【発明の属する技術分野】
本発明は、深夜電力を利用して夜間などにスラブに冷熱や温熱を蓄え、その蓄えられた熱を昼間の空調に利用し、経済的に空調を行えるようにするとともに空調負荷のピークカットを図る躯体蓄熱型空気調和システムに関する。
【0002】
【従来の技術】
従来の躯体蓄熱型空気調和システムとしては、図16の概略構成図に示すようなものがあった。
すなわち、スラブ01と天井板02との間に閉空間Sが形成されるとともに、閉空間S内にダクト03が設けられている。
ダクト03の所定箇所に、冷風あるいは温風といった温調空気を閉空間S側に吹き出す第1の吹き出し口04と、室内空間R側に吹き出す第2の吹き出し口05とが設けられている。
【0003】
熱交換によって温調空気を得るために、機械室などに設置されたヒートポンプなどの熱交換器06からの配管07がダクト03に接続されている。第1の吹き出し口04と第2の吹き出し口05との間に切り替えダンパー08が設けられ、温調空気をダクト03から閉空間S内に吹き出して冷熱あるいは温熱をスラブ01に蓄える蓄熱状態と、蓄熱されたスラブ01からの自然放熱を利用しながら温調空気を室内空間R側に吹き出す空調状態とに切り替えることができるように構成されている。
【0004】
【発明が解決しようとする課題】
しかしながら、従来例の場合、第1の吹き出し口04自体の開口面積が大きいものの、閉空間S内でのスラブ01の表面積の割に、温調空気が第1の吹き出し口04から吹き付けられる面積が小さく、スラブ01に対して局部的(図中A部)に蓄熱されるだけであり、全体の蓄熱量が少ない欠点があった。
【0005】
本発明は、このような事情に鑑みてなされたものであって、請求項1に係る発明の躯体蓄熱型空気調和システムは、スラブへの蓄熱量を増大できるようにすることを目的とし、請求項2、請求項3、請求項4それぞれに係る発明の躯体蓄熱型空気調和システムは、スラブへの蓄熱を効率良く行えるようにすることを目的とする。
【0006】
【課題を解決するための手段】
請求項1に係る発明は、上述のような目的を達成するために、スラブと天井板または床板との間に閉空間を形成し、熱交換によって温調空気を得る熱交換器を設けるとともに、その熱交換器からの温調空気を閉空間内に供給してスラブに熱を蓄えるように構成した躯体蓄熱型空気調和システムにおいて、温調空気を閉空間内のスラブの表面にその法線方向に向かって吹き付ける吹き出し口を、スラブの表面に沿って分散配置して構成する。
【0007】
また、請求項2に係る発明は、前述のような目的を達成するために、請求項1に記載の躯体蓄熱型空気調和システムにおいて、
吹き出し口をスリット状に形成する。
【0008】

スラブの表面に伝熱促進部材を付設して構成する。
【0010】
【作用】
請求項1に係る発明の構成による作用は次の通りである。
すなわち、熱伝達分布について考察した結果、図1の模式図に示すように、吹き出し口1からスラブ2の表面にその法線方向に向かって温調空気を吹き出したときに、熱伝達率(単位面積当り、単位時間当りの熱の移動量)Qが衝突箇所Tで非常に高くなり、スラブ2の表面に沿って温調空気を流した場合の数倍以上にも及ぶことに着目し、スラブ2の表面の法線方向に向かわせる衝突噴流を利用してスラブ2に伝熱することができる。
【0011】
また、請求項2に係る発明の構成によれば、スリット状の吹き出し口により、衝突中心を線的に広げ、少ない個数の吹き出し口でスラブ全体にわたって蓄熱できる。
【0012】
また、請求項3に係る発明の構成によれば、凹凸面に形成したスラブの表面の凹部に温調空気を吹き付け、更に、反射した温調空気が直接閉空間内に拡がらずに凹部内の周壁面に沿って流れ、スラブに伝熱することができる。
【0013】
また、請求項4に係る発明の構成によれば、衝突噴流による伝熱に加え、伝熱促進部材を介してスラブに伝熱することができる。
【0014】
【発明の実施の形態】
次に、本発明の実施例を図面に基づいて詳細に説明する。
【0015】
図2は、本発明の躯体蓄熱型空気調和システムに係る第1実施例を示す全体システム構成図であり、スラブ2の下面と天井板3との間に閉空間Sが形成されるとともに、閉空間S内にダクト4が設けられている。
【0016】
ダクト4の所定箇所の上方側に、冷風あるいは温風といった温調空気を閉空間S側に吹き出す第1の吹き出し口5が設けられ、一方、下方側に、室内空間R側に吹き出す第2の吹き出し口6が設けられている。
【0017】
ダクト4には、熱交換によって温調空気を得るヒートポンプなどの熱交換器7からの配管8が接続されている。第1の吹き出し口5と第2の吹き出し口6との間に切り替えダンパー9が設けられ、温調空気をダクト4から閉空間S内に吹き出して冷熱あるいは温熱をスラブ2に蓄える蓄熱状態(実線で示す)と、スラブ2からの自然放熱を利用しながら温調空気を室内空間R側に吹き出す空調状態(二点鎖線で示す)とに切り替えることができるように構成されている。
【0018】
第1の吹き出し口5には、分岐ダクト10が接続されている。分岐ダクト10の上方側は、鉛直方向には比較的薄くて平面方向には大きな面積の箱状体に構成され、分岐ダクト10の上面に、縦横に所定間隔を隔てて、スラブ2の表面にその法線方向に向かって温調空気を吹き付けるように、ノズル状の第3の吹き出し口1(作用で説明した吹き出し口に対応する)が設けられている。
【0019】
以上の構成により、蓄熱時において、スラブ2の表面に沿って分散配置された第3の吹き出し口1からスラブ2の表面に温調空気を吹き付け、その衝突噴流により伝熱し、冷熱または温熱をスラブ2内に蓄えることができるようになっている。
【0020】
図3は、本発明の躯体蓄熱型空気調和システムに係る第2実施例を示す要部の斜視図、図4は図3の断面図であり、第1実施例と異なるところは次の通りである。
【0021】
すなわち、ダクト4に接続される分岐ダクト11が直方体形状に構成され、その分岐ダクト11に、長手方向に所定間隔を隔ててスリット状の第4の吹き出し口12が設けられている。他の構成は第1実施例と同じである。
この第2実施例によれば、第1実施例に比べ、構成が簡単で組付けも容易になり、システムを安価に構築できる利点がある。
【0022】
図5は、本発明の躯体蓄熱型空気調和システムに係る第3実施例を示す要部の断面図であり、第2実施例と異なるところは次の通りである。
【0023】
すなわち、スラブ2の表面が波状凹凸面13に形成され、その所定間隔おきの凹部13aに、その法線方向に向かうようにスリット状の第4の吹き出し口12からの温調空気が吹き付けられるように構成されている。他の構成は第2実施例と同じである。
【0024】

この第4実施例の構成によれば、各凹部14a内に沿って第4の吹き出し口12を入れ込ませることができるから、分岐ダクト11を配設するためのスペースを少なくできる利点がある。他の構成は第2実施例と同じである。
【0026】
上記第3実施例および第4実施例によれば、スラブ2の表面を凹凸面13,14に形成することにより、伝熱面積を拡大できている。また、凹部13a,14aに温調空気を吹き付けることにより、反射した温調空気が直接閉空間S内に拡がらずに凹部13a,14a内の周壁面に沿って流れ、スラブ2への熱伝達を向上できるという効果がある。
【0027】
図7は、本発明の躯体蓄熱型空気調和システムに係る第5実施例を示す要部の断面図、図8は、図7を下方から見た図であり、第1実施例と異なるところは次の通りである。
【0028】
すなわち、閉空間S内のスラブ2の表面に、コンクリートよりも熱伝導率が高い伝熱促進部材としての鋼製のアングル材15がアンカーボルト15aにより格子状に取り付けられている。前述のような分岐ダクト10が省略され、第1の吹き出し口5からアングル材15およびスラブ2の表面に温調空気を吹き付けるように構成されている。他の構成は第1実施例と同じである。
【0029】
この第5実施例によれば、温調空気の熱がスラブ2の表面に伝えられるとともにアングル材15に伝えられる。アングル材15の熱伝導率が高いために、スラブ2の表面に沿って流れる温調空気からの熱もアングル材15およびアンカーボルト15aに効率良く伝えられ、更に、アングル材15およびアンカーボルト15aを介して早期に熱をスラブ2に伝えてゆき、効率良くスラブ2に蓄熱できる。

【0031】
鋼棒17の閉空間S内に突出した部分に、ダクト18の吹き出し口19を通じて温調空気を供給するように構成されている。伝熱促進部材としては、鋼棒17に代えて番線を束ねたものなど、コンクリートよりも熱伝導率が高い材料を用いるものであれば各種のものが適用できる。
【0032】
この第6実施例によれば、温調空気の熱がスラブ2の表面に伝えられるとともに鋼棒17に伝えられる。鋼棒17の熱伝導率が高いために、温調空気の熱が鋼棒17に効率良く伝えられ、更に、鋼棒17を介して早期に熱を鉄筋16に伝えてゆき、鋼棒17および鉄筋16を通じて、スラブ2の内部まで伝え、効率良くスラブ2に蓄熱できる。
【0033】

【0034】
伝熱促進部材としては、上述のような鍔体20に代えて、図11の(a)の側面図に示すように、細い番線21の複数本を鋼棒17に付設するとか、図11の(b)の斜視図に示すように、薄い鋼板22を付設するとか、あるいは、図11の(c)の斜視図に示すように、鋼製のスパイラル部材23を付設するなど各種の構成が採用できる。
【0035】
図12は、本発明の躯体蓄熱型空気調和システムに係る第8実施例を示す全体システム構成図であり、鉄骨コンクリート構造体などにおいてスラブ2内に埋設された鉄骨24に、その長手方向に所定間隔を隔てて伝熱促進部材としての鋼製筒体25が溶接により連接され、その鋼製筒体25の下端が閉空間S内に突出されている。
【0036】
鉄骨24は、図13の(a)の断面図[図12のA−A線縦断面図]に示すように、H型鋼で構成されるとともに、そのウェブ24a内に長手方向に連なる中空部26が形成されている。更に、中空部26と鋼製筒体25とにわたり、図13の(b)の断面図[図12のB−B線縦断面図]に示すように、閉空間Sと中空部26を連通する中空管路27が形成されている。
【0037】
この第8実施例によれば、温調空気の熱がスラブ2の表面に伝えられるとともに鋼製筒体25に伝えられる。鋼製筒体25の熱伝導率が高いために、温調空気の熱が鋼製筒体25に効率良く伝えられ、鋼製筒体25を介して鉄骨24に伝えられるとともに、温調空気が中空管路27から中空部26に流入されて鉄骨24に伝えられ、鋼製筒体25および鉄骨24を通じて、スラブ2の内部まで伝え、効率良くスラブ2に蓄熱できる。

【0040】
この第9実施例によれば、流入される温調空気の熱を蓄熱材29に蓄え、より一層効率良くスラブ2に蓄熱できる。
【0041】
本発明としては、上述実施例のように、スラブ2と天井板3との間に閉空間Sを形成し、そこに温調空気を供給して躯体蓄熱を行うように構成するものに限らず、例えば、スラブ2とその上部の床板との間に閉空間を形成し、その閉空間に温調空気を供給して躯体蓄熱を行うように構成するものでも良い。
【0042】
【発明の効果】
以上説明したように、請求項1に係る発明によれば、衝突噴流を利用してスラブに伝熱し、分散配置された吹き出し口それぞれによるスラブへの衝突箇所での熱伝達率を大幅に高くするから、全体として、スラブへの蓄熱量を増大できるようになった。
【0043】
また、請求項2に係る発明によれば、吹き出し口をスリット状にして、衝突中心を線的に広げるから、例えば、吹き出し口をノズル状にした場合に比べ、吹き出し口の個数を少なくできながらスラブ全体に容易に蓄熱でき、構成的に簡単にできるとともに組付けも簡単になり、スラブへの蓄熱を経済的にかつ効率良く行えるようになった。
【0044】
また、請求項3に係る発明によれば、凹凸面に形成したスラブの表面の凹部に温調空気を吹き付け、温調空気の拡散を抑えることができ、更に、反射した温調空気が直接閉空間内に拡がらずに凹部内の周壁面に沿って流れるから、スラブへの熱伝達を向上でき、スラブへの蓄熱を効率良く行えるようになった。
【0045】
また、請求項4に係る発明によれば、衝突噴流による伝熱に加え、伝熱促進部材を介してもスラブに伝熱するから、スラブへの蓄熱を効率良く行えるようになった。
