Description

【0001】
【発明の属する技術分野】
この発明は、屋外に設置され、屋内の冷凍機凝縮器との間を循環する冷却水を冷却する冷却塔に設けられた冷却塔散水槽用カバー装置に関する。
【0002】
【従来の技術】
従来、建築物の屋上等には、屋内冷房用の冷却水等を冷却するための冷凍機の凝縮器との間を循環する冷却水を冷却する冷却塔が設けられている。一般に角形の冷却塔には、建築物に固定された支持部が設けられ、支持部に矩形の本体が取り付けられている。本体の、互いに対向する一対の側面には、細いスリット状の通気部が全面に設けられ、本体の上面中央には、本体内の空気を本体の外側に排気するファン部材が取り付けられている。本体上面の、ファン部材の両側には、上方に開口した散水槽が設けられている。散水槽は、深さが比較的浅く、底部に多数の通水口が形成され、この散水槽の下方には、図示しない貯水槽が設けられている。
【0003】
さらにこの冷却塔には、冷凍機の凝縮器部で予熱された冷却水を循環させる冷却水循環配管が設けられ、この配管に設けられたポンプにより、冷却水が散水槽に組み上げられる。ポンプ装置からの配管は、散水槽のほぼ中央に貫通して取り付けられている。散水槽と貯水槽との間には、波板状の冷却水の気化を促す気化用板が設けられている。気化用板は、縦方向に複数枚が互いに平行に設けられている。気化用板が設けられる向きは、本体側面の、通気部が設けられている側面に対して直交する方向に設けられている。
【0004】
次に、冷却塔の動作作用について説明する。散水槽にくみ上げられた冷却水は通水口から落下し、気化用板表面を伝って貯水層にたまる。気化用板表面を伝って水が落下するとき、ファン部材により内側の空気が上方に排出され側方かの空気流が気化用板表面を通過する。そして空気流により気化用板表面の水の一部が蒸発して気化熱が奪われるとともに、冷やされた水が貯水層の底部にたまる。この冷やされた冷却水は、再び冷凍機凝縮器へ供給され循環する。
【0005】
【発明が解決しようとする課題】
上記従来の技術の場合、散水槽は上面が開口しているため、直射日光が当たり、また水温が35℃〜38℃となることから、水藻が発生しやすい。水藻が発生すると、散水槽の通水口が目詰まりして、冷却用の水流が阻害されるという問題があり、これを防ぐために定期的な掃除が必要であった。また水藻の発生を抑える薬品を冷却用の水に添加しているが、多量の薬品を必要としランニングコストがかかるものであった。
【0006】
水藻の発生を抑える方法として、光合成を抑えるために日光を遮断する方法がある。例えば、散水槽の開口部分に、蓋部材をビス等で固定するものであるが、この方法だと散水槽のメンテナンスのたびに蓋部材を取り外さなければならず面倒であり、手間がかかるものであった。また、時間の経過とともにビスにさびが発生して外しにくい上、一旦外すと再利用することができず、無駄が生じていた。また塩化ビニル製のブルーシート等をかけて簡易的に遮光する方法もあるが、シートが破損しやすく外観上も好ましくないいという問題があった。
【0007】
この発明は上記従来の問題点に鑑みてなされたものであり、簡単な構造で散水槽を遮光して水藻の発生を抑え、メンテナンスも容易に可能な冷却塔散水槽用カバー装置を提供することを目的とする。
【0008】
【課題を解決するための手段】
この発明は、空調用熱源装置の外気との熱交換装置である冷却塔に設けられている散水槽開口部に取り付けられた一対のガイド部材と、上記ガイド部材に摺動可能に取り付けられる複数枚の遮蔽板と、上記遮蔽板を並べて上記散水槽を閉鎖した状態で各遮蔽板を互いに係止する係止部材とが設けられている冷却塔散水漕用カバー装置である。
【0009】
また、上記散水槽のほぼ中央には、散水槽に水をくみ上げて散水槽に送る給水装置が設けられている。上記遮蔽板は合成樹脂で作られ、上記遮蔽板の給水装置部分に対向する端縁部には、上記給水装置の周囲に当接するように切欠部が形成されている。
【0010】
また、上記ガイド部材は互いに平行な第一ガイド溝と第二ガイド溝が設けられた枠部材から成る。上記第一ガイド溝には上記給水装置を両側から囲む一対の第一遮蔽板が摺動可能に取り付けられ、上記第二ガイド溝には上記第一遮蔽板と上記ガイド部材の端部側の開口を閉鎖する第二遮蔽板が設けられている。
【0011】
この発明の冷却塔散水漕用カバー装置は、第一遮蔽板と第二遮蔽板を枠部材内に嵌め込んで係止することにより、散水槽内を遮光し水藻の発生を防ぎ、ごみの混入を防ぐ。メンテナンスの際は、第一遮蔽板と第二遮蔽板の係止を解除し、一方をスライドさせて他方に重ねることにより、散水槽内を露出させることができる。
【0012】
【発明の実施の形態】
以下、この発明の実施の形態について図面に基づいて説明する。図1〜図3は、この発明の一実施形態を示すものであり、この実施形態の冷却塔散水槽用カバー装置10は、建築物の屋上等に設置される角形開放式の冷却塔12に取り付けられている。
【0013】
冷却塔12は、建築物に設置される支持部14が設けられ、支持部14にほぼ直方体の本体16が設置されている。本体16の、互いに対向する一対の側面16a,16bには、多数のスリットからなる通気部18が全面に設けられている。本体16の上面16cの中央には、ファン装置20が取り付けられている。ファン装置20は、本体16の内の空気を本体16の外側に排気するものである。
【0014】
本体16の上面16cの、一対の側面16a,16bと連続する端縁部付近には、上方に開口した散水槽22が各々設けられている。散水槽22は、本体16の上面16cの、側面16a,16bと連続する端縁部に沿って長細い矩形に形成されている。散水槽22は、深さが浅く底部に多数の通水口23が形成されている。散水槽22の下方には、図示しない貯水槽が設けられている。散水槽22と貯水槽の間には、冷凍機の凝縮器から送られてきた冷却水を散水槽22内にくみ上げる給水装置24が設けられている。給水装置24には、散水槽22の底部を貫通して下方の貯水槽に達するパイプ26部材が設けられ、パイプ26は図示しないポンプによってくみ上げられた水を散水槽22に供給するものである。散水槽22の底部に貫通したパイプ26の上端部には、矩形のパイプカバー28がかぶせられて設けられている。パイプカバー28は、散水槽22との間に所定の隙間を生じて固定されている。
【0015】
冷却塔12の散水槽22の下方には、波板状の冷却水冷却用の図示しない気化用板が設けられている。気化用板はほぼ垂直に設けられ、表面が水平方向に波形に形成された薄板部材である。そして、複数枚が互いに平行に、本体16の通気部18が設けられた側面16a,16bに対してほぼ直交する方向に設けられている。なお、散水槽22、パイプカバー28、気化用板等の各部材は塩化ビニル等の合成樹脂で作られている。
【0016】
また、冷却塔12には作業員が本体16を登るためのはしご30が設けられ、はしご30の下端部には、水平方向に延びる点検口ステップ32が設けられている。
【0017】
一対の散水槽22の上面開口部の周囲には、矩形の枠部材34が各々取り付けられている。枠部材34は例えばステンレス製であり、図2に示すように、内側に互いに平行に一対のガイド溝が設けられ、本体16の内部側を第一ガイド溝36、本体16の外部側を第二ガイド溝38とする。第一ガイド溝36と第二ガイド溝38は、枠部材34の短辺側にも連続して形成されている。
【0018】
第一ガイド溝36には、枠部材34の長手方向の各端部34a,34bと給水装置24のパイプカバー28までの距離の半分以上を覆う一対の第一遮蔽板40が摺動可能に設けられている。第二ガイド溝38には、第一遮蔽板40と枠部材34の長手方向の端部34a,34bとの間に生じる隙間を覆う一対の第二遮蔽板42が、摺動可能に設けられている。これにより散水槽22には、一対の第一遮蔽板40と一対の第二遮蔽板42の、計4枚が設けられている。第一遮蔽板40と第二遮蔽板42は、塩化ビニル等の合成樹脂製である。
【0019】
第一遮蔽板40には、パイプカバー28側の端縁部40aに、パイプカバー28の約半分に嵌合する切欠部44が形成されている。切欠部44の近傍には、第一遮蔽板40表面に突出する棒状の操作部46が設けられている。第一遮蔽板40の、端縁部40aと反対の端縁部40b付近には、後述する係止部材52が挿通される透孔48が形成されている。
【0020】
第二遮蔽板42は、第一遮蔽板40の端縁部40bの外側に重ねられる端縁部42a付近に、第一遮蔽板40の透孔48に連通する透孔50が形成されている。透孔50には、第一遮蔽板40の透孔48に連通した状態で、棒状の係止部材52が挿通され、第一遮蔽板40と第二遮蔽板42を係止している。第二遮蔽板42の、端縁部42aと反対側の端縁部42b付近には、第二遮蔽板42表面に突出する棒状の操作部54が形成されている。
【0021】
次にこの実施形態の冷却塔散水槽用カバー装置10の使用方法について説明する。まず、冷却塔12について説明する。冷却塔12の散水槽22には、冷却水が満たされている。冷却水には、水藻や細菌の繁殖を抑える薬品が添加されている。散水層22に満たされた冷却水は、通水口23から流れ落ちる。流れ落ちた冷却水は散水槽22下方に設けられた図示しない気化用板に伝って落ち、図示しない貯水槽に落下してたまる。このとき、ファン部材20は、本体16内の空気を外側に排気している。このため、本体16の一対の側面16a,16bに形成された通気部18から空気が本体16内に流れ込み、気化用板に吹き付けながら本体16の上面16cへ流れ、ファン部材20により排気される。このとき気化用板表面を流れる冷却水の一部は蒸発し、気化熱を奪われ、貯水槽の冷却水の温度が低くなる。冷やされた冷却水は、冷凍機の凝縮器に送られ、凝縮器で熱交換され、給水装置24により再び散水槽22に送られる。
【0022】
この冷却塔散水槽用カバー装置10の使用方法は、第一遮蔽板40の透孔48と第二遮蔽板42の透孔50を連通して係止部材52を挿通する。これにより、散水層22を閉鎖し、日光を遮る。通水口23の目詰まりによるごみの除去等のメンテナンスの際は、係止部材52を引き抜いて第一遮蔽板40と第二遮蔽板42の係止を解除し、第一遮蔽板40または第二遮蔽板42を摺動させて互いに重ね、散水槽22内を露出させる。なお、第一遮蔽板40と第二遮蔽板42は、力を加えて湾曲させながら枠部材34に対して着脱可能である。
【0023】
この実施形態の冷却塔散水槽用カバー装置10によれば、簡単な構造で散水槽22に対して日光を遮り、水藻の発生を抑えることができる。水藻の発生を抑えることにより、掃除回数が減り、メンテナンスが容易となる。また、水藻の発生を抑えるための薬品の添加量を減らすことができ、ランニングコストを抑えることができる。またメンテナンスの際は、第一遮蔽板40または第二遮蔽板42をスライドさせて散水槽22の一部を露出させることができ、容易にメンテナンスが可能である。第一遮蔽板40と第二遮蔽板42の係止と解除は、係止部材52を差し込んだり引き抜いたりする簡単な操作で行うことができ、特殊な工具を必要とせず便利である。また、蝶番等のさびやすい部品を使わず、高い耐久性を有している。第一遮蔽板40と第二遮蔽板42は、時間経過とともにそりが生じる恐れがあるが、両側縁部が枠部材34に押さえられているため隙間を生じることがなく、確実に遮光することができる。
【0024】
なお、この発明の冷却塔散水槽用カバー装置は、上記実施の形態に限定されるものではなく、各部材の形状や素材等、自由に変更可能である。遮蔽板の枚数は、ひとつの散水槽22につき、4枚以外に6枚など自由に変更可能である。遮蔽板同士の係止部材は、上記実施の形態意外に、簡単で確実に係止することができるものであればよい。冷却塔の散水槽以外の用途に利用してもよい。
【0025】
【発明の効果】
この発明の冷却塔散水漕用カバー装置は、簡単な構造で確実に散水槽内を遮光し、水藻の発生を抑えることができる。また、遮蔽板は開閉自在であるため、開口して散水槽22内のメンテナンスをすることができる。また、耐久性があり長期間の使用が可能で、経済的である。
