Description
図1は、本発明の実施形態に係る換気システム(S)を示している。この換気システム(S)は、複数の換気装置(4,10a,…)と換気コントローラ(5)を備えて構成されている。換気装置(4,10a,…)には、第1調湿換気装置(10a)〜第N調湿換気装置(10n)とブースタファン(4)が含まれている。
次に、換気システム(S)における各調湿換気装置(10a〜10n)を各集合ダクト(1,2,3)毎に分けるグループ分けの手順について図2に基づいて説明する。尚、本実施形態では、各調湿換気装置(10a〜10n)のダクト接続について、集合給気ダクト(1a,2a,3a)とのダクト接続のみ説明する。集合排気ダクト(1b,2b,3b)については、集合給気ダクト(1a,2a,3a)と同様であるので説明を省略する。換気システム(S)は、換気コントローラ(5)にN台の接続機器である調湿換気装置(10a〜10n)と1台のブースタファン(4)が接続されて構成されている。尚、本判定手順において、換気システム(S)に接続される接続機器の総数をX台(X=N+1,X≧2)として説明する。
調湿換気装置(10)について、図5〜図8を適宜参照しながら説明する。なお、ここでの説明で用いる「上」「下」「左」「右」「前」「後」「手前」「奥」は、特にことわらない限り、調湿換気装置(10)を前面側から見た場合の方向を意味している。
図9に示すように、冷媒回路(50)は、第1吸着熱交換器(51)、第2吸着熱交換器(52)、圧縮機(53)、四方切換弁(54)および電動膨張弁(55)が設けられた閉回路である。この冷媒回路(50)は、充填された冷媒を循環させることによって、蒸気圧縮冷凍サイクルを行う。
調湿換気装置(10)には、制御部としての調湿コントローラ(100)が設けられている。本実施形態の調湿換気装置(10)では、制御用基板(91)に設けられたマイコンが調湿コントローラ(100)を構成している。調湿コントローラ(100)には、内気湿度センサ(96)、内気温度センサ(98)、外気湿度センサ(97)および外気温度センサ(99)の計測値が入力されている。また、調湿コントローラ(100)には、冷媒回路(50)に設けられた各センサ(91,92,…)の計測値が入力されている。調湿コントローラ(100)は、入力されたこれらの計測値に基づいて、調湿換気装置(10)の運転制御を行う。調湿換気装置(10)では、調湿コントローラ(100)の制御動作によって、後述する除湿換気運転と加湿換気運転と単純換気運転とが切り換えられる。また、調湿コントローラ(100)は、これらの運転中において、各ダンパ(41〜48)、各ファン(25,26)、圧縮機(53)、電動膨張弁(55)および四方切換弁(54)の動作を制御する。
本実施形態の調湿換気装置(10)は、除湿換気運転と、加湿換気運転と、単純換気運転とを選択的に行う。この調湿換気装置(10)は、除湿換気運転と加湿換気運転とを通常運転として行う。
除湿換気運転中の調湿換気装置(10)では、後述する第1通常動作と第2通常動作が所定の時間間隔(例えば3〜4分間隔)で交互に繰り返される。この除湿換気運転中において、第1バイパス用ダンパ(83)および第2バイパス用ダンパ(84)は、常に閉状態となる。
加湿換気運転中の調湿換気装置(10)では、後述する第1通常動作と第2通常動作が所定の時間間隔(例えば3〜4分間隔)で交互に繰り返される。この加湿換気運転中において、第1バイパス用ダンパ(83)および第2バイパス用ダンパ(84)は、常に閉状態となる。
単純換気運転中の調湿換気装置(10)は、取り込んだ室外空気(OA)をそのまま供給空気(SA)として室内へ供給すると同時に、取り込んだ室内空気(RA)をそのまま排出空気(EA)として室外へ排出する。ここでは、単純換気運転中の調湿換気装置(10)の動作について、図14を参照しながら説明する。
上記本実施形態によれば、第N調湿換気装置(10n)の給気ファン(25)(又は排気ファン(26))の回転数を変化させて第1〜第(N−1)調湿換気装置(10a,10b,10c,…)の消費電力が変化することで第N調湿換気装置(10n)の第1〜第(N−1)調湿換気装置(10a,10b,10c,…)と同じ集合給気ダクト(1a,2a,3a)への接続を自動判定したため、第N調湿換気装置(10n)が接続される集合給気ダクト(1a,2a,3a)を自動で判定することができる。この結果、換気システム(S)における風量調整を正確に行うことができる。
次に、本実施形態の変形例について説明する。上記実施形態では、吸着剤として、ゼオライトやシリカゲル等の主に水蒸気の吸着を行う材料と用いたが、本発明はこれに限られず、水蒸気の吸着と吸収の両方を行う材料(いわゆる収着剤)を用いてもよい。
本発明は、上記実施形態について、以下のような構成としてもよい。
1a 第1集合給気ダクト
1b 第1集合排気ダクト
2 第2集合ダクト
