[0054] (1) Overview of air conditioning control system

[0055] The air conditioning control system 100 of this embodiment is a system provided for performing air conditioning control of a room as a target space 80. Figure 1 As shown, the air conditioning control system 100 includes an air conditioner A and a sensor arrangement determination device 10 .

[0056] The air conditioning control system 100 of the present embodiment corresponds to the sensor arrangement determination device 10. The sensor arrangement determination device 10 is a device for implementing the sensor arrangement candidate determination method described in the claims.

[0057] The sensor arrangement determination device 10 communicates with equipment related to air conditioning of the target space 80 via the network 90. ​​In the present embodiment, the equipment related to air conditioning of the target space 80 is the air conditioner A. The air conditioner A is an indoor unit (indoor unit) of an air conditioner installed in the space.

[0058] The sensor arrangement determination device 10 determines the candidates for arrangement of sensors in the target space 80. The sensors include a normal sensor S1 and a training data acquisition sensor S2.

[0059] (2) Structure of air conditioning control system

[0060] (2-1) Sensor configuration determination device

[0061] The sensor configuration determining device 10 is implemented by a computer. Figure 1 As shown, the sensor configuration determination device 10 includes an acquisition unit 20 and a determination unit 30. The computer 10 includes a control operation device and a storage device. The control operation device can use a processor such as a CPU or a GPU. The control operation device reads out a program stored in the storage device and performs a predetermined image processing and operation processing according to the program. Furthermore, the control operation device can write the operation result to the storage device according to the program, or read out the information stored in the storage device. Figure 1 The acquisition unit 20 and the determination unit 30 shown are various functional blocks realized by the control operation device. These functional blocks are generated when the control operation device executes the program.

[0062] (2-1-1) Acquisition

[0063] The acquisition unit 20 acquires air conditioner information (first information) 21, which is information that associates factors that affect the environment in the target space 80 with the influence of the distance from the factors on the environment in the target space 80. In the present embodiment, the environment in the target space 80 is temperature. In addition, in the present embodiment, the factor that affects the temperature is the air conditioner (indoor unit) A.

[0064] like Figure 2 As shown, the air-conditioning control system 100 according to the present embodiment includes a plurality of air conditioners A1 to A4 in a target space 80 .

[0065] like Figure 3 As shown, the plurality of air conditioners A1 to A4 are provided with four outlets A1a to A4d along four sides, respectively. The air conditioners A1 to A4 have dampers 61a to 64d for adjusting the direction of air blown out from the outlets A1a to A4d.

[0066] In the present embodiment, the air conditioner information 21 is information that associates the air conditioner A with the influence of the distance from the air conditioner A. When the distance from the air conditioner A is small, the influence of the air conditioner A on the temperature in the target space 80 becomes larger. For example, when the straight-line distance from the air conditioner A is about 3 m or less, the influence of the air conditioner A on the temperature in the target space 80 becomes larger, but the straight-line distance from the air conditioner A is not limited to this.

[0067] The air conditioner information 21 includes: information about the impact on the temperature corresponding to the distance from the air conditioner A, which is determined based on any item in the model of air conditioner A, the shape of the indoor unit (air conditioner) A, the capacity of air conditioner A, the volume of conditioned air supplied by air conditioner A and the refrigerant system information (system information) of air conditioner A, and at least one of the combinations.

[0068] The models of the air conditioner A include indoor air conditioners for residences, air conditioners for shops or offices, multi-split air conditioners for buildings, etc. In addition, the shapes of the indoor unit (air conditioner) A include ceiling embedded box type, ceiling hanging type, floor-standing type, etc. In the present embodiment, the shape of the indoor unit A is a ceiling embedded box type.

[0069] When the capacity of air conditioner A is large, the influence of air conditioner A on the temperature in target space 80 becomes large. For example, when the capacity of air conditioner A is about 2.8 kW or more, the influence of air conditioner A on the temperature in target space 80 becomes large, but the capacity of air conditioner A is not limited to this.

[0070] When the air volume of the conditioned air supplied by the air conditioner A is large, the influence of the air conditioner A on the temperature in the target space 80 becomes large. For example, when the air volume of the conditioned air supplied by the air conditioner A is about 300 m 3When the air flow rate is greater than / min, the influence of the air conditioner A on the temperature in the target space 80 becomes greater, but the air volume of the conditioned air supplied by the air conditioner A is not limited to this.

[0071] The refrigerant system information of air conditioner A is information related to the connection between the indoor unit and the outdoor unit. Multiple indoor units connected to one outdoor unit through refrigerant piping belong to the same refrigerant system. For example, the first refrigerant system is formed by connecting multiple indoor units A1 to A4 to the first outdoor unit through refrigerant piping, and the second refrigerant system is formed by connecting multiple indoor units A5 to A8 (see Fig.12 ) is connected to the second outdoor unit.

[0072] The refrigerant system information of the air conditioner A includes information on which system the indoor units in the plurality of refrigerant systems belong to. For example, the refrigerant system information of the air conditioner A includes information that the indoor units A1 to A4 belong to the first refrigerant system.

[0073] In addition, the air conditioner information 21 may also include: information about the impact on temperature corresponding to the distance from air conditioner A, which is determined based on any item or combination of the wind direction, blowing temperature, blowing range and wind speed of the conditioned air supplied by air conditioner A.

[0074] like Figure 2 , Figure 3 As shown, each damper 61a-64d of the air conditioner (indoor unit) A1-A4 is provided at a position corresponding to each outlet A1a-A4d on the inner side of the outer peripheral sides of the lower surface of one indoor unit A1-A4 in a manner extending parallel to each side. The control unit (not shown) controls by changing the angle of each damper 61a-64d of each indoor unit A relative to each outlet A1a-A4d, so that the blown airflow can be directed to a predetermined position in the target space 80.

[0075] Fans (not shown) are provided in the indoor units A1 to A4 , respectively, and the speeds of the air flows blown out from the air outlets A1 a to A4 d are adjusted by a control unit.

[0076] In the direction in which the air-conditioned air supplied by the air-conditioner A blows, the air-conditioner A has a greater influence on the temperature in the target space 80. In the present embodiment, the air-conditioners A1 to A4 blow out the air-conditioned air from four directions of the outlets A1a to A4d. The air-conditioners A1 to A4 may also blow out the air-conditioned air from, for example, any two directions of the outlets A1a to A4d. In the direction in which the air-conditioned air is blown out from the outlets A1a to A4d of the air-conditioners A1 to A4, the air-conditioner A has a greater influence on the temperature in the target space 80.

[0077] In addition, when the temperature difference between the air outlet temperature of the air conditioner A and the indoor temperature of the target space 80 is large, the air outlet temperature of the air conditioner A has a greater influence on the temperature in the target space 80. For example, when the temperature difference between the air outlet temperature of the air conditioner A and the indoor temperature of the target space 80 is about 10° C. or more, the air outlet temperature of the air conditioner A has a greater influence on the temperature in the target space 80, but the temperature difference between the air outlet temperature of the air conditioner A and the indoor temperature of the target space 80 is not limited to this.

[0078] In addition, the air conditioner A has a greater influence on the temperature in the target space 80 within the blowing range of the indoor unit A. In the present embodiment, the indoor units A1 to A4 can operate by changing the blowing range of the indoor units A within a range of 30 to 90 degrees as viewed from the ceiling by changing the orientation of the dampers 61a to 64d.

[0079] When the wind speed of the indoor unit A is high, the influence of the air conditioner A on the temperature in the target space 80 becomes larger. For example, when the wind speed of the indoor unit A is about 1 m / s or more at a distance of 0 m from the air outlets A1a to A4d of the air conditioner A, the influence of the air conditioner A on the temperature in the target space 80 becomes larger, but the wind speed of the indoor unit A is not limited to this.

[0080] In addition, the acquisition unit 20 acquires spatial information (second information) 22 which is information related to the configuration of factors affecting the environment in the target space 80. In the present embodiment, the spatial information 22 is information related to the configuration of the air conditioner A in the target space 80. In addition, the spatial information 22 includes information related to the design model 70 of the building including the target space 80. In the present embodiment, the acquisition unit 20 acquires information related to the configuration of the air conditioner A in the target space 80 of the building from the design model 70 of the building. The spatial information 22 is not limited to the design model 70 of the building, and may also include information related to at least one of the analytical model, architectural drawing, and instrumentation drawing of the building.

[0081] (2-1-2) Decision-making Department

[0082] The decision unit 30 decides a placement candidate 31 of the normal sensor S1 in the target space 80 and a placement candidate 32 of the training data acquisition sensor S2 in the target space 80 based on the air conditioner information 21 and the space information 22 .

[0083] In this embodiment, the decision unit 30 determines the configuration candidate 31 of the constant sensor S1 in the object space 80 and the configuration candidate 32 of the sensor S2 for acquiring training data in the object space 80 based on the air conditioner information 21 that associates the air conditioner A with the influence of the distance from the air conditioner A and the space information 22 related to the configuration of the air conditioner A in the object space 80.

[0084] In addition, the determination unit 30 calculates the floor area of ​​the target space 80 based on the spatial information 22, and determines the number 33 of the permanent sensors S1 to be arranged in the target space 80 based on the floor area of ​​the target space 80. The determination unit 30 may also determine the number 33 of the permanent sensors S1 by dividing the target space 80 into a plurality of areas with a predetermined floor area based on the shape and size of the target space 80, the number of air conditioners A, and the accuracy of the target temperature prediction, and installing a permanent sensor S1 in each area.

[0085] In this embodiment, the determination unit 30 calculates the floor area of ​​the target space 80 based on the design model 70, and determines the number 33 of the permanent sensors S1 to be arranged in the target space 80 based on the floor area of ​​the target space 80. The permanent sensors S1 preferably have a floor area of ​​100 m2. 2 Up to 150m 2 In this embodiment, the ground area of ​​the target space 80 is about 100m 2 Configure a permanent sensor S1. For example, in the target space 80, the floor area is 100m 2 In the case of , the determination unit 30 determines that the number 33 of the permanent sensors S1 arranged in the target space 80 is "1".

[0086] (3) Sensor

[0087] The sensor is an environmental sensor that measures the environment in the target space 80. The sensor includes a permanent sensor S1 that is always installed in the target space 80 and a training data acquisition sensor S2 that is installed in the target space 80 when acquiring training data.

[0088] The environment in the target space 80 includes temperature, humidity, carbon dioxide concentration, etc. The environmental sensor includes a temperature sensor, a carbon dioxide sensor, a humidity sensor, etc. In the present embodiment, the sensor is a temperature sensor.

[0089] (3-1) Constant sensor

[0090] The constant sensor S1 is a temperature sensor for acquiring data related to the temperature in the target space 80. In the present embodiment, the constant sensor S1 acquires data related to the temperature in the target space 80.

[0091] The permanent sensor S1 is always installed in the target space 80 before and during the actual application of the air-conditioning control by the air-conditioning control system 100 .

[0092] The constant sensor S1 is arranged at a position determined by the sensor arrangement determination device 10 of the air-conditioning control system 100. The constant sensor S1 is arranged at a location in the target space 80 where the air conditioner A has little influence on the temperature.

[0093] (3-2) Sensors for acquiring training data

[0094] The training data acquisition sensor S2 is a temperature sensor for acquiring training data related to the temperature in the target space 80. In the present embodiment, the training data acquisition sensor S2 acquires training data related to the temperature in the target space 80.

[0095] The machine learning device (not shown) learns the soft sensing prediction model using the training data. The machine learning device learns by associating the data value of the constant sensor S1, which is the explanatory variable of the soft sensing prediction model, with the training data value of the training data acquisition sensor S2, which is the target variable of the soft sensing prediction model. The soft sensing prediction model uses the data value of the constant sensor S1 as the explanatory variable and predicts the temperature of the location where the training data acquisition sensor S2 is installed.

[0096] Before the actual application of the air-conditioning control by the air-conditioning control system 100 , the training data acquisition sensor S2 is installed at a position (prediction position) where the temperature in the target space 80 is predicted using the soft sensing prediction model.

[0097] After the actual application of air conditioning control by the air conditioning control system 100 begins, the sensor S2 for acquiring training data is recovered, and the parameter (temperature) is predicted by the prepared soft sensor prediction model, which is applied to visualization of temperature distribution, air conditioning control, etc.

[0098] The training data acquisition sensor S2 is arranged at a position determined by the sensor arrangement determination device 10 of the air conditioning control system 100. The training data acquisition sensor S2 is arranged, for example, at a position near a disturbance factor that has a strong influence on the temperature in the target space 80. The disturbance factor that has a strong influence on the temperature in the target space 80 includes a ventilation device B, a window D (see Figure 8 ) etc. Alternatively, the training data acquisition sensors S2 are evenly arranged in the entire object space 80.

[0099] (4) Overall operation of the air conditioning control system

[0100] Figure 4 FIG. 1 is a flow chart showing the air conditioning control system 100. Figure 4 In the description, a case where the air conditioners A1 to A4 are arranged in the target space 80 is taken as an example.

[0101] In step S11, the acquisition unit 20 acquires the air conditioner information 21. In the present embodiment, the acquisition unit 20 acquires the air conditioner information 21 which is information associating the air conditioners A1 to A4 with the influence of the distance from the air conditioners A1 to A4.

[0102] like Figure 5As shown, for example, the distance from the center position o1 of the air conditioner A1 to the prescribed position P1 near the center of the object space 80 is d1. The distance from the center position o2 of the air conditioner A2 to the prescribed position P1 near the center of the object space 80 is d2. The distance from the center position o3 of the air conditioner A3 to the prescribed position P1 near the center of the object space 80 is d3. The distance from the center position o4 of the air conditioner A4 to the prescribed position P1 near the center of the object space 80 is d4.

[0103] In addition, for example, the distance from the center position o1 of the air conditioner A1 to the specified position P2 of the area 80c of the object space 80 is d5. The distance from the center position o2 of the air conditioner A2 to the specified position P2 of the area 80c of the object space 80 is d6. The distance from the center position o3 of the air conditioner A3 to the specified position P2 of the area 80c of the object space 80 is d7. The distance from the center position o4 of the air conditioner A4 to the specified position P2 of the area 80c of the object space 80 is d8.

[0104] The acquisition unit 20 acquires, for example, information associating the air conditioner A1 with a distance d1 from the center position o1 of the air conditioner A1 to a predetermined position P1 of the area 80a of the target space 80 as the air conditioner information 21. Thereafter, the process proceeds to step S12.

[0105] In step S12, the acquisition unit 20 acquires the space information 22. In the present embodiment, the second information 22, which is information on the arrangement of the air conditioners A1 to A4 in the target space 80 of the building, is acquired from the design drawing 70.

[0106] like Figure 5 As shown, the target space 80 includes areas 80a to 80d. Air conditioner A1 is arranged in area 80a of the target space 80. Air conditioner A2 is arranged in area 80b of the target space 80. Air conditioner A3 is arranged in area 80c of the target space 80. Air conditioner A4 is arranged in area 80d of the target space 80. Then, the process proceeds to step S13.

[0107] In step S13, the determination unit 30 determines the number 33 of permanent sensors S1 to be installed. In step S13, based on the air conditioner information 21 obtained in step S11 and the space information 22 obtained in step S12, the target space 80 is divided into predetermined areas, one permanent sensor S1 is installed in each area, and the number 33 of permanent sensors S1 to be installed is determined.

[0108] In the present embodiment, the determination unit 30 calculates the floor area of ​​the target space 80 based on the space information 22 acquired in step S12 , and determines the number 33 of the permanent sensors S1 arranged in the target space 80 based on the floor area of ​​the target space 80 .

[0109] like Figure 5 As shown, the floor area of ​​the target space 80 is 100m with side L being 10m and side M being 10m. 2 Therefore, the determination unit 30 determines the number 31 of installation of the permanent sensor S1 in the target space 80 to be "1". Then, the process proceeds to step S14.

[0110] In step S14, the determination unit 30 extracts the position where the normal sensor S1 is not properly arranged. In the present embodiment, the position where the normal sensor S1 is not properly arranged is the range where the airflow from the air conditioner A reaches.

[0111] The determination unit 30 estimates the maximum air volume of the air conditioner A and the reach of the blown air flow in each wind direction based on the shape of the air conditioner (indoor unit) A, the capacity of the air conditioner A, and the air volume of the air conditioner A, and extracts the reach of the blown air flow of the air conditioner A as the position where the sensor S1 is not normally arranged. In addition, the reach of the blown air flow of the air conditioner A can also be estimated based on the physical distance from the air conditioner A.

[0112] By associating the characteristics of the model of the indoor unit A with the reach of the airflow, the air conditioner information 21 is obtained, thereby obtaining the reach of the airflow of the air conditioner A in the target space 80. The reach of the airflow of the air conditioner A is a range of about 0 m to about 3 m from the outlet of the air conditioner A, but the reach of the airflow of the air conditioner A is not limited to this.

[0113] Figure 6 FIG. 1 is a diagram for explaining an example of an unsuitable location for setting the sensor S1. Figure 6 As shown, the reach range of the airflow blown out of the outlet A4a of the air conditioner A4 is, for example, a range where the distance R from the outlet A4a of the air conditioner A4 is 3 m and the angle between the direction f1 of 30 degrees between the air conditioner A4 and the ceiling of the target space 80 and the direction f2 of 90 degrees between the air conditioner A4 and the ceiling of the target space 80 is θ. Then, the process proceeds to step S15.

[0114] In step S15, the decision unit 30 decides on a configuration candidate 31 that is a recommended installation position (range) for the permanent sensor S1. In step S15, the position that is extracted in step S14 and is not suitable for the installation of the permanent sensor S1 is excluded from the object space 80. In the present embodiment, the reach of the airflow of the air conditioner A is excluded from the object space 80. In addition, the middle position of each air conditioner A belonging to the area divided in step S13 in the area after the reach of the airflow of the air conditioner A is excluded from the object space 80 is determined as the recommended installation position (range) for the permanent sensor S1. In the present embodiment, the middle position of each indoor unit A1 to A4 from the areas 80a to 80d set in the object space 80 is determined as the configuration candidate 31 for the permanent sensor S1 (refer to Figure 7 ). After that, go to step S16.

[0115] In step S16, the decision unit 30 decides the arrangement candidate 32 that is the recommended arrangement position (range) of the training data acquisition sensor S2. In step S16, the decision unit 30 extracts the positions 32a, 32b, 32c, and 32d (see FIG. 1 ) where the training data acquisition sensor S2 should be arranged based on the range of the position where the normal sensor S1 is not suitable for arrangement extracted in step S14. Figure 7 The positions 32a, 32b, 32c, and 32d where the training data acquisition sensor S2 is to be installed are the reachable ranges of the blown air flows of the air conditioners A1 to A4.

[0116] The decision unit 30 can also determine the positions where the air conditioners A1~A4 have a strong impact on the temperature based on the air conditioner information 21 obtained in step S11 and the space information 22 obtained in step S12 through threshold judgment, etc., as the positions 32a, 32b, 32c, and 32d where the training data acquisition sensor S2 should be set.

[0117] Then, the decision unit 30 obtains other multiple positions 32e, 32f (see FIG. 1 ) in a manner that the training data acquisition sensor S2 is evenly distributed in the object space 80. Figure 7 ).

[0118] The decision unit 30 decides positions 32 a , 32 b , 32 c , and 32 d where the training data acquiring sensor S2 should be installed and other positions 32 e and 32 f of the training data acquiring sensor S2 as the placement candidates 32 of the training data acquiring sensor S2 .

[0119] Figure 7 80 is a diagram for explaining an example of the installation range of sensors in the target space 80. One permanent sensor S1 and six training data acquisition sensors S2 (S2a to S2f) are arranged in the target space 80. Figure 7As shown, the target space 80 includes areas 80a to 80d. The air conditioner A1 is arranged in the area 80a of the target space 80. The air conditioner A2 is arranged in the area 80b of the target space 80. The air conditioner A3 is arranged in the area 80c of the target space 80. The air conditioner A4 is arranged in the area 80d of the target space 80.

[0120] The constant sensor S1 is arranged in the target space 80 at the middle position of the air conditioners A1 to A4, i.e., the arrangement candidate 31. The training data acquisition sensor S2a is arranged near the air conditioner A1, i.e., the arrangement candidate 32a. The training data acquisition sensor S2b is arranged near the air conditioner A2, i.e., the arrangement candidate 32b. The training data acquisition sensor S2c is arranged near the air conditioner A3, i.e., the arrangement candidate 32c. The training data acquisition sensor S2d is arranged near the air conditioner A4, i.e., the arrangement candidate 32d. The training data acquisition sensor S2e is arranged at a position where the airflow of the air conditioners A1 to A4 does not reach, i.e., the arrangement candidate 32e. The training data acquisition sensor S2f is arranged at a position where the airflow of the air conditioners A1 to A4 does not reach, i.e., the arrangement candidate 32f.

[0121] (5) Features

[0122] (5-1)

[0123] The sensor configuration determination device 10 of the present embodiment determines the configuration of the sensor for measuring the temperature in the target space 80, and the sensor configuration determination device 10 includes an acquisition unit 20 and a determination unit 30. The acquisition unit 20 acquires air conditioner information 21 and space information 22. The air conditioner information 21 is information that associates the air conditioner A that affects the temperature with the influence of the distance from the air conditioner A on the temperature. The space information 22 is information related to the configuration of the air conditioner A in the target space 80. The determination unit 30 determines the configuration candidate 31 of the permanent sensor S1 in the target space 80 and the configuration candidate 32 of the sensor S2 for acquiring training data based on the air conditioner information 21 and the space information 22.

[0124] In the previous air conditioning control system, the air conditioner was controlled using the values ​​of sensors installed in the indoor unit and remote controller. Therefore, since the temperature and airflow conditions in the living area (about 1.7m above the ground) were not taken into consideration, there were demands for air conditioning caused by uneven temperature and wind (wind force).

[0125] For example, in the actual temperature distribution of the air-conditioned space, the temperature changes differently depending on the location in the air-conditioned space, such as the location that the air flow of the air conditioner reaches or does not reach, the location with different heights in the air-conditioned space, the location with strong or weak interference effects, the location affected by indoor units of multiple refrigerant systems, etc. In the past, when using sensors installed in the space to control the air conditioner, local values ​​were obtained and reflected in the air-conditioning control. Therefore, when installing sensors at locations with singular points such as near heating equipment, crowded areas, shadows of partitions, and locations with strong sunlight effects, it may be impossible to build the target environment.

[0126] Furthermore, the location of environmental sensors in a space is important not only for controlling air conditioners but also for obtaining parameter distribution of a space for the purpose of visualizing parameter distribution in an air-conditioned space. Parameters in an air-conditioned space include, for example, temperature, humidity, CO 2 , airflow, comfort (PMV: predicted mean temperature report). By measuring the distribution of parameters in the living area of ​​the space, it is possible to perform air conditioning control and ventilation control that conforms to the actual way people feel, or visualize parameter distribution, and can assist in changing the settings of air conditioners, helping indoor occupants choose a comfortable place for themselves, and assisting in research on equipment introduction.

[0127] When the purpose is to visualize parameter distribution, the parameter distribution of the entire space cannot be accurately obtained without measuring not only the environment that occupies most of the space but also the parts that affect the parameters and various singular points generated in the space.

[0128] In addition, in the case of predicting parameter distribution, a permanent sensor that is always set in the space and a training data acquisition sensor that is recovered after the training data is acquired are required. The permanent sensor needs to be located at a position that is not a singular point. The training data acquisition sensor also needs to be set at a specified interval in the space, including the singular point.

[0129] However, service engineers who actually install sensors do not have such insights, and if there are no rules regarding the installation of sensors, it is difficult to install the sensors at the optimal positions in the space.

[0130] When using sensors to optimally control air conditioners as described above, or when outputting parameter distribution, etc., it is important to place sensors at optimal locations. However, in the prior art, it is not possible to find the optimal location for achieving the accuracy of temperature prediction as the target, nor is it known what the optimal number of sensors is. Therefore, the location and number of environmental sensors depend on the feelings of service engineers, and there are cases where accuracy cannot be ensured, and cases where unnecessary costs are incurred due to exceeding specifications.

[0131] In the sensor configuration determination device 10, the influence of the air conditioner A in the target space 80 on the temperature is considered to determine the configuration candidates 31 of the normal sensor S1 and the configuration candidates 32 of the training data acquisition sensor S2, thereby being able to predict the temperature in the target space 80 with high accuracy.

[0132] In addition, in the sensor arrangement determination device 10, the arrangement candidate 31 of the permanent sensor S1 and the arrangement candidate 32 of the training data acquisition sensor S2 that achieve the target temperature prediction accuracy can be determined, and the accuracy of air conditioning control and the accuracy of temperature distribution prediction can be improved. In addition, in the sensor arrangement determination device 10, the man-hours for studying the installation positions of the permanent sensor S1 and the training data acquisition sensor S2 can be reduced, and the permanent sensor S1 and the training data acquisition sensor S2 can be installed at the optimal position in the object space 80 without relying on the feeling of the service engineer. In addition, in the sensor arrangement determination device 10, by acquiring the air conditioner information 21 and the space information 22, the installation positions of the permanent sensor S1 and the training data acquisition sensor S2 can be studied even if they are not in the actual space. In addition, by determining the arrangement candidate 31 of the permanent sensor S1 and the arrangement candidate 32 of the training data acquisition sensor S2 by the sensor arrangement determination device 10, the temperature of other positions where the training data acquisition sensor S2 is not installed can be predicted, thereby suppressing the cost of the sensor.

[0133] (5-2)

[0134] In the sensor arrangement determination device 10 of the present embodiment, the space information 22 includes information on the design model 70 of the building.

[0135] The sensor arrangement determination device 10 can obtain information on the target space 80 from the building design model 70. Thus, the arrangement candidates 31 of the normal sensor S1 and the arrangement candidates 32 of the training data acquisition sensor S2 can be appropriately determined for each target space 80 where sensors are installed in the building.

[0136] (5-3)

[0137] In the sensor arrangement determination device 10 of the present embodiment, the factor affecting the temperature in the target space 80 is the air conditioner A. The air conditioner information 21 includes information on the influence on the temperature corresponding to the distance from the air conditioner A, determined based on at least one of any item or combination of the model of the air conditioner A, the shape of the air conditioner (indoor unit) A, the capacity of the air conditioner A, the air volume of the conditioned air supplied by the air conditioner A, and the system information of the air conditioner A.

[0138] In the sensor arrangement determination device 10, the arrangement candidate 31 of the permanent sensor S1 and the arrangement candidate 32 of the training data acquisition sensor S2 can be determined by taking into account the influence of the air conditioner A on the temperature in the target space 80. Thus, the arrangement candidate 31 of the permanent sensor S1 and the arrangement candidate 32 of the training data acquisition sensor S2 can be appropriately determined according to the air conditioner A installed in the target space 80.

[0139] (5-4)

[0140] In the sensor configuration determination device 10 of the present embodiment, the air conditioner information 21 also includes: information about the impact of the temperature corresponding to the distance from the air conditioner A, which is determined based on any item and at least one of the combinations of the wind direction, blowing temperature, blowing range and wind speed of the conditioned air provided by the air conditioner A.

[0141] In the sensor arrangement determination device 10 , the arrangement candidates 31 of the normal sensor S1 and the arrangement candidates 32 of the training data acquisition sensor S2 can be determined in consideration of the influence of the conditioned air supplied by the air conditioner A on the temperature in the target space 80 .

[0142] (5-5)

[0143] In the sensor arrangement determination device 10 of the present embodiment, the determination unit 30 calculates the floor area of ​​the target space 80 based on the space information 22 , and determines the number 33 of permanent sensors S1 arranged in the target space 80 based on the floor area of ​​the target space 80 .

[0144] In the sensor arrangement determination device 10, the number 33 of installation of the permanent sensors S1 is determined in consideration of the size of the target space 80, so that a large number of sensors are not arranged, and the cost can be reduced.

[0145] (5-6)

[0146] In the sensor configuration determination method using the sensor configuration determination device 10 of the present embodiment, the configuration of the sensor S for measuring the temperature in the target space 80 is determined, and the sensor configuration determination method includes an acquisition step and a determination step. The acquisition step acquires the air conditioner information 21 and the space information 22. The air conditioner information 21 is information that associates the air conditioner A with the influence of the distance from the air conditioner A. The space information 22 is information related to the configuration of the air conditioner A in the target space 80. The determination step determines the configuration candidate 31 of the permanent sensor S1 in the target space 80 and the configuration candidate 32 of the sensor S2 for acquiring training data based on the air conditioner information 21 and the space information 22.

[0147] In the sensor configuration determination method using the sensor configuration determination device 10, the influence of the air conditioner A on the temperature in the object space 80 is taken into consideration to determine the configuration candidate 31 of the normal sensor S1 and the configuration candidate 32 of the sensor S2 for obtaining training data, thereby enabling the temperature in the object space 80 to be predicted with high accuracy.

[0148] (6) Modification

[0149] (6-1) Modification 1A

[0150] In the sensor arrangement determination device 10 of the present embodiment, the case where the factor affecting the temperature in the target space 80 is the air conditioner A is described, but the present invention is not limited to this.

[0151] exist Figure 1 In the sensor configuration determination device 10 shown in FIG. 1 , the affected object space 82 (see Figure 8 ) can also be a factor of the temperature in the ventilation device B (refer to Figure 8 ). In addition, Figure 1 In the sensor arrangement determination device 10 shown, the factors affecting the temperature in the target space 82 may also be the air conditioner A and the ventilation device B.

[0152] When the factor affecting the temperature in the target space 82 is the ventilator B, the acquisition unit 20 acquires the ventilator information as the first information. The ventilator information includes information on the influence on the temperature corresponding to the distance from the ventilator B, which is determined based on at least one of any one of the following items and a combination: the model of the ventilator B, the shape of the ventilator B, the ventilation volume of the ventilator B, the air volume of the air supplied by the ventilator B, the presence or absence of a total heat exchanger, the heat exchange efficiency of the total heat exchanger, and the presence or absence of a temperature adjustment function of the ventilator B.

[0153] When the distance from the ventilator B is small, the influence of the ventilator B on the temperature in the target space 82 becomes larger, and the temperature change in the target space 82 caused by the ventilator B becomes larger. For example, when the distance from the ventilator B is about 3 m or less, the influence of the ventilator B on the temperature in the target space 82 becomes larger, but the distance from the ventilator B is not limited to this.

[0154] The models of the ventilation device B include ventilation fans, total heat exchangers, humidity-controlled external air handling units, etc. The shapes of the ventilation device B include propeller fans, sirocco fans, etc.

[0155] When the ventilation volume of the ventilator B is large, the influence of the ventilator B on the temperature in the target space 82 becomes large. For example, when the ventilation volume of the ventilator B is about 300 m 3When the ventilation rate is greater than 100 Hz / h, the influence of the ventilator B on the temperature in the target space 82 becomes greater, but the ventilation rate of the ventilator B is not limited to this.

[0156] When the air volume supplied by the ventilator B is large, the influence of the ventilator B on the temperature in the target space 82 becomes large. For example, when the air volume supplied by the ventilator B is about 300 m 3 When the flow rate is greater than 100 Hz / h, the influence of the ventilator B on the temperature in the target space 82 becomes greater, but the flow rate of the air supplied by the ventilator B is not limited to this.

[0157] When the ventilator B is a total heat exchanger, heat exchange is performed between the indoor air and the outdoor air, so the temperature of the air obtained from the outdoor and supplied to the indoor is close to the indoor air temperature. Therefore, the influence of the ventilator B on the temperature in the target space 82 becomes small. In addition, when the heat exchange efficiency of the total heat exchanger is high, the influence of the ventilator B on the temperature in the target space 82 becomes small.

[0158] In addition, when the ventilator B has a temperature adjustment function, the degree of influence of the ventilator B on the temperature in the target space 82 varies depending on the operation content of the temperature adjustment function of the ventilator B. In the case where the ventilator B with the temperature adjustment function is operated in a manner such that the supply air temperature approaches the indoor temperature, the influence of the ventilator B on the temperature in the target space 82 becomes smaller. In addition, when the ventilator B with the temperature adjustment function is operated in a manner such that the temperature-adjusted air is supplied to the target space 82 in the same manner as the air conditioner A, the influence of the ventilator B on the temperature in the target space 82 becomes larger.

[0159] Furthermore, by associating the characteristics of the ventilator B with the reach of the airflow blown out of the ventilator B and inputting the ventilator information into the sensor arrangement determination device 10, the influence range of the ventilator B on the temperature in the target space can be obtained.

[0160] In Modification 1A, the placement candidates 31 of the normal sensor S1 and the placement candidates 32 of the training data acquisition sensor S2 in the target space 82 can be determined in consideration of the influence of the air conditioner A and the ventilator B on the temperature in the target space 82 .

[0161] (6-2) Modification 1B

[0162] exist Figure 1 In the sensor configuration determination device 10 shown in FIG. 1 , the factor affecting the temperature in the target space 82 may also be daily necessities C (see FIG. Figure 8 ). Daily utensils are utensils and furniture used in daily life. Examples of daily utensils are partitions, shelves, etc.

[0163] When the factor affecting the temperature in the target space 82 is the daily appliance C, the acquisition unit 20 acquires the daily appliance information as the first information. The daily appliance information includes information on the influence on the temperature corresponding to the distance from the daily appliance C, which is determined according to the type of the daily appliance C. For example, when the daily appliance C arranged in the target space 82 is a partition, the airflow in the target space 82 changes near the partition, and thus the measurement value of the sensor is easily affected by the partition.

[0164] When the distance from the daily utensil C is small, the influence of the daily utensil C on the temperature in the target space 82 becomes larger, and the temperature change in the target space 82 caused by the daily utensil C becomes larger. For example, when the daily utensil C is a partition and the distance from the daily utensil C is about 0.1 m or less, the influence of the daily utensil C on the temperature in the target space 82 becomes larger, but the distance from the daily utensil C is not limited to this.

[0165] In addition, Figure 1 In the sensor arrangement determination device 10 shown, the factor affecting the temperature in the target space 82 may also be an everyday appliance (heat generating body) that generates heat. An example of an everyday appliance that generates heat is a personal computer F (see Figure 8 ), printers, etc.

[0166] For example, when the daily appliance associated with heat generation is a desktop computer and the distance to the desktop computer generating 100 W of heat is approximately 0.2 m or less, the desktop computer has a greater influence on the temperature in the target space 82 .

[0167] In the modification 1B, the arrangement candidates 31 of the normal sensor S1 and the arrangement candidates 32 of the training data acquisition sensor S2 can be determined in consideration of the influence of the daily tools C on the temperature in the target space 82 .

[0168] (6-3) Modification 1C

[0169] exist Figure 1 In the sensor configuration determination device 10 shown in FIG. 1 , the factor affecting the temperature in the target space 82 may be the window D (see FIG. 1 ) of the target space 82. Figure 8 ). When the factor affecting the temperature in the target space 82 is the window D, the acquisition unit 20 acquires the window information as the first information. The window information is the influence on the temperature corresponding to the distance from the window D, which is determined based on at least one of any item or combination of the size of the window D, the heat transfer coefficient, the sunlight acquisition coefficient, and the presence or absence of an obstruction.

[0170] When the distance from the window D is small, the influence of the window D on the temperature in the target space 82 becomes larger, and the temperature change in the target space 82 caused by the window D becomes larger. For example, when the distance from the window D is about 1.0 m or less, the influence of the window D on the temperature of the target space 82 becomes larger, but the distance from the window D is not limited to this.

[0171] The heat transfer coefficient is a value indicating the ease of heat transfer when heat transfer occurs through the window D. The heat transfer coefficient can be calculated using software. In addition, the heat transfer coefficient can be measured using a heat flow sensor. When the temperature difference between the outside and the inside of the window D of the target space 82 is large, the heat transfer coefficient becomes high.

[0172] The sunshine acquisition coefficient is the average ratio of the “actual sunshine amount that can be obtained inside the building” to the “sunlight amount that can be obtained if there is no building blocking the sunlight.” When the sunshine acquisition coefficient is large, the amount of heat from the sunshine is large.

[0173] The shielding object is a curtain, a blind, a door or a window, etc., which shields the sunlight from the window D. When the window D has a shielding object, the measurement value of the sensor is not easily affected by the window D.

[0174] Furthermore, when the window D is large, the measured value of the sensor in the vicinity of the window D is easily affected.

[0175] In the modification 1C, the arrangement candidate 31 of the normal sensor S1 and the arrangement candidate 32 of the training data acquisition sensor S2 can be determined in consideration of the influence of the window D on the temperature in the target space 82 .

[0176] (6-4) Modification 1D

[0177] exist Figure 1 In the sensor arrangement determination device 10 shown in FIG. 1 , the factor affecting the temperature in the target space 82 may also be the door E (see FIG. 1 ) of the target space 82. Figure 8 ). When the factor affecting the environment in the target space 82 is the door E, the acquisition unit 20 acquires the door information as the first information. The door information is the influence on the temperature corresponding to the distance from the door E, which is determined based on at least one of any item or combination of the size, heat insulation performance and opening and closing frequency of the door E.

[0178] When the distance from the door E is small, the door E has a greater influence on the temperature in the target space 82, and the temperature change in the target space 82 caused by the door E becomes larger. For example, when the distance from the door E is about 2 m or less, the door E has a greater influence on the temperature in the target space 82, but the distance from the door E is not limited to this.

[0179] When the door E is large, the measured value of the sensor near the door E is easily affected.

[0180] Furthermore, when the heat insulation performance of the door E is high, the heat input and output between the indoor and outdoor areas decreases, and the measurement value of the sensor in the target space 82 is less likely to be affected by the outside air temperature.

[0181] When the frequency of opening and closing of the door E is high, the heat flow between indoors and outdoors increases, and the measurement value of the sensor is easily affected.

[0182] In the modification 1D, the candidates for the placement candidate 31 of the normal sensor S1 and the placement candidate 32 of the training data acquisition sensor S2 can be determined in consideration of the influence of the door E on the temperature in the target space 82 .

[0183] (6-5) Modification 1E

[0184] exist Figure 1 In the sensor arrangement determination device 10 shown, the determination unit 30 may determine the number 33 of the permanent sensors S1 arranged in the target space 82 according to the number of factors that affect the temperature in the target space 82 .

[0185] Figure 8 82 is a diagram for explaining factors affecting the environment in the object space 82. Figure 8 As shown, the target space 82 includes air conditioners A1 to A4 (A3 and A4 are not shown), ventilators B1 and B2 (B2 is not shown), daily tools C, a window D, a door E, and a personal computer F.

[0186] As described in the present embodiment, the air conditioner A is a factor that affects the temperature in the target space 82. As described in Modifications 1A to 1D, the ventilator B, the daily appliance C, the window D, and the door E are factors that affect the temperature in the target space 82. In addition, as described in Modification 1B, the personal computer F is a heat source and is a factor that affects the temperature in the target space 82.

[0187] in addition, Figure 8 The outer skin load G shown is a heat load that enters the room from the outside through the outer skin of the target space 82 such as the ceiling, walls, and floor, and is a factor that affects the temperature in the target space 82.

[0188] The acquisition unit 20 acquires the spatial information 22 (architectural drawings, piping drawings, CAD models, BIM models, etc.) of the object space 82 where the normal sensor S1 and the training data acquisition sensor S2 are installed, the installation position of the air conditioner A (horizontal coordinates, height, etc. of the indoor unit), the installation position of the ventilation device B (horizontal coordinates, height), air conditioner information 21 (machine model, indoor unit shape, capacity, air volume, system information), ventilation device information (machine model, shape, air volume, presence or absence of a total heat exchanger, heat exchange efficiency of the total heat exchanger, presence or absence of a temperature control function), the position of daily appliances C such as partitions, the position of heat generating bodies such as personal computers F, the position of people, the heat transfer coefficient of window D, the heat transfer coefficient of door E, the heat transfer coefficient of the wall, and the sunlight acquisition coefficient of window D, etc.

[0189] The decision unit 30 uses the air conditioner information 21, the air conditioner controller information, the ventilation device information, the space information 22 of the object space 82, the installation position of the air conditioner A, the installation position of the ventilation device B, the position of daily appliances C such as partitions, the position of people, the heat transfer coefficient of the window D, the heat transfer coefficient of the door E, the heat transfer coefficient of the wall and the sunlight acquisition coefficient, etc., to calculate where in the object space 82 the environmental information (temperature information) required to "most efficiently control the space" and "accurately obtain real-time information of the entire space" should be obtained.

[0190] In modification 1E, the value 33 of the constant sensor S1 is determined in consideration of the number of factors affecting the temperature in the target space 82 , and the optimal value 33 of the constant sensor S1 can be determined regardless of the number of factors affecting the temperature in the target space 82 .

[0191] (6-6) Modification 1F

[0192] In the present embodiment, the case where the position where the sensor S1 is not properly arranged is the airflow arrival area of ​​the air conditioner A is described, but the present invention is not limited to this.

[0193] In order to efficiently control the air conditioners, what is needed is sensing at the location where the air is conditioned by each air conditioner.

[0194] However, for example, when the temperature detected by the environment sensor is used to control air conditioning, if the environment sensor is installed at a position directly receiving the airflow from the air conditioner, it is difficult to grasp the environment other than the position where the airflow reaches. In addition, when the environment sensor is installed near a heat-generating device such as a personal computer, the heat will also be detected by the environment sensor. In such a case, the control is only for a specific point, and it will not be the best control for the whole.

[0195] However, when these environmental sensors are installed based on the intuition and experience of service engineers, they may not be installed at the optimal positions, and even if they can be installed, more environmental sensors than necessary may be installed, which may increase costs.

[0196] In addition, when predicting environmental parameters, there are the same issues as when controlling air conditioners. As an example of an application method, a permanent sensor is always set in the environmental sensor, and the environmental sensor used for obtaining training data is recovered after obtaining training data. Consider a method of using the value of the permanent sensor as an explanatory variable to predict the temperature of the location where the environmental sensor used for obtaining training data is set in real time.

[0197] In this example, when the permanent sensor is installed at the singular point, the parameter of the permanent sensor as the explanatory variable may have redundant elements in predicting the parameter of the environmental sensor for obtaining training data, or may lack elements in prediction.

[0198] As the installation position of the permanent sensor, it is necessary to install it at a position that is not a singular point. In addition, in order to obtain the environment of the entire space, the environmental sensor used for obtaining training data needs to obtain training data at a position that is not a singular point and at a singular point.

[0199] Fig.9A and Fig. 9B It is a diagram for explaining another example of an inappropriate position of the sensor S1.

[0200] like Fig.9A As shown in FIG. 1 , the position where the sensor S1 is not normally configured is near a singular point. A singular point is a point where the environment (temperature) is locally different from the surroundings. Examples of singular points are a position 35a near a personal computer F that is a heat source in the target space 82, a position 35b that is strongly affected by sunlight from a window D, a position 35c that is a shadow of a daily appliance C when viewed from the outlet of an air conditioner A, and a position 35d that is a shadow of a door E (see FIG. 1 ). Figure 8 ), densely populated areas, etc.

[0201] Regarding the heat generating body, the distance that affects the temperature is stored in association with the type and the calorific value of the heat generating body, and the singular point in the target space 82 is derived from the spatial information 22 on the arrangement of the heat generating body in the target space 82 .

[0202] Regarding window D, the heat load at the peak is estimated based on the size of window D, the heat transfer coefficient, the sunshine acquisition coefficient, and the presence or absence of an obstruction. Based on the estimated heat load, the influence distance on the temperature is calculated to derive the singular point. At this time, windows that can be judged to have little influence on the temperature, such as windows on the side adjacent to other buildings that are almost not affected by sunshine, can also be excluded from the singular point.

[0203] In addition, regarding the door E, the influence distance on the temperature is calculated by inputting the size, heat transfer coefficient, and opening and closing frequency of the door E, and the singular point is derived. At this time, closed doors and other doors that can be judged to have little influence on the temperature can be excluded from the singular point.

[0204] In addition, if Fig. 9B As shown, the position where the sensor S1 is not suitable for placement is a non-installable position. The non-installable position refers to a position 35d in the target space 82 where the sensor cannot be physically installed, such as in the air, or on the ground 35e.

[0205] According to the spatial information 22, a range where the sensor cannot be physically installed in the air, a position not suitable for permanent installation, such as the ground, a position far from the residential area, such as the ceiling, etc. is obtained. In addition, the position (range) where the sensor S1 is not suitable for permanent installation can also be added with a setting prohibition range based on the user's input.

[0206] exist Figure 1 In the sensor configuration determination device 10, in each area divided by the ground area of ​​the object space 82 except for the position (range) where the permanent sensor S1 is not suitable for configuration, the recommended setting position or range of the permanent sensor S1 is determined in a manner close to the middle of the area.

[0207] Regarding the training data acquisition sensor S2, based on the position (range) where the normal sensor S1 is not properly arranged, the airflow arrival range and the singular point where the temperature needs to be measured are determined, and the installation position (range) of the training data acquisition sensor S2 is determined in such a way that the training data acquisition sensor S2 is spread over the entire object space 82 at a predetermined distance interval in the airflow arrival range and the range other than the singular point. The distance interval of the training data acquisition sensor S2 is determined based on the accuracy of the target temperature prediction.

[0208] In addition, the training data acquisition sensor S2 may be specified in the air, etc., which is excluded as a position (range) where the sensor S1 is not normally configured. In this case, the training data acquisition sensor S2 is configured using a member such as a pole or a tripod. When the training data acquisition sensor S2 is set in the air of the target space 82, the temperature distribution in the vertical direction of the target space 82 may be acquired.

[0209] In modification 1F, positions that may become singular points in the target spaces 80 and 82 are estimated based on the spatial information 22 acquired by the acquisition unit 20 and excluded from the placement candidates of the permanent sensor S1. Thus, the placement candidates 31 of the permanent sensor S1 can be appropriately determined in consideration of the positions where the permanent sensor S1 is not suitable for placement.

Figure 1 The sensor arrangement determination device 10 of the air conditioning control system 100 of the present embodiment shown in FIG. 1 is the same as that of the air conditioning control system 120 of the modification 1G, in which the sensor arrangement determination device 11 further includes an output unit 40. Figure 1 The sensor configuration shown determines that the device 10 is different.

[0213] The output unit 40 outputs the arrangement candidates 31 of the normal sensors S1 in the target space 80 and the arrangement candidates 32 of the training data acquisition sensors S2 in the target space 80 determined by the determination unit 30 .

[0214] The output unit 40 distinguishes between a plurality of sensors having different purposes, and outputs the sensor configuration candidates in the object space 80. In the modification 1G, the output unit 40 distinguishes between the normal sensor S1 and the training data acquisition sensor S2, and outputs the configuration candidate 31 of the normal sensor S1 in the object space 80 and the configuration candidate 32 of the training data acquisition sensor S2 in the object space 80.

[0215] In modification 1G, the target space may be, for example, the target space 82 including the air conditioner A, the ventilator B, and the like.

[0216] Fig.11 Show Figure 8 An example of the installation range of the permanent sensor S1 and the training data acquisition sensor S2 in the target space 82 is shown.

[0217] like Fig.11 As shown, the candidate 31 for the installation of the permanent sensor S1 is a position away from the air conditioners A1 to A4, the ventilation devices B1 and B2, the daily appliances C, the window D, the door E, and the personal computer F (not shown). The permanent sensor S1 is arranged at a height of 0.7 to 0.8 m from the ground to the table, for example.

[0218] In addition, a configuration candidate 32A of the training data acquisition sensor S2 is a position near the outlet of the ventilation device B1. In addition, a configuration candidate 32B of the training data acquisition sensor S2 is a position near the daily appliance C. In addition, a configuration candidate 32C of the training data acquisition sensor S2 is a position near the air conditioner A1 and near the window D.

In addition, a configuration candidate 32F of the training data acquisition sensor S2 is a position near the air conditioner A3. In addition, a configuration candidate 32G of the training data acquisition sensor S2 is a position near the air conditioner A4. In addition, a configuration candidate 32H of the training data acquisition sensor S2 is a position away from the outlet of the ventilation device B2. In addition, a configuration candidate 32I of the training data acquisition sensor S2 is a position away from the outlet of the ventilation device B2. The training data acquisition sensor S2 is disposed at a height position of, for example, 0.7 to 0.8 m, which is the height from the ground to the table.

[0219] In the sensor configuration determination device 11 of the modification 1G, by associating the model of the air conditioner A with the range of influence on the temperature (the range of influence of the airflow), or by storing other factors that affect the temperature and the range of influence on the temperature, and inputting information related to the elements that affect the temperature (air conditioner information, etc.), the range of influence of the factors that affect the environment in the space is calculated, and in the application of the air conditioner controller, personal computer, tablet computer and other equipment, the setting reference position of the constant sensor S1 and the sensor S2 for obtaining training data estimated according to the range of influence of the factor is displayed on the design drawing or CAD model. Thus, in order to correctly obtain the environment of the entire space or to control the target space, it is possible to prompt the sensor to be set at an appropriate position.

[0220] The purpose is to control air conditioners and ventilators, and measure and predict parameter distribution in space. By optimizing the location and number of installed environmental sensors, the control accuracy of air conditioners and ventilators can be improved, and the spatial parameter distribution can be accurately obtained. In addition, for the accuracy of temperature prediction as the target, no more sensors are installed than necessary, thereby reducing the purchase cost and management cost of sensors.

[0221] The air conditioning may be controlled using the measured environmental information (measured temperature information) obtained by the permanent sensor S1 installed at the position calculated by the sensor configuration determination device 11 of the modification 1G, or may be controlled using the predicted environmental information (predicted temperature information). Alternatively, the sensor configuration determination device 11 may be intended to obtain the environmental information (temperature information) of the target space 80, 82 by actual measurement or prediction.

[0222] In variant 1G, the optimal installation positions of the permanent sensor S1 and the sensor S2 for acquiring training data for the object spaces 80 and 82 are automatically selected and shown to the service engineer. The output unit 40 can prompt the recommended installation positions (ranges) of the permanent sensor S1 and the sensor S2 for acquiring training data in the application through the CAD model of the building, the BIM model, the architectural drawing, or the text. In addition, the recommended installation positions (ranges) of the permanent sensor S1 and the sensor S2 for acquiring training data can be set to be displayed in a form overlapped with an image such as a CAD model, an architectural drawing, or a camera image that visually shows the shape of the room through an application such as an air-conditioning controller or a user terminal, or in the form of text, and then displayed on the user terminal. In addition, the position (range) that is not suitable for the configuration of the permanent sensor S1 can also be prompted as a prohibited installation range for the permanent sensor S1.

[0223] In the sensor configuration determination device 11 of variant example 1G, the output unit 40 outputs the configuration candidates 31 of the permanent sensor S1 in the object space 80, 82 and the configuration candidates 32 of the sensor S2 for acquiring training data in the object space 80, 82 determined by the determination unit 30, thereby allowing the user to easily obtain the configuration candidates 31 of the permanent sensor S1 and the configuration candidates 32 of the sensor S2 for acquiring training data.

The constant sensor S1 is always installed in the target space 80. The training data acquisition sensor S2 acquires data related to the environment in the space and then collects it.

[0228] In the modification 1H, the output unit 40 can display the normal sensor S1 and the training data acquisition sensor S2 in a identifiable manner on an application of the user terminal, for example.

[0229] The user can specify the position of the constant sensor S1 . If the user specifies the position of the constant sensor S1 , the recommended position of the constant sensor S1 and the user's specified position are compared and displayed, and the user is informed that the accuracy of the target temperature prediction is reduced.

[0230] Furthermore, the output unit 40 outputs a notification of the time when the training data acquisition sensor S2 is recovered from the target space 80 or a notification of the time when the training data acquisition sensor S2 completes acquisition of data.

[0231] In the modification 1H, the target space may be, for example, the target space 82 including the air conditioner A, the ventilator B, and the like.

[0232] In the sensor configuration determination device 11 of the modification 1H, by obtaining the position of the permanent sensor S1 that is not suitable for configuration, it is possible to determine the configuration candidate 31 of the permanent sensor S1 and the configuration candidate 32 of the training data acquisition sensor S2 in consideration of the position of the not suitable for configuration.

[0244] It is also possible to divide the object space 84 into multiple areas within the range of air conditioners A with the same refrigerant piping system, and set one permanent sensor S1 in each area, thereby determining the number of permanent sensors S1, based on the shape and size of the object space 84 as the spatial information 22, the number of air conditioners A as the air conditioner information 21, and the accuracy of the target temperature prediction.

[0245] In Modification 1J, by determining the numerical value 33 of the constant sensor S1 in consideration of the information of the air conditioner A, the number 33 of the constant sensors S1 suitable for the target space 84 where the air conditioner A is installed can be determined.
