[0010] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1

[0011] 1 is a diagram showing the configuration of an air conditioning system according to embodiment 1. The air conditioning system includes a monitoring center 1, a plurality of air conditioners 2, and a mobile terminal 10.

[0012] The air conditioner 2 performs cooling, heating, or ventilation for the air-conditioned areas R1, R2, R3, etc. in which it is located. The air conditioner 2 is equipped with an air supply temperature sensor 3 and a communication device 4. The air supply temperature sensor 3 detects the temperature of the air at the air supply port of the air conditioner 2. The communication device 4 is configured to be capable of short-range wireless communication with the mobile terminal 10 via Bluetooth (registered trademark) or Wi-Fi. The communication device 4 is configured to be capable of communication with the monitoring center 1.

[0013] The mobile terminal 10 is held by a worker in the air-conditioned area of ​​the air conditioner 2. The mobile terminal 10 is configured to be capable of short-range wireless communication with the communication device 4 of the air conditioner 2.

[0014] 2 is a diagram showing the configuration of the monitoring center 1. The monitoring center 1 includes a memory 11, a processor 12, and a communication circuit 13.

[0015] The communication circuit 13 is configured to be able to communicate with the communication device 4 of the air conditioner 2. The memory 11 stores various data, programs, etc. The processor 12 executes the programs stored in the memory 11. The processor 12 calculates the PMV of the air-conditioned area of ​​the air conditioner 2 at a certain time, detects the presence of a worker in the air-conditioned area of ​​the air conditioner 2 at a certain time based on radio waves received by the communication device 4, and evaluates the comfort of the air-conditioned area of ​​the air conditioner 2 based on the PMV at multiple times and the detection results of the worker presence. The processor 12 evaluates the comfort of the air-conditioned area by excluding the PMV for times when the presence of a worker was not detected. FIG. 3 is a flowchart showing the procedure for evaluating the comfort of the air conditioner according to the first embodiment.

[0016] In step S101, if the current time point reaches a predetermined detection time point at every fixed time, the process proceeds to step S102.

[0017] In step S102, the processor 12 of the monitoring center 1 calculates the PMV of the air-conditioned area of ​​the air conditioner 2. For example, the processor 12 calculates the PMV of the air-conditioned area based on the air supply temperature of the air conditioner 2 detected by the air supply temperature sensor 3 and other factors. The other factors may use measured values ​​or may use predetermined values ​​determined by the current date and time.

[0018] In step S103, the processor 12 of the monitoring center 1 detects whether a worker is present in the air-conditioned area of ​​the air conditioner 2 based on whether radio waves are received from the mobile terminal 10 by the communication device 4 or whether the radio wave reception level is above a threshold.

[0019] In step S104, the processor 12 of the monitoring center 1 updates the detection table using the PMV calculated in step S102 and the presence of a worker in the air-conditioned area detected in step S103. Figure 4 is a diagram showing an example of the detection table of the first embodiment. The detection table records the PMV at the time of detection (date, time) and the presence or absence of a worker.

[0020] In step S105, if the current time point reaches a predetermined aggregation point for each fixed time period, the process proceeds to step S106.

[0021] In step S106, the processor 12 of the monitoring center 1 performs a counting process on the detection table. Fig. 5 is a diagram showing an example of the counting process in the first embodiment. For each period, the processor 12 of the monitoring center 1 calculates the average value of the PMW at the detection time when a worker is present in the air-conditioned area as the statistical value of the comfort index for that period. In Fig. 4, the PMVs at the detection times when no worker was present (PMV at April 1, 2023, 8:00:00, and April 1, 2023, 11:00:00) are not used in calculating the statistical value of the comfort index.

[0022] As described above, according to this embodiment, the PMV at times when the worker who is the user of the air conditioner is not present in the air-conditioned area is not used for comfort evaluation, so the comfort of the air conditioner user can be evaluated in accordance with the actual situation. Embodiment 2

[0023] In this embodiment, the processor 12 of the monitoring center 1 weights the PMV according to the number of detected workers.

[0024] Figure 6 is a flowchart showing the procedure for evaluating the comfort of an air conditioner in embodiment 2. The flowchart in Figure 6 differs from the flowchart in embodiment 1 in Figure 3 in that it includes steps S203, S204, and S206 instead of steps S103, S104, and S106, and further includes step S2031.

[0025] In step S203, the processor 12 of the monitoring center 1 detects the number of workers present in the air-conditioned area based on whether or not the communication device 4 receives radio waves from the mobile terminal 10, or whether or not the radio wave reception level is above a threshold.

[0026] In step S2031, the processor of the monitoring center 1 calculates a weighted PMV by weighting the PMV by the number of workers.

[0027] In step S204, the processor 12 of the monitoring center 1 updates the detection table using the weighted PMV. FIG. 7 is a diagram showing an example of a detection table according to the second embodiment. The detection table records the PMV at the time of detection (date, time), the number of workers, and the weighted PMV. The weighted PMV is expressed as the product of the number of workers and the PMV. Alternatively, the weighted PMV may be expressed as the product of the PMV and the output value of a function such as a logarithmic function that takes the number of workers as input.

[0028] In step S206, the processor 12 of the monitoring center 1 performs a counting process on the detection table. Fig. 8 is a diagram showing an example of the counting process in embodiment 2. The processor 12 of the monitoring center 1 calculates the average value of the weighted PMW for each period as a statistical value of the comfort index for that period.

[0029] As described above, according to this embodiment, the PMV is weighted according to the number of workers present in the air-conditioned area, so that the comfort of the air-conditioner users can be evaluated in accordance with the actual situation. Embodiment 3

[0035] In step S304, processor 12 of monitoring center 1 updates the detection table using the weighted PMV. Fig. 11 shows an example of a detection table according to the third embodiment. The detection table records the PMV at the time of detection (date, time), the number of customers, and the weighted PMV. The weighted PMV is expressed as the product of the number of customers and the PMV.

[0036] In step S306, the processor 12 of the monitoring center 1 executes the aggregation process of the detection table. For each period, the processor 12 of the monitoring center 1 calculates the average value of the weighted PMW as the statistical value of the comfort index for that period.

[0043] In step S4033, the processor 12 of the monitoring center 1 calculates a weighted PMV by weighting the PMV by the number of people in the air-conditioned area.

[0044] In step S404, the processor 12 of the monitoring center 1 updates the detection table using the weighted PMV.

The detection table records the PMV at the time of detection (date, time), the number of workers, the number of customers, the number of people (the sum of the number of workers and the number of customers), and the weighted PMV. The weighted PMV is expressed as the product of the number of people and the PMV.

[0045] In step S206, the processor 12 of the monitoring center 1 executes the aggregation process of the detection table. For each period, the processor 12 of the monitoring center 1 calculates the average value of the weighted PMW as the statistical value of the comfort index for that period.

[0046] As described above, according to this embodiment, the PMV is weighted by the sum of the number of workers and the number of customers in the air-conditioned area (= number of people), so the comfort of the air-conditioner users can be evaluated in accordance with the actual situation.

[0047] 14 is a diagram showing the configuration of an air conditioning system according to embodiment 5. An air conditioner 2 according to embodiment 5 is provided with a human presence sensor 5. The human presence sensor 5 is configured by, for example, an infrared sensor.

[0048] In this embodiment, the processor 12 of the monitoring center 1 weights the PMV by the number of customers present in the air-conditioned area, which is obtained by subtracting the number of workers present in the air-conditioned area from the number of people present in the air-conditioned area.

[0049] Fig. 15 is a flowchart showing the procedure for evaluating the comfort of an air conditioner according to embodiment 5. The flowchart in Fig. 15 differs from the flowchart in Fig. 3 according to embodiment 1 in that steps S503, S504, and S206 are provided instead of steps S103, S104, and S106, and steps S5031 and S5032 are further provided.

[0050] In step S502, the processor 12 of the monitoring center 1 detects the number of people in the air-conditioned area based on the detection result of the human presence sensor 5 of the air conditioner 2.

[0051] In step S503, the processor 12 of the monitoring center 1 detects the number of workers present in the air-conditioned area based on whether or not the communication device 4 receives radio waves from the mobile terminal 10, or whether or not the radio wave reception level is above a threshold.

[0052] In step S5031, the processor 12 of the monitoring center 1 calculates the number of customers in the air-conditioned area by subtracting the number of workers in the air-conditioned area detected in step S503 from the number of people in the air-conditioned area detected in step S502.

[0053] In step S5032, the processor 12 of the monitoring center 1 calculates a weighted PMV by weighting the PMV by the number of customers in the air-conditioned area.

[0054] In step S504, the processor 12 of the monitoring center 1 updates the detection table using the weighted PMV. Fig. 16 is a diagram showing an example of a detection table according to the fifth embodiment. The detection table records the PMV at the time of detection (date, time), the number of people, the number of workers, the number of customers, and the weighted PMV. The weighted PMV is expressed as the product of the number of customers and the PMV.

[0055] In step S206, the processor 12 of the monitoring center 1 executes the aggregation process of the detection table. For each period, the processor 12 of the monitoring center 1 calculates the average value of the weighted PMW as the statistical value of the comfort index for that period.
