Description

The present invention relates to an air conditioning system or the like for air conditioning an air conditioned space.

Conventionally, energy saving has been performed in an air conditioning system (see, for example, Patent Document 1).

JP, 2008-281241, A

In the conventional air conditioning system, in the air conditioning of large-scale air-conditioned spaces such as underground malls, stations, airports, etc. that have an open area to the outside, the outflow of conditioned air from the open area and the inflow of outside air make the air conditioning inefficient and Was wasted. Further, for example, it is conceivable to install an air curtain in the open portion, but with an air curtain that forms a transverse airflow substantially parallel to the external opening surface, it is not possible to prevent outflow of conditioned air or inflow of outside air, and However, the air curtain may cause a pedestrian to feel uncomfortable, such as the hairstyle of a woman being broken.

Further, conventionally, the air-conditioned space as a whole has been uniformly air-conditioned. As a result, for example, air conditioning is performed even in places where there are no people, and energy is wasted by unnecessary air conditioning. There is also known a task/ambient air-conditioning system in which a work area and other areas are divided into a task area and an ambient area, respectively, and the air conditioning is performed by concentrating on the task area. However, in the task/ambient air conditioning, the task area and the ambient area are usually fixed, and it is not possible to switch them dynamically according to the situation of the air-conditioned space.

Also, in an air-conditioned space with many people's flow such as an underground mall or a station, comfort may deteriorate depending on the amount of heat generated by the person's exercise and the outside air attracted from the outside with the flow, Normally, uniform air conditioning was performed without considering such a situation. As a result, unnecessary air conditioning (for example, excessive cooling) is performed in order to improve comfort, and energy is wasted. On the other hand, in order to save energy, it is known to suppress the air conditioning set temperature (for example, 28 degrees during cooling, 20 degrees during heating, etc.), but there is a problem that comfort is deteriorated.

Generally speaking, there has been a demand for energy saving of air conditioning without impairing the comfort of people in the air-conditioned space.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an air conditioning system and a control method thereof that can save energy without impairing the comfort of people in an air-conditioned space.

In order to achieve the above object, an air conditioning system according to the present invention is an air conditioning system for an air conditioning space having one or more open parts to the outside, and acquires wind information regarding wind between the open part and the outdoor part. A sensor, an air conditioner that adjusts the temperature of the air, a supply unit that supplies the air whose temperature is adjusted by the air conditioner to the air conditioning space with a variable air volume from the supply port provided in the opening, and the air in the air conditioning space. At least the supply amount of the supply unit and the suction amount of the suction unit so that the air between the air-conditioned space indicated by the wind information acquired by the sensor and the outdoors is weakened, and the suction unit that sucks in a variable air amount from the suction port. And an air volume control unit for controlling one of them.
With such a configuration, the flow rate of air in the open portion can be reduced. As a result, it is possible to reduce the flow of conditioned air from the open portion and the flow of unpleasant air from the open portion, and it is possible to achieve energy saving for air conditioning of the air conditioned space. Further, for example, it is not necessary to provide an air curtain or the like in the opening portion, and it is possible to reduce the outflow of the conditioned air from the opening portion without causing a discomfort to passersby.

Further, the air conditioning system according to the present invention further includes an internal temperature sensor that acquires an internal temperature that is the temperature of the air-conditioned space, and an outdoor temperature sensor that acquires an outdoor temperature that is the outdoor temperature. If the outdoor temperature is on the target side of the temperature adjustment direction by the air conditioner with respect to the internal temperature, the wind direction acquired by the sensor is At least one of the supply amount of the supply unit and the suction amount of the suction unit is controlled so that the air flows into the air-conditioning space, and in other cases, the air-conditioned space indicated by the wind information acquired by the sensor and the outdoors. At least one of the supply amount of the supply unit and the suction amount of the suction unit may be controlled so that the wind between them becomes weak.
With such a configuration, it is possible to further save energy by appropriately using the outside air.

Further, in the air conditioning system according to the present invention, the air conditioning space is virtually divided horizontally into a plurality of compartments, and the air whose temperature is adjusted by the air conditioner is supplied to one or more compartments in the air conditioning space. Based on the plurality of division supply units provided for each of the above divisions, the pedestrian flow prediction unit that predicts pedestrian flow information that is information about pedestrian flow, and the pedestrian flow information that is predicted by the pedestrian flow prediction unit A partition control unit that controls the supply unit may be further included.
With such a configuration, the control for each section is performed based on the predicted pedestrian flow information. Therefore, for example, a section predicted to have a large number of people or a section predicted to have a high density of people is more likely to be cooled. By making it effective, it is possible to improve the comfort of passersby. Further, for example, in a section where it is predicted that the number of people will be small, energy saving can be achieved by weakening the effect of cooling. In addition, for example, even if the cooling is suppressed in this way, comfort is greatly impaired due to a small pedestrian flow (that is, because the heat load according to the occupant flow is small, the set temperature can be realized even if the cooling is suppressed). It will not happen. Further, when the air conditioning is controlled according to the result of sensing the pedestrian flow, there is a time lag between the control and the actual provision of the conditioned air to the conditioned space, and the conditioned air is supplied. Since there is a time lag due to the heat accumulation from the start to the set temperature, comfort of passersby may be reduced, but by controlling based on the predicted human flow information, such a time lag will not occur. It will be possible to improve the comfort. In addition, it becomes possible to dynamically change the air-conditioning status of a plurality of sections according to the predicted flow information.

Further, in the air conditioning system according to the present invention, a pedestrian flow acquisition unit for obtaining pedestrian flow information for each section, training input information including pedestrian flow information for a predetermined period acquired for each section, and a section after a predetermined period. Further, a storage unit that stores a learning device that is learned by using a plurality of sets of output information for training that is the human flow information acquired for each, and the human flow prediction unit is acquired by the human flow acquisition unit, The predicted crowd flow information may be acquired by applying the input information including the crowd flow information for a predetermined period to the learning device.
With such a configuration, it is possible to realize a more accurate prediction by predicting the people flow information using the learning device.

Further, in the air conditioning system according to the present invention, when the air conditioner is performing cooling, the compartment control unit has a large amount of supplied cold heat in a compartment having a large heat load indicated by the human flow information predicted by the human flow prediction unit. The section supply unit corresponding to the section is controlled so that the section supply unit corresponding to the section is reduced so that the amount of cold heat supplied to the section having a small heat load indicated by the human flow information predicted by the human flow prediction unit decreases. When the air conditioner is controlled and heating is being performed by the air conditioner, the section supply unit corresponding to the section is reduced so that the supplied heat quantity of the section having a large heat load indicated by the person flow information predicted by the person flow prediction unit is reduced. May be controlled, and the section supply unit corresponding to the section may be controlled so that the supplied hot energy amount of the section having a small heat load indicated by the people flow information predicted by the people flow prediction unit increases.
With such a configuration, comfort can be ensured. For example, during cooling, there is a large amount of human flow, so that the amount of supplied cold heat is controlled to increase in a section where the temperature rises, or the amount of supplied cold heat decreases in a section where the temperature does not rise due to a small amount of human flow. Because it is controlled. Further, by such control, the supply cold heat amount and the supply warm heat amount can be reduced in some of the sections, so that energy saving can be realized as compared with the case where uniform air conditioning control is performed.

Further, in the air conditioning system according to the present invention, the partition control unit does not supply the air adjusted by the air conditioner to the partition where the human flow information predicted by the human flow prediction unit indicates that there is no person, The compartment supply unit corresponding to the compartment may be controlled.
With such a configuration, energy saving can be realized by not performing air conditioning for a section that does not require air conditioning. Further, even if such control is performed, it is considered that comfort is unlikely to be impaired.

Further, in the air conditioning system according to the present invention, the air conditioned space is virtually divided into a plurality of blocks at least in the vertical direction, and a plurality of block temperature sensors provided for each block for acquiring the temperature of the block and a plurality of block temperature sensors are provided.

Further, in the air conditioning system according to the present invention, the air conditioned space is virtually divided into a plurality of blocks in the horizontal direction as well, and is provided with a plurality of ducts and a plurality of air blowers. In order to obtain pedestrian flow information including the average velocity, the inter-block air flow control unit confirms that the air of the block with the higher temperature among the blocks of the supply source has a low average velocity of the pedestrian flow according to the estimated pedestrian flow information. Is supplied to the block of the destination corresponding to the section indicated by, and the air of the cooler block is supplied to the block of the destination corresponding to the section where the predicted average flow rate of the human flow is high. You may control several ventilation parts so that it may be supplied.

The air conditioning system according to the present embodiment reduces the movement of air in the open portion, and appropriately uses the outside air appropriately. In addition, the air conditioning system according to the present embodiment uses the prediction result of the human flow for each section of the air-conditioned space to perform the control of the air conditioning for improving the comfort for each section. Further, the air conditioning system according to the present embodiment is intended to save energy by moving and effectively utilizing air in the air conditioned space.

1 and 2 are schematic diagrams showing the configuration of the air conditioning system 100 according to the present embodiment, and FIG. 3 is a block diagram showing the configuration of the air conditioning system 100. FIG. 4 is a top view of the air-conditioned space 200. Note that FIG. 1 mainly shows the configuration relating to the flow of conditioned air, FIG. 2 mainly shows the configuration relating to the movement of air in the conditioned space 200, and FIG. 3 shows the configuration relating to control. Mainly shown. The air-conditioned space 200 is a space to be air-conditioned by the air conditioning system 100.

As shown in FIGS. 1 to 3, the air conditioning system 100 according to the present embodiment includes an air conditioner 12, supply units 14a and 14b, a suction unit 18, sensors 31a and 31b, and an internal temperature sensor 32. The outdoor temperature sensor 33, the air volume control unit 34, the compartment supply units 41a to 41d, the laser range finders 42a to 42d, the human flow acquisition unit 43, the storage unit 44, the human flow prediction unit 45, and the partition control unit 46. The block temperature sensors 51a to 51h, the plurality of ducts 53, the air blowing units 54a to 54h, the dampers 55a to 55h, 56a to 56h, 57a to 57h, 58a to 58h, and the inter-block air blowing control unit 59. Further, when the supply unit 14a and the supply unit 14b are not particularly distinguished, the supply unit 14 may be simply referred to. The same applies to other components.

In addition, what is specified here is the main configuration, and the air conditioning system 100 has other configurations, such as the heat source device 11, the ducts 13 and 17, the supply port (blow-out port) 15, the suction ports 16 and 52, and the like. The dampers 19, 21 and the blower 20 may be provided.

In the present embodiment, in order to simplify the description, the air-conditioned space 200 is an underground mall having four sections 201a to 201d divided in the horizontal direction, and has open portions to the outside on the left and right end sides in FIG. The case will be described. The air-conditioned space 200 may be divided into other number of sections. For example, the number of sections may be two or three, or may be five or more.

In FIG. 1, the position of the open portion is indicated by a chain line. In addition, the number of opening portions included in the conditioned space 200 may be one or more, and may be three or more, for example. It is assumed that there is usually no door or the like in the open part and the part is left open. In addition, the air-conditioned space 200 may be a large-scale space such as an underground mall, an airport, or a station.

Further, in the present embodiment, as shown in FIG. 2, it is assumed that the air-conditioned space 200 has eight blocks 301a to 301h that are divided in the horizontal direction and the vertical direction. Blocks 301a to 301d are blocks on the upper side of the conditioned space 200, and blocks 301e to 301h are blocks on the lower side of the conditioned space 200. Note that, although FIG. 2 shows an example in which the air-conditioned space is vertically divided into two blocks, the air-conditioned space may be vertically divided into three or more blocks.

In the present embodiment, as shown in FIG. 4, the horizontal areas of the blocks 301a and 301e coincide with the horizontal areas of the partition 201a, and the horizontal areas of the blocks 301b and 301f are the partition areas. The horizontal areas of the blocks 301c and 301g coincide with the horizontal areas of the partition 201c, and the horizontal areas of the blocks 301d and 301h correspond to the horizontal area of the partition 201d. Although it is assumed that the area matches the horizontal area, the horizontal area of the block and the horizontal area of the partition may be determined independently.

Further, both the partition and the block are virtually set in the air-conditioned space 200. Therefore, in the real space of the air-conditioned space 200, walls or partitions may not exist at the boundaries of sections or the boundaries of blocks.

The air conditioner 12 adjusts the temperature of air. For the air conditioning, cold water or hot water supplied from the heat source device 11 having a boiler or a refrigerator may be used. In addition, the air conditioner 12 may perform, for example, humidity adjustment, ventilation, and air cleaning. The air conditioned by the air conditioner 12 is supplied to the supply unit 14 via the duct 13. In the present embodiment, the case where air conditioning is performed by the air supply method in the central method will be mainly described, but other methods, for example, the water/air combined supply method in the central method, the water supply method, and the refrigerant supply in the dispersion method It goes without saying that air conditioning may be performed depending on the method.

[Air volume control in open part]
First, the control of the air volume in the open part will be described.
The supply unit 14 supplies the air, the temperature of which is adjusted by the air conditioner 12, to the air-conditioned space 200 from the supply port 15 provided in the opening with a variable air volume. The supply unit 14 may be, for example, a variable air volume device (VAV: Variable Air Volume), a blower capable of adjusting the air volume by inverter control or the like, a combination of both, or an air volume. Other configurations capable of adjusting In the present embodiment, the case where the supply unit 14 is a variable air volume device will be mainly described. The provision of the supply port 15 of the supply unit 14 in the open portion means that it may be provided in the vicinity of the open portion. In addition, it is preferable that the supply port 15 of the supply unit 14 is provided closer to the air-conditioned space 200 than the open unit. When the air-conditioned space 200 has a plurality of open parts, it is preferable that at least one supply part 14 is provided in each of the open parts. When the air-conditioned space 200 is provided with a plurality of supply units, the supply unit having the supply port 15 at the opening may be considered to be the supply unit 14.

The suction unit 18 sucks the air in the air-conditioned space 200 from the suction port 16 with a variable air volume. The air sucked from the suction port 16 may be guided to the suction unit 18 via the duct 17 and returned to the air conditioner 12 from the suction unit 18, or may be discharged to the outside via the damper 19 and the blower 20. It may be exhausted. Whether the air from the suction port 16 is returned or exhausted can be changed by controlling the damper 19 and the blower 20. Further, a part of the air from the suction port 16 may be exhausted and a part thereof may be returned. Further, the suction unit 18 may be, for example, a variable air volume device, a blower capable of adjusting the air volume by inverter control or the like, a combination of the two, or another type capable of adjusting the air volume. It may be configured. In the present embodiment, the case where the suction unit 18 is a blower capable of adjusting the air volume by inverter control will be mainly described.

The sensor 31 acquires wind information regarding the wind between the air-conditioned space 200 in the open part and the outdoors. The wind information only needs to know at least the strength of the wind (that is, the strength of the movement of air), and may include, for example, the amount of air between the air-conditioned space 200 in the open part and the outdoors. It may include the velocity of the wind between the air-conditioned space 200 and the outside (wind velocity), and may include the direction of the wind between the air-conditioned space 200 and the outside in the open portion (wind direction). The wind direction may be, for example, a two-dimensional or three-dimensional wind direction. When the wind information includes the wind direction, the sensor 31 may acquire, for example, a two-dimensional or three-dimensional wind speed. Therefore, the sensor 31 may be, for example, an air flow sensor, an anemometer, or any other sensor capable of acquiring information about the wind. In the present embodiment, the case where the sensor 31 is an anemometer and the wind information includes the wind speed and the wind direction will be mainly described. The wind information acquired by the sensor 31 may be passed to the air volume control unit 34, for example, by wire or wirelessly.

The internal temperature sensor 32 acquires the internal temperature which is the temperature of the air-conditioned space 200. The internal temperature may be the temperature at any position as long as it is the temperature of the air-conditioned space 200, but is preferably the temperature at a position away from the open portion. Further, the internal temperature may be, for example, a representative value of measurement results of temperatures at a plurality of positions in the air-conditioned space 200. The representative value may be, for example, an average value or a median value. The internal temperature acquired by the internal temperature sensor 32 may be passed to the air volume control unit 34, for example, by wire or wirelessly.

The outdoor temperature sensor 33 acquires the outdoor temperature which is the outdoor temperature. The outdoor temperature may be the temperature at any position as long as it is the temperature outside the air-conditioned space 200, but is preferably the outdoor temperature near the open portion. This is because it is desired to know the temperature of the outside air flowing in from the open portion by the outdoor temperature. The outside air temperature may be, for example, a representative value of measurement results of temperatures at a plurality of outdoor positions. The representative value may be, for example, an average value or a median value. The outdoor temperature acquired by the outdoor temperature sensor 33 may be passed to the air volume control unit 34, for example, via a cable or wirelessly.

When the outdoor temperature is on the target side of the temperature adjustment direction by the air conditioner 12 (that is, the side after adjustment) with respect to the internal temperature, the air volume control unit 34 determines that the wind direction acquired by the sensor 31 is the open portion. At least one of the supply amount of the supply unit 14 and the suction amount of the suction unit 18 is controlled so that the air flows in the air-conditioned space 200 from outside. In addition, if not, that is, if the outdoor temperature is not on the target side in the direction of temperature adjustment by the air conditioner 12 with respect to the internal temperature, the air volume control unit 34 is indicated by the wind information acquired by the sensor 31. At least one of the supply amount of the supply unit 14 and the suction amount of the suction unit 18 is controlled so that the wind between the air-conditioned space 200 and the outside becomes weak. It should be noted that weakening of the wind between the air-conditioned space 200 and the outdoors means that the absolute value of the air volume or the wind speed becomes small, that is, the movement of air between the air-conditioned space 200 and the outdoors in the open portion is reduced. is there.

The temperature adjustment direction is a direction in which the temperature is decreased when the air conditioner 12 performs cooling, and is a direction in which the temperature is increased when heating is performed by the air conditioner 12. Therefore, in the case of cooling, the target side in the temperature adjustment direction is the low temperature side, and in the case of heating, the target side in the temperature adjustment direction is the high temperature side. More specifically, in the case where cooling is being performed, when the outdoor temperature is on the target side in the temperature adjustment direction with respect to the internal temperature, the external temperature is lower than the internal temperature, and the outdoor temperature is When the temperature is not on the target side in the temperature adjustment direction with respect to the internal temperature, the external temperature is higher than or equal to the internal temperature. Also, when heating is performed, when the outdoor temperature is on the target side in the temperature adjustment direction with respect to the internal temperature, the external temperature is higher than the internal temperature, and the outdoor temperature is higher than the internal temperature. Therefore, when the temperature is not on the target side in the temperature adjustment direction, the external temperature is lower than or equal to the internal temperature.

When the outdoor temperature is on the target side in the direction of temperature adjustment by the air conditioner 12 with respect to the internal temperature, the temperature in the same direction as the air conditioner 12 can be adjusted by introducing outside air into the air-conditioned space 200. Therefore, the control is performed so that the outside air is introduced, that is, the air flows in the air-conditioned space 200 from the outside at the opening portion. On the other hand, when the outdoor temperature is not on the target side in the direction of temperature adjustment by the air conditioner 12 with respect to the internal temperature, if the outside air flows into the air-conditioned space 200, the efficiency of air conditioning deteriorates, so that the internal temperature is increased at the open position. The air movement between the outside and the outside will be controlled to be small. It should be noted that the control in this case is ideally to prevent the movement of air between the inside and the outside at the position of the opening. On the other hand, if the movement of air between the inside and the outside of the open portion is smaller in the case where the control is performed than in the case where the control is not performed, it is considered that energy saving is achieved. Therefore, the air volume control unit 34 may thus perform control so that the movement of air between the inside and the outside of the open portion is reduced.

The control performed by the air volume control unit 34 may be control for changing the supply amount of the supply unit 14, control for changing the suction amount of the suction unit 18, or both. When it is desired to reduce the inflow amount of air from the outside to the inside of the open portion, the air volume control unit 34 may increase the supply amount of the supply unit 14 and/or decrease the suction amount of the suction unit 18. .. Further, when it is desired to increase the inflow amount of air from the outside to the inside in the opening part, or to reduce the outflow amount of air from the inside to the outside in the opening part, the air flow rate control unit 34 controls the supply unit 14. The supply amount may be reduced and/or the suction amount of the suction unit 18 may be increased. The control of the supply unit 14 and the suction unit 18 by the air flow control unit 34 may be performed by passing a control instruction from the air flow control unit 34 to the supply unit 14 and the suction unit 18 via wire or wireless.

Further, as will be described later, the conditioned air is supplied to the conditioned space 200 also by the plurality of compartment supply units 41, but the air volume control unit 34 supplies the conditioned air by the plurality of compartment supply units 41. The above-mentioned control may be performed in the state where is performed. Further, even when the outdoor temperature is on the target side in the direction of temperature adjustment by the air conditioner 12 with respect to the internal temperature, the air volume control unit 34 controls the strength of the wind in the open portion from the outdoor to the air-conditioned space 200. May be controlled so as not to exceed a predetermined upper limit.

Further, when the wind information does not include the wind direction, the air volume control unit 34 performs trial and error to reduce the absolute value of the air volume and the wind speed in the open portion, and the supply amount of the supply unit 14 and the suction unit. At least one of the suction amounts of 18 may be controlled. Specifically, when the air volume control unit 34 performs a certain control (for example, a control to increase the supply amount) and the absolute value of the air volume or the air velocity in the open portion increases, the opposite control (for example, , Control for reducing the supply amount) may be performed.

When the air-conditioned space 200 has a plurality of open parts and the supply part 14 is provided for each of the open parts, the control may be changed for each supply part 14. For example, in FIG. 1, when the sensor 31a indicates that there is a large inflow from the outside to the inside, and when the sensor 31b indicates that there is almost no movement of air between the inside and the outside, the air volume control unit 34 The air volume of the supply unit 14b may not be changed, and the air volume of the supply unit 14a may be controlled to be increased.

Further, in the present embodiment, as described above, a case will be mainly described in which outside air is appropriately introduced depending on the relationship between the internal temperature and the external temperature, but such outside air may not be introduced. .. When the outside air is not introduced, the air volume control unit 34 weakens the wind between the air-conditioned space 200 and the outside indicated by the wind information acquired by the sensor 31, regardless of the relationship between the internal temperature and the external temperature. Therefore, at least one of the supply amount of the supply unit 14 and the suction amount of the suction unit 18 may be controlled. In that case, the air conditioning system 100 may not include the internal temperature sensor 32 and the outdoor temperature sensor 33. In that case, the wind information does not have to include the wind direction.

[Air conditioning control according to forecasted flow of people in each section]
Next, the air conditioning control for each section performed according to the prediction result of the pedestrian flow for each section will be described.
The compartment supply unit 41 is provided for each of one or more compartments in the air-conditioned space 200. Then, the compartment supply unit 41 supplies the air whose temperature is adjusted by the air conditioner 12 to the one or more compartments. In the present embodiment, a case where one section is provided with one section supply unit 41 will be mainly described. More specifically, the compartment supply units 41a to 41d are provided in the compartments 201a to 201d, respectively, and supply the conditioned air to the compartments. Note that the provision of the compartment supply unit 41 in a certain compartment may be considered to mean that the compartment supply unit 41 supplies conditioned air to the compartment. It should be noted that the size or shape of the compartment does not matter. The shape of the partition may be, for example, a rectangular shape, a square shape, a polygonal shape, or the like. Further, when the partition has a rectangular shape, the length of one side is not particularly limited, but may be, for example, about 3 to 20 meters. Further, the areas of the plurality of sections may be, for example, the same or different.

When air conditioning is performed by the air supply system in the central system, the compartment supply unit 41 may supply the compartmented air with a variable air volume. Therefore, the compartment supply unit 41 may be, for example, a variable air volume device, a blower that can adjust the air volume by inverter control or the like, a combination of the two, or an air volume that can be adjusted. The configuration may be. In the present embodiment, a case where the compartment supply unit 41 is a variable air volume device will be mainly described.

The laser range finder (laser range sensor) 42 is a sensor that measures the distance in each of a plurality of directions. It is preferable that one laser range finder 42 can measure the distance over the entire area of one section. However, when the section is larger than the survey area, two or more laser range finders 42 are used. The distance may be measured over the entire area of one section. The measurement result obtained by the laser range finder 42 may be passed to the pedestrian flow acquisition unit 43, for example, by wire or wirelessly.

The people flow acquisition unit 43 acquires the people flow information for each section. People flow information is information about people flow. The pedestrian flow information of a section may include, for example, the total passing time per unit time in the section, or may include the number of passers-by per unit time in the section. The total travel time per unit time in a certain section is the sum of the unit time regarding the travel time for each passerby in the section. For example, within a period corresponding to a unit time, a first passer passes through a section in 10 seconds, a second passer in 5 seconds, and a third passer in 15 seconds. In this case, the total transit time per unit time in that section is 30 seconds (=10+5+15). In addition, the number of passers-by per unit time in a certain section is the total number of passers-by per unit time in that section. In the above example, there are three people. When the areas of the plurality of sections are not equal, the pedestrian flow information may be a value considering the area, for example, a value per unit area. Therefore, the people flow information may be, for example, the density of people.

There is known a pedestrian flow measurement system that estimates the flow line of a passerby by using the measurement result of the laser range finder 42. For the human flow measuring system, refer to, for example, JP-A-2016-009281. By using the same method, the pedestrian flow acquisition unit 43 can obtain the flow line of each passerby based on the measurement result of the laser range finder 42 corresponding to a certain section, and obtain the total pass time and the number of passersby. Can be obtained.

In the present embodiment, the case where the pedestrian flow information is acquired using the measurement result of the laser range finder 42 will be mainly described, but the pedestrian flow acquisition unit 43 acquires the pedestrian flow information by using the measurement result of another sensor or the like. You may get it. In that case, the air conditioning system 100 may include, for example, another sensor or the like used in acquisition of human flow information, instead of the laser range finder 42.

The pedestrian flow acquisition unit 43 may acquire pedestrian flow information using, for example, an image captured by a camera. In that case, the pedestrian flow acquisition unit 43 can obtain the flow line of each passerby by recognizing a person and tracking the recognized person in a moving image that is a captured image. Similarly, the total transit time and the number of passers-by can be acquired. In addition, when a photographed image is used, the attributes of the passerby (for example, sex, age, etc.) can be acquired. Therefore, in this case, the pedestrian flow acquisition unit 43 may acquire pedestrian flow information including, for example, the distribution of the attributes of passersby (for example, the ratio of sex and the ratio of each age).

The human flow acquisition unit 43 may acquire the human flow information using, for example, an image captured by a thermo camera. In that case, the pedestrian flow acquisition unit 43 can obtain the flow line of each passerby by recognizing a person and tracking the recognized person in an image captured by a thermo camera, for example. Similarly, the total transit time and the number of passers-by can be acquired.

In addition, when there are a plurality of approach routes to a certain section, for example, when there is an approach route from the outside or an approach route from a store, the pedestrian flow acquisition unit 43 distributes the approach routes (for example, for each approach route). Information such as the ratio of the above) may be acquired.

Further, the pedestrian flow acquisition unit 43 may acquire information other than the pedestrian flow information which is information to be input to the learning device in the pedestrian flow prediction using the learning device described later. For example, as will be described later, attribute information about a time point corresponding to the pedestrian flow information input to the learning device may be acquired, and a time point corresponding to the pedestrian flow information output from the learning device (for example, within a predetermined period from the present time). Attribute information regarding (for example, time point of). The time point may be, for example, a pinpoint time point, or may be a period having a width. The attribute information may include, for example, information about time at a time corresponding to the attribute information (hereinafter, referred to as “time information”), and information about weather at a time corresponding to the attribute information (hereinafter, “weather”).

The weather information may include, for example, weather such as fine weather, cloudy weather, and rain, may include temperature, may include humidity, may include wind speed, and may include daylight hours. It may also include other information about the weather. The weather, temperature, humidity, wind speed, sunshine duration, etc. are usually information outdoors near the air-conditioned space 200. The pedestrian flow acquisition unit 43 may acquire the weather information from, for example, a website such as the Meteorological Agency or a sensor or the like that acquires the weather, temperature, or the like. The weather information about the time point corresponding to the pedestrian flow information output from the learning device may be, for example, information predicted about the weather.

The event information may include, for example, information regarding an event inside the air-conditioned space 200, may include information regarding an event outside the air-conditioned space 200, and information regarding transportation within the air-conditioned space 200 or outside the air-conditioned space 200. May be included and may include other information about the event. The information regarding the event inside the air-conditioned space 200 and the information regarding the event outside the air-conditioned space 200 include, for example, the presence/absence of an event indicating whether or not there is an event at a corresponding time, the event of a large scale, a medium scale, or a small scale. It may include the scale, type of event such as fireworks display, festival, baseball game, soccer game, and the like. The information about transportation may include, for example, the presence/absence of a delay at a corresponding time point, the number of getting on/off vehicles, the presence/absence of departure/arrival of a train or a bus, and the like. The pedestrian flow acquisition unit 43 may acquire the event information from, for example, a website on which information about the event is posted, or may be acquired by reading information manually input by an administrator or the like.

When the attribute information is also acquired, the pedestrian flow acquisition unit 43 may acquire the attribute information at the time point corresponding to the pedestrian flow information when the pedestrian flow information is acquired. The acquired attribute information may be stored in a recording medium (not shown) in association with the flow information, for example. In addition, when the pedestrian acquisition unit 43 acquires the pedestrian information using a learning device, the pedestrian acquisition unit 43 may acquire attribute information regarding a time point corresponding to the pedestrian information output from the learning device.

The storage unit 44 stores a learning device. This learning device uses a plurality of sets of training input information including the people flow information acquired for each section for a predetermined period and training output information that is the people flow information acquired for each section after the predetermined period. Have been learned by The set of the training input information and the training amount output information may be called training information.

The time point corresponding to the pedestrian flow information included in the training output information may be immediately after the last time point corresponding to the pedestrian flow information included in the training input information paired with the training output information. In that case, for example, in the training input information, the people flow information of 8:00 to 8:30, the people flow information of 8:30 to 9:00, the people flow information of 9:00 to 9:30, and 9 The person flow information of :30 to 10:00 may be included, and the person output information of 10:00 to 10:30 may be included in the training output information that is paired with the training output information.

On the other hand, the time point corresponding to the pedestrian flow information included in the training output information may not be immediately after the last time point corresponding to the pedestrian flow information included in the training input information paired with the training output information. In that case, for example, in the training input information, the person flow information of 8:00 to 8:30, the person flow information of 8:30 to 9:00, and the person flow information of 9:00 to 9:30 on a certain day. And the crowd information of 9:30 to 10:00 is included, and the training output information paired with the training output information includes the crowd information of 9:30 to 10:00 one week after the day.

The training input information may include attribute information about the time point corresponding to the pedestrian flow information included in the training input information, and corresponds to the pedestrian flow information included in the training output information paired with the training input information. Attribute information regarding a time point to be performed may be included. For example, when the training input information includes people flow information corresponding to a plurality of time points, the training input information may include attribute information about each time point, or attribute information about some time points. May be included. When the training output information includes human flow information corresponding to a plurality of time points, the training input information paired with the training output information may include attribute information about each time point, or The attribute information regarding some time points may be included.

The learning device may be, for example, a learning result of a neural network (NN), and may be a learning result of a support vector machine (SVM) or a support vector regression (SVR). Alternatively, it may be the learning result of other machine learning.

The neural network may be, for example, a convolutional neural network (CNN: Convolutional Neural Network), or may be another neural network (for example, a neural network including fully connected layers). A convolutional neural network is a neural network having one or more convolutional layers. If the neural network has at least one intermediate layer (hidden layer), the learning of the neural network may be considered to be deep learning. When a neural network is used for machine learning, the number of layers of the neural network, the number of units in each layer, the type of each layer (eg, convolutional layer, fully connected layer, etc.) can be selected appropriately. Good. The number of units in the input layer and the output layer is usually determined by the training input information and the training output information included in the training information. In the present embodiment, the case where the learning device is the learning result of CNN will be mainly described, and the other cases will be described later.

Note that the learning device stored in the storage unit 44 may mean that the learning device itself (for example, a function that outputs a value with respect to an input, a model of a learning result, or the like) is stored. It may well be that information such as parameters necessary for configuring the learning device is stored. Even in the latter case, the learning device can be configured by using the information such as the parameters, so that it can be considered that the learning device is substantially stored in the storage unit 44. In the present embodiment, a case where the learning device itself is stored in the storage unit 44 will be mainly described.

The process of storing the learning device in the storage unit 44 does not matter. For example, the learning device may be stored in the storage unit 44 via a recording medium, or the learning device transmitted via a communication line or the like may be stored in the storage unit 44. The storage in the storage unit 44 may be a temporary storage such as a RAM or a long-term storage. The storage unit 44 can be realized by a predetermined recording medium (eg, semiconductor memory, magnetic disk, optical disk, etc.).

Here, the generation of the learning device will be described. FIG. 5 is a block diagram showing the configuration of learning device manufacturing apparatus 400 according to the present embodiment. The learning device manufacturing apparatus 400 according to the present embodiment includes a training information receiving unit 401, a learning device manufacturing unit 402, and a learning device output unit 403. The learning device manufacturing apparatus 400 is usually an information processing apparatus that performs learning, but may be a general-purpose apparatus such as a portable information processing terminal or a dedicated apparatus that performs learning, for example. It may be a server or the like.

The training information reception unit 401 is a set of training input information including the human flow information of a predetermined period acquired for each section, and training output information that is the human flow information acquired for each section after the predetermined period. Accept multiple. The training input information may include the above attribute information. As described above, the attribute information may include attribute information regarding a time point corresponding to the pedestrian flow information included in the training input information, and attribute information regarding a time point corresponding to the pedestrian flow information included in the training output information may be included. May be included. Further, attribute information other than the above may be included in the training input information. Specifically, as will be described later with reference to FIG. 11A, attribute information indicating whether or not each section includes a passage that is an air-conditioned space may be included in the training input information.

A plurality of training information may be configured by using the pedestrian flow information and the attribute information acquired by the pedestrian flow acquisition unit 43. For example, when the crowd information and the attribute information are acquired every 30 minutes, the crowd information for two consecutive hours, that is, four crowd information is included in the training input information, and 30 minutes immediately after the two hours. It is possible to prepare the training information including the minute flow information in the training output information. Further, the attribute information corresponding to each of the four people flow information included in the training input information may be included in the training input information, and the attribute information corresponding to a part of the four people flow information may be input for training. It may be included in the information. In addition, the training input information may include attribute information corresponding to one person flow information included in the training output information. Further, by shifting the time zone every 30 minutes, it is possible to prepare other training information. In this way, a plurality of training information can be prepared and input to the training information receiving unit 401.

In addition, the number of people flow information included in the training input information may be, for example, one, or two or more, and the number is not limited. Further, the pedestrian flow information included in the training input information may be, for example, pedestrian flow information for several hours or one week, and the period is not limited. Further, when the training input information includes a plurality of people flow information, the plurality of people flow information may correspond to consecutive periods.

Further, the number of people flow information included in the training output information may be, for example, one, or two or more, and the number thereof does not matter. Further, the crowd information included in the training output information may be, for example, crowd information for about 30 minutes, crowd information for about 1 hour, or crowd information for about 1 day. , The period does not matter. When the training output information includes a plurality of people flow information, the plurality of people flow information may correspond to a continuous period.

Further, the training input information includes attribute information corresponding to the pedestrian flow information included in the training input information, but does not include the attribute information corresponding to pedestrian flow information included in the training output information. Of course, conversely, the attribute information corresponding to the people flow information included in the training input information is not included, but the attribute information corresponding to the people flow information included in the training output information may be included. Further, the training input information may include both attribute information corresponding to the pedestrian flow information included in the training input information and attribute information corresponding to the pedestrian flow information included in the training output information.

When the training input information includes attribute information corresponding to a plurality of people flow information, and the attribute information common to the plurality of people flow information is one attribute corresponding to a plurality of people flow information. It may be summarized in information. For example, when the training input information includes four people flow information, the training output information includes one traffic flow information, and the corresponding season information and time information such as month and day of the week are common. May include one piece of time information corresponding to five pieces of people flow information in the training input information. For attribute information that changes with the passage of time, such as weather information, it is preferable that the attribute information corresponding to each person flow information be included in the training input information.

Hereinafter, the training information in the case where the machine learning is the machine learning of the convolutional neural network will be specifically described.
FIG. 9A is a diagram showing an example of a map of an underground mall, which is an air-conditioned space having an opening. In FIG. 9A, the region of the air-conditioned space that is a passage is indicated by diagonal lines. FIG. 9B is a diagram showing a state in which the underground mall shown in FIG. 9A is divided into a plurality of sections. As shown in FIG. 9(b), the map of the underground mall shown in FIG. 9(a) is divided into 10 sections in the width direction and 5 sections in the height direction, and has a total of 50 sections. Become. Among them, there are 16 passage sections that are air-conditioned spaces. In addition, here, the section including a part of the passage is assumed to be the section of the passage.

For example, as shown in FIG. 9C, information having different values for each section, such as people flow information, has a 10×5 matrix (image) having values for each corresponding section. However, 0 is set for the sections other than the air-conditioned space. In this case, the information of one section is the information of one pixel. Further, the value of the people flow information is normalized so as to be a value from 0 to 1. That is, the map of the air-conditioned space is divided into grids, one section corresponds to one pixel, and information of one section (for example, pedestrian flow information) corresponds to the pixel value of one pixel. The input information will be configured in. It is preferable that the quantitative information such as temperature and humidity other than the human flow information is also normalized so as to have a value of 0 to 1. On the other hand, the qualitative information may be converted into a binary variable and included in the training information. It should be noted that, as in the case of quantitative information or qualitative information in which binary variables are used, if the value changes for each section, as in FIG. It may be included in the training information as a different image. For example, when an event occurs in a part of the air-conditioned space, information indicating the presence or absence of the event for each section may be used as the event information. Further, in the event information, a numerical value according to the scale of the event may be used as quantitative information instead of the information indicating the presence or absence of the event. On the other hand, for information whose value does not change for each section, for example, for attribute information such as time information and weather information, an image in which all pixel values are “0” or an image in which all pixel values are “1” is used. May be expressed. That is, for information whose value does not change for each section, an image in which all pixel values are the same may be used as input information. The same applies to the output information. In the following description, W×H is the image width×height. Further, when written as W×H×C, C indicates the number of channels.

Is the personal flow information of 9:00 to 9:30 on the same day, and FIG. 10D is the personal flow information of 9:30 to 10:00 on the same day. In FIG. 10, the values are shown on the map of the underground mall, but the pedestrian flow information included in the training input information is a 10×5 image. Therefore, in this case, the flow information included in the training input information is a 10×5×4 image.

In addition, when the pedestrian flow information is both the total traffic time and the number of passers-by, an image corresponding to the total traffic time and an image corresponding to the number of passers-by are required. The included flow information may be a 10×5×8 image. When the traffic information includes the distribution of the sexes of the passersby, the traffic information indicating the distribution of the sexes may also be a 10×5×4 image.

FIG. 11A is attribute information indicating whether each section includes an air-conditioned space (that is, a passage). In FIG. 11A, “1” is set in the section including the passage which is the air-conditioned space, and “0” is set in the other sections. In addition to the image shown in FIG. 11A, in the air-conditioned space where “0” is set in the section including the passage which is the air-conditioned space and “1” is set in the other sections. Attribute information indicating a section that does not include a certain passage may also be included in the training input information. If both are included in the training input information, the number of channels will increase by two. The attribute information indicating whether or not the air-conditioned space is included in each section does not have to be used when the people flow prediction is performed only in the passage of the underground mall shown in FIG. 9A. It is suitable to be used when people flow prediction is performed for two or more different areas.

FIG. 11B is a diagram showing an example of attribute information indicating the month at the time corresponding to the people flow information. As shown in FIG. 11B, when the time corresponding to the people flow information is June, each value of the image corresponding to June is “1”, and the value of the image corresponding to the other months is “1”. Each value may be set to "0". In this case, the 12-channel image can be used to show the month at the time corresponding to the flow information.

FIG. 11C is a diagram showing an example of attribute information indicating a day of the week at a time corresponding to the people flow information. As shown in FIG. 11C, when the time corresponding to the people flow information is Sunday, each value of the image corresponding to Sunday becomes “1”, and each value of the image corresponding to other days of the week May be set to be “0”. In this case, the 7-channel image can be used to indicate the day of the week corresponding to the flow information.

FIG. 12A is a diagram showing an example of attribute information indicating whether the time point corresponding to the people flow information is a weekday or a holiday. As shown in FIG. 12A, when the time corresponding to the people flow information is a weekday, each value of the image corresponding to the weekday is “1”, and each value of the image corresponding to the holiday is “0”. May be set so that In this case, a 2-channel image can be used to indicate whether the time point corresponding to the people flow information is a weekday or a holiday.

FIG. 12B is a diagram showing an example of attribute information indicating whether the time corresponding to the people flow information is early morning, morning rush, mid-morning zone, daytime, mid-afternoon zone, evening rush, night, or midnight. Is. As shown in FIG. 12B, when the time point corresponding to the people flow information is in the morning mid-zone, each value of the image corresponding to the morning mid-zone is "1", and it corresponds to other time zones. Each value of the image to be displayed may be set to “0”. In this case, an 8-channel image can be used to indicate the time zone at the time corresponding to the flow information.

FIG. 12C is a diagram showing an example of attribute information indicating weather at a time corresponding to the people flow information. As shown in FIG. 12C, when the weather at the time corresponding to the pedestrian flow information is cloudy, each value of the image corresponding to cloudy is “1”, and each of the images corresponding to clear and rainy is The value may be set to “0”. In this case, the weather at the time corresponding to the people flow information can be shown by using the image of three channels.

FIG. 12D is a diagram showing an example of attribute information indicating the outside air temperature at the time corresponding to the people flow information. As shown in FIG. 12D, when the outside air temperature is 25° C. at the time corresponding to the human flow information, each value of the image corresponding to the outside air temperature is “0. 65" may be set. In this case, the one-channel image can be used to show the outside air temperature at the time corresponding to the pedestrian flow information. Therefore, when the training input information includes the outside temperature, the outside humidity, the wind speed, and the sunshine duration, the information may be a 4-channel image.

FIG. 13 is a diagram showing an example of one person flow information included in the training output information. FIG. 13 shows the personal flow information from 10:00 to 10:30 on the same day as FIGS. 10(a) to 10(d). The people flow information shown in FIG. 13 is a 10×5 image. If the training input information includes both the pedestrian flow information indicating the total traffic time and the pedestrian flow information indicating the number of passers-by, the training output information may include both pedestrian flow information. Good. In that case, the pedestrian flow information included in the training output information may be a 10×5×2 image. Further, when the training input information includes the pedestrian information indicating the gender distribution of the passersby, the training output information may also include the pedestrian information indicating the gender distribution of the passersby. The pedestrian flow information indicating the distribution of gender included in the training output information may be a 10×5 image.

For example, the training input information includes the image of the 4-channel human flow information shown in FIG. 10, the image of the 2-channel corresponding to FIG. 11A, and the images shown in FIGS. If images of 21 channels in total corresponding to c) and FIG. 12A are included, the total of them is 27 channels. Further, the 8-channel image corresponding to FIG. 12B, the 3-channel image corresponding to FIG. 12C, and the outside air temperature, the outside humidity, the wind speed, and the sunshine duration related to FIG. If a 4-channel image is included for each of the five pedestrian information included in the input and output, the total of them is 75 (=15×5) channels. As a result, the images included in the training input information have a total of 102 channels. Therefore, for example, the training input information includes a 10×5×102 image, and the training output information includes a 10×5×1 image. A plurality of such training information will be prepared.

The training information reception unit 401 may receive information transmitted via a wired or wireless communication line, for example, and is read from a predetermined recording medium (eg, optical disk, magnetic disk, semiconductor memory, etc.). Information may be accepted. The training information receiving unit 401 may or may not include a device (for example, a modem or a network card) for receiving the training information. The training information receiving unit 401 may be realized by hardware or software such as a driver that drives a predetermined device.

The learning device manufacturing unit 402 manufactures a learning device by learning a plurality of sets of training input information and training output information. This learning device includes a plurality of sets of training input information including pedestrian flow information acquired for each section during a predetermined period, and training output information that is pedestrian flow information acquired for each section after the predetermined period.

Therefore, for example, when input information including human flow information for a predetermined period is applied to this learning device, output information that is the human flow information for each section after the period corresponding to the human flow information included in the input information is output. Obtainable. It is preferable that the input information includes the same information as the training input information. For example, when the training input information includes attribute information, it is preferable that the input information also includes similar attribute information. More specifically, when the training input information is a 10×5×102 image, the input information is also preferably a 10×5×102 image. The details of this learning will be described later.

The learning device output unit 403 outputs the learning device manufactured by the learning device manufacturing unit 402. The learning device output by the learning device output unit 403 is stored in the storage unit 44 of the air conditioning system 100 shown in FIG. Here, this output may be, for example, transmission to a predetermined device via a communication line, storage in a recording medium, or delivery to another component. The learning device output unit 403 may or may not include a device (for example, a communication device) that outputs. The learner output unit 403 may be realized by hardware or software such as a driver for driving those devices.

Next, machine learning performed by the learning device manufacturing unit 402 will be described. This machine learning may be learning with a teacher, learning of a neural network, learning of support vector machines or support vector regression, or other machine learning. Here, the case where the machine learning is learning of a neural network will be mainly described.

Further, the number of layers of all connected layers included in the neural network does not matter. For example, the neural network may have one fully connected layer, may have two or more consecutive fully connected layers, or may have three or more consecutive fully connected layers. ..

Further, padding may be appropriately performed in each layer of the neural network. The padding may be, for example, zero padding, extrapolation of the pixel values at the outermost periphery of the image, or padding with pixel values folded at each side of the image. FIG. 14 shows an example in which padding of size 1 is performed on two convolutional layers. The filter size (2×2) in the pooling layer indicates the pooling size. The pooling may be, for example, maximum value pooling, average pooling, or other pooling. Maximum pooling was used in the experiments described below.

The stride in each layer is not limited, but the stride in the convolutional layer is preferably a small value such as 1 or 2, and the stride in the pooling layer is preferably 2 or more.

Further, a bias may or may not be used in each layer. Whether to use the bias may be determined independently for each layer. The bias may be, for example, a layer-by-layer bias or a filter-by-filter bias. In the former case, one bias is used in each layer, and in the latter case, one or more (the same number as the filters) bias is used in each layer. When the bias is used in the convolutional layer, the result obtained by multiplying each pixel value by the filter parameter and adding the result to the bias is input to the activation function.

Each setting in the neural network may be as follows. The activation function may be, for example, ReLU (normalized linear function), a sigmoid function, or another activation function. In learning, for example, the error back propagation method or the mini-batch method may be used. The loss function (error function) may be a mean square error. Further, the number of epochs (the number of times the parameters are updated) is not particularly limited, but it is preferable to select the number of epochs that does not cause overfitting. A known method can be used as a learning method in machine learning, and a detailed description thereof will be omitted.

It should be noted that although the present embodiment mainly describes a case where the human flow information input to the neural network is in the form of an image, it does not have to be so. For example, the pedestrian flow information is information about pedestrian flow for each section, and may not be image-like information. In that case, for example, in the example shown in FIG. 9 and the like, information whose value changes for each section, for example, for the personal flow information, the number of channels multiplied by the number of sections (16 in FIG. 9) For information whose value does not change for each section, the amount of information corresponds to the number of channels. Further, in this case, the information of the two channels corresponding to FIG. 11A becomes unnecessary. Therefore, the number of information to be input is 64 (=4×16) corresponding to 4-channel human flow information and 96 corresponding to 96-channel other information, and the number of units in the input layer is 160. (=64+96). In this case, all layers of the neural network may be fully connected layers. The total number of bonding layers may be, for example, two, three, or four or more. According to an experiment by the inventors of the present application, as shown in FIG. 9 and the like, the accuracy of prediction is higher when the input information is image-like information than when it is not. Although the detailed reason is unknown, it is likely that by inputting the pedestrian flow information as shown in FIG. 9C, the adjacency situation of each section will be learned, and as a result, the prediction It is speculated that the accuracy may have improved.

Further, even when the convolutional neural network is used, for example, in the example of FIG. 9 or the like, learning may be performed using the pedestrian flow information in which 16 sections are converted into 4×4 images. In that case, it is preferable that the 4×4 input image is configured such that the partitions that are close to each other in the real space are close to each other in the input image. Even in this case, it is considered that the accuracy may be lower than that in the learning in the convolutional neural network using the information of FIG. 9 and the like.

As described above, a learning device other than the neural network, which is a learning result, may be used as the learning device. For example, a learning device that is a learning result of SVM or SVR may be used. In that case, for example, learning may be performed for each section. Specifically, when the air-conditioned space is divided into 16 compartments, 16 learners corresponding to the 16 compartments are manufactured, and 16 learners are used for the human flow prediction of the 16 compartments. May be used. As the input information and the output information in that case, the same input information and the output information as described above can be used except that the input information and the output information in the learning of the neural network described above are the information for each section. In addition, when predicting the people flow information by using the SVM, the people flow information is classified into a plurality of stages (for example, 3 stages, 5 stages, etc.), and the SVM multi-value classification method is used to calculate the people flow information. You may make it predict the stage regarding.

Returning to FIG. 3, the people flow predicting unit 45 acquires the predicted people flow information by applying the input information, which is acquired by the people flow acquiring unit 43 and includes the people flow information for a predetermined period, to the learning device. The image size and the number of information items of the input information are preferably the same as the image size and the number of information items of the training input information. Therefore, the input information may include attribute information, like the training input information, for example. The attribute information may be acquired by the human flow acquisition unit 43, for example, as described above. By inputting the input information to the learning device, the people flow predicting unit 45 can acquire the output information that is the output of the learning device, that is, the predicted people flow information. When the storage unit 44 stores a function or model that is a learning device, the pedestrian flow prediction unit 45 obtains output information by performing calculation using the function or model of the captured image. Good.

Further, the pedestrian flow prediction unit 45 may acquire pedestrian flow information including the average velocity of the pedestrian flow. This average speed may be an average value of speeds for each passerby in a certain section. For example, when the pedestrian flow information includes the total traffic time per unit time of a certain section and the number of passers-by per unit time, the pedestrian flow is calculated as follows using the length of the section in the traffic direction. The average speed of can be calculated.
Average speed of pedestrian flow = length of section in the direction of traffic x number of pedestrians per unit time / total transit time per unit time

If the compartment is a passage extending in one direction, the length of the compartment in the passage direction is the length of the passage extending in the one direction. On the other hand, when the section is not a passage that extends in one direction, such as a crossroads or a corner, the average length of the traffic direction is specified in consideration of the traffic characteristics of the passerby, and the specified traffic flow is determined. The length of direction may be used to calculate the average velocity. Further, when the average speed of the pedestrian flow can be calculated using the pedestrian flow information, it may be considered that the pedestrian flow information includes the average speed of the pedestrian flow. In that case, it is considered that it is equivalent to including the average speed itself of the people flow in the people flow information. Specifically, as described above, when the pedestrian flow information includes the number of pedestrians and the total travel time, it may be considered that the pedestrian flow information includes the average speed of the pedestrian flow.

In the present embodiment, a case will be mainly described in which the people flow is predicted using the learning device, but the people flow predicting unit 45 does not use the learning device and collects the people flow information that is the information about the people flow for each section. You may predict. Specifically, the flow of people may be predicted based on a model that there is a periodicity such as a one-week cycle or a yearly cycle in the flow of people, using the history of the people flow information for each section. In that case, the people flow predicting unit 45 may acquire, for example, the people flow information about the people flow one week before or the year before the prediction target time as the predicted people flow information. In addition, other methods of predicting the flow of people may be used to predict the flow of people. For other methods, refer to, for example, JP-A-2018-195215. In this way, when the human flow prediction is performed without using the learning device, the air conditioning system 100 does not have to include the storage unit 44. In addition, when the pedestrian flow information that is acquired by the pedestrian flow acquisition unit 43 is not used for the pedestrian flow prediction that does not use the learning device, the air conditioning system 100 may not include the pedestrian flow acquisition unit 43.

The partition control unit 46 controls the plurality of partition supply units 41 based on the pedestrian flow information predicted by the pedestrian flow prediction unit 45. The control of the plurality of section supply units 41 based on the predicted person flow information means that at least the person flow information is used to control the plurality of section supply units 41. Therefore, as will be described later, for example, the pedestrian flow information may be directly used for the control, or the calorific value calculated using the pedestrian flow information may be used. The control of the partition supply unit 41 by the partition control unit 46 may be performed by passing a control instruction from the partition control unit 46 to the partition supply unit 41 via wire or wireless.

The control may be, for example, to perform different control for a section having a large heat load and a section having a small heat load according to human flow. For example, when the air conditioner 12 is performing cooling, the partition control unit 46 increases the supplied cold heat amount of a partition having a large heat load, which is indicated by the human flow information predicted by the human flow prediction unit 45. The section supply unit 41 corresponding to the section is controlled such that the section supply unit 41 corresponding to the section is controlled so that the supplied cold heat amount of the section having a small heat load indicated by the person flow information predicted by the person flow prediction unit 45 is small. May be controlled. Further, for example, when the air conditioner 12 is heating, the partition control unit 46 reduces the amount of supplied heat and heat in a partition having a large heat load, which is indicated by the human flow information predicted by the human flow prediction unit 45. In addition, the section supply unit 41 corresponding to the section is controlled so that the section supply corresponding to the section is increased so that the supply heat quantity of the section having a small heat load indicated by the human flow information predicted by the human flow prediction unit 45 increases. The part 41 may be controlled. The section having a large heat load indicated by the predicted people flow information may be, for example, a section in which the people flow indicated by the predicted people flow information is larger than the first threshold value, and is calculated using the predicted people flow information. The section in which the generated heat amount is larger than the third threshold value may be used. Further, the section having a small heat load indicated by the predicted people flow information may be, for example, a section in which the people flow shown by the predicted people flow information is less than the second threshold value, and the predicted people flow information is used. It may be a section where the calorific value calculated by the calculation is smaller than the fourth threshold value. The first and second thresholds may be, for example, the same value, or the first threshold may be greater than the second threshold. Further, the third and fourth thresholds may be the same value, for example, or the third threshold may be larger than the fourth threshold. Moreover, the partition supply part 41 corresponding to a certain partition is the partition supply part 41 that supplies conditioned air to the partition. Since the flow of people is predicted for each section, it can be considered that a large flow of people means a high density of people, and a low flow of people means a low density of people.

For example, it is known that the amount of heat generated from the human body of a passerby walking at 4.8 (km/h) is 276.8 (W). For the amount of heat generation, refer to the following documents, for example. Therefore, as the number of people in a certain section increases, the amount of heat generated by passersby also increases, and the temperature in that section rises. Therefore, it is possible to calculate the calorific value according to the human flow for each section by using the predicted human flow information, and the calculated calorific value may be used for the above control by the section control unit 46. Further, as described above, it is possible to control the temperature of a section with a large amount of pedestrians to be low and the temperature of a section with a small amount of pedestrians to be high so that the pedestrians in each section are comfortable. Appropriate control to improve.

In order to perform control according to the heat generation amount of a passerby, the partition control unit 46, for example, when cooling is being performed, the partition control unit 46 puts the air conditioner 12 into a partition having a large heat load indicated by the predicted human flow information. The compartment supply unit 41 corresponding to the compartment may be controlled so that more conditioned air is supplied, and the compartment from which the conditioned air is supplied from the air conditioner 12 has a smaller heat load indicated by the predicted human flow information. The compartment supply unit 41 corresponding to the compartment may be controlled so that the compartment is supplied less. Further, since the control according to the heat generation amount of the passerby is performed, the partition control unit 46, for example, when the heating is performed, the air conditioner 12 is installed in a partition having a large heat load indicated by the predicted human flow information. The compartment supply unit 41 corresponding to that compartment may be controlled so that less conditioned air is supplied from the air conditioner 12 to the compartment having a smaller heat load indicated by the predicted human flow information. The compartment supply unit 41 corresponding to the compartment may be controlled so that more air is supplied. Note that supplying more conditioned air may mean, for example, supplying more conditioned air than normal (default setting), as compared to a section supplied with less conditioned air. , More conditioned air may be supplied. Further, supplying less conditioned air may mean, for example, supplying less conditioned air than usual, and using less conditioned air compared to a compartment supplied with more conditioned air. May be supplied. Note that, for example, the temperature of the supplied conditioned air may be controlled instead of controlling the supply amount of the conditioned air. The partition control unit 46, for example, when cooling is performed, so that the conditioned air of a lower temperature from the air conditioner 12 is supplied to the partition with a large heat load indicated by the predicted human flow information, The compartment supply unit 41 corresponding to the compartment may be controlled so that the compartment having a smaller heat load indicated by the predicted human flow information is supplied with the conditioned air of a higher temperature from the air conditioner 12. You may control the division supply part 41 corresponding to a division.

Note that, as described above, it is also possible to calculate the total heat generation amount according to the passersby according to each section, according to the traffic information. For example, when the predicted pedestrian flow information includes an attribute of a passerby, the partition control unit 46 may calculate the total heat generation amount using the attribute. Specifically, the calorific value of a man is usually higher than that of a female, and the total calorific value may be calculated in consideration of this. The partition control unit 46 may perform the same processing as described above according to the total of the calorific values calculated in this way. That is, for example, when cooling is performed, the partition control unit 46 controls the partition supply unit 41 corresponding to the partition so that the supplied cold heat amount of the partition having a large total heat generation amount is large, and the partition control unit 46 generates heat. The compartment supply unit 41 corresponding to the compartment may be controlled so that the supplied cold heat amount of the compartment having a small total amount is small. Even in this case, it is generally considered that the same result as the control using the prediction result of the human flow is obtained.

In addition, the control of the compartment supply unit 41 based on the predicted pedestrian flow information may be, for example, a control in which conditioned air is not supplied to a territory where there is no pedestrian flow. For example, the compartment control unit 46 responds to a compartment indicated by the pedestrian flow information predicted by the pedestrian flow predicting unit 45 so as not to supply air conditioned by the air conditioner 12. The compartment supply unit 41 may be controlled. The section in which the predicted people flow information indicates that there is no person may be a section in which the people flow indicated by the predicted people flow information is 0, or the people flow indicated by the predicted people flow information is predetermined. The number of partitions may be less than the threshold value of. Even in the latter case, if the predetermined threshold value is sufficiently small, it can be considered that there are substantially no people when the flow of people is smaller than the predetermined threshold value. Therefore, it is preferable that the predetermined threshold value is set to a small positive value as compared with the second threshold value or the like. In this way, by not performing air conditioning in a section where there are no people, it is possible to save energy without impairing the comfort of passersby. Even if the conditioned air is not supplied to a certain compartment in this way, the conditioned space is continuous as described above, so the conditioned air may flow in from other compartments. Even if the vehicle passes through a section that is not supplied with conditioned air, it is considered to have little effect on passers-by because it passes for a short period of time.

If the predicted flow information includes the distribution of the passerby attributes, the partition control unit 46 controls the partition supply unit 41 based on the distribution of the passerby attributes. Good. For example, in a section where it is predicted that there will be many males and young people, the temperature may be controlled to be lower than in other sections. On the contrary, in a section where it is predicted that there will be many women and elderly people, the temperature may be controlled to be higher than in other sections.

[Control of air movement between blocks]
Next, control of air movement between blocks will be described.
The block temperature sensor 51 is provided for each block and acquires the temperature of each block. For example, in FIG. 2, the block temperature sensor 51a acquires the temperature of the block 301a. The temperature may be a temperature at any position as long as it is a temperature in the block, but may be a temperature at a position representative of the block, for example, a temperature near the center of the block. Further, the block temperature sensor 51 may acquire, for example, a temperature that is a representative value of measurement results of temperatures at a plurality of positions for a certain block. The temperature acquired by the block temperature sensor 51 may be passed to the inter-block air blowing control unit 59, for example, by wire or wirelessly.

At least a part of the plurality of block temperature sensors 51 and the internal temperature sensor 32 may be the same. For example, the temperature inside the block acquired by any of the block temperature sensors 51 may be used as the internal temperature. In that case, the internal temperature sensor 32 of the air conditioning system 100 and at least one of the block temperature sensors 51 may be physically integrated.

In addition, although FIG. 2 shows the case where the duct 53 is connected to each of the blocks 301a to 301h, if not, that is, if there is a block to which the duct 53 is not connected, the block is connected to that block. Need not be provided with the block temperature sensor 51.

In FIG. 2, the plurality of ducts 53 guide air between the plurality of blocks 301a to 301h. The plurality of air blowers 54 blow air between the blocks via the duct 53. Note that, as shown in FIG. 2, in the present embodiment, the case where the air conditioning system 100 has a plurality of ducts 53 and a plurality of air blowers 54 will be mainly described, but the air conditioning system 100 has one It may have only the duct 53, or may have only one blower 54.

The air in the blocks 301a to 301d on the upper side is respectively sucked through the suction port 52 and is supplied to at least one of the blocks 301e to 301h on the lower side via the air blowing parts 54a to 54d and the duct 53. .. At this time, by operating the dampers 55 to 58, the air in the upper block can be introduced into the desired block in the lower side. For example, the air in the block 301a can be introduced into any one or more blocks 301e to 301h on the lower side by opening and closing the dampers 55e to 55h.

The air in the lower blocks 301e to 301h is respectively sucked through the suction port 52 and is supplied to at least one of the upper blocks 301a to 301d through the air blowing units 54e to 54h and the duct 53. .. At that time, by operating the dampers 55 to 58, the air in the lower block can be introduced into the desired block in the upper side. For example, the air in the block 301e can be introduced into any one or more blocks 301a to 301d on the upper side by opening and closing the dampers 55a to 55d.

In FIG. 2, the air in the lower blocks 301e to 301h can be supplied only to the upper blocks 301a to 301d, and the air in the upper blocks 301a to 301d can be supplied to the lower block 301e. ~301h, but not necessarily. The air in the blocks 301e to 301h on the lower side may be supplied to the other blocks on the lower side, and the air in the blocks 301a to 301d on the upper side may be supplied to the other blocks on the upper side.

In addition, FIG. 2 shows a case where the block of the supply source and the block of the supply destination relating to the supply of air through the duct 53 can be changed by operating the dampers 55 to 58. It doesn't have to be. The block to be connected may be fixed with respect to the duct 53 that guides air between the blocks. Further, in that case, the blowing direction may be fixed or may be switched. For example, it is assumed that the air conditioning system 100 has one duct 53 to which the block of the connection destination is fixed and one blower 54 that blows air through the duct 53. In that case, the air-conditioned space may only be vertically divided into two blocks. That is, the air-conditioned space may not be horizontally divided into blocks. Then, the inter-block air blowing control unit 59 moves the cool air of the lower block to the upper block or warms the upper block to the lower block based on the respective temperatures of the two blocks. The blower unit 54 may be controlled so as to be moved.

The inter-block air blow control unit 59 uses the temperatures acquired by the plurality of block temperature sensors 51 so that the temperature of the block of the air supply source is the temperature of the air conditioner 12 relative to the temperature of the block of the air supply destination. The blower unit 54 is controlled so as to be on the target side in the adjustment direction. As described above, in the case of cooling, the target side in the temperature adjustment direction is the low temperature side, and in the case of heating, the target side in the temperature adjustment direction is the high temperature side. Therefore, when cooling is performed, the relatively cool air of the block of the supply source is supplied to the block of the supply destination, and when heating is performed, the block of the supply source is The relatively warm air of will be supplied to the destination block. In this way, the air can be effectively used and energy saving can be promoted. In the present embodiment, when cooling is performed, at least one of the lower blocks 301e to 301h is a supply source block related to the movement of air between the blocks, and heating is performed. In the case where at least one of the blocks 301a to 301d on the upper side is the block of the supply source relating to the movement of the air between the blocks, the block of the air supply source is on the upper side. The block may be arbitrarily selected without being limited to the block and the block on the lower side.

For example, in FIG. 2, when cooling is being performed, the temperatures of the lower blocks 301e to 301h are usually lower than the temperatures of the upper blocks 301a to 301d, so the lower blocks are The air is supplied to the block on the upper side. The connection relationship between the lower block and the upper block does not matter, but the inter-block air blowing control unit 59 supplies, for example, the air in the lower block having the lowest temperature to the upper block having the lowest temperature. It may be controlled to do so. Further, the inter-block air blow control unit 59 similarly supplies the air of the lower block of the second to fourth lowest temperature to the upper block of the second lowest temperature to the fourth lowest temperature, for example. May be controlled as follows. In these controls, it is assumed that the temperature of the supply source block is lower than the temperature of the supply destination block. If the premise is not satisfied, the inter-block air blowing control unit 59 does not have to move the air vertically.

Further, for example, in FIG. 2, when heating is performed, the temperature of the upper blocks 301a to 301d is usually higher than the temperature of the lower blocks 301e to 301h, so Air will be supplied from this block to the lower block. The connection relationship between the upper block and the lower block does not matter, but the inter-block air blowing control unit 59 supplies, for example, the air in the upper block having the highest temperature to the lower block having the highest temperature. It may be controlled to do so. In addition, the inter-block air blowing control unit 59 similarly supplies the air of the upper block of the second to the fourth highest temperature to the lower block of the second to the fourth highest temperature, for example. May be controlled as follows. In these controls, it is assumed that the temperature of the supply source block is higher than the temperature of the supply destination block. If the premise is not satisfied, the inter-block air blowing control unit 59 does not have to move the air vertically.

In addition, the inter-block air blowing control unit 59 determines that the air of a block having a higher temperature, out of the blocks of the supply source, is indicated by the pedestrian flow information predicted by the pedestrian flow estimation unit 45 to have a low average velocity of the pedestrian flow. The air of the cooler block, which is supplied to the corresponding destination block, is supplied to the destination block corresponding to the section where the predicted human flow information indicates that the average speed of the human flow is high. You may control several ventilation part 54.

The block having a higher temperature may be, for example, a block having the highest temperature, a block having the highest temperature to the Nth block, or a block having a temperature higher than a threshold value. N is an integer of 2 or more. The block having the lower temperature may be, for example, the block having the lowest temperature, the block having the lowest temperature to the Nth block, or the block having the temperature lower than the threshold value.

The section in which the average flow rate of the human flow is shown to be low may be, for example, the section in which the average flow rate of the human flow is shown to be the lowest, and is Mth from the section in which the average flow rate of the human flow is shown to be the lowest. It may be up to a section that is shown to be present, or it may be a section that is shown that the average velocity of the human flow is lower than a threshold value. M is an integer of 2 or more. The section in which the average flow rate of the human flow is high may be, for example, the section in which the average flow rate of the human flow is highest, and is Mth from the section in which the average flow rate of the human flow is highest. It may be up to a section that is shown to be present, or it may be a section that is shown that the average velocity of the human flow is higher than a threshold value.

In addition, when there are a plurality of blocks as supply source candidates, one block may be randomly selected from the plurality of candidate blocks, or each of the plurality of candidate blocks is supplied. It may be the original block. The same applies when there are a plurality of supply destination candidate blocks. Further, in FIG. 2, as described above, the block and the block match, but in other cases, the block corresponding to a certain block may be the block closest to the block.

Pedestrians in sections that are shown to have high average velocities of human flow are moving faster and generate more heat. Therefore, in order to improve the comfort of the passerby, it is preferable to supply the air of lower temperature. On the other hand, the passers-by in the section where the average speed of the pedestrian flow is shown to be moving at a slower speed, and the amount of heat generated is also smaller. Therefore, in order to improve the comfort of the passerby, it is preferable to supply the air of higher temperature.

For example, in FIG. 2, when cooling is being performed, the inter-block air blowing control unit 59 causes the air in the lowest temperature block of the lower blocks 301e to 301h to have the highest average velocity of human flow. It may be controlled so as to be supplied to the upper block corresponding to the section indicated by. In addition, the inter-block air blowing control unit 59 supplies the air of the block having the highest temperature among the blocks 301e to 301h on the lower side to the block on the upper side corresponding to the section in which the average velocity of the human flow is lowest. You may control so that it may be performed. In these controls, it is assumed that the temperature of the supply source block is lower than the temperature of the supply destination block. If the premise is not satisfied, the inter-block air blowing control unit 59 does not have to move the air vertically.

Further, for example, in FIG. 2, when heating is performed, the inter-block air blowing control unit 59 determines that the air of the lowest temperature block among the upper blocks 301a to 301d has the average speed of the human flow. It may be controlled so that it is supplied to the lower block corresponding to the section shown to be the highest. In addition, the inter-block air flow control unit 59 supplies the air of the block having the highest temperature among the blocks 301a to 301d on the upper side to the blocks on the lower side corresponding to the section in which the average velocity of the human flow is shown to be the lowest. You may control so that it may be performed. In these controls, it is assumed that the temperature of the supply source block is higher than the temperature of the supply destination block. If the premise is not satisfied, the inter-block air blowing control unit 59 does not have to move the air vertically.

Further, the inter-block air blowing control unit 59, for example, similarly to the section supply unit 41, regarding the blocks corresponding to the sections in which the people flow information predicted by the people flow predicting unit 45 indicates that there are no people, You may control so that it may not become a supply destination of the movement of air.

In addition, when the block between the supply source and the block of the supply destination to which the air from the block is supplied is determined by the inter-block air blow control unit 59, air is supplied from the supply source block to the supply destination block. The air blower 54 and the dampers 55 to 58 may be controlled so as to be supplied. Specifically, when it is decided to move the air from the block 301e to the block 301a, the inter-block air blow control unit 59 controls to open the damper 55a and close the dampers 55b to 55d, and at the same time, the air blow unit. 54e is controlled to operate. Note that the inter-block air blow control unit 59 controls the air blow unit 54 and the dampers 55 to 58 in such a manner that a control instruction from the inter-block air blow control unit 59 is passed to the air blow unit 54 and the dampers 55 to 58 via wire or wireless. May be done by. Further, the dampers 55 to 58 are automatically opened and closed according to a control instruction.

Next, the operation of the air conditioning system 100 will be described with reference to the flowcharts of FIGS. The flowchart of FIG. 6 is a flowchart showing a process relating to the control of the air volume in the opening part.

(Step S101) The air volume control unit 34 determines whether to perform air volume control in the open section. Then, when the air volume control is performed, the process proceeds to step S102, and when not, the process of step S101 is repeated until it is determined that the air volume control is performed.

The acquisition of the people flow information in step S202 may be update of the people flow information or acquisition of information used for acquiring the people flow information. That is, the people flow information may be finally acquired by repeating the process of step S202. More specifically, when the people flow information is information about the people flow for 30 minutes, the people flow information is updated every predetermined time in step S202, and when 30 minutes have passed, the people flow at that time point is updated. Information may be stored as the final 30 minutes of people flow information. When the attribute information is also acquired, the traffic flow acquisition unit 43 may also acquire the attribute information together with the traffic flow information.

The predetermined period may be, for example, a period corresponding to the traffic information. In the case of the above example, the pedestrian flow prediction unit 45 may determine to perform pedestrian flow prediction every time new pedestrian flow information is acquired, for example, every 30 minutes.

(Step S204) The people flow predicting unit 45 acquires the predicted people flow information by applying the input information including the people flow information acquired by the people flow acquiring unit 43 to the learning device stored in the storage unit 44. ..

Then, when a plurality of sets of the training input information and the training output information are received, the process proceeds to step S302, and otherwise, the process of step S301 is repeated until they are received.

(Step S302) The learning device manufacturing unit 402 manufactures a learning device by machine learning using the training information received in step S301.

(Step S303) The learning device output unit 403 outputs the learning device manufactured in step S302. In this way, a series of processes for manufacturing the learning device is completed.
The order of processing in the flowchart of FIG. 8 is an example, and the order of each step may be changed as long as the same result can be obtained.

Next, operations of the learning device manufacturing apparatus 400 and the air conditioning system 100 according to the present embodiment will be briefly described.
First, in the air-conditioned space, people flow information and attribute information corresponding thereto are acquired. The acquisition may be performed using, for example, the human flow acquisition unit 43. By doing so, a plurality of training information can be prepared. Then, the plurality of prepared training information is input to the learning device manufacturing apparatus 400 to start learning. Then, the training information reception unit 401 receives a plurality of training information, the learning device manufacturing unit 402 performs learning using the plurality of training information to manufacture a learning device, and the manufactured learning device is a learning device. The output unit 403 stores the data in a recording medium (not shown) (steps S301 to S303).

Then, after the learning device is accumulated in the storage unit 44, the air conditioning by the air conditioning system 100 is started. In the air conditioning, the internal temperature and the outdoor temperature are acquired, and when cooling is performed, it is determined whether the outdoor temperature is lower than the internal temperature (steps S101 to S104). Then, when the internal temperature is the same as the outdoor temperature or lower than the outdoor temperature, the wind information acquired by the sensor 31 is used to reduce the movement of the air inside or outside the open portion, or it does not occur. As described above, the supply amount of the supply unit 14 and/or the suction amount of the suction unit 18 are controlled (steps S108 and S109). As a result, it is possible to reduce the flow of conditioned air from the open portion to the outside and the inflow of hot outdoor air into the conditioned space, and it is possible to promote energy saving. Further, when the outdoor temperature is lower than the internal temperature when the cooling is performed, the wind information acquired by the sensor 31 is used to introduce the outside air into the air-conditioned space at the opening portion. The supply amount of the supply unit 14 and/or the suction amount of the suction unit 18 is controlled (steps S105 and S106). As a result, outside air can be introduced into the air-conditioned space, and air conditioning can be performed more efficiently. For example, energy consumption of the heat source device 11 can be suppressed according to the introduction of the outside air, and energy saving can be promoted.

Further, the acquisition of the personal flow information for each section and the acquisition of the attribute information are repeatedly performed (steps S201 and S202). Further, for example, when predicting the people flow information in a new time zone, input information including past people flow information, attribute information corresponding to the people flow information, and attribute information corresponding to the prediction target traffic flow information is input. By applying it to the learning device, the predicted human flow information is acquired (steps S203 and S204). In addition, the predicted human flow information is used to set the temperature for each section, and the supply of conditioned air for each section is controlled (steps S205 and S206). As a result, the section that is expected to have a large number of people will be controlled to have a lower temperature, and the heat generated by passersby in that section can suppress the temperature of that section from rising, and The comfort of passersby can be improved. In addition, a section where it is predicted that the number of people will be small will be controlled to have a higher temperature, and for example, when cooling is being performed, it becomes possible to reduce energy consumption related to that section. ..

Further, the temperature of each block is acquired, and accordingly, useful air, for example, cold air when cooling is performed, is effectively used by moving it between blocks. (Steps S207 to S210). As a result, it is possible to further reduce energy consumption and contribute to energy saving as compared with the case where such useful air is left as it is or exhausted.

As described above, according to the air conditioning system 100 of the present embodiment, it is possible to save energy without impairing the comfort of people in the air conditioned space. Specifically, energy saving can be achieved by controlling the air flow in the open portion. Specifically, by suppressing the movement of air inside and outside the open portion, it is possible to suppress the leakage of conditioned air and the inflow of uncomfortable air, and it is possible to reduce the energy consumption related to air conditioning. In addition, since it is not necessary to provide an air curtain or the like in the open portion, energy can be saved without giving discomfort to passersby. Further, when there is comfortable air outdoors, by introducing the outside air into the air-conditioned space, it is possible to suppress the operation of the heat source device 11 and the air conditioner 12, and to promote further energy saving. ..

In addition, by performing air conditioning control for each section based on the prediction of pedestrian flow, for example, it is possible to make the cooling more effective in a section where it is predicted that there will be a large number of pedestrian traffic, thus improving the comfort of passersby. Will be able to Further, for example, in a section where it is predicted that the number of people will be small, energy saving can be achieved by weakening the effect of cooling. Also, if the air conditioning is controlled according to the current sensing result of the pedestrian flow, there is a time lag between the time when the air conditioning is controlled and the time when the conditioned air is actually provided to the conditioned space. Although it may decrease, it is possible to prevent such a time lag by performing control based on the predicted flow information, and it is possible to further improve comfort.

Further, by obtaining the temperature of each block and appropriately moving the air between the blocks, the conditioned air can be used more efficiently, and energy saving can be promoted. For example, at the time of cooling, 27°C air near the center of an underground mall may be air with low comfort near the center, but may be comfortable air near an open area where temperature tends to be high. .. Therefore, by moving the 27° C. air to the vicinity of the open portion, the air can be effectively used, and energy saving can be further promoted.

In addition, the inventors of the present application implement all of the control of the air volume in the open portion, the air conditioning control for each section based on the pedestrian flow prediction, and the air movement control between blocks in an underground mall that is a large-scale air-conditioned space. An experiment was conducted. As a result of the experiment, it was confirmed that the control by the air conditioning system 100 of the present embodiment can reduce the air conditioning energy consumption by about 40%. In this way, the effectiveness of the air conditioning system 100 according to the present embodiment is actually confirmed in this way.

Further, in the present embodiment, as shown in FIG. 1, the case where the air sucked from the fixed suction port 16 is returned or exhausted has been described, but it may not be so. For example, suction ports may be provided on the upper side and the lower side of the air-conditioned space 200, respectively. Then, during cooling, for example, the air sucked from the lower suction port may be returned and reused without being discharged, and the air sucked from the upper suction port may be discharged without returning. Conversely, during heating, for example, the air sucked from the upper suction port may be returned and reused without being exhausted, and the air sucked from the lower suction port may be discharged without returning. ..

Further, in the present embodiment, a case has been mainly described where the air conditioning system 100 performs all of air volume control in the open portion, air conditioning control for each section based on human flow prediction, and air movement control between blocks. It doesn't have to be. The air conditioning system 100 may perform any one or more of these three controls.

For example, when the air conditioning system 100 does not control the air volume in the open section, the air conditioning system 100 does not have to include the sensor 31, the supply section 14, the suction section 18, and the air volume control section 34. Even in that case, the air conditioning system 100 may additionally include a suction unit for sucking air from the air-conditioned space and a supply unit that supplies the air-conditioned air to the air-conditioned space.

Further, for example, when the air conditioning system 100 does not perform the air conditioning control for each section based on the human flow prediction, and when the predicted human flow information is not used in the movement control of the air between the blocks, the air conditioning system 100 Need not include the compartment supply unit 41, the laser range finder 42, the pedestrian flow acquisition unit 43, the storage unit 44, the pedestrian flow prediction unit 45, and the like.

Further, for example, when the air conditioning system 100 does not control the movement of air between the blocks, the air conditioning system 100 includes the block temperature sensor 51, the duct 53, the air blower 54, the dampers 55 to 58, and the air blow controller between the blocks. 59 may not be provided.

It may be provided with a partition control unit that controls a plurality of partition supply units based on the human flow information.

For example, in an air-conditioned space divided into blocks, an air-conditioning system that controls the movement of air between blocks has an air conditioner that adjusts the temperature of the air and a plurality of blocks that are provided for each block that obtain the temperature of the block. Using the block temperature sensor, one or more ducts that guide air between the plurality of blocks, one or more air blowers that blow air through the ducts, and the temperatures acquired by the plurality of block temperature sensors, An inter-block air blow control unit that controls one or more air blow units so that the temperature of the block that is the supply source of is on the target side in the direction of temperature adjustment by the air conditioner with respect to the temperature of the block that is the destination of air supply. It may be provided.
