Abstract
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、この換気システム(S)は、2つの換気装置(10)(第1換気装置(10a)及び第2換気装置(10b))と、ブースタファン(1)とを有している。
図6は、本発明の実施形態2を示し、上記実施形態1とは、換気装置(10)の数が異なっているとともに、給気ファン(26)の空回りを防止するための空回り防止機構を備える点で異なっている。尚、図1と実質的に同じ構成要素については同じ符号を付してその詳細な説明を適宜省略する。また、以下の実施形態において、ブースタファン(1)の配置や空気通路(61~67)の構成は実施形態1と同様であるため、その説明を省略する。
図8乃至図14は、本発明の実施形態3を示し、上記実施形態2とは換気装置(10a)の構成及び空回り防止機構の構成を異ならせたものである。なお、図6と実質的に同じ構成要素については同じ符号を付してその詳細な説明を適宜省略する。
上記冷媒回路(50)について、図13を参照しながら説明する。
第1吸着熱交換器(51)と第2吸着熱交換器(52)のそれぞれは、フィン・アンド・チューブ熱交換器の表面に吸着剤を担持させたものである。
換気装置(10a)は、図3に示すコントローラ(100)によって制御されている。コントローラ(100)は、上記各実施形態と同様に、給気ファン(26)及び排気ファン(25)の作動制御、並びに、ブースタファン(1)の作動制御を行うとともに、各ダンパ(41~48,83,84)の開閉、圧縮機(53)の運転容量や電動膨張弁(55)の開度の調節、四方切換弁(54)の切り換え等を行う。
本実施形態の換気装置(10a)は、三つの運転モード(除湿換気運転、加湿換気運転、単純換気運転)を実行可能である。つまり、この換気装置(10a)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。本実施形態では、ユーザは、不図示の操作スイッチを操作することで所望の運転モードの選択や、換気装置(10a)の作動/停止を切り換え可能になっている。
除湿換気運転中の換気装置(10a)は、後述する第1動作と第2動作が所定の時間間隔(例えば3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)及び第2バイパス用ダンパ(84)は、常に閉状態となる。
加湿換気運転中の換気装置(10a)は、後述する第1動作と第2動作が所定の時間間隔(例えば3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)及び第2バイパス用ダンパ(84)は、常に閉状態となる。
単純換気運転中における換気装置(10a)の動作について、図12を参照しながら説明する。この単純換気運転は、外気をそのまま室内(30)へ供給しても室内(30)の快適性が損なわれない時期(例えば、春季や秋季などの中間期)に行われる。つまり、この単純換気運転は、室内(30)へ供給される空気の湿度調節は不要であるが、室内(30)の換気は行う必要がある場合に実行される。
コントローラ(100)は、上記操作スイッチからの情報を基に、ユーザが要求する運転モードを識別するとともに、換気装置(10a)の作動要求の有無を判定する。コントローラ(100)は、換気装置(10a)が停止状態にあり且つ運転モードとして単純換気運転モードが選択されている場合において、換気装置(10a)の作動要求があったときには、各ダンパ(41~48,83,84)をそれぞれ、上述した所定の状態に制御するとともに、給気ファン(26)及び排気ファン(25)、並びにブースタファン(1)を作動させる。その際、コントローラ(100)は、換気装置の作動要求があってから、給気ファン(26)が作動するまで(給気ファン(26)の運転センサ(17)から作動検知信号を受信するまで)の間は、第1バイパス用ダンパ(83)を閉状態に維持する一方、給気ファン(26)が作動した以後は、第1バイパス用ダンパ(83)を開状態に維持するようになっている。したがって、給気ファン(26)が作動するまでは、ブースタファン(1)と給気ファン(26)との間の空気通路を、第1バイパス用ダンパ(83)により遮断することができ、これにより、給気ファン(26)が、ブースタファン(1)からの空気流により空回りしている最中に起動するのを防止することができる。よって、給気ファン(26)をその起動時の突入電流から保護することができる。
本発明の構成は、上記実施形態に限定されるものではなく、それ以外の種々の構成を包含するものである。
