以下、図面を参照して本発明の室内圧力制御システム及び室内圧力制御方法の一実施形態を説明する。図１に示すように、本実施形態では、屋外汚染物質に対する対応について説明する。１は室内圧力制御システム、２は空気浄化装置、３は空調ＰＡＣ、４は通常時給気ダンパ、３０は室内圧力変更手段、３１は仕切、Ａは室、Ａ１は陽圧対象エリアである。なお、この場合の室内圧力変更手段３０は、仕切３１のことである。   Hereinafter, an embodiment of an indoor pressure control system and an indoor pressure control method of the present invention will be described with reference to the drawings. As shown in FIG. 1, in the present embodiment, a response to an outdoor contaminant will be described. 1 is an indoor pressure control system, 2 is an air purifier, 3 is an air conditioning PAC, 4 is a normal air supply damper, 30 is an indoor pressure changing means, 31 is a partition, A is a room, and A1 is a positive pressure target area. In this case, the indoor pressure changing means 30 is a partition 31.

室内圧力制御システム１は、フィルタを有する空気浄化装置２、空調ＰＡＣ３、通常時給気ダンパ４及び室内圧力変更手段３０等を備えている。通常時は、空気浄化装置２、空調ＰＡＣ３及び通常時給気ダンパ４を作動し、運転している。室内圧力変更手段３０は、化学工場等の事故による汚染、火山性爆発によるガス汚染、核関連物質、生物・化学剤等の不意な事故等が起こった場合の緊急時に室Ａ内の陽圧対象エリアＡ１の圧力を上昇させるものである。本実施形態では、陽圧対象エリアＡ１の容積を削減する仕切３１を有する。   The indoor pressure control system 1 includes an air purification device 2 having a filter, an air conditioning PAC3, a normal-time air supply damper 4, an indoor pressure changing means 30, and the like. In normal times, the air purification device 2, the air conditioning PAC3, and the normal-time air supply damper 4 are operated and operated. The room pressure changing means 30 is subject to positive pressure in the room A in case of emergency in the event of accidents such as chemical factory accidents, gas pollution due to volcanic explosions, nuclear related substances, biological / chemical agents, etc. The pressure in area A1 is increased. In this embodiment, it has the partition 31 which reduces the volume of positive pressure object area A1.

図２は、本実施形態の室内圧力制御システムのブロック図を示す。図２において、１０は入力手段、１１は入力手段１０の一例としてのセンサ、１２は入力手段１０の一例としての受信装置、２０は制御部、３０は室内圧力変更手段、３１は室内圧力変更手段３０の一例としての仕切、４０は警報手段である。   FIG. 2 shows a block diagram of the indoor pressure control system of the present embodiment. In FIG. 2, 10 is an input means, 11 is a sensor as an example of the input means 10, 12 is a receiving device as an example of the input means 10, 20 is a control unit, 30 is an indoor pressure changing means, and 31 is an indoor pressure changing means. A partition 30 as an example, 40 is an alarm means.

センサ１１は外部の汚染状況を検知するもので、自動車の排気ガス等の通常汚染、化学工場・火山性ガス等の特定物質等の周囲に対応した特定の汚染のみを検知するものでもよい。受信装置１２は火山警報等の緊急時の警報等を受信するものである。センサ１１及び受信装置１２は共に２４時間連続で不意の外部汚染に備えることができるものが好ましいが、人の入退出管理が厳密に行われている箇所等では、勤務時間又は室内滞在時間のみにセンシング又は受信するようにしてもよい。制御部２０は、入力手段１０からの信号を入力として、室内圧力変更手段３０を制御するものである。室内圧力変更手段３０は、本実施形態では、仕切３１を有し、部屋の大きさを小さくすることで、吸気量や排気量を変更しなくても室内の圧力を上昇できるものである。警報手段４０は、避難者を陽圧対象室Ａ１へ案内するための音声警報手段や表示警報手段等を含み、避難者を誘導するものである。   The sensor 11 detects an external pollution state, and may detect only a specific pollution corresponding to the surroundings of a normal substance such as an automobile exhaust gas and a specific substance such as a chemical factory and a volcanic gas. The receiving device 12 receives an emergency warning such as a volcano warning. Both the sensor 11 and the receiving device 12 are preferably capable of preparing for unexpected external contamination for 24 hours in a row, but in places where human entry / exit management is strictly performed, only the working hours or the staying time in the room. Sensing or reception may be performed. The control unit 20 controls the indoor pressure changing unit 30 with the signal from the input unit 10 as an input. In this embodiment, the indoor pressure changing means 30 has a partition 31 and can reduce the size of the room so that the indoor pressure can be increased without changing the intake air amount or the exhaust air amount. The warning means 40 includes a voice warning means and a display warning means for guiding the refugee to the positive pressure target room A1, and guides the refugee.

このような、構造の室内圧力制御システムの作動について説明する。通常時、外気は空気浄化装置２で浄化され、空気ＰＡＣ３により温度を調整され、通常給気ダンパ４により流量を調整されて室Ａに空気を供給している。   The operation of the indoor pressure control system having such a structure will be described. During normal times, the outside air is purified by the air purifier 2, the temperature is adjusted by the air PAC 3, the flow rate is adjusted by the normal air supply damper 4, and air is supplied to the chamber A.

外部の汚染状況を検知するセンサ１１又は緊急時の警報等を受信する受信装置１２等の入力手段１０により緊急時であることが制御部２０に入力されると、仕切３１により室Ａは、陽圧対象エリアＡ１とそうでない部分とに分割され容積を小さくし、陽圧対象エリアＡ１の室圧を要求室圧にする。要求圧力によっては、仕切３１による分割だけを行うが、より高い要求圧力の場合、給気量を上昇させ、排気量を削減又は排気を停止してもよい。また、周囲風速等により給気量や排気量を制御してもよい。さらに、制御部２０により、図示しない窓や扉等を自動的に閉状態に制御してもよい。   When an emergency state is input to the control unit 20 by an input means 10 such as a sensor 11 that detects an external contamination state or a receiving device 12 that receives an emergency alarm or the like, the room 31 becomes positive by the partition 31. The pressure is divided into the pressure target area A1 and the portion that is not so as to reduce the volume, and the chamber pressure in the positive pressure target area A1 is set to the required chamber pressure. Depending on the required pressure, only division by the partition 31 is performed, but in the case of a higher required pressure, the supply amount may be increased, the exhaust amount may be reduced, or the exhaust may be stopped. Further, the air supply amount and the exhaust amount may be controlled by the ambient wind speed or the like. Furthermore, you may control the window, door, etc. which are not shown in figure to a closed state automatically by the control part 20. FIG.

このような室内圧力制御システム１を適用することにより、屋外汚染物質の室内への侵入を防止することができる。   By applying such an indoor pressure control system 1, it is possible to prevent the entry of outdoor pollutants into the room.

図３は、第２の実施形態として、仕切３１に代えて、袋状部材３２、第１緊急時給気ダンパ３３及び第２緊急時給気ダンパ３４等を適用したものである。袋状部材３２は、通常時には壁や天井等の中に隠され、緊急時に膨張し、陽圧対象エリアＡ１の容積を削減するものである。また、第１緊急時給気ダンパ３３、第２緊急時給気ダンパ３４は、緊急時に袋状部材３２に給気するために開くダンパであり、第１緊急時給気ダンパ３３は、通常時に使用している給気系統と連結されたもので、第２緊急時給気ダンパ３４は、通常時に使用していない別の給気系統と連結されたものである。   FIG. 3 shows a second embodiment in which a bag-like member 32, a first emergency air supply damper 33, a second emergency air supply damper 34, and the like are applied in place of the partition 31. The bag-like member 32 is normally concealed in a wall, a ceiling or the like, and expands in an emergency to reduce the volume of the positive pressure target area A1. The first emergency air supply damper 33 and the second emergency air supply damper 34 are dampers that are opened to supply air to the bag-like member 32 in an emergency, and the first emergency air supply damper 33 is used during normal times. The second emergency air supply damper 34 is connected to another air supply system that is not normally used.

図４は、第２実施形態のブロック図である。図４において、３２は室内圧力変更手段３０の一例としての袋状部材、３３は室内圧力変更手段３０の一例としての第１緊急時給気ダンパ、３４は室内圧力変更手段３０の一例としての第２緊急時給気ダンパ、その他は第１実施形態と共通である。   FIG. 4 is a block diagram of the second embodiment. In FIG. 4, 32 is a bag-like member as an example of the indoor pressure changing means 30, 33 is a first emergency air supply damper as an example of the indoor pressure changing means 30, and 34 is a second as an example of the indoor pressure changing means 30. The emergency air supply damper and others are common to the first embodiment.

このような構造の第２実施形態の作動は、入力手段１０に関しては、第１実施形態と共通であり、その後、常閉の第１緊急時給気ダンパ３３及び第２緊急時給気ダンパ３４が開き、袋状部材３２が膨張することにより、室Ａは、陽圧対象エリアＡ１の容積を小さくし、陽圧対象エリアＡ１の室圧を要求室圧にする。要求圧力によっては、仕切３１による分割だけを行うが、より高い要求圧力の場合、排気量を削減又は排気を停止してもよい。また、周囲風速等により給気量や排気量を制御してもよい。通常、周囲風速が高いほど、室内の陽圧を上げる必要がある。さらに、制御部２０により、図示しない窓や扉等を自動的に閉状態に制御してもよい。   The operation of the second embodiment having such a structure is the same as that of the first embodiment with respect to the input means 10, and thereafter the normally closed first emergency air supply damper 33 and the second emergency air supply damper 34 are opened. As the bag-like member 32 expands, the chamber A reduces the volume of the positive pressure target area A1 and sets the chamber pressure of the positive pressure target area A1 to the required chamber pressure. Depending on the required pressure, only division by the partition 31 is performed, but if the required pressure is higher, the exhaust amount may be reduced or the exhaust may be stopped. Further, the air supply amount and the exhaust amount may be controlled by the ambient wind speed or the like. Usually, the higher the ambient wind speed, the higher the indoor positive pressure must be. Furthermore, you may control the window, door, etc. which are not shown in figure to a closed state automatically by the control part 20. FIG.

なお、仕切３１及び袋状部材３２は、第３の実施形態として、図５に示すように、袋状部材３２により仕切３１を作動させるように、両者協同して適用してもよい。   As shown in FIG. 5, the partition 31 and the bag-like member 32 may be applied in cooperation so that the partition 31 is operated by the bag-like member 32 as shown in FIG. 5.

次に、具体的な室内陽圧の設定について説明する。表１は、汚染状況による室内陽圧を示すものである。   Next, specific setting of the indoor positive pressure will be described. Table 1 shows the indoor positive pressure depending on the contamination status.

Figure 2008164178

このように、本実施形態では、緊急時レベルが上がると、表１のように設定を切り換えて運転する。緊急時レベルとしては、屋外汚染物質の飛散状況や風速等により設定し、入力手段１０により検知し、制御部２０がどのレベルか判断するとよい。なお、本表内の数値はあくまでも目安であり、状況に合わせて他の数値を設定してもよい。また、本表では、３クラスとしているが、クラスの数はいくつに設定してもよい。
Figure 2008164178
Thus, in this embodiment, when the emergency level increases, the setting is switched as shown in Table 1 for operation. As an emergency level, it is good to set by the scattering state of an outdoor pollutant, a wind speed, etc., to detect with the input means 10, and to determine which level the control part 20 has. Note that the numerical values in this table are only a guide, and other numerical values may be set according to the situation. In this table, although there are three classes, any number of classes may be set.

図６は、他の実施形態を示す図である。本実施形態では、袋状部材１３２内部を陽圧対象エリアＡ１としたものであり、緊急時には、第１緊急時バルブ１３３を開き、天井や壁面から袋状部材１３２を出現させて濾過空気により膨張させ、袋状部材１３２に扉等を設けて、人はその中に入ることとする。この場合にも袋状部材１３２と仕切３１を両者協同して作動させてよい。   FIG. 6 is a diagram showing another embodiment. In the present embodiment, the inside of the bag-shaped member 132 is the positive pressure target area A1, and in an emergency, the first emergency valve 133 is opened, and the bag-shaped member 132 appears from the ceiling or wall surface and is expanded by filtered air. The bag-like member 132 is provided with a door or the like, and a person enters it. Also in this case, the bag-like member 132 and the partition 31 may be operated in cooperation with each other.

また、その他の実施形態として、入力手段として室内汚染状況を検知するセンサを有し、センサにより入力された室内汚染状況に応じて室内圧力変更手段により室Ａの周囲の圧力を上昇させて、室内汚染物質の屋外への拡散を防止するように設定してもよい。例えば、室Ａの汚染源を袋状部材で覆い、室Ａの内部で袋状部材の外部の圧力を上昇させる。このような室内圧力制御システム１を適用すると、室内汚染物質の屋外への拡散を防止することができる。   Further, as another embodiment, a sensor for detecting the indoor contamination status is provided as the input means, and the pressure around the room A is increased by the indoor pressure changing means in accordance with the indoor contamination status input by the sensor. It may be set to prevent the diffusion of pollutants to the outdoors. For example, the contamination source of the chamber A is covered with a bag-shaped member, and the pressure outside the bag-shaped member is increased inside the chamber A. When such an indoor pressure control system 1 is applied, it is possible to prevent indoor pollutants from diffusing outdoors.
