Description

本発明は、日射遮蔽制御装置に関するものである。   The present invention relates to a solar radiation shielding control device.

近年、温暖化による省エネルギの社会的要求が増えてきている。特に、昼光（日光）の導入を利用した省エネルギ制御は、自然エネルギ利用として期待は高く、また昼光を建物開口部である窓から執務室内（空調対象エリア）へ導入する場合、窓本来の機能である利用者の外部環境とのつながりを促すことから執務者の開放感や快適性の面からも有効と考えられる。このような背景により、近年の制御技術の発展に伴い、外環境の状態に合わした日射遮蔽をブラインドの開閉により自動的に行う日射遮蔽制御装置が普及しつつある。このような日射遮蔽制御装置は、日中の照明エネルギ削減を目的としており、就業以前に関しては制御の対象外であった。しかし夏季において就業以前にブラインドを開放すれば、室内に日射負荷が直接入射する恐れもあり、冷房負荷の増加が懸念される。また冬季において昼光が補助暖房として利用できるにも拘わらず、セキュリティ上始業時刻までブラインドを閉じたままとするため有効に利用されていない場合もある。 In recent years, social demands for energy saving due to global warming have increased. In particular, energy-saving control using daylight (sunlight) is expected to be a natural energy utilization, and when daylight is introduced from a window that is a building opening into a office room (area subject to air conditioning), It is considered to be effective from the viewpoint of the openness and comfort of the office worker because it promotes the connection with the external environment of the user, which is a function of. Against this background, with the recent development of control technology, solar shading control devices that automatically perform solar shading according to the state of the external environment by opening and closing the blinds are becoming widespread. Such a solar shading control device is intended to reduce daytime lighting energy, and was not subject to control before work. However, if the blinds are opened before the start of work in the summer, there is a concern that the solar radiation load may directly enter the room, which may increase the cooling load. Also despite daylight it can be used as auxiliary heating in winter, sometimes not effectively used to remain closed blind to security opening time.

一方季節や時刻別にきめ細かくブラインドを制御する方法が提供されている（例えば、特許文献１）。

ここでブラインドＩｃｏｎｔ１０は図２に示すように、現在時刻をシステムタイマ（図示せず）から取得して出力する時計部１００と、制御対象となる空調対象エリアＡでの事業所の始業時刻を記憶する情報記憶部１０１と、計測Ｉｃｏｎｔ４０から日射量計４１、照度計４２の計測情報を取得する日射状態取得部１０２と、空調Ｉｃｏｎｔ３０から空調の動作モード（冷暖房状態）の情報を取得する動作モード取得部１０３と、空調対象エリアＡに設けた人検知センサ１０５からの人の存否の検知情報を取得する在席者情報取得部１０４と、時計部１００，情報記憶部１０１，各取得部１０２〜１０４の情報を取り込んで、当該空調対象エリアＡの環境情報を把握する情報処理部１０６と、該情報処理部１０６で把握した情報に基づいて後述するようにブラインド１を制御する制御信号を生成する制御部１０７とで構成される。   Here, as shown in FIG. 2, the blind icon 10 stores the clock unit 100 that obtains and outputs the current time from a system timer (not shown), and stores the start time of the office in the air conditioning target area A to be controlled.

The illuminance may be converted from the amount of solar radiation measured by the solar radiation meter 41 to illuminance.

次に本実施形態の動作を説明する。   Next, the operation of this embodiment will be described.

まず、図３に示すようにビルオートメーションシステムをスタート（ステップＳ１）させると、日射制御システムのブラインドＩｃｏｎｔ１０の制御部１０７は、時計部１００からの現在時刻と、日射状態取得部１０２が取得する日射量計４１からの日射量情報とを情報処理部１０６を通じて取り込み、当該システムの設置場所に対応した現在時刻（日時）での太陽位置を求めるとともに、この太陽位置と予め設定した日の出判定の閾値を日射量が超えるか否から日の出の判定を行い、且つ現在時刻が始業時刻前であるか否かの判定を行う（ステップＳ２）。   First, as shown in FIG. 3, when the building automation system is started (step S <b> 1), the control unit 107 of the blind Icont 10 of the solar radiation control system performs the current time from the clock unit 100 and the solar radiation acquired by the solar radiation state acquisition unit 102. The solar radiation amount information from the meter 41 is taken in through the information processing unit 106, and the sun position at the current time (date and time) corresponding to the installation location of the system is obtained, and this sun position and a preset sunrise determination threshold value are obtained. Whether or not the amount of solar radiation exceeds is determined to determine sunrise, and whether or not the current time is before the start time is determined (step S2).

ここで日射量に基づいて日の出と判定し且つ現在時刻が始業時刻前である場合には制御部１０７は空調Ｉｃｏｎｔ３０から空調装置３ｂの動作モードを動作モード取得部１０３，情報処理部１０６を通じて取り込み、現在の空調装置３ｂの動作モードが”冷房”か”暖房”かを判定する（ステップＳ３）。そして”冷房”と判定した場合には制御部１０７は、ブラインド１のスラット１ａを全閉させる始動前モード用の制御信号を生成し、ブラインド１の駆動装置（図示せず）を制御する。これによりブラインド１は遮蔽状態（ステップＳ４）となって、始業前に空調対象エリアＡ内の温度が日射Ｘにより上昇するのを抑制する。この始動前モードにおけるブラインド制御のステップＳ２〜Ｓ４の処理は現在時刻が始業時刻になるまで繰り返されることになり、ステップＳ２において、現在時刻が就業時間（始業時刻）と判定されると、予めプログラミングされている就業時間帯のブラインド１の制御を行う通常モードへ移行することになる（ステップＳ５）。図４（ａ）は上述の”冷房”の動作モードにおけるブラインド１の開き角度の変化を示すタイミングチャートであり、日の出（ｔ１）から始業時刻（ｔ２）までは全閉状態（図４（ｂ）の（イ）参照）となるようにブラインド１のスラット１ａの開き角度（開閉度）が制御され、始業時刻（ｔ２）からは日照量や照度に基づいた通常制御により開き角度が制御され（図４（ｂ）の（ロ）参照）、例えば日射Ｘが無くなる日の入り時（ｔ３）には全閉される。   Here, when the sunrise is determined based on the amount of solar radiation and the current time is before the start time, the control unit 107 takes in the operation mode of the air conditioner 3b from the air conditioning icon 30 through the operation mode acquisition unit 103 and the information processing unit 106, It is determined whether the current operation mode of the air conditioner 3b is “cooling” or “heating” (step S3). When it is determined as “cooling”, the control unit 107 generates a control signal for the pre-start mode for fully closing the slats 1a of the blind 1, and controls the drive device (not shown) of the blind 1. Thereby, the blind 1 becomes a shielding state (step S4), and suppresses that the temperature in the air-conditioning target area A rises due to the solar radiation X before the start of work. The processing in steps S2 to S4 of the blind control in the pre-start mode is repeated until the current time becomes the start time. When it is determined in step S2 that the current time is the work time (start time), programming is performed in advance. The operation shifts to the normal mode in which the blind 1 in the working hours is controlled (step S5). FIG. 4A is a timing chart showing a change in the opening angle of the blind 1 in the above-described “cooling” operation mode, and is fully closed from sunrise (t1) to start time (t2) (FIG. 4B). The opening angle (opening / closing degree) of the slat 1a of the blind 1 is controlled so that the opening angle is controlled by normal control based on the amount of sunlight and illuminance from the start time (t2) (see FIG. 4 (b) (see (b)), for example, at the sunset (t3) when the solar radiation X disappears.

一方ステップＳ３で動作モードが”暖房”と判定された場合には、制御部１６は、在席者情報検出部１０４，情報処理部１０６を通じて取り込む在席情報が在席を示すか不在を示すかを次のステップＳ６で判定し、不在と判定した場合には、ステップＳ７において日照情報取得部１０２と、情報処理部１０６とを通じて取得した照度計４２からの各方位の鉛直面照度が予め設定している基準値以上であるのか否かの判定を行い、照度計４２の照度が基準値以上の場合には、ステップＳ８において、ブラインド１のスラット１ａを所定角度まで開く制御信号を生成してブラインド１の駆動装置を制御する。これによりブラインド１が開放状態（ステップＳ８）となって、日射Ｘが空調対象エリアＡに導入され、始業前に空調対象エリアＡの温度が日射Ｘにより上昇することになる。   On the other hand, when it is determined in step S3 that the operation mode is “heating”, the control unit 16 determines whether the presence information taken in through the presence information detecting unit 104 and the information processing unit 106 indicates presence or absence. Is determined in the next step S6, and if it is determined that the absence is present, the vertical surface illuminance in each direction from the illuminometer 42 acquired through the sunshine information acquisition unit 102 and the information processing unit 106 in step S7 is set in advance. If the illuminance of the illuminance meter 42 is equal to or greater than the reference value, a control signal for opening the slat 1a of the blind 1 to a predetermined angle is generated in step S8. 1 drive device is controlled. As a result, the blind 1 is opened (step S8), and the solar radiation X is introduced into the air-conditioning target area A, and the temperature of the air-conditioning target area A rises due to the solar radiation X before the start of work.

一方照度が基準値未満のときには制御部１０７は、ブラインド１のスラット１ａを全閉させる制御信号を生成し、ブラインド１の駆動装置（図示せず）を制御する。この場合、ブラインド１は遮蔽状態（ステップＳ９）となり、空調対象エリアＡから外部に熱が逃げるのを防ぐ。また空調対象エリアＡの窓部ｗが通りに面しているような場合に、日射量が少ない、つまり周囲が暗い状態でブラインド１を開くことによって屋内が見えるのを防いで、セキュリティ上の問題を無くしている。さて”暖房”での動作モードにおけるブラインド制御は、”冷房”の動作モード時と同様に現在時刻が始業時刻になると、ステップＳ５の通常モードへ移行し、予めプログラミングされている就業時間帯のブラインド１の制御を行うことになるが、始業時刻前であっても、ステップＳ６において在席と判定された場合にはステップＳ５へ移行する。図５（ａ）は上述の”暖房”の動作モードにおけるブラインド１の開き角度の変化を示すタイミングチャートであり、日の出（ｔ１）から始業時刻（ｔ２）までは全開状態（図５（ｂ）の（イ）参照）となるようにブラインド１のスラット１ａの開き角度が制御され、始業時刻（ｔ２）からは日照量や照度に基づいた通常制御により開き角度が制御され（図５（ｂ）の（ロ）参照）、例えば日射Ｘが無くなる日の入り時（ｔ３）には全閉される。   On the other hand, when the illuminance is less than the reference value, the control unit 107 generates a control signal for fully closing the slat 1a of the blind 1, and controls the drive device (not shown) of the blind 1. In this case, the blind 1 is in a shielded state (step S9) and prevents heat from escaping from the air-conditioning target area A to the outside. In addition, when the window part w of the air-conditioning target area A faces the street, the amount of solar radiation is small, that is, the surroundings are dark and the blind 1 is opened to prevent the indoors from being seen, which is a security problem. Is lost. As in the “cooling” operation mode, the blind control in the “heating” operation mode shifts to the normal mode in step S5 when the current time reaches the start time, and the blinds for the pre-programmed working hours are shown. However, even if it is before the start time, if it is determined that the user is present in step S6, the process proceeds to step S5. FIG. 5A is a timing chart showing a change in the opening angle of the blind 1 in the above-described “heating” operation mode, and the fully open state (from FIG. 5B) to the start time (t2) from sunrise (t1). (See (b)), the opening angle of the slat 1a of the blind 1 is controlled, and from the start time (t2), the opening angle is controlled by normal control based on the amount of sunshine and illuminance (see FIG. 5B). (See (b)), for example, at the time of sunset (t3) when the solar radiation X disappears.

以上のように本実施形態では、始業前に空調装置３ｂの動作モードに応じてブラインド１のスラット１ａの角度を制御することにより、始業前において空調対象エリアＡへの日射Ｘの入り込みを制御し、始業時刻に空調装置３ｂの起動際の消費エネルギを削減し、省エネルギ化が図れることになる。尚本実施形態では、上述のようにステップＳ２において日の出判定に閾値と日射量との比較を用いているが、太陽位置のみで判定するようにしても良い。   As described above, in this embodiment, by controlling the angle of the slat 1a of the blind 1 according to the operation mode of the air conditioner 3b before the start of work, the entry of the solar radiation X into the air-conditioning target area A is controlled before the start of work. The energy consumption when starting the air conditioner 3b at the start time can be reduced to save energy. In the present embodiment, as described above, the comparison between the threshold value and the amount of solar radiation is used for the sunrise determination in step S2, but the determination may be made based only on the sun position.

ところで、上述の場合では、人検知センサ１０５としては例えば赤外線等の人感センサを用いて空調対象エリアＡ内の人の存否（在席／不在）を検知していたが、人が執務（作業）を行っている場合にのみ通常制御へ移行するようにして、執務（作業）状態でないのに空調装置３ｂを動かすことによる無駄なエネルギ消費を防ぐようにしても良い。この場合、人検知センサ１０５として撮像カメラにより人の動きを検知し、執務（作業）状態にあるか否かを判断する手段、或いは執務者が机上のコンピュータを立ち上げたことを検知する手段、椅子に座ったことで執務（作業）状態に入ることを検知する手段等を人検知センサ１０５として設け、これらの手段から出力される人検知信号、つまり執務（作業）状態の検知信号の有無をステップＳ６で判定し、検知信号があったときにステップＳ５へ移行するようにする。
