【発明の詳細な説明】 冷媒として有用な組成物 本発明は一般に冷却及び加熱用途用の冷媒組成物及びか−る組成物の伝熱装置で の使用に関する。更に詳しく言えば、本発明はジクロロジフルオロメタン（冷媒 Ｒ−１２）及びジクロロジフルオロメタンと １．１−ジフルオロエタン（冷媒 Ｒ−１５２ａ）との共沸混合物（共沸物は冷媒Ｒ−５００である）に取って代わ るように意図された冷媒組成物に関する。[Detailed description of the invention] Compositions useful as refrigerants The present invention generally relates to refrigerant compositions for cooling and heating applications and heat transfer devices for such compositions. Regarding the use of. More specifically, the present invention utilizes dichlorodifluoromethane (refrigerant). R-12) and dichlorodifluoromethane and 1,1-difluoroethane (refrigerant R-152a) (the azeotrope is the refrigerant R-500) refrigerant compositions intended to be used.
機械的な冷却系及び関連ある伝熱装置例えばヒートポンプ及び空調システムは周 知である。か＼る装置において、適当な沸点を有する冷媒液体は低圧で蒸発して 周囲帯域から熱を奪い取る。得られる蒸気は次いで圧縮され、凝縮器に通送され そこで蒸気は凝縮し、別の帯域に熱を放出し、凝縮液は膨張弁を通って蒸発器に 返送され、こうして作業周期（サイクル）を完了する。蒸気を圧縮させ且つ凝縮 液をポンプ輸送するのに必要とされる機械的エネルギーはモーター又は内燃機関 によって提供し得る。Mechanical cooling systems and associated heat transfer devices such as heat pumps and air conditioning systems It is knowledge. In such equipment, a refrigerant liquid with a suitable boiling point is evaporated at low pressure. Removes heat from the surrounding area. The resulting vapor is then compressed and passed to a condenser There, the steam condenses and releases heat to another zone, and the condensate passes through an expansion valve to the evaporator. It is sent back, thus completing the work cycle. Compress and condense steam The mechanical energy required to pump the liquid is provided by a motor or internal combustion engine. It can be provided by
適当な沸点と高い気化潜熱とを存するのに加えて、冷媒に好ましい特性とは、低 毒性、不燃性、無腐蝕性、高安定性及び不快臭のないことが挙げられる。In addition to having a suitable boiling point and high latent heat of vaporization, desirable properties for refrigerants include low These include toxicity, non-flammability, non-corrosion, high stability and no unpleasant odor.
これまで、伝熱装置は十分に及び部分的にハロゲン化したクロロフルオロカーホ ン冷媒例えばジクロロジフルオロメタン（冷媒Ｒ−１２）及びクロロジフルオロ メタン然しなから、近年十分に及び部分的にハロゲン化したクロロフルオロカー ボンは地球の保護オゾン層に損傷を与えてしまうという国際的な関心か増大しつ つあり、該クロロフルオロカーホンの製造及び使用は厳格に制限すべきてあり最 終的には完全に失くしてしまうという一般的な合意かある。Until now, heat transfer devices have been made using fully and partially halogenated chlorofluorocarbons. Refrigerants such as dichlorodifluoromethane (Refrigerant R-12) and chlorodifluoromethane (Refrigerant R-12) Since methane has recently become a fully and partially halogenated chlorofluorocarbon, There is growing international concern that Bonn is damaging the Earth's protective ozone layer. Therefore, the production and use of chlorofluorocarbons should be strictly restricted and There is a general consensus that eventually we will lose it completely.

オゾン涸渇の可能性に加えて、大気中に有意な濃度のクロロフルオロカーホン冷 媒か存在すると地球の温暖化（言わゆる温室効果）に寄与すると示唆されている 。それ故、ヒドロキシル基の如き別の大気中の成分と反応する能力がある結果と して、比較的短かい大気中の寿命を有する冷媒を用いるのか望ましい。In addition to the potential for ozone depletion, significant concentrations of chlorofluorocarbons in the atmosphere It has been suggested that the presence of pollutants contributes to global warming (the so-called greenhouse effect). . Therefore, the result is the ability to react with other atmospheric components such as hydroxyl groups. Therefore, it is desirable to use a refrigerant that has a relatively short atmospheric lifetime.
