Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of a louver system 1 and a building 2 to which the louver device 20 according to the embodiment of the present invention is applied.

The louver system 1 controls the amount of shortwave radiation from the sun (thick arrow in FIG. 1) into the building 2, and also controls the amount of longwave radiation emitted from an object such as the outer wall of the building 2 or a person 5 (Fig. 1). It is a facility (opening device) that realizes a comfortable indoor space by controlling the amount of radiation of the one-dot chain line arrow in 1) to the outside of the building 2.

From the viewpoint of efficiently realizing a comfortable space, the building 2 in which the louver system 1 is installed is preferably made of a highly heat-insulating and highly airtight material for its outer wall and roof, and there is no partition in the room. It is preferably an integrated space.

<Overall configuration of louver system>
Next, an example of the overall configuration of the louver system 1 will be described. As shown in FIG. 1, the louver system 1 includes a louver device 20, an exhaust fan 11, an air supply unit 12, a first temperature sensor 13, a second temperature sensor 14, and a control device 50.

The louver device 20 is arranged at a position corresponding to the window 4 formed on the roof 3. The window 4 is a FIX window made of, for example, tempered glass. The louver device 20 of the present embodiment is arranged on the indoor side of the window 4, but the louver device 20 may be outside the window 4.

Here, the configuration of the louver device 20 will be described with reference to FIG. The louver device 20 includes a plurality of blade plates 30 arranged at predetermined intervals, and a motor 21 for applying a driving force for rotating the blade plates 30. The plurality of blade plates 30 are connected by a link mechanism (not shown) so as to rotate in the same direction and at the same rotation angle by driving the motor 21.

The appearance of the feather plate 30 is formed in the shape of an elongated plate. The light (short wave) from the sun entering the inside of the building 2 from the window 4 by rotating the plane portion of the wing plate 30 to the closed position (the position shown by the broken line in FIG. 2) along the slope of the roof 3 of the building 2. Radiation) can be reflected to the outside of the building 2. Although the wing plate 30 of the present embodiment is installed in a direction along the roof 3 having a slope, the wing plate 30 may be installed in a direction in which the wing plate 30 is inclined with respect to the roof 3.

The structure of the wing plate 30 will be described. The feather plate 30 includes a metal exterior portion 31 and a heat insulating material 34 filled inside the exterior portion 31. The exterior portion 31 is made of, for example, aluminum metal. Further, both the first mirror surface portion 32, which is one side surface of the exterior portion 31, and the second mirror surface portion 33, which is the other side surface, are mirror-finished so as to have high reflectance and roughened so as to be scattered and reflected. Has been done.

When the wing plate 30 is located at the position shown in FIG. 2, the sunlight from the outside of the building 2 is reflected by the first mirror surface portion 32 of the wing plate 30, and then the second mirror surface portion 33 of the adjacent wing plate 30. It will be further reflected and reach the room. In the present embodiment, since the first mirror surface portion 32 and the second mirror surface portion 33 are roughened, diffuse reflection is repeated every time reflection is performed, and soft light is spread throughout the room.

Further, a step portion 35 is formed at one end of the exterior portion 31, and a step portion 36 is formed at the other end. At the closed position shown by the broken line in FIG. 2 above, the step portion 35 of a certain feather plate 30 and the step portion 36 of the adjacent blade plate 30 overlap each other, and the gap between the blade plates 30 in the arrangement direction of the blade plates 30 is closed. It has a structure that can be peeled off.

Next, returning to FIG. 1, the exhaust fan 11 and the air supply unit 12 will be described. The exhaust fan 11 and the air supply unit 12 are ventilation devices for exchanging air in the room. The white arrows in FIG. 1 indicate the flow of air.

The air supply unit 12 is composed of pipes that communicate the indoor and outdoor areas of the building 2. A part of the air supply unit 12 is buried in the ground. When the indoor air is discharged to the outside by driving the exhaust fan 11, the outdoor air is supplied to the room through the air supply unit 12. The drive of the exhaust fan 11 is controlled by the control device 50.

Since the air supply unit 12 of the present embodiment is buried in the ground, the temperature of the suction air approaches the underground temperature in the process of passing through the air supply unit 12. Since the underground temperature tends to show a constant temperature throughout the year, the suction air is cooled when the outdoor temperature is higher than the ground temperature, and the suction air is cooled when the outdoor temperature is lower than the ground temperature. Is heated and air is supplied to the room at a constant temperature. Further, by meandering the path of the air supply unit 12 to secure a long distance of the air supply unit 12 in the ground, the temperature of the suction air can be brought closer to the underground temperature. The air supply unit 12 may be configured to arrange a water tank having a large heat capacity in order to increase the efficiency of heat exchange.

The first temperature sensor 13 is arranged at a relatively high position on the roof 3 side of the building 2, and is arranged at a relatively low position on the floor side of the second temperature sensor 14. For example, in order to make the second floor of the building 2 a comfortable environment, the first temperature sensor 13 is arranged on the roof 3 side and the second temperature sensor 14 is arranged near the floor of the second floor. With this arrangement, the temperature of the upper part where relatively warm air tends to stay can be detected by the first temperature sensor 13, and the temperature of the lower part where relatively cold air tends to stay can be detected by the second temperature sensor 14. ..

<Control device configuration>
Next, the control device 50 will be described with reference to FIG. FIG. 3 is a schematic diagram showing the hardware configuration of the louver system 1.

The control device 50 is a computer that executes various controls of the louver system 1. The control device 50 includes a CPU (Central Processing Unit) 51, a ROM (Read Only Memory) 52, a RAM (Random Access Memory) 53, a storage device 54, and a timer 60.

The CPU 51 is a control unit that executes various processes according to the program recorded in the ROM 52 or the program loaded in the RAM 53.

The storage device 54 is composed of a semiconductor memory such as a DRAM (Dynamic Random Access Memory), and stores various data of the louver system 1.

As shown in FIG. 3, various sensors such as the first temperature sensor 13 and the second temperature sensor 14 are electrically connected to the control device 50 by wire or wirelessly, and the louver device 20 to be controlled and the louver device 20 to be controlled. The exhaust fan 11 is electrically connected by wire or wirelessly.

Further, the display unit 80 and the input unit 81 as user interfaces are electrically connected to the control device 50 by wire or wirelessly. The display unit 80 is a display for displaying an image, and may include a speaker or the like for enhancing the sound. The display unit 80 and the input unit 81 may have an integrated display function and an input function like a touch panel, or may be physically independent of a control device 50 such as a tablet or a smartphone. It may be a configuration.

The control device 50 accepts a user's operation via the input unit 81, and controls the angle of the louver device 20's wing plate 30 according to the result of the user's operation (control condition information). The louver device 20 of the present embodiment is configured so that the user can select a plurality of modes in which the method of controlling the angle of the wing plate 30 is different.

Next, the basic control of the louver device 20 of the present embodiment will be described. FIG. 4 is a functional block diagram showing a functional configuration for controlling the feather plate 30 among the functional configurations of the louver device 20 of the present embodiment.

As shown in FIG. 4, the functional configuration in the present embodiment is realized by the CPU 51 that executes arithmetic processing. In addition to those composed of various processing devices such as single processor, multi-processor and multi-core processor, these various processing devices and processing circuits such as ASIC (Application Specific Integrated Circuit) and FPGA (Field-Programmable Gate Array) are used. The combination of the above may be adopted as a processor to realize a functional configuration.

In the present embodiment, in the CPU 51 as a control unit, the temperature information acquisition unit 61, the time information acquisition unit 62, the solar altitude acquisition unit 63, the angle control unit 64, and the mode setting unit are the parts that execute the control of the blade plate 30. 65, works. The control of the louver device 20 is executed all year round.

The temperature information acquisition unit 61 executes a process of acquiring temperature information that is an index of the indoor environment via the first temperature sensor 13 and the second temperature sensor 14. The temperature information is acquired at predetermined time intervals by using, for example, a timer 60. The temperature information may be the average value of each of the first temperature sensor 13 and the second temperature sensor 14, or any of the detected values of the first temperature sensor 13 and the second temperature sensor 14 is weighted. It may be a value. Further, depending on the case, the detection value of any of the first temperature sensor 13 and the second temperature sensor 14 may be used as the temperature information as it is.

The time information acquisition unit 62 executes a process of acquiring the current time including the date of the area where the building 2 exists. The current time may be acquired from, for example, the timer 60, or may be acquired from the outside by communication.

The solar zenith angle acquisition unit 63 executes a process for acquiring the solar zenith angle at a certain time. The solar zenith angle is information on an angle (elevation angle) measured with the horizon direction as 0 degrees and the zenith (just above the head) as 90 degrees, and is the current position of the sun as seen from the building 2. Since the orbits of the earth's rotation and revolution are constant, the solar altitude can be specified if the latitude, longitude, and time of the current position are known.

The storage device 54 of the present embodiment contains installation information 55 for determining the solar zenith angle, altitude determination information 56 for determining the solar zenith angle from the current position and time, and mode information 57 which is information related to each mode described later. It is remembered.

The installation information 55 is information indicating the state of the installation position of the louver device 20. The installation information 55 includes, for example, latitude / longitude information indicating the installation point of the louver device 20 on the earth, the direction (direction) of the louver device 20 at the installation location, and the inclination of the louver device 20 (installation location such as the window 4 of the roof 3). Installation position information indicating (gradient of) is included. Further, the installation information 55 may include the size of the louver device 20 at the installation location, the size of the installation location, and the like.

The altitude determination information 56 includes, for example, information such as a table for determining the solar altitude based on the latitude / longitude and the current time, or a predetermined calculation formula. The louver installation information 55 is reflected in this table and the calculation formula. The control device 50 of the present embodiment can independently calculate the solar zenith angle information without communicating with the outside.

The mode information 57 includes, for example, information such as the name of the mode displayed on the display unit 80, the method for controlling the angle of the wing plate 30 set for each mode, and the like.

The angle control unit 64 executes a process for controlling the angle of the blade plate 30. The angle of the wing plate 30 here is, for example, an inclination with respect to the slope of the roof 3 (window 4) in which the louver device 20 is arranged in the building 2.

The mode setting unit 65 executes a process of setting an angle control method by the angle control unit 64. For example, when the mode setting unit 65 detects that the user has selected a certain mode through the input unit 81, the mode information 57 corresponding to the selected mode is read from the storage device 54, and the mode information 57 is used as an angle control method. Set.

Next, the flow of processing for angle control by the angle control unit 64 will be described with reference to FIG. FIG. 5 is a flowchart showing an example of control of the louver device 20 by the control device 50 of the present embodiment. The flow shown in FIG. 5 is a flow started when the user selects a predetermined mode from the input unit 81.

When the flow of FIG. 5 is started, the mode setting unit 65 executes a process of reading the mode setting of the mode selected by the user from the mode information 57 of the storage device 54 (step S1).

Next, the temperature information acquisition unit 61 executes a process of acquiring indoor temperature information via the first temperature sensor 13 and the second temperature sensor 14 at a preset timing (step S2). The temperature information acquisition unit 61 acquires the current room temperature at regular time intervals (for example, every 10 minutes).

The solar altitude acquisition unit 63 reads out the altitude determination information 56 stored in the storage device 54 based on the time information, and acquires the solar altitude information indicating the current solar altitude of the installation location based on the current position and the current time. (Step S3).

Next, the angle control unit 64 controls the angle of the wing plate 30 so that the room temperature approaches the set temperature based on the temperature information acquired by the temperature information acquisition unit 61 and the solar altitude information acquired by the solar altitude acquisition unit 63. (Step S4). The angle control of the blade 30 by the angle control unit 64 differs depending on the mode. Details of the angle control that differs for each mode will be described later. For example, when the room temperature priority mode is selected and during the daytime, the angle control unit 64 compares the room temperature with the set temperature, and if the room temperature is higher than the set temperature, the wing plate 30 is set at a constant angle (in the direction of lowering the room temperature). For example, the motor 21 is controlled to rotate (5 degrees). On the contrary, if the temperature is lower than the set temperature and lower than the room temperature, the motor 21 is controlled so as to rotate in the opposite direction by a constant angle (eg, 5 degrees). In the present embodiment, the set temperature is a temperature range (for example, 20 ° C to 25 ° C) preset as a comfortable temperature zone.

Next, the mode setting unit 65 determines whether or not the mode end condition is satisfied, and if it is satisfied, ends the process of this mode (step S5: Yes). If the mode end condition is not satisfied in step S5, the process returns to the process of step S2 (step S5: No), and the subsequent processes are repeated. In the present embodiment, the process of approaching the optimum temperature (= set temperature) is executed by repeating the determination of rotating the feather plate 30 in the forward direction or the reverse direction at regular time intervals.

Various conditions can be set for the mode end condition. For example, the time has reached a preset time after the mode reading process by the mode setting unit 65 is executed, or it is determined from the time information that the time has changed from nighttime to daytime or from daytime to nighttime.

As described above, the angle control unit 64 of the present embodiment determines and determines the rotation direction for rotating the feather plate 30 based on the latitude / longitude information, the installation position information, the time information, and the temperature information included in the installation information 55. The process of rotating the feather plate 30 by a preset predetermined angle in the set rotation direction is repeated at preset time intervals. It should be noted that the control may be such that the feather plate 30 is rotated based on a preset schedule instead of a preset time interval.

The functional configuration of FIG. 4 and the flowchart of FIG. 5 described above are merely examples and are not particularly limited. That is, it is sufficient that the control device 50, which is a computer, has a function capable of executing the above-mentioned series of processes as a whole, and what kind of functional block is used to realize this function is not particularly limited. Further, the order of processing each step in the flowchart is not limited to the order shown in FIG.

<Mode selection>
A plurality of modes set by the mode setting unit 65 will be described with reference to FIG. FIG. 6 is a diagram schematically showing a mode selection screen 70 of the louver device 20 of the present embodiment. Note that FIG. 6 is merely an example of an image displayed on the display unit 80, and the means for selecting the mode can be replaced by various methods such as arranging another image example or a dedicated physical button.

As shown in FIG. 6, the louver device 20 has a plurality of modes such as a room temperature priority mode 71, a lighting priority mode 72, a sunny mode 73, a cool night mode 74, and a manual mode 75. The user can select each mode via the input unit 81. When the control device 50 receives that the mode has been selected by the user, the control device 50 changes the control method of the louver device 20 based on the selected mode (control condition information), and sets the louver device 20 based on the changed control method. Control. As described above, in the present embodiment, in order to cause the computer to control the louver device 20 having the feather plate 30, the user sets the control condition information for controlling the angle of the feather plate 30 in advance. Hereinafter, the angle control method for each mode will be described.

<Room temperature priority mode>
First, the room temperature priority mode 71 will be described. The room temperature priority mode 71 is a mode for controlling the position of the feather plate 30 based on a preset set temperature, and is a mode in which the room temperature is given the highest priority. The set temperature can also be adjusted by the user. Further, in the room temperature priority mode 71, the control device 50 also controls the exhaust fan 11.

In the present embodiment, the room temperature priority mode 71 controls differently during the daytime and at night when the sun is shining. First, the daytime control of the room temperature priority mode 71 will be described.

When the room temperature priority mode 71 is set by the mode setting unit 65, the angle control unit 64 determines whether it is during the daytime or after sunset. In the present embodiment, the angle control unit 64 determines whether it is daytime or after sunset based on the solar zenith angle information. For example, if the solar zenith angle Φ satisfies the relationship of Φ> 0, it is determined to be daytime, and if the solar zenith angle Φ is Φ = 0 or 0 ≧ Φ, it is determined to be after sunset. The method for determining whether it is during the daytime or after sunset is not limited to this. The angle control unit 64 may determine whether it is daytime or after sunset based on the time information, or determine whether it is daytime or after sunset based on the information indicating daytime or after sunset transmitted from the outside. You may. When it is determined whether the daytime is after sunset, the angle control unit 64 monitors the temperature information periodically acquired by the temperature information acquisition unit 61, and if the temperature deviates from the set temperature, the angle control unit 64 enters the set temperature. The angle θ of the blade plate 30 is controlled.

A method of controlling the angle θ in the daytime control of the room temperature priority mode 71 will be described with reference to FIG. 7. FIG. 7 is a schematic diagram of a feather plate 30 for explaining daytime control of the room temperature priority mode 71 of the present embodiment. In FIG. 7, the angle θ is the angle θ of the blade 30 with respect to the slope of the roof 3. For example, when θ = 0, it indicates that the flat surface portion of the wing plate 30 has a parallel relationship with the slope of the roof 3 (the position of the broken line in FIG. 2). Further, the angle α indicates the slope of the roof 3 with respect to the horizontal direction, and the angle φ indicates the solar altitude acquired by the solar altitude acquisition unit 63. Further, the chain line in FIG. 7 is a virtual straight line P parallel to the slope of the roof 3.

As shown in FIG. 7, the limit angle θ at which light does not directly enter the room without being reflected by the wing plate 30 is an isosceles triangle when the angle θ is the apex angle (in gray in FIG. 7). It is when the indicated triangle) holds. At this time, assuming that the length of the flat surface portion of the blade plate 30 in the width direction is L, the distance to the adjacent blade plates 30 is also L. The limit angle θ at which light does not directly enter the room can be expressed by the following equation (1).

θ = 180-2 (φ + α) ・ ・ ・ Equation (1)

On the other hand, the limit angle θ of the angle θ into which the reflected light enters can be expressed by the following equation (2).

θ = 90- (φ + α) ・ ・ ・ Equation (2)

Based on the above, the range of the angle θ in the daytime control of the room temperature priority mode 71 can be set as follows. In the daytime control of the room temperature priority mode 71, when the room temperature is higher than the set temperature, the angle of the feather plate 30 with respect to the slope of the roof 3 is rotated by a predetermined angle in a direction that becomes smaller within the angle range shown in the equation (3). When the room temperature is lower than the set temperature, the control of rotating the angle of the feather plate 30 at a predetermined angle in a direction increasing within the angle range shown in the equation (3) is executed. Then, the angle control unit 64 drives the motor 21 of the louver device 20 to control the angle θ of the blade plate 30. For example, the feather plate 30 is rotated by a predetermined angle of 5 degrees in the forward direction (or the reverse direction). At this time, if the angle range is exceeded, the blade 30 is rotated to the limit value of the angle range.

180-2 (φ + α)>θ> 90- (φ + α) ・ ・ ・ Equation (3)

Next, the post-sunset control of the room temperature priority mode 71 will be described with reference to FIG. FIG. 8 is a schematic diagram of a feather plate 30 for explaining post-sunset control of the room temperature priority mode 71 of the present embodiment. The angle range in post-sunset control can be expressed by equation (4) from the viewpoint of enhancing the effect of radiative cooling. As shown in the equation (4), in the daytime control, the angle parallel to the slope of the roof 3 like the wing plate 30a is the minimum angle, and the angle orthogonal to the slope of the roof 3 like the wing plate 30b is the minimum angle. It becomes the maximum angle.

90 ≧ θ ≧ 0 ・ ・ ・ Equation (4)

The mode setting unit 65 determines a method of controlling the angle θ in the post-sunset control of the room temperature priority mode 71 based on the time information including the date acquired by the time information acquisition unit 62.

In the post-sunset control, the rotation direction is set in the opposite direction to the daytime control. That is, in the post-sunset control of the room temperature priority mode 71, when the room temperature is higher than the set temperature, the angle of the feather plate 30 with respect to the slope of the roof 3 becomes larger within the angle range shown in the equation (4) at a predetermined angle. The rotation is performed, and when the room temperature is lower than the set temperature, the control of rotating the blade plate 30 at a predetermined angle in a direction to be smaller within the angle range shown in the equation (4) is executed. Then, the angle control unit 64 drives the motor 21 of the louver device 20 to control the angle θ of the blade plate 30. For example, the feather plate 30 is rotated by a predetermined angle of 5 degrees in the forward direction (or the reverse direction). At this time, if the angle range is exceeded, the blade 30 is rotated to the limit value of the angle range.

In the post-sunset control of the room temperature priority mode 71, when the season is winter, θ often becomes 0 as shown by the wing plate 30a shown by the broken line in FIG. 8, and the window 4 is closed by the louver device 20. Will be. In this state, the temperature drop due to radiative cooling can be prevented, and the room temperature drop in winter can be effectively prevented.

On the other hand, when the season is summer in the control after sunset in the room temperature priority mode 71, the wing plate 30b is rotated to a position where the window 4 is not closed like the wing plate 30b shown by the solid line in FIG. 8 to promote radiative cooling. Controls that promote a decrease in temperature are often performed.

In this way, by making the control of the room temperature priority mode 71 different between daytime and after sunset, a more comfortable indoor environment can be realized.

FIG. 9 is a graph showing the relationship between room temperature and time when the room temperature priority mode is selected in the louver device 20 of the present embodiment for each season. Of these, FIG. 9 (a) is a graph showing the relationship between the time zone and the temperature in the sunny weather in summer, and FIG. 9 (b) is a graph showing the relationship between the time zone and the temperature in the sunny weather in spring and autumn. , FIG. 9 (c) is a graph showing the relationship between the time zone and the temperature in the fine weather in winter.

In any of the graphs of FIGS. 9A to 9C, the solid line indicates the outside air temperature, and the alternate long and short dash line is the room temperature controlled by the louver device 20. As shown in each of FIGS. 9A to 9C, it can be seen that the room temperature can be brought close to the set temperature by the louver device 20. In addition, by changing the control after sunset depending on the season (summer / winter), it is possible to get closer to the set temperature. The control method may be changed depending on the season.

<Daylighting priority mode>
Next, the lighting priority mode 72 will be described. The daylighting priority mode 72 is a mode in which the position of the feather plate 30 is controlled based on a preset set temperature, and is a mode in which daylighting is emphasized. In this mode as well, the set temperature can be adjusted by the user, and different controls are executed during the daytime when the sun is shining and after sunset. Further, even in the lighting priority mode 72, the control device 50 also controls the exhaust fan 11.

The daytime control of the daylighting priority mode 72 will be described. When the lighting priority mode 72 is set by the mode setting unit 65, the angle control unit 64 monitors the temperature information periodically acquired by the temperature information acquisition unit 61, and if it deviates from the set temperature, it is within the set temperature. The angle θ of the wing plate 30 is controlled so as to enter.

A method of controlling the angle θ in the daytime control of the room temperature priority mode 71 will be described with reference to FIG. FIG. 10 is a schematic diagram of a feather plate 30 for explaining daytime control of the lighting priority mode of the present embodiment. As shown in FIG. 10, the limit angle θ at which only diffusely reflected light (scattered light) enters the room is the angle θ when the plane portion of the wing plate 30 and the incident angle of sunlight are at right angles. At this time, a right triangle (triangle shown in gray in FIG. 10) is established by connecting the ends of the adjacent feather plates 30 and having a hypotenuse of a virtual line segment L parallel to the gradient. The limit angle θ at which only diffusely reflected light enters the room can be expressed by the following equation (5).

θ = 90- (φ + α) ・ ・ ・ Equation (5)

The range of the angle θ in the lighting priority mode 72 can be set as in the equation (6). In the light collection priority mode 72, when the room temperature is higher than the set temperature, the angle of the feather plate 30 with respect to the slope of the roof 3 is rotated at a predetermined angle in a direction that becomes smaller within the angle range shown in the equation (6), and the room temperature is set. When the temperature is lower than the temperature, the control of rotating the blade plate 30 at a predetermined angle in a direction increasing within the angle range shown in the equation (6) is executed. Therefore, in the lighting priority mode 72, only soft diffuse reflected light enters the room. Then, the angle control unit 64 drives the motor 21 of the louver device 20 to control the angle θ of the blade plate 30. For example, the feather plate 30 is rotated by a predetermined angle of 5 degrees in the forward direction (or the reverse direction). At this time, if the angle range is exceeded, the blade 30 is rotated to the limit value of the angle range.

90- (φ + α) ≧ θ> 0 ... Equation (6)

Since the post-sunset control of the lighting priority mode 72 is the same as the post-sunset control of the room temperature priority mode 71 including the angle range, the description thereof will be omitted.

<Sunset mode>
Next, the sun-drenched mode 73 will be described with reference to FIG. The sun-dwelling mode 73 is a mode in which the direct light of the sun is positively taken into the room so that the sun-dwelling can be formed. FIG. 11 is a schematic view of a feather plate 30 for explaining a sunny mode of the present embodiment.

As shown in FIG. 11, in the sunny mode 73, control is performed in which the intake of light is given the highest priority without considering the room temperature. The angle control unit 64 sets the angle θ of the wing plate 30 so that the first mirror surface portion 32 of the wing plate 30 follows the elevation angle of the sun so that the direct light that directly enters the room without being reflected by the wing plate 30 increases. Control. Therefore, the angle θ of the sunny mode 73 can be expressed by the following equation (7).

θ = 180- (φ + α) ・ ・ ・ Equation (7)

In the sunny mode 73, the angle control unit 64 determines the angle θ of the blade plate 30 based on the equation (7). In the sunny mode 73, the wing plate 30 is controlled so as to follow the solar zenith angle, and the wing plate 30 does not take into consideration the temperature information acquired by the first temperature sensor 13 and the second temperature sensor 14. The angle θ will be controlled. In the sunny mode, the angle of the feather plate 30 may be changed based on the temperature information within the range where the direct light enters.

The sunny mode 73 described above is only for daytime control. After sunset, the room temperature priority mode 71 automatically shifts to the post-sunset control, the lighting priority mode 72 post-sunset control, or the cool night mode 74 described later. Further, the sun-drenched mode 73 may be applied only in the designated time zone, and the daytime control of the room temperature priority mode 71 and the daytime control of the daylighting priority mode 72 may be performed in other time zones.

<Cool night mode>
Next, the cool night mode 74 will be described with reference to FIG. FIG. 12 is a schematic view of a feather plate 30 for explaining the cool night mode 74 of the present embodiment. The cool night mode 74 is a mode only for post-sunset control in which the position of the feather plate 30 is determined based on an arbitrary angle θ specified by the user without executing control based on room temperature.

In the cool night mode 74, the angle θ can be determined based on the line of sight 6 of a person. For example, when it is desired to always see the starry sky at night, the angle θ is controlled according to the position of the user (for example, the position of the bed or sofa) or the line of sight 6. The angle θ set through the input unit 81 is stored in the storage device 54 as the angle θ in the cool night mode 74. After that, while the cool night mode 74 is being selected, the feather plate 30 is controlled based on the angle θ until the angle θ is changed. The angle range in the cool night mode 74 is a range from the structural limit angle (for example, about 170 degrees) to 0.

<Manual mode>
Next, the manual mode 75 will be described. The manual mode 75 is a manual mode in which the user directly inputs the angle θ of the blade plate 30 to the control device 50 through the input unit 81. The angle control unit 64 controls the motor 21 of the louver device 20 so that the angle θ is the angle θ input through the input unit 81. The angle range in the manual mode 75 is a range from the structural limit angle (for example, about 170 degrees) to 0.
