本願は、2016年10月14日に、日本に出願された特願2016-203001号に基づき優先権を主張し、その内容をここに援用する。
しかしながら、空気熱交換室の下端の幅と等しい幅とされたドレンパンの中央部にヒータを貼り付けることは困難であった。つまり、ドレンパンに対する作業が困難であった。
そして、バッフルプレートの幅方向において、ドレンパンの外側壁と熱交換室の幅方向の端及びバッフルプレートの幅方向の端部との間に隙間を設けることで、隙間を介して、幅の狭いドレンパン内に溜まる塵や埃を容易に掃除することができる。
図1は、本発明の第1の実施形態に係る空冷チラーの外観を示す斜視図である。図1において、X方向は機械室11、熱交換室12、バッフルプレート15、及びドレンパン17の幅方向(所定方向に対して直交する方向)、Y方向はX方向に対して直交する機械室11、熱交換室12、バッフルプレート15、及びドレンパン17の長さ方向(所定方向)、Z方向はXY平面に対して直交する鉛直方向をそれぞれ示している。
図2は、図1に示す領域Aを拡大した正面図である。図2において、図1に示す構造体と同一構成部分には、同一符号を付す。
圧縮機、四方切換え弁、水熱交換器、及び膨張弁は、冷媒配管を介して接続されている。水配管は、水熱交換器及び水循環ポンプと接続されている。
空冷チラー10は、四方切換え弁を切り替えることで、冷房運転と、暖房運転と、の両方の運転に対応可能な構成とされている。
水熱交換器は、冷媒配管を流れる冷媒と、水配管を流れる水と、を熱交換させる。
膨張弁は、水熱交換器と熱交換室12との間に設けられている。膨張弁は、熱交換室12を構成する複数の熱交換部12Aと接続されている。
水循環ポンプは、機械室11を構成する複数の水熱交換器に水を供給する。
筐体28の側壁部分は、機械室11に対して熱交換室12を支持している。筐体28は、外気(空気)を取り込む側壁部28Aを有する。複数のファン13が回転することで、側壁部28Aを介して、筐体28内に外気(空気)が取り込まれる。
複数の伝熱チューブ内には、圧縮機により冷媒が循環されている。熱交換部12Aでは、複数の伝熱チューブと側壁部28Aを介して吸い込まれた外気(空気)とが熱交換する。
バッフルプレート15は、熱交換室12の下端12aに固定された状態において、両端部15Aが熱交換室12の幅方向(X方向)の外側に延出している。バッフルプレート15の端部15Aは、その下方に配置されたドレンパン17と対向するように配置されている。バッフルプレート15の両端部15Aの先端は、その下方に向かう方向に折れ曲がったL字形状とされている。
このような構成とされた複数の貫通部15Bをバッフルプレート15に設けることにより、複数の貫通部15Bを介して、ドレンパン17にドレン水を導くことが可能となるので、バッフルプレート15の両端部15Aからドレン水が溢れ出すことを抑制できる。
上述したバッフルプレート15の材料としては、例えば、耐水性に優れたステンレス鋼を用いることが可能である。
図5は、図2に示す一対のドレンパン及び連結用ドレンパンの平面図である。図5において、図1、図2、及び図4に示す構造体と同一構成部分には、同一符号を付す。
なお、以下の説明では、一方の端17Aと他方の端17Bとの両方を指す場合には、両端17A,17Bと記載する場合がある。
このように、一方の端17Aが他方の端17Bよりも機械室11の上面11aに近づくように、ドレンパン17を傾斜させて配置することにより、容易にドレン水を連結用ドレンパン19に案内することができる。
このように、X方向において、ドレンパン17の外側壁17Cと熱交換室12の端12B及びバッフルプレート15の幅方向の端部15Aとの間に隙間26を設けることで、隙間26を介して、幅の狭いドレンパン17に溜まる塵や埃を容易に掃除することができる。
隙間26の幅は、ドレンパン17の内側を掃除する際に使用する掃除道具が挿入可能な大きさとされている。隙間26の幅は、例えば、12mm以上にするとよい。
連結用ドレンパン19の中央部には、排出管24と接続された排出口19Cが設けられている。排出口19Cは、排出管24を介して、ドレンパン17を経由したドレン水を空冷チラー10の外部に排出する。
このように、2つのドレンパン17の一方の端17Aを連結する連結用ドレンパン19と、連結用ドレンパンに設けられた排出口19Cと、を有することで、排出口19Cの数を1つにすることが可能となるので、排出口の数を複数設けた場合と比較して、排出口19Cの掃除を簡便に行うことができる。
このように、連結用ドレンパン19の形状をV字形状とすることで、連結用ドレンパン19の中央に設けられた排出口19Cに、ドレンパン17を経由したドレン水を効率良く案内することができる。
そして、X方向において、ドレンパン17の外側壁17Cと熱交換室12の端12B及びバッフルプレート15の端部15Aとの間に隙間26を設けることで、隙間26を介して、幅の狭いドレンパン17に溜まる塵や埃を容易に掃除することができる。
また、第1の実施形態では、ドレンパン17を傾斜させた場合を例に挙げて説明したが、ドレンパン17は、XY平面に対して水平となるように配置させてもよい。この場合、溜まったドレン水をドレンパン17から効率良く抜き出す観点から、ドレンパン17のY方向に複数の排出口19Cを設けるとよい。
図6は、本発明の第2の実施形態に係る空冷チラーの主要部の正面図である。図6において、図2に示す構造体と同一構成部分には同一符号を付す。
図7は、図6に示すバッフルプレートの平面図である。図7において、図6に示す構造体と同一構成部分には同一符号を付す。
このように、Z方向において、熱交換室12の端12Bとドレンパン17とが対向するように配置することで、熱交換室12の端12Bを介して、バッフルプレート31の端部31Aよりも外側に移動したドレン水をドレンパン17に落下させることができる。
バッフルプレート31の両端部31Aは、先端が下方に折れ曲がったL字形状とされている。バッフルプレート31の先端は、ドレンパン17の側壁の内面と接触している。バッフルプレート31の先端は、例えば、ボルトやねじを用いて、ドレンパン17に固定されている。
図8は、本発明の第3の実施形態に係る空冷チラーの主要部の正面図である。図8において、図2に示す構造体と同一構成部分には同一符号を付す。
図9は、図8に示す一対のドレンパンの平面図である。図9において、図8に示す構造体と同一構成部分には同一符号を付す。
