[0003] Prior Art Documents Patent Documents Patent Document 1: Japanese Patent Laid-Open Gazette No. 2019-143631 Summary of the Invention -Technical Problem to be Solved by the Invention-

[0004] In the case of reproducing the natural wind at a distance using the air supply device of Patent Document 1, for example, when a gust of wind blows at a distance, a very strong wind is instantaneously blown from the air supply device. In this case, the paper on the table may be blown away, or the hair of a person may be messed up by the wind of the air supply device. Thus, if a strong wind is reproduced indoors, depending on the different conditions of the person who comes into contact with the wind of the air supply device, discomfort may sometimes be felt. In addition, for example, when a very weak breeze close to calm blows at a distance, a very weak wind is blown from the air supply device. In this case, sometimes the person who originally came into contact with the wind of the air supply device suddenly feels no wind, and thus suspects that the air supply device has malfunctioned or the like and feels uneasy or strange.

[0005] An object of the present disclosure is to reproduce the wind in a natural environment without impairing comfort. -Technical Solution for Solving the Technical Problem-

[0006] In a first aspect, an air volume adjustment device A is targeted. The air volume adjustment device A adjusts the air volume of a fan 30 that reproduces the wind at a distance in an object space S. The air volume adjustment device A includes a control unit C that outputs a control value of the fan 30. The control unit C acquires wind data regarding the wind obtained at the distance, and outputs a control value different from the control value corresponding to the acquired wind data.

[0007] In the first aspect, the control unit C outputs a control value of the fan 30 that is different from the control value corresponding to the acquired wind data. Thereby, the wind obtained by adjusting the wind at a distance is blown out from the fan 30. Therefore, the wind in a natural environment can be reproduced without impairing the comfort of the person in the object space S.

[0008] The second aspect is that, based on the first aspect, the control unit C generates processed data obtained by processing the wind data, and determines the control value to be output based on the processed data.

[0009] In the second aspect, the control unit C is used to generate processed data obtained by processing the wind data, and determines the control value to be output based on the processed data. Thereby, it is possible to blow out wind after adjusting the wind in the distance from the fan 30.

[0010] The third aspect is that, based on the first aspect, the control unit C determines the control value corresponding to the wind data, corrects the determined control value, and determines the corrected value as the control value to be output.

[0011] In the third aspect, the control unit C is used to determine the control value corresponding to the wind data and correct the determined control value. The control unit C determines the corrected value as the control value to be output. Thereby, the fan 30 can blow out wind after adjusting the wind in the distance.

[0012] The fourth aspect is that, based on any one of the first aspect to the third aspect, the control unit C outputs the control value showing the same tendency as the increase or decrease tendency of the wind speed in the wind data.

[0013] In the fourth aspect, the control value output by the control unit C shows the same tendency as the increase or decrease tendency of the wind speed in the wind data. Therefore, it is possible to reproduce in the target space S wind with fluctuations the same as those of the wind in the distance.

[0014] The fifth aspect is that, based on the fourth aspect, the control unit C outputs the control value such that the average wind speed of the air blown out from the fan 30 reaches the average wind speed arbitrarily set by the user.

[0015] In the fifth aspect, the control value output by the control unit C is the control value such that the average wind speed of the air blown out from the fan 30 reaches the average wind speed arbitrarily set by the user. Thereby, wind with an intensity freely set by the user and fluctuations the same as those of the wind in the distance is reproduced in the target space S.

[0016] The sixth aspect is that, based on the fourth aspect, the control unit C multiplies the data based on the wind data by a specified value.

[0017] In the sixth aspect, the control unit C is used to multiply the data based on the wind data by a specified value. Thereby, the control value of the fan 30 is adjusted, so the intensity of the wind blown out from the fan 30 is adjusted, and wind with a changed intensity relative to the wind in the distance and fluctuations the same as those of the wind in the distance is reproduced in the target space S.

[0018] The seventh aspect is that, based on the fourth aspect, the control unit C defines a function for data operation based on the wind data.

[0019] In the seventh aspect, a function for data operation based on the wind data is defined by the control unit C. Thereby, the control value of the fan 30 is adjusted, so that the intensity of the wind blown from the fan 30 is adjusted, and the wind with a changed intensity relative to the wind in the distance and the same fluctuation as the wind in the distance is reproduced in the target space S.

[0020] The eighth aspect is that, based on any one of the first to seventh aspects, when the state where the wind speed value of the wind data exceeds the upper limit value of the rotation speed of the fan 30 continues for a predetermined time or more, the control unit C outputs a control value different from the control value corresponding to the obtained wind data.

[0021] If the state where the wind speed value of the obtained wind data exceeds the upper limit value of the rotation speed of the fan 30 continues for a certain period of time, the wind speed of the air blown from the fan 30 will be constant at the upper limit value of the rotation speed of the fan 30, and the fluctuation of the wind in the distance will not be reproduced. Thus, in the eighth aspect, in this state, by outputting a control value different from the control value corresponding to the obtained wind data, the fluctuation of the wind in the distance can be reproduced in the target space S.

[0022] The ninth aspect is that, based on any one of the first to eighth aspects, when the state where the wind speed value of the wind data exceeds the upper limit wind speed arbitrarily set by the user in advance continues for a predetermined time or more, the control unit C outputs a control value different from the control value corresponding to the obtained wind data.

[0023] If the state where the wind speed value of the obtained wind data exceeds the upper limit wind speed arbitrarily set by the user in advance continues for a certain period of time, the wind speed of the air blown from the fan 30 will be constant at the set upper limit wind speed, and the fluctuation of the wind in the distance will not be reproduced. Thus, in the ninth aspect, in this state, by outputting a control value different from the control value corresponding to the obtained wind data, the fluctuation of the wind in the distance can be reproduced in the target space S.

[0024] The tenth aspect is that, based on any one of the first to ninth aspects, when the state where the wind speed value of the wind data is equal to or less than a predetermined reference value continues for a predetermined time or more, the data amplification based on the wind data is performed.

[0025] When the wind speed value of the acquired wind data is below a specified reference value, a very weak wind is blowing in the distance. If such a weak wind persists for a certain period of time, a person in the object space S will not be able to feel the wind because the wind blown from the fan 30 is very weak. Thus, in the tenth aspect, in such a state, by amplifying the data based on the wind data by the control unit C, a person in the object space S can continuously receive the reproduction of the wind in the distance.

[0026] The eleventh aspect is that, based on any one of the first aspect to the tenth aspect, the air volume adjustment device further includes a storage unit 18 that pre-stores substitute data about wind different from the wind data, and when the state where the wind speed value of the wind data is below a specified reference value persists for more than a specified time, the control unit C determines the control value to be output based on the substitute data.

[0027] When the wind speed value of the acquired wind data is below a specified reference value, a very weak wind is blowing in the distance. If such a weak wind persists for a certain period of time, a person in the object space S will not be able to feel the wind because the wind blown from the fan 30 is very weak. Thus, in the eleventh aspect, in such a state, by having the control unit C determine the control value to be output based on the substitute data, a person in the object space S can continuously receive the reproduction of the wind in the distance.

[0028] The twelfth aspect is that, based on any one of the first aspect to the eleventh aspect, the control unit C outputs a signal according to the data based on the wind data, and the signal is used to generate a sound simulating a natural environment.

[0029] In the twelfth aspect, since the control unit C outputs a signal corresponding to the data based on the wind data and used to generate a sound simulating a natural environment, a sound simulating a natural environment is emitted from the sound generating device.

[0030] The thirteenth aspect relates to a ventilation system, and the ventilation system includes the air volume adjustment device according to any one of the first aspect to the twelfth aspect.

[0031] In the thirteenth aspect, a ventilation system can be provided that can reproduce the wind in a natural environment without impairing the comfort of a person in the object space S. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that the present disclosure is not limited to the embodiments shown below, and various changes can be made without departing from the technical idea of the present disclosure. Each drawing is used to conceptually illustrate the present disclosure, and therefore, for easy understanding, the dimensions, ratios, or quantities are sometimes exaggerated or simplified as needed.

[0034] 《First Embodiment》 Refer to Figures 1 to 15 and describe the air supply system 1 of the first embodiment.

[0035] (1) Air supply system The air supply system 1 is a system that reproduces the natural wind in the distance in the target space S. As Figure 1 shown, the air supply system 1 includes an air supply device 10 and a sensor unit 50. The air supply device 10 and the sensor unit 50 are arranged at a distance from each other.

[0036] The air supply device 10 is arranged, for example, in an indoor space (target space S) such as an office or an event space in a building. The air supply device 10 blows out a wind that simulates the natural wind in the distance into the target space S. Details of the air supply device 10 will be described later.

[0037] The sensor unit 50 is arranged outdoors at a distance. The sensor unit 50 has a sensor 51 and a transmission unit 52.

[0038] The sensor unit 50 includes a wind speed sensor as the sensor 51. The wind speed sensor measures the speed of the wind (natural wind) blowing in the outdoor natural environment where the sensor unit 50 is provided. In addition to the wind speed sensor, the sensor unit 50 may further include other sensors as the sensor 51. For example, the sensor 51 may further include a temperature sensor that measures the temperature outdoors where the sensor unit 50 is provided.

[0039] The transmission unit 52 is communicably connected to the air supply device 10 via a communication line 45 such as the Internet. The transmission unit 52 transmits data about the wind in the distance (hereinafter referred to as wind data) including the detection values of the sensor 51 to the air supply device 10 via the communication line 45 at regular intervals. In the wind data, for example, data such as time series data of wind speed, average wind speed within a specified period, variation pattern of wind speed within a specified period, and average temperature within a specified period are included.

[0040] In the sensor unit 50 of the present embodiment, the wind speed is measured once every 5 seconds by the wind speed sensor. When the sensor unit 50 obtains six wind speed values, the six obtained wind speed values (equivalent to wind speed data for a 30 - second period) are sent as a set of time series data of wind speed (hereinafter referred to as wind speed data) from the transmission unit 52 to the air supply device 10. The transmission unit 52 sends the average wind speed value of a set of wind speed data together with the set of wind speed data. That is to say, in the present embodiment, the wind speed data and the average wind speed value are sent as wind data from the sensor unit 50 to the air supply device 10 every 30 seconds.

[0041] It should be noted that the number of wind speed values included in a set is only an example. In addition, the wind data sent from the sensor unit 50 only needs to be data about the wind for several tens of seconds, and does not necessarily have to be data for a 30 - second period.

[0042] (2) Air supply device The air supply device 10 is a device that reproduces the wind in the distance where the sensor unit 50 is provided in the target space S. As Figure 2 shown, the air supply device 10 has a main body portion 15 including an air supply fan 30, a receiving portion 17, a storage portion 18, a control portion 40, and an input portion 19. The air supply device 10 of the present embodiment can execute multiple operation modes.

[0043] (2 - 1) Main body portion As Figure 3As shown, the main body 15 is formed in the shape of a rectangular parallelepiped with a relatively short depth in the front-rear direction. The width of the main body 15 in the left-right direction and the height in the up-down direction are approximately 1.6 m respectively. It should be noted that the "up", "down", "left", "right", "front", and "rear" used in the description of the main body 15 refer to Figure 3 the directions shown (the directions when observing the main body 15 from the front).

[0044] Sixteen air supply fans 30 are provided on the main body 15. Each air supply fan 30 blows air into the target space S. The air supply fan 30 corresponds to the fan 30 of the present disclosure. On the main body 15, the sixteen air supply fans 30 are arranged in a matrix of four in the left-right direction and four in the up-down direction.

[0045] Each air supply fan 30 is an axial flow blower including an impeller 31 and a shroud 32. The impeller 31 is a so-called propeller fan. In each air supply fan 30, the shroud 32 is arranged so as to surround the periphery of the impeller 31. A fan motor (not shown) for driving the impeller 31 is provided on each air supply fan 30. The impeller 31 is mounted on the output shaft of the fan motor.

[0046] On the main body 15, the sixteen air supply fans 30 face the front surface of the main body 15. The front surface of the main body 15 constitutes a blowing area 16 from which the air blown out from each air supply fan 30 is blown. In the air supply device 10 of the present embodiment, the blowing area 16 is a square plane with a width of 1.6 m in the left-right direction and a height of 1.6 m in the up-down direction.

[0047] (2 - 2) Receiving unit The receiving unit 17 is communicably connected to the transmitting unit 52 of the sensor unit 50 via the communication line 45. The receiving unit 17 receives the wind data transmitted from the transmitting unit 52 in real time.

[0048] The receiving unit 17 receives the wind data within the first specified period in the past. The first specified period in the present embodiment is 30 seconds. The receiving unit 17 receives the wind data (a set of wind speed data and average wind speed values) within the 30 - second period immediately before the data reception time. The receiving unit 17 may also receive the wind data detected by the sensor 51 not long ago instead of the wind data detected within the period immediately before the data reception time.

[0049] (2 - 3) Storage unit The storage unit 18 stores the wind data received by the receiving unit 17. The storage unit 18 includes at least one of an HDD (Hard Disk Drive), a RAM (Random Access Memory), and an SSD (Solid State Drive).

[0050] (2-4) Control Unit The control unit 40 includes a microcomputer and a storage device. The storage device stores software for operating the microcomputer.

[0051] The control unit 40 has a running mode determination unit 41, a data processing unit 42, a fan control unit 43, and a switching unit 44 as functional elements. In other words, the control unit 40 functions as the running mode determination unit 41, the data processing unit 42, the fan control unit 43, and the switching unit 44 by executing the program stored in the storage device. The program stored in the control unit 40 causes the control unit 40 as a computer to at least execute a process of operating the air supply fan 30 of the air supply device 10 based on the first processed data described later.

[0052] (2-4-1) Running Mode Determination Unit The running mode determination unit 41 determines one running mode to be executed from a plurality of running modes according to the input of the user who operates the air supply device 10.

[0053] Among the multiple running modes of the present embodiment, there are a first running mode, a second running mode, a third running mode, a fourth running mode, a first automatic running mode, and a second automatic running mode. The details of each running mode and the running mode determination process performed by the running mode determination unit 41 will be described later.

[0054] (2-4-2) Data Processing Unit The data processing unit 42 processes the wind speed data (hereinafter referred to as raw data) included in the wind data received by the receiving unit 17 to generate first processed data. The first processed data is used in the first running mode. When the receiving unit 17 receives wind data during the execution of the first running mode, the data processing unit 42 generates the first processed data at any time.

[0055] The first processed data of the present embodiment is data obtained by processing the raw data in such a way that the average wind speed value of the air blown out from the air supply fan 30 becomes an average wind speed value arbitrarily set by the user. The average wind speed of the present embodiment is the average wind speed during a 30-second period (the first specified period).

[0056] Specifically, the first processed data is generated by multiplying each wind speed value of the raw data by a specified coefficient α. The specified coefficient α is calculated by dividing the average wind speed value arbitrarily set by the user by the average wind speed value received by the receiving unit 17. Thus, the average wind speed in a set of raw data is converted into the average wind speed desired by the user.

[0057] The data processing unit 42 processes the original data to generate second processed data. The second processed data is used in the fourth operation mode. When wind data is received by the receiving unit 17 during the execution of the fourth operation mode, the data processing unit 42 generates the second processed data at any time.

[0058] The second processed data is data obtained by processing the original data in such a way that the average wind speed value of the air blown out from the air supply fan 30 becomes an average wind speed value arbitrarily set by the user.

[0059] Specifically, in the present embodiment, the second processed data is generated by multiplying each wind speed value of the original data by a prescribed coefficient β. The prescribed coefficient β is calculated by dividing the average wind speed value arbitrarily set by the user by the average wind speed value received by the receiving unit 17. Thus, the average wind speed in a set of original data is converted into the average wind speed desired by the user.

[0060] (2-4-3) Fan control unit The fan control unit 43 controls the air supply fan 30. Specifically, the fan control unit 43 is configured to control the rotational speed (the number of revolutions per unit time) of the impeller 31 of each air supply fan 30 provided on the main body unit 15 based on the wind speed data.

[0061] In the fan control unit 43, the wind speed data used for controlling the air supply fan 30 varies depending on the operation mode being executed. Specifically, in the first operation mode, the first processed data is used. In the second and third operation modes, the wind speed data that keeps the original data as it is (hereinafter referred to as unprocessed data) is used. In the fourth operation mode, the second processed data is used.

[0062] Here, due to mechanical limitations, the upper limit value (maximum rotational speed) of the number of revolutions per unit time of the air supply fan 30 is determined. The wind speed blown out from the air supply fan 30 when the air supply fan 30 operates at the maximum rotational speed is the maximum wind speed of the air supply fan 30.

[0063] For example, in the case of operating the air supply fan 30 using the unprocessed data, as Figure 4 shown in A, in the region of the unprocessed data where the rotational speed exceeds the upper limit value of the air supply fan 30, the fan control unit 43 operates the air supply fan 30 at the maximum rotational speed. Therefore, in the region of the unprocessed data where the rotational speed exceeds the upper limit value of the air supply fan 30, a constant strong wind is blown out from the air supply fan 30.

[0064] In addition, in the air supply device 10 of the present embodiment, the user can arbitrarily set the upper limit wind speed of the air supply fan 30. In this case, for example, as Figure 4As shown in B of [], in the area of the unprocessed data where the wind speed exceeds any upper limit wind speed set by the user, the fan control unit 43 operates the air supply fan 30 so that the wind blown from the air supply fan 30 becomes the upper limit wind speed set by the user. Therefore, in the area of the unprocessed data where the wind speed exceeds the upper limit wind speed of the air supply fan 30, a constant and relatively strong wind is blown from the air supply fan 30. It should be noted that any upper limit wind speed set by the user is less than the maximum wind speed of the air supply fan 30.

[0065] (2-4-4) Switching unit During the execution of the first automatic operation mode or the second automatic operation mode, when a specified condition is satisfied, the switching unit 44 automatically switches the operation mode. The switching unit 44 determines whether the specified condition is established. Accordingly, the switching unit 44 automatically switches the operation mode. The switching operation performed by the switching unit 44 will be described later.

[0066] (2―5) Input unit The input unit 19 is for the user to input the average wind speed and upper limit wind speed of the air blown from the air supply fan 30, and the on or off of automatic switching. In addition, the input unit 19 is used for the user to directly input the operation mode executed by the control unit 40.

[0067] Regarding the average wind speed or upper limit wind speed of the air blown from the air supply fan 30, either a specific wind speed value can be input, or something other than a specific wind speed value can be input. In the case of inputting something other than a specific wind speed value, a wind speed level (for example, three levels of "strong", "medium", and "weak") can be selected for the upper limit wind speed or the average wind speed. In this case, the average wind speed value and upper limit wind speed value in each wind speed level are preset.

[0068] When the operation mode is input to the input unit 19, the user manually selects one operation mode to be executed from multiple operation modes. In this case, if the user selects an operation mode, the currently executed operation mode ends, and the operation mode selected by the user is executed. In this way, the air supply device 10 has the input unit 19, whereby the user can freely select the operation mode to be executed.

[0069] The input unit 19 is an operation button provided on the main body unit 15, an operation button of a remote controller equipped with the air supply device 10, an operation button displayed on the display of a communication terminal (for example, a smart phone, a tablet computer, a personal computer, etc.) that can communicate with the air supply device 10, and the like.

[0070] (3) Operation of the air supply device In the main body 15 of the air supply device 10 according to the present embodiment, the impellers 31 of the respective air supply fans 30 rotate at the same rotational speed as each other. Therefore, the blowing speeds of the sixteen air supply fans 30 arranged in a matrix on the main body 15 are substantially equal to each other. The air blown out by the sixteen air supply fans 30 is blown forward from the front surface of the main body 15, that is, the blowing area 16.

[0071] The air blown out from each air supply fan 30 and passing through the blowing area 16 diffuses with each other, and their respective wind speeds are averaged. As a result, Figure 3 On the entire imaginary plane V shown, the wind speed is substantially uniform. Here, the imaginary plane V is an imaginary plane represented by the rectangle ABCD in Figure 3 . This imaginary plane V is an imaginary rectangle opposite to the blowing area 16. The imaginary plane V is a vertical plane parallel to the blowing area 16. The long side of the imaginary plane V extends in the vertical direction. The short side of the imaginary plane V extends in the left-right direction.

[0072] (4) Operating action (4-1) Outline of each operating mode The first operating mode, the second operating mode, the third operating mode, the fourth operating mode, the first automatic operating mode, and the second operating mode will be described.

[0073] (4-1-1) First operating mode In the first operating mode, the air supply fan 30 is controlled based on the first processing data. In the first operating mode of the present embodiment, the air supply fan 30 is controlled based on the first processing data, and the first processing data is processed so that the wind speed of the air blown out from the air supply fan 30 reaches the average wind speed arbitrarily set by the user. It should be noted that in the first operating mode, the upper limit wind speed of the air blown out from the air supply fan 30 is not set by the user.

[0074] Here, an example of the original data is shown in Figure 5 . For example, as shown in Figure 6 , when the average wind speed arbitrarily set by the user is less than the average wind speed of the original data in Figure 5 , if the first operating mode is executed, the wind speed of the air blown out from the air supply fan 30 becomes weaker as a whole compared to the case where the original data is reproduced as it is. On the other hand, the fluctuation of the air blown out from the air supply fan 30 is the same as the fluctuation of the wind in the original data. Here, the fluctuation refers to the change rate of the wind speed. When the current wind speed (m / s) is set as v t , and the wind speed (m / s) one second ago is set as v t―1 , the change rate is represented by v t / v t―1 .

[0075] In this way, if the first operation mode is executed, the intensity of the air blown out from the air supply fan 30 can be weakened as a whole, and the fluctuation of the wind in the distance can be reproduced. Thus, for example, even if a strong wind or gust is detected in the distance, a very strong wind will not be reproduced in the air supply device 10, so the comfort of the person receiving the wind from the air supply device 10 will not be impaired.

[0076] It should be noted that when the average wind speed value arbitrarily set by the user is greater than Figure 5 the average wind speed value of the original data, if the first operation mode is executed, the wind speed of the air blown out from the air supply fan 30 becomes stronger as a whole compared to the case where the original data is reproduced as it is. Thus, for example, when a gentle breeze close to calm is detected in the distance, a wind with a certain degree of intensity is blown out from the air supply device 10.

[0077] In this way, according to the average wind speed arbitrarily set by the user, the wind speed of the air blown out from the air supply fan 30 can be weakened when the wind blown in the distance is strong, and the wind speed of the air blown out from the air supply fan 30 can be increased when the wind blown in the distance is weak.

[0078] Therefore, by executing the first operation mode, the air blown out from the air supply device 10 is as follows. The air is adjusted to be a wind with the intensity desired by the people in the target space S, so that the wind in the distance can be reproduced without impairing comfort. In addition, since the user can arbitrarily set the average wind speed, the intensity of the wind blowing towards the user can be changed according to the user's situation. Thus, the wind with the optimal intensity can be reproduced according to the user's usage situation.

[0079] (4-1-2) Second operation mode In the second operation mode, the air supply fan 30 is controlled based on the unprocessed data that keeps the original data as it is. It should be noted that in the second operation mode, the upper limit wind speed of the air blown out from the air supply fan 30 is not set by the user.

[0080] As Figure 7 shown, in the second operation mode, since the air supply fan 30 is controlled based on the unprocessed data, the intensity and fluctuation of the wind in the distance are reproduced as they are in the target space S.

[0081] (4-1-3) Third operation mode In the third operation mode, the upper limit wind speed of the air blown out from the air supply fan 30 is arbitrarily set by the user, and the air supply fan 30 is controlled based on the unprocessed data that keeps the original data as it is.

[0082] As Figure 8As shown, in the third operation mode, in the region below the upper limit wind speed set by the user in the unprocessed data, the intensity and fluctuation of the distant wind are reproduced in the target space S as they are. On the other hand, in the region exceeding the upper limit wind speed set by the user in the unprocessed data, air with the upper limit wind speed set by the user is blown out from the air supply fan 30. Thus, strong winds exceeding the upper limit wind speed set by the user are not reproduced, and people in the target space S are less likely to feel uncomfortable. As a result, it is possible to reproduce the distant wind without sacrificing comfort.

[0083] (4-1-4) Fourth operation mode In the fourth operation mode, the upper limit wind speed of the air blown out from the air supply fan 30 is arbitrarily set by the user, and the air supply fan 30 is controlled based on the second processed data. In the fourth operation mode of the present embodiment, the air supply fan 30 is controlled based on the second processed data, and the second processed data is processed so that the wind speed of the air blown out from the air supply fan 30 reaches the average wind speed arbitrarily set by the user.

[0084] In Figure 9 it shows the wind speed of the air supply fan 30 when the fourth operation mode is executed in the case where the average wind speed arbitrarily set by the user is less than Figure 5 the average wind speed value of the original data shown. As Figure 9 shown, in the region below the upper limit wind speed set by the user in the second processed data, compared with the case of reproducing the original data as it is, the wind speed of the air blown out from the air supply fan 30 becomes weaker as a whole. On the other hand, the fluctuation of the air blown out from the air supply fan 30 is the same as that of the original data. And, in the region exceeding the upper limit wind speed set by the user in the second processed data, air with the upper limit wind speed set by the user is blown out from the air supply fan 30.

[0085] In this way, if the fourth operation mode is executed, strong winds exceeding the upper limit wind speed set by the user are not reproduced. On the other hand, the intensity of the air blown out from the air supply fan 30 can be weakened as a whole, and the fluctuation of the distant wind can be reproduced. Thus, for example, in the case where strong winds or gusts are detected in the distance, very strong winds will not be blown out from the air supply device 10.

[0086] It should be noted that in the case where the average wind speed value arbitrarily set by the user is greater than Figure 5 the average wind speed value of the original data, if the fourth operation mode is executed, compared with the case of reproducing the original data as it is, the wind speed of the air blown out from the air supply fan 30 becomes stronger as a whole. Thus, for example, even in the case where a gentle breeze close to calm is detected in the distance, winds with a certain degree of intensity will be blown out from the air supply device 10.

[0087] In this way, according to the average wind speed set by the user, when the wind blowing in the distance is strong, the wind speed of the air blown out from the air supply fan 30 can be reduced, and when the wind blowing in the distance is weak, the wind speed of the air blown out from the air supply fan 30 can be increased.

[0088] Therefore, by executing the fourth operation mode, the air blown out from the air supply device 10 is adjusted to be the wind with the intensity desired by the people in the target space S. In addition, the upper limit wind speed of the air blown out from the air supply device 10 is restricted. As a result, the wind in the distance can be reproduced without compromising comfort.

[0089] (4-1-5) First automatic operation mode, second automatic operation mode In the first automatic operation mode, if the specified conditions are satisfied, it will automatically switch between the above first operation mode and the second operation mode. In the second automatic operation mode, if the specified conditions are satisfied, it will automatically switch between the above third operation mode and the fourth operation mode.

[0090] (4-2) Determination process of operation mode Next, refer to Figure 10 The determination process of the operation mode will be described. The operation mode determination unit 41 of the control unit 40 performs a determination process of determining one operation mode to be executed from among a plurality of operation modes. When the air supply device 10 starts to operate, the user inputs a specified item to the input unit 19. The operation mode determination unit 41 determines the operation mode to be executed based on this user input.

[0091] Specifically, if the input to the input unit 19 is started based on the user's operation, the control unit 40 performs the operation of step ST11. In step ST11, the control unit 40 determines whether the upper limit wind speed has been input to the input unit 19. When it is determined that the upper limit wind speed has not been input to the input unit 19 (\"No\" in step ST11), the control unit 40 executes step ST12. When it is determined that the upper limit wind speed has been input to the input unit 19 (\"Yes\" in step ST11), the control unit 40 stores the input upper limit wind speed in the storage unit 18 and executes step ST13.

[0092] In step ST12, the control unit 40 determines whether the average wind speed has been input to the input unit 19. When it is determined that the average wind speed has not been input to the input unit 19 (\"No\" in step ST12), the control unit 40 determines the operation mode to be executed as the second operation mode.

[0093] When it is determined that the average wind speed has been input to the input unit 19 (Yes in step ST12), the control unit 40 stores the input average wind speed in the storage unit 18 and executes step ST14. In step ST14, it is determined which of the automatic switching on and automatic switching off has been input to the input unit 19.

[0094] When the automatic switching off has been input to the input unit 19 (No in step ST14), the control unit 40 determines the operation mode to be executed as the first operation mode. When the automatic switching on has been input to the input unit 19 (Yes in step ST14), the control unit 40 determines the operation mode to be executed as the first automatic operation mode.

[0095] In step ST13, the control unit 40 determines whether the average wind speed has been input to the input unit 19. When it is determined that the average wind speed has not been input to the input unit 19 (No in step ST13), the control unit 40 determines the operation mode to be executed as the third operation mode.

[0096] When it is determined that the average wind speed has been input to the input unit 19 (Yes in step ST13), the control unit 40 stores the input average wind speed in the storage unit 18 and executes step ST15. In step ST15, it is determined which of the automatic switching on and automatic switching off has been input to the input unit 19.

[0097] When the automatic switching off has been input to the input unit 19 (No in step ST15), the control unit 40 determines the operation mode to be executed as the fourth operation mode. When the automatic switching on has been input to the input unit 19 (Yes in step ST15), the control unit 40 determines the operation mode to be executed as the second automatic operation mode.

[0098] (4-3) Operations of the first operation mode to the fourth operation mode Next, with reference to Figures 11 to 15 , the operations of the first operation mode to the fourth operation mode will be described.

[0099] (4-3-1) First operation mode, fourth operation mode In the first operation mode and the fourth operation mode, the control unit 40 performs the same action processing. Hereinafter, the first operation mode will be taken as an example for description.

[0100] As Figure 11 shown, in the operation mode determination process, if the operation mode to be executed is determined as the first operation mode, the control unit 40 executes step ST21. In step ST21, the storage unit 18 stores the wind data received by the receiving unit 17.

[0101] In step ST22, the control unit 40 generates first processing data based on the wind speed data included in the wind data stored in step ST21. Thus, wind speed data is generated, and the wind speed data is processed so that the average wind speed of the air blown out from the air supply fan 30 reaches the average wind speed arbitrarily set by the user.

[0102] In step ST23, the control unit 40 controls the air supply fan 30 based on the first processing data generated in step ST22. Thus, the wind in the distance is adjusted to have the average wind speed arbitrarily set by the user, and the adjusted wind is used to reproduce the wind in the distance. Therefore, it is possible to reproduce the wind in the distance without impairing the comfort of the person in the target space S. It should be noted that in the first operation mode, the upper limit wind speed of the air supply fan 30 is the maximum wind speed of the air supply fan 30. Therefore, in the first operation mode, in the region of the first processing data that exceeds the maximum wind speed of the air supply fan 30, air with the maximum wind speed of the air supply fan 30 is blown out from the air supply fan 30.

[0103] The control unit 40 stops the first operation mode at the end of step ST23. The control unit 40 may also execute step ST21 again after step ST23 ends. In this case, the control unit 40 performs the actions of the first operation mode until an instruction to stop the operation of the air supply device 10 or an instruction to change the operation mode of the air supply device 10 to another operation mode is input to the input unit 19.

[0104] As described above, the first processing data is generated in step ST22 in the first operation mode, and the second processing data is generated in step ST22 in the fourth operation mode. In this case, wind speed data is generated, and the wind speed data is processed so that the average wind speed of the air blown out from the air supply fan 30 reaches the average wind speed arbitrarily set by the user.

[0105] In addition, in step ST23 of the first operation mode, the upper limit wind speed of the air supply fan 30 is the maximum wind speed of the air supply fan 30, and in step ST23 of the fourth operation mode, the upper limit wind speed of the air supply fan 30 is the upper limit wind speed arbitrarily set by the user. Therefore, in the fourth operation mode, in the region of the second processing data that exceeds the set upper limit wind speed, air with the set upper limit wind speed is blown out from the air supply fan 30.

[0106] (4-3-2) Second operation mode, third operation mode In the second operation mode and the third operation mode, the control unit 40 performs the same action processing. Hereinafter, the second operation mode will be described as an example.

[0107] As Figure 12As shown, in the operation mode determination process, if the operation mode to be executed is determined to be the second operation mode, the control unit 40 executes step ST31. In step ST31, the storage unit 18 stores the wind data received by the reception unit 17.

[0108] In step ST32, the control unit 40 controls the air supply fan 30 based on the unprocessed data, which is the data in which the wind speed data included in the wind data stored in step ST31 remains as it is. Thus, the distant wind is reproduced as it is in the target space S. It should be noted that in the second operation mode, the upper limit wind speed of the air supply fan 30 is the maximum wind speed of the air supply fan 30. Therefore, in the second operation mode, in the region where the wind speed in the unprocessed data exceeds the maximum wind speed of the air supply fan 30, air with the maximum wind speed is blown out from the air supply fan 30.

[0109] The control unit 40 stops the second operation mode at the end of step ST32. The control unit 40 may also execute step ST31 again after the end of step ST32. In this case, the control unit 40 performs the operation of the second operation mode until an instruction to stop the operation of the air supply device 10 or an instruction to change the operation mode of the air supply device 10 to another operation mode is input to the input unit 19.

[0110] As described above, in step ST32 of the second operation mode, the upper limit wind speed of the air supply fan 30 is the maximum wind speed of the air supply fan 30, and in step ST32 of the third operation mode, the upper limit wind speed of the air supply fan 30 is the upper limit wind speed arbitrarily set by the user. Therefore, in the third operation mode, in the region where the wind speed in the unprocessed data exceeds the set upper limit wind speed, air with the upper limit wind speed is blown out from the air supply fan 30.

[0111] (4-4) Switching operation between the first automatic operation mode and the second automatic operation mode (4-4-1) Technical problems of the second operation mode and the third operation mode As Figure 13 shown in A of, in the case where the reception unit 17 receives wind speed data such as a very large wind speed value exceeding the maximum wind speed of the air supply fan 30 and the state of the large wind speed value continues for a long time, in the second operation mode, as Figure 13 shown in B of, in the region where the wind speed in the unprocessed data exceeds the maximum wind speed of the air supply fan 30, air with a constant maximum wind speed and no fluctuation is blown out from the air supply fan 30.

[0112] In addition, the same is true in the third operation mode. In the case of receiving the wind speed data as Figure 13 shown in A of Figure 13As shown in C of FIG. 0, in the area of the unprocessed data where the wind speed exceeds the upper limit wind speed arbitrarily set by the user, a constant air with the upper limit wind speed and no fluctuation is blown out from the air supply fan 30.

[0113] (4-4-2) Switching operation of the first automatic operation mode Regarding the technical problem of the above-mentioned second operation mode, by executing the first automatic operation mode, fluctuating air can be continuously blown out from the air supply fan 30. In the first automatic operation mode, if the specified conditions are met, it will automatically switch between the above-mentioned first operation mode and the second operation mode. The switching operation of this first automatic operation mode will be described. In the following description, it is assumed that in the first automatic operation mode, the air supply device 10 is operating in the second operation mode.

[0114] As Figure 14 shown, in the first automatic operation mode, during the execution of the second operation mode (step ST41), the control unit 40 executes step ST42. In step ST42, it is judged whether the first condition is established. The first condition refers to the state where the wind speed value of the wind speed data received by the receiving unit 17 exceeds the maximum wind speed of the air supply fan 30 and continues for more than a specified time.

[0115] If it is judged that the first condition is not established (\"No\" in step ST42), the control unit 40 executes step ST41. If it is judged that the first condition is established (\"Yes\" in step ST42), the control unit 40 executes step ST43. In step ST43, the control unit 40 executes the first operation mode.

[0116] In this way, if the first condition is established, the operation of the air supply device 10 automatically switches from the second operation mode to the first operation mode. Thus, in the case of receiving the original data as shown in A of FIG. Figure 13 , as Figure 13 shown in D of FIG., the area exceeding the maximum wind speed of the air supply fan 30 is reduced, so that the fluctuation of the wind in the distance can be continuously reproduced.

[0117] During the execution of the first operation mode (step ST43), the control unit 40 executes step ST44. In step ST44, it is judged whether the second condition is established. The second condition refers to the state where the time during which the wind speed value of the wind speed data received by the receiving unit 17 exceeds the maximum wind speed of the air supply fan 30 continues for less than a specified time.

[0118] If it is judged that the second condition is not established (\"No\" in step ST44), the control unit 40 executes step ST43. If it is judged that the second condition is established (\"Yes\" in step ST44), the control unit 40 ends the first automatic operation mode and then executes step ST41 again.

[0119] In this way, if the second condition is satisfied, the operation of the air supply device 10 is automatically switched from the first operation mode to the second operation mode. This is because: when the second condition is satisfied, no such technical problems as described above will occur even if the second operation mode is executed. Thus, it is possible to reproduce the wind in the distance as it is as much as possible, and to continuously reproduce the fluctuations of the wind in the distance even when it is impossible to reproduce the wind in the distance as it is.

[0120] Also in the first automatic operation mode: the control unit 40 executes the actions of the first automatic operation mode until an instruction to stop the operation of the air supply device 10 or an instruction to change the operation mode of the air supply device 10 to another operation mode is input to the input unit 19.

[0121] (4-4-3) Switching operation of the second automatic operation mode Regarding the technical problems of the above-described third operation mode, by executing the second automatic operation mode, it is possible to continuously blow fluctuating air from the air supply fan 30. In the second automatic operation mode, if a specified condition is satisfied, it will automatically switch between the above-described third operation mode and the fourth operation mode. The switching operation of this second automatic operation mode will be described. In the following description, it is assumed that in the second automatic operation mode, the air supply device 10 is operating in the third operation mode.

[0122] As Figure 15 shown, in the second automatic operation mode, during the execution of the third operation mode (step ST51), the control unit 40 executes step ST52. In step ST52, it is judged whether the third condition is satisfied. The third condition means that the state in which the wind speed value of the wind speed data received by the receiving unit 17 exceeds the upper limit wind speed set by the user continues for a specified time or more.

[0123] When it is judged that the third condition is not satisfied (\"No\" in step ST52), the control unit 40 executes step ST51. When it is judged that the third condition is satisfied (\"Yes\" in step ST52), the control unit 40 executes step ST53. In step ST53, the control unit 40 executes the fourth operation mode.

[0124] In this way, if the third condition is satisfied, the operation of the air supply device 10 is automatically switched from the third operation mode to the fourth operation mode. Thus, when the original data as shown in Figure 13 A is received, as shown in Figure 13 E, the area exceeding the upper limit wind speed arbitrarily set by the user is reduced, so that it is possible to continuously reproduce the fluctuations of the wind in the distance.

[0125] During the execution of the fourth operation mode (step ST53), the control unit 40 executes step ST54. In step ST54, it is determined whether the fourth condition is satisfied. The fourth condition means that the duration for which the wind speed value of the wind speed data received by the receiving unit 17 exceeds the upper limit wind speed set by the user is less than a specified time.

[0126] When it is determined that the fourth condition is not satisfied (\"No\" in step ST54), the control unit 40 executes step ST53. When it is determined that the fourth condition is satisfied (\"Yes\" in step ST54), the control unit 40 ends the second automatic operation mode and then executes step ST51 again.

[0127] In this way, if the fourth condition is satisfied, the operation of the air blower 10 automatically switches from the fourth operation mode to the third operation mode. This is because: when the fourth condition is satisfied, no such technical problem as described above will occur even if the third operation mode is executed. Thus, it is possible to reproduce the wind in the distance as it is as much as possible, and it is also possible to continuously reproduce the fluctuations of the wind in the distance when it is impossible to reproduce the wind in the distance as it is.

[0128] Also in the second automatic operation mode: the control unit 40 executes the actions of the second automatic operation mode until an instruction to stop the operation of the air blower 10 or an instruction to change the operation mode of the air blower 10 to another operation mode is input to the input unit 19.

[0129] (5) Features (5-1) The air blower 10 of the present embodiment includes a receiving unit 17 that receives wind data regarding the wind in the distance via a communication line 45, a fan 30 that blows air into the target space S, and a control unit 40 that controls the air supply fan 30. The control unit 40 performs a first operation mode, in which the air supply fan 30 is operated based on first processed data obtained by processing the wind data received by the receiving unit 17.

[0130] In the first operation mode of the present embodiment, since the fan 30 is operated using the first processed data obtained by processing the wind data received by the receiving unit 17, the adjusted air is blown out from the air supply fan 30. Thus, it is possible to reproduce the wind in the natural environment without impairing the comfort of the people in the target space S.

[0131] (5-2) In the air blower 10 of the present embodiment, the first processed data is data obtained by processing the wind data in such a way that the average wind speed of the air blown out from the air supply fan 30 reaches the average wind speed arbitrarily set by the user.

[0132] Thus, in the first operation mode, wind with an intensity freely set by the user and having the same fluctuations as the wind in the distance is reproduced in the target space S.

[0133] (5-3) In the air supply device 10 of the present embodiment, the first processing data is generated by multiplying the time series data of the wind speed value by a prescribed coefficient. Thereby, the intensity of the air blown out from the air supply fan 30 can be adjusted, and the fluctuations of the wind in the distance can be reproduced.

[0134] (5-4) In the air supply device 10 of the present embodiment, the receiving unit 17 receives wind data within a first prescribed period. And the average wind speed when generating the first processing data is the average value of the wind speed within the first prescribed period.

[0135] (5-5) In the air supply device 10 of the present embodiment, the control unit 40 executes one operation mode from among a plurality of operation modes. The plurality of operation modes includes a second operation mode in which the wind data received by the receiving unit 17 is used as it is to operate the air supply fan 30.

[0136] Therefore, by the control unit 40 executing the second operation mode, the wind in the distance can be reproduced as it is in the target space S. Thereby, when it is not necessary for a person in the target space S to adjust the air blown out from the air supply device 10, the wind in the distance can be felt as it is.

[0137] (5-6) In the air supply device 10 of the present embodiment, the plurality of operation modes includes a first automatic operation mode that automatically switches between the first operation mode and the second operation mode. Thereby, by the control unit 40 executing the first automatic operation mode, it is possible to automatically switch between the first operation mode and the second operation mode.

[0138] (5-7) In the air supply device 10 of the present embodiment, in the first automatic operation mode, if, during the execution of the second operation mode, the state where the received wind speed value exceeds the maximum wind speed of the air supply fan 30 continues for a prescribed time or more, then it switches to the first operation mode; if, during the execution of the first operation mode, the time for which the state where the received wind speed value exceeds the maximum wind speed of the air supply fan 30 continues is less than the prescribed time, then it switches to the second operation mode.

[0139] If, during the execution of the second operation mode, the state where the received wind speed value exceeds the maximum wind speed of the air supply fan 30 continues for a certain period of time, the wind speed of the air blown out from the air supply fan 30 will become constant, and the fluctuations of the distant wind will not be reproduced. Thus, in the present embodiment, by switching to the first operation mode in such a case, it is possible to reproduce the fluctuations of the distant wind in the target space S.

[0140] On the other hand, if, during the execution of the first operation mode, the state where the received wind speed value exceeds the maximum wind speed of the air supply fan 30 continues for a time shorter than the specified time, the fluctuations of the distant wind can be reproduced to a certain extent even if switched to the second operation mode. Therefore, in this case, it is switched to the second operation mode.

[0141] In this way, in the present embodiment, by causing the control unit 40 to execute the first automatic operation mode, it is possible to continuously reproduce the fluctuations of the distant wind.

[0142] (5-8) In the air supply device 10 of the present embodiment, the plurality of operation modes include a third operation mode in which the wind data is used as it is to operate the air supply fan 30 and the upper limit wind speed of the air blown out from the air supply fan 30 is arbitrarily set by the user.

[0143] When a person in the target space S is blown by the wind blown out from the fan 30, sometimes they dislike strong wind. In the present embodiment, in the third operation mode, since the upper limit wind speed of the air blown out from the fan 30 can be arbitrarily set, even when a person dislikes strong wind, it is possible to reproduce the wind in the natural environment without impairing comfort.

[0144] (5-9) In the air supply device 10 of the present embodiment, the plurality of operation modes further include a fourth operation mode in which the second processed data obtained by processing the wind data is used to operate the air supply fan 30 and the upper limit wind speed of the air blown out from the air supply fan 30 is arbitrarily set by the user.

[0145] In the present embodiment, in the fourth operation mode, since the upper limit wind speed of the air blown out from the air supply fan 30 can be arbitrarily set, even when a person in the target space S dislikes strong wind, it is not easy to impair comfort. In addition, in the fourth operation mode, since the second processed data is used to operate the fan 30, the air blown out from the air supply fan 30 is adjusted. As a result, it is possible to reproduce the wind in the natural environment without impairing the comfort of the person in the target space S.

[0146] (5-10) In the air supply device 10 of the present embodiment, the second processed data is data obtained by processing wind data in such a manner that the average wind speed of the air blown out from the air supply fan 30 reaches an average wind speed value arbitrarily set by the user. Thus, in the fourth operation mode, wind with an intensity freely set by the user and fluctuations identical to those of the wind in the distance is reproduced in the target space S.

[0147] (5-11) In the air supply device 10 of the present embodiment, the second processed data is generated by multiplying the time series data of the wind speed values by a prescribed coefficient. Thus, the intensity of the air blown out from the air supply fan 30 can be adjusted, and the fluctuations of the wind in the distance can be reproduced.

[0148] (5-12) In the air supply device 10 of the present embodiment, the receiving unit 17 receives wind data within a first prescribed period. The average wind speed when generating the second processed data is the average value of the wind speeds within the first prescribed period.

[0149] (5-13) In the air supply device 10 of the present embodiment, the plurality of operation modes includes a second automatic operation mode for automatically switching between the third operation mode and the fourth operation mode. Thus, by the control unit 40 executing the second automatic operation mode, it is possible to automatically switch between the third operation mode and the fourth operation mode.

[0150] (5-14) In the air supply device 10 of the present embodiment, in the second automatic operation mode, if, during the execution of the third operation mode, the state where the received wind speed value exceeds an arbitrarily set upper limit wind speed continues for a prescribed time or more, then it is switched to the above-mentioned fourth operation mode; if, during the execution of the fourth operation mode, the time for which the state where the received wind speed value exceeds an arbitrarily set upper limit wind speed continues is less than the prescribed time, then it is switched to the third operation mode.

[0151] If, during the execution of the third operation mode, the state where the received wind speed value exceeds an arbitrarily set upper limit wind speed continues for a certain period of time, the wind speed of the air blown out from the air supply fan 30 becomes constant, and the fluctuations of the wind in the distance are not reproduced. Thus, in the present embodiment, by switching to the fourth operation mode in such a case, it is possible to reproduce the fluctuations of the wind in the distance in the target space S.

[0152] On the other hand, if the state where the received wind speed value exceeds the arbitrarily set upper limit wind speed during the execution of the fourth operation mode continues for less than the specified time, the fluctuation of the distant wind can be reproduced to a certain extent even when switching to the third operation mode. Therefore, in this case, the mode is switched to the third operation mode.

[0153] In this way, in the present embodiment, by executing the second automatic operation mode by the control unit 40, the fluctuation of the distant wind can be continuously reproduced.

[0154] (5-15) The air supply device 10 of the present embodiment further includes an input unit 19 for manually selecting one operation mode to be executed from a plurality of operation modes. Thereby, the user can freely select the operation mode to be executed.

[0155] (5-16) In the air supply device 10 of the present embodiment, the receiving unit 17 receives wind data within the first specified period. The control unit 40 controls the air supply fan 30 based on the wind data within the first specified period.

[0156] (5-17) The air supply system 1 of the present embodiment includes an air supply device 10 and a sensor unit 50 provided at a distance. The sensor unit 50 has a sensor 51 for detecting wind data and a transmitting unit 52 for transmitting the above-mentioned wind data detected by the sensor 51. Thereby, an air supply system 1 can be provided, which can reproduce the wind in the natural environment without impairing the comfort of people in the target space S.

[0157] (5-18) The program of the present embodiment is a program for causing a computer to execute the following processing: in this processing, the fan 30 of the air supply device 10 that reproduces the distant wind in the target space S is controlled. The program of the present embodiment causes the computer to execute the following processing: in this processing, the first operation mode in which the air supply fan 30 operates based on the first processed data, which is obtained by processing the wind data regarding the distant wind received by the receiving unit 17, is performed. Thereby, a program can be provided, which can reproduce the wind in the natural environment without impairing the comfort of people in the target space S.

[0158] (6) Variation (6-1) Variation 1 In the air supply device 10 of the above-described embodiment, the upper limit value of the rotational speed of the air supply fan 30 per unit time may be set to, for example, an upper limit value preset during manufacturing, rather than the upper limit value in the specification of the air supply fan 30. The upper limit value of the rotational speed preset during manufacturing is less than the upper limit value of the rotational speed in the specification.

[0159] In this case, during the execution of the first operation mode, in the region of the first processing data where the rotational speed exceeds the upper limit value of the air supply fan 30 preset in advance, the fan control unit 43 of the control unit 40 causes the air supply fan 30 to operate at the upper limit value of the rotational speed preset in advance. During the execution of the second operation mode, in the region of the non-processing data where the rotational speed exceeds the upper limit value of the air supply fan 30 preset in advance, the fan control unit 43 causes the air supply fan 30 to operate at the upper limit value of the rotational speed preset in advance.

[0160] In addition, in this case, the first condition for the control unit 40 to perform the first automatic operation mode is that the state where the wind speed value of the wind speed data received by the receiving unit 17 exceeds the upper limit value of the rotational speed of the air supply fan 30 preset in advance continues for a specified time or more. And the second condition is that the time during which the state where the wind speed value of the wind speed data received by the receiving unit 17 exceeds the upper limit value of the rotational speed of the air supply fan 30 preset in advance continues is less than the specified time.

[0161] In this way, by presetting the upper limit value of the rotational speed of the air supply fan 30, extremely strong wind in the distance will not be reproduced. Thus, it is possible to reproduce the wind in the natural environment without impairing the comfort of people in the target space S.

[0162] (6-2) Variant Example 2 In the air supply device 10 of the above-described embodiment, the control unit 40 may also perform only the first operation mode. In addition, in the air supply device 10 of the above-described embodiment, as the plurality of operation modes, it may have only the first operation mode and the second operation mode, may have only the first operation mode to the third operation mode, may have only the first operation mode and the third operation mode, or may have only the first operation mode, the third operation mode, and the fourth operation mode.

[0163] 《Second Embodiment》 The second embodiment will be described. The air supply device 10 of this embodiment is obtained by adding the sound generation unit 20 to the air supply device 10 of the first embodiment. Here, the differences between the air supply device 10 of this embodiment and the first embodiment will be described.

[0164] (1) Sound Generation Unit As Figure 16As shown, the air supply device 10 of the present embodiment further includes a sound generating unit 20. The sound generating unit 20 is, for example, a speaker. The sound generating unit 20 emits sounds that simulate a natural environment. The sounds that simulate a natural environment are, for example, the sound of wind blowing, the sound of grass and trees swaying, the sound of withered leaves falling, the gurgling sound of a river, the chirping of birds, etc. The sound emitted by the sound generating unit 20 of the present embodiment includes the sound of wind blowing.

[0165] (2) Control unit The control unit 40 adjusts the volume of the sound generated by the sound generating unit 20. In the present embodiment, the control unit 40 changes the volume of the sound of wind blowing based on the wind speed data included in the wind data received by the receiving unit 17.

[0166] In Figure 17 , the relationship is shown when the received wind speed value is taken as the horizontal axis and the volume is taken as the vertical axis. As Figure 17 shown, in the present embodiment, if the wind speed value of the received wind speed data increases, the control unit 40 increases the volume of the sound of wind blowing. If the wind speed value of the received wind speed data decreases, the control unit 40 decreases the volume of the sound of wind blowing.

[0167] (3) Features (3-1) The air supply device 10 of the present embodiment includes a sound generating unit 20 that emits sounds that simulate a natural environment. Thus, a person in the target space S can feel a sense of being in nature (natural feeling).

[0168] (3-2) Among the sounds that simulate a natural environment emitted by the sound generating unit 20 of the present embodiment, the sound of wind blowing is included. And, the control unit 40 changes the volume of the sound of wind blowing based on data about the wind. Thus, the strength of the wind in the distance that is reproduced can be felt through hearing.

[0169] (4) Variation (4-1) Variation 1 In the above embodiment, it can also be: when the wind speed value of the wind speed data received by the receiving unit 17 exceeds the upper limit value of the wind speed blown out by the air supply fan 30 in the currently executing operation mode, the control unit 40 changes the volume of the sound of wind blowing according to the difference between the received wind speed value and the upper limit value of the wind speed in the currently executing operation mode.

[0170] As Figure 18As shown, when receiving the wind speed value, as the difference between the received wind speed value and the upper limit wind speed increases, the sound of the blowing wind emitted from the sound generation unit 20 becomes louder, where the above wind speed value exceeds the upper limit wind speed in the currently executing operation mode. In the first operation mode and the second operation mode, the upper limit wind speed is the upper limit value of the rotation speed of the air supply fan 30, and in the third operation mode and the fourth operation mode, the upper limit wind speed is the upper limit wind speed value arbitrarily set by the user.

[0171] When the received wind speed value exceeds the upper limit value of the wind speed in the currently executing operation mode, since the air blown out from the air supply fan 30 continues to blow at the upper limit wind speed and the wind speed does not change, the fluctuations of the wind in the distance are not reproduced. In contrast, in this modification example, since the volume of the blowing wind sound is changed according to the difference between the received wind speed value and the upper limit wind speed in the currently executing operation mode, the intensity of the wind in the distance can be felt through hearing.

[0172] It should be noted that in this modification example, when receiving a wind speed value below the upper limit wind speed value in the currently executing operation mode, the blowing wind sound can be emitted at a constant volume or the volume can be changed.

[0173] (4-2) Modification Example 2 In the above embodiment, it can also be: The control unit 40 changes the ratio of the volumes of the wind sound and the natural sound based on the wind speed data included in the wind data. In this case, the sound simulating the natural environment emitted from the sound generation unit 20 includes the wind sound caused by the wind and natural sounds of different types from the wind sound. The sound caused by the wind refers to, for example, the sound of the blowing wind, the sound of the grass and trees swaying, the sound of the withered leaves falling, etc. The natural sounds of different types from the wind sound refer to, for example, the gurgling sound of the river, the chirping sound of the birds, etc.

[0174] As Figure 19 shown, for example, the control unit 40 changes the volume in such a way that the wind sound becomes louder and the natural sound becomes smaller as the received wind speed value increases. The control unit 40 changes the volume in such a way that the wind sound becomes smaller and the natural sound becomes larger as the received wind speed value decreases.

[0175] In this way, since the control unit 40 changes the ratio of the volumes of the wind sound and the natural sound, the volume of the wind sound relative to the volume of the natural sound changes according to the intensity of the wind in the distance. Thereby, the intensity of the wind in the distance can be felt through hearing.

[0176] 《Third Embodiment》 A description is given of the third embodiment. The air supply system 1 of this embodiment is obtained by changing the structure of the air supply device 10 in the air supply system 1 of the first embodiment. Here, the differences between the air supply system 1 of this embodiment and the air supply system 1 of the first embodiment are described.

[0177] (1) Air supply system As Figure 20 shown, the air supply system 1 of this embodiment includes an air volume adjustment device A. The air volume adjustment device A is a device that outputs a control value of the fan 30 for adjusting the air volume of the fan 30. The fan 30 reproduces distant wind in the target space S. The air volume adjustment device A of this embodiment is included in the air supply device 10. In other words, the air volume adjustment device A of this embodiment constitutes a part of the air supply device 10. The air volume adjustment device A includes a control unit C that outputs a control value of the air supply fan 30.

[0178] (2) Sensor unit The sensor unit 50 has a sensor 51, a sensor-side communication unit 52, a sensor-side storage unit 53, and a sensor-side control unit 54. The sensor 51 is the same as that in the first embodiment.

[0179] The sensor-side communication unit 52 is communicably connected to the air supply device 10 via a communication line 45 such as the Internet. The sensor-side communication unit 52 has the function of the transmission unit 52 in the first embodiment and the function of a reception unit that receives a signal transmitted from the air supply device 10.

[0180] The sensor-side storage unit 53 stores the detection value of the sensor 51. The sensor-side storage unit 53 has the same structure as the storage unit 18 in the first embodiment. The sensor-side control unit 54 has the same structure as the control unit 40 in the first embodiment.

[0181] (3) Air supply device The air supply device 10 has a main body portion 15 including an air supply fan 30, an air supply-side communication unit 17, an air supply-side storage unit 18, an air supply-side control unit 40, and an input unit 19. In this embodiment, the air supply fan 30, the main body portion 15, and the input unit 19 are the same as those in the first embodiment.

[0182] The air supply-side communication unit 17 is communicably connected to the sensor unit 50 via a communication line 45 such as the Internet. The air supply-side communication unit 17 has the function of the reception unit 17 in the first embodiment and the function of a transmission unit that transmits a signal from the air supply device 10 to the sensor unit 50.

[0183] The air supply side storage unit 18 stores the wind data received by the air supply side communication unit 17. The air supply side storage unit 18 is the same as the storage unit 18 in the first embodiment. The air supply side control unit 40 has the same structure as the control unit 40 in the first embodiment.

[0184] The air supply side control unit 40 has an acquisition unit c1 and an output determination unit c2 instead of the data processing unit 42 in the first embodiment as functional elements. The air supply side control unit 40 functions as an operation mode determination unit 41, an acquisition unit c1, an output determination unit c2, a fan control unit 43, and a switching unit 44 by executing the program stored in the storage device.

[0185] Here, the air supply side control unit 40 of the present embodiment corresponds to the control unit C of the air volume adjustment device A of the present disclosure. The control unit C of the air volume adjustment device A has a function of acquiring wind data and a function of outputting a control value of the fan 30 different from the control value corresponding to the acquired wind data. The "control value corresponding to the acquired wind data" means the control value of the air supply fan 30 that reproduces the wind of the acquired wind speed data as it is.

[0186] The acquisition unit c1 of the air supply side control unit 40 corresponds to the function of acquiring wind data in the control unit C of the air volume adjustment device A. The acquisition unit c1 acquires the wind data acquired remotely. In the present embodiment, the acquisition unit c1 acquires the wind data stored in the air supply side storage unit 18.

[0187] The output determination unit c2 of the air supply side control unit 40 corresponds to the function of outputting a control value of the air supply fan 30 different from the control value corresponding to the acquired wind data in the control unit C of the air volume adjustment device A. The output determination unit c2 of the present embodiment has a data processing unit c3 and a control value determination unit c4.

[0188] The data processing unit c3 generates processed data obtained by processing the wind data. The control value determination unit c4 determines the control value of the air supply fan 30 to be output based on the processed data generated by the data processing unit c3 and outputs the determined control value. As the control value output from the control value determination unit c4, for example, an electric current value for controlling the air supply fan 30 is output.

[0189] In this way, in the present embodiment, since the control value of the air supply fan 30 to be output is determined by the control value determination unit c4 based on the processed data obtained by processing the wind data, the control value of the air supply fan 30 output from the output determination unit c2 is different from the control value corresponding to the acquired wind data.

[0190] The data processing unit c3 in this embodiment is the same as the data processing unit c3 in the first embodiment. Therefore, in the data processing unit c3 of this embodiment, the same first processed data and second processed data as those in the first embodiment are generated.

[0191] Since the first processed data and the second processed data are data processed such that the average wind speed value of the air blown out from the air supply fan 30 becomes an average wind speed value arbitrarily set by the user, the first processed data and the second processed data show the same tendency as the increase and decrease tendency of the wind speed in the original data. In short, the first processed data and the second processed data are data that change the wind intensity relative to the original data but maintain the increase and decrease tendency of the wind speed. Since the control value determination unit c4 determines the control value to be output based on such first processed data or second processed data, a control value showing the same tendency as the increase and decrease tendency of the wind speed in the original data is output from the output determination unit c2.

[0192] The program stored in the transmission side control unit C causes the transmission side control unit C as a computer to at least execute a process of acquiring wind data obtained remotely and a process of outputting a control value different from the control value corresponding to the acquired wind data. The fan control unit 43 controls the air supply fan 30 based on the control value output from the output determination unit c2.

[0193] (4) Operating actions (4 - 1) Outline of each operating mode In the air supply system 1 of this embodiment, the first operating mode, the second operating mode, the third operating mode, the fourth operating mode, the first automatic operating mode, and the second automatic operating mode are executed in the same manner as in the first embodiment. The content of each operating mode is the same as that in the first embodiment.

[0194] (4 - 2) Determination process of the operating mode The determination process of the operating mode in this embodiment is the determination process after replacing the control unit C with the air supply side control unit 40 and replacing the storage unit 18 with the air supply side storage unit 18 in (4 - 2) of the first embodiment.

[0195] (4 - 3) Actions of the first to fourth operating modes Refer to Figure 21 and Figure 22 to describe the actions of the first to fourth operating modes in this embodiment.

[0196] (4 - 3 - 1) First operating mode, fourth operating mode In the first operating mode and the fourth operating mode, the air supply side control unit 40 performs the same action process. Hereinafter, the first operating mode will be used as an example for description.

[0197] As Figure 21 shown, in the operation mode determination process, if the operation mode to be executed is determined to be the first operation mode, the air supply side control unit 40 executes step ST321. In step ST321, the air supply side storage unit 18 stores the wind data received by the air supply side communication unit 17.

[0198] Next, the air supply side control unit 40 executes step ST322. In step ST322, the air supply side control unit 40 obtains the wind speed data included in the wind data stored in step ST321 from the air supply side storage unit 18.

[0199] Next, the air supply side control unit 40 executes step ST323. In step ST323, the air supply side control unit 40 generates first processed data based on the obtained wind speed data.

[0200] Next, the air supply side control unit 40 executes step ST324. In step ST324, the air supply side control unit 40 determines the control value of the air supply fan 30. Specifically, the air supply side control unit 40 determines the control value to be output based on the first processed data. Thus, the control value of the air supply fan 30 corresponding to the first processed data is determined and output.

[0201] Next, the air supply side control unit 40 executes step ST325. In step ST325, the air supply side control unit 40 controls the air supply fan 30 based on the output control value. Thus, the wind in the distance is adjusted to an average wind speed arbitrarily set by the user, and the adjusted wind is used to reproduce the wind in the distance. Therefore, it is possible to reproduce the wind in the distance without impairing the comfort of the people in the target space S.

[0202] The air supply side control unit 40 stops the first operation mode at the end of step ST325. The air supply side control unit 40 may also execute step ST321 again after the end of step ST325. In this case, the air supply side control unit 40 continues to execute the actions of the first operation mode until an instruction to stop the operation of the air supply device 10 or an instruction to change the operation mode of the air supply device 10 to another operation mode is input to the input unit 19.

[0203] As described above, the first processed data is generated in step ST323 in the first operation mode, and the second processed data is generated in step ST323 in the fourth operation mode.

[0204] In addition, in step ST325 of the first operation mode, the upper limit wind speed of the air supply fan 30 is the maximum wind speed of the air supply fan 30, and in step ST325 of the fourth operation mode, the upper limit wind speed of the air supply fan 30 is the upper limit wind speed arbitrarily set by the user.

[0205] (4 - 3 - 2) Second operation mode, third operation mode In the second operation mode and the third operation mode, the air supply side control unit 40 performs the same action process. Hereinafter, the second operation mode will be described as an example. As Figure 22 shown, compared with the first operation mode, in the second operation mode, step ST323 is not executed.

[0206] Specifically, step ST331 to step ST334 of the second operation mode are the same as step ST321, ST322, ST324, and ST325 of the first operation mode respectively. It should be noted that in step ST333 of the second operation mode, the air supply side control unit 40 determines the control value to be output based on the acquired wind speed data as it is, that is, the unprocessed data. Thus, the control value of the air supply fan 30 corresponding to the unprocessed data is determined and output. As a result, in the second operation mode, the wind in the distance is reproduced in the target space S as it is.

[0207] In step ST334 of the second operation mode, the upper limit wind speed of the air supply fan 30 is the maximum wind speed of the air supply fan 30, and in step ST334 of the third operation mode, the upper limit wind speed of the air supply fan 30 is the upper limit wind speed arbitrarily set by the user. Therefore, in the third operation mode, in the area where the wind speed in the unprocessed data exceeds the set upper limit wind speed, air with the upper limit wind speed is blown out from the air supply fan 30.

[0208] (4 - 4) Switching operation between the first automatic operation mode and the second automatic operation mode The switching operation between the first automatic operation mode and the second automatic operation mode of the present embodiment is the switching operation after replacing the control unit C with the air supply side control unit 40 and the receiving unit 17 with the air supply side communication unit 17 in (4 - 4) of the first embodiment.

[0209] In the first automatic operation mode, the air supply side control unit 40 determines whether the first condition is satisfied. If the result is that the first condition is satisfied, it switches from the second operation mode to the first operation mode. Here, the first condition means that the state where the wind speed value of the wind speed data received by the air supply side communication unit 17 exceeds the maximum wind speed of the air supply fan 30 continues for a specified time or more. That is to say, in the present embodiment, when the first condition is satisfied, the air supply side control unit 40 determines the control value to be output based on the first processed data in order to execute the first operation mode and outputs it. In other words, when the first condition is satisfied, the air supply side control unit 40 outputs a control value of the air supply fan 30 different from the control value corresponding to the wind data acquired by the acquisition unit c1.

[0210] In the second automatic operation mode, the air supply side control unit 40 determines whether the third condition is satisfied. If the result is that the third condition is satisfied, the operation mode is switched from the third operation mode to the fourth operation mode. Here, the third condition means that the state where the wind speed value of the wind speed data received by the air supply side communication unit 17 exceeds the upper limit wind speed set by the user continues for a specified time or more. That is, in the present embodiment, when the third condition is satisfied, in order to execute the fourth operation mode, the air supply side control unit 40 determines the control value to be output based on the second processed data and outputs it. In other words, when the third condition is satisfied, the air supply side control unit 40 outputs a control value of the air supply fan 30 that is different from the control value corresponding to the wind data acquired by the acquisition unit c1.

[0211] It should be noted that in the present embodiment, the determination processes of the first condition to the fourth condition are executed by the air supply side control unit 40, but may also be executed by the sensor side control unit 54. In this case, the result information of the determination process performed by the sensor side control unit 54 is transmitted to the air supply device 10.

[0212] (5) Features (5-1) The air volume adjustment device A of the present embodiment includes a control unit C that outputs a control value of the air supply fan 30. The control unit C acquires wind data about the wind acquired at a distance and outputs a control value different from the control value corresponding to the acquired wind data.

[0213] In the present embodiment, the control unit C outputs a control value of the air supply fan 30 that is different from the control value corresponding to the acquired wind data. As a result, the wind adjusted from the wind at a distance is blown out from the air supply fan 30. Therefore, it is possible to reproduce the wind in the natural environment without impairing the comfort of the people in the target space S.

[0214] (5-2) The control unit C of the present embodiment generates processed data obtained by processing the wind data and determines the control value to be output based on the processed data. In the present embodiment, the control unit C is used to generate processed data obtained by processing the wind data, and the control value to be output is determined based on the processed data. As a result, the wind adjusted from the wind at a distance can be blown out from the air supply fan 30.

[0215] (5-3) The control unit C of the present embodiment outputs a control value that shows the same tendency as the increase or decrease tendency of the wind speed in the wind data. In the present embodiment, the control value output by the control unit C shows the same tendency as the increase or decrease tendency of the wind speed in the wind data. Therefore, it is possible to reproduce the wind with the same fluctuation as the wind at a distance in the target space S.

[0216] (5-4) The control unit C of the present embodiment outputs a control value such that the average wind speed of the air blown out from the air supply fan 30 reaches the average wind speed arbitrarily set by the user. In the present embodiment, the control value output by the control unit C is a control value such that the average wind speed of the air blown out from the air supply fan 30 reaches the average wind speed arbitrarily set by the user. Therefore, a wind with an intensity freely set by the user and the same fluctuation as the wind in the distance is reproduced in the target space S.

[0217] (5-5) When the state where the wind speed value of the wind data exceeds the upper limit value of the rotation speed of the air supply fan 30 continues for a predetermined time or more, the control unit C of the present embodiment outputs a control value different from the control value corresponding to the acquired wind data.

[0218] If the state where the wind speed value of the acquired wind data exceeds the upper limit value of the rotation speed of the air supply fan 30 continues for a certain period of time, the wind speed of the air blown out from the air supply fan 30 will be constant at the upper limit value of the rotation speed of the fan 30, and the fluctuation of the wind in the distance will not be reproduced. Thus, in the present embodiment, in this state, by outputting a control value different from the control value corresponding to the acquired wind data, the fluctuation of the wind in the distance can be reproduced in the target space S.

[0219] (5-6) When the state where the wind speed value of the wind data exceeds the upper limit wind speed arbitrarily set by the user in advance continues for a predetermined time or more, the control unit C of the present embodiment outputs a control value different from the control value corresponding to the acquired wind data.

[0220] If the state where the wind speed value of the acquired wind data exceeds the upper limit wind speed arbitrarily set by the user in advance continues for a certain period of time, the wind speed of the air blown out from the air supply fan 30 will be constant at the set upper limit wind speed, and the fluctuation of the wind in the distance will not be reproduced. Thus, in the present embodiment, in this state, by outputting a control value different from the control value corresponding to the acquired wind data, the fluctuation of the wind in the distance can be reproduced in the target space S.

[0221] (5-7) The air supply system 1 of the present embodiment includes an air volume adjustment device A. Therefore, an air supply system can be provided that can reproduce the wind in the natural environment without impairing the comfort of people in the target space S.

[0222] (6) Modification example The above embodiment can also adopt the following modification examples. It should be noted that in the following description, the differences from the above embodiment are mainly described in principle.

[0223] (6-1) Variant Example 1 In the air volume adjustment device A of the above-described embodiment, the data processing unit c3 may also generate processed data by multiplying the original data, which is data based on wind data, by a prescribed value. Specifically, in this variant example, the first processed data and the second processed data are generated by multiplying each wind speed value of the original data by a prescribed coefficient.

[0224] In this case, if it is desired to reproduce wind weaker than the original data, the coefficient multiplied by the original data is set to a value less than 1; if it is desired to reproduce wind stronger than the original data, the coefficient multiplied by the original data is set to a value greater than 1.

[0225] In this way, since the first processed data and the second processed data are generated by multiplying each wind speed value of the original data by a prescribed coefficient, the first processed data and the second processed data show the same tendency as the increase and decrease tendency of the wind speed in the original data. In short, the first processed data and the second processed data are data in which the intensity of the wind is changed relative to the original data but the increase and decrease tendency of the wind speed is maintained. Since the control value determination unit c4 determines the control value to be output based on such first processed data or second processed data, a control value showing the same tendency as the increase and decrease tendency of the wind speed in the original data is output from the output determination unit c2.

[0226] In this variant example, by using the data processing unit c3 of the control unit C to multiply the original data by a prescribed value to adjust the control value of the air supply fan 30, the intensity of the wind blown out from the air supply fan 30 is adjusted. As a result, in the target space S, wind whose intensity is changed relative to the wind in the distance and whose fluctuation is the same as the fluctuation of the wind in the distance is reproduced. The prescribed coefficient here is different from that in the above-described embodiment and includes coefficients other than the coefficient converted into the average wind speed desired by the user.

[0227] (6-2) Variant Example 2 In the air volume adjustment device A of the above-described embodiment, the data processing unit c3 may also generate processed data by multiplying the original data, which is data based on wind data, by a prescribed value corresponding to the wind speed value. Specifically, in this variant example, the first processed data and the second processed data are generated by multiplying each wind speed value of the original data by the prescribed coefficient recorded in the Figure 23 table shown. The table recording the prescribed coefficient is stored in advance in the air supply side storage unit 18.

[0228] Figure 23 The table shown is a table recording the wind speed value and the coefficient corresponding to the wind speed value. As Figure 23As shown, for example, when the wind speed value is A, the value obtained by multiplying the wind speed value by 0.7 is generated as the processed data. When the wind speed value is B, the value obtained by multiplying the wind speed value by 1.0 is generated as the processed data. When the wind speed value is C, the value obtained by multiplying the wind speed value by 1.15 is generated as the processed data. It should be noted that in this table, the specific values of the wind speed values A, B, and C are recorded. The value of the wind speed value A is the largest, the wind speed value B is less than the wind speed value A, and the wind speed value C is less than the wind speed value B (A > B > C). In other words, in this table, the faster the wind speed, the smaller the corresponding coefficient is set.

[0229] In this table, the wind speed values A to C can also be recorded as values with a range. For example, in this table, it can also be that when the wind speed value x of the original data is above a1 and below a2 (a1 ≤ x ≤ a2), the corresponding coefficient is 0.7. The table for generating the first processed data and the table for generating the second processed data can be the same or different.

[0230] In this way, since the first processed data and the second processed data are generated by multiplying each wind speed value of the original data by a specified coefficient, the first processed data and the second processed data show the same tendency as the increase and decrease tendency of the wind speed in the original data. In short, the first processed data and the second processed data are data that change the wind intensity relative to the original data but maintain the increase and decrease tendency of the wind speed. Since the control value determination unit c4 determines the control value to be output based on such first processed data or second processed data, a control value showing the same tendency as the increase and decrease tendency of the wind speed in the original data is output from the output determination unit c2.

[0231] In this modified example as well: By using the data processing unit c3 of the control unit C to multiply the original data by a specified value to adjust the control value of the air supply fan 30, the intensity of the wind blown from the air supply fan 30 is adjusted. Thus, in the target space S, a wind with a changed intensity and the same fluctuation as the wind in the distance is reproduced.

[0232] (6-3) Modified Example 3 In the air volume adjustment device A of the above embodiment, the data processing unit c3 can also generate processed data by operating a specified function on the original data, and the above original data is used as data based on wind data. Specifically, in this modified example, the processed data is generated based on the specified function f(x). Here, the input value x is the wind speed value of the original data. The specified function f(x) is pre-stored in the air supply side storage unit 18. The function for generating the first processed data and the function for generating the second processed data can be the same or different.

[0233] The specified function f(x) is a function that calculates a value for maintaining the increasing or decreasing tendency of the wind speed in the original data. Therefore, in this modified example, the first processed data and the second processed data also show the same tendency as the increasing or decreasing tendency of the wind speed in the original data. In short, the first processed data and the second processed data are data that have changed the wind intensity relative to the original data but maintained the increasing or decreasing tendency of the wind speed. Since the control value determination unit c4 determines the control value to be output based on such first processed data or second processed data, the control value output from the output determination unit c2 shows the same tendency as the increasing or decreasing tendency of the wind speed in the original data.

[0234] In this modified example, the control unit C uses a function specified for data operation based on wind data. Thereby, the control value of the air supply fan 30 is adjusted, so that the intensity of the wind blown out from the air supply fan 30 is adjusted, and a wind with a changed intensity and the same fluctuation as that of the wind in the distance is reproduced in the target space S.

[0235] 《Fourth Embodiment》 The fourth embodiment will be described. In the air supply system 1 of this embodiment, the air volume adjustment device A is not included in the air supply device 10 but is included in the sensor unit 50, which is different from the air supply system 1 of the third embodiment. Here, the differences between the air supply system 1 of this embodiment and the air supply system 1 of the third embodiment will be described.

[0236] (1) Air supply system As Figure 24 shown, in the air supply system 1 of this embodiment, the air volume adjustment device A is included in the sensor unit 50. In other words, the air volume adjustment device A of this embodiment constitutes a part of the sensor unit 50.

[0237] The sensor side control unit 54 of the sensor unit 50 has an acquisition unit c1 and an output determination unit c2 as functional elements. In other words, the sensor side control unit 54 functions as the acquisition unit c1 and the output determination unit c2 by executing a program stored in the storage device.

[0238] Here, the sensor side control unit 54 of this embodiment corresponds to the control unit C of the air volume adjustment device A of the present disclosure. The acquisition unit c1 and the output determination unit c2 of the sensor side control unit 54 are the same as those of the third embodiment.

[0239] The air supply side control unit 40 of the air supply device 10 in this embodiment is the same as the air supply side control unit 40 of the third embodiment after removing the acquisition unit c1 and the output determination unit c2.

[0240] (2) Operating action In the air supply system 1 of the present embodiment, the same multiple operation modes as those in the third embodiment are executed. The content of each operation mode is the same as that in the first embodiment. In addition, the "operation mode determination process" and the "switching operation between the first automatic operation mode and the second automatic operation mode" in the present embodiment are the same as those in the third embodiment.

[0241] (2-1) Operations of the first operation mode and the fourth operation mode Next, the operation of the first operation mode of the present embodiment will be described. As Figure 25 shown, compared with the first operation mode of the third embodiment, the first operation mode of the present embodiment adds a communication process between the air supply device 10 and the sensor unit 50.

[0242] Specifically, in the operation mode determination process, if the operation mode to be executed is determined to be the first operation mode, the air supply side control unit 40 executes step ST421. In step ST421, the air supply side communication unit 17 sends a signal requesting the control value required in the first operation mode to the sensor unit 50.

[0243] Next, when the sensor side communication unit 52 receives the signal sent in step ST421, the sensor side control unit 54 executes step ST422. In step ST422, the same process as step ST322 of the third embodiment is executed.

[0244] Next, the sensor side control unit 54 executes step ST423 and step ST424. In step ST423 and step ST424, the same processes as step ST323 and step ST324 of the third embodiment are executed.

[0245] Next, the sensor side control unit 54 executes step ST425. In step ST425, the sensor side communication unit 52 sends the control value output by the sensor side control unit 54 to the air supply device 10.

[0246] Next, the air supply side control unit 40 executes step ST426. In step ST426, the same process as step ST325 of the third embodiment is executed. Thus, the wind in the distance is adjusted to an average wind speed arbitrarily set by the user, and the adjusted wind is used to reproduce the wind in the distance. Therefore, it is possible to reproduce the wind in the distance without impairing the comfort of the people in the target space S.

[0247] The air supply side control unit 40 stops the first operation mode at the end of step ST426. The air supply side control unit 40 may also execute step ST421 again after the end of step ST426. In this case, the air supply side control unit 40 continues to execute the operations of the first operation mode until an instruction to stop the operation of the air supply device 10 or an instruction to change the operation mode of the air supply device 10 to another operation mode is input to the input unit 19.

[0248] In the fourth operation mode of the present embodiment, the sensor side control unit 54 and the air supply side control unit 40 perform the same operation processing as the first operation mode. In the fourth operation mode, second processed data is generated in step ST423.

[0249] (2-2) Operations of the second operation mode and the third operation mode Next, the operations of the second operation mode of the present embodiment will be described. As Figure 26 shown, in the second operation mode, step ST423 is not executed as compared with the first operation mode.

[0250] Specifically, steps ST431 to ST435 of the second operation mode are the same as steps ST421, ST422, ST424 to ST426 of the first operation mode, respectively. It should be noted that in step ST433 of the second operation mode, the air supply side control unit 40 determines the control value to be output based on the acquired unprocessed data. Thus, the control value of the air supply fan 30 corresponding to the unprocessed data is determined and output. As a result, in the second operation mode, the wind in the distance is reproduced in such a way that the average wind speed arbitrarily set by the user is adjusted. Therefore, it is possible to reproduce the wind in the distance without impairing the comfort of the people in the target space S.

[0251] In the third operation mode of the present embodiment, the sensor side control unit 54 and the air supply side control unit 40 perform the same operation processing as the second operation mode.

[0252] (3) Features The present embodiment also has the same features as the third embodiment. Specifically, in the present embodiment, by causing the control unit C of the air volume adjustment device A to output a control value of the air supply fan 30 different from the control value corresponding to the acquired wind data, the wind obtained by adjusting the wind in the distance is blown out from the air supply fan 30. Therefore, it is possible to reproduce the wind in the natural environment without impairing the comfort of the people in the target space S.

[0253] (4) Modification examples In the air volume adjustment device A of the above-described embodiment, the modification examples 1 to 3 of the third embodiment can also be applied. As a result, the same operational effects as those of the modification examples 1 to 3 of the third embodiment can also be obtained in the above-described embodiment.

[0254] 《Fifth Embodiment》 The fifth embodiment will be described. In the air supply system 1 of the present embodiment, the air volume adjustment device A is not included in the air supply device 10 but is included in the server device 60, which is different from the air supply system 1 of the third embodiment. Here, the differences between the air supply system 1 of the present embodiment and the air supply system 1 of the third embodiment will be described.

[0255] (1) Air Supply System As Figure 27 shown, the air supply system 1 of the present embodiment includes one air supply device 10, one sensor unit 50, and one server device 60. The air volume adjustment device A of the present embodiment is included in the server device 60. In other words, the air volume adjustment device A of the present embodiment constitutes a part of the server device 60.

[0256] (2) Server Device The server device 60 has a server-side communication unit 61, a server-side storage unit 62, and a server-side control unit 63.

[0257] The server-side communication unit 61 is communicably connected to the sensor unit 50 and the air supply device 10 via a communication line 45 such as the Internet. The server-side communication unit 61 has a function as a transmission unit for transmitting signals and a function as a reception unit for receiving signals.

[0258] The server-side storage unit 62 stores the detection values of the sensor 51 transmitted from the sensor unit 50. The sensor-side storage unit 53 has the same structure as the storage unit 18 of the first embodiment. The server-side control unit 63 has the same structure as the control unit 40 of the first embodiment. The server-side control unit 63 has an acquisition unit c1 and an output determination unit c2 as functional elements. In other words, the server-side control unit 63 functions as the acquisition unit c1 and the output determination unit c2 by executing a program stored in a storage device.

[0259] Here, the server-side control unit 63 of the present embodiment corresponds to the control unit C of the air volume adjustment device A of the present disclosure. The acquisition unit c1 and the output determination unit c2 of the server-side control unit 63 are the same as those of the third embodiment.

[0260] The air supply device 10 of the present embodiment is the same as the air supply device 10 of the fourth embodiment. The sensor unit 50 of the present embodiment is the same as the sensor unit 50 of the third embodiment.

[0261] (2) Operating action In the air supply system 1 of the present embodiment, the same multiple operating modes as those of the third embodiment are executed. The content of each operating mode is the same as that of the first embodiment. In addition, the "determination process of the operating mode" and the "switching action between the first automatic operating mode and the second automatic operating mode" of the present embodiment are the same as those of the third embodiment.

[0262] The actions of the first operating mode and the fourth operating mode of the present embodiment are the actions after replacing the sensor unit 50 with the server device 60, replacing the sensor-side communication unit 52 with the server-side communication unit 61, replacing the sensor-side control unit 54 with the server-side control unit 63, and replacing the sensor-side storage unit 53 with the server-side control unit 63 in (2-1) of the fourth embodiment. In addition, the actions of the second operating mode and the third operating mode of the present embodiment are the actions after performing the same replacements as those of the actions of the first operating mode and the fourth operating mode described above in (2-2) of the fourth embodiment.

[0263] (3) Features The present embodiment also has the same features as those of the third embodiment. Specifically, in the present embodiment, by making the control unit C of the air volume adjustment device A output a control value of the air supply fan 30 different from the control value corresponding to the acquired wind data, the wind adjusted from the wind in the distance is blown out from the air supply fan 30. Therefore, it is possible to reproduce the wind in the natural environment without impairing the comfort of the people in the target space S.

[0264] (4) Variants In the air volume adjustment device A of the above embodiment, the variants 1 to 3 of the third embodiment can also be applied. As a result, the same effects as those of the variants 1 to 3 of the third embodiment can also be obtained in the above embodiment.

[0265] 《Sixth Embodiment》 The sixth embodiment will be described. The air supply system 1 of the present embodiment is obtained by changing the structure of the air supply side control unit 40 in the air supply system 1 of the third embodiment. Here, the differences between the air supply system 1 of the present embodiment and the air supply system 1 of the third embodiment will be described.

[0266] (1) Air supply device As Figure 28 shown, in the air supply device 10 of the present embodiment, the air supply side control unit 40 has an output determination unit c2 as a functional element, and the output determination unit c2 has a control value determination unit c4 and a correction unit c5.

[0267] The control value determination unit c4 determines the control value of the air supply fan 30 corresponding to the wind data. The control value determination unit c4 of the present embodiment determines the control value corresponding to the original data. The "control value corresponding to the original data" mentioned here refers to: the control value of the air supply fan 30 that reproduces the wind of the acquired wind speed data as it is.

[0268] The correction unit c5 corrects the control value determined by the control value determination unit c4. In addition, the correction unit c5 determines the corrected control value as the control value to be output and outputs it.

[0269] In this way, in the present embodiment, since the control value of the air supply fan 30 is corrected by the correction unit c5, the control value of the air supply fan 30 different from the control value corresponding to the acquired wind data is output from the output determination unit c2. In other words, in the output determination unit c2 of the present embodiment, the control value of the air supply fan 30 is changed without processing the acquired wind data, and the control value of the air supply fan 30 different from the control value corresponding to the acquired wind data is output.

[0270] The correction unit c5 corrects the control value so that the average wind speed value of the air blown out from the air supply fan 30 reaches the average wind speed value arbitrarily set by the user. Specifically, in the present embodiment, correction data is generated by multiplying the data of the control value determined by the control value determination unit c4 by a prescribed coefficient. The data of the control value determined by the control value determination unit c4 is data based on the wind data. In the correction unit c5, first correction data used in the first operation mode and second correction data used in the fourth operation mode are generated.

[0271] The first correction data and the second correction data are data corrected so that the average wind speed value of the air blown out from the air supply fan 30 reaches the average wind speed value arbitrarily set by the user. Therefore, the first correction data and the second correction data show the same tendency as the increase and decrease tendency of the wind speed in the original data. All in all, the first correction data and the second correction data are data that change the wind intensity but maintain the increase and decrease tendency of the wind speed with respect to the original data. Since the correction unit c5 determines such first correction data or second correction data as the control value to be output and outputs it, the control value showing the same tendency as the increase and decrease tendency of the wind speed in the original data is output from the output determination unit c2.

[0272] (4) Operating actions In the air supply system 1 of the present embodiment, the same multiple operation modes as those of the third embodiment are executed. The content of each operation mode is the same as that of the first embodiment. In addition, the "determination process of the operation mode" and the "switching actions of the first automatic operation mode and the second automatic operation mode" in the present embodiment are the same as those of the third embodiment.

[0273] (4-1) Operations of the first operation mode and the fourth operation mode Next, the operation of the first operation mode of the present embodiment will be described. As Figure 29 shown, in the first operation mode of the present embodiment, the process of determining the output is different from that of the first operation mode of the third embodiment.

[0274] Specifically, in the operation mode determination process, if the operation mode to be executed is determined to be the first operation mode, the air supply side control unit 40 executes step ST621 and step ST622. In step ST621 and step ST622, the same processes as step ST321 and step ST322 of the third embodiment are respectively executed.

[0275] Next, the air supply side control unit 40 executes step ST623. In step ST623, the air supply side control unit 40 determines the control value of the air supply fan 30 corresponding to the original data.

[0276] Next, the air supply side control unit 40 executes step ST624. In step ST624, the air supply side control unit 40 corrects the control value determined by the control value determination unit c4 to generate first correction data. Then, the air supply side control unit 40 determines the first correction data as the control value to be output and outputs it. Specifically, in step ST624, the first correction data is generated by multiplying the data of the control value determined in step ST623 by a prescribed coefficient γ. The prescribed coefficient γ is a coefficient for converting the data of the control value determined in step ST623 so that the average wind speed of the air blown out from the air supply fan 30 reaches the average wind speed arbitrarily set by the user.

[0277] Next, the air supply side control unit 40 executes step ST625. In step ST625, the same process as step ST325 of the third embodiment is executed. As a result, the wind in the distance is adjusted to the average wind speed arbitrarily set by the user, and the wind in the distance is reproduced using the adjusted wind. Therefore, it is possible to reproduce the wind in the distance without impairing the comfort of the people in the target space S. It should be noted that in the first operation mode, the upper limit wind speed of the air supply fan 30 is the maximum wind speed of the air supply fan 30. Therefore, in the first operation mode, in the region where the first correction data exceeds the maximum wind speed of the air supply fan 30, the air supply fan 30 blows out the air at the maximum wind speed of the air supply fan 30.

[0278] In the fourth operation mode of the present embodiment, the air supply side control unit 40 performs the same operation process as in the first operation mode. As described above, in step ST624 of the first operation mode, first correction data is generated, and in step ST624 of the fourth operation mode, second correction data is generated. Specifically, in step ST624 of the fourth operation mode, the second correction data is generated by multiplying the data of the control value determined in step ST623 by a predetermined coefficient δ. The predetermined coefficient δ is a coefficient for converting the data of the control value determined in step ST623 so that the average wind speed of the air blown out from the air supply fan 30 reaches the average wind speed arbitrarily set by the user.

[0279] In addition, in step ST625 of the first operation mode, the upper limit wind speed of the air supply fan 30 is the maximum wind speed of the air supply fan 30, while in step ST625 of the fourth operation mode, the upper limit wind speed of the air supply fan 30 is the upper limit wind speed arbitrarily set by the user. Therefore, in the fourth operation mode, in the region where the second correction data exceeds the set upper limit wind speed, the air of the set upper limit wind speed is blown out from the air supply fan 30.

[0280] (4-2) Operations of the second operation mode and the third operation mode Next, the operation of the second operation mode of the present embodiment will be described. As Figure 30 shown, in the second operation mode, compared with the first operation mode, step ST624 is not executed.

[0281] Specifically, steps ST631 to ST634 of the second operation mode are the same as steps ST621 to ST623 and ST625 of the first operation mode respectively. It should be noted that in step ST633 of the second operation mode, the air supply side control unit 40 determines the control value of the air supply fan 30 corresponding to the original data. Specifically, the air supply side control unit 40 determines the control value to be output based on the acquired wind speed data, which is the unprocessed data as it is. Thus, the control value of the air supply fan 30 corresponding to the unprocessed data is determined and output. As a result, in the second operation mode, the distant wind is reproduced as it is in the target space S.

[0282] In the third operation mode of the present embodiment, the air supply side control unit 40 performs the same operation process as in the second operation mode. In step ST634 of the second operation mode, the upper limit wind speed of the air supply fan 30 is the maximum wind speed of the air supply fan 30, while in step ST634 of the third operation mode, the upper limit wind speed of the air supply fan 30 is the upper limit wind speed arbitrarily set by the user. Therefore, in the third operation mode, in the region where the unprocessed data exceeds the set upper limit wind speed, the air of the upper limit wind speed is blown out from the air supply fan 30.

[0283] (5) Feature In this embodiment, the control unit C of the air volume adjustment device A determines a control value corresponding to the wind data, corrects the determined control value, and determines the corrected value as the control value to be output. Thus, the air supply fan 30 can blow out the air after adjusting the air in the distance.

[0284] (6) Modification The air volume adjustment device A of the above embodiment may also be included in the sensor unit 50 or the server device 60 as in the fourth and fifth embodiments. In the air volume adjustment device A of the above embodiment, the modifications of the third to fifth embodiments can also be applied. As a result, the same effects as those of the third to fifth embodiments and their modifications can also be obtained in the above embodiment.

[0285] 《Seventh Embodiment》 The seventh embodiment will be described. The air supply system 1 of this embodiment is obtained by adding a judgment unit to the air supply side control unit 40 in the air supply system 1 of the third embodiment. Here, the differences between the air supply system 1 of this embodiment and the air supply system 1 of the third embodiment will be described.

[0286] (1) Air supply device In this embodiment, the air supply control unit C of the air supply device 10 is obtained by adding a judgment unit as a functional element to the air supply side control unit 40 of the third embodiment. The judgment unit judges whether the fifth condition is satisfied. The fifth condition refers to the state where the wind speed value (raw data) of the wind data is below a specified reference value for a specified period of time. The specified reference value here is a very small wind speed value. When the fifth condition is satisfied, it can be considered that the distance is in a state of blowing a very weak breeze or no wind.

[0287] In this embodiment, the judgment unit judges whether the state where the average wind speed value included in a set of wind data received from the sensor unit 50 is below a specified reference value continues for a specified period of time. The judgment unit may also judge whether the state where the maximum value of the wind speed values included in a set of wind data is below a specified reference value continues for a specified period of time. In other words, in this embodiment, the judgment unit makes a judgment based on a set of wind data transmitted from the sensor unit 50.

[0288] In the present embodiment, if the fifth condition is satisfied, the data processing unit c3 of the output determination unit c2 processes the original data to generate third processed data. The third processed data is data obtained by magnifying the wind speed value of the original data, and the original data is used as data based on wind data. The data processing unit c3 generates the third processed data by multiplying the original data by a predetermined coefficient. The data processing unit c3 may also generate the third processed data by adding a predetermined value to the original data.

[0289] In the present embodiment, the determination process of the determination unit is executed during the execution of all the operation modes among the plurality of operation modes. Therefore, when any one of the operation modes is being executed, if the fifth condition is satisfied, the data processing unit c3 generates the third processed data and controls the air supply fan 30 based on the third processed data.

[0290] (2) Features In the present embodiment, when the state where the wind speed value of the wind data is below a predetermined reference value continues for a predetermined time or more, the control unit C of the air volume adjustment device A magnifies the data based on the wind data. When the wind speed value of the wind data acquired by the control unit C is below the predetermined reference value, a very weak wind is blowing in the distance. If this weak wind continues for a certain period of time, the people in the target space S will not be able to feel the wind because the wind blown from the air supply fan 30 is very weak. Thus, in the present embodiment, in such a state, by magnifying the original data by the control unit C, the people in the target space S can continuously receive the reproduced wind in the distance.

[0291] (3) Variation The above embodiment may also adopt the following variation. It should be noted that in the following description, the differences from the above embodiment will be described in principle.

[0292] (3-1) Variation 1 In the air volume adjustment device A of the above embodiment, it may also be configured that: when the state where the wind speed value of the wind data is below a predetermined reference value continues for a predetermined time or more, the control value to be output is determined based on substitute data.

[0293] Specifically, the air supply side storage unit 18 stores substitute data regarding wind in advance. In this variation, the air supply side storage unit 18 corresponds to the storage unit of the present disclosure. The substitute data is data different from the wind data received from the sensor unit 50 in real time. The substitute data may be wind data received from the sensor unit 50 in the past and stored in the air supply side storage unit 18, or may be wind data stored in the air supply side storage unit 18 when the air supply device 10 is manufactured.

[0294] When the determination unit determines that the fifth condition is satisfied, the control value determination unit c4 of the air supply side control unit 40 determines the control value of the air supply fan 30 to be output based on the substitute data. In this case, a control value different from the control value corresponding to the wind data acquired by the acquisition unit c1 is output from the output determination unit c2.

[0295] In the present embodiment, when the state where the wind speed value of the wind data is below a specified reference value continues for a specified time or more, the control unit C determines the control value to be output based on the substitute data. Therefore, when it is in a state of having a gentle breeze or no wind in the distance, by determining the control value to be output based on the substitute data, people in the target space S can continuously receive the reproduced wind from the distance.

[0296] (3-2) Variant 2 The air volume adjustment device A of the above-described embodiment may also be included in the sensor unit 50 or the server device 60 as in the fourth and fifth embodiments. In the air volume adjustment device A of the above-described embodiment, the variants of the third to fifth embodiments can also be applied. As a result, the same operational effects as those of the third to fifth embodiments and their variants can also be obtained in the above-described embodiment.

[0297] In addition, the air volume adjustment device A of the above-described embodiment may also be such that the output determination unit c2 has a control value determination unit c4 and a correction unit c5 as in the sixth embodiment. In this case, the same operational effects as those of the sixth embodiment and its variants can also be obtained in the above-described embodiment.

[0298] (3-3) Variant 3 In the above-described embodiment, the air supply side control unit 40 has a determination unit, and the determination process of the fifth condition is executed by the air supply side control unit 40, but the determination unit may also be included in the sensor side control unit 54 or the server side control unit 63.

[0299] 《Eighth Embodiment》 The eighth embodiment will be described. The air supply system 1 of the present embodiment is obtained by adding a sound generation unit 20 to the air supply system 1 of the third embodiment. Here, the differences between the air supply system 1 of the present embodiment and the air supply system 1 of the third embodiment will be described.

[0300] (1) Sound generation unit The air supply device 10 of the present embodiment includes a sound generation unit 20. The sound generation unit 20 of the present embodiment is the same as that of the second embodiment. In the present embodiment, the air supply side control unit 40 outputs a signal for generating a sound simulating a natural environment based on the original data which is data based on wind data. Specifically, the air supply side control unit 40 adjusts the volume of the sound (for example, the sound of wind blowing) generated from the sound generation unit 20 based on the original data. In detail, similarly to the second embodiment, the air supply side control unit 40 changes the volume as shown in Figure 17 shown.

[0301] In the present embodiment, since the control unit C outputs a signal corresponding to the data based on wind data for generating a sound simulating a natural environment, a sound simulating a natural environment is emitted from the sound generating device.

[0302] (2) Modification In the air volume adjustment device A of the above embodiment, the modification of the second embodiment can also be applied. As a result, the same effects as those of the modification of the second embodiment can also be obtained in the above embodiment.

[0303] In the air volume adjustment device A of the above embodiment, the fourth to seventh embodiments and their modifications can also be applied. As a result, the same effects as those of the fourth to seventh embodiments and their modifications can also be obtained in the above embodiment.

[0304] 《Other Embodiments》 The above embodiments and their modifications may also adopt the following structure.

[0305] The air supply device 10 of the above embodiments etc. may also be included in an air conditioner. In this case, the air conditioner includes the air supply device 10 and a heat exchanger that exchanges heat between the supply air sucked into the air supply device 10 and a heat medium to adjust the temperature of the supply air. The air conditioner blows out the supply air whose temperature has been adjusted when passing through the heat exchanger by using the air supply device 10.

[0306] In the air supply device 10 of the above embodiments etc., a so-called ionic wind element may be provided on the main body portion 15. The ionic wind element is an element configured to generate plasma by discharging and use the generated plasma to generate wind.

[0307] In the air supply system 1 of the above embodiments etc., the storage unit 18 may also be provided in a place other than the air supply device 10. For example, the storage unit 18 may be provided in a server device connected to the communication line 45.

However, it should be understood that various changes can be made to the embodiments or details without departing from the gist and scope of the claims. In addition, the elements involved in the above embodiments, modification examples, and other embodiments can be appropriately combined or replaced.
