Description

  The present invention relates to an air conditioner system including at least one outdoor unit and a plurality of indoor units. More specifically, the present invention relates to a control method and a centralized management apparatus for the air conditioner system.

  Conventionally, various types of centralized management devices that centrally control the entire air conditioner system have been disclosed. An example of this will be described with reference to the system configuration diagram of FIG. 1 and the block diagram of the centralized management apparatus of FIG. 1 and 2 is used in the present invention in the same configuration.

  As shown in FIG. 21, no. 22 indoor unit No. 22 to which the two outdoor units 12 and the remote controller 11 are respectively connected. 01-No. 10 indoor units 10, and a centralized management device 13 that centrally manages these outdoor units 12 and indoor units 10. These devices are connected by a signal line (communication line) of an air conditioner network that transmits and receives control signals to and from each other. Note that illustration and description of refrigerant pipes and the like not directly related to the contents of the present application are omitted.

  Each indoor unit 10 is classified into three groups corresponding to the place where these are installed. For example, a group control such as an office room or a conference room (not shown) performs collective control for each group when operation becomes easier than when individual indoor units 10 are controlled by the remote controller 11. It is also possible to perform collective control of the entire system. The central management apparatus 13 is an apparatus that instructs this collective control.

  As shown in FIG. 2, the centralized management apparatus 13 includes a display unit 1 composed of a liquid crystal display panel, an input unit 2 that is a touch panel arranged on the display surface of the display unit 1, and various devices connected to the system. Storage unit 4 that stores various management data as a management table, communication unit 5 that communicates with outdoor unit 12 and indoor unit 10 via an air conditioner network, display unit 1, input unit 2, storage unit 4, and communication unit And a control unit 3 for controlling the control unit 5.

  This centralized management device 13 inputs instructions to the system from the input unit 2 by an operation of an operator (not shown), displays the instruction data on the display unit 1, and displays these instructions via the communication unit 5. 12 and the indoor unit 10. The outdoor unit 12 or the indoor unit 10 that has received this instruction executes operation start / stop, determination of an operation mode such as cooling or heating, setting of a set temperature for the room in which the indoor unit 10 is installed, and the like according to the content of the instruction. . When executed in accordance with the instruction data, the latest operation state of the outdoor unit 12 or the indoor unit 10 is returned to the central control device 13 as operation state data. The central management device 13 updates the management table based on the returned operation state data.

  Further, data such as the room temperature of the room in which the indoor unit 10 is installed and the amount of air blown are transmitted from the indoor unit 10 to the centralized management device 13, and the centralized management device 13 stores the received data in the management table of the storage unit 4. And display on the display unit 1. On the other hand, the remote controller 11 determines only the indoor unit 10 to which the remote controller 11 is connected, starts / stops operation, determines the operation mode such as cooling or heating, and sets the temperature for the room in which the indoor unit 10 is installed. It is possible to instruct settings.

  All the instructions from the remote controller 11 are transmitted as data to the central management device 13 and stored in the management table of the storage unit 4, so that the central management device 13 can grasp the states of all the indoor units 10. Further, the operator can confirm the grasped state via the display unit 1 and can give any instruction to the indoor unit 10 of the entire system, the indoor unit 10 for each group, or the individual indoor units 10. .

  3 is a top view showing a floor plan of the building where the indoor unit 10 described in FIG. 1 is installed. FIG. 3 (A) shows the first floor of the building and FIG. 3 (B) shows the second floor of the building. This building has one window 6 for each room, and the windows 6 are arranged in the west direction or the east direction.

  In addition, there are rooms with room numbers 101 to 105 on the first floor of this building. One indoor unit 10 of 01 to 05 is installed. Similarly, there are rooms with room numbers 201 to 205 on the second floor of this building. One to ten indoor units 10 are installed one by one. Room numbers 104 and 105 are conference rooms. 04 and 05 are to be driven. Room numbers 101 to 103 are office rooms, and room numbers 201 to 205 are rental shops.

  FIG. 13 shows a management table stored in the storage unit 4, in which the states of the indoor unit 10 and the outdoor unit 12 are updated and stored in real time. This management table includes items defined at the time of system installation and items updated in normal operation.

  The items specified at the time of system installation include indoor unit No. (Outdoor unit No.), address, type, group, and room number. Indoor unit No. (Outdoor unit No.) is a number that physically distinguishes the indoor unit (outdoor unit), and the address is used to identify a communication partner in communication within the air conditioner network. The type is for specifying the type of equipment, for example, indoor unit and outdoor unit. As described above, when there are multiple different tenants in one building as described above, it is more efficient to control for each tenant. It is used in such cases. The room number is used so that the operator can easily see the place where the indoor unit is actually installed.

  Items updated in normal operation include power supply, operation mode, set temperature, room temperature, timer setting, air volume, and the like. The power source is the power on / off state of the target indoor unit, the operation mode is cooling / heating, etc. The set temperature is the target indoor temperature set for each indoor unit, the indoor temperature is the current room temperature, the timer setting is determined The settings for starting and stopping the operation at a given time, and the air volume indicate the strength of the indoor unit air flow during operation. As described above, these items are updated with the data received as a response to the instruction to each indoor unit from the central management apparatus 13 according to the instruction of the operator. Or the individual indoor unit setting information by operation of a remote control is transmitted to the centralized management apparatus 13, and the management table of the memory | storage part 4 is updated based on this. In addition to these timings, the indoor unit 10 may periodically transmit to the central management device 13.

  FIG. 14 is an example of a screen displayed on the display unit 1 of the central management device 13. The screen is roughly divided into a target area and a setting area. In the target area, the current state of the indoor unit can be confirmed. In this display area, the state of up to five indoor units can be displayed. Since there are a total of 10 indoor units in this system, the remaining 5 indoor units can be displayed by touching “Next Page”. If you want to see the previous indoor unit information, touch “Previous Page”.

  The setting area includes an area (frame) for setting a control target, an operation state, an operation mode, and a set temperature, and the setting contents are sequentially switched every time each area is touched. For example, “Individual”, “Group”, and “Overall” are switched in the control target area, “On”, “Off”, and “No change” are switched in the operating state area, and “Cooling” is switched in the operation mode area. , “Heating” and “No change” are switched.

  In the set temperature area, the center temperature display is incremented / decremented by 1 ° C. each time “+” and “−” arranged on the left and right are touched once. And indoor unit No. of an object area. When is touched, all the item columns of the corresponding indoor unit are yellow, and the selection target is selected. To cancel the selection, touch again to return to the original display state, and the selection is canceled. If you want to select multiple indoor units at the same time, touch the corresponding column in the same way.

  Indoor unit No. in the target area. After touching and selecting an indoor unit, when the “setting” area is touched, the contents selected in the setting area are transmitted as instruction data from the centralized management device 13 to the indoor unit selected in the target area. The indoor unit that has received this sets and operates the indoor unit according to the instruction data. Further, the contents set at the same time are transmitted from the indoor unit to the centralized management device 13, and the centralized management device 13 rewrites the management table in the storage unit 4 with the received data. The contents of this management table are redisplayed in the format shown in FIG. Therefore, FIG. 13 shows a state before transmission, but after the data is updated, the set temperature of the room number 102 changes from 25 ° C. to 28 ° C.

  FIG. 15 shows a screen when the control target is “group”. Since there are only three groups, all are displayed. For example, select group 1, set the operation state and operation mode to “No change”, set the temperature to 28 ° C., and touch the “Setting” area. . Then, the target device of group 1, that is, the indoor unit No. A set temperature of 28 ° C. is set for the devices 01 to 03.

  FIG. 16 shows a screen when the control target is “whole”. That is, the target is all indoor units, and all the devices in the target area (including other pages) are selected. Here, the operation state and the operation mode are set to “no change”, the set temperature is set to 28 ° C., and the “setting” area is touched. Then, all target devices, that is, indoor unit No. A set temperature of 28 ° C. is set for the devices of 01 to 10.

  Thus, the centralized management device 13 can grasp the states of all the indoor units 10 based on the data of the management table in the storage unit 4. In addition, the operator confirms the grasped state via the display unit 1, and gives an arbitrary instruction to the indoor unit 10 of the entire system, the indoor units 10 for each group, and the individual indoor units 10, and the storage unit The data of the management table 4 can be updated, and the status of all the indoor units 10 can be grasped as the latest data.

  By the way, apart from grasping the operation state of the indoor unit 10 by such a centralized management device 13, the operator has conventionally grasped the failure state of the two outdoor units 12 of the air conditioner system and the ten indoor units 10. It is carried out by patroling the installation location of each outdoor unit and indoor unit regularly or by checking the installation location by contact from the user. In order to eliminate such inconvenience for the operator, in recent years, there has been proposed a system in which the centralized management device 13 can grasp the operation states of a plurality of air conditioners and the failure states of the plurality of air conditioners.

  This centralized control device that centrally controls the entire air conditioner system receives failure status data of a plurality of air conditioners, stores the received failure status data in a storage unit, and performs air conditioning via a display unit. It is possible to grasp the failure status of the machine. Thereby, the operation state and failure state of the air conditioner can be grasped on the same screen of the display unit (see, for example, Patent Document 1).

  FIG. 17 shows a basic screen for air conditioning management displayed on the display unit of the centralized management apparatus of Patent Document 1. In the basic screen of air conditioning management on “Monday, September 25, 14:00”, the centralized monitoring display T2 displays whether all 55 air conditioners installed in the ABC building are “in operation”. Whether it is “stopped” or “failed” is displayed. That is, in FIG. 17, the air conditioner No. 35 is “failing” (indicated by dots), the air conditioners No. 17, 24, and 43 are “stopped” (indicated by double hatching), The remaining 51 of the 55 air conditioners are “running” (indicated by the left-down hatching).

  In addition, the “button 12” corresponding to the No. 12 air conditioner is touched (indicated by right-down hatching), and the air conditioner number display unit T11 and the operation / stop display unit T12 of the air conditioner information display unit T1 are ) It is displayed that the “12th” air conditioner installed in the ABC 4th floor office is “in operation”. In addition, the operation mode of No. 12 air conditioner is “cooling”, the air volume is “weak wind”, the louver is “ON”, the air conditioner suction temperature is “26.5 ° C.”, the set temperature is “25 ° C.”, etc. Each is displayed.

  The air conditioning management basic screen shown in FIG. 17 can be used to determine whether all the air conditioners are “operating / stopped / failed”, and by touching a predetermined air conditioner number, that air conditioner It is possible to grasp the operating state of.

  On the other hand, in the basic screen of air conditioning management shown in FIG. 17, it is displayed that the 35th air conditioner is “failing” as described above, and the “button 35” corresponding to the 35th air conditioner is displayed. When touched, as shown in FIG. 18, the basic screen for air conditioning management is displayed on the air conditioner number display portion T11 and the operation / stop display portion T12 of the air conditioner information display portion T1, and the fourth floor office room of ABC Corporation. The operation status of the “No. 35” air conditioner installed in the display is changed to the inspection details display, and “abnormal” is displayed for the No. 35 air conditioner on the centralized monitoring display T2, and further “inspection” “Code: 03” and “Filter jam” are displayed.

  This screen can be checked by the operator and appropriate measures can be taken. If the “confirmation button” is touched, the centralized management display unit T2 returns to the previous screen (in this case, the monitor screen of the No. 35 air conditioner). At this time, the air conditioner information display unit T1 displays the No. 35 air conditioner. Information is to be changed.

  However, in order to confirm the contents of the failure status data of the air conditioner, the operator touches the “button 35” of the No. 35 air conditioner indicating “failed” from the basic screen of air conditioning management in FIG. There is a problem that it is necessary to make a transition to the inspection content display, which not only takes time and effort, but also cannot be confirmed at a glance on the same screen of the air conditioning management. Moreover, although it changes to the inspection content display of FIG. 18 and can confirm the content of the failure state data of the 35th air conditioner, it cannot be confirmed simultaneously with the operation state of other air conditioners on the same screen of air conditioning management. There was a point.

Furthermore, although the contents of the failure state data of the No. 35 air conditioner can be confirmed by the inspection content display of FIG. 18, the air conditioner determines whether the “clogged filter” failure is a serious failure or a minor failure. There was a problem that the degree of machine failure could not be grasped intuitively. In addition, since the inspection content display of FIG. 18 shows only one No. 35 air conditioner, if the plurality of air conditioners are “failing”, the degree of failure of the plurality of air conditioners cannot be grasped. The operator cannot confirm at a glance on the same screen of the air conditioning management in order to deal with the failure, and there is a problem in that the serviceability of the failure is lowered.

At the same time, the failure states of the indoor unit 10 and the outdoor unit 12 are displayed independently. The configuration and operation of the centralized management device 13 for performing this display are summarized as follows.

  That is, the centralized management apparatus 13 described with reference to FIG. 2 displays the operation state data transmitted from the two outdoor units 12 and the ten indoor units 10 on the display unit 1. Further, the centralized management device 13 receives failure state data transmitted from the two outdoor units 12 and the ten indoor units 10 via the communication unit 5, and receives the failure state data under the control of the control unit 3. Is stored in the storage unit 4. Further, according to the control of the control unit 3, the failure state data is displayed independently of the operation state data and simultaneously with the failure state display format set in advance corresponding to the stored failure state data and stored in the storage unit 4. 1 is displayed.

  The failure state display format is set according to the importance of the failure state data. The degree of importance of the failure state data is represented by a failure level that is a numerical value representing a minor to severe failure stored in the storage unit 4 and a display color corresponding to the failure level. The failure state display format is, for example, a format for displaying the received failure state data in a display color corresponding to the failure level in combination with the failure level.

  Also, the importance of the failure state data is updated according to the number of occurrences of the same failure state data. Under the control of the control unit 3, the number of occurrences of the received failure state data is stored in another area of the storage unit 4, the failure level is upgraded based on the stored number of occurrences, and the display color corresponding to this upgraded failure level To be stored in the storage unit 4. As a result, even if the failure of the outdoor unit 12 or the indoor unit 10 is minor, the importance of the failure can be easily grasped visually based on the number of occurrences when the same failure occurs, and the operator can deal with the failure. Can be improved.

  Further, when the controller 3 receives a plurality of failure state data transmitted from the failed outdoor unit 12 or the indoor unit 10, the failure state display format is a scroll display or a flashing display depending on the importance of the failure state data. Is set to run. This failure display format is a format for executing scroll display or flushing display of a plurality of received failure state data in order of failure level at a constant cycle. Thereby, about the some outdoor unit 12 and the some indoor unit 10, the grade of each failure can be grasped | ascertained easily visually, and the serviceability of an operator's failure response can be improved.

  FIG. 10 shows an example of the loop display order when the failure states of the plurality of outdoor units 12 and the plurality of indoor units 10 are scroll-displayed or flushed in the failure display area of each management screen shown in FIGS. In the control unit 3, the failure state data received from the failed outdoor unit 12 or the indoor unit 10 is displayed in a loop in the order of the failure level from the severity level to the severity level. At this time, when the outdoor unit 12 and the indoor unit 10 have the same failure level, the failure state data of the outdoor unit 12 is displayed with priority over the failure state data of the indoor unit 10. For example, in FIG. The failure level of the compressor abnormality of the outdoor unit 12 of level 21 is level 5, indoor unit no. 03, the failure level of the outdoor unit communication abnormality of the indoor unit 10 is a failure level equivalent to level 5. The compressor abnormalities of the 21 outdoor units 12 are displayed with priority. Thereby, outdoor unit No. Since the failure state of the outdoor unit 12 of 21 can be grasped preferentially, the outdoor unit No. The plurality of indoor units 100 of group 1 and group 2 connected to the 21 outdoor units 12 can be quickly dealt with.

  FIG. 11 shows an example of loop display control when scrolling display or flushing display of failure states of the plurality of outdoor units 12 and the plurality of indoor units 10 is performed in the failure display area of each management screen shown in FIGS. In the control unit 3, the failure state data received from the failed outdoor unit 12 or the indoor unit 10 becomes the failure state data of the failure level in which the failure level is severe to mild and the failure level is severe. The failure state data is displayed so as to extend the display time. For example, in FIG. 11, the failure time data of each failure level from level 5 to level 1 has the longest display time of failure state data of the failure level of level 5, and the display time of failure state data of the failure level of level 1 The loop display is controlled so that is shortest. As a result, it is possible to make it easier to grasp the failure state of the failure level having a severe failure level without the operator being particularly conscious.
