Abstract
Description
(構成)
図1は、本発明の実施の形態1に係る空気調和装置の構成を示す概略図である。
図1に示すように、空気調和装置1は、筐体90を備える。筐体90には、室内吸込口91、室内吹出口92、室外吸込口93、及び室外吹出口94が形成されている。室内吸込口91は、室内から室内空気Aを筐体90内に取り込むための開口である。室内吹出口92は、室内空気Aを室内に吹き出すための開口である。室外吸込口93は、室外から室外空気Bを筐体90内に取り込むための開口である。室外吹出口94は、室外空気Bを室外に吹き出すための開口である。
なお、図2において、z方向は上下方向である。x方向は凝縮器50を通過する室外空気Bの流れ方向である。y方向はz方向及びy方向に直交する方向である。x方向及びy方向は水平面に平行である。
図2に示すように、凝縮器50は、複数の伝熱管51と、複数のフィン52と、第1ヘッダ53と、第2ヘッダ54とを備える。
図3に示すように、複数の伝熱管51は、第1伝熱管51-1及び第2伝熱管51-2を含む。第1伝熱管51-1及び第2伝熱管51-2は、互いに隣り合って配列されている。第1伝熱管51-1及び第2伝熱管51-2は、互いに平行に配列されている。第1伝熱管51-1と第2伝熱管51-2との間に、フィン52が配置されている。
次に、空気調和装置1の動作について説明する。
冷房運転が開始されると、圧縮機20、室内送風機70、及び室外送風機80が動作する。圧縮機20は、低温低圧の冷媒を吸入し、高温高圧の冷媒を吐出する。圧縮機20から吐出された高温高圧の冷媒は、凝縮器50へ流入する。凝縮器50に流入した冷媒は、室外送風機80から送風された室外空気Bと熱交換して放熱し、温度が低下して液状態の冷媒となって、凝縮器50から流出する。凝縮器50から流出した冷媒は、膨張弁30によって減圧されて気液二相状態の冷媒となり、蒸発器40に流入する。蒸発器40に流入した冷媒は、室内送風機70から送風された室内空気Aと熱交換して吸熱、蒸発し、ガス状態の冷媒となって蒸発器40から流出する。蒸発器40から流出した冷媒は、圧縮機20へ吸入される。
以上のように本実施の形態1においては、空気調和装置1は、室内空気Aと冷媒とを熱交換する蒸発器40と、室外空気Bと冷媒とを熱交換する凝縮器50と、蒸発器40で発生した凝縮水Cを凝縮器50へ散水する散水装置100とを備える。凝縮器50は、互いに平行に配列された第1ヘッダ53及び第2ヘッダ54と、第1ヘッダ53と第2ヘッダ54との間に、互いに平行に配列された複数の伝熱管51と、複数の伝熱管51の間に配置されたフィン52とを備える。
このため、散水装置100から凝縮器50へ散水された凝縮水Cが、複数の伝熱管51の間に配置されたフィン52の表面に滞留し易くなり、凝縮器50において蒸発される凝縮水Cの量を向上することができる。また、空気調和装置1は、散水装置100を備えるので、蒸発器40と凝縮器50とを水平方向に離れて配置した場合であっても、蒸発器40で発生した凝縮水Cを凝縮器50へ散水することができる。よって、筐体90内における、蒸発器40と凝縮器50との配置位置の自由度を向上することができる。
このため、凝縮水Cは、第1ヘッダ53の上面から、複数の伝熱管51及び複数のフィン52の表面を伝って第2ヘッダ54まで流れる。よって、凝縮水Cが凝縮器50の表面の全体を伝って流れることとなり、凝縮器50において蒸発される凝縮水Cの量を向上することができる。
このため、第1ヘッダ53からフィン52に伝わった凝縮水Cは、コルゲートフィンであるフィン52の湾曲形状に沿って、湾曲しながら下方へ流れる。即ち、凝縮水Cがフィン52を伝って流れる経路は、第1ヘッダ53と第2ヘッダ54との間の距離と比較して、長くなる。よって、フィン52がプレートフィンである場合と比較して、凝縮水Cがフィン52からの熱を受ける時間が長くなり、凝縮水Cが蒸発し易くなる。したがって、凝縮器50において蒸発される凝縮水Cの量を向上することができる。
このため、凝縮器50が銅製又は鉄製である場合と比較して、凝縮器50を軽量化することができる。
このため、蒸発器40が銅製又は鉄製である場合と比較して、蒸発器40を軽量化することができる。また、蒸発器40が銅製又は鉄製である場合と比較して、蒸発器40で発生した凝縮水Cに、銅イオンなどの、アルミニウムよりも貴となる金属イオンが溶け込むことを抑制することができる。よって、蒸発器40で発生した凝縮水Cが、アルミニウム製である凝縮器50へ散水された場合における、凝縮器50の異種金属接触腐食を防止することができる。
このため、冷媒配管60が銅製又は鉄製である場合と比較して、蒸発器40を軽量化することができる。また、冷媒配管60が銅製又は鉄製である場合と比較して、蒸発器40で発生した凝縮水Cに、銅イオンなどの、アルミニウムよりも貴となる金属イオンが溶け込むことを抑制することができる。よって、蒸発器40で発生した凝縮水Cが、アルミニウム製である凝縮器50へ散水された場合における、凝縮器50の異種金属接触腐食を防止することができる。
このような構成においても、凝縮器50において蒸発される凝縮水Cの量を向上することができる。
上記の説明では、散水装置100は、水ポンプ101と、水配管102と、水散水部103とを有する構成について説明した。散水装置100の構成は、これに限定されない。散水装置100は、蒸発器40で発生した凝縮水Cを凝縮器50へ散水する構成であれば良い。
図4に示すように、筐体90内において凝縮器50の下方には、室外側ドレンパン120が配置されている。室外側ドレンパン120と室内側ドレンパン110とは、水配管121によって連結されている。室内側ドレンパン110に貯水された凝縮水Cは、水配管121を介して、室外側ドレンパン120へ移動する。室外側ドレンパン120は、蒸発器40で発生した凝縮水Cを貯水する。室外側ドレンパン120には散水装置130が配置されている。
このような構成においても、散水装置130から凝縮器50へ散水された凝縮水Cが、フィン52に滞留し、凝縮器50において蒸発される凝縮水Cの量を向上することができる。
以下、実施の形態2における空気調和装置1の構成について、上記実施の形態1との相違点を中心に説明する。なお、上記実施の形態1と同一部分には同一の符号を付し、説明を省略する。
図6は、本発明の実施の形態2に係る空気調和装置の凝縮器を示す上面図である。
図5及び図6に示すように、凝縮器50は、複数の伝熱管51の間にそれぞれ配置された複数のフィン52aを備える。複数のフィン52aは、例えばコルゲートフィンである。散水装置100は、第1ヘッダ53の上面に凝縮水Cを散水する。
このため、第1ヘッダ53の上面に散水された凝縮水Cが、第1ヘッダ53の縁部から複数のフィン52aを伝って下方に流れる際、複数のフィン52aの表面に凝縮水Cが付着し易くなる。よって、散水装置100から凝縮器50へ散水された凝縮水Cが、複数のフィン52aの表面に滞留し易くなり、凝縮器50において蒸発される凝縮水Cの量を向上することができる。
以下、実施の形態3における空気調和装置1の構成について、上記実施の形態1及び2との相違点を中心に説明する。なお、上記実施の形態1及び2と同一部分には同一の符号を付し、説明を省略する。
図7に示すように、凝縮器50の第1ヘッダ53aは、上面が水平面に対して上方に突出した曲面である。具体的には、第1ヘッダ53aの上面は、室外空気Bの流れ方向において、中央が上方に突出し端部が下方に向かって傾斜する凸状の曲面形状を有している。このような構成により、第1ヘッダ53aの上面に散水された凝縮水Cが、曲面に沿って下方へ流れる。
このため、凝縮水Cが凝縮器50の上方から散水された場合でも、第1ヘッダ53aの上面に凝縮水Cが滞留し難くなる。よって、散水装置100から凝縮器50へ散水された凝縮水Cが、複数のフィン52へ到達し易くなり、凝縮器50において蒸発される凝縮水Cの量を向上することができる。
図8は、本発明の実施の形態3に係る空気調和装置の凝縮器の変形例を示す斜視図である。
図8に示すように、凝縮器50の第1ヘッダ53bは、上面が水平面に対して傾斜する傾斜面である。具体的には、第1ヘッダ53bの上面は、室外空気Bの流れ方向において、中央部を頂点とし両端部へ向かって傾斜する傾斜面によって構成されている。このような構成により、第1ヘッダ53bの上面に散水された凝縮水Cが、傾斜面に沿って下方へ流れる。
以下、実施の形態4における空気調和装置1の構成について、上記実施の形態1~3との相違点を中心に説明する。なお、上記実施の形態1~3と同一部分には同一の符号を付し、説明を省略する。
図10は、本発明の実施の形態4に係る空気調和装置の凝縮器を示す縦断面図である。なお、図10は、凝縮器50をxy平面で切断した断面を示している。
図9及び図10に示すように、凝縮器50の第2ヘッダ54aは、上面が下方に凹んで形成された貯水部56を有する。具体的には、第2ヘッダ54aの上面において、縁部55が上方に突出し、縁部55によって囲まれた内側に貯水部56が形成されている。
このため、一部の凝縮水Cが蒸発しきれずに第2ヘッダ54aに到達した場合であっても、凝縮水Cが凝縮器50の下方へ流れ出ること防止できる。また、貯水部56に貯水された凝縮水Cは、第2ヘッダ54a内の冷媒によって加熱され、蒸発が促進されるため、凝縮器50において蒸発される凝縮水Cの量を向上することができる。
以下、実施の形態5における空気調和装置1の構成について、上記実施の形態1~4との相違点を中心に説明する。なお、上記実施の形態1~4と同一部分には同一の符号を付し、説明を省略する。
図11に示すように、空気調和装置1は、イオン交換樹脂140を備える。イオン交換樹脂140は、蒸発器40で発生した凝縮水Cに含まれた、アルミニウムよりも貴となる金属を除去する機能を有する。イオン交換樹脂140は、イオン交換による平衡反応によって、予め吸着されたイオンと目的物質とを交換することで、目的物質を吸着するものである。イオン交換樹脂140は、例えば、凝縮水Cに含まれた銅イオンを目的物質として吸着し、凝縮水Cから除去するものである。
このため、凝縮水Cが凝縮器50に散水される前にイオン交換樹脂140でアルミニウムよりも貴となる金属イオンを除去することができる。そのため、凝縮水Cに含まれる、アルミニウムよりも貴となる金属イオンの量を低減できる。よって、凝縮器50の複数の伝熱管41及び複数のフィン42が、アルミニウム製である場合であっても、凝縮器50の異種金属接触腐食を防止することができる。
散水装置100の構成は、図11に示した構成に限定されない。散水装置100は、蒸発器40で発生した凝縮水Cを凝縮器50へ散水する構成であれば良い。また、イオン交換樹脂140は、凝縮水Cが凝縮器50に散水される前に、凝縮水Cに含まれたアルミニウムよりも貴となる金属を除去する構成であれば良い。
本変形例における空気調和装置1は、上記実施の形態1において説明した空気調和装置1の構成の変形例(図4)の構成に加え、イオン交換樹脂140を備えている。
図12に示すように、イオン交換樹脂140は、室外側ドレンパン120に配置されている。イオン交換樹脂140は、室外側ドレンパン120に貯水された凝縮水Cから、アルミニウムよりも貴となる金属を除去する。なお、イオン交換樹脂140の配置位置はこれに限定されず、室内側ドレンパン110、水配管121、又は散水装置130に配置されていても良い。
