　特許文献１に記載された技術は、湿気、二酸化炭素、室内汚染物質等を屋外（建築物の外部）に排出する機能を有している。しかしながら、吸気用の換気扇を通して屋外の汚染物質が室内（建築物の部屋の内部）に導入される可能性についての配慮がない。 The technology described in Patent Document 1 has a function of discharging moisture, carbon dioxide, indoor pollutants and the like to the outside (outside a building). However, there is no consideration about the possibility that outdoor pollutants are introduced into the room (inside the building room) through the intake fan.
　本発明は、機械換気により室内の空気質を清浄に維持するために、換気に用いる装置を制御する制御装置を提供することを目的とする。さらに、本発明は、この制御装置を用いた通風制御システム、およびコンピュータを制御装置として機能させるためのプログラムを提供することを目的とする。 An object of the present invention is to provide a control device for controlling a device used for ventilation in order to maintain room air quality clean by mechanical ventilation.

　本発明の一態様に係る制御装置は、室内の空気質を計測する第１の空気質センサおよび室外の空気質を計測する第２の空気質センサから計測値を取得する取得部と、空気質を改善するフィルタを通して前記室外から前記室内に吸気すると同時に前記室内から前記室外への排気を行う第１の状態と、前記室内から前記室外への排気を行う第２の状態とを選択するように換気装置に動作の指示を行う指示部と、前記計測値に基づいて前記指示部により行われる前記指示の内容を定める処理部とを備え、前記処理部は、前記第２の空気質センサが計測した前記計測値が所定の閾値に対して非清浄側である場合には、前記第１の状態で前記換気装置を運転させ、前記第２の空気質センサが計測した前記空気質が前記閾値に対して清浄側である場合には、前記第２の状態で前記換気装置を運転させるように前記指示の内容を定める。 A control device according to one aspect of the present invention includes an acquisition unit that acquires measurement values from a first air quality sensor that measures indoor air quality and a second air quality sensor that measures outdoor air quality; The first state in which air is exhausted from the room to the outside at the same time as the air is sucked into the room from the outside through the filter for improving the second state, and the second state in which the air is exhausted from the room to the outside And a processing unit that determines the content of the instruction performed by the instruction unit based on the measurement value, and the processing unit measures the second air quality sensor If the measured value is on the non-clean side with respect to a predetermined threshold value, the ventilation device is operated in the first state, and the air quality measured by the second air quality sensor is equal to the threshold value. When it is on the clean side , It defines the contents of the instruction so as to operate the ventilator in the second state.
　本発明の一態様に係る通風制御システムは、制御装置と、換気装置と備え、前記換気装置は、室外から空気質を改善するフィルタを通して室内に吸気すると同時に前記室内から前記室外への排気を行う第１の状態と、前記室内から前記室外への排気を行う第２の状態とが選択可能である。 A ventilation control system according to an aspect of the present invention includes a control device and a ventilating device, wherein the ventilating device sucks air into the room through a filter for improving air quality from the outside and simultaneously exhausts the room from the room. A first state and a second state in which the room is exhausted to the outside can be selected.
　本発明の一態様に係るプログラムは、コンピュータを、制御装置として機能させるためのものである。 A program according to an aspect of the present invention is for causing a computer to function as a control device.
　本発明の構成によれば、室外の空気質が清浄であれば室内の空気を室外に排気することにより、室外の空気を室内に取り入れ、室外の空気質が非清浄であれば室内の空気を室外に排気するだけではなく、フィルタを通して室外の空気を室内に取り入れる。この構成によって、室外の空気質に応じて機械換気の経路を切り替えることができ、室内の空気質を清浄に維持することが可能になる。 According to the configuration of the present invention, if the outdoor air quality is clean, the outdoor air is taken into the room by exhausting the indoor air to the outdoor, and if the outdoor air quality is not clean, the indoor air is clean. In addition to exhausting the air outdoors, the air outside the room is taken into the room through the filter. According to this configuration, it is possible to switch the path of mechanical ventilation according to the air quality outside, and it is possible to keep the air quality inside the room clean.

　以下、実施形態として、建築物の部屋の内部（室内）における空気質を清浄に維持するために、換気に用いる装置を制御する制御装置、および、この制御装置を含む通風制御システムについて説明する。なお、その建築物が住宅である場合（室内が住宅の居室内である場合）を想定して説明するが、その建築物は、店舗、オフィス、病院その他の施設であってもよい。また、住宅は、戸建て住宅と集合住宅とのどちらでもよい。ここで、換気は、基本的には建築物の部屋の内側（屋内における室内）と建築物の外側（屋外）との間での換気を想定して説明する。しかし、建築物の内部空間において、特定の部屋（屋内における室内）とその部屋の外部（屋内における室外）の換気であっても、本実施形態で示す技術を適用し得る。 Hereinafter, as an embodiment, a control device for controlling a device used for ventilation and a ventilation control system including the control device will be described in order to maintain clean air quality inside a room of a building (indoor). In addition, although the case where the building is a house (when an indoor is a living room of a house) is explained and explained, the building may be a store, an office, a hospital, and other facilities. Also, the house may be either a detached house or an apartment house. Here, ventilation is basically described on the assumption of ventilation between the inside of a room of a building (indoor indoor) and the outside of a building (outdoor). However, in the interior space of a building, the technique described in this embodiment can be applied even to ventilation of a specific room (indoor indoor) and the outside of the room (outdoor indoor).
　本実施形態に係る通風制御システム１は、図１に示すように、住宅の部屋４０における空気質を清浄に維持するためのシステムであり、制御装置１０および換気装置２１を備える。 The ventilation control system 1 according to the present embodiment is a system for keeping the air quality in the room 40 of a house clean as shown in FIG. 1 and includes a control device 10 and a ventilation device 21.
　図１の例では、部屋４０には、室内４１と室外４２との間で空気を流通させる装置（換気に用いる装置）として、換気装置２１の他に、通気装置２２とレンジフード２３とが設けられている。レンジフード２３はキッチンに配置される。ただし、本実施形態で説明する部屋４０は、キッチンあるいはキッチンが併設されたリビング等である場合に限らず、建築物（住宅等）の中でキッチンと連続した空間であり、かつレンジフード２３で空気流を形成することができる空間であればよい。レンジフード２３は、室内４１から室外４２へ排気を行う排気用換気扇の一例である。部屋４０が、キッチンでなく、キッチンに連続していない部屋であっても、排気用換気扇が換気装置２１とは別に配置されていれば、通風制御システム１により、以下に説明する動作（部屋内の空気質を維持するように換気を行う動作）がなされ得る。なお、排気用換気扇は、レンジフード２３のように流量の比較的大きい換気扇であることが有効であるが、流量が大きくなくてもよい。 In the example of FIG. 1, the room 40 is provided with a ventilation device 22 and a range hood 23 in addition to the ventilation device 21 as a device (a device used for ventilation) for circulating air between the indoor 41 and the outdoor 42. It is done. The range hood 23 is disposed in the kitchen. However, the room 40 described in the present embodiment is not limited to a living room or the like with a kitchen or a kitchen, and is a space continuous with the kitchen in a building (e.g. a house) and the range hood 23 It may be a space that can form an air flow. The range hood 23 is an example of a ventilating fan for exhausting air from the room 41 to the outside 42. Even if the room 40 is not a kitchen but a room not connected to a kitchen, if the exhaust ventilation fan is disposed separately from the ventilation device 21, the operation described below (in the room by the ventilation control system 1) Ventilation can be done to maintain the air quality of the Although it is effective that the exhaust ventilation fan is a ventilation fan having a relatively large flow rate like the range hood 23, the flow rate may not be large.
　室内４１には、室内４１の空気質を計測する空気質センサ３１、温度と湿度とを計測する温湿度センサ３３が配置され、室外４２には、室外４２の空気質を計測する空気質センサ３２が配置される。さらに、図１の例では、室内４１に空気清浄機２４が配置されている。なお、図１に示す配置例は一例であり、部屋４０の構成に応じて、配置は適宜に変更される。また、空気清浄機２４は必須ではない。 An air quality sensor 31 for measuring the air quality of the room 41, and a temperature and humidity sensor 33 for measuring the temperature and humidity are disposed in the room 41, and an air quality sensor 32 for measuring the air quality of the room 42 outside the room 42. Is placed. Furthermore, in the example of FIG. 1, the air cleaner 24 is disposed in the room 41. Note that the arrangement example shown in FIG. 1 is an example, and the arrangement is appropriately changed according to the configuration of the room 40. Also, the air cleaner 24 is not essential.
　換気装置２１、通気装置２２およびレンジフード２３は、制御装置１０から動作の指示を受ける。また、制御装置１０は、空気質センサ３１、温湿度センサ３３および空気質センサ３２から入力される情報を用いて、換気装置２１、通気装置２２およびレンジフード２３に対する指示の内容を定める制御処理を行う。なお、通風制御システム１は、制御装置１０および換気装置２１のみならず、図１に示す他の１以上の装置、センサ等を含み得る。 The ventilation device 21, the ventilation device 22 and the range hood 23 receive an operation instruction from the control device 10. Further, the control device 10 performs control processing to determine the content of the instruction to the ventilation device 21, the ventilation device 22 and the range hood 23 using the information input from the air quality sensor 31, the temperature and humidity sensor 33 and the air quality sensor 32. Do. The ventilation control system 1 may include not only the control device 10 and the ventilation device 21 but also one or more other devices, sensors, etc. shown in FIG.
　換気装置２１は、ハウジング２１０に、吸気用の流路２１１と排気用の流路２１２とを備える。吸気用の流路２１１には吸気用のファン２１３が配置され、排気用の流路２１２には排気用のファン２１４が配置される。さらに、吸気用の流路２１１には、空気質を改善するフィルタ２１５が配置される。したがって、吸気用の流路２１１を通して室外４２から室内４１に導入される空気は、フィルタ２１５により空気質が室外４２よりも改善される。 The ventilation device 21 includes a flow path 211 for intake and a flow path 212 for exhaust in the housing 210. An intake fan 213 is disposed in the intake channel 211, and an exhaust fan 214 is disposed in the exhaust channel 212. Furthermore, a filter 215 for improving air quality is disposed in the intake flow path 211. Therefore, the air quality of the air introduced from the outside room 42 to the room 41 through the air flow path 211 is improved by the filter 215 compared to the room 42 outside.
　フィルタ２１５が除去の対象とする空気質の因子は、粒子状物質、花粉、黄砂等である。粒子状物質は、ＰＭ２．５（ＰＭ：Particulate Matter）として知られる微小粒子状物質を想定しているが、浮遊粒子状物質、ＰＭ１０等でもよい。フィルタ２１５は、吸気用の流路２１１において、吸気用のファン２１３に対する空気の導入側に配置されていることが望ましい。 Factors of air quality to be removed by the filter 215 are particulate matter, pollen, yellow sand and the like. The particulate matter is assumed to be a fine particulate matter known as PM2.5 (PM: Particulate Matter), but may be suspended particulate matter, PM10 or the like. It is desirable that the filter 215 be disposed on the air introduction side with respect to the suction fan 213 in the suction flow path 211.
　換気装置２１は、制御装置１０からの指示を受けて、排気用のファン２１４と同時に吸気用のファン２１３を運転する第１の状態と、排気用のファン２１４のみを運転する第２の状態とが選択可能になっている。第１の状態は第１種換気（機械で吸気および排気を行う方式での換気）に相当し、第２の状態は第３種換気（機械で排気を行い通気口等で自然に吸気する方式での換気）に相当する。言い換えると、換気装置２１は、制御装置１０からの指示によって、第１種換気と第３種換気とを選択するように構成されている。 In response to an instruction from the control device 10, the ventilation device 21 operates in a first state in which the fan 214 for suction is operated simultaneously with the fan 214 for exhaust, and in a second state in which only the fan 214 for exhaust is operated. Is selectable. The first state corresponds to type 1 ventilation (ventilation with a mechanical intake and exhaust system), and the second state is a type 3 ventilation (natural exhaust with a machine vent and air intake with a mechanical vent) Equivalent to ventilation in In other words, the ventilator 21 is configured to select the type 1 ventilation and the type 3 ventilation according to an instruction from the control device 10.
　なお、換気装置２１は、吸気用のファン２１３のみを運転する第２種換気（機械で吸気を行い通気口等で自然に排気する方式での換気）の状態が選択可能であってもよいが、本実施形態に係る通風制御システム１では採用していない。また、換気装置２１は、吸気用の流路２１１と排気用の流路２１２との一方を使用しない場合に遮断できるように、流路２１１および流路２１２は、それぞれダンパ（damper）またはバルブ（valve）を備えていることが望ましい。 In addition, the ventilator 21 may be able to select the state of type 2 ventilation (ventilation in a system in which suction is performed by a machine and exhausted naturally by an air vent etc.) in which only the fan 213 for suction is operated. The ventilation control system 1 according to the present embodiment is not employed. Further, the flow path 211 and the flow path 212 may be respectively provided with dampers or valves (valves) so that the ventilation device 21 can shut off when one of the flow path 211 for intake and the flow path 212 for exhaust is not used. It is desirable to have a
　上述したように、換気装置２１は、第１の状態で運転している期間には、室外４２からフィルタ２１５を通して室内４１に吸気すると同時に、室内４１から室外４２への排気を行う。また、換気装置２１は、第２の状態で運転している期間には、室内４１から室外４２への排気のみを行う。 As described above, during the operation in the first state, the ventilation device 21 sucks air from the outside room 42 through the filter 215 into the room 41 and at the same time exhausts the room 41 to the outside room 42. In addition, the ventilation device 21 performs only the exhaust from the room 41 to the outside 42 during the operation in the second state.
　第１の状態と第２の状態とは、吸気用のファン２１３と排気用のファン２１４とをハウジング２１０に備える換気装置２１に限らず、個々のハウジングを備えた吸気用の換気扇と排気用の換気扇とを組み合わせることによって実現することが可能である。すなわち、換気装置２１は、吸気と排気とを１台で同時に行う構成に限らず、吸気と排気とを個々に行う複数台の換気扇で実現されてもよい。 The first state and the second state are not limited to the ventilating apparatus 21 having the housing 210 with the intake fan 213 and the exhaust fan 214 in the housing 210, and the intake fan and the exhaust fan having the individual housings. It can be realized by combining with a ventilation fan. That is, the ventilator 21 is not limited to a configuration in which intake and exhaust are simultaneously performed by one unit, and may be realized by a plurality of ventilators that individually perform intake and exhaust.
　レンジフード２３は、室内４１から排気のみを行う装置であり、本実施形態では、換気装置２１による換気を補助する装置として用いられる。後述するように、室内４１から急速に排気を行う場合には、換気装置２１における排気用のファン２１４とレンジフード２３とを同時に運転する状態が選択される。この動作の際に室内４１の空気を迅速に排気するために、換気装置２１は、部屋４０において、レンジフード２３に対して離れて配置されていることが望ましい。 The range hood 23 is a device that only exhausts air from the room 41, and in the present embodiment, is used as a device that assists ventilation by the ventilation device 21. As described later, when exhausting air from the room 41 rapidly, a state in which the exhaust fan 214 and the range hood 23 in the ventilation device 21 are simultaneously operated is selected. In order to quickly exhaust the air in the room 41 during this operation, it is desirable that the ventilating device 21 be disposed apart from the range hood 23 in the room 40.
　通気装置２２は、部屋４０の窓のような開口部に配置されるか、部屋４０の壁を貫通するように配置される。通気装置２２は、室内４１と室外４２との間で空気の流通を可能にする流路２２１（通気口）が形成されている。また、通気装置２２は、流路２２１を通して室内４１と室外４２との間で空気の流通を許可する状態（自然に換気する状態）と、空気の流通を遮断する状態とを選択するために、ダンパまたはバルブのような開閉装置２２２を備えている。開閉装置２２２は、制御装置１０からの指示を受けて空気の流通を許可する状態と空気の流通を遮断する状態とを選択する。通気装置２２を開くこと、つまり開閉装置２２２を開くことで、空気の流通が可能となり自然に換気がなされる状態となり、通気装置２２を閉じる、つまり開閉装置２２２を閉じることで、空気の流通が遮断され換気できない状態となる。 The venting device 22 is disposed at an opening such as a window of the room 40 or is arranged to penetrate the wall of the room 40. The ventilation device 22 is formed with a flow path 221 (air vent) that allows air to flow between the indoor 41 and the outdoor 42. In addition, the ventilation device 22 selects the state of permitting the flow of air between the room 41 and the outside 42 through the flow path 221 (the state of natural ventilation) and the state of blocking the flow of air. A switching device 222 such as a damper or valve is provided. In response to an instruction from the control device 10, the opening / closing device 222 selects the state of permitting the flow of air and the state of blocking the flow of air. By opening the venting device 22, that is, opening the switching device 222, air can be distributed and naturally ventilated, and by closing the venting device 22, that is, closing the switching device 222, the flow of air can be achieved. It is shut off and can not ventilate.
　室内４１に配置された空気質センサ３１は、粒子状物質（とくにＰＭ２．５）と二酸化炭素と臭気成分とを、空気質の因子として濃度を計測する。この空気質センサ３１は、花粉、黄砂、ほこり、カビの胞子、ダニ等についても粒子状物質と区別することなく濃度を計測する。また、室外４２に配置された空気質センサ３２は、主として粒子状物質の濃度を計測する。 The air quality sensor 31 disposed in the room 41 measures the concentration of particulate matter (especially PM 2.5), carbon dioxide and an odor component as factors of air quality. The air quality sensor 31 measures the concentration of pollen, yellow sand, dust, mold spores, mites and the like without distinction from particulate matter. The air quality sensor 32 disposed outside the room 42 mainly measures the concentration of particulate matter.
　空気質センサ３１および空気質センサ３２が計測の対象とする空気質の因子は、上述した例に限らないが、室内４１の空気質センサ３１と室外４２の空気質センサ３２とのどちらも、粒子状物質の濃度は共通の因子として計測することが望ましい。また、室内４１の空気質を清浄に維持（あるいは室内４１を快適かつ安心できる空気環境に維持）するために、計測対象の因子の種類は、室内４１の空気質センサ３１の方が室外４２の空気質センサ３２より多くなり得る。 The factors of air quality to be measured by the air quality sensor 31 and the air quality sensor 32 are not limited to the above-described example, but both the air quality sensor 31 in the room 41 and the air quality sensor 32 in the outdoor room 42 are particles It is desirable to measure the concentration of the substance as a common factor. In order to keep the air quality of the room 41 clean (or maintain the room 41 in a comfortable and reliable air environment), the type of factor to be measured is that the air quality sensor 31 in the room 41 is outside the room 42 There may be more air quality sensors 32.
　空気質の複数種類の因子に関して計測を行う場合、空気質の因子ごとに空気質センサ３１を配置してもよい。たとえば、空気質センサ３１として、粒子状物質の濃度を計測する空気質センサと、二酸化炭素の濃度を計測する空気質センサとを備えていてもよい。また、二酸化炭素の濃度を計測する空気質センサは、臭気成分（たとえば、ホルムアルデヒド、特定の種類の揮発性有機化合物（ＶＯＣ：Volatile Organic Compounds）、メルカプタン等）も計測可能となるように構成されていてもよい。 When measuring with respect to a plurality of air quality factors, the air quality sensor 31 may be disposed for each air quality factor. For example, the air quality sensor 31 may include an air quality sensor that measures the concentration of particulate matter, and an air quality sensor that measures the concentration of carbon dioxide. In addition, an air quality sensor that measures the concentration of carbon dioxide is configured to be able to measure odorous components (for example, formaldehyde, volatile organic compounds (VOC: volatile organic compounds), mercaptan, etc.) May be
　温湿度センサ３３は、室外４２の空気を室内４１に導入する際に、室内４１の温度および湿度の変化を監視するために設けられている。温湿度センサ３３が計測した室内４１の温度および湿度が、あらかじめ定められた快適な範囲を逸脱する場合には、機械換気を行わずに、空調装置（不図示）により室内４１の温度の調節を行い、また必要に応じて空気清浄機２４による空気質の改善を行う。空気清浄機２４は、粒子状物質の除去と臭気成分の除去とが可能になっており、また、室内４１において空気を循環させる機能を有する。 The temperature and humidity sensor 33 is provided to monitor changes in the temperature and humidity of the room 41 when introducing the air outside the room 42 into the room 41. If the temperature and humidity of the room 41 measured by the temperature and humidity sensor 33 deviate from a predetermined comfortable range, the temperature of the room 41 is adjusted by an air conditioner (not shown) without mechanical ventilation. And, if necessary, improve the air quality with the air cleaner 24. The air cleaner 24 is capable of removing particulate matter and removing odorous components, and has a function of circulating air in the room 41.

　処理部１２は、取得部１１から受け取った計測値を用いて換気装置２１、通気装置２２、レンジフード２３および空気清浄機２４への指示の内容を定める。処理部１２は、メモリに格納されたプログラムを実行するプロセッサ、メモリ等により実現される。 The processing unit 12 uses the measurement values received from the acquisition unit 11 to determine the content of the instruction to the ventilation device 21, the ventilation device 22, the range hood 23, and the air cleaner 24. The processing unit 12 is realized by a processor that executes a program stored in the memory, a memory, and the like.
　指示部１３は、処理部１２が定めた指示を受けて、その指示を換気装置２１、通気装置２２、レンジフード２３、空気清浄機２４に与える。指示部１３は、メモリに格納されたプログラムを実行するプロセッサ、通信Ｉ／Ｆ等により実現される。 The instruction unit 13 receives the instruction determined by the processing unit 12 and gives the instruction to the ventilation device 21, the ventilation device 22, the range hood 23, and the air cleaner 24. The instruction unit 13 is realized by a processor that executes a program stored in the memory, a communication I / F, and the like.
　以下に説明する動作では、温湿度センサ３３は用いていない。温湿度センサ３３の計測値を用いると、たとえば、夏季では室外４２の気温が室内４１の気温よりも高い期間、また冬季では室外４２の気温が室内４１の気温よりも低い期間に、換気を行わないという選択が可能になる。以下では、処理部１２が、空気質に関する計測値のみを用いて、換気装置２１、通気装置２２、レンジフード２３、空気清浄機２４に与える指示を定める例について説明する。 The temperature and humidity sensor 33 is not used in the operation described below. Using the measurement value of the temperature and humidity sensor 33, for example, ventilation is performed in a period when the temperature of the outdoor 42 is higher than the temperature of the indoor 41 in summer and during the period when the temperature of the outdoor 42 is lower than the temperature of the indoor 41 in winter. It is possible to choose not to. Hereinafter, an example will be described in which the processing unit 12 determines an instruction given to the ventilating device 21, the ventilating device 22, the range hood 23, and the air cleaner 24 using only the measurement value related to the air quality.
　上述したように室内４１に配置された空気質センサ３１は、粒子状物質の濃度と、二酸化炭素の濃度および臭気成分の濃度とを監視する。また、室外４２に配置された空気質センサ３２は粒子状物質の濃度を監視する。処理部１２には、空気質センサ３１の計測値と比較される閾値が空気質の因子ごとに定められており、また、空気質センサ３２の計測値と比較される閾値が定められている。空気質センサ３１および空気質センサ３２の計測値と比較される閾値は、空気質センサ３１または空気質センサ３２の計測値が閾値よりも大きいときに空気質が非清浄と判定されるように設定される。言い換えると、計測値が閾値以下であれば空気質は清浄と判定される。つまり、室内４１に配置された空気質センサ３１の計測値が閾値を超えることは、室内４１の空気を清浄化することが必要であることを意味する。計測値と閾値との大小比較により空気質が清浄か非清浄かを判定する際に、比較結果として清浄と判定される計測値は、閾値に対して清浄側にあり、比較結果として非清浄と判定される計測値は、閾値に対して非清浄側にあると表現する。上述の例では、計測値が、閾値より大きいと清浄側にあり閾値以下であると非清浄側にあることになるが、他の例として、計測値が閾値以上であると清浄側にあり、閾値未満であると非清浄側にあるように判定すること等も可能である。処理部１２は、室内４１に配置された空気質センサ３１が複数の因子について濃度の計測を行う場合において、例えば、１つ以上の因子についての計測値が設定されている閾値を超えた場合に、室内４１の空気質が非清浄であると判定し、全ての因子についての計測値それぞれが対応する閾値以下である場合に室内４１の空気質が清浄であると判定する。また、処理部１２は、室外４２に配置された空気質センサ３２が複数の因子について濃度の計測を行う場合において、例えば、１つ以上の因子についての計測値が設定されている閾値を超えた場合に、室外４２の空気質が非清浄であると判定し、全ての因子についての計測値それぞれが対応する閾値以下である場合に室外４２の空気質が清浄であると判定する。 As described above, the air quality sensor 31 disposed in the room 41 monitors the concentration of the particulate matter, the concentration of carbon dioxide, and the concentration of the odor component. The air quality sensor 32 disposed outside the room 42 monitors the concentration of particulate matter. In the processing unit 12, a threshold to be compared with the measurement value of the air quality sensor 31 is determined for each factor of air quality, and a threshold value to be compared with the measurement value of the air quality sensor 32 is defined. The threshold value to be compared with the measurement values of the air quality sensor 31 and the air quality sensor 32 is set such that the air quality is determined to be nonclean when the measurement value of the air quality sensor 31 or the air quality sensor 32 is larger than the threshold value. Be done. In other words, if the measured value is less than or equal to the threshold value, the air quality is determined to be clean. That is, when the measurement value of the air quality sensor 31 disposed in the room 41 exceeds the threshold value, it means that the air in the room 41 needs to be cleaned. When determining whether the air quality is clean or non-clean by comparing the measured value and the threshold value, the measured value determined to be clean as the comparison result is on the clean side with respect to the threshold and is non-clean as the comparison result The measured value to be determined is expressed as being on the non-clean side with respect to the threshold. In the above example, the measured value is on the clean side if it is greater than the threshold and on the non-clean side if it is less than the threshold, but as another example, it is on the clean side if the measured value is greater than the threshold, It is also possible to determine that the level is less than the threshold value so as to be on the non-clean side. In the case where the air quality sensor 31 disposed in the room 41 measures the concentration of a plurality of factors, the processing unit 12 measures the concentration of one or more factors, for example, when the measured value exceeds a set threshold. The air quality of the room 41 is determined to be non-clean, and the air quality of the room 41 is determined to be clean when the measured values for all the factors are equal to or less than the corresponding threshold values. Further, in the case where the air quality sensor 32 disposed outside the room 42 measures the concentration with respect to a plurality of factors, the processing unit 12 has exceeded, for example, the threshold value for which one or more factors have been set. In this case, it is determined that the air quality outside the room 42 is non-clean, and it is determined that the air quality outside the room 42 is clean when the measured values for all factors are equal to or less than the corresponding threshold values.
　図３Ａは、室内４１の空気質と室外４２の空気質との両方が清浄である状態を示している。すなわち、空気質センサ３１の計測値と空気質センサ３２の計測値とがともに閾値以下であるという条件が成立している状態である。この状態では、室外４２から室内４１に外気をそのまま取り込んでも室内４１の空気質が低下することはない。そのため、処理部１２は、換気装置２１を第２の状態（第３種換気）として室内４１の空気を排気させ、また通気装置２２を開いて室外４２と室内４１との間で空気を流通させるように、換気装置２１および通気装置２２に与える指示を定める。そして、制御装置１０は、指示部１３により、処理部１２が定めた指示を、換気装置２１および通気装置２２に伝える。 FIG. 3A shows that both the air quality of the room 41 and the air quality of the room 42 are clean. That is, the condition that the measurement value of the air quality sensor 31 and the measurement value of the air quality sensor 32 are both equal to or less than the threshold value is satisfied. In this state, even if the outside air is taken from the outside room 42 into the room 41 as it is, the air quality of the room 41 does not deteriorate. Therefore, the processing unit 12 exhausts the air in the room 41 with the ventilator 21 in the second state (type 3 ventilation), and opens the ventilation device 22 to circulate the air between the outdoor 42 and the room 41. As such, the instructions given to the ventilator 21 and the ventilator 22 are determined. Then, the control device 10 causes the instruction unit 13 to transmit the instruction determined by the processing unit 12 to the ventilation device 21 and the ventilation device 22.
　したがって、図３Ａに示すように、換気装置２１による機械換気によって室内４１の空気が室外４２に排気されるように空気流Ｘ１が形成され、同時に、室外４２の空気が通気装置２２を通して室内４１に取り込まれる空気流Ｙ１が形成される。図３Ａではレンジフード２３は動作しておらず、換気装置２１の排気用のファン２１４のみの機械換気が行われる。 Therefore, as shown in FIG. 3A, the air flow X1 is formed so that the air in the room 41 is exhausted to the outside 42 by mechanical ventilation by the ventilation device 21 and at the same time the air in the outside 42 passes through the ventilation device 22 to the room 41. An air flow Y1 to be taken in is formed. In FIG. 3A, the range hood 23 is not operating, and mechanical ventilation of only the fan 214 for exhausting the ventilation device 21 is performed.
　ところで、換気装置２１と通気装置２２との位置関係にもよるが、図３Ａのような配置の場合、通気装置２２を通して室外４２から取り込まれた空気は、換気装置２１と通気装置２２との近辺にとどまり、室内４１の大部分の範囲には十分に拡散しない可能性がある。そのため、図３Ａに示す配置例では、室内４１において通気装置２２の反対側に空気清浄機２４が配置されている。ここでは、空気清浄機２４は、空気質の改善を行うのではなく、室内４１を循環する空気流Ｚ１を形成するために用いられる。処理部１２は、空気清浄機２４に空気を循環させるように、空気清浄機２４に与える指示を定める。そして、制御装置１０は、指示部１３により、処理部１２が定めた指示を、空気清浄機２４に伝える。 By the way, although it depends on the positional relationship between the ventilating device 21 and the ventilating device 22, in the case of the arrangement as shown in FIG. 3A, the air taken in from the outdoor 42 through the ventilating device 22 is near the ventilating device 21 and the ventilating device 22. There is a possibility that it does not spread sufficiently in most areas of the room 41. Therefore, in the arrangement example shown to FIG. 3A, the air cleaner 24 is arrange | positioned in the chamber | room 41 on the opposite side of the ventilation apparatus 22. As shown in FIG. Here, the air purifier 24 is used to form an air flow Z1 circulating in the room 41 rather than to improve the air quality. The processing unit 12 determines an instruction to be given to the air purifier 24 so that the air purifier 24 circulates the air. Then, the control device 10 causes the instruction unit 13 to transmit the instruction determined by the processing unit 12 to the air purifier 24.
　室内４１と室外４２との空気質が清浄である場合には、上述の動作になるように、換気装置２１と通気装置２２と空気清浄機２４とに、制御装置１０が指示を与える。 When the air quality in the room 41 and the room 42 is clean, the control device 10 gives an instruction to the ventilation device 21, the ventilation device 22, and the air cleaner 24 so that the above-described operation is performed.
　ここで、室内４１と室外４２との両方において空気質が清浄である状態（図３Ａ）に対して、室内４１の空気質が非清浄になったとする。すなわち、制御装置１０において、取得部１１が室内４１の空気質センサ３１から取得した計測値が所定の閾値に対して非清浄側になったとする。この状態では、室外４２の空気質は清浄であるから通気装置２２を通して室外４２の空気を室内４１に取り込むことが可能である。このような状態では、室内４１の空気と室外４２の空気とを迅速に入れ替えることが望ましい。そこで、図３Ｂのように、制御装置１０は、図３Ａの状態に加えて、レンジフード２３が運転するように指示を与える。 Here, it is assumed that the air quality of the room 41 is non-clean with respect to the state (FIG. 3A) in which the air quality is clean in both the room 41 and the outdoor room 42. That is, in the control device 10, it is assumed that the measurement value acquired by the acquisition unit 11 from the air quality sensor 31 in the room 41 is on the non-clean side with respect to the predetermined threshold. In this state, the air quality outside the room 42 is clean, so that the air outside the room 42 can be taken into the room 41 through the ventilation device 22. In such a state, it is desirable that the air inside the room 41 and the air outside the room 42 be quickly replaced. Therefore, as shown in FIG. 3B, in addition to the state of FIG. 3A, the control device 10 instructs the range hood 23 to operate.
　レンジフード２３が運転を開始すると、レンジフード２３を通して室内４１から室外４２に排気されるように空気流Ｘ２が新たに形成されるから、換気装置２１とレンジフード２３とにより、室内４１から単位時間当たりに排気される空気量が増加する。その結果、通気装置２２を通して単位時間当たりに室外４２から室内４１に導入される空気量も増加する。すなわち、室内４１の空気が迅速に換気されることになる。 When the range hood 23 starts operation, an airflow X2 is newly formed so as to be exhausted from the room 41 to the outside room 42 through the range hood 23. Thus, the ventilation device 21 and the range hood 23 make the unit time from the room 41 The amount of air exhausted per hit increases. As a result, the amount of air introduced from the outside room 42 to the room 41 per unit time through the ventilation device 22 also increases. That is, the air in the room 41 is ventilated quickly.
　一方、図３Ａの状態から室外４２の空気質が非清浄になったとすると、室外４２の空気を室内４１にそのまま取り込むと、室内４１の空気質が低下することになる。そのため、制御装置１０は、図３Ｃのように、通気装置２２の開閉装置２２２を閉じるように指示を与え、空気流Ｙ１を停止させる。この状態では、制御装置１０は、換気装置２１における吸気用のファン２１３の運転を開始させる。言い換えると、制御装置１０は、換気装置２１が第１の状態で運転するように指示を与える。ファン２１３の運転中には、フィルタ２１５を通して室外４２から室内４１への空気流Ｙ２が形成される。つまり、非清浄である室外４２の空気が、フィルタ２１５を通して清浄化された後に室内４１に取り込まれる。したがって、室内４１の空気質を低下させることなく、室外４２から室内４１に空気を取り込むことが可能になる。 On the other hand, assuming that the air quality of the outdoor room 42 becomes non-clean from the state of FIG. 3A, if the air of the outdoor room 42 is taken into the room 41 as it is, the air quality of the indoor room 41 decreases. Therefore, as shown in FIG. 3C, the control device 10 instructs the closing device 222 of the ventilation device 22 to close, and stops the air flow Y1. In this state, the control device 10 starts the operation of the suction fan 213 in the ventilation device 21. In other words, the controller 10 instructs the ventilator 21 to operate in the first state. During operation of the fan 213, an air flow Y2 from the outside room 42 to the room 41 through the filter 215 is formed. That is, non-cleaned air outside the room 42 is taken into the room 41 after being cleaned through the filter 215. Therefore, air can be taken from the outside room 42 into the room 41 without reducing the air quality of the room 41.
　図３Ｂの状態と図３Ｃの状態とは、室内４１と室外４２との一方だけの空気質が非清浄である状態を示している。これに対して、室内４１と室外４２との両方の空気質が非清浄になると、制御装置１０は、図３Ｄのように、換気装置２１における吸気用のファン２１３と排気用のファン２１４とを同時に運転し、通気装置２２の開閉装置２２２を閉じ、レンジフード２３を運転させる。 The state of FIG. 3B and the state of FIG. 3C show a state in which the air quality of only one of the indoor 41 and the outdoor 42 is non-clean. On the other hand, when the air quality of both the room 41 and the room 42 is not clean, the control device 10, as shown in FIG. 3D, removes the intake fan 213 and the exhaust fan 214 in the ventilation device 21. At the same time, the opening / closing device 222 of the ventilating device 22 is closed and the range hood 23 is operated.
　すなわち、図３Ｄの状態は、図３Ｂの状態に対して室外４２の空気質が低下しているから、室外４２の空気が通気装置２２を通して室内４１に導入されないように開閉装置２２２を閉じている。室外４２の空気は、フィルタ２１５を通って清浄化された後に室内４１に導入される。したがって、室内４１の空気質の低下が防止される。 That is, in the state of FIG. 3D, since the air quality of the outdoor 42 is lower than the state of FIG. 3B, the opening / closing device 222 is closed so that the air of the outdoor 42 is not introduced into the room 41 through the ventilation device 22. . The air outside the room 42 is introduced into the room 41 after being cleaned through the filter 215. Therefore, the deterioration of the air quality in the room 41 is prevented.
　加えて、図３Ｄの状態は、図３Ｃの状態に対して、室内４１の空気質が低下しているから、室内４１の空気が室外４２に迅速に排気されるように、レンジフード２３を換気装置２１と併せて運転している。つまり、換気装置２１の吸気用のファン２１３に加えてレンジフード２３を運転しているから、単位時間当たりに室内４１から室外４２に排気される空気量が増加し、空気質が低下した室内４１の空気を迅速に室外４２に排気することができる。そして、換気装置２１における吸気用のファン２１３が運転されていることにより、室外４２から清浄化された空気が室内４１に取り込まれ、室内４１の空気質が迅速に改善されることになる。なお、図３Ａ～図３Ｄに示す例において、換気装置２１における排気用のファン２１４および空気清浄機２４は省略可能である。 In addition, in the state of FIG. 3D, since the air quality of the room 41 is lower than the state of FIG. 3C, the range hood 23 is ventilated so that the air of the room 41 is exhausted to the outside room 42 quickly. It is operating in conjunction with the device 21. That is, since the range hood 23 is operated in addition to the suction fan 213 of the ventilating apparatus 21, the amount of air exhausted from the room 41 to the outside 42 per unit time increases and the air quality decreases. Air can be exhausted to the outside room 42 quickly. Then, since the intake fan 213 in the ventilating apparatus 21 is operated, the air cleaned from the outside room 42 is taken into the room 41, and the air quality of the room 41 is rapidly improved. In the example shown in FIGS. 3A to 3D, the exhaust fan 214 and the air cleaner 24 in the ventilator 21 can be omitted.
　上述した動作によって、室外４２の空気質が清浄であれば、フィルタ２１５を通すことなく室外４２から室内４１に空気を取り入れられる。そのため、フィルタ２１５の汚れが抑制される。また、制御装置１０は、換気装置２１によって室内４１の空気を室外４２に排気する際に、レンジフード２３を併用する動作を可能にしている。したがって、換気装置２１が小型であっても、部屋４０の全体では単位時間当たりに排気される空気量を大きくし、室内４１の空気を迅速に換気することが可能になる。 If the air quality of the outdoor 42 is clean by the above-described operation, air can be taken into the indoor 41 from the outdoor 42 without passing through the filter 215. Therefore, the contamination of the filter 215 is suppressed. Further, when the air in the room 41 is exhausted to the outside 42 by the ventilation device 21, the control device 10 enables an operation of using the range hood 23 in combination. Therefore, even if the ventilating device 21 is small, the amount of air exhausted per unit time in the entire room 40 can be increased, and the air in the room 41 can be ventilated quickly.
　なお、上述した制御装置１０は、コンピュータを主なハードウェア構成として備えることとしたが、プログラム（ソフトウェア）を用いないで個別部品、半導体集積回路等によって構成してもよい。なお、制御装置１０は、通信Ｉ／Ｆとして換気装置２１、通気装置２２、レンジフード２３、空気清浄機２４、空気質センサ３１、３２、温湿度センサ３３等を有線接続する物理的なインタフェースを有し得る。コンピュータは、例えば、メモリをプロセッサと一体に備えるマイコン（Microcontroller）、メモリが別に設けられるＭＰＵ（Micro Processing Unit）等から適宜に選択される。 Although the control device 10 described above includes the computer as the main hardware configuration, it may be configured by an individual component, a semiconductor integrated circuit, or the like without using a program (software). In addition, the control device 10 has a physical interface connecting the ventilation device 21, the ventilation device 22, the range hood 23, the air cleaner 24, the air quality sensors 31, 32, the temperature and humidity sensor 33 and the like as communication I / F. It can have. The computer is appropriately selected from, for example, a microcomputer (Microcontroller) integrally including a memory with a processor, an MPU (Micro Processing Unit) or the like separately provided with a memory.
　プログラムは、ＲＯＭに書き込まれた状態で提供されるほか、インターネットのような電気通信回線を通して提供されてもよい。また、プログラムは、コンピュータで読み取り可能な記録媒体を用いて提供されてもよい。このプログラムは、コンピュータを制御装置１０として機能させるものである。室内４１の空気質を計測する空気質センサ３１、室外４２の空気質を計測する空気質センサ３２および換気装置２１と通信可能なコンピュータを制御装置１０として機能させるためのプログラムは、例えば次のステップ（手順）を含む制御処理を実行させるためのコンピュータプログラムである。すなわち、制御処理は、室外４２の空気質を計測する空気質センサ３２から計測値を取得する取得ステップと、空気質センサ３２が計測した計測値（取得ステップで取得された計測値）が所定の閾値に対して非清浄側である場合には、空気質を改善するフィルタを通して室外４２から室内４１に吸気すると同時に室内４１から室外４２への排気を行う第１の状態で換気装置２１を運転させ、空気質センサ３２が計測したその計測値がその所定の閾値に対して清浄側である場合には、室内４１から室外４２への排気を行う第２の状態で換気装置２１を運転させるように換気装置２１に指示を伝える指示ステップとを含む。ここで、制御処理における指示ステップでは、室内４１と室外４２との間で空気の流通を許可する状態と空気の流通を遮断する状態とが選択可能な通気装置２２が配置されている場合に、換気装置２１を第１の状態で運転する期間に、空気の流通を遮断するように通気装置２２に指示を伝え、換気装置２１を第２の状態で運転している期間に、空気の流通を許可するように通気装置２２に指示を伝えてもよい。また、更に、取得ステップにおいて室内４１の空気質を計測する空気質センサ３１から計測値を取得し、指示ステップでは、室内４１から室外４２へ排気を行う排気用換気扇（レンジフード２３）が部屋４０に配置されている場合に、空気質センサ３１が計測した計測値（取得ステップで取得された計測値）が所定の閾値に対して非清浄側である期間に、排気用換気扇を換気装置２１と併せて運転するように排気用換気扇に指示を伝えてもよい。 The program may be provided as written in a ROM or may be provided through a telecommunication line such as the Internet. Also, the program may be provided using a computer readable recording medium. This program causes a computer to function as the control device 10. A program for causing a computer that can communicate with the air quality sensor 31 that measures the air quality of the room 41, the air quality sensor 32 that measures the air quality of the outdoor room 42, and the ventilator 21 to function as the control device 10 is, for example, the following steps A computer program for executing control processing including (procedure). That is, in the control process, an acquisition step of acquiring a measurement value from the air quality sensor 32 which measures the air quality of the outdoor 42, and a measurement value (measurement value acquired in the acquisition step) measured by the air quality sensor 32 are predetermined. In the case of the non-clean side with respect to the threshold value, the ventilation device 21 is operated in a first state in which air is taken into the room 41 from the outdoor 42 through the filter for improving air quality and exhausting from the room 41 to the outdoor 42 simultaneously. If the measured value measured by the air quality sensor 32 is on the clean side with respect to the predetermined threshold value, the ventilation device 21 is operated in the second state in which the exhaust from the indoor 41 to the outdoor 42 is performed. And an instruction step of transmitting an instruction to the ventilator. Here, in the instruction step in the control process, in the case where the ventilating device 22 capable of selecting the state of permitting the flow of air between the indoor 41 and the outdoor 42 and the state of blocking the flow of air is arranged. In a period in which the ventilation device 21 is operated in the first state, an instruction is sent to the ventilation device 22 so as to block the flow of air, and in the period in which the ventilation device 21 is operated in the second state An indication may be sent to the venting device 22 to allow. Furthermore, in the acquisition step, the measurement value is acquired from the air quality sensor 31 that measures the air quality of the room 41, and in the instruction step, the exhaust ventilation fan (range hood 23) for exhausting from the room 41 to the room 42 is the room 40 If the measurement value measured by the air quality sensor 31 (the measurement value acquired in the acquisition step) is not clean with respect to the predetermined threshold value, the exhaust ventilation fan is An instruction may be given to the exhaust ventilation fan so as to drive together.
　以上説明した本実施形態の制御装置１０は、取得部１１と処理部１２と指示部１３とを備える。取得部１１は、室内４１の空気質を計測する（第１の）空気質センサ３１および室外４２の空気質を計測する（第２の）空気質センサ３２から計測値を取得する。指示部１３は、空気質を改善するフィルタを通して室外４２から室内４１に吸気すると同時に室内４１から室外４２への排気を行う第１の状態と、室内４１から室外４２への排気を行う第２の状態とを選択するように換気装置２１に動作の指示を行う。処理部１２は、取得部１１が取得した計測値に基づいて指示部１３に与える指示の内容を定める。処理部１２は、（第２の）空気質センサ３２が計測した計測値が所定の閾値に対して非清浄側である場合には、第１の状態で換気装置２１を運転させる。一方、処理部１２は、（第２の）空気質センサ３２が計測した空気質が閾値に対して清浄側である場合には、第２の状態で換気装置２１を運転させるように指示の内容を定める。 The control device 10 of the present embodiment described above includes the acquisition unit 11, the processing unit 12, and the instruction unit 13. The acquisition unit 11 acquires measurement values from the (first) air quality sensor 31 that measures the air quality of the room 41 and the (second) air quality sensor 32 that measures the air quality of the outdoor room 42. The instruction unit 13 takes a first state in which air is exhausted from the room 41 to the room 42 at the same time as drawing air from the room 42 to the room 41 through a filter for improving air quality and a second state for discharging the room 41 to the room 42. The operation instruction is given to the ventilator 21 to select the state. The processing unit 12 determines the content of the instruction given to the instruction unit 13 based on the measurement value acquired by the acquisition unit 11. The processing unit 12 operates the ventilation device 21 in the first state when the measurement value measured by the (second) air quality sensor 32 is non-clean side with respect to the predetermined threshold. On the other hand, when the air quality measured by the (second) air quality sensor 32 is on the clean side with respect to the threshold, the processing unit 12 instructs the ventilator 21 to operate in the second state. Determine
　この構成によれば、室外４２の空気質が閾値に対して非清浄側である場合に、排気に加えてフィルタ２１５を通しての吸気を行う第１の状態が選択される。また、室外４２の空気質が閾値に対して清浄側である場合に、排気のみを行う第２の状態が選択される。そのため、室外４２の空気が清浄であればフィルタ２１５を通さずに換気が行われ、フィルタ２１５の汚れが抑制される。一方、室外４２の空気質が低下すれば、フィルタ２１５を通して室内４１に空気を取り込むことにより、室内４１の空気質の低下が防止される。 According to this configuration, in the case where the air quality outside the room 42 is on the non-clean side with respect to the threshold value, the first state in which the intake through the filter 215 is performed in addition to the exhaust is selected. In addition, when the air quality outside the room 42 is on the clean side with respect to the threshold, the second state in which only the exhaust is performed is selected. Therefore, if the air outside the room 42 is clean, ventilation is performed without passing through the filter 215, and contamination of the filter 215 is suppressed. On the other hand, if the air quality of the outdoor room 42 is lowered, the air is taken into the room 41 through the filter 215, whereby the air quality of the room 41 is prevented from being lowered.
　換気装置２１は、吸気用のファン２１３と排気用のファン２１４とをハウジング２１０に備え、ハウジング２１０は吸気用のファン２１３に対応する流路２１１内にフィルタ２１５を備えることとしてもよい。処理部１２は、第１の状態では吸気用のファン２１３と排気用のファン２１４とが同時に運転し、第２の状態では排気用のファン２１３のみが運転するように指示の内容を定める。 The ventilation device 21 may include a suction fan 213 and a suction fan 214 in the housing 210, and the housing 210 may include a filter 215 in the flow path 211 corresponding to the suction fan 213. In the first state, the processing unit 12 determines the content of the instruction so that the intake fan 213 and the exhaust fan 214 operate at the same time, and in the second state, only the exhaust fan 213 operates.
　この構成によれば、１台の換気装置２１を用いて第１の状態と第２の状態とが選択可能になる。 According to this configuration, it is possible to select the first state and the second state using one ventilator 21.
　ここで、室内４１と室外４２との間で空気の流通を許可する状態と空気の流通を遮断する状態とが選択可能な通気装置２２が配置されている場合を想定する。この場合、処理部１２は、換気装置２１を第１の状態で運転する期間に、通気装置２２による空気の流通を遮断するように指示の内容を定めてもよい。また、処理部１２は、換気装置２１を第２の状態で運転している期間に、通気装置２２による空気の流通を許可するように指示の内容を定めてもよい。 Here, it is assumed that the ventilating device 22 is disposed, which can select the state of permitting the flow of air between the indoor 41 and the outdoor 42 and the state of blocking the flow of air. In this case, the processing unit 12 may determine the content of the instruction to shut off the flow of air by the ventilation device 22 during the operation of the ventilation device 21 in the first state. In addition, the processing unit 12 may define the content of the instruction to allow the air circulation by the ventilation device 22 while the ventilation device 21 is operated in the second state.
　この構成によれば、室外４２の空気質が低下し、室外４２の空気が換気装置２１によりフィルタ２１５を通して室内４１に取り込まれている期間には、通気装置２２による空気の流通が遮断され、室内４１に室外４２の空気が直接取り込まれることがない。その一方で、室外４２の空気質が清浄である期間には、通気装置２２を通して室内４１に室外４２の空気が直接取り込まれるから、自然な通風に近い状態を実現できる。 According to this configuration, during the period when the air quality of the outdoor 42 is reduced and the air of the outdoor 42 is taken into the room 41 through the filter 215 by the ventilation device 21, the flow of air by the ventilation device 22 is blocked. The air outside the room 42 is not directly taken into the room 41. On the other hand, since the air outside the room 42 is directly taken into the room 41 through the ventilation device 22 during the period when the air quality of the room 42 is clean, a state close to natural ventilation can be realized.
　また、室内４１から室外４２へ排気を行う排気用換気扇（レンジフード２３）が部屋４０に配置されている場合を想定する。この場合、処理部１２は、（第１の）空気質センサ３１が計測した計測値が所定の閾値に対して非清浄側である期間に、排気用換気扇（レンジフード２３）を換気装置２１と併せて運転するように指示の内容を定めてもよい。 Further, it is assumed that the exhaust ventilation fan (range hood 23) for exhausting air from the inside 41 to the outside 42 is disposed in the room 40. In this case, the processing unit 12 operates the exhaust ventilation fan (range hood 23) and the ventilator 21 in a period in which the measured value measured by the (first) air quality sensor 31 is on the non-clean side with respect to the predetermined threshold. The content of the instruction may be determined to drive together.
　この構成によれば、換気装置２１だけでは室内４１から室外４２へ空気を排出する能力が低い場合でも、排気用換気扇（レンジフード２３）との併用によって、室内４１の空気を室外４２に迅速に排気することが可能になる。 According to this configuration, even when the ventilating device 21 alone has a low ability to discharge air from the room 41 to the outside room 42, the air in the room 41 can be quickly taken to the outside room 42 by using in combination with the exhaust fan (range hood 23). It becomes possible to exhaust.
　上述した通風制御システム１は、制御装置１０と換気装置２１とを備える。換気装置２１は、空気質を改善するフィルタ２１５を通して室外４２から室内４１に吸気すると同時に室内４１から室外４２への排気を行う第１の状態と、室内４１から室外４２への排気を行う第２の状態とが選択可能である。 The above-described ventilation control system 1 includes a control device 10 and a ventilation device 21. The ventilation device 21 sucks air from the outdoor 42 to the room 41 through the filter 215 for improving air quality and at the same time exhausts the air from the room 41 to the outdoor 42 and performs exhausting the air from the room 41 to the outdoor 42. And can be selected.
