<Operation of Air Conditioning Management System According to One Embodiment>
Next, the operation of the air conditioning management system 1 according to the present embodiment will be described. In the present embodiment, the display screen information generation unit 25 of the air-conditioning management apparatus 20 holds information on a floor configuration diagram showing the arrangement of a plurality of areas that constitute a floor regarding the first floor and the second floor of the building X to be managed. Has been. An example of the floor configuration diagram information held in the display screen information generation unit 25 will be described with reference to FIG.

  FIG. 2 is a screen configuration diagram when the floor configuration diagram information of the first floor of the building X held in the display screen information generation unit 25 is displayed on the screen. As shown in FIG. 2, the first floor has 21 areas 101, 102, 103, 111, 112... 172 divided in three or four directions by walls, doors, etc. Each area is provided with one or a plurality of air conditioners, as indicated by circles. For example, two air conditioners 101-1 and 101-2 are installed in the area 101, and three air conditioners 102-1, 102-2, and 102-3 are installed in the area 102. Here, in order to make it easy to understand the code of the air conditioner, the area number is described in the first half of the code (the front part of-), and the air conditioners in the same area are shown in the second half of the code.

  Calculation of area-specific data that is executed at predetermined time intervals (for example, intervals of several tens of seconds to several minutes) in the air conditioning management device 20 with the floor configuration diagram information including FIG. 2 held in the display screen information generation unit 25 The processing will be described with reference to the flowchart of FIG.

  In the air conditioning management device 20, when the execution timing of the area-specific data calculation process arrives ("YES" in S1), the air conditioner data acquisition unit 21 receives all air conditioners including the stopped air conditioners from The latest suction temperature data is acquired. The acquired suction temperature data is stored in the data storage unit 22 as room temperature data of each air conditioner (S2).

  An example of data stored in the data storage unit 22 is shown in FIG. In the example of FIG. 4, the room temperature data of the air conditioner 101-1 in the area 101 is calculated and stored as 31 ° C., the room temperature data of the air conditioner 101-2 is 29 ° C., and so on.

  Next, in the area-specific data calculation unit 23, the average room temperature value of the entire floor is calculated for each floor based on the room temperature data of each air conditioner stored in the data storage unit 22 and stored in the data storage unit 22. (S3). For example, as shown in FIG. 4, the average room temperature value of the first floor is calculated as 26 ° C. and stored.

  Next, the area-specific data calculation unit 23 calculates the average room temperature value of each area based on the room temperature data of each air conditioner stored in the data storage unit 22. Then, for each area, a difference value between the average room temperature value of the corresponding area and the average room temperature value of the entire floor stored in step S3 is calculated and stored in the data storage unit 22 (S4). For example, as shown in FIG. 4, the average room temperature value of the area 101 is stored as 30 ° C., the average room temperature value of the area 122 is stored as 24 ° C., and the average room temperature value of the area 125 is stored as 22 ° C. Furthermore, the difference value between the average room temperature value of the area 101 and the average room temperature value of the entire 1F floor is calculated as + 4 ° C., and the difference value between the average room temperature value of the area 122 and the average room temperature of the entire 1F floor is −2 ° C. The difference value between the average room temperature value of the area 125 and the average room temperature value of the entire 1F floor is calculated as −4 ° C., and these average room temperature values are stored in the data storage unit 22.

  Next, in the air conditioner data acquisition unit 21, data indicating the current capacity requirement ratio to the outdoor unit is acquired from all the connected air conditioners and stored in the data storage unit 22 (S5). For example, as shown in FIG. 4, the capacity requirement ratio 100% of the air conditioner 101-1 in the area 101, the capacity requirement ratio 90% of the air conditioner 101-2, etc. are acquired and stored. The air conditioner data acquisition unit 21 stores in advance the maximum capacity value of each air conditioner when connected to the air conditioning management device 20, and receives the requested capacity value at that time from each air conditioner during operation. Thus, the capacity requirement ratio of each air conditioner may be calculated in the air conditioner data acquisition unit 21.

  Next, the area-specific data calculation unit 23 calculates the average value of the capacity requirement ratios of the air conditioners in each area based on the capacity requirement ratio data of each air conditioner stored in the data storage unit 22. It is stored in the storage unit 22 (S6). For example, as shown in FIG. 4, the average capacity requirement ratio of area 101 is calculated as 95%, the average capacity requirement ratio of area 122 is 20%, the average capacity requirement ratio of area 125 is 0%, and the average of these is calculated. The capability request ratio is stored in the data storage unit 22.

  Next, in the air conditioner data acquisition unit 21, information on the current operation / stop state is acquired from all connected air conditioners (S7). And the integrated value of the operation time for every hour is calculated including the information of the operation / stop state of each acquired latest air conditioner (S8). For example, the operation time of the air conditioner 101-1 is calculated as 0 minutes at time 0 to 1, 10 minutes at 1 to 2 hours, 60 minutes at 2 to 3. However, it is calculated as follows: 0 minutes at time 0-1 o'clock, 30 minutes at 1-2 o'clock, 20 minutes at 2-3 o'clock.

  Next, based on the calculated integrated value of operating hours every hour, the total operating time of each air conditioner within the past 24 hours from the current time is calculated and stored in the data storage unit 22 (S9). . For example, as shown in FIG. 4, the total operation time of the air conditioners 101-1 and 101-2 in the area 101 is calculated as 480 minutes, the total operation time of the air conditioners 122-1 in the area 122 is calculated as 320 minutes, and so on. And memorized.

  Next, in the air conditioner data acquisition unit 21, information on the current thermo ON / OFF state is acquired from all the connected air conditioners (S10). The thermo-ON means that the air conditioner performs an air-conditioning operation with some capability, and the thermo-OFF means, for example, that the room temperature reaches the target temperature. This means that it is not necessary to perform air conditioning operation any more. Specifically, Thermo ON is distinguished when the required capacity value of the air conditioner is 0 or more, and Thermo OFF is distinguished when the required capacity value is 0. The Both the thermo ON and OFF indicate the state when the air conditioner operation instruction (air conditioner ON) has been issued, and the air conditioner stop instruction (air conditioner OFF) is excluded. Become.

  Then, an integrated value of the thermo OFF time for each hour is calculated including the acquired latest thermo ON / OFF state information (S11). For example, the thermo-off time of the air conditioner 101-1 is calculated as 0 minutes at 0 to 1 o'clock, 0 minutes at 1 to 2 o'clock, 55 minutes at 2 to 3 o'clock, and so on. The OFF time is calculated as 0 minute at 0 to 1 o'clock, 30 minutes at 1 to 2 o'clock, 20 minutes at 2 to 3 o'clock.

  Next, based on the calculated integrated value of the thermo OFF time for every hour, the total of the thermo OFF time of each air conditioner within the past 24 hours from the current time is calculated and stored in the data storage unit 22 ( S12). For example, as shown in FIG. 4, the thermo OFF time of the air conditioner 101-1 in the area 101 is 30 minutes, the thermo OFF time of the air conditioner 101-2 is 40 minutes, and the thermo OFF time of the air conditioner 122-1 in the area 122 is. It is calculated as 315 minutes and stored.

  Next, in the area-specific data calculation unit 23, based on the data stored in the data storage unit 22, the ratio of the thermo-OFF time within the past 24 hours of each air conditioner is set (within the past 24 hours of each air conditioner). ) (Total sum of operation times within the past 24 hours of each air conditioner) and stored in the data storage unit 22 (S13). For example, as shown in FIG. 4, the thermo OFF time ratio of the air conditioner 101-1 is 6%, the thermo OFF time ratio of the air conditioner 101-2 is 8%, and the thermo OFF time ratio of the air conditioner 122-1 is 98%.・ ・ Calculated and stored.

  Next, in the area-specific data calculation unit 23, based on the data stored in the data storage unit 22, the average value of the thermo-OFF time ratio of the air conditioners in each area is calculated and stored in the data storage unit 22. (S14). For example, as shown in FIG. 4, the average thermo OFF time ratio of the area 101 is stored as 7%, the average thermo OFF time ratio of the area 122 is stored as 95%.

  When these data are calculated and stored, the process returns to step S1, and when the next area-specific data calculation processing execution timing comes, the processing of steps S2 to S14 is repeated.

  When the administrator operates the input unit 24 in a state where various types of data are stored in the data storage unit 22 by the above-described processing, the floor to be displayed and the display mode are specified, the display screen information generation unit 25 Thus, display screen information for displaying the floor configuration diagram of the designated floor in the designated display mode is generated.

  Here, the display mode includes a temperature distribution display mode in which each area is displayed in a different color tone for each room temperature level, an air conditioning load distribution mode in which each area is displayed in a different color tone for each air conditioning load level, or a thermo OFF time. Any one of the thermo OFF time status display modes that indicate a long area in a predetermined color tone can be designated.

  The area-specific display color determination process executed by the display screen information generation unit 25 when the floor to be displayed and the display mode are designated by the operation of the administrator will be described with reference to the flowchart of FIG. The process shown in FIG. 5 is executed for all areas in the designated floor.

  When processing for the target area is started and it is determined that the designated display mode is the temperature distribution display mode (“YES” in S21), the average room temperature value and floor of the area stored in the data storage unit 22 are determined. If the difference value from the overall average room temperature value is a value lower than −3 ° C. (S22), it is determined to display the area portion in light blue (S23). If the difference between the average room temperature value of the area and the average room temperature of the entire floor is a value of −3 ° C. or more and less than 3 ° C. (“YES” in S24), the area portion is painted in white and displayed. Is determined (S25). Further, if the difference between the average room temperature value of the area and the average room temperature value of the entire floor is a value of 3 ° C. or more, it is determined that the area portion is painted in orange (S26).

  When it is determined that the designated display mode is the air conditioning load distribution mode (“NO” in S21, “YES” in S27), the average capacity requirement ratio of the area stored in the data storage unit 22 is 0. If it is greater than or equal to% and less than 30% (“YES” in S28), it is determined to display the area portion in light blue (S29). If the average capability requirement ratio of the area is 30% or more and less than 60% (“YES” in S30), it is determined that the area portion is displayed in white (S31). If the average capacity requirement ratio of the area is 60% or more, it is determined that the area portion is displayed in orange (S32).

  Further, when it is determined that the designated display mode is the thermo OFF time status display mode (“NO” in S21, “NO” in S27, “YES” in S33), the corresponding data stored in the data storage unit 22 is stored. If the area thermo-off time ratio is 0% or more and less than 95% (“YES” in S34), it is determined that the area portion is painted in white (S35). If the thermo OFF time ratio of the area is 95% or more, it is determined to display the area portion with a color tone that is emphasized, for example, gray (S36).

  The processes in steps S21 to S36 described above are executed for all areas in the designated floor, and the display color of each area in the designated display mode is determined. The display screen information generating unit 25 uses the configuration information of the designated floor, and the display screen information is generated so as to display each area in the determined display color, and is displayed on the display unit 26. .
