In azeotropic (like), the presence or absence of azeotropic point does not matter. It suffices if the gas-liquid equilibrium composition of the gas phase portion and the liquid phase portion substantially match.

本実施形態では、第1実施形態で述べた共沸(様)組成物を含む熱伝達媒体を用いる熱伝達システム、および当該システムを利用する熱伝達方法について、図面を参照して説明する。なお、当該熱伝達媒体及び熱伝達方法は、パッケージ型の小型装置だけでなく、工場スケールの大規模システムにも適用可能である。
冷凍サイクルシステムとは、蒸発器で空気、水又はブライン、シリコーンオイルなどの被冷却物が有する熱を冷媒の蒸発潜熱として移動させ、発生した冷媒蒸気を圧縮機において仕事を加えて圧縮し、凝縮器で凝縮熱を排出して液化し、凝縮した冷媒を膨張弁で低圧・低温に絞り膨張させ、蒸発器に送り込んで蒸発させるシステムである。このシステムでは、蒸発器において被冷却物が有する熱エネルギーを冷媒が受け取ることにより、被冷却物を冷却し、より低い温度へ降温する。このシステムは、凝縮器において冷媒の熱エネルギーを負荷流体に与えることにより、負荷流体を加熱し、より高い温度に昇温するシステムであることから、様々な公知のシステムに適用できる。本発明の実施形態の一つに係る冷凍サイクルシステムでは、蒸発器と凝縮器において、冷媒として第1実施形態で述べた熱伝達媒体が用いられる。これにより、10℃以下、7℃以下、又は5℃以下の冷水を生成することができる。
(a)熱交換器(蒸発器11)内で液体状態の冷媒を被冷却流体(空気、水など)と熱交換させ、気化させる。
(b)熱交換器から気化した冷媒を取り出し、気化した冷媒を圧縮機12に通し、高圧の過熱蒸気を供給する。
(c)圧縮機12から出た冷媒を凝縮器13へ通し、気体状態の冷媒を被加熱流体(空気、水など)と熱交換させ、液化させる。
(d)液化した冷媒を膨張弁14により絞り膨張させ、低圧の湿り蒸気を供給し、工程(a)へ再循環させる。
以下、本発明の実施形態に係る高温ヒートポンプサイクルシステムについて説明する。高温ヒートポンプサイクルシステムは、図1に示した冷凍サイクルシステム100に類似する蒸気圧縮式の熱伝達システムであって、凝縮器における熱交換による加熱を目的とするシステムである。ここでは、凝縮器と蒸発器に用いられる作動媒体として本発明の実施形態に係る熱伝達媒体が用いられる。これより、60℃以上又は80℃以上、110℃以上の熱水、加圧熱水又は水蒸気を生成することができる。なお、高温ヒートポンプサイクルシステムは、図1に示した要素機器の他に、内部熱交換器、乾燥器(ドライヤ)、液分離器、油回収器、及び不凝縮ガス分離器を備えていてもよい。
(a)熱交換器(蒸発器)内で液体状態の作動媒体を被冷却流体(空気、水など)と熱交換させ、気化させる。
(b)熱交換器から気化した作動媒体を取り出し、気化した作動媒体を圧縮機に通し、高圧の過熱蒸気を供給する。
(c)圧縮機から出た作動媒体を凝縮器へ通し、気体状態の作動媒体を被加熱流体(空気、水など)と熱交換させ、液化させる。
(d)液化した作動媒体を膨張弁により絞り膨張させ、低圧の湿り蒸気を供給し、工程(a)へ再循環させる。
以下、本発明の実施形態に係る有機ランキンサイクルシステムについて説明する。図2は、本発明の実施形態に係る有機ランキンサイクルシステム200の一例を示す概略図である。本発明の実施形態に係る熱伝達媒体を有機ランキンサイクルシステム200の作動媒体として用いることにより、50℃以上200℃以下、又は80℃以上150℃以下の熱エネルギーを機械エネルギーへ変換することができる。
(a)熱交換器(蒸発器20)内で液体の作動媒体を被冷却流体(加熱源)と熱交換させ、気化(液体から気体へ相変化)させる。
(b)熱交換器から気化した作動媒体を取り出す。
(c)気化した作動媒体を膨張器(発電用タービン)22に通して膨張させ、機械的(電気的)エネルギーに変換する。
(d)膨張器から出た作動媒体を凝縮器へ通し、気体の作動媒体を凝縮(気体から液体への相変化)させる。
(e)液化した作動媒体を循環ポンプ23により昇圧するとともに移送して、工程(a)へ再循環させる。
ことが望ましい。環境負荷型の作動媒体の回収は、環境に対する負荷を軽減するために、フルオロカーボン冷媒を回収するときに用いられる回収装置を使用することが望ましい。環境負荷型の作動媒体を回収した後、本発明の実施形態に係る熱伝達媒体を充填する前に、有機ランキンサイクルシステムの作動媒体収容部を真空ポンプで減圧してもよい。熱伝達媒体の充填方法は、特に限定されないが、熱伝達媒体と有機ランキンサイクルシステムの圧力差を利用して充填してもよく、ポンプなどの機械的動力を利用して充填してもよい。
本実施形態では、第1実施形態で述べた共沸(様)組成物の種々の用途について説明する。
本発明の実施形態に係る共沸(様)組成物は優れた洗浄力を有する。本共沸(様)組成物を用いる洗浄の分野は特に限定されないが、これまでCFC-113(クロロトリフルオロメタン)、HCFC-141b(1,1-ジクロロ-1-フルオロエタン)、HCFC-225(3,3-ジクロロ-1,1,1,2,2-ペンタフルオロプロパン(HCFC-225ca)及び1,3-ジクロロ-1,1,2,2,3-ペンタフルオロプロパン(HCFC-225cb)の混合物)が洗浄剤として使用された分野が好適である。具体的には、電子部品(プリント基板、液晶表示器、磁気記録部品、半導体材料等)、電機部品、精密機械部品、樹脂加工部品、光学レンズ、衣料品等の洗浄や、自動車、二輪自動車、自転車、建機、農機、航空機、鉄道車両、船舶などの各種車両・乗物・輸送機関の洗浄(特にこれらのパーツクリーニングやブレーキクリーニング)が挙げられる。汚れの種類も限定されないが、CFC-113、HCFC-141b、HCFC-225で除去可能な汚れは、本共沸(様)組成物の組成比を最適化することで除去することが可能であり、そのような汚れとしてはパーティクル、油、グリース、ワックス、フラックス、インキ等が挙げられる。
本共沸(様)組成物を発泡剤として用いる場合について詳細に述べる。
本発明の実施形態に係る共沸(様)組成物はシリコーンの溶剤として非常に優れた特性を有する。即ち、本共沸(様)組成物は、オゾン層破壊係数及び地球温暖化係数が実質的にゼロで、不燃性であり、揮発性に優れ、かつ、種々のシリコーンを任意の割合で溶解させることができる。特に、本共沸(様)組成物は、広い共沸様組成範囲を持つので、各種のシリコーン化合物に応じた最適の組成を選定することができる。
本発明の実施形態に係る共沸(様)組成物は、不燃性であることから、エアゾール組成物の形態で用いることができる。本共沸(様)組成物を噴射器に高圧で充填し、噴射器から本共沸(様)組成物を噴射することができる。この時、本共沸(様)組成物に塗膜形成用組成物を混合させておくことで、塗膜形成用組成物を種々の物品の表面に塗布することができる。
本共沸(様)組成物に含まれるトランス-1-クロロ-3,3,3-トリフルオロプロペンや1-クロロ-1,3,3,3-テトラフルオロプロペンは、ともに蒸気圧が比較的低く、燃焼性を抑制するハロゲン、およびOHラジカルによって分解されやすい炭素-炭素二重結合を有する。このため、消火剤として利用することが可能である。本共沸(様)組成物を消火剤として用いる場合、不燃性化合物をさらに添加してもよい。不燃性化合物としては、窒素や二酸化炭素、希ガス、あるいは不燃性含フッ素化合物が挙げられる。不燃性含フッ素化合物としては、フルオロアルカン、フルオロアルケン、フルオロケトン、フルオロエーテルなどが挙げられる。
本共沸(様)組成物に含まれる1-クロロ-1,3,3,3-テトラフルオロプロペンは、無色透明の液体であり、不燃性であるとともに、燻蒸作用が高いことから、燻蒸剤としても使用することができる。このため、本共沸(様)組成物を噴霧器に充填し、害虫に対して本共沸(様)組成物を噴射させることで、効果的に害虫を駆除することができる。
