Abstract
Description
しかし、上述のように運転中に風路圧損の増減が生じた場合は所定の風量を維持することができない。そのため、ダクトにダンパーを設置して所定の風量へ調整することもある。上述の手法では、所要風量が減少しても送風機の動力負荷はほとんど変化しないため、エネルギーのロスが発生する。
なお、各図において、同一の符号を付したものは、同一のまたはこれに相当するものであり、これは明細書の全文において共通している。
さらに、明細書全文に表れている構成要素の形態は、あくまで例示であってこれらの記載に限定されるものではない。

ダクト4に対して室内機1、2、3を接続し、室内機1、2、3間を通信線5にて通信可能に接続する。通信線5は、有線や無線であってよい。この際、室内機1、2、3のうちの1つを親機として設定し、親機以外のその他の室内機を子機として設定する。ここでは、室内機1を親機とする。室内機2、3を子機とする。
空気調和機100の室内機1が備えるマイコン10には、ファン7の回転数、風量、静圧、電流などのファン特性が記憶されている。
マイコン10を搭載したインバータ9は、ファン7の回転数と電流を検知できる機構を備え、ファン7を駆動するモータ8への電流を変更することでファン7の回転数を変更できる。
室内機1、2、3のマイコン10が通信線5によって相互に通信可能である。
室内機1が備えるマイコン10は、空気調和機100の親機の制御部を構成する。また、室内機2、3が備えるマイコン10は、空気調和機100の子機の制御部を構成する。
次に、図3を参照して空気調和機100の冷房運転時の動作例について説明する。マイコン10によって四方弁103が冷房運転に切り替えられた場合には、冷媒が圧縮機101により圧縮されて高温高圧のガス冷媒となり、四方弁103を介して室外熱交換器104に流入する。室外熱交換器104に流入した高温高圧のガス冷媒は、室外熱交換器104を通過する室外空気と熱交換(放熱)され、高圧の液冷媒となって流出する。室外熱交換器104から流出した高圧の液冷媒は、毛細管105および電子制御式膨張弁106で減圧され、低圧の気液二相の冷媒となり、熱交換器6に流入する。熱交換器6に流入した気液二相の冷媒は、熱交換器6を通過する室内空気と熱交換され、室内空気を冷却して低温低圧のガス冷媒となって圧縮機101に吸入される。
図4は、本発明の実施の形態1に係る空気調和機100の室内機1、2、3の試運転時のフローを示す図である。
まず、図4を用いて空気調和機100の室内機1、2、3の試運転時の制御フローを説明する。
次に、図5を用いて空気調和機100の室内機1に設定された親機の運転時の親機制御フローを説明する。
ステップST2では、親機のマイコン10は、子機の送風量Qのデータを通信線5により受信する。
ステップST3では、親機のマイコン10は、子機からの送風量Qの情報を通信線5により受信すると、ダクト4を一定風量にする所定の風量Q0(基準風量)と全室内機1、2、3の送風量Qの総和(全体の送風量)とから送風過不足量ΔQを計算する。
ステップST4では、親機のマイコン10は、送風過不足量ΔQが存在するか否かを判別する。ステップST4で送風過不足量ΔQが存在する場合(YES)には、ステップST5に移行する。送風過不足量ΔQが存在しない場合(NO)には、ステップST1に移行する。

ここで、変化量ΔAによって最も効率良く駆動可能とは、送風過不足量ΔQが不足の場合には風量を増量するため変化量ΔAが最小値の室内機にてΔAだけ電流値を増加させ、全体の電流量の増加を最少に抑えることをいう。また、送風過不足量ΔQが過剰の場合には風量を減少するため変化量ΔAが最大値の室内機にて変化量ΔAだけ電流値を減少させ、全体の電流量の減少を最大にすることをいう。これにより、電流量を最も効率よく変更する。
ステップST10では、親機のマイコン10は、ファン7の回転数Nを変更する指令に従い、インバータ9を制御して変化量ΔAの変化分だけファン7の回転数Nを変更する。ステップST10からは、ステップST1に戻る。
図6を用いて空気調和機100の室内機2、3の運転時の子機制御フローを説明する。
ステップSH2では、子機のマイコン10は、室内機2、3に対して運転電流値Aと運転回転数Nとを計測し、マイコン10に記憶された関係を用いて送風量Qを計算する。
ステップSH3では、子機のマイコン10は、計算した送風量Qを親機へと通信線5により送信する。
ステップSH5では、子機のマイコン10は、変化量ΔAを、送風過不足量ΔQだけ送風量を変化させた際の電流値A1と現在の電流値Aとの差から計算する。
ステップSH6では、子機のマイコン10は、変化量ΔAを親機に通信線5により送信する。
ステップSH8では、子機のマイコン10は、通信線5を介したファン7の回転数Nを変更する指令に従い、インバータ9を制御して変化量ΔAの変化分だけファン7の回転数Nを変更する。ステップSH8からは、ステップSH1に戻る。
親機のマイコン10が送風過不足量ΔQが存在すると判断すると、通信線5を介して子機のマイコン10に指令を出し、子機のマイコン10に送風過不足量ΔQだけ送風量を変化させた際の電流値A1と現在の電流値Aとの変化量ΔAを計算させ、親機のマイコン10に通信線5により送信させる。親機のマイコン10でも変化量ΔAを計算する。
親機のマイコン10は、送信されてきた親機および各子機の変化量ΔAを比較し、親機および子機の全室内機1、2、3のうち変化量ΔAによって最も効率良く駆動可能な室内機に対してファン7の回転数Nを制御させる指令を通信線5により送信する。
指令を受信した室内機のマイコン10は、変化量ΔAの変化分だけファン7の回転数を変更する。これを繰り返すことで送風量Qを所定の風量Q0へ調整することができる。
