Description

【０００１】
【発明の属する技術分野】
本発明は、室内熱交換器と室外熱交換器とを本体内に収容する、いわゆる一体形の空気調和機において、冷房運転時に室内熱交換器で生成されるドレン水の処理構造の改良に関する。
【０００２】
【従来の技術】
たとえば、エレベータ装置を構成するゴンドラ（以下、単にエレベータと言う）天井部に、エレベータ内部を冷房し、もしくは暖房する空気調和機が載設される。この空気調和機は、冷凍サイクルを利用し、本体内に室内熱交換器と室外熱交換器を備えた、いわゆる一体形のものが用いられる。
【０００３】
冷房運転時には、室内熱交換器で熱交換される空気の露点が低下して水分が凝縮し、ドレン水となって滴下する。この熱交換器の下部にはドレンパンが配置され、全てのドレン水が集溜される。ドレン水は室外熱交換器側に導びかれて掻き上げられ、この熱交換器に散水することで熱交換効率の向上化を得るとともに、ドレン水の蒸発処理がなされる。
【０００４】
具体的には、ドレン水をドレンポンプで汲み上げて室外熱交換器の上端から垂れ流す。あるいは、室外送風機を構成するプロペラファンの外周端に沿ってスリンガリングを取付け、ファンで室外熱交換器に外気を送風するとともにスリンガリングがドレン水を掻き上げて室外熱交換器に降りかける。
【０００５】
【発明が解決しようとする課題】
しかしながら、ドレンポンプによるドレン水の汲み上げ方式では、平面視で幅方向にわずかな寸法で、かつ長手方向に極端に長い室外熱交換器に対してドレン水を均一に散布することができず、ドレン水の蒸散性能が低い。従来、親水性の高い不織布等を用いて均一散布の対応をなしているが、ゴミによる目詰まりなどの問題が生じ易い。
【０００６】
また、スリンガリング方式では、プロペラファンは比較的直径が大であって、スリンガリングがドレン水を掻き上る際の音が大きい。室外熱交換器に対して外気とドレン水を吹付けるので、室外熱交換器での風切り音と、ドレン水が室外熱交換器に叩きつけられる音が重なり、騒音が大であるとともに室外熱交換器の性能悪化の要因となっている。
【０００７】
本発明は、上述の事情を考慮してなされたものであり、その目的とするところは、本体内に室内熱交換器と室外熱交換器とを収容配置した一体形で、かつ室内熱交換器で生成されるドレン水を室外熱交換器へ飛散させて蒸発処理することを前提として、風切り音等の騒音の低減を得るとともにドレン水蒸散効率向上化と、室外熱交換器の熱交換性能向上化を得られる空気調和機を提供しようとするものである。
【０００８】
【課題を解決するための手段】
本発明の空気調和機は上述の目的を満足するためになされていて、筐体からなる空気調和機本体と、この空気調和機本体内に仕切り手段を介して設けられる室内側ユニット部および室外側ユニット部とを具備し、
上記室内側ユニット部は、室内吸込み口および室内吹出し口と、室内吸込み口から吸込まれた空気と熱交換し、かつドレン水を受けるドレンパン上に立位する室内熱交換器と、室内吸込み口から室内空気を吸込んで室内熱交換器に導き熱交換した空気を室内吹出し口から室内へ送風する室内送風機とを備え、
上記室外側ユニット部は、空気調和機本体の側面板に設けられる外気吸込み口、および背面板に設けられる吹出し口と、空気調和機本体内部に背面板と所定の空間を存して長手方向のほぼ中央部に、背面板と略平行な略方向な幅方向に亘って配置され、所定間隙を存して並置される複数枚のフィンに熱交換パイプを貫通させた、いわゆるフィンドチューブタイプであり、少なくとも一方端側は所定曲率で曲成する曲成部が設けられるとともに、各曲成部から側面板に沿って直状に延出し外気吸込み口に対向する延設部が連設される室外熱交換器と、この室外熱交換器と背面板との空間に配置され外気吸込み口から吸込んだ外気を室外熱交換器を介して吹出し口から外部へ吹出す室外送風機と、室外送風機とは室外熱交換器を介して反対側の部位に、回転にともなってドレンパンから導いたドレン水を遠心方向に掻き上げる掻き上げ用円板を備え、この掻き上げ用円板の遠心方向が室外熱交換器の曲成部と対向するよう配置される複数の掻き上げ手段とを具備し、
上記複数の掻き上げ手段におけるそれぞれの掻き上げ用円板は駆動モータの回転軸に取付けられるとともに室外熱交換器の平面視における中心に対して所定方向に位置をずらして配置され、かつ制御装置によって室外送風機の運転と停止に同期して運転と停止するよう制御され、冷房運転時に室内熱交換器で生成されるドレン水を掻き上げ手段によって掻き上げて外気吸込み口に対向する室外熱交換器の延設部から導入される外気とを混合させ室外熱交換器に飛散させて蒸発処理する。
【０００９】
さらに、本発明の空気調和機は上述の目的を満足するためになされていて、エレベータ装置を構成するゴンドラの天井部に載設される筐体からなる空気調和機本体と、この空気調和機本体内に仕切り手段を介して設けられる室内側ユニット部および室外側ユニット部とを具備し、室内側ユニット部は、ゴンドラ内に連通する室内吸込み口および室内吹出し口と、室内吸込み口から吸込まれたゴンドラ内の空気と熱交換しドレン水を受けるドレンパン上に立位する室内熱交換器と、室内吸込み口から室内空気を吸込んで室内熱交換器に導き熱交換した空気を室内吹出し口からゴンドラ内へ送風する室内送風機とを備え、室外側ユニット部は、空気調和機本体の側面板に設けられる外気吸込み口および背面板に設けられる吹出し口と、空気調和機本体内部に背面板と所定の空間を存して長手方向のほぼ中央部に背面板と略平行な略方向な幅方向に亘って配置され所定間隙を存して並置される複数枚のフィンに熱交換パイプを貫通させたいわゆるフィンドチューブタイプであり、少なくとも一方端側は所定曲率で曲成する曲成部が設けられるとともに、各曲成部から側面板に沿って直状に延出し外気吸込み口に対向する延設部が連設される室外熱交換器と、この室外熱交換器と背面板との空間に配置され外気吸込み口から吸込んだ外気を室外熱交換器を介して吹出し口から外部へ吹出す室外送風機と、この室外送風機とは室外熱交換器を介して反対側の部位に回転にともなってドレンパンから導いたドレン水を遠心方向に掻き上げる掻き上げ用円板を備え、この掻き上げ用円板の遠心方向が室外熱交換器の曲成部と対向するよう配置される複数の掻き上げ手段とを具備し、複数の掻き上げ手段におけるそれぞれの掻き上げ用円板は駆動モータの回転軸に取付けられ室外熱交換器の平面視における中心に対して所定方向に位置をずらして配置され、かつ制御装置によって室外送風機の運転と停止に同期して運転と停止するよう制御され、冷房運転時に室内熱交換器で生成されるドレン水を掻き上げ手段によって掻き上げて外気吸込み口に対向する室外熱交換器の延設部から導入される外気とを混合させ室外熱交換器に飛散させて蒸発処理する。
【００１４】
このような構成を採用することにより、室外送風機の吸込み側に室外熱交換器を位置させて騒音の低減と風量の増大が得られ、ドレン水を室外送風機のファンに当てることなく室外熱交換器に対して広域にかつ均一に散布でき、効率のよいドレン水蒸散性能を得られる。
【００１５】
【発明の実施の形態】
以下、本発明の実施の形態を、図面にもとづいて詳細に説明する。
図１は、エレベータ装置を構成するゴンドラ（以下、単にエレベータと言う）Ａと、このエレベータの天井部ａに載設される空気調和機Ｓの斜視図である。
【００１６】
上記エレベータＡは、図の手前側である前面に開閉扉ｂが設けられ、内部に乗員が出入りできる。上記空気調和機Ｓとは別の天井部位にワイヤｃが接続され、エレベータＡはワイヤｃによって吊持される。
【００１７】
この上方部には巻き上げ機が配置され、一端にエレベータＡを吊持するワイヤａが巻き付けられる。また、ワイヤａの他端にはガイドレールに沿って移動するウエイトが取付けられ、エレベータとバランスをとって昇降駆動される。（以上、図示しない）
上記空気調和機Ｓは、図２および図３に示すように構成されていて、図２は空気調和機の平面図であり、図３は空気調和機の断面図である。
空気調和機本体１は、長手（縦）方向と幅（横）方向および高さ方向ともに、矩形状に形成される筐体である。この本体１内の長手方向の中央部から側方へある程度ずれた位置には、幅方向に亘って仕切り板２（本体内仕切り手段）が設けられ、内部を左右に二分している。仕切られた一方を室内側ユニット部３Ａと呼び、他方を室外側ユニット部３Ｂと呼ぶ。
【００１８】
はじめに、上記室内側ユニット部３Ａから詳述する。
本体底面板１ａの隅部に室内吸込み口４が設けられ、これとは幅方向に離間した位置に室内吹出し口５が設けられる。これら室内吸込み口４と室内吹出し口５に対してエレベータＡの天井部ａに同一形状の開口部が設けられていて、互いに図示しないダクトが接続され、室内側ユニット部３ＡとエレベータＡ内部とが連通状態にある。
【００１９】
室内吸込み口４と室内吹出し口５との間で、かつ本体長手方向に亘って室内熱交換器６が配置される。この室内熱交換器６の下部にはドレンパンＰが配置されていて、室内熱交換器はドレンパン上に立位する。
【００２０】
上記ドレンパンＰは室内熱交換器６の底面部全体を収容するとともに、上記仕切り板２の下端部に設けられる図示しない切欠部を介して室外側ユニット部３Ｂへ延出され、このユニット部において後述するように構成される。
【００２１】
上記室内熱交換器６と本体側面板１ｂとの空間に、ファン７ｆの周面一部を上記室内吹出し口５に対向し、モータ７ｍの回転軸を室内熱交換器と対向させた室内送風機７が配置されている。このファン７ｆは、いわゆるシロッコファンと呼ばれていて、回転駆動することにより回転軸側から空気を吸込んで周面から吹出す。
【００２２】
室内吸込み口４と長手方向に並んだ位置に圧縮機８が配置され、周囲は補助仕切り板９によって囲まれる。この補助仕切り板９を備えることによって、圧縮機８から室内吸込み口４と室内熱交換器６とに対する熱的影響が阻止され、かつ騒音の漏れが防止される。
【００２３】
つぎに、上記室外側ユニット部３Ｂについて詳述する。
空気調和機本体１の両側面板１ｂ，１ｃにそれぞれ外気吸込み口１０ａ，１０ｂ，１０ｃが設けられる。後述する理由から、一方の側面板１ｃに設けられる外気吸込み口１０ａは一ヶ所であるが、他方の側面板１ｂに設けられる外気吸込み口１０ｂ，１０ｃは二ヶ所となっている。
【００２４】
本体１の背面板１ｄには吹出し口１１が設けられる。図１に示すエレベータＡを基準にしてみると、この開閉扉ｂが設けられる面と空気調和機本体１の同一面に背面板１ｄが設けられ、吹出し口１１が開口する。なお、エレベータＡに対する本体の配置方向は図１に限定されるものではなく、エレベータの設計事情に応じて適宜変更可能である。
【００２５】
本体１内において、本体背面板１ｄと所定の空間を存して長手方向のほぼ中央部に、背面板１ｄとほぼ平行な幅方向に亘って室外熱交換器１２が配置される。この室外熱交換器１２は、多数枚のフィンを互いに所定の間隙を存して並置し、これらフィンに熱交換パイプを貫通させた、いわゆるフィンドチューブタイプの熱交換器である。
【００２６】
ここでは、前後２列の熱交換器列１２Ａ，１２Ｂが並べられて室外熱交換器１２が構成される。各熱交換器列１２Ａ，１２Ｂの大部分は背面板１ｄと略平行に幅方向に亘って直状に形成され、互いに密に接触している。
【００２７】
各熱交換器列１２Ａ，１２Ｂの一方端側には所定の曲率で曲成される曲成部１２Ａ_１，１２Ｂ_１と、側面板１ｂに沿う直状の延設部１２Ａ_２，１２Ｂ_２が、それぞれ連設される。各熱交換器列１２Ａ，１２Ｂの曲成部１２Ａ_１，１２Ｂ_１の曲成方向は互いに反対方向であり、延設部１２Ａ_２，１２Ｂ_２の延出方向も互いに反対方向である。
【００２８】
したがって、前列の熱交換器列１２Ａは前面側に曲成してから側面板１ｂに沿って前面側へ延出され、後列の熱交換器列１２Ｂは背面側に曲成してから側面板１ｂに沿って背面側へ延出される。各延設部１２Ａ_２，１２Ｂ_２が沿う側面板１ｂの対向部位に、合計二ヶ所の上記外気吸込み口１０ｂ，１０ｃが設けられている。
【００２９】
各熱交換器列１２Ａ，１２Ｂの他方端側は直状のままで終わっているところから、この端部と対向する側面板１ｃには一ヶ所の外気吸込み口１０ａしか設けられていない。当然、一方端側のように曲成部と延設部とを連設してもよく、この場合は側面板に二ヶ所の外気吸込み口を設けることになる。
【００３０】
本体１内における室外熱交換器１２と背面板１ｄとの空間には、室外送風機１３が配置される。この室外送風機１３は、回転軸を背面板１ｄに対向させたファンモータ１３ｍと、このファンモータの回転軸に嵌着されるいわゆるプロペラ型のファン１３ｆからなる。
【００３１】
上記室外送風機１３のファン１３ｆと対向する本体背面板１ｄには、上記吹出し口１１が設けられる。室外送風機１３を駆動することにより、各側面板１ｂ，１ｃの外気吸込み口１０ａ，１０ｂ，１０ｃから室外側ユニット部３Ｂに外気が吸込まれて室外熱交換器１２に導かれる。そして、室外熱交換器１２から室外送風機１３を介して背面板１ｄの吹出し口１１から外部へ吹出されるようになっている。
【００３２】
上記室外送風機１３とは室外熱交換器１２を介して反対側の部位である、特に外気吸込み口１０ｂと室外熱交換器１２との間に、第１，第２の掻き上げ部材（掻き上げ手段）１５Ａ，１５Ｂが、それぞれ室外熱交換器１２と対向して並置されている。
【００３３】
第１，第２の掻き上げ部材１５Ａ，１５Ｂは、室外送風機１３のファンモータ１３ｍよりも小型のモータ１６と、このモータの回転軸に嵌着される掻き上げ用円板１７とから構成される。
【００３４】
上記室内側ユニット部３Ａに配置されるドレンパンＰは、仕切り板２を介して室外側ユニット部３Ｂへ延出され、上記掻き上げ部材１５Ａ，１５Ｂの掻き上げ用円板１７一部を囲む補助ドレンパンＰａと連通している。
【００３５】
それぞれの掻き上げ用円板１７の周縁一部が補助ドレンパンＰａに集溜するドレン水に浸漬している。この掻き上げ用円板１７が回転駆動されることによって、周縁の掻き上げ部が順次ドレン水中に浸漬し、かつ回転にともなって一点鎖線Ｅａで示す遠心方向にドレン水を掻き上げるようになっている。
【００３６】
特に図２で示すように、第１，第２の掻き上げ部材１５Ａ，１５Ｂは室外熱交換器１２の平面視上の中心よりも所定方向、ここでは側面板１ｂ方向に位置をずらせて並置される。
【００３７】
すなわち、第１，第２の掻き上げ部材１５Ａ，１５Ｂの掻き上げ用円板１７は背面板１ｄ側から見て時計回り方向に回転駆動されるようになっていて、そのため掻き上げたドレン水のより多くが側面板１ｂから側面板１ｃ方向へ跳ね飛ばされる。
【００３８】
したがって、第１，第２の掻き上げ部材１５Ａ，１５Ｂを室外熱交換器１２の平面視上の中心よりも側面板１ｂ方向に位置をずらせて配置することにより、室外熱交換器の長手方向に対してほぼ均一にドレン水を散布することとなる。
【００３９】
直接、側面板１ｃ方向へ飛散するドレン水は、その直前に配置されたストッパ兼ガイド板１９によって受け止められ、外気吸込み口１０ａから外部へドレン水が飛び出すのを防止でき、かつ吸込まれた外気は室外熱交換器１２へ確実に案内されるようになっている。
【００４０】
これら第１，第２の掻き上げ部材１５Ａ，１５Ｂのそれぞれ駆動モータ１６と、室外送風機１３のファンモータ１３ｍおよび上記圧縮機８などの電動部品の全ては、制御装置Ｔに電気的に接続されて所定の制御がなされる。
【００４１】
具体的には、第１，第２の掻き上げ部材１５Ａ，１５Ｂのそれぞれ駆動モータ１６は、制御装置Ｔによって互いに独立して運転するよう制御される。したがって、第１の掻き上げ部材１５Ａの駆動モータ１６のみ運転して、第２の掻き上げ部材１５Ｂの駆動モータ１６を停止することがあり、その逆もある。同時に運転し、もしくは停止するよう制御することもある。
【００４２】
あるいは、第１，第２の掻き上げ部材１５Ａ，１５Ｂのそれぞれ駆動モータ１６と、室外送風機１３のファンモータ１３ｍは、制御装置Ｔによって同期して運転と停止するよう制御されるようになっている。
【００４３】
特に図３に示すように、空気調和機本体１の天板１ｅは室内側ユニット部３Ａで高く、室外側ユニット部３Ｂでそれよりも低く、室外側ユニット部３Ｂにおける掻き上げ部材１５Ａ，１５Ｂの直上方部位は、仕切り板２側から室外熱交換器１２側へかけて下方に傾斜する傾斜部１ｅ_１となっている。
【００４４】
傾斜部１ｅ_１の下方には、所定間隔を存して並行に案内部材１８が取付けられる。この案内部材１８の一側端は仕切り板２とは離間し、他側端は室外熱交換器１２の上端部に接触している。掻き上げ用円板１７の遠心方向と対向する部位には開口部１８ａが設けられていて、この円板が掻き上げたドレン水が通過して天板傾斜部１ｅ_１に付着し易いようになっている。
【００４５】
このようにして構成される空気調和機であり、冷房運転を指示することにより、室内送風機７が駆動されてエレベータＡ内の空気が室内吸込み口４から本体１の室内側ユニット部３Ａに吸込まれ、室内熱交換器６に導かれて熱交換をなし、冷気に変わって室内吹出し口５から吹出される。このようにしてエレベータＡ内に冷気が供給され、室内の冷房をなす。
【００４６】
暖房運転を指示することにより、室内送風機７が駆動されてエレベータＡ内の空気が室内吸込み口４から本体の室内側ユニット部３Ａに吸込まれ、室内熱交換器６に導かれて熱交換をなし、暖気に変わって室内吹出し口５から吹出される。このようにしてエレベータＡ内に暖気が供給され、室内の暖房をなす。
【００４７】
冷暖房いずれの運転においても、室外側ユニット部３Ｂにおいては、室外送風機１３が駆動され、両側面板１ｂ，１ｃの外気吸込み口１０ａ，１０ｂ，１０ｃから外気が室外側ユニット部に吸込まれ、室外熱交換器１２に導かれて熱交換をなし、背面板１ｄの吹出し口１１から外部へ吹出される。
【００４８】
上記第１，第２の掻き上げ部材１５Ａ，１５Ｂは、冷房運転時にのみ作用する。すなわち、室内熱交換器６と熱交換した空気に含まれる水分が凝縮してドレン水に変りドレンパンＰに流下する。このドレン水は室外側ユニット部３Ｂの補助ドレンパンＰａへ流れて、各掻き上げ部材１５Ａ，１５Ｂの掻き上げ用円板１７周縁一部を浸漬する。
【００４９】
制御装置Ｔの制御にもとづいて各掻き上げ用円板１７は回転駆動されドレン水を遠心方向に掻き上げるので、ドレン水は水滴もしくは霧状になって飛散する。その一方で、室外送風機１３が駆動されて外気吸込み口１０ａ，１０ｂ，１０ｃから室外熱交換器１２へ外気を導く。この外気に水滴もしくは霧状になったドレン水が混合して、室外熱交換器１２に降りかかる。
【００５０】
冷房時には室外熱交換器１２で冷媒を凝縮して凝縮熱を放出するので、降りかかったドレン水は凝縮熱を吸収して早急に蒸発する。したがって、ドレン水は早急に蒸発処理され、かつ室外熱交換器１２の熱交換効率が向上する。
【００５１】
そして、室外送風機１３を背面側に配置し、この送風機の風下側である吸込み側に室外熱交換器１２を配置したから、室外熱交換器の表面に風圧がかからずにすみ、スムーズな風の流れを得られ、風量の増大が得られる。
【００５２】
第１，第２の掻き上げ部材１５Ａ，１５Ｂを室外熱交換器１２の風上側で、吸込まれる外気の送風路中に位置するようにしたから、風の流れが均一となって掻き上げたドレン水を均等に飛散させられる。
【００５３】
第１，第２の掻き上げ部材１５Ａ，１５Ｂを室外熱交換器１２の平面視中心に対して所定方向に位置をずらせて配置した。すなわち、掻き上げ用円板１７の回転方向により掻き上げたドレン水の飛び出し方向や飛び出し角度が変るので、この回転方向に適応する配置レイアウトとすることで、室外熱交換器全域に対して均一にドレン水を散布できる。
【００５４】
このようにして、ドレン水を室外熱交換器１２へ効率よく降りかけられ、室外熱交換器の熱交換効率をさらに高めることができ、ドレン水の蒸散効率が向上する。
【００５５】
空気の流れが静かであって運転音とドレン水掻き上げ音が小さくなり、室外熱交換器１２における風切り音が少なく、ドレン水滴が叩きつけられずにすむので、空気調和機の近傍にいても運転音が気にならない。
【００５６】
すなわち、エレベータＡの天井部ａに空気調和機本体１を配置して、エレベータＡ内の搭乗者から空気調和機本体１までの距離が非常に近い条件であるが、運転騒音を小さく抑えられ、騒音による快適性を損なわずに空調された室内空間を得ることができる。
【００５７】
特に、制御装置Ｔは第１，第２の掻き上げ部材１５Ａ，１５Ｂを、互いに独立して運転制御することから、たとえいずれか一方の掻き上げ部材の駆動モータ１６が故障しても、他方の掻き上げ部材の駆動モータの運転を継続できる。常に、ある程度のドレン水蒸散性能が確保でき、またドレン水位の変動に対応し安定して作用をなす高い性能が得られる。
【００５８】
また、制御装置Ｔは第１，第２の掻き上げ部材１５Ａ，１５Ｂのモータ１６と、室外送風機１３のファンモータ１３ｍとを、互いに同期して運転と停止するよう制御することから、室外送風機の運転停止中に掻き上げ部材がドレン水を掻き上げるような不具合の発生がない。
【００５９】
上述の実施の形態では、掻き上げ部材１５Ａ，１５Ｂを室外熱交換器１２の中心に対して所定方向に位置をずらせて配置したが、これに加えて／あるいはまた、図４および図５に模式的に示すような構成を採用してもよい。
【００６０】
はじめに、図４の掻き上げ部材１５Ａ，１５Ｂから説明すると、互いに高さ位置が相違していて、ここでは第１の掻き上げ部材１５Ａが第２の掻き上げ部材１５Ｂよりも所定寸法Ｈａだけ高く配置される。
【００６１】
すなわち、掻き上げ用円板１７のドレン水散布量は水位によって変化するため、上述のように設置高さを変えることにより、水位的に低い方（第２の掻き上げ部材１５Ｂ）の散布量が減少しても、高い方（第１の掻き上げ部材１５Ａ）の散布量が確保されるために、たとえドレン水の水位が変化しても散布域が大きく変化することはない。
【００６２】
図５の掻き上げ部材１５Ａ，１５Ｂは、掻き上げ用円板１７の上端が室外熱交換器１２に近くなるよう駆動モータ１６を傾斜して取付けてなり、先に説明したように、駆動モータ１６の中心軸を室外熱交換器１２の側面に対して直角の方向に取付ける構成とは相違する。
【００６３】
すなわち、駆動モータ１６の中心軸を室外熱交換器１２の側面に対して直角の方向に取付けると、掻き上げ用円板１７が室外熱交換器側面と平行となって、ドレン水を室外熱交換器側面と平行に掻き上げることとなるが、この円板の上端を室外熱交換器１２に近くなるよう傾けることにより、より多くのドレン水を掻き上げて室外熱交換器に散布でき、ドレン水供給量の増大化を得られる。
【００６４】
なお、上述の実施の形態では、２組の掻き上げ部材１５Ａ，１５Ｂを備えたが、これに限定されるものではなく、複数の掻き上げ部材を備えることで、本発明の目的を満足できる。
【００６６】
【発明の効果】
以上説明したように本発明によれば、一体形でドレン水を室外熱交換器へ飛散させて蒸発処理する空気調和機であり、風切り音等の騒音の低減を得るとともにドレン水蒸散効率向上化と、室外熱交換器の熱交換性能向上化を得られるなどの効果を奏する。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in the treatment structure of drain water generated in an indoor heat exchanger during cooling operation in a so-called integrated air conditioner that houses an indoor heat exchanger and an outdoor heat exchanger in a main body.
[0002]
[Prior art]
For example, an air conditioner that cools or heats the interior of an elevator is mounted on a gondola (hereinafter simply referred to as an elevator) that constitutes the elevator apparatus. As this air conditioner, a so-called integrated type using a refrigeration cycle and having an indoor heat exchanger and an outdoor heat exchanger in the main body is used.
[0003]
During the cooling operation, the dew point of the air that is heat-exchanged by the indoor heat exchanger is lowered, moisture is condensed, and it is dripped as drain water. A drain pan is disposed under the heat exchanger, and all drain water is collected. Drain water is guided to the outdoor heat exchanger side and sprinkled up. By spraying water on the heat exchanger, heat exchange efficiency is improved and drain water is evaporated.
[0004]
Specifically, drain water is pumped up by a drain pump and dripped from the upper end of the outdoor heat exchanger. Alternatively, a slinger ring is attached along the outer peripheral end of the propeller fan constituting the outdoor blower, and the outside air is blown to the outdoor heat exchanger by the fan, and the slinger ring scoops up the drain water and falls down to the outdoor heat exchanger.
[0005]
[Problems to be solved by the invention]
However, in the drain water pumping method using the drain pump, the drain water cannot be uniformly sprayed to the outdoor heat exchanger having a slight size in the width direction and an extremely long length in the plan view. Low water transpiration performance. Conventionally, uniform dispersion using a highly hydrophilic nonwoven fabric or the like is performed, but problems such as clogging with dust are likely to occur.
[0006]
Further, in the slingering method, the propeller fan has a relatively large diameter, and the sound when the slingering scoops up the drain water is loud. Since outdoor air and drain water are blown against the outdoor heat exchanger, the wind noise from the outdoor heat exchanger overlaps with the sound of the drain water being struck against the outdoor heat exchanger, resulting in loud noise and an outdoor heat exchanger. It is a factor of performance deterioration.

[0021]
In the space between the indoor heat exchanger 6 and the main body side plate 1b, an indoor blower 7 in which a part of the peripheral surface of the fan 7f is opposed to the indoor outlet 5 and the rotation shaft of the motor 7m is opposed to the indoor heat exchanger. Is arranged. The fan 7f is called a so-called sirocco fan, and is driven to rotate to suck air from the rotating shaft side and blow it out from the peripheral surface.
[0022]
A compressor 8 is arranged at a position aligned with the indoor suction port 4 in the longitudinal direction, and the periphery is surrounded by an auxiliary partition plate 9. By providing this auxiliary partition plate 9, the thermal influence from the compressor 8 to the indoor suction port 4 and the indoor heat exchanger 6 is blocked, and noise leakage is prevented.
[0023]
Next, the outdoor unit 3B will be described in detail.
Outside air suction ports 10a, 10b, and 10c are provided on both side plates 1b and 1c of the air conditioner main body 1, respectively. For reasons that will be described later, the outside air suction port 10a provided in one side plate 1c is provided in one place, but the outside air suction ports 10b and 10c provided in the other side plate 1b are provided in two places.
[0024]
A blowout port 11 is provided on the back plate 1 d of the main body 1. When the elevator A shown in FIG. 1 is taken as a reference, a back plate 1d is provided on the same surface of the air conditioner main body 1 as the surface on which the door b is provided, and the outlet 11 is opened. In addition, the arrangement | positioning direction of the main body with respect to the elevator A is not limited to FIG. 1, It can change suitably according to the design situation of an elevator.
[0025]
In the main body 1, an outdoor heat exchanger 12 is disposed in a substantially central portion in the longitudinal direction with a predetermined space with the main body back plate 1 d over a width direction substantially parallel to the back plate 1 d. The outdoor heat exchanger 12 is a so-called finned tube type heat exchanger in which a large number of fins are juxtaposed with each other with a predetermined gap therebetween and a heat exchange pipe is passed through the fins.
[0026]
Here, the outdoor heat exchanger 12 is configured by arranging two heat exchanger rows 12A and 12B in the front and rear rows. Most of each of the heat exchanger rows 12A, 12B is formed in a straight shape over the width direction substantially parallel to the back plate 1d, and is in close contact with each other.
[0027]
On one end side of each of the heat exchanger rows 12A and 12B, bent portions 12A ₁ and 12B ₁ that are bent with a predetermined curvature, and straight extending portions 12A ₂ and 12B ₂ along the side plate 1b, Each one is connected. The bending directions of the bent portions 12A ₁ and 12B ₁ of the heat exchanger rows 12A and 12B are opposite to each other, and the extending directions of the extending portions 12A ₂ and 12B ₂ are also opposite to each other.
[0028]
Accordingly, the front heat exchanger row 12A is bent to the front side and then extended to the front side along the side plate 1b, and the rear heat exchanger row 12B is bent to the rear side and then the side plate 1b. Is extended to the back side. A total of two outside air inlets 10b and 10c are provided at opposing portions of the side plate 1b along which the extending portions 12A ₂ and 12B ₂ extend.
[0029]
Since the other end side of each heat exchanger row 12A, 12B ends in a straight shape, the side plate 1c facing this end portion is provided with only one outside air inlet 10a. Naturally, the bent portion and the extended portion may be provided continuously on one end side. In this case, two side air inlets are provided on the side plate.
[0030]
An outdoor fan 13 is disposed in the space between the outdoor heat exchanger 12 and the back plate 1d in the main body 1. The outdoor blower 13 includes a fan motor 13m having a rotation shaft opposed to the back plate 1d, and a so-called propeller type fan 13f fitted on the rotation shaft of the fan motor.
[0031]
The blowout port 11 is provided in the main body back plate 1 d facing the fan 13 f of the outdoor blower 13. By driving the outdoor blower 13, the outside air is sucked into the outdoor unit 3B from the outside air inlets 10a, 10b, 10c of the side plates 1b, 1c, and led to the outdoor heat exchanger 12. And it blows off from the blower outlet 11 of the backplate 1d through the outdoor air blower 13 from the outdoor heat exchanger 12.
[0032]
The outdoor blower 13 is a part opposite to the outdoor heat exchanger 12, and in particular, between the outdoor air inlet 10 b and the outdoor heat exchanger 12, the first and second scraping members (scraping means) ) 15A and 15B are juxtaposed facing the outdoor heat exchanger 12, respectively.
[0033]
The first and second scraping members 15A and 15B are composed of a motor 16 that is smaller than the fan motor 13m of the outdoor blower 13 and a scraping disc 17 that is fitted to the rotating shaft of the motor. .
[0034]
The drain pan P disposed in the indoor unit 3A extends to the outdoor unit 3B via the partition plate 2 and surrounds a part of the scraping disk 17 of the scraping members 15A and 15B. It communicates with Pa.
[0035]
A part of the periphery of each scraping disc 17 is immersed in the drain water collected in the auxiliary drain pan Pa. The scraping disc 17 is driven to rotate, so that the peripheral scraping portion is sequentially immersed in the drain water, and the drain water is scraped up in the centrifugal direction indicated by the alternate long and short dash line Ea along with the rotation. Yes.
[0036]
In particular, as shown in FIG. 2, the first and second scooping members 15A and 15B are juxtaposed in a predetermined direction relative to the center of the outdoor heat exchanger 12 in plan view, in this case, in the direction of the side plate 1b. The
[0037]
That is, the scooping disc 17 of the first and second scooping members 15A and 15B is rotationally driven in the clockwise direction when viewed from the back plate 1d side. More is splashed from the side plate 1b toward the side plate 1c.
[0038]
Therefore, the first and second scraping members 15A and 15B are arranged in a position shifted in the direction of the side plate 1b from the center of the outdoor heat exchanger 12 in a plan view, so that the longitudinal direction of the outdoor heat exchanger is increased. On the other hand, drain water is sprayed almost uniformly.
[0039]
The drain water that directly scatters in the direction of the side plate 1c is received by the stopper / guide plate 19 disposed immediately before the drain water, and the drain water can be prevented from jumping out from the outside air suction port 10a. It is surely guided to the outdoor heat exchanger 12.
[0040]
The drive motor 16 of each of the first and second scraping members 15A, 15B, the fan motor 13m of the outdoor blower 13, and the electric parts such as the compressor 8 are all electrically connected to the control device T. Predetermined control is performed.
[0041]
Specifically, the drive motors 16 of the first and second scraping members 15A and 15B are controlled to operate independently from each other by the control device T. Accordingly, only the drive motor 16 of the first scraping member 15A may be operated and the drive motor 16 of the second scraping member 15B may be stopped, and vice versa. It may be controlled to operate or stop at the same time.
[0042]
Alternatively, the drive motor 16 of each of the first and second scraping members 15A and 15B and the fan motor 13m of the outdoor blower 13 are controlled by the control device T so as to be stopped and operated in synchronization. .
[0043]
In particular, as shown in FIG. 3, the top plate 1e of the air conditioner main body 1 is higher in the indoor unit 3A, lower than it in the outdoor unit 3B, and the scraping members 15A and 15B in the outdoor unit 3B . The portion directly above is an inclined portion 1e ₁ that is inclined downward from the partition plate 2 side to the outdoor heat exchanger 12 side.
[0044]
Below the inclined portion 1e ₁ , a guide member 18 is attached in parallel at a predetermined interval. One end of the guide member 18 is separated from the partition plate 2, and the other end is in contact with the upper end of the outdoor heat exchanger 12. The portion facing the centrifugal direction of scraping up for disc 17 have openings 18a is provided, so easily attached to the top plate inclined portion 1e ₁ drain water this disc is raised scraped passes through ing.
[0045]
The air conditioner is configured as described above, and when the cooling operation is instructed, the indoor blower 7 is driven and the air in the elevator A is sucked into the indoor unit 3A of the main body 1 from the indoor suction port 4. Then, the heat is guided to the indoor heat exchanger 6 to be exchanged, and the air is changed into cold air and blown out from the indoor outlet 5. In this way, cool air is supplied into the elevator A to cool the room.
[0046]
By instructing the heating operation, the indoor blower 7 is driven and the air in the elevator A is sucked into the indoor unit 3A of the main body from the indoor suction port 4 and led to the indoor heat exchanger 6 for heat exchange. Then, it changes into warm air and is blown out from the indoor outlet 5. In this way, warm air is supplied into the elevator A to heat the room.
[0047]
In both the cooling and heating operations, the outdoor blower 13 is driven in the outdoor unit 3B, and the outdoor air is sucked into the outdoor unit through the outdoor air inlets 10a, 10b, and 10c of the side plates 1b and 1c, and the outdoor heat exchange is performed. The heat is exchanged by being guided to the vessel 12 and blown out from the blow-out port 11 of the back plate 1d.
[0048]
The first and second scraping members 15A and 15B act only during the cooling operation. That is, the moisture contained in the air exchanged with the indoor heat exchanger 6 is condensed and turned into drain water and flows down to the drain pan P. The drain water flows into the auxiliary drain pan Pa of the outdoor unit 3B, and immerses a part of the periphery of the scraping disk 17 of the scraping members 15A and 15B.
[0049]
Under the control of the control device T, each of the scooping discs 17 is rotationally driven to scoop up the drain water in the centrifugal direction, so that the drain water scatters in the form of water droplets or mist. On the other hand, the outdoor blower 13 is driven to guide the outside air from the outside air inlets 10a, 10b, and 10c to the outdoor heat exchanger 12. The outside air is mixed with water droplets or mist-like drain water and falls onto the outdoor heat exchanger 12.
[0050]
During cooling, the outdoor heat exchanger 12 condenses the refrigerant and releases the condensation heat, so that the drained water that has fallen absorbs the condensation heat and evaporates quickly. Therefore, the drain water is immediately evaporated and the heat exchange efficiency of the outdoor heat exchanger 12 is improved.
[0051]
And since the outdoor air blower 13 is arranged on the back side and the outdoor heat exchanger 12 is arranged on the suction side which is the leeward side of this air blower, wind pressure is not applied to the surface of the outdoor heat exchanger, and smooth air The flow of air can be obtained, and an increase in the air volume can be obtained.
[0052]
Since the first and second scooping members 15A and 15B are positioned on the windward side of the outdoor heat exchanger 12 and in the air blowing path of the sucked outside air, the air flow is uniformed and swept up. Drain water can be evenly scattered.
[0053]
The first and second scraping members 15 </ b> A and 15 </ b> B are arranged with their positions shifted in a predetermined direction with respect to the plan view center of the outdoor heat exchanger 12. That is, the direction and angle of drain water drained up depending on the direction of rotation of the scooping disc 17 changes, and by adopting an arrangement layout that adapts to this direction of rotation, the entire area of the outdoor heat exchanger can be made uniform. Can drain water.
[0054]
In this way, the drain water can be efficiently dropped onto the outdoor heat exchanger 12, the heat exchange efficiency of the outdoor heat exchanger can be further increased, and the drainage transpiration efficiency is improved.
[0055]
Since the air flow is quiet, the operation noise and drain water pick-up sound are reduced, the wind noise in the outdoor heat exchanger 12 is small, and the drain water droplets are not struck, so the operation sound is close to the air conditioner. I do n’t care.
[0056]
That is, the air conditioner main body 1 is arranged on the ceiling portion a of the elevator A, and the distance from the passenger in the elevator A to the air conditioner main body 1 is a very close condition, but the driving noise can be kept small, An air-conditioned room space can be obtained without impairing comfort due to noise.
[0057]
In particular, since the control device T controls the operation of the first and second scraping members 15A and 15B independently of each other, even if the drive motor 16 of one of the scraping members fails, the other The operation of the drive motor of the scraping member can be continued. A certain degree of drain water transpiration performance can be secured at all times, and a high performance can be obtained that stably operates in response to fluctuations in the drain water level.
[0058]
Further, since the control device T controls the motor 16 of the first and second scraping members 15A and 15B and the fan motor 13m of the outdoor blower 13 to synchronize with each other and stop the operation, There is no problem that the scraping member scoops up the drain water while the operation is stopped.
[0059]
In the above-described embodiment, the scraping members 15A and 15B are arranged with their positions shifted in a predetermined direction with respect to the center of the outdoor heat exchanger 12, but in addition to / or alternatively, schematically shown in FIGS. A configuration as shown in FIG.
[0060]
First, the scraping members 15A and 15B in FIG. 4 will be described. The height positions are different from each other. Here, the first scraping member 15A is disposed higher than the second scraping member 15B by a predetermined dimension Ha. Is done.
[0061]
That is, since the amount of drain water sprayed on the scooping disc 17 varies depending on the water level, the spray amount of the lower water level (second scraping member 15B) can be reduced by changing the installation height as described above. Even if it decreases, the spraying amount of the higher one (first scraping member 15A) is secured, so even if the drain water level changes, the spraying area does not change greatly.
[0062]
The scraping members 15A and 15B in FIG. 5 are formed by attaching the drive motor 16 so that the upper end of the scraping disc 17 is close to the outdoor heat exchanger 12, and as described above, the drive motor 16 Is different from the configuration in which the central axis is attached in a direction perpendicular to the side surface of the outdoor heat exchanger 12.
[0063]
That is, when the central axis of the drive motor 16 is attached in a direction perpendicular to the side surface of the outdoor heat exchanger 12, the scraping disc 17 is parallel to the side surface of the outdoor heat exchanger, and the drain water is exchanged with the outdoor heat. However, by tilting the upper end of the disk so as to be close to the outdoor heat exchanger 12, more drain water can be scraped up and sprayed to the outdoor heat exchanger. Increased supply can be obtained.
[0064]
In the above-described embodiment, the two sets of scooping members 15A and 15B are provided. However, the present invention is not limited to this, and the object of the present invention can be satisfied by providing a plurality of scooping members.
[0066]
【The invention's effect】
As described above, according to the present invention, it is an air conditioner that integrally evaporates drain water to an outdoor heat exchanger, and obtains reduction of noise such as wind noise and improves drain water transpiration efficiency. In addition, the heat exchange performance of the outdoor heat exchanger can be improved.
