Description

  The present invention relates to an electric shutter control device and a building including the same.

  In a building such as a house, a technique of installing an electric shutter device on the outdoor side or indoor side and closing an opening such as a window by the electric shutter device has been put into practical use. In recent years, a technique has been put into practical use that not only opens and closes the window with a shutter curtain, but also performs ventilation and lighting indoors with the shutter curtain half open.

  On the other hand, an air conditioning facility is provided in a building in order to keep the indoor temperature suitably, and the indoor temperature is increased or decreased by cooling and heating the air conditioning facility. Here, in the case where the indoor temperature is raised or lowered by the air conditioning equipment, a technique has been proposed in which cooperative control with the electric shutter device is performed to reduce energy consumption in the building (for example, see Patent Document 1). ). Specifically, when the indoor environment such as the room temperature changes and the energy consumption of the air conditioning equipment changes, the state of the electric shutter device is controlled according to the change in the energy consumption.

However, in the technique disclosed in Patent Document 1, when the energy consumption increases or decreases with changes in the room temperature or the like, the shutter control is performed on the condition that the energy consumption increase or decrease is detected, so that the response of the shutter control is delayed. For example, when the sunlight is strong in summer, the shutter control is not performed unless the room temperature rises and the air conditioning energy increases. As a result, the amount of sunlight introduced into the room cannot be suitably adjusted, and the indoor environment cannot always be properly maintained. Further, as described above, in the configuration in which the shutter control is performed after detecting the increase / decrease in the energy consumption, there is a problem that energy loss is likely to occur.
Japanese Patent No. 3302800

  An object of the present invention is to provide an electric shutter control device capable of optimizing the indoor environment of a building and improving energy efficiency, and a building including the same.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, in order to facilitate understanding, a corresponding configuration example in the embodiment of the invention is appropriately shown in parentheses, etc., but is not limited to the specific configuration shown in parentheses.

  Means 1. The electric shutter control device according to the present invention is provided in a building including an air conditioning facility (air conditioner 17) for air conditioning indoors and an electric shutter device (shutter device 13) for closing an opening (window 12) of the building. Applied. The air conditioning equipment adjusts the indoor temperature to the set temperature. The electric shutter device closes an opening of a building by a shutter curtain (shutter curtain 15). In particular, the environment information acquisition means (shutter controller 30) sequentially acquires outdoor environment information (sunlight information, outside air temperature information, etc.). The solar radiation amount control means (shutter controller 30) drives the shutter curtain based on the acquired outdoor environment information, and controls the amount of sunlight introduced into the room.

  According to the above configuration, since the introduction status of sunlight into the building can be adjusted using direct parameters such as solar radiation information and outside air temperature information as control parameters of the electric shutter device, detection of increase / decrease in the energy consumption of the air conditioning equipment is detected. Unlike the prior art that performs shutter control based on the detection result, the indoor environment can be adjusted with high response and appropriateness. Moreover, the amount of air-conditioning energy can be reduced by suitably performing the solar radiation amount control by the electric shutter device. As a result, the indoor environment of the building can be optimized and energy efficiency can be improved.

  Mean 2. The environmental information acquisition means includes means for calculating the outside air temperature from a detection signal from a sensor or the like. The solar radiation amount control means controls the shutter curtain so that the amount of sunlight introduced to the indoor side is reduced when the outside air temperature is equal to or higher than the cooling reference temperature of the air conditioning equipment. In this case, in the summer, etc., the solar radiation amount control is performed so as to reduce (block) the sunlight inserted into the room on condition that the outside air temperature ≧ the cooling reference temperature. Thereby, solar radiation amount control can be implemented in the condition where the air conditioning facility is cooling or is highly likely to be performed, and accordingly, the energy consumption of the air conditioning facility can be reduced.

  Means 3. The solar radiation amount control means may control the shutter curtain so that the amount of sunlight introduced into the indoor side is reduced when the outside air temperature is higher than the set temperature of the air conditioning equipment or “set temperature + α”. In this case, energy consumption of the air conditioning equipment can be reduced. For example, α is about 1 to 5 ° C.

  Here, the set temperature of the air conditioning equipment may be obtained based on information (remote control operation signal) received from the remote control device for remotely operating the air conditioning equipment.

  Means 4. The electric shutter device has a slat type shutter curtain in which a plurality of slats (slats 21) are connected in the vertical direction as a shutter curtain, and each of the plurality of slats is adjustable in angle. The solar radiation amount control means controls the amount of sunlight introduced into the room by adjusting the angle of the slats. In this case, by adjusting the angle of the slats, it is possible to easily adjust the sunlight inserted into the indoor side while maintaining the indoor brightness.

  Means 5. The electric shutter device is a first inclined state in which the slat is inclined in a direction to reduce the indoor introduction amount of sunlight with reference to a state in which the opening of the building is closed with the slat directed vertically or substantially vertically. And a second tilted state tilted in the direction of increasing the amount of sunlight introduced indoors. The solar radiation amount control means performs the solar radiation amount control with the slats in the first inclined state in the summer and performs the solar radiation control with the slats in the second inclined state in the winter. In this case, in summer, the introduction of sunlight is restricted by adjusting the angle of the slats, and accordingly, energy consumption due to cooling of the air conditioning equipment can be reduced. In winter, the introduction of sunlight is promoted by adjusting the angle of the slats, and accordingly, energy consumption due to heating of the air conditioning equipment can be reduced.

  Means 6. The environmental information acquisition means includes means for calculating an outside air temperature (outdoor temperature) from a detection signal from a sensor or the like. The solar radiation amount control means performs the solar radiation amount control with the slat as the first inclined state when the outside air temperature is equal to or higher than the cooling reference temperature of the air conditioning equipment, while the outside air temperature is equal to or lower than the heating reference temperature of the air conditioning equipment. In some cases, the solar radiation amount control is performed with the slats in the second inclined state. In this case, in the summer season, etc., the solar radiation amount control is performed to reduce (block) the sunlight that enters the room on the condition that the outside air temperature ≧ the cooling reference temperature. In the winter season, the outside air temperature ≦ the heating reference temperature. On the condition that it is, the solar radiation amount control that increases (accepts) the sunlight inserted indoors is performed. As a result, the solar radiation amount control is performed by adjusting the angle of the slats under circumstances where cooling (or heating) is performed or highly likely to be performed by the air conditioning equipment, and accordingly, energy consumption of the air conditioning equipment is reduced. Can do.

  Mean 7 The solar radiation amount control means performs the solar radiation amount control with the slats in the first inclined state when the outdoor air temperature at each time is higher than the set temperature of the air conditioning equipment or “set temperature + α”. When the temperature is lower than the set temperature of the air conditioning equipment or “set temperature−β”, the solar radiation amount control is performed with the slat as the second inclined state. In this case, energy consumption of the air conditioning equipment can be reduced. For example, α and β are about 1 to 5 ° C. (α may be β).

  Here, the set temperature of the air conditioning equipment may be obtained based on information (remote control operation signal) received from the remote control device for remotely operating the air conditioning equipment.

  Means 8. The solar radiation amount control means may be in a state where the slats are directed horizontally when there is no solar radiation. Without solar radiation, indoor temperature does not change due to solar radiation. In this case, by setting the slats in a horizontal state, it is possible to ensure the brightness on the indoor side or to prevent the slats from obstructing the field of view on the outdoor side when viewed from the indoor side.

  Means 9. The environment information acquisition means includes means for calculating the amount of solar radiation from a detection signal from a sensor or the like. The solar radiation amount control means drives the slat so that the slat inclination direction is orthogonal to the solar radiation direction when the solar radiation amount is equal to or greater than a predetermined upper limit in summer, while the solar radiation amount is equal to or lower than a predetermined lower limit in winter. In this case, the slat is driven so that the slat inclination direction is parallel to the solar radiation direction.

  According to the said structure, when the amount of solar radiation becomes more than an upper limit, since the solar radiation shielding effect by a slat becomes the maximum, the cooling efficiency of the air conditioner in summer can be improved. In addition, when the amount of solar radiation is below the lower limit, the solar radiation that is inserted indoors through the slats is maximized, so that the heating efficiency of the air conditioning equipment in the winter can be increased. Thereby, the energy reduction effect in summer and winter can be greatly expected.

  Means 10. The environmental information acquisition means includes means for calculating the solar altitude from a detection signal from a sensor or the like. The solar radiation amount control means adjusts the angle of the slats according to the solar altitude. Throughout the year, the solar altitude changes at the same time, and becomes smaller as the distance from the summer solstice is reached, with the summer solstice at its maximum. In this case, the introduction of sunlight into the room can be properly managed by adjusting the angle of the slats according to the solar altitude.

  Since the solar altitude is determined according to the season and the time zone within a day, the solar altitude can be defined in advance for each date and time as calendar information. In this case, instead of means for calculating the solar altitude from the detection signal of a sensor or the like, it is possible to employ means for estimating the solar altitude according to the season or time zone.

  Means 11. The solar radiation amount control means may adjust the angle of the slats based on the operating status (set temperature, operating time, etc.) of the air conditioning equipment. In this case, the solar radiation amount control by the electric shutter device can be performed in accordance with the load condition of the air conditioning equipment, and the burden on the air conditioning equipment can be reduced.

  Means 12. The shutter curtain includes means for setting an angle adjustment area for adjusting the angle of the slat and a non-angle adjustment area for not adjusting the angle, and the solar radiation amount control means adjusts the slat angle for the slat in the angle adjustment area. It is good to carry out. In this case, an electric shutter control device that also considers crime prevention can be realized by adjusting the slat angle only to a part of the shutter curtain. When security is considered as in this configuration, it is desirable to install the electric shutter device on the outdoor side of the building.

As a configuration for adjusting the slat angle by limiting a part of the area of the shutter curtain, it may be embodied as follows.
At least a normal mode (at-home mode) and a security mode are set as the shutter control mode. In the normal mode, the entire area of the shutter curtain is set as the angle adjustment area, and in the security mode, a part of the shutter curtain is set as the angle. An adjustment area is preferable (Means 13).
As the shutter control mode, normal mode (at-home mode), security mode, and outing mode are set. In the normal mode, the entire area of the shutter curtain is set as the angle adjustment area, and in the security mode, a part of the shutter curtain is set. The angle adjustment area is used, and in the outing mode, the entire area of the shutter curtain may be the non-angle adjustment area (means 14).

  Means 15. The solar radiation amount control means may change the solar radiation amount control mode based on the direction in which the electric shutter device is provided. That is, in a building, the amount of solar radiation and the daylight hours differ depending on the direction. In this case, it is possible to realize further optimization of the indoor environment and further improvement of energy efficiency by changing the solar radiation amount control mode according to which direction the electric shutter device is located.

  For example, in a building in which at least two window portions are provided in any of the east, west, north, and south of the living room and an electric shutter device is installed in each of the windows, the control mode of each shutter device may be different.

[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In the present embodiment, an electric shutter device is installed on the outdoor side of the window in a building such as a house, and in particular, by adding a blind function to the shutter device, the amount of solar radiation to the indoor side can be adjusted as appropriate. ing. FIG. 1 is a diagram illustrating a schematic configuration of a room in a building provided with a shutter device.

  In FIG. 1, a window 12 is provided in a building room 11, and a shutter device 13 is provided on the outdoor side of the window 12. The shutter device 13 includes a horizontally-long box-like shutter case 14 attached above the window portion 12 and a slat-type shutter curtain 15 that can be stored while being wound in the shutter case 14. ing. The window portion 12 is closed when the shutter curtain 15 is pulled out (lowered) from the shutter case 14, and the window portion 12 is opened when the shutter curtain 15 is wound up (raised) by the shutter case 14. ing. In the present embodiment, such an opening / closing operation of the shutter curtain 15 is realized by an electric drive mechanism, and details thereof will be described later.

  An air conditioner 17 for performing indoor air conditioning is attached in the living room 11. The air conditioner 17 can be remotely operated by a remote control device 18, and the room temperature is controlled based on the room temperature (target set temperature) set by the remote control device 18. In this case, the air conditioner 17 includes a temperature sensor 17a that detects an actual room temperature and an air conditioner controller (air conditioner controller) 17b that executes various controls for air conditioning. Temperature feedback control or the like is appropriately executed so as to match the set temperature.

  Next, the configuration of the shutter device 13 and the control system using the shutter device 13 will be described with reference to FIG. 2, illustration of the shutter case 14 provided in the upper part of the shutter apparatus 13 and the guide rail provided in the right and left both ends of the shutter apparatus 13 is abbreviate | omitted for convenience of explanation.

  In the shutter device 13, the shutter curtain 15 is configured by connecting a number of slats 21 up and down. The multiple slats 21 are configured such that a part of the slats adjacent to each other in the vertical direction are engaged with each other, and the multiple slats 21 are integrally raised or lowered by mutual engagement between the slats 21. Thereby, the opening / closing operation | movement as the shutter curtain 15 is realizable. In addition, since the structure of the engagement connection between each slat is known, the description by illustration is abbreviate | omitted here.

  A winding drum 22 is connected to the uppermost slat among a large number of slats 21, and the winding drum 22 is rotated in either the forward or reverse direction by a winding drive unit 23 formed of an electric motor or the like. The shutter curtain 15 (slat 21) is wound or pulled out. Thereby, the shutter curtain 15 is raised or lowered. As a configuration for winding the slat, in addition to the configuration having the winding drum 22 as described above, a configuration in which a plurality of disk bodies are used and the shutter curtain 15 (slat 21) is wound around the disk body can be applied. .

  An opening / closing guide mechanism 25 for adjusting the angle (slat angle) of each slat 21 is provided on the side of the shutter curtain 15. The opening / closing guide mechanism 25 has an engagement link portion 26 that can be engaged with a part of each slat 21, and the slat angle can be adjusted by the engagement link portion 26. Here, when the slat angle adjustment is not performed, that is, when each slat 21 is standing in the vertical direction, the engagement link portion 26 is not engaged with each slat 21 and when the slat angle adjustment is performed, The engaging link portion 26 is configured to engage each slat 21 to change the individual inclination angle. In this case, the open / close guide mechanism 25 is driven by a slat drive unit 27 made of an electric motor or the like, so that the slats 21 are simultaneously adjusted to an arbitrary angle.

  The winding drive unit 23 and the slat drive unit 27 are each driven by a drive signal output from the shutter controller 30. However, the electrical configuration will be described later.

  Each slat 21 can be adjusted in angle within an adjustment range of -90 degrees to 90 degrees, with the slat 21 standing in the vertical direction as a reference (0 degree), and the angle adjusted state is illustrated in FIG. 3 will be described. In FIG. 3, the left side of each slat 21 is the outdoor side, and the right side is the indoor side. Further, the angle at which each slat 21 is tilted from the vertical standing state is defined as the slat angle θ, and the slat angle θ when the slat 21 is rotated in the clockwise direction in the drawing is defined as a positive angle. The slat angle θ when rotated clockwise is a negative angle.

  In FIG. 3, (a) shows an initial state in which the angle is not adjusted, and the slat angle θ = 0 degrees. (B) shows the state in which each slat 21 is inclined 45 degrees on the positive side, (c) shows the state in which each slat 21 is inclined 45 degrees on the negative side, and (d) shows that each slat 21 is inclined 90 degrees on the positive side. The tilted state (the same applies when tilted 90 degrees on the negative side) is shown.

  Note that (b) in FIG. 3 corresponds to a “first inclined state” (a state in which the amount of sunlight introduced indoors is decreased), and (c) is a “second inclined state” ( This is equivalent to a state in which the amount of sunlight introduced indoors is inclined in the direction of increasing.

  FIG. 4 is a block diagram showing an outline of a control system related to the shutter device 13.

  In FIG. 4, the shutter controller 30 is mainly composed of a well-known microcomputer having a CPU 31, various memories 32 such as ROM and RAM, and the shutter controller 30 includes an outside air temperature sensor 41 for detecting outside air temperature. A solar radiation amount sensor 42 for detecting the solar radiation amount and a solar altitude sensor 43 for detecting the solar altitude (sunlight angle) are respectively connected. Detection signals from these sensors are input to the shutter controller 30, whereby outdoor solar radiation environment information (outside temperature, solar radiation amount, solar altitude) can be sequentially acquired. The sensors 41 to 43 are preferably provided in the shutter case 14, for example.

  The shutter controller 30 is connected to a setting device 44 for setting the shutter control state. The setting device 44 is attached to, for example, the inner wall of the living room 11, and includes an input member such as a button to be input by a user and a display unit (not shown) including a liquid crystal display. Specifically, the setting device 44 is provided with a shutter opening / closing button for opening and closing the shutter curtain 15, a slat angle adjusting button for adjusting a slat angle, and the like. Thus, the opening / closing adjustment of the shutter curtain 15 and the slat angle adjustment are performed according to the user's request. The shutter controller 30 and the setting device 44 may be configured as an integrated device.

  In addition, the shutter controller 30 has a wireless communication function for performing wireless communication with the air-conditioning remote control device 18, and can receive room temperature information such as a room set temperature from the remote control device 18. Yes.

  The shutter controller 30 performs opening / closing control of the shutter curtain 15 and angle adjustment control of each slat 21 based on the detection signals of the sensors 41 to 43, the setting operation signal of the setting device 44, the room temperature information, and the like. To do. At this time, a drive signal is output from the shutter controller 30 to the winding drive unit 23 and the slat drive unit 27, and the shutter opening / closing amount and the slat angle are adjusted accordingly. As the angle adjustment control of the slat 21, speed control by PAM (Pulse Amplitude Modulation) control is used.

  Next, details of slat angle control, which is a main part of the present embodiment, will be described. In this embodiment, in order to keep the environment in the living room 11 comfortable, the slat angle of the shutter device 13 is automatically adjusted based on the outdoor environment information and the indoor environment information, and is inserted into the living room 11 by this slat angle adjustment. The amount of solar radiation is adjusted. Considering the climate throughout the year, it is desirable to change the slat angle adjustment mode, for example, in summer and winter. In summer, the amount of solar radiation inserted into the room 11 is limited, whereas in winter the room is 11 is actively incorporating solar radiation.

  Specifically, in the summer and the seasons before and after it, the solar radiation is relatively strong and the outside temperature is also relatively high. Therefore, the slat angle is automatically adjusted so that sunlight (sunlight) is blocked by the shutter curtain 15. Thereby, the excessive solar heat inserted in the living room 11 is suppressed, and cooling energy reduction and the comfort improvement of a living room are achieved. In this case, basically, the slat angle adjustment is performed with the slat angle θ as a positive angle as shown in FIG. On the other hand, in winter, solar radiation is relatively weak and the outside temperature is relatively low. Therefore, the slat angle is automatically adjusted so that a large amount of sunlight (sunlight) is taken into the living room 11 through the shutter curtain 15. Thereby, solar heat is positively introduced into the living room 11, and heating energy is reduced and comfort in the living room is improved. In this case, basically, the slat angle adjustment is performed with the slat angle θ as a negative angle as shown in FIG.

  Next, the slat angle control process in the shutter device 13 will be described. In the present embodiment, the slat angle control process executed in the summer and intermediate periods (April to October) and the slat angle control process executed in the winter (November to March) are individually set. These processes can be used properly according to the season. FIG. 5 is a flowchart showing the slat angle control process in the summer and intermediate periods, and FIG. 6 is a flowchart showing the slat angle control process in the winter. Each process is executed by the shutter controller 30. 5 and 6 is executed under the condition that the shutter curtain 15 is in a state where it is completely lowered (lowered state).

  In FIG. 5, first, in step S101, various types of information relating to the outdoor environment and the indoor environment are read. Specifically, the outside air temperature information detected by the outside air temperature sensor 41, the solar radiation amount information detected by the solar radiation amount sensor 42, the solar altitude information detected by the solar altitude sensor 43, and the indoor set temperature information acquired from the air conditioning remote control device 18. Is read.

  Next, in step S102, it is determined whether or not the outside air temperature at that time is equal to or higher than a predetermined cooling reference temperature (for example, 24 ° C.). The cooling reference temperature is a temperature defined in advance as a room temperature that requires cooling, but may be changed as appropriate according to the capability of the air conditioner 17 or the user's desire. If the outside air temperature <24 ° C., it is determined in step S103 whether or not the outside air temperature is equal to or higher than “the indoor set temperature of the air conditioner 17 + 1 ° C.”. That is, it is determined whether or not the temperature difference between the outside air temperature and the indoor set temperature (= outside air temperature−indoor set temperature) is a predetermined value (for example, 1 ° C.) or more.

  If the outside air temperature <24 ° C. and the outside air temperature <the indoor set temperature + 1 ° C., the process proceeds to step S104, a delay process for waiting for a predetermined time is performed, and then the process returns to step S101. If the outside air temperature ≧ 24 ° C. or the outside air temperature ≧ the indoor set temperature + 1 ° C., the process proceeds to step S105.

  In step S105, it is determined whether there is solar radiation. If there is no solar radiation, the process proceeds to step S106, and the slat angle is set to 90 degrees (horizontal setting). This is the state shown in FIG. Then, after delay processing is performed in step S104, the process returns to step S101.

  If there is solar radiation, the process proceeds to step S107, and it is determined whether or not the solar radiation amount at that time is equal to or greater than a predetermined upper limit set amount. This upper limit set amount is an upper limit guard value for determining that the amount of solar radiation is excessive.

  If the solar radiation amount <the upper limit set amount, the process proceeds to step S108, and the slat angle is arbitrarily adjusted. At this time, the slat angle is adjusted according to the solar altitude (sunlight angle). Specifically, as shown in FIG. 7, the slat angle θ is adjusted in accordance with the solar altitude (sunlight angle X). 7A shows a case where the solar altitude (sunlight angle X) is relatively large, and FIG. 7B shows a case where the solar altitude (sunlight angle X) is relatively small. Comparing (a) and (b), the larger the solar altitude (sunlight angle X), the larger the slat angle θ is adjusted. After the process in step S108, the delay process is performed in step S104, and the process returns to step S101.

  Since the solar altitude (sunlight angle) varies depending on the time of day, the slat angle (or slat angle adjustment range) is determined in advance according to the time of day, and the slat angle adjustment is performed for each time of day. May be. As an example, the time zone for adjusting the slat angle in one day is as follows: morning time zone (6 o'clock to 10 o'clock), day time zone (10 o'clock to 15 o'clock), evening time zone (15 o'clock to 20 o'clock) And adjust the slat angle in each time zone. The outline of the control is shown in FIG. 8 (here, the case where the shutter device 13 is provided on the south surface of the building is shown). In this case, the slat angle θ is adjusted in the range of 45 ° to 90 ° during the morning time zone, the slat angle θ is adjusted in the range of 45 ° to 60 ° during the daytime zone, and in the evening time zone. The slat angle θ is adjusted in the range of 45 degrees to 90 degrees. At this time, the slat angle θ may be gradually changed with time in each angle adjustment range in each time zone.

  Returning to the description of FIG. 5, when the amount of solar radiation is equal to or greater than the upper limit set amount (that is, when the amount of solar radiation is excessive), the process proceeds to step S109 to determine whether the solar radiation direction at that time is orthogonal to the slat inclination direction. judge. That is, it is determined whether or not the solar altitude (sunlight angle) and the slat angle match. If the solar radiation direction and the slat inclination direction are orthogonal to each other, the process directly proceeds to step S104, performs a predetermined delay process, and then returns to step S101.

  If the solar radiation direction and the slat inclination direction are not orthogonal, the process proceeds to step S110. In step S110, the slat angle is adjusted so that the solar radiation direction and the slat inclination direction are orthogonal to each other (slat angle orthogonal adjustment is performed). Then, after delay processing is performed in step S104, the process returns to step S101.

  FIG. 6 is a flowchart showing a slat angle control process in winter, and this process is executed by the shutter controller 30.

  In FIG. 6, first, in step S201, various information (outside air temperature information, solar radiation amount information, solar altitude information, indoor set temperature information) relating to the outdoor environment and the indoor environment is read. Next, in step S202, it is determined whether or not the outside air temperature at that time is equal to or lower than a predetermined heating reference temperature (for example, 10 ° C.). The heating reference temperature is a temperature defined in advance as a room temperature that requires heating, but may be appropriately changed according to the capability of the air conditioner 17 or the user's desire. When the outside air temperature> 10 ° C., it is determined in step S203 whether or not the outside air temperature is equal to or lower than “the indoor set temperature of the air conditioner 17—1 ° C.”. That is, it is determined whether or not the temperature difference between the indoor set temperature and the outside air temperature (= indoor set temperature−outside air temperature) is a predetermined value (for example, 1 ° C.) or more.

  If the outside air temperature> 10 ° C. and the outside air temperature> the indoor set temperature−1 ° C., the process proceeds to step S204, and after performing a delay process for waiting for a predetermined time, the process returns to step S201. If the outside air temperature ≦ 10 ° C. or the outside air temperature ≦ the indoor set temperature−1 ° C., the process proceeds to step S205.

  In step S205, it is determined whether there is solar radiation. If there is no solar radiation, the process proceeds to step S206, and the slat angle is set to 90 degrees (horizontal setting). This is the state shown in FIG. Then, after delay processing is performed in step S204, the process returns to step S201.

  If there is solar radiation, the process proceeds to step S207 to determine whether the solar radiation amount at that time is equal to or less than a predetermined lower limit set amount. This lower limit set amount is a lower limit guard value for determining that the amount of solar radiation is very small.

  When the amount of solar radiation> the lower limit set amount, the process proceeds to step S208, and the slat angle is arbitrarily adjusted. At this time, as described above, the slat angle is adjusted in accordance with the solar altitude (sunlight angle). After the process in step S208, the delay process is performed in step S204, and then the process returns to step S201.

  Here, also in winter, as in the summer, the solar altitude (sunlight angle) varies depending on the time zone of the day, so the slat angle (or slat angle adjustment range) is determined in advance corresponding to the time zone, You may make it perform slat angle adjustment for every time slot | zone. As an example, the time zone for adjusting the slat angle in one day is as follows: morning time zone (6 o'clock to 10 o'clock), day time zone (10 o'clock to 15 o'clock), evening time zone (15 o'clock to 20 o'clock) And adjust the slat angle in each time zone. An outline of the control is shown in FIG. 9 (in this case, the shutter device 13 is provided on the south surface of the building). In this case, the slat angle θ is adjusted in the range of −75 degrees to −60 degrees in the morning time zone, the slat angle θ is adjusted to −60 degrees in the day time zone, and the slat angle is adjusted in the evening time zone. The angle θ is adjusted in the range of −75 degrees to −60 degrees. Here, in any case, the slat angle θ is a negative angle, that is, an angle synchronized with the solar radiation direction. At this time, the slat angle θ may be gradually changed with time in each angle adjustment range in each time zone.

  If the amount of solar radiation ≦ the lower limit set amount (that is, the amount of solar radiation is very small), the process proceeds to step S209 to determine whether the solar radiation direction at that time is parallel to the slat inclination direction. If the solar radiation direction and the slat inclination direction are parallel, the process proceeds to step S204 as it is, and after performing a predetermined delay process, the process returns to step S201.

  If the solar radiation direction and the slat inclination direction are not parallel, the process proceeds to step S210. In step S210, the slat angle is adjusted so that the solar radiation direction and the slat inclination direction are parallel (slat angle parallel adjustment is performed). Then, after delay processing is performed in step S204, the process returns to step S201.

  According to this embodiment described in detail above, since the direct introduction parameters such as solar radiation information and outside air temperature information can be adjusted as control parameters of the shutter device 13, the introduction status of sunlight into the living room 11 can be adjusted. Unlike the prior art in which increase / decrease detection is performed on energy consumption and shutter control is performed based on the detection result, the indoor environment can be adjusted with high response and appropriateness. The solar radiation amount control by adjusting the slat angle can be suitably performed, so that the air conditioning energy can be reduced. As a result, the indoor environment of the building can be optimized and energy efficiency can be improved.

  In the above configuration, the air conditioning control of the air conditioner 17 and the shutter control of the shutter device 13 are independent control systems. Therefore, unlike the technology that integrates air-conditioning control and shutter control, it is possible to avoid complication of the system and the associated high cost. The shutter controller 30 only acquires set temperature information from the remote control device 18 as information on the air conditioner side. Even if only the air conditioner 17 is replaced, shutter control can be realized continuously without requiring a large specification change.

  In summer, etc., the amount of solar radiation is controlled to block the introduction of sunlight on the condition that the outside air temperature ≥ cooling reference temperature or the outside air temperature ≥ indoor set temperature + 1 ° C. The amount of solar radiation was controlled so as to allow the introduction of sunlight on the condition that the reference temperature or the outside air temperature ≤ indoor set temperature -1 ° C. Thereby, the amount of solar radiation is controlled by adjusting the slat angle under a situation where the air conditioning device 17 is cooling (or heating) or is highly likely to be performed, and accordingly, the energy consumption of the air conditioning device 17 is reduced. be able to. In this case, whether air conditioning control (cooling or heating) is performed in accordance with the solar radiation amount control is arbitrary, and in any case, it can contribute to the optimization of the indoor environment.

  Since the slat 21 is oriented horizontally when there is no solar radiation, the brightness in the living room 11 is ensured, or the slat 21 is not obstructed from the field of view on the outdoor side when viewed from inside the living room 11. Can do.

  In the summer, when the amount of solar radiation exceeds a predetermined upper limit, the slat 21 is driven so that the slat inclination direction is orthogonal to the solar radiation direction, so that the solar radiation shielding effect by the slat 21 is maximized and the cooling efficiency of the air conditioner 17 is improved. Can be increased. In addition, when the amount of solar radiation is below a predetermined lower limit in winter, driving the slats 21 so that the slat inclination direction is parallel to the solar radiation direction, the solar radiation inserted into the living room 11 through the slats 21 is maximized, and the air conditioner The heating efficiency of 17 can be increased. Thereby, the energy reduction effect in summer and winter can be greatly expected.

  Since the slat angle adjustment is performed according to the solar altitude, the introduction of sunlight into the living room 11 can be properly managed.

[Second Embodiment]
Next, the second embodiment will be described with a focus on differences from the first embodiment.

  FIG. 10 is a plan view of the living room 50. As shown in the figure, windows 51, 52, and 53 are provided on the east, west, and south faces of the living room 50, respectively, and each of these windows 51 to 53 is provided. Are provided with shutter devices 55, 56 and 57, respectively. In the present embodiment, an application example in the case where shutter devices are provided in different directions will be described. The shutter devices 55 to 57 have the same configuration as that of the shutter device 13 described above, and are individually controlled by a common shutter controller 60.

  In such a case, in the living room 50, the amount of solar radiation (intensity of sunlight) and the sunshine time zone inserted from the windows 51 to 53 differ depending on the direction. Therefore, the amount of solar radiation is individually controlled for each of the shutter devices 55 to 57 on the east, west, and south surfaces.

  11 and 12 are diagrams showing an outline of the slat angle adjustment pattern in the shutter devices 55 to 57 of each direction, and FIG. 11 shows the slat angle adjustment pattern in the summer and the intermediate period (April to October). FIG. 12 shows a slat angle adjustment pattern in winter (November to March). Moreover, FIG. 13 is a figure which shows the change of the global solar radiation amount with respect to the time of the day in every summer (east surface, west surface, south surface) in summer and winter. 11 and 12, a slat angle adjustment pattern is defined for each direction (east surface, west surface, south surface) in accordance with the solar radiation time zone shown in FIG. In this case, the amount of solar radiation is controlled according to the solar altitude while tracking the solar radiation.

  In FIG. 11 (summer and intermediate slat angle adjustment patterns), in the morning time zone, the slat angle adjustment is performed in the illustrated angle range mainly for the east and south shutter devices. For the western shutter device, since there is no solar radiation at first, the slat angle θ is maintained at 90 degrees (horizontal state), and then the angle is gradually adjusted. In the daytime period, the slat angle adjustment is performed in the illustrated angle range for each of the east, west and south shutter devices. Further, in the evening time zone, the slat angle adjustment is performed in the illustrated angle range mainly for the west and south shutter devices. The east surface shutter device is maintained at a slat angle θ of 90 degrees (horizontal state) as the solar radiation disappears.

  In FIG. 12 (slat angle adjustment pattern in winter), in the morning time zone, the slat angle adjustment is performed in the illustrated angle range mainly for the east and south shutter devices. For the western shutter device, the slat angle θ is held at −90 degrees (horizontal state). During the daytime, the east and west shutter devices are held at θ = −90 degrees (horizontal state), and the south shutter device is held at θ = −60 degrees. Further, in the evening time zone, the slat angle adjustment is performed in the illustrated angle range mainly for the west and south shutter devices. The shutter device on the east surface is held at θ = −90 degrees (horizontal state).

  As described above, according to the second embodiment, since the solar radiation amount control mode is changed based on the direction in which the shutter devices 55 to 57 are provided, further optimization of the indoor environment and further improvement of energy efficiency are achieved. Can be realized.

[Third Embodiment]
In the third embodiment, three modes of a home mode, a crime prevention mode, and an outing mode are defined as control modes of the shutter device 13, and the shutter control mode corresponding to the set mode is changed each time. . In the present embodiment, the configuration of FIG. 4 is applied mutatis mutandis.

  Basically, each mode is set as follows. The home mode is set when the user is at home, the crime prevention mode is set when the number of people in the building is small or when the user goes to bed, and the outing mode is set when the user is out. Each of the above modes is appropriately set according to the input operation of the setting device 44 by the user. However, the presence / absence of the user can be detected by a human sensor installed in the building, and the above modes can be automatically set according to the detection result. When a user wears a human body sensor, the user's sleep state can be detected by the human body sensor, and the crime prevention mode can be automatically set according to the detection result.

  In the present embodiment, the slat angle adjustment area in the shutter curtain 15 is changed according to each of the above modes when the shutter curtain 15 is lowered. The outline is shown in FIG. In FIG. 14, the slat angle adjustment area is indicated by a hatched frame.

  In the home mode shown in FIG. 14A, the slat angle can be adjusted over the entire area of the shutter curtain 15 in the vertical direction (area A1 in the figure). In the crime prevention mode shown in FIG. 14B, the slat angle can be adjusted only in the upper predetermined range of the shutter curtain 15 (area A2 in the figure). The area A2 is an area including only a few (for example, five) slats from the top with the shutter curtain 15 completely lowered. In addition, in the outing mode shown in FIG. 14C, the slat angle adjustment is impossible in the entire area of the shutter curtain 15. In FIG. 14, areas A1 and A2 correspond to “angle adjustment areas”, and other areas correspond to “non-angle adjustment areas”.

  FIG. 15 is a flowchart showing the slat angle control process in the present embodiment. This process is executed by the shutter controller 30 instead of the processes in FIGS. 5 and 6 described above.

  In FIG. 15, a mode determination process is performed in step S301. This mode determination process is a process for determining which mode is currently at home / crime prevention / outing. Next, in step S302, a slat angle adjustment area is set based on the determination result of step S301. At this time, as shown in FIG. 14, a slat angle adjustment area is set for each mode.

  Thereafter, in step S303, the process branches according to the mode determination result in step S301. When the home mode determination is made, the process proceeds to step S304, and the slat angle adjustment process in the home mode is executed. The slat angle adjustment processing in the home mode is based on the processing contents of FIG. 5 and FIG. 6 described above, and the slat angle is based on outdoor environment information such as solar radiation information and outside air temperature information, and other seasons and time zones. Control is implemented.

  When the security mode is determined, the process proceeds to step S305, and the slat angle adjustment process in the security mode is executed. The slat angle adjustment processing in the crime prevention mode is similar to the processing contents of FIG. 5 and FIG. 6 described above except that the slat angle adjustment area is limited, and outdoor environment information such as solar radiation information and outside air temperature information, The slat angle control is performed based on other seasons and time zones. When the outing mode determination is made, the present process is terminated without performing the slat angle adjustment.

  As described above, according to the third embodiment, since the slat angle adjustment is performed for the slats in the slat angle adjustment area corresponding to each mode, it is possible to realize the shutter control in consideration of crime prevention.

  Note that the configuration may be such that the slat angle adjustment is permitted only in the home mode. In addition, the shutter control mode can be set in a mode other than the above, and for example, one of two modes of the home mode and the security mode may be selectively set.

[Other Embodiments]

Based on the operation status of the air conditioner 17, it is good also as a structure which adjusts a slat angle like the following (1) and (2).
(1) The set temperature of the air conditioner 17 is used as a control parameter for solar radiation control. In this case, in the summer, the slat angle adjustment is performed so that the degree of sunlight shielding by the slats 21 increases as the cooling set temperature decreases. In winter, the slat angle adjustment is performed so that the degree of sunlight passing through the slats 21 increases as the heating set temperature increases.
(2) The operating time of the air conditioner 17 is set as a control parameter for the solar radiation amount control. In this case, in the summer, when the operating time of the air conditioner 17 exceeds a predetermined time, the slat angle adjustment is performed so that the degree of sunlight shielding by the slat 21 is increased. In winter, when the operating time of the air conditioner 17 exceeds a predetermined time, the slat angle adjustment is performed so that the degree of sunlight passing through the slat 21 is increased.

  According to each form of said (1) and (2), the solar radiation amount control by the shutter apparatus 13 can be performed according to the load condition of the air conditioner 17, and the burden of the air conditioner 17 can be reduced. .

  In the above embodiment, the amount of solar radiation into the living room 11 is adjusted by adjusting the slat angle in the shutter device 13, but this configuration is changed. For example, in the shutter device 13, a configuration in which the gap dimension between the slats can be adjusted is added, and the amount of solar radiation into the living room 11 is adjusted by variably adjusting the gap dimension within a predetermined range (for example, 0 to several tens of mm). Increase / decrease adjustment. Even in this configuration, similarly to the above, the solar radiation amount control is performed so as to block the introduction of sunlight on the condition that the outside air temperature ≧ the cooling reference temperature or the outside air ≧ the indoor set temperature + α ° C. In winter, etc., the solar radiation amount control may be performed so as to allow the introduction of sunlight under the condition that the outside air temperature ≦ the heating reference temperature or the outside air temperature ≦ the indoor set temperature−β ° C.

  It is also possible to apply a configuration having a shutter curtain other than the slat type shutter curtain as the electric shutter device. In short, the present invention can be widely applied to an electric shutter device that can variably adjust the amount of solar radiation passing through the shutter curtain.

  In each of the above embodiments, the application example of the electric shutter device installed on the outdoor side of the building has been described. However, the present invention can be similarly applied to the electric shutter device installed on the indoor side of the building. However, from the viewpoint of building crime prevention, it can be said that a configuration in which the electric shutter device is installed on the outdoor side is desirable.
