　本発明は、新気システムの技術分野に関し、特に新気システムの制御方法に関する。 The present invention relates to the technical field of fresh air systems, and more particularly to a control method for fresh air systems.
　空気調和機に用いられる内気循環方式に比べて、新気システムの動作方式は、より健康に有益な置換式であり、屋外の新鮮な空気を室内に吸入し、室内に入った空気を濾過して除塵することができると同時に、室内の排気ガスを室外に排出し、空気流通を維持したまま室内を快適に保つことができる。 Compared to the inside air circulation method used in air conditioners, the operation method of the fresh air system is a replacement method that is more beneficial to health, sucking fresh outdoor air into the room and filtering the indoor air At the same time, exhaust gas from the room can be discharged to the outside, and the room can be kept comfortable while air circulation is maintained.

As can be seen from feedback on the usage of conventional fresh air systems, the majority of users are less likely to use fresh air systems on a daily basis due to the high energy consumption and high operating costs of fresh air systems. Ventilation using conventional methods such as opening doors and windows is preferred.

　新気システムは、制御ユニット、送風ユニット及び複数の検出ユニットを含む。ここに、送風ユニットは、モータとファンとを含む。制御ユニットは、モータに電気的に接続され、モータの動力出力部は、ファンの動力受信部に機械的に接続され、制御ユニットは、モータに駆動信号を出力し、モータを動作させるように駆動し、さらにファンを動作させるように駆動し、新気を導入させる。 The fresh air system includes a control unit, a blower unit and multiple detection units. Here, the blower unit includes a motor and a fan. The control unit is electrically connected to the motor, the power output of the motor is mechanically connected to the power reception of the fan, and the control unit outputs a drive signal to the motor to drive the motor to operate. Then, the fan is driven to introduce fresh air.

　ここの「検出結果の分析データ」は、検出結果に基づいて計算して分析した複数種のデータを含み、例えば、平均値及び予知値である。 A plurality of types of detection modes are set in the control unit, and the control unit executes one of the detection modes as a detection mode for operation control.
FIG. 1 is a control flowchart of the fresh air system provided by the present invention, and the control method of the fresh air system includes:
S1 in which a plurality of detection units detect indoor air quality and acquire detection results;
When the detection results obtained by the plurality of detection units satisfy the conditions for switching to another detection mode, the control unit switches the detection mode for operation control S2;
S3 for the control unit to compare and judge the detection result or the analysis data of the detection result with the set value, obtain the judgment result, and then adjust the operation of the blower unit according to the judgment result.
The "analysis data of detection results" here includes multiple types of data calculated and analyzed based on the detection results, such as average values and prediction values.
　本発明の制御方法において、複数種の検出モードは、第１の検出モード、第２の検出モード及び第３の検出モードのうちの少なくとも二種を含む。送風ユニットの初期状態は、オフ状態である。 　In the control method of the present invention, the plurality of detection modes includes at least two of a first detection mode, a second detection mode, and a third detection mode. The initial state of the blower unit is the OFF state.
　運転制御用の検出モードが第１の検出モードである場合、ステップＳ３において、制御ユニットは、同種類の検出結果に対して平均値を取り、例えばＣＯ２の濃度の平均値、ホルムアルデヒドの濃度の平均値等のデータを取得し、その後、これらの平均値データを第１の検出モードの設定値と比較する。同種類の検出結果の平均値が第１の検出モードの設定値以上であれば、送風ユニットをオンにする。第１の検出モードは、新気システムの大部分の使用シーンでの省エネ要件を満たすことができ、複数種の検出結果の平均値と設定値との比較結果に基づいて送風ユニットを制御し、検出環境全体での空気質が基準に達することを確保し、快適性を確保しながら使用コストを低減することを目的とする。 If the detection mode for operation control is the first detection mode, in step S3, the control unit averages the detection results of the same kind, for example, the average concentration of CO2 , the concentration of formaldehyde, Data, such as average values, are obtained and then these average data are compared with the set values of the first detection mode. If the average value of the detection results of the same type is equal to or greater than the set value of the first detection mode, the blower unit is turned on. The first detection mode can meet the energy saving requirements in most usage scenes of the fresh air system, and controls the blower unit based on the comparison result between the average value of the detection results of multiple types and the set value, The purpose is to ensure that the air quality in the entire detection environment reaches the standard, and to reduce the cost of use while ensuring comfort.
　運転制御用の検出モードが第２の検出モードである場合、ステップＳ３において、制御ユニットは、いずれか一つの検出ユニットの検出結果を該検出ユニットの設定値と比較する。いずれか一つの検出ユニットの検出結果が該検出ユニットの設定値以上であれば、送風ユニットをオンにする。第２の検出モードでは、制御ユニットは、いずれか一つの検出環境での空気質の変化にタイムリーに対処することができる。第２の検出モードに備えられる可能な応用シーンは、オフィスエリアであり、元にオフィスエリアの各所に分散した作業者が会議室に集中して会議すると、会議室内の二酸化炭素の濃度値が急激に上昇し、会議室内に設けられた検出ユニットの設定値を超え、この時に、送風ユニットがタイムリーに新気を導入すると、会議室内の空気質を大幅に改善し、人の集まりによる蒸れと不快感を回避することができる。 When the detection mode for operation control is the second detection mode, in step S3, the control unit compares the detection result of any one detection unit with the set value of the detection unit. If the detection result of any one detection unit is greater than or equal to the set value of the detection unit, turn on the blower unit. In the second detection mode, the control unit can timely react to changes in air quality in any one detection environment. A possible application scene provided for the second detection mode is an office area. When workers who were originally dispersed in different parts of the office area gather in a conference room for a meeting, the concentration value of carbon dioxide in the conference room suddenly increases. exceeds the set value of the detection unit installed in the conference room, and at this time, the air blower unit introduces fresh air in a timely manner, greatly improving the air quality in the conference room, Discomfort can be avoided.
　運転制御用の検出モードが第３の検出モードである場合、ステップＳ３において、制御ユニットは、指定検出ユニットの検出結果を指定検出ユニットの設定値と比較する。指定検出ユニットの検出結果が指定検出ユニットの設定値以上であれば、送風ユニットをオンにする。第３の検出モードは、ユーザの個性的な使用要求を満たすことができ、制御ユニットがユーザの指定した検出環境での空気質の変化にタイムリーに対処する。第３の検出モードに備えられる可能な応用シーンは、書斎であり、ユーザが長時間書斎にいる必要がある場合、書斎の検出ユニットを指定検出ユニットに設定することができ、書斎内の二酸化炭素の濃度が指定検出ユニットの設定値を超えると、送風ユニットは、タイムリーに新気を導入する。該検出方式は、省エネに寄与するだけでなく、ユーザの使用快適性要件をよく満たすことができる。 When the detection mode for operation control is the third detection mode, in step S3, the control unit compares the detection result of the specified detection unit with the set value of the specified detection unit. If the detection result of the designated detection unit is greater than or equal to the set value of the designated detection unit, the blower unit is turned on. The third detection mode can meet the user's individual usage requirements, and the control unit timely reacts to changes in air quality in the user's designated detection environment. A possible application scene provided for the third detection mode is the study, if the user needs to stay in the study for a long time, the detection unit in the study can be set as the designated detection unit, and the carbon dioxide in the study When the concentration of the air exceeds the set value of the specified detection unit, the blower unit introduces fresh air in a timely manner. The detection scheme not only contributes to energy saving, but also can well meet the user's comfort requirements.
　ステップＳ１において、新気システムの工場出荷時に設定された運転制御用の検出モードは、第１の検出モードであり、ユーザは、自体の要求に合わせて、他の検出モードを運転制御用の検出モードとして設定してもよい。 In step S1, the detection mode for operation control set when the fresh air system is shipped from the factory is the first detection mode, and the user can select other detection modes for operation control according to his/her own requirements. You can set it as a mode.
　ステップＳ２において、突発状況にタイムリーに対応し、ユーザの快適性を確保した上で新気システムの省エネ性を向上させるために、いずれの異なる検出モードの間にも切替条件がある。切替条件を満たすと、制御ユニットが運転制御用の検出モードを切り替えた後でステップＳ３に進み、切替条件を満たさないと、Ｓ１における運転制御用の検出モードを維持したままステップＳ３に進む。 In step S2, there are switching conditions between any of the different detection modes in order to respond to sudden situations in a timely manner, ensure user comfort, and improve the energy efficiency of the fresh air system. If the switching condition is satisfied, the control unit switches the detection mode for operation control, and the process proceeds to step S3. If the switching condition is not satisfied, the process proceeds to step S3 while maintaining the detection mode for operation control in S1.
　ステップＳ３において、上記三種類の検出モードにおいて、ＣＯ２の濃度についての設定値は、７００ｐｐｍであり、ＰＭ２．５についての設定値は、７５ｕｇ／ｍ３であり、ホルムアルデヒド／ＴＶＯＣについての設定値は、０．１ｍｇ／ｍ３であり、温度についての設定値は、２６℃であり、検出結果／平均値が設定値よりも大きい場合、送風ユニットをオンにする。 In step S3, in the above three detection modes, the set value for the concentration of CO2 is 700 ppm, the set value for PM2.5 is 75 ug/ m3 , and the set value for formaldehyde/TVOC is , 0.1 mg/m 3 and the setpoint for the temperature is 26° C. If the detection result/average value is greater than the setpoint, turn on the blower unit.
　それ以外、本発明に検出結果／平均値が設定値よりも小さい場合に送風ユニットをオンにする状況も存在する。例えば、湿度についての設定値が５０％であれば、湿度検出結果／平均値が５０％未満の場合、送風ユニットをオンにする。 Other than that, there are situations in the present invention where the blower unit is turned on when the detection result/average value is smaller than the set value. For example, if the setpoint for humidity is 50%, turn on the blower unit if the humidity detection result/average value is less than 50%.
　図２から分かるように、上記ステップＳ１における運転制御用の検出モードが第１の検出モードである場合、ステップＳ２において、いずれか一つの検出ユニットの検出結果が第１の設定時間帯ｔ１内に急激に上昇すると、運転制御用の検出モードが第１の検出モードから第２の検出モードに切り替わる。同様に、運転制御用の検出モードが第３の検出モードである場合、いずれか一つの検出ユニットの検出結果が第３の設定時間帯ｔ３内に急激に上昇すると、運転制御用の検出モードが第３の検出モードから第２の検出モードに切り替わる。該検出ユニットの検出結果が安定した後で、運転制御用の検出モードが第２の検出モードから第１の／第３の検出モードに再び切り替わる。 As can be seen from FIG. 2, when the detection mode for operation control in step S1 is the first detection mode, in step S2, the detection result of any one detection unit is detected within the first set time period t1. When it rises rapidly, the detection mode for operation control switches from the first detection mode to the second detection mode. Similarly, when the detection mode for operation control is the third detection mode, if the detection result of any one of the detection units suddenly rises within the third set time period t3, the detection mode for operation control is changed to Switch from the third detection mode to the second detection mode. After the detection result of the detection unit is stabilized, the detection mode for operation control is switched again from the second detection mode to the first/third detection mode.
　上記切り替え過程は、本発明の以下の具体的な実施例を参照して理解することができる。
　Ｓ１０、運転制御用の検出モードが第３の検出モードであり、複数の検出ユニットが室内の空気質を検出し、第１の検出ユニットが位置する領域内の人数が短時間内に急激に増加するため、第１の検出ユニットの検出結果は、該領域のＣＯ２の濃度が１０ｍｉｎ内に７００ｐｐｍから１８００ｐｐｍまで上昇したことを示す。 The above switching process can be understood with reference to the following specific examples of the invention.
S10, the detection mode for operation control is the third detection mode, a plurality of detection units detect the indoor air quality, and the number of people in the area where the first detection unit is located increases rapidly within a short period of time. Therefore, the detection result of the first detection unit shows that the concentration of CO2 in the area rose from 700ppm to 1800ppm within 10min.
　Ｓ２０、第１の検出ユニットの検出結果が「１０ｍｉｎ内に１０００ｐｐｍだけ上昇した」という切替条件に合致するため、運転制御用の検出モードが第３の検出モードから第２の検出モードに切り替わる。 In S20, the detection result of the first detection unit satisfies the switching condition of "increased by 1000 ppm within 10 minutes", so the detection mode for operation control is switched from the third detection mode to the second detection mode.
　Ｓ３０、１８００ｐｐｍが第１の検出ユニットの設定値８００ｐｐｍ以上となるため、送風ユニットをオンにし、室内に新気を導入し、ユーザの快適さを確保する。 　Since 1800 ppm in S30 is equal to or higher than the set value of 800 ppm of the first detection unit, the blower unit is turned on to introduce fresh air into the room to ensure user comfort.
　Ｓ４０、制御ユニットが第２の検出モードを２０ｍｉｎだけ運転し続けた後で、第１の検出ユニットは、半時間ごとに空気質を検出し、第１の検出ユニットの検出結果が切替条件に合致するか否かを確認し、合致すれば、運転制御用の検出モードは、第２の検出モードのままに維持され、合致しなければ、運転制御用の検出モードが第２の検出モードから第３の検出モードに切り替わる。 S40, after the control unit continues to run the second detection mode for 20min, the first detection unit detects the air quality every half hour, and the detection result of the first detection unit meets the switching condition If it matches, the detection mode for operation control is maintained as the second detection mode, and if not, the detection mode for operation control is changed from the second detection mode to the first detection mode. 3 detection mode.
　好ましくは、制御システムが第２の検出モードを実行する過程において、新気システムを再起動すると、運転制御用の検出モードは、依然として第３の検出モードであり、制御ユニットは、後続の検出結果に基づいて運転制御用の検出モードを切り替えるか否かを判断する。 Preferably, in the course of the control system performing the second detection mode, when the fresh air system is restarted, the detection mode for operation control is still the third detection mode, and the control unit detects subsequent detection results It is determined whether or not to switch the detection mode for operation control based on.
　上記ステップＳ１における運転制御用の検出モードが第２の検出モードである場合、ステップＳ２において、いずれか一つの検出ユニットの検出結果が第２の設定時間帯ｔ２内に常に該検出ユニットの空気質検出上限値以上であれば、運転制御用の検出モードが第２の検出モードから第１の検出モードに切り替わる。例えば、第２の検出ユニットが２４ｈ内に検出したＣＯ２の濃度は、常に２０００ｐｐｍより大きい場合、すなわち、第２の検出ユニットが断線し、故障や損傷する可能性があり、送風ユニットは、第２の検出モードの動作論理でオンに維持されると、新気システムの使用コストを大幅に上げてしまい、省エネで環境に優しいことに不利である。この時に、運転制御用の検出モードが第２の検出モードから第１の検出モードに切り替わると、故障した検出ユニットによる使用コストを効果的に低減し、新気システムの省エネ性を向上させることができる。第２の検出ユニットの故障が解除された後で、運転制御用の検出モードが第１の検出モードから第２の検出モードに再び切り替わる。好ましくは、制御システムが第１の検出モードを実行する過程において、新気システムを再起動すると、運転制御用の検出モードは、依然として第２の検出モードであり、制御ユニットは、後続の検出結果に基づいて運転制御用の検出モードを切り替えるか否かを判断する。 When the detection mode for operation control in step S1 is the second detection mode, in step S2, the detection result of any one of the detection units always indicates the air quality of the detection unit within the second set time period t2. If it is equal to or higher than the detection upper limit value, the detection mode for operation control is switched from the second detection mode to the first detection mode. For example, if the concentration of CO2 detected by the second detection unit within 24h is always greater than 2000ppm, that is, the second detection unit may be disconnected, malfunctioned or damaged, and the blower unit may If kept on with the operating logic of detection mode 2, it would greatly increase the cost of using the fresh air system, which is disadvantageous for energy saving and environmental friendliness. At this time, when the detection mode for operation control is switched from the second detection mode to the first detection mode, it is possible to effectively reduce the usage cost of the failed detection unit and improve the energy saving performance of the fresh air system. can. After the failure of the second detection unit is cleared, the detection mode for operation control switches from the first detection mode to the second detection mode again. Preferably, in the course of the control system performing the first detection mode, when the fresh air system is restarted, the detection mode for operational control is still the second detection mode, and the control unit detects subsequent detection results It is determined whether or not to switch the detection mode for operation control based on.
　上記ステップＳ１における運転制御用の検出モードが第３の検出モードである場合、ステップＳ２において、指定検出ユニットの検出結果が第４の設定時間帯ｔ４内に常に指定検出ユニットの空気質検出上限値以上となるか、又は常に指定検出ユニットの空気質検出下限値以下となれば、運転制御用の検出モードが第３の検出モードから第１の検出モードに切り替わる。例えば、指定検出ユニットが２４ｈ内に検出したＣＯ２の濃度が常に２０００ｐｐｍ以上となるか、又は常に４００ｐｐｍ以下となれば、指定検出ユニットが断線し、故障や損傷する可能性があり、送風ユニットが第３の検出モードの動作論理でオン又はオフを維持し、制御ユニットがユーザが指定した検出位置での空気質の変化にタイムリーに対処することができず、それにより、ユーザの使用コスト又は快適性を損なってしまう。この時に運転制御用の検出モードが第３の検出モードから第１の検出モードに切り替わると、故障した検出ユニットによる使用コストを効果的に減少させ、新気システムの省エネ性を向上させることができるほか、二番目によいこととして、制御ユニットによる検出環境全体での空気質に対する把握や制御を確保し、ユーザの基本的な快適さを保障する。指定検出ユニットの故障が解除された後で、運転制御用の検出モードが第１の検出モードから第３の検出モードに再び切り替わる。好ましくは、制御システムが第１の検出モードを実行する過程において、新気システムを再起動すると、運転制御用の検出モードは、依然として第３の検出モードであり、制御ユニットは、後続の検出結果に基づいて運転制御用の検出モードを切り替えるか否かを判断する。 When the detection mode for operation control in step S1 is the third detection mode, in step S2, the detection result of the designated detection unit always reaches the air quality detection upper limit value of the designated detection unit within the fourth set time period t4. When the air quality is equal to or higher than or equal to or lower than the air quality detection lower limit of the designated detection unit, the detection mode for operation control is switched from the third detection mode to the first detection mode. For example, if the concentration of CO 2 detected by the designated detection unit within 24 hours is always 2000ppm or more or always 400ppm or less, the designated detection unit may be disconnected, fail or be damaged, and the blower unit may The operating logic of the third detection mode remains on or off, and the control unit is unable to timely respond to changes in air quality at user-specified detection locations, thereby increasing user usage costs or You lose comfort. At this time, if the detection mode for operation control is switched from the third detection mode to the first detection mode, it is possible to effectively reduce the usage cost of the failed detection unit and improve the energy saving of the fresh air system. In addition, the second best thing is to ensure that the control unit can grasp and control the air quality in the whole detection environment, and to ensure the user's basic comfort. After the failure of the designated detection unit is cleared, the detection mode for operation control is switched again from the first detection mode to the third detection mode. Preferably, in the course of the control system performing the first detection mode, when the fresh air system is restarted, the detection mode for operation control is still the third detection mode, and the control unit detects subsequent detection results It is determined whether or not to switch the detection mode for operation control based on.
　図１に示すように、本発明の制御方法は、複数の検出ユニットが第５の設定時間帯ｔ５だけ運転し続けた後で、制御ユニットは、複数の検出ユニットが第５の設定時間帯ｔ５内に取得した複数の検出結果に基づいて、複数の検出ユニットが第６の設定時間帯ｔ６だけ運転し続けた後に取得可能な検出結果を予測し、複数の検出結果の予知値を取得するとともに、検出結果の予知値が検出結果よりも大きいか否かを判断する、ステップＳ２とＳ３との間に設定されたＳ２００をさらに含む。 As shown in FIG. 1, in the control method of the present invention, after the plurality of detection units continue to operate for the fifth set time period t5, the control unit controls the plurality of detection units to operate for the fifth set time period t5. predicting detection results that can be obtained after the plurality of detection units continue to operate for the sixth set time period t6 based on the plurality of detection results obtained in the above, and obtaining prediction values of the plurality of detection results; , S200 set between steps S2 and S3 for determining whether the predicted value of the detection result is greater than the detection result.
　検出結果の予知値が検出結果よりも大きい場合、ステップＳ３において、制御ユニットは、検出結果の予知値／検出結果の予知値の平均値と設定値との比較結果に基づいて、送風ユニットの動作を調節し、検出結果の予知値が検出結果以下である場合、ステップＳ３において、制御ユニットは、検出結果／検出結果の平均値と設定値との比較結果に基づいて、送風ユニットの動作を調節する。以上は、「検出結果の予知値が検出結果以下である」状況を説明したため、ここで詳しい説明を省略する。以下では、「検出結果の予知値が検出結果よりも大きい」場合についてのみ分析する。 If the predicted value of the detection result is greater than the detection result, in step S3, the control unit operates the blower unit based on the result of comparison between the predicted value of the detection result/the average value of the predicted values of the detection result and the set value. and if the predicted value of the detection result is less than or equal to the detection result, in step S3, the control unit adjusts the operation of the blower unit based on the comparison result between the detection result/the average value of the detection results and the set value do. Since the above describes the situation in which "the predicted value of the detection result is equal to or less than the detection result", a detailed description is omitted here. In the following, only the case where "the predicted value of the detection result is greater than the detection result" will be analyzed.
　上記ステップＳ２で確認された運転制御用の検出モードが第１の検出モードである場合、同種類の検出結果の予知値の平均値≧第１の検出モードの設定値＞同種類の検出結果の平均値を満たすと、送風ユニットをオンにし、
　上記ステップＳ２で確認された運転制御用の検出モードが第２の検出モードである場合、いずれか一つの検出ユニットの検出結果の予知値≧該検出ユニットの設定値＞該検出ユニットの検出結果を満たすと、送風ユニットをオンにし、
　上記ステップＳ２で確認された運転制御用の検出モードが第３の検出モードである場合、指定検出ユニットの検出結果の予知値≧指定検出ユニットの設定値＞指定検出ユニットの検出結果を満たすと、送風ユニットをオンにする。 When the detection mode for operation control confirmed in step S2 is the first detection mode, the average value of the predicted values of the same type of detection results≧the set value of the first detection mode>the number of the same type of detection results When the average value is met, turn on the blower unit,
If the detection mode for operation control confirmed in step S2 is the second detection mode, the predicted value of the detection result of any one of the detection units≧the set value of the detection unit>the detection result of the detection unit When satisfied, turn on the blower unit,
When the detection mode for operation control confirmed in step S2 is the third detection mode, if the predicted value of the detection result of the designated detection unit≧the set value of the designated detection unit>the detection result of the designated detection unit is satisfied, Turn on the blower unit.
　一つの応用実施例として、１５人が一つの面積が１００ｍ２である部屋に入り、現在の部屋内のＣＯ２の濃度が６００ｐｐｍであると検出ユニットに検出されるとともに、１５ｍｉｎ後の部屋内のＣＯ２の濃度が１０００ｐｐｍであると予測され、１０００ｐｐｍ≧７００ｐｐｍ＞６００ｐｐｍであるため、送風ユニットをオンにする。ステップＳ２００を経過しないと、制御ユニットは、現在の部屋内のＣＯ２の濃度が７００ｐｐｍよりも大きくなると検出ユニットに検出されてはじめて、送風ユニットをオンにする必要があるため、該設定で、制御ユニットは、検出結果の予知値に基づいて送風ユニットを予めオンにし、空気質が第６の設定時間帯ｔ６に持続的に低下することを回避し、ユーザの使用体験をさらに向上させることができる。 As an application example, 15 people enter a room with an area of 100m2 , the current concentration of CO2 in the room is detected by the detection unit as 600ppm, and the concentration in the room after 15min is The concentration of CO 2 is expected to be 1000ppm, 1000ppm≧700ppm>600ppm, so the blower unit is turned on. Without step S200, the control unit needs to turn on the blower unit only after the detection unit detects that the current concentration of CO 2 in the room is greater than 700 ppm. The unit can pre-turn on the blower unit according to the prediction value of the detection result to avoid the air quality continuously declining in the sixth set time period t6, and further improve the user experience. .
　送風ユニットをオンにした後で、上記ステップＳ２で確認された運転制御用の検出モードが第１の検出モードである場合、同種類の検出結果の予知値の平均値＞同種類の検出結果の平均値≧第１の検出モードの設定値を満たすと、制御ユニットは、送風ユニットの新気導入量を調節する、
　上記ステップＳ２で確認された運転制御用の検出モードが第２の検出モードである場合、いずれか一つの検出ユニットの検出結果の予知値＞該検出ユニットの検出結果≧該検出ユニットの設定値を満たすと、制御ユニットは、送風ユニットの新気導入量を調節する、
　上記ステップＳ２で確認された運転制御用の検出モードが第３の検出モードである場合、指定検出ユニットの検出結果の予知値＞指定検出ユニットの検出結果≧指定検出ユニットの設定値を満たすと、制御ユニットは、送風ユニットの新気導入量を調節する。 After the blower unit is turned on, if the detection mode for operation control confirmed in step S2 is the first detection mode, the average value of the predicted values of the same type of detection results > the same type of detection results When the average value≧the set value of the first detection mode is satisfied, the control unit adjusts the fresh air introduction amount of the blower unit.
If the detection mode for operation control confirmed in step S2 is the second detection mode, the predicted value of the detection result of any one of the detection units>the detection result of the detection unit≧the set value of the detection unit When filled, the control unit adjusts the fresh air intake of the blower unit;
When the detection mode for operation control confirmed in step S2 is the third detection mode, if the predicted value of the detection result of the specified detection unit>the detection result of the specified detection unit≧the set value of the specified detection unit is satisfied, The control unit adjusts the amount of fresh air introduced by the blower unit.
　該設定で、制御ユニットは、検出結果の予知値に基づいて送風ユニットの新気導入量を予め調節することができる。条件を満たす検出結果がＣＯ２の濃度、ホルムアルデヒドの濃度又は微小粒子状物質の濃度等であれば、新気導入量を増大させることができ、空気質が第６の設定時間帯ｔ６に持続的に低下することを回避し、さらにユーザの使用体験を向上させることができ、条件を満たす検出結果が湿度であれば、新気導入量を減少させ、室内の湿度の上昇速度が速すぎることによって、ユーザの不快感を引き起こすことを回避することができる。 With this setting, the control unit can pre-adjust the fresh air introduction amount of the blower unit based on the predicted value of the detection result. If the detection result that satisfies the conditions is the concentration of CO 2 , the concentration of formaldehyde, the concentration of fine particulate matter, etc., the amount of fresh air introduced can be increased, and the air quality is sustained in the sixth set time period t6 If the detection result that satisfies the conditions is humidity, the amount of fresh air introduced is reduced, and the humidity in the room rises too quickly. , can avoid causing user discomfort.
　上記は、本発明の好ましい実施形態のみであり、当業者にとって、本発明の技術原理を逸脱しない前提で、若干の改良と置換をすることができ、これらの改良と置換も本発明の範囲内と見なされるべきであることを強調しなければならない。 The above are only preferred embodiments of the present invention, and those skilled in the art can make some improvements and replacements without departing from the technical principles of the present invention, and these improvements and replacements are also within the scope of the present invention.
