20a to 2c, or conversely stops demand control (# 7). Further, the demand control unit 53 updates the device database 45 in the storage unit 44 based on the determined content (# 8).

  Based on the determined content, the screen generator 54 updates the demand control related information 45a on the composite screen sc2 to generate a new composite screen sc2, and is displayed in the first display area re1 of the current touch panel 43. The composite screen is replaced with a new composite screen sc2. Alternatively, when the screen currently displayed on the touch panel 43 is a screen on which the indoor units 20a to 20c for which demand control has been started this time are not displayed, the screen generation unit 54 is placed on the second display area re2. The demand control start icon p4 is displayed so as to be selectable (# 9). In this state, when the icon p4 is selected, the screen generation unit 54 displays a message window p5 shown in FIG. 16 on the first display area re1 (# 10).

  Thereafter, the centralized management controller 40 repeats the operation of collecting device data from the indoor units 20a to 20c and the operations of steps # 6 to # 10.

(4-2) When a composite screen or the like is displayed on the external terminal FIG. 19 shows a centralized display when the composite screen sc2 and the demand control start icon p4 are displayed on the external terminals 90a and 90b instead of the centralized management controller 40. The flow of operation between the management controller 40 and the external terminals 90a and 90b is shown as an example.

  First, the user of the external terminals 90a and 90b operates the input units 92a and 92b of the external terminals 90a and 90b to start up a web browser on the external terminals 90a and 90b. Then, the user designates the URL of the central management controller 40 on the web browser and accesses the central management controller 40 (# 21). The central management controller 40 receives this (# 22), and sends a login screen to the web browser of the access source external terminals 90a, 90b (# 23). The login screen is a screen that prompts the user to input an ID and password for confirming the operation authority for the centralized management controller 40, and is displayed on the display units 91a and 91b of the external terminals 90a and 90b (# 24).

  When issuing the ID and password, the ID and password are stored in the storage unit 44 of the centralized management controller 40 in a state associated with the contents of the operation authority. The operation authority represents to what extent the central control controller 40 can be remotely controlled via the external terminals 90a and 90b. For example, in the case of the ID and password for the administrator of the building RA, the authority to permit management of all the indoor units 20a to 20c installed in the building RA is given as the operation authority. The operation authority may be an authority that permits management of only the indoor units 20a to 20c installed on some floors in the building RA. Further, the operation authority may be an authority not to change the set temperature of the indoor units 20a to 20c, or an authority to permit the stop and activation of the indoor units 20a to 20c only after an arbitrary time. it can.

  When the user inputs the ID and password via the login screen displayed on the display units 91a and 91b (# 25), the input ID and password are sent to the centralized management controller 40. The control unit 50 of the centralized management controller 40 identifies the operation authority corresponding to the sent ID and password (# 26), and creates an initial screen corresponding to the identified operation authority. The initial screen data is sent to the external terminals 90a and 90b (# 27) and displayed on the display units 91a and 91b of the external terminals 90a and 90b via the web browser (# 28).

  The initial screen may be a screen corresponding to the specified operation authority, or may be a screen provided with a link for transitioning to the combined screen sc2 of each floor in the building RA. For example, when the initial screen is a screen according to the operation authority, it can be the composite screen sc2 of the floor that can be managed by the user of the accessed external terminal 90a, 90b. When the initial screen is a screen provided with a link for transitioning to the composite screen sc2 of each floor, the user of the external terminals 90a and 90b selects the link corresponding to the floor to be confirmed, The composite screen sc2 of the floor can be displayed on the display units 91a and 91b of the external terminals 90a and 90b. That is, when a link is selected, a message to that effect is sent to the central management controller 40. The screen generation unit 54 of the centralized management controller 40 generates the composite screen sc2 of FIG. 13 in which the demand control related information 45a is added to the space layout screen sc1 of the floor corresponding to the selected link. Data is transmitted to the external terminals 90a and 90b.

  It is assumed that the centralized management controller 40 at least collects and manages device data from the indoor units 20a to 20c even during communication with the external terminals 90a and 90b. Then, the centralized management controller 40 performs power consumption prediction, demand control, update of the device database 45, and update of the composite screen sc2 as in Steps # 6 to # 9 of FIG. 18 (# 29, # 30). . When the composite screen sc2 is updated, new composite screen sc2 data is sent from the centralized management controller 40 to the external terminals 90a and 90b. In this case, the centralized management controller 40 displays the newly sent composite screen sc2 on the display units 91a and 91b (# 31).

  In addition, although not shown in FIG. 19, when the display instruction of the demand control start icon p4 is sent from the centralized management controller 40, the external terminals 90a and 90b, as shown in FIG. A demand control start icon p4 is displayed in a selectable manner on the display area re2. When the user selects the demand control start icon p4, a message to that effect is sent to the central management controller 40. The central management controller 40 generates data of the message window p5 shown in FIG. 16 and transmits it to the external terminals 90a and 90b. Also on the external terminals 90a and 90b side, a message window p5 is displayed on the first display area re1 as in FIG.

  Thereafter, the external terminals 90a and 90b and the centralized management controller 40 repeat the operation of collecting device data from the indoor units 20a to 20c and the operation after step # 27.

  Although not shown in FIG. 19, the external terminals 90 a and 90 b use the history of the device data of the arbitrary indoor units 20 a to 20 c and the control details of the centralized management controller 40 as history data. A transmission request can be sent to the centralized management controller 40. In this case, the centralized management controller 40 transmits history data regarding the corresponding indoor units 20a to 20c to the external terminals 90a and 90b in, for example, the CSV file format. Since the history data is in the CSV file format, the external terminals 90a and 90b can process the history data relatively freely. Therefore, the users of the external terminals 90a and 90b can efficiently manage the history data.

(5) Features (5-1)
A composite screen sc2 is displayed on the touch panel 43 of the centralized controller 40 according to the embodiment as shown in FIG. The composite screen sc2 is a space layout screen sc1 in which the device icons ic1 to ic3 are arranged on the target space sketch L1, and demand control related information indicating whether demand control is performed on the indoor units 20a to 20c. It is a synthetic | combination screen with the information 45a. By confirming the composite screen sc2, the administrator can easily grasp which indoor unit 20a to 20c is performing the demand control from the composite screen sc2.

(5-2)
Furthermore, in the centralized management controller 40 according to the embodiment, when demand control is started in at least one of the indoor units 20a to 20c installed in the building RA, as shown in FIG. A demand control start icon p4 indicating that demand control has been performed in at least one indoor unit 20a to 20c is displayed in a second display area re2 different from the first display area re1 in which sc2 is displayed. Thereby, even if the screen in which the device icons ic1 to ic3 of the indoor units 20a to 20c for which demand control is started is not displayed is displayed in the first display area re1, the administrator displays the second display. It can be understood from the demand control start icon p4 displayed in the area re2 that demand control has been started in at least one indoor unit 20a to 20c installed in the building RA.

(5-3)
In the second display area re2 of the touch panel 43 of the centralized controller 40, other indoor units 20a to 20c installed outside the target space indicated by the composite screens sc2 and sc4 currently displayed in the first display area re1 When demand control is started, a demand control start icon p4 indicating that is displayed. Specifically, as shown in FIG. 15, it is assumed that the composite screen sc4 of the sixth floor is displayed in the current first display area re1. In this state, when demand control is started in at least one of the indoor units 20a to 20c installed on another floor (for example, the third floor), the first display is displayed in the second display area re2. A demand control start icon p4 indicating the presence of the indoor units 20a to 20c for which demand control has been started on a floor different from the floor being displayed is displayed in the area re1. Thereby, the administrator can grasp | ascertain the demand control state of indoor unit 20a-20c in space other than the object space currently displayed on 1st display area re1 from 2nd display area re2. That is, the administrator does not monitor the demand control status of all the indoor units 20a to 20c in the building RA to be managed by frequently changing the composite screens sc2 and sc4 displayed in the first display area re1. It is only necessary to monitor whether or not the demand control start icon p4 is displayed in the second display area re2. Therefore, the convenience for the administrator is improved.

(5-4)
In addition, in the first display area re1 of the touch panel 43 of the centralized management controller 40, a setting screen sc5 can be displayed instead of the composite screens sc2 and sc4 as shown in FIG. On the other hand, no matter what screen is displayed in the first display area re1, if demand control is started in at least one of the indoor units 20a to 20c in the building RA to be managed, the second display area In re2, a demand control start icon p4 is displayed. Therefore, even when the administrator performs setting work for automatic control of the indoor units 20a to 20c via, for example, the setting screen sc5, the administrator determines the presence of the indoor units 20a to 20c for which demand control has been started. 2 can be grasped from the display area re2.

(5-5)
As shown in FIG. 5, the demand control related information 45a according to the present embodiment includes on / off information indicating whether or not demand control is being performed (specifically, “demand control on / off” in FIG. 5). Information stored in the field) and information on the set temperature of the indoor units 20a to 20c during the demand control (specifically, information stored in the “set temperature” field in FIG. 5). ing. As a result, the administrator can determine whether or not the indoor units 20a to 20c are under demand control and whether the set temperature of the indoor units 20a to 20c has been changed by demand control from the demand control related information 45a on the composite screen sc2. Whether or not can be grasped.

(5-6)
Further, as shown in FIG. 13, the on / off information includes a demand-on icon p1 indicating that demand control is being performed. The demand-on icon p1 is displayed so as to overlap with at least a part of the device icons ic1 to ic3. The set temperature information p2 and p3 of the indoor units 20a to 20c is arranged near the device icons ic1 to ic3. Thus, the administrator can visually confirm the demand-on icon p1 and the set temperature information p2 and p3 of the indoor units 20a to 20c by visually confirming the device icons ic1 to ic3. . Therefore, the administrator can grasp at a glance from the synthesized screen sc2 which indoor unit 20a to 20c is performing the demand control.

(5-7)
The centralized management controller 40 according to the present embodiment includes a network side communication unit 42. The network side communication unit 42 is communicably connected to the external terminals 90a and 90b via the communication network 80, and can transmit the data of the composite screen sc2 to the external terminals 90a and 90b. As a result, the user of the external terminals 90a and 90b accesses the centralized management controller 40 using the external terminals 90a and 90b, so that the composite screen sc2 of the demand control related information 45a and the space layout screen sc1 is displayed on the external terminal 90a. , 90b. Accordingly, it is possible to easily grasp which indoor unit 20a to 20c is performing the demand control not from the centralized management controller 40 but from the external terminals 90a and 90b.

(6) Modification (6-1) Modification A
In the synthesis screen sc2 according to the above-described embodiment, as shown in FIG. 13, set temperature information p2 and p3 included in the demand control related information 45a are displayed beside the device icons ic1 to ic3. However, in FIG. 13, it can be said that even an administrator can hardly grasp at a glance how much demand control is performed in detail.

  Therefore, in FIG. 13, the colors of the device icons ic1 to ic3 may be changed in accordance with the level at which demand control is performed (that is, the set temperature shift degree, specifically, the suppression level). For example, the color of the device icons ic1 to ic3 changes stepwise from blue to yellow and from yellow to red as the set temperature shift degree increases. Thereby, the administrator can grasp how much demand control is performed only by glance at the composite screen sc2 shown in FIG.

  Alternatively, in FIG. 13, the size of the device icons ic1 to ic3 itself may change according to the level at which demand control is performed, or the color change of the device icons ic1 to ic3 and the device icon Both the sizes of ic1 to ic3 may change.

(6-2) Modification B
Further, the level at which the demand control is performed (that is, the degree of shift of the set temperature, specifically, the suppression level) is represented on a trend graph showing the change over time in the room temperature as shown in FIG. Also good. FIG. 20 is a graph showing how the room temperature has changed over time, with time on the horizontal axis and room temperature on the vertical axis. FIG. 20 shows a period in which demand control is off, a period in which demand control is performed at the suppression level 3, and a period in which demand control is performed at the suppression level 6. The trend graph of FIG. 20 can be displayed on the touch panel 43 via a menu screen that is displayed when a menu list button such as FIG. 13 is selected.

  Thereby, the administrator can easily grasp the level at which the demand control is performed, that is, how much the set temperature has been shifted by the demand control, from the trend graph of FIG.

(6-3) Modification C
In the above embodiment, when demand control is started in at least one indoor unit 20a to 20c, a demand control start icon p4 indicating that is displayed in the second display area re2, as shown in FIGS. Explained.

It may change. For example, as the number of indoor units 20a to 20c for which demand control is started increases, the color of the demand control start icon p4 changes stepwise from blue to yellow and from yellow to red.

  Furthermore, a plurality of demand control start icons p4 displayed in the second display area re2 may be displayed separately for each target space (for example, floor units). For example, when demand control is started in the indoor units 20a to 20c installed on the third floor and the sixth floor, the demand control icon for the third floor and the demand control for the sixth floor The start icon may be displayed side by side in the second display area re2. Further, one demand control start icon p4 may be displayed in the second display area re2 for one indoor unit 20a to 20c. In this case, the number of demand control start icons p4 equal to the number of indoor units 20a to 20c for which demand control has been started is displayed in the second display area re2.

  In addition, when the indoor units 20a to 20c under demand control no longer exist, the demand control start icon p4 may be deleted from the second display area re2.

(6-4) Modification D
