Description
本願は、2022年4月15日に日本に出願された特願2022-067587号について優先権を主張し、その内容をここに援用する。
以下、本開示の実施形態に係る空気調和システムの制御装置、空気調和システムの制御方法、プログラム、及び空気調和システムについて、図1~図4を参照して説明する。
図1に示すように空気調和システム1は、室内機2と、室外機(図示せず)と、制御装置4と、を主に備える。
室内機2は、室内に設置される。
室内機2と室外機とは、冷媒配管(図示せず)によって接続されている。
室内機2は、室内の空気を吸い込んで温度や湿度の調整を行った後、空気を室内に吹き出すことで、室内の空気調和を行う。
室内機2は、室内の壁面の上部に固定される。
室内機2は、筐体20と、本体21と、を備える。
筐体20は、背面パネル20bと、前面パネル20fと、天面パネル20tと、底面パネル20dと、一対の側面パネル(図示せず)と、を備える。
本明細書において、壁面に固定される背面パネル20b側を後方、背面パネル20bとは反対側の前面パネル20f側を前方として説明を行う。
前面パネル20fは、本体21を前方から覆う。
天面パネル20tは、本体21を上方から覆う。
天面パネル20tには、筐体20内に室内の空気を吸い込む吸込口(図示せず)が設けられる。
底面パネル20dは、筐体20の底部に設けられる。
底面パネル20dは、本体21を下方から覆う。
底面パネル20dには、吹出口20hが形成される。
吹出口20hは、底面パネル20dを上下に貫通するように形成される。
吹出口20hは、筐体20の幅方向(図1において紙面に直交する方向)に延びている。
室内熱交換器22は、送風ファン23を外周側から囲むように設けられる。
室内熱交換器22は、室外機(図示せず)から送給される冷媒と、本体21内の雰囲気との熱交換を行う。
室内熱交換器22の下側には、熱交換によって筐体20内の空気が凝縮(結露)することによって生じた結露水を受けるドレンパン(図示せず)が設けられる。
ドレンパンで受けた結露水は、ドレンパンに接続された排水管(図示せず)を通して室外に排出される。
送風ファン23の回転により、筐体20内で風が発生される。
送風ファン23の回転により、筐体20の外部の空気が、吸込口(図示せず)から筐体20内に吸い込まれる。
送風ファン23の背面側から吹出口20hにわたって、空気の流れ方向を案内する案内板26が設けられている。
筐体20内に吸い込まれた空気は、室内熱交換器22に流通され、冷媒との熱交換がなされる。
室内熱交換器22で熱交換がなされた空気は、案内板26に沿って吹出口20hへと案内され、吹出口20hから室内に吹き出される。
フラップ24は、筐体20の幅方向(図1の紙面に直交する方向)に延びる回転軸周りに回動可能に設けられる。
フラップ24は、吹出口20hを開閉する。
フラップ24は、空気調和システム1の運転時に開状態となる。
フラップ24は、空気調和システム1の停止時には閉状態となり、吹出口20hを覆う。
フラップ24は、その開度を調整することで、吹出口20hから吹き出す吹出風の風向を調整可能である。
オゾン発生器25は、オゾン(O3)を発生し、筐体20内に放出する。
オゾン発生器25は、例えば、放電式のオゾン発生器である。
オゾン発生器25は、放電式以外のものであってもよい。
制御装置4は、室内機2の動作を制御する。
図2に示すように、制御装置4は、Central Processing Unit(以下、「CPU」という。)41と、メモリ42と、を備える。
すなわち、CPU41は、所定のプログラムに基づいて動作することで、運転制御部411、オゾン照射制御部412、及びフラップ制御部413としての機能を発揮する。
メモリ42は、制御装置4が取得する各種データを格納する。
運転制御部411は、冷房モード、除湿モード、暖房モード、送風モードなど、予め設定された各種運転モードで室内機2を運転する。
運転制御部411は、リモートコントローラ(図示せず)に対するユーザの操作入力、タイマー等の設定入力等により、所定の運転モードで室内機2を運転する。
運転制御部411は、冷房モード、又は除湿モードによる運転の終了時に、後に詳述するような内部クリーン運転を、室内機2に実施させる。
オゾン照射制御部412は、オゾン発生器25によりオゾンを発生させる。
オゾン照射制御部412は、オゾン発生器25により発生したオゾンを、室内熱交換器22に照射させる。
乾燥状態でカビ等の微生物(菌)にオゾンガスを接触させるだけでは、除菌効果が小さい。そこで、オゾン照射制御部412は、室内熱交換器22の表面が、室内熱交換器22における熱交換によって生じる結露水によって湿潤状態にあるときに、オゾンを室内熱交換器22に照射させる。
湿潤状態にある室内熱交換器22に、オゾンを照射させると、筐体20内の空気中のオゾンが水に溶け込む。これにより、除菌効果が向上する。なお、水と微生物の親和性が高いことも、除菌効果の向上に関係すると考えられる。
図3に示すように、本開示の実施形態に係る空気調和システム1の制御方法S10は、室内熱交換器にオゾンを照射するステップS11と、室内熱交換器を乾燥させるステップS12と、送風ファンにより送風させるステップS13と、を含む。
本実施形態において、空気調和システム1の制御方法S10は、室内機2の冷房モード、又は除湿モードによる運転を停止した場合、自動的に実行される。
室内機2が冷房モード、又は除湿モードによる運転を行っている場合、室内熱交換器22の表面は、結露した水(結露水)によって湿潤する(濡れる)。
室内機2が冷房モード、又は除湿モードによる運転を停止した直後において、室内熱交換器22の表面は、結露水によって湿潤している。
室内熱交換器にオゾンを照射するステップS11では、室内熱交換器22が湿潤した状態で、図4に示すように、オゾン発生器25をONに切り換え、オゾン発生器25でオゾンを発生させる。
オゾン発生器25で発生されたオゾンは、室内熱交換器22に照射される。
室内熱交換器にオゾンを照射するステップS11では、冷房モードによる運転を停止し、送風ファン23をOFFとする。
室内熱交換器にオゾンを照射するステップS11では、フラップ24を開く。
室内熱交換器にオゾンを照射するステップS11では、室内熱交換器22が湿潤した状態で、オゾンを室内熱交換器22に照射することで、室内熱交換器22に付着したカビ等の菌が低減される。
室内熱交換器を乾燥させるステップS12では、図4に示すように、運転制御部411により室内機2を暖房モードで運転させ、送風ファン23をONに切り換える。これにより、オゾンが照射されて湿潤した状態の室内熱交換器22が加熱され、室内熱交換器22が乾燥される。
室内熱交換器を乾燥させるステップS12では、室内熱交換器22の温度が室内機2の内部温度以上、かつ45℃未満を維持するように、室内熱交換器22を加熱するのが好ましい。
室内熱交換器を乾燥させるステップS12では、室内熱交換器22の温度が、例えば、30℃以上、かつ45℃未満を維持するように、室内熱交換器22を加熱するのが好ましい。
室内熱交換器を乾燥させるステップS12では、室内熱交換器22の温度が、例えば、35℃以上、かつ45℃未満を維持するように、室内熱交換器22を加熱するのが特に好ましい。
室内熱交換器22を乾燥させるステップS12では、吹出風Wが室内機2の前方に向かうよう、フラップ制御部413によりフラップ24を制御する。
室内熱交換器22を乾燥させるステップS12では、吹出風Wは、フラップ24により、吹出口20hから室内機2の前方に向かって流れるように案内される。
吹出風Wの温度は、室温よりも高い。このため、吹出風Wの一部は、室内で上昇し、室内機2の前面に沿うように流れる。これにより、室内機2の周辺の温度が上昇し、室内機2の内部と外部との温度差が抑えられる。
また、フラップ24により、室内機2から流出する暖気が室内機2の下方に向かうことが抑えられる。
予め設定した所定時間の経過後、室内熱交換器22を乾燥させるステップS12を終了する。
このように、室内熱交換器22の乾燥後に、送風ファン23で送風することによって、室内熱交換器22の表面に残存する水分を、より一層低減する。
予め設定した所定時間の経過後、送風ファンにより送風させるステップS13を終了する。
本実施形態では、空気調和システム1の制御装置4は、室内熱交換器22が湿潤した状態で、オゾンを室内熱交換器22に照射する。これにより、室内熱交換器22に付着したカビ等の菌が低減される。
さらに、制御装置4は、オゾンが照射され、湿潤したままの状態の室内熱交換器22を乾燥させる。これにより、室内熱交換器22の表面に残存する水分の量を低減させる。
したがって、室内機2の停止中に、カビ等の菌が繁殖することが抑えられる。
室内熱交換器22を乾燥させる際には、室内機2を暖房モードで運転させる。このとき、室内熱交換器22の温度が、室内機2の内部温度以上、かつ45℃未満を維持するように室内熱交換器22を加熱する。したがって、室内熱交換器22から室内に流出する暖気の量を抑え、室内の温度上昇を抑えることができる。
室内熱交換器22を乾燥させる際に、温度を高くしすぎると、室内機2の筐体の内側と外側との温度差が大きくなり、筐体の表面に結露が生じることがある。これに対し、制御装置4は、室内熱交換器22の温度を45℃未満に抑える。これにより、筐体の表面への結露の発生が抑えられる。
このようにして、室内環境への影響を抑えつつ、カビの成長を抑制することが可能となる。
また、吹出風Wが室内機2の前方に向かうように、フラップ24の開度を調整することで、室内機2から流出する暖気が室内機2の下方に向かうことが抑えられる。利用者は、室内で室内機2よりも下方の空間に存在することが多い。したがって、利用者に、室内熱交換器22を乾燥させるために発生させる暖気が到達することが抑えられる。
なお上記実施形態では、室内熱交換器にオゾンを照射するステップS11で、冷房モードによる運転を停止し、送風ファン23をOFFとするようにしたが、これに限られない。例えば、図5に示すように、オゾンを照射するステップS11で、運転制御部411により室内機2を冷房モードまたは除湿モードで運転させ、送風ファン23をONとしながら、室内熱交換器22にオゾンを照射するようにしてもよい。(なお、その後のステップS13における送風運転は実施しなくてもよい。)
これにより、オゾンを照射する際に、冷房モードまたは除湿モードで室内機2を運転することで、室内熱交換器22の周囲で空気中の水分が結露し、結露水が生成される。生成された結露水は、室内熱交換器22からドレンパン(図示せず)に落下し、排水管から外部に排出される。これにより、オゾンの照射によって死滅したカビ等の菌が、結露水とともに排出される。これにより、カビの発生が、より有効に抑えられる。
記憶/再生装置50は、CD-ROM、DVD、フラッシュメモリ等の外部メディアへデータ等を記憶したり、外部メディアのデータ等を再生したりするための装置である。
IO I/F51は、制御装置4と他の装置との間で情報等の入出力を行うためのインタフェースである。
通信I/F52は、インターネット、専用通信回線等の通信回線を介して、他の装置との間で通信を行うインタフェースである。
