Description
NOXガスの変化率が第3の閾値(B)以下であり、かつ、炭化水素ガスの変化率が第4の閾値(C)以下であるか否かを検出するステップと、NOXガスの変化率が第3の閾値(B)以下であり、かつ、炭化水素ガスの変化率が第4の閾値(C)以下であると検出された後に、NOXガスの変化率が第3の閾値(B)以上に設定される第5の閾値(D)以上になったか否かを検出するステップと、NOXガスの変化率が第5の閾値(D)以上になったことを検出した場合に、所定の時間、NOXガスの変化率の値を第1の閾値よりも小さい所定の値にセットして、フレッシュ・エアモードから再循環モードへの切り替えが行われないようにするステップと、を備えることを特徴とする。
本発明の特徴を以下に列挙する。空気取入れを制御する方法は、NOXガスまたはH/Cガスについての変化率の計算から誘導される。H/Cガスについては、センサの反応によってセンサ出力電圧の低下が発生し、その結果変化率の減少が起こる。空気質のレベルにおける所望の転換点に対応する較正された閾値(単数または複数)を、当該システムについて選択することができる。H/Cガスの場合、取入れ状態の転換(再循環)は、典型的には変化率が閾値のレベル以下に低下した時に行われる。NOXガスについても基本的な考えは同様であるが、方向は逆である。NOXガスは高濃度で存在する場合、センサ電圧の上昇を引き起こし、したがって変化率を大きくする。NOXガスの場合、変化率が較正された閾値を上回ったときに再循環への切り換えが行なわれる。

- 過去に検出された複数のNO X ガスの値を用いてNO X ガスの基準値を算出し、現在のNO X ガスの値を前記算出したNO X ガスの基準値で除算して、空調される閉鎖空間(16)の外部におけるNOXガスの変化率を求めるステップと、
前記閉鎖空間(16)外部における炭化水素ガスの変化率を前記炭化水素ガスの基準値に関連して検出するステップと、を有し、
前記NOXガスの変化率が第1の閾値である高NOX閾値を上回ったとき、または前記炭化水素ガスの変化率が第2の閾値である低H/C閾値を以下に低下したときに、換気用取入れ扉を制御して、空気を外部から前記閉鎖空間に取り入れる「フレッシュ・エアモード」から空気を前記閉鎖空間で循環させる「再循環モード」に切り替える空気取入れの制御方法であって、
前記NOXガスの変化率が第3の閾値(B)以下であり、かつ、前記炭化水素ガスの変化率が第4の閾値(C)以下であるか否かを検出するステップと、
