[0012] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0013] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In addition, in each drawing, the same reference numerals are used for substantially the same configuration, and duplicated explanations may be omitted or simplified.

[0014] (Embodiment) [composition] First, the configuration of the private booth according to the embodiment will be described. FIG. 1 is a diagram showing a schematic configuration of the private booth according to the embodiment. The private booth 200 is a work booth having a work space therein. Therefore, the private booth 200 can be said to partition the work space. The work space is a space for personal work, and is a space of a volume necessary for one user to perform intellectual work. In the work space, the user performs intellectual work such as business or study. The private booth 200 has a partition wall 20 for partitioning the work space. The partition wall 20 is composed of a ceiling partition wall (partition wall on the upper side of the paper) having a ceiling surface, a floor partition wall (partition wall on the lower side of the paper) having a floor surface, and a side wall (partition wall on the left and right sides of the paper) having a side wall surface connecting the ceiling surface and the floor surface. The partition wall 20 separates the work space from the outside space, thereby partitioning the work space. The ceiling partition wall is provided with an upper outlet 21 for supplying air from the ceiling surface toward the work space (downward toward the floor surface). The floor partition is also provided with a lower outlet 22 for supplying air from the floor surface toward the work space (upward toward the ceiling surface).

[0015] The private booth 200 also has a private booth air conditioning system 10. The private booth air conditioning system 10 includes an air conditioner 11, a blower 12, and a control device 13. The air conditioner 11 and the blower 12 are connected to an upper outlet 21 and a lower outlet 22, and control the air supplied from the upper outlet 21 and the lower outlet 22.

[0016] Specifically, the air conditioner 11 is a device that adjusts the temperature of air supplied from each of the upper outlet 21 and the lower outlet 22. The air conditioner 11 is capable of heating control to adjust the air to a temperature above room temperature and cooling control to adjust the air to a temperature below room temperature. Note that, although the air conditioner 11 has been described as a device that adjusts the temperature of the air to be supplied, it also has a minimum blowing function for moving the adjusted air to the upper outlet 21 and the lower outlet 22.

[0017] Moreover, blower 12 is a device that adjusts the amount of air supplied from each of upper outlet 21 and lower outlet 22. Blower 12 has a rotating fan, and can control the amount of air movement, i.e., the amount of air supply, by the amount of rotation (number of rotations per unit time).

[0018] The air conditioner 11 and the blower 12 can control the temperature and supply amount of air individually for each of the upper outlet 21 and the lower outlet 22. In other words, the air conditioner 11 and the blower 12 can control the temperature and supply amount of air at the upper outlet 21 to a first temperature and a first supply amount, and control the temperature and supply amount of air at the lower outlet 22 to a second temperature and a second supply amount. The first temperature and the second temperature are, for example, different temperatures, but it is also possible for the first temperature to be lower than room temperature and the second temperature to be higher than room temperature. In other words, the air conditioner 11 can use heating control and cooling control separately for each of the upper outlet 21 and the lower outlet 22.

[0019] Here, each of the upper air outlet 21 and the lower air outlet 22 has a plurality of partial air outlets in a direction intersecting the air outlet direction. That is, the position to which the air is directed in the working space can be controlled by using which partial air outlet (from which partial air outlet the air is supplied). For example, the air conditioner 11 and the blower 12 can supply air toward the position of the user's head, toward the position of the user's arms, or toward the position of the user's hands in the left-right direction of the paper in FIG. 1. In this case, the air conditioner 11 and the blower 12 need to use the partial air outlets differently, such as supplying air from a partial air outlet corresponding to the position of the user's head, supplying air from a partial air outlet corresponding to the position of the user's cups, or supplying air from a partial air outlet corresponding to the position of the user's hands. The air conditioner 11 and the blower 12 have a function of using the partial air outlets differently, that is, a function of changing which partial air outlet is used to supply air to the working space.

[0020] The control device 13 is a device that generates an airflow that assists a user in performing intellectual work by controlling the air conditioner 11 and the blower 12. The control device 13 is realized by a computer connected to the air conditioner 11 and the blower 12. The computer controls the air conditioner 11 and the blower 12 by executing a predetermined program using a processor and a memory. Specifically, the control device 13 has the functional configuration shown in FIG. 2. FIG. 2 is a block diagram showing the functional configuration of the control device according to the embodiment. As shown in FIG. 2, the control device 13 has a control unit 13a, an acquisition unit 13b, and a concentration level estimation unit 13c.

[0021] The control unit 13a controls the air conditioner 11 and the blower 12. For example, the control unit 13a transmits to the air conditioner 11 a control signal indicating the temperature of the conditioned air and a control signal specifying the partial outlet used to supply the air. The air conditioner 11 then performs heating control and cooling control so that the conditioned air has a temperature indicated in the control signal, and moves the conditioned air so that it is supplied from the partial outlet specified in the control signal. The control unit 13a also transmits to the blower 12, for example, a control signal indicating the supply amount of the conditioned air and a control signal specifying the partial outlet used to supply the air. The blower 12 then rotates the fan so that the supply amount of the conditioned air has the amount indicated in the control signal, and moves the conditioned air so that it is supplied from the partial outlet specified in the control signal.

[0022] The acquisition unit 13b acquires the work start timing and the work end timing of the user of the private booth 200. The acquisition unit 13b acquires the work start timing and the work end timing based on the user's input from, for example, a user interface (not shown) installed in the private booth 200 for inputting the work start and work end times. In particular, the user interface for inputting the work start timing may be a simple one such as a work start button. On the other hand, the user interface for inputting the work end timing is preferably configured to be able to acquire the work end timing input in advance, since the work end timing is used to control the air conditioner 11 and the blower 12 before the work end timing, but it can also be realized by a simple one such as a work end button as described above. This point will be described later.

[0023] The acquisition unit 13b may acquire the work start timing and work end timing input in advance from an external schedule management server, or may estimate and acquire the work start timing and work end timing by grasping the user's condition using a sensor installed in the private booth 200 (such as a pressure sensor for detecting whether the user is seated, a human presence sensor for detecting whether the user is present, or a camera for image analysis).

[0024] The concentration level estimation unit 13c estimates the concentration level of a user who is using the private booth 200. The concentration level estimation unit 13c estimates the concentration level of the user based on, for example, detection results acquired from a sensor installed in the private booth 200 or a wearable sensor worn by the user. The combination of sensors and algorithms used in estimating the concentration level of the user may be based on any existing technology. Here, any sensor may be used as long as it is possible to estimate the concentration level of the user, and the concentration level of the user may be estimated in any way from the detection results.

[0025] Moreover, the concentration level estimation unit 13c is not an essential component. It is generally said that a person can only maintain a concentration level for a sustained period of about several minutes to several tens of minutes. Therefore, based on such a general tendency, it may be predicted that the concentration level will fall below a predetermined value when a predetermined period corresponding to the sustained period has passed from the timing of starting the work or the timing when a predetermined period has passed since the timing of starting the work. In such a case, it is sufficient to only manage the elapsed time without a sensor for direct concentration level estimation and a processing unit for estimation (concentration level estimation unit 13c). This point will also be described later in the explanation of an operation example of the private booth air conditioning system 10.

[0026] [Example] Next, an operation example of the private booth air conditioning system 10 will be described. Fig. 3 is a flow chart of an operation example of the private booth air conditioning system according to the embodiment. Figs. 4 to 7 are diagrams for explaining the state of the private booth in the operation example.

[0027] First, the acquisition unit 13b acquires the timing of the user's work start and end (step S11). The control unit 13a determines whether or not it is time to start work (step S12), and if it is not time to start work (No in step S12), repeats step S12 until it is time to start work. Then, if it is time to start work (Yes in step S12), control of the air conditioner 11 and the blower 12 is started (step S13). After that, until the processing is completed, the control unit 13a continuously controls the air conditioner 11 and the blower 12 while switching the control mode. In addition, although not shown, the concentration level estimation unit 13c starts estimating the concentration level of the user in accordance with the start of work. The concentration level estimation is also continuously performed in the same manner as the control of the air conditioner 11 and the blower 12.

[0028] First, the control unit 13a controls the air conditioner 11 and the blower 12 to supply air at a first strength (first supply amount) during a period (first period) from the timing of starting work to the passage of a first time (step S14). FIG. 4 shows the state of the private booth 200 during the first period. In FIG. 4, the airflows supplied to the work space from the upper air outlet 21 and the lower air outlet 22 are indicated by white arrows. The same is true for FIGS. 5 to 6. The vertical size of the arrow indicates the amount of air being supplied (the larger the arrow, the greater the supply amount).

[0029] As shown in FIG. 4, in the first period, air is supplied at a relatively large supply rate. For example, in the first period, air is supplied at a supply rate of 1 m / s. Here, the adjustment of the supply rate by the blower 12 mainly works, and temperature adjustment by the air conditioner 11 is unnecessary or only maintains the room temperature. In addition, when the room temperature or the outside air temperature is high, the temperature may be slightly lower than the room temperature. In the first period, air is supplied from all the partial air outlets. By supplying air from above and below, the user in the work space can lower the perceived temperature, and refresh the mind and body so that it is easier to start working. The first period is a short period of several minutes, for example, 1 minute, 2 minutes, 3 minutes, 4 minutes, or 5 minutes. Therefore, the first time is set to a time equivalent to the length of the first period.

[0030] Returning to Fig. 3, the control unit 13a judges whether or not it is the second period after the first time has elapsed (step S15), and if it is not the second period (No in step S15), the process returns to step S14 and continues to supply air at the first strength until the first time has elapsed. Then, if it is the second period (Yes in step S15), the control unit 13a controls the air conditioner 11 and the blower 12 to supply air at the second strength (second supply amount) (step S16). Fig. 5 shows the state of the private booth 200 in the second period.

[0031] As shown in FIG. 5, in the second period, air is supplied at a relatively small supply rate. Here, the temperature is adjusted mainly by the air conditioner 11, and the supply rate is adjusted by the blower 12 to the minimum necessary. The supply rate of air in the second period is the supply rate for maintaining the room temperature of the work space, and depends on the size of the work space. Therefore, the minimum supply rate required for each temperature is checked in advance, and the supply rate is determined by referring to the result. The supply rate here is smaller than the first supply rate, and the third and fourth supply rates described later. In other words, the supply rate here is the smallest supply rate in the entire period. For example, in the second period, air is supplied at a supply rate with a wind speed of 0.1 m / s.

[0032] Here, for example, the control unit 13a maintains the work space at a temperature suitable for work by supplying air at or below room temperature from the upper outlet and air at or above room temperature from the lower outlet. The user's head is cooled with air at which the user does not feel the airflow (no airflow stimulation), while the user's feet are warmed with air at which the user does not feel the airflow (no airflow stimulation), and as a whole, a temperature suitable for the user's work is maintained. The temperature suitable for the user's work may be set based on the past usage history of each user, or may be adjusted to a temperature generally considered to be suitable, for example, a PMV of -0.5 to 0.5, more preferably a PMV of -0.2 to 0.2, and even more preferably a PMV of 0.

[0033] In the second period, air is supplied from all the partial air outlets, and a relatively small supply volume is maintained to minimize airflow stimulation. This makes it possible to maintain a temperature sensation suitable for work while suppressing disruption of concentration due to airflow stimulation and disruption of concentration due to the auditory stimulation of wind noise caused by airflow.

[0034] Returning to Fig. 3, the control unit 13a determines whether or not a predetermined condition related to the concentration level of the user is satisfied within the second period (step S17), and if the predetermined condition is not satisfied (No in step S17), skips the following step S18. On the other hand, if the predetermined condition is satisfied (Yes in step S17), the control unit 13a controls the air conditioner 11 and the blower 12 to supply air at a third strength (third supply amount) (step S18). Fig. 6 shows the state of the private booth 200 at the time when the predetermined condition related to the concentration level of the user is satisfied during the second period.

[0035] As shown in FIG. 6, even in the second period, when a predetermined condition related to the user's concentration is satisfied, a relatively large amount of air is supplied from the upper air outlet 21 and the partial air outlets of the lower air outlet 22 corresponding to the position of the user's hands. For example, when a predetermined condition is satisfied, air is supplied at a wind speed of 1 m / s. Such air acts as an airflow stimulus and can encourage the user to relax their attention slightly (also called micro-refreshment). Therefore, the attention of the user who was only directed to the intellectual work is temporarily directed to the airflow stimulus, and when the user returns to the intellectual work, the user's concentration improves. Here, the partial air outlets corresponding to the position of the user's hands are used. For example, since the user's head and arms may be difficult to notice because of the presence of hair and clothing on the skin, it is necessary to supply a larger amount of air. From this perspective, it can be said that the position of the hands is suitable because it is easy to notice the airflow stimulus if the strength is to a certain extent.

[0036] Here, the main function is to adjust the supply amount by the blower 12, and temperature adjustment by the air conditioner 11 is unnecessary or is merely to maintain the room temperature. However, since the effect of micro-refreshing can also be generated by stimulating a hot / cold sensation, for example, the control unit 13a may control the air conditioner 11 as well as the blower 12 to supply air of a third strength that is lower than the room temperature.

[0037] The supply of air at the third strength is carried out for, for example, several tens of seconds to several minutes. More specifically, the supply of air at the third strength is carried out for any length of time between 20 seconds and 1 minute.

[0038] The predetermined condition may be, for example, that the estimated concentration level falls below a predetermined value. The predetermined value differs depending on the user, but as an example, the relationship between the work efficiency and the concentration level during past intellectual work may be examined, and the concentration level at the timing when the work efficiency starts to decline may be used.

[0039] Alternatively, since a predetermined period that results in such a predetermined value of concentration can be investigated, the passage of a predetermined period may be used as the predetermined condition. Since a decrease in concentration may occur multiple times, the concentration can be restored under realistic conditions by satisfying the predetermined condition each time a predetermined period passes (both when a predetermined period has passed since the start of work and when another predetermined period has passed after the predetermined period has passed). In addition, the predetermined period can be gradually shortened according to the time that has passed since the start of work. For example, the predetermined period may be 15 minutes from the start of work until 30 minutes, 10 minutes from the start of work until 60 minutes, and 5 minutes after 60 minutes from the start of work.

[0040] 3, the control unit 13a determines whether the second period has ended and the third period has begun (step S19), and if it is not the third period (No in step S19), the process returns to step S16 and continues to supply air at the second strength until the second period ends. Then, if it is the third period (Yes in step S19), the control unit 13a controls the air conditioner 11 and the blower 12 to supply air at a fourth strength (fourth supply amount) (step S20).

[0041] The third period may be the period from a timing calculated backwards from the timing of the work end to the timing of the work end, or may be the period from after the timing of the input of the work end to the timing of the actual work end. Specifically, the former is a case where the input of the work end timing indicates the timing at which the user ends use of the private booth 200. And the latter is a case where the input of the work end timing indicates a timing that assumes the third period and is prior to the timing at which the user ends use of the private booth 200.

[0042] In this embodiment, a period (also called a relaxation period) is provided in which a relaxing effect is imparted by supplying air before the user finishes using the private booth 200 in the third period. Therefore, the timing of the end of the work is the end of the relaxation period. The timing of the end of the work acquired from the user may indicate the start of the relaxation period or the end of the relaxation period. When the timing of the end of the work acquired from the user indicates the start of the relaxation period, input of the timing of the end of the work is accepted by a simple user interface such as an end of work button, and it is determined that the third period begins from the accepted timing, and the work ends after the second time period of the relaxation period. On the other hand, when the timing of the end of the work acquired from the user indicates the end of the relaxation period, it is necessary to transition to the relaxation period at a timing that is the second time period back from that timing, so it is determined that the third period begins from that timing. The second time period is several tens of seconds to several minutes. More specifically, the second time period is any length of several tens of seconds to three minutes.

[0043] FIG. 7 shows the state of the private booth 200 in the third period. As shown in FIG. 7, in the third period, air is supplied at a relatively large supply amount. Here, the adjustment of the supply amount by the blower 12 mainly works, and the adjustment of the temperature by the air conditioner 11 is unnecessary or is only enough to maintain the room temperature. In addition, when the room temperature or the outside air temperature is high, the temperature may be slightly lower than the room temperature. In the third period, air is supplied from the partial outlet in front of the user. More specifically, air is supplied from the partial outlets at positions facing each other of the upper outlet 21 and the lower outlet 22, where the air supplied from each of the upper outlet 21 and the lower outlet 22 collides in front of the user. In addition, in the third period, air is supplied with a strength that causes the supplied air to collide at least at the height of the upper body of the user. In this way, as shown in the figure, an air flow is generated in which the colliding air from above and below changes its traveling direction and moves toward the user. For example, in the third period, air is supplied at a supply rate of 0.1 m / s.

[0044] Here, airflows from above and below are combined to generate an airflow in a direction intersecting the vertical direction, i.e., a horizontal airflow. Such a collision airflow is prone to turbulence, and the direction of travel changes horizontally at multiple heights, not just one height, so that an airflow that moves toward the user in a plane (hereinafter also referred to as a plane airflow) can be generated. Such a plane airflow generates airflow stimulation over a wide area of ​​the user's front side (from the collision position of the airflows from above and below), and therefore has the advantage of easily achieving a whole-body relaxation effect. In the third period, the control unit 13a may adjust the amount and temperature of air supply that easily generates a plane airflow. In order to obtain a plane airflow during the relaxation period, a dedicated air outlet may be provided separately on the front side of the user. However, as described above, by using the upper air outlet 21 and the lower air outlet 22 that are originally provided on the top and bottom, the configuration of the private booth 200 can be simplified, which is advantageous in terms of cost and the like.

[0045] 3, the control unit 13a determines whether or not it is time to end the work (step S21), and if it is not time to end the work (No in step S21), the process returns to step S20 and continues to supply air at the fourth strength until the end of the third period. Then, if it is time to end the work (Yes in step S21), the process ends.

[0046] As described above, in this embodiment, the user using the private booth 200 is encouraged to switch his / her mind and body during the first period to easily transition to intellectual work, and during the second period, while maintaining a sense of warmth and cold so that the user can easily continue the intellectual work, micro-refreshment is performed when a predetermined condition that reduces the level of concentration is met to restore the level of concentration again, and a relaxation period is provided at the end of the work to suppress discomfort during the work, making it difficult for subsequent activities to be hindered. Thus, the private booth air-conditioning system 10 etc. can support the user's intellectual work.

[0047] [Effects, etc.] Inventions derived from the disclosure of this specification are, for example, the following inventions. Hereinafter, the inventions derived from the disclosure of this specification will be described together with the effects and the like obtained by the inventions.

[0048] Invention 1 is an air conditioning system 10 for a private booth that partitions a work space for individual work, the system supplying air to the work space from an upper air outlet 21 provided on a ceiling surface of the private booth 200 and having a plurality of partial air outlets in a direction intersecting the air outlet direction, and a lower air outlet 22 provided on a floor surface of the private booth 200 and having a plurality of partial air outlets in a direction intersecting the air outlet direction, the system comprising: an air conditioner 11 that adjusts the temperature of the air supplied from each of the upper air outlet 21 and the lower air outlet 22; The apparatus includes a blower 12 that adjusts the amount of air supplied from each of the upper air outlet 21 and the lower air outlet 22, and a control device 13.
