Description

【０００１】
【発明の属する技術分野】
本発明は、放射冷暖房システムに関する。
【０００２】
【従来の技術】
従来、パネル面にチューブ等を這わせ、内部に冷水又は温水を通水し、パネル表面を所定の温度を保ち、壁体や人体と放射による熱交換を行うことによって、快適な状態を維持する放射冷暖房システムが開発されている。
【０００３】
この放射冷暖房システムの利点は、冷風や温風を供給する一般的な空調システムと異なり、放射パネルを天井全面に配設するため、室内空間の温度むらや時間による温度変化が少なく、温度設定も緩めにでき、経済効果を高められる。又、放射パネル設置場所に音源となる機器類がないため、室内に静寂が確保される。
【０００４】
このような利点を効果的に活用できる図書館や病院、老人ホームといった静かで柔らかい環境が求められる空間の空調に広く採用されており、図８に示されているように前記図書館や病院、老人ホーム等の室内０１の天井全面に放射パネル０２が隙間なく配設され、該放射パネル０２の内部には一連のチューブ０３が組み込まれている。
【０００５】
このチューブ０３には、循環ポンプ０１０の運転と所定の場所に設置されている熱交換器０８で冷房時には例えば１５℃程度に冷却された冷水が、暖房時には例えば３５℃程度に加熱された温水が挿入管０４を通して注入される。また該熱交換器０８には、熱源機器（開示せず）から例えば７℃程度の一次冷水又は例えば４０℃程度の一次温水が供給され、該チューブ０３に供給する冷水の冷却又は温水の加熱を行っている。
【０００６】
さらに、注入された冷水又は温水は放射パネル０２内の一連のチューブ０３を通過する間に室内０１と放射による熱交換を行い、室内０１温度が所定の設定温度に調整される。室内０１と放射による熱交換を行い、温まった水又は温度が低下した温水は、放出管０５を介して熱交換器０８へと送られ再び冷却、又は加熱され、各放射パネル０２のチューブ０３へと還流される。
【０００７】
室内０１の一方の天井近傍には、空気噴出ダクト０６が、他方の天井近傍には、空気排気ダクト０７が設けられており、前記空気噴出ダクト０６からは空気調和機０９によって調温調湿された空気が噴出され、換気のために必要な外気の導入と、後述するように、冷房時の放射パネル０２と室内０１との温度差により発生する放射パネル０２表面の結露の防止又は除去する目的と、暖房時の暖気が天井付近に滞留するのを防止し、室内０１の均一的な温度に保持する役目を行っている。また該空気調和機０９には前記熱源機器から例えば７℃程度の一次冷水又は例えば４０℃程度の一次温水が供給され、さらに加湿用の水又は蒸気が供給され、前記空気噴出ダクト０６に供給する空気の調温調湿を行っている。
【０００８】
一方空気排気ダクト０７は、冷房時には室内０１の湿り気のある空気を排出する目的と、暖房時には室内０１に滞留した空気の流れを促進し、気流による空気の攪拌を促すために設けられている。
【０００９】
【発明が解決しようとする課題】
しかしながら、放射冷暖房システムは、一般的な空調システムのように室内に冷風や温風を供給しての対流による熱交換でなく、放射パネル表面温度と壁体又は人体の表面温度との温度差から生じる放射及び自然対流による熱交換が主体であるため、放射パネルと室内との間に温度差を必要とする。
【００１０】
このことから、冷房時には放射パネル表面の温度を室温より低く保つ必要があるため、室内で発生する水蒸気が低温状態の放射パネル表面で凝縮し結露が発生することになる。
【００１１】
又、暖房時には、一般的な空調システムのように風力を利用して暖気の誘導を行わないために、放射パネル表面で暖められた暖気が天井付近に滞留し、室内全体を均一な温度に保持することが困難であった。
【００１２】
前述した従来の放射冷暖房システムには、上記のような結露の防止と不均一な室内温度の調整を少しでも解消する方法として、図１の空気噴出ダクト０６が設けられたが、噴出される調温調湿された空気は、室内０１の静寂さを妨げない程度に弱い風量に限られるため、空気噴出ダクト０６近傍の放射パネル０２表面に発生する結露の防止は可能なものの、空気噴出ダクト０６から遠ざかる放射パネル０２表面には調温調湿された空気が届かないため、結露が発生し、特に冷房時でのチューブ０３の冷水注入口近傍には多くの結露が発生し、最後には結露水となり床に落下し、敷物にシミができたり、結露水の溜まっている箇所にカビが発生するなどの不衛生な室内環境をもたらす原因にもなった。又、暖房時の天井付近への暖気の滞留も空気噴出ダクト０６近傍では解消できるものの、空気噴出ダクト０６近傍以外では暖気の滞留を解消できず、室内０１を均一な所定温度に保持することは困難であった。
【００１３】
本発明は、このような問題点に着目してなされたもので、冷房時の放射パネル表面での結露、及び暖房時の天井付近への暖気の滞留を防止する放射冷暖房システムを提供することを目的とする。
【００１４】
【課題を解決するための手段】
上記課題を解決するために、本発明の放射冷暖房システムは、所定の冷暖房放射パネルに間隙を設けて配設し、該間隙の所定箇所に揺動風向片を備えた空気噴出ダクトを設け、該空気噴出ダクトから空気を噴出可能にしたことを特徴としている。
この特徴によれば、放射冷暖房システムの冷房稼動時に、放射パネル隣接して設けられた間隙の所定箇所から調温調湿された空気を揺動風向片を介して噴出させることにより、噴出された該空気が放射パネル表面に満遍なく供給されるため、放射パネル表面に付着した結露粒子が蒸発し、放射パネル表面での結露の増長を防止できるとともに、結露水が床に落下し、敷物にシミができたり、結露水の溜まっている箇所にカビが発生するなどの不衛生な室内環境をも防止でき、さらに、室内に発生する適度な気流によって冷涼感（そよぎ）が増幅されるため、放射パネル表面温度を高めに設定でき、省エネを計ることができ、コストダウンが期待できる。例えば、冷房時の室温を２６℃とし、前記放射パネル表面の温度を１８℃とし、室温湿度を７０％以上にして強制的に該放射パネルに結露をさせる実験を行なったところ、該放射パネル表面に結露を生じたが、該放射パネルに隣接して設けられた前記間隙の前記所定箇所から温度２６℃、湿度５０％程度の調温調湿空気を噴出させることによって、該放射パネルに付着した結露の増長が抑えられることを確認し、また、適度な気流があることで快適性が向上することを確認した。
又、放射冷暖房システムの暖房稼動時に、放射パネルに隣接して設けられた間隙の所定箇所から調温調湿された空気を揺動風向片を介して噴出させることにより、噴出された該空気が天井付近に滞留した暖気を攪拌するとともに、室内に適度な気流が確保されるため、室内全体の均一な温度を短時間に保持することが可能になり、省エネを計ることができ、コストダウンが期待できる。例えば、暖房時の室温を２２℃とし、前記放射パネル表面の温度を３２℃として実験を行なったところ、該放射パネルに隣接して設けられた前記間隙の前記所定箇所からの調温調湿空気の噴出がない場合は、足元と頭上との間で２℃以上の温度差が生じ、足元の冷えを解消するために該パネル表面の温度を上昇させる必要が認められたが、該所定箇所から温度２２℃、湿度５０％程度の調温調湿空気を噴出させた場合は、部屋全体が２２℃の均一な状態になり、足元の冷えが存在しないことを確認した。
【００１５】
本発明の放射冷暖房システムは、前記揺動風向片は送風される風力を利用して回動可能になっていることが好ましい。
このようにすれば、送風される風力を利用しているので電気配線工事等を施す必要がなく経済性に富み、省エネを計ることができるばかりでなく、揺動風向片の稼動を周期的に変更することができるため、放射パネル表面への長時間におよぶ風量のかけ過ぎによる放射パネル表面温度の降下時に発生する再結露を防止できる。
【００１６】
本発明の放射冷暖房システムは、前記間隙の両側の冷暖房放射パネルが前記間隙に向かって下降傾斜するように形成されていることが好ましい。
このようにすれば、前記空気噴出ダクトから噴出された調温調湿空気が、放射パネル面の下降傾斜面を伝って傾斜下端部に自動的に集結した結露水を集中的に蒸発させるので、効率的に放射パネル表面の結露水の落下を防止できる。
【００１７】
本発明の放射冷暖房システムは、隣接する冷暖房放射パネルの上昇傾斜側に形成される間隙には照明器具が支持されていることが好ましい。
このようにすれば、前記間隙部に向かって上昇傾斜するように配設された冷暖房放射パネルの傾斜上端部が、照明器具の放射熱に暖められて、わずかな結露粒子の発生をも防止できる。
【００１８】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて説明すると、図１〜図７は、本発明の一実施形態を示すもので、図１は本発明の放射冷暖房システムの概略図、図２は一部を省略した図１の拡大平面図、図３は本発明に係る空気噴出ダクトの断面図、図４は本発明に係る放射冷暖房パネルの一部を破砕した平面図、図５は図４のＡ―Ａ拡大断面図、図６は本発明に係る揺動風向片駆動装置の概略図、図７は本発明の放射冷暖房システムの別の実施例を示す概略図、図８は従来の放射冷暖房システムの概略図である。
【００１９】
まず図１には本発明の実施例１としての放射冷暖房システム１を設置した室内の概略図が示されており、放射冷暖房システム１は室内２の天井に後述する放射パネル３ａ、３ｂ、３ｃと、この放射パネル３ａ、３ｂ、３ｃに内装されている一連の熱伝導率に優れた金属製等のチューブ１１に連結された送水管４および放水管５と、冷水又は温水を製造する熱交換器９と、送水管４とチューブ１１と放水管５と熱交換器９を介して水を循環させる循環ポンプ１２と、放射パネル３ａ、３ｂ、３ｃとの間隙Ｋに形成された空気噴出ダクト６ａ、６ｂと、空気排気ダクト８と、空気調和機１０から構成されている。該空気調和機１０は、送風機１０ａによって空気排気ダクト８から室内排気を取り込み、同時に外気を取り入れて、エアフィルタ１０ｄで除塵を行い、冷温水コイル１０ｃおよび加湿器１０ｂによって調温調湿を行い、前記空気噴出ダクト６ａ、６ｂを介して室内に調温調湿空気を供給している。該冷温水コイル１０ｃには、熱源機器（開示せず）から例えば７℃程度の一次冷水又は例えば４０℃程度の一次温水が供給され、加湿器１０ｂには加湿用の水又は蒸気が供給されている。なお、本実施例１では、冷温水コイル１０ｃを使用しているが、冷水コイルと温水コイルを個々に設置してもよい。
【００２０】
熱交換器９には、前記冷温水コイル１０ｃと同じく、前記熱源機器から一次冷水又は一次温水が供給されている。循環ポンプ１２から供給された循環水と該一次冷水又は一次温水が熱交換器９によって熱交換され、該循環水が冷房時には冷却されて例えば１５℃程度の冷水として供給され、暖房時には、加熱されて例えば３５℃程度の温水として送水管４を介して前記チューブ１１に供給される。
【００２１】
前記間隙Ｋには図２に示すように、この間隙Ｋに沿う長方形の開口を有する複数個の空気噴出ダクト６ａが図３に示されているように設置されている。
【００２２】
供給された冷水、又は温水は放射パネル３ａ、３ｂ、３ｃ内の一連チューブ１１を通過する間に室内１と放射による熱交換を行い、放射による熱交換を行って温くなった冷水又は冷めた温水は、循環ポンプ１２によって放水管５を介して熱交換器９へと送られ再び冷却、又は加熱され、放射パネル３ａ、３ｂ、３ｃの一連チューブ１１へと還流される。
【００２３】
図４、５に示すように、前記放射パネル３ａ、３ｂ、３ｃの個々の構造は、放射パネル表板１９、冷水又は温水が注入される注入口１５、前述の温まった冷水又は冷めた温水を放水する放水口１７、チューブ１１、断熱材１８及び放射パネル裏板１６とから構成されている。前記チューブ１１の一端は前記注入口１５と他端は前記放水口１７に連通されている。
【００２４】
図５には、図４のＡ―Ａの断面図が示されており、室内への冷房、暖房の放射効率を高めるための熱伝導性に優れた金属製の放射パネル表板１９の上部近傍に一連のチューブ１１が前記放射パネルの長手方向にＵ字型（図４参照）を繰り返すように多数並列に載置され、上方よりグラスウール等の断熱材１８に被覆されている。
【００２５】
さらに、断熱材１８の上部には、金属製又は合成樹脂製等の放射パネル裏板１６が設けられており、一連のチューブ１１と断熱材１８とを放射パネル表板１９とで狭持するように接着剤又はボルト等で固定されている。
【００２６】
上述のように構成された放射冷暖房システムは、冷房時に一連のチューブ１１に上記の方法で供給された例えば１５℃程度の冷水によって、放射パネル表板１９が冷却されると放射パネル表板１９と室内１との温度差で発生する結露粒子に対しては、図１に示すように、放射パネル３ａ、３ｂ、３ｃ間隙Ｋに形成された空気噴出ダクト６ａ、６ｂから空気調和機１０により外気を所定の温度及び湿度に調整された調温調湿空気が調温調湿空気送風管７を介して噴出され、放射パネル３ａ、３ｂ、３ｃそれぞれの放射パネル表板１９（図５参照）面の乾燥を促進できるため結露水を防止できる。
【００２７】
又、図３に示すように、本実施例１には、空気噴出ダクト６ａ、６ｂに金属製又は樹脂製の揺動風向片２１が設けられており、この揺動風向片２１は、揺動風向片２１の上方の調温調湿空気送風管７の所定位置に形成された揺動風向片駆動装置２２を介して、空気噴出ダクト６ａ、６ｂに噴出される調温調湿空気の方向を周期的に変更するようになっている。
【００２８】
図６に示す揺動風向片駆動装置２２について詳細に説明すると、調温調湿空気を利用する軽金属又は合成樹脂製等の風力ロータ２３と、風力ロータ２３に取付けられている駆動シャフト２４及び歯車装置２５と、クランクレバー３０及びクランクレバー３０に連結された回動自在の軸３１と、この軸３１に固定されている揺動風向片２１と、が設けられている。
【００２９】
前記揺動風向片駆動装置２２は、図３に示すように、調温調湿空気送風管７内の空気噴出ダクト６ａの上方近傍に設けられており、矢印３２方向への調温調湿空気の流れによって回転する風力ロータ２３の回転力が図６で説明した駆動シャフト２４を介して歯車装置２５に伝達され、該歯車装置２５によって回転数が所要の状態に制御される。
【００３０】
この制御された回転によりクランクレバー３０の一端は回転し、他端は揺動運動し、この揺動運動は、所定の回転角３３の範囲内で、回動自在の軸３１に伝達されて周期的に揺動風向片２１を回動させる。
【００３１】
この回転角３３の範囲での回動は、前記風力ロータ２３を通過した調温調湿空気の流れを、空気噴出ダクト６ａから揺動風向片２１の回転角３３（図３参照）に影響させながら強制的に誘導する。
【００３２】
例えば、前記調温調湿空気の流れは、図３に示すように、揺動風向片２１の先端部３４が放射パネル３ａに最も近づいた箇所では、放射パネル３ａの放射パネル表板１９に誘導され、揺動風向片２１の先端部３４が室内２の図示していない床面の方向に回動し続けると少しづつ床面の方向に誘導される。
【００３３】
さらに、前記調温調湿空気の流れは、揺動風向片２１の先端部３４が放射パネル３ｂに最も近づく箇所に達するまで回動し続けると、放射パネル３ｂの放射パネル表板１９に誘導され、この回動が揺動風向片２１を所定の回転角３３の範囲で周期的に行われるため、放射パネル表板１９の乾燥と、室内２の滞留した暖気の攪拌と、が可能になる。
【００３４】
このことにより、放射冷暖房システム１の冷房フル稼動時に極めて高い確率で発生する放射パネル表板１９に付着した結露粒子は蒸発し、放射パネル表板１９での結露の増長を防止でき、室内２に発生する適度な気流によって冷涼感（そよぎ）が増幅されるため、放射パネル表板１９の温度を高めに設定でき、省エネを計ることができ、コストダウンが期待できる。例えば、冷房時の室温を２６℃とし、前記放射パネル表面の温度を１８℃とし、室温湿度を７０％以上にして強制的に該放射パネルに結露をさせる実験を行なったところ、該放射パネル表面に結露を生じたが、該放射パネルに隣接して設けられた前記間隙の前記所定箇所から温度２６℃、湿度５０％程度の調温調湿空気を噴出させることによって、該放射パネルに付着した結露の増長が抑えられることを確認し、また、適度な気流があることで快適性が向上することを確認した。
【００３５】
又、放射冷暖房システム１の暖房稼動時に、空気噴出ダクト６ａより噴出された前記調温調湿空気の流れは、天井付近に滞留した暖気を攪拌するとともに、室内２に適度な気流が確保されるため、室内全体の均一な温度を短時間に保持することが可能になり、省エネを計ることができ、コストダウンが期待できる。例えば、暖房時の室温を２２℃とし、前記放射パネル表面の温度を３２℃として実験を行なったところ、該放射パネルに隣接して設けられた前記間隙の前記所定箇所からの調温調湿空気の噴出がない場合は、足元と頭上との間で２℃以上の温度差が生じ、足元の冷えを解消するために該パネル表面の温度を上昇させる必要が認められたが、該所定箇所から温度２２℃、湿度５０％程度の調温調湿空気を噴出させた場合は、部屋全体が２２℃の均一な状態になり、足元の冷えが存在しないことを確認した。
【００３６】
さらに、揺動風向片２１による放射パネル表板１９への調温調湿空気の誘導は、広範囲な乾燥面の確保を可能にし、より確実に結露を防止でき、揺動風向片２１による調温調湿空気の床面への誘導は、室内２に適度な気流を確保することができるため、周期的に滞留した暖気は攪拌し、室内を均一な所定温度に保持することをより確実にする。
【００３７】
本実施例１には、図６の揺動風向片駆動装置が、図３に示した調温調湿空気送風管７内の空気噴出ダクト６ａの上方近傍に設けられており、揺動風向片２１の作動を周期的に変更できるため、放射パネル表板１９への長時間におよぶ風量のかけ過ぎによる放射パネル表板１９の温度の降下時に発生する再結露を防止できるとともに、電力確保のための電気配線工事等を施す必要がなく経済性に富み、調温調湿空気の流れを利用した風力ロータ２３の回転力を使い、電力を使わないため、省エネルギーを計ることができる。
【００３８】
図７は、本実施例２の放射冷暖房システム１を設置した室内の概略図が示されており、放射パネル等の構造及び、冷水又は温水の配管、空気噴出ダクトの構造、又は機能は本実施例１で述べたのでこの実施例では省略する。
【００３９】
本実施例２の放射冷暖房システム１は、放射パネル４０ｂと放射パネル４０ｃとの間隙Ｋ^’、放射パネル４０ｄと放射パネル４０ｅと間隙Ｋ^’が、それぞれ前記の間隙Ｋ^’、Ｋ^’に向かって下降傾斜するように構成されており、放射パネル４０ａと放射パネル４０ｂと間隙Ｋ^’’、放射パネル４０ｃと放射パネル４０ｄと間隙Ｋ^’’、放射パネル４０ｅと放射パネル４０ｆとの間隙Ｋ^’’がそれぞれ前記間隙Ｋ^’’、Ｋ^’’、Ｋ^’’に向かって上昇傾斜する前記冷暖房放射パネルの両端は、照明器具が取付けられるように構成されている。
【００４０】
空気噴出ダクト４１から噴出され、さらに、揺動風向片２１（図６参照）に誘導される調温調湿空気は、放射パネル４０ｂと放射パネル４０ｃ、放射パネル４０ｄと放射パネル４０ｅの各表面の下降傾斜を伝って冷暖房放射パネルの傾斜下端部に集結した結露水の蒸発を促進し、放射パネル表面からの結露水の落下を防止できる。
【００４１】
又、間隙Ｋ^’’に向かって上昇傾斜するように配設された冷暖房放射パネルの傾斜上端部が、照明器具の放射熱に暖められて、わずかな結露粒子の発生をも防止できる。
【００４２】
以上、本発明の実施例を図面により説明してきたが、具体的な構成はこれら実施例に限られるものではなく、本発明の要旨を逸脱しない範囲における変更や追加があっても本発明に含まれる。
【００４３】
例えば、チューブ１１が放射パネルの長手方向にＵ字型（図４参照）を繰り返すように多数並列に載置されているが、例えば１本のチューブをＳ字型を繰り返すように載置するなど、確実に効率よく放射冷暖房できるチューブ１１の配管であれば良く、断熱材１８の素材はグラスウール等に限られるものでなく、チューブ１１の放射が、室内への効率よい放射冷暖房に影響を及ぼさない材料であれば良い。
【００４４】
例えば、放射パネルは金属製を使用しているが、冷水、温水、調温調湿空気の配管等を支えられる耐久性を備えていれば素材にこだわるものではない。又、実施例２の冷暖房放射パネルの傾斜角度は、冷暖房放射パネルの傾斜下端部に結露水を集結でき、結露水の蒸発の促進と、結露水の落下を防止できる範囲の傾きを維持できれば良く、天井面の見栄えが保たれれば良い。
【００４５】
例えば、調温調湿空気の流れを利用した風力ロータ２３の回転力を使い、省エネを計ったが、別の動力によりコスト削減と省エネと静寂さが保持でき、揺動風向片を周期的に回動できるものであれば良い。
【００４６】

Conventionally, a comfortable condition is maintained by placing a tube or the like on the panel surface, passing cold water or hot water inside, keeping the panel surface at a predetermined temperature, and exchanging heat with the wall or human body by radiation. Radiant air conditioning systems have been developed.
[0003]
The advantage of this radiant cooling and heating system is that unlike a general air conditioning system that supplies cold air or hot air, the radiant panel is installed on the entire ceiling surface, so there is little temperature variation in the indoor space and temperature changes due to time, and temperature setting is also possible. It can be relaxed and the economic effect can be enhanced. In addition, since there is no equipment as a sound source at the radiation panel installation location, silence is secured in the room.
[0004]
It is widely adopted for air conditioning in spaces that require a quiet and soft environment such as libraries, hospitals, and nursing homes where these advantages can be effectively utilized. As shown in FIG. The radiating panel 02 is disposed on the entire ceiling of the room 01 without any gaps, and a series of tubes 03 are incorporated in the radiating panel 02.
[0005]
In the tube 03, cold water cooled to, for example, about 15 ° C. during cooling by the heat exchanger 08 installed in a predetermined place and operation of the circulation pump 010, and hot water heated to, for example, about 35 ° C. during heating. Injected through the insertion tube 04. The heat exchanger 08 is supplied with, for example, primary cold water of about 7 ° C. or primary hot water of about 40 ° C., for example, from a heat source device (not disclosed), and cools the hot water supplied to the tube 03 or heats the hot water. Is going.
[0006]
Further, while the injected cold water or hot water passes through a series of tubes 03 in the radiation panel 02, heat exchange is performed with the room 01 by radiation, and the room 01 temperature is adjusted to a predetermined set temperature. Heat exchange is performed with the room 01 by radiation, and the warm water or the warm water whose temperature has been lowered is sent to the heat exchanger 08 through the discharge pipe 05 and cooled or heated again to the tube 03 of each radiation panel 02. And refluxed.
[0007]
An air jet duct 06 is provided in the vicinity of one ceiling of the room 01, and an air exhaust duct 07 is provided in the vicinity of the other ceiling. The air jet duct 06 is temperature-controlled by an air conditioner 09. The purpose of preventing or removing dew condensation on the surface of the radiating panel 02 caused by the introduction of outside air necessary for ventilation and the temperature difference between the radiating panel 02 and the room 01 during cooling as will be described later This prevents the warm air during heating from staying near the ceiling and keeps the room 01 at a uniform temperature. The air conditioner 09 is supplied with primary cold water of about 7 ° C. or primary hot water of about 40 ° C., for example, from the heat source device, and is further supplied with water or steam for humidification, and is supplied to the air ejection duct 06. Air conditioning and humidity control.
[0008]
On the other hand, the air exhaust duct 07 is provided for the purpose of discharging humid air in the room 01 during cooling, and for promoting the flow of air staying in the room 01 during heating and for promoting the agitation of air by the airflow.
[0009]
[Problems to be solved by the invention]
However, the radiant cooling and heating system is not a heat exchange by convection by supplying cold air or hot air into the room like a general air conditioning system, but from the temperature difference between the surface temperature of the radiant panel and the surface temperature of the wall or human body. Since heat exchange is mainly performed by the generated radiation and natural convection, a temperature difference is required between the radiation panel and the room.
[0010]
For this reason, it is necessary to keep the temperature of the radiant panel surface lower than room temperature during cooling, so that water vapor generated in the room is condensed on the surface of the radiant panel in a low temperature state and condensation occurs.
[0011]
In addition, during heating, since the induction of warm air is not performed using wind power unlike a general air conditioning system, warm air warmed on the surface of the radiant panel stays near the ceiling and maintains the entire room at a uniform temperature. It was difficult to do.
[0012]
The conventional radiant air-conditioning system described above is provided with the air ejection duct 06 of FIG. 1 as a method for eliminating the above-described condensation prevention and uneven room temperature adjustment as much as possible. Since the temperature-controlled and humid air is limited to an air volume that is weak enough not to disturb the quietness of the room 01, it is possible to prevent condensation on the surface of the radiation panel 02 in the vicinity of the air ejection duct 06, but the air ejection duct 06. Because the temperature-controlled and humidity-controlled air does not reach the surface of the radiating panel 02 that is far from the water, condensation occurs. In particular, a lot of condensation occurs near the cold water inlet of the tube 03 during cooling, and finally condensation occurs. It became water, falling on the floor, causing stains on the rug, and causing unclean indoor environment such as generation of mold at locations where condensed water accumulated. In addition, although the stay of warm air near the ceiling during heating can be eliminated in the vicinity of the air ejection duct 06, the residence of warm air cannot be eliminated except in the vicinity of the air ejection duct 06, and the room 01 can be maintained at a uniform predetermined temperature. It was difficult.
[0013]
The present invention has been made paying attention to such problems, and provides a radiant cooling and heating system that prevents condensation on the surface of the radiant panel during cooling and stagnation of warm air near the ceiling during heating. Objective.
[0014]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a radiant cooling / heating system according to the present invention is provided with a gap in a predetermined cooling / heating radiant panel, an air jet duct provided with a swinging airflow direction piece at a predetermined position of the gap, It is characterized in that air can be ejected from the air ejection duct.
According to this feature, during the cooling operation of the radiant cooling and heating system, the air conditioned and temperature-controlled from a predetermined portion of the gap provided adjacent to the radiant panel is ejected through the oscillating air direction piece. Since the air is evenly supplied to the surface of the radiant panel, condensation particles adhering to the surface of the radiant panel evaporate, and it is possible to prevent the condensation from increasing on the surface of the radiant panel, and the condensed water falls to the floor, causing stains on the rug. This can prevent unsanitary indoor environments such as molds that form and the presence of condensed water, and the airflow generated in the room amplifies the coolness of the radiant panel. The surface temperature can be set higher, energy saving can be measured, and cost reduction can be expected. For example, when the room temperature during cooling was set to 26 ° C., the temperature of the surface of the radiating panel was set to 18 ° C., and the room temperature humidity was set to 70% or more, forcibly dew condensation was performed on the radiating panel. Condensation has occurred on the surface, but it adheres to the radiating panel by ejecting temperature-controlled air with a temperature of about 26 ° C. and a humidity of about 50% from the predetermined portion of the gap provided adjacent to the radiating panel. It was confirmed that the increase in condensation was suppressed, and the comfort was improved by the presence of moderate airflow.
In addition, during the heating operation of the radiant cooling and heating system, the air that has been temperature-controlled and humidity-controlled is ejected from a predetermined portion of the gap provided adjacent to the radiant panel through the oscillating wind direction piece. While stirring the warm air staying near the ceiling and ensuring an appropriate air flow in the room, it is possible to maintain a uniform temperature throughout the room in a short time, thereby saving energy and reducing costs. I can expect. For example, when the experiment was performed by setting the room temperature during heating to 22 ° C. and the temperature of the surface of the radiating panel to 32 ° C., the temperature-controlled air from the predetermined portion of the gap provided adjacent to the radiating panel When there was no eruption of water, a temperature difference of 2 ° C. or more was generated between the feet and the head, and it was recognized that the temperature of the panel surface had to be raised in order to eliminate the cooling of the feet. When temperature-controlled humidity air having a temperature of 22 ° C. and a humidity of about 50% was ejected, it was confirmed that the entire room was in a uniform state of 22 ° C. and there was no cooling of the feet.
[0015]
In the radiant cooling and heating system according to the present invention, it is preferable that the oscillating airflow direction piece is rotatable by using wind force.
In this way, since the wind power that is blown is used, it is not necessary to carry out electrical wiring work and the like, which is economical and energy saving, and the operation of the oscillating wind direction piece is periodically performed. Since it can be changed, it is possible to prevent re-condensation that occurs when the surface temperature of the radiating panel drops due to excessive application of airflow over a long period of time.
[0016]
In the radiant cooling and heating system of the present invention, it is preferable that the cooling and heating radiant panels on both sides of the gap are formed so as to be inclined downward toward the gap.
In this way, the temperature-controlled and humidity-controlled air ejected from the air ejection duct concentrates and evaporates the condensed water that has been automatically collected at the inclined lower end portion along the descending inclined surface of the radiating panel surface. It is possible to efficiently prevent the condensed water from falling on the surface of the radiant panel.
[0017]
In the radiant cooling and heating system of the present invention, it is preferable that a lighting fixture is supported in a gap formed on the rising slope side of an adjacent cooling and heating radiant panel.
In this way, the inclined upper end of the cooling / heating radiating panel disposed so as to be inclined upward toward the gap is warmed by the radiant heat of the luminaire, and generation of slight condensation particles can be prevented. .

[0019]
First, FIG. 1 shows a schematic view of a room in which a radiant cooling and heating system 1 according to a first embodiment of the present invention is installed. The radiant cooling and heating system 1 includes radiating panels 3a, 3b, 3c, which will be described later, on the ceiling of the room 2. , A water supply pipe 4 and a water discharge pipe 5 connected to a series of tubes 11 made of metal having excellent thermal conductivity and installed in the radiation panels 3a, 3b and 3c, and a heat exchanger for producing cold water or hot water 9, an air jet duct 6a formed in a gap K between the water supply pipe 4, the tube 11, the water discharge pipe 5, and the circulation pump 12 that circulates water through the heat exchanger 9 and the radiation panels 3a, 3b, 3c, 6b, an air exhaust duct 8, and an air conditioner 10. The air conditioner 10 takes in the indoor exhaust from the air exhaust duct 8 by the blower 10a, simultaneously takes in the outside air, removes the dust by the air filter 10d, adjusts the temperature by the cold / hot water coil 10c and the humidifier 10b, Temperature-controlled and humidity-controlled air is supplied into the room through the air jet ducts 6a and 6b. For example, primary cold water of about 7 ° C. or primary hot water of about 40 ° C., for example, is supplied from the heat source device (not disclosed) to the cold / hot water coil 10c, and water or steam for humidification is supplied to the humidifier 10b. Yes. In addition, in the present Example 1, although the cold / hot water coil 10c is used, you may install a cold water coil and a hot water coil separately.
[0020]
As with the cold / hot water coil 10c, the heat exchanger 9 is supplied with primary cold water or primary hot water from the heat source device. The circulating water supplied from the circulation pump 12 and the primary cold water or primary hot water are heat-exchanged by the heat exchanger 9, and the circulating water is cooled during cooling and supplied as cold water of about 15 ° C., for example, and heated during heating. For example, hot water of about 35 ° C. is supplied to the tube 11 through the water supply pipe 4.
[0021]
As shown in FIG. 2, a plurality of air ejection ducts 6a having rectangular openings along the gap K are installed in the gap K as shown in FIG.
[0022]
The supplied cold water or hot water exchanges heat with the room 1 by radiation while passing through the series of tubes 11 in the radiant panels 3a, 3b, 3c, and heat water that has been warmed or cooled by performing heat exchange by radiation. Is sent to the heat exchanger 9 through the water discharge pipe 5 by the circulation pump 12, cooled or heated again, and returned to the series of tubes 11 of the radiation panels 3a, 3b, 3c.
[0023]
As shown in FIGS. 4 and 5, the individual structures of the radiating panels 3a, 3b, and 3c include the radiating panel surface plate 19, the injection port 15 into which cold water or hot water is injected, and the above-mentioned warm cold water or cold hot water. It is comprised from the water outlet 17 which discharges water, the tube 11, the heat insulating material 18, and the radiation panel backplate 16. As shown in FIG. One end of the tube 11 communicates with the inlet 15 and the other end communicates with the water outlet 17.
[0024]
FIG. 5 is a cross-sectional view taken along the line AA of FIG. 4, in the vicinity of the upper portion of the metal radiant panel top plate 19 excellent in thermal conductivity for enhancing the radiation efficiency of cooling and heating indoors. A plurality of tubes 11 are placed in parallel so as to repeat a U-shape (see FIG. 4) in the longitudinal direction of the radiation panel, and are covered with a heat insulating material 18 such as glass wool from above.
[0025]
Further, a radiating panel back plate 16 made of metal or synthetic resin is provided on the top of the heat insulating material 18 so that the series of tubes 11 and the heat insulating material 18 are held between the radiating panel front plate 19. Are fixed with an adhesive or bolts.
[0026]
The radiant cooling and heating system configured as described above is configured such that, when the radiant panel front plate 19 is cooled by, for example, about 15 ° C. cold water supplied to the series of tubes 11 by the above method during cooling, As shown in FIG. 1, dew particles generated due to a temperature difference from the room 1 are discharged from the air discharge ducts 6 a and 6 b formed in the gaps K of the radiation panels 3 a, 3 b and 3 c by the air conditioner 10. Temperature-controlled and humidity-adjusted air adjusted to a predetermined temperature and humidity is ejected through the temperature-controlled and humidity-controlled air blowing pipe 7, and the surfaces of the radiant panel front plates 19 (see FIG. 5) of the radiant panels 3a, 3b, and 3c, respectively. Drying can be promoted to prevent condensation.
[0027]
Further, as shown in FIG. 3, in the first embodiment, the air jet ducts 6a and 6b are provided with a rocking air direction piece 21 made of metal or resin, and the rocking air direction piece 21 is rocked. The direction of the temperature-controlled and humidity-controlled air ejected to the air ejection ducts 6a and 6b via the oscillating air direction piece driving device 22 formed at a predetermined position of the temperature-controlled humidity-controlled air blowing pipe 7 above the air-direction piece 21 It is supposed to change periodically.
[0028]
The rocking wind direction piece drive device 22 shown in FIG. 6 will be described in detail. A wind rotor 23 made of light metal or synthetic resin using temperature-controlled humidity air, a drive shaft 24 and a gear attached to the wind rotor 23. A device 25, a crank lever 30, a rotatable shaft 31 connected to the crank lever 30, and a swinging air direction piece 21 fixed to the shaft 31 are provided.
[0029]
As shown in FIG. 3, the oscillating air direction piece driving device 22 is provided in the vicinity of the upper portion of the air jet duct 6 a in the temperature-controlled humidity-control air blowing pipe 7, and temperature-controlled humidity-controlled air in the direction of arrow 32. The rotational force of the wind-powered rotor 23 that is rotated by this flow is transmitted to the gear device 25 via the drive shaft 24 described in FIG. 6, and the gear device 25 controls the rotational speed to a required state.
[0030]
With this controlled rotation, one end of the crank lever 30 rotates and the other end swings, and this swinging motion is transmitted to the pivotable shaft 31 within a predetermined rotation angle 33 and cycled. Thus, the oscillating air direction piece 21 is rotated.
[0031]
The rotation in the range of the rotation angle 33 affects the rotation angle 33 (see FIG. 3) of the oscillating airflow direction piece 21 from the air ejection duct 6a by the flow of the temperature-controlled humidity air that has passed through the wind turbine rotor 23. While forcibly inducing.
[0032]
For example, as shown in FIG. 3, the flow of the temperature-conditioned air is guided to the radiating panel front plate 19 of the radiating panel 3a when the tip 34 of the swing airflow direction piece 21 is closest to the radiating panel 3a. If the tip 34 of the oscillating airflow direction piece 21 continues to rotate in the direction of the floor surface (not shown) of the room 2, it is guided little by little in the direction of the floor surface.
[0033]
Further, the flow of the temperature-controlled humidity-controlled air is guided to the radiating panel front plate 19 of the radiating panel 3b as it continues to rotate until the tip 34 of the oscillating airflow direction piece 21 reaches the position closest to the radiating panel 3b. Since the rotation of the oscillating airflow direction piece 21 is periodically performed within the range of the predetermined rotation angle 33, the radiating panel front plate 19 can be dried and the warm air staying in the room 2 can be stirred.
[0034]
As a result, the dew condensation particles adhering to the radiant panel surface plate 19 which are generated with a very high probability when the radiant cooling and heating system 1 is fully operated are evaporated, and the increase of the dew condensation on the radiant panel surface plate 19 can be prevented. Since the cool feeling is amplified by the moderate airflow generated, the temperature of the radiating panel surface plate 19 can be set high, energy saving can be achieved, and cost reduction can be expected. For example, when the room temperature during cooling was set to 26 ° C., the temperature of the surface of the radiating panel was set to 18 ° C., and the room temperature humidity was set to 70% or more, forcibly dew condensation was performed on the radiating panel. Condensation has occurred on the surface, but it adheres to the radiating panel by ejecting temperature-controlled air with a temperature of about 26 ° C. and a humidity of about 50% from the predetermined portion of the gap provided adjacent to the radiating panel. It was confirmed that the increase in condensation was suppressed, and the comfort was improved by the presence of moderate airflow.
[0035]
Further, during the heating operation of the radiant cooling and heating system 1, the flow of the temperature-controlled and humidity-controlled air ejected from the air ejection duct 6 a agitates the warm air remaining in the vicinity of the ceiling and ensures an appropriate air flow in the room 2. Therefore, it becomes possible to maintain a uniform temperature throughout the room in a short time, energy saving can be achieved, and cost reduction can be expected. For example, when the experiment was performed by setting the room temperature during heating to 22 ° C. and the temperature of the surface of the radiating panel to 32 ° C., the temperature-controlled air from the predetermined portion of the gap provided adjacent to the radiating panel When there was no eruption of water, a temperature difference of 2 ° C. or more was generated between the feet and the head, and it was recognized that the temperature of the panel surface had to be raised in order to eliminate the cooling of the feet. When temperature-controlled humidity air having a temperature of 22 ° C. and a humidity of about 50% was ejected, it was confirmed that the entire room was in a uniform state of 22 ° C. and there was no cooling of the feet.
[0036]
Furthermore, the induction of temperature-controlled and humidity-controlled air to the radiating panel surface plate 19 by the oscillating air direction piece 21 makes it possible to secure a wide range of dry surfaces, more reliably prevent condensation, and temperature adjustment by the oscillating air direction piece 21. The induction of the humidity-controlled air to the floor surface can secure an appropriate air flow in the room 2, so that the warm air staying periodically is agitated to make sure that the room is kept at a uniform predetermined temperature. .
[0037]
In the first embodiment, the oscillating air direction piece driving device of FIG. 6 is provided in the vicinity of the upper portion of the air jet duct 6a in the temperature-controlled and humidity-controlled air blowing pipe 7 shown in FIG. Since the operation of 21 can be changed periodically, it is possible to prevent re-condensation that occurs when the temperature of the radiating panel surface plate 19 drops due to excessive air flow over a long time on the radiating panel surface plate 19, and to secure power Therefore, it is possible to save energy by using the rotational force of the wind rotor 23 using the flow of temperature-controlled humidity air and not using electric power.
[0038]
FIG. 7 shows a schematic diagram of a room in which the radiant cooling and heating system 1 of the second embodiment is installed. The structure of the radiant panel and the like, the structure of cold water or hot water, the structure of the air ejection duct, or the function are shown in FIG. Since it was described in Example 1, it is omitted in this embodiment.
[0039]
In the radiant cooling and heating system 1 of the second embodiment, the gap K ^′ between the radiant panel 40b and the radiant panel 40c, and the radiant panel 40d, the radiant panel 40e, and the gap K ^′ are lowered toward the gaps K ^′ and K ^′ , respectively. The radiating panel 40a and the radiating panel 40b and the gap K ^'' , the radiating panel 40c and the radiating panel 40d and the gap K ^'' , and the radiating panel 40e and the radiating panel 40f, respectively, have a gap K ^''. Both ends of the cooling / heating radiating panel that is inclined upward toward the gaps K ^″ , K ^″ , K ^″ are configured to be attached with lighting fixtures.
[0040]
The temperature-controlled and humidity-controlled air that is ejected from the air ejection duct 41 and is guided to the oscillating airflow direction piece 21 (see FIG. 6) is emitted from each surface of the radiation panel 40b and the radiation panel 40c, the radiation panel 40d, and the radiation panel 40e. It is possible to promote the evaporation of the condensed water gathered on the inclined lower end of the cooling / heating radiant panel through the descending inclination and prevent the condensed water from falling from the surface of the radiant panel.
[0041]
Further, the inclined upper end portion of the cooling / heating radiating panel arranged so as to be inclined upward toward the gap K ^″ is heated by the radiant heat of the lighting fixture, and the generation of slight condensation particles can be prevented.
[0042]
Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.
[0043]
For example, many tubes 11 are placed in parallel so as to repeat a U-shape (see FIG. 4) in the longitudinal direction of the radiation panel. For example, one tube is placed so as to repeat an S-shape. As long as the pipe of the tube 11 can be reliably and efficiently radiant-cooled and heated, the material of the heat insulating material 18 is not limited to glass wool or the like, and the radiation of the tube 11 does not affect the efficient radiant cooling and heating indoors. Any material can be used.
[0044]
For example, the radiant panel is made of metal, but it does not stick to the material as long as it has the durability to support piping of cold water, hot water, temperature-controlled air, and the like. In addition, the inclination angle of the cooling / heating radiating panel of the second embodiment is only required to be able to collect condensed water at the inclined lower end of the cooling / heating radiating panel, to maintain the inclination within a range where condensation water can be promoted and the condensed water can be prevented from falling. As long as the appearance of the ceiling is maintained.
[0045]
For example, the rotational force of the wind rotor 23 using the flow of temperature-controlled humidity air was used to save energy, but cost savings, energy saving and quietness can be maintained with different power, and the oscillating wind direction piece can be periodically Anything that can rotate is acceptable.
[0046]
