Summary:PROBLEM TO BE SOLVED: To provide refrigerant compositions that do not deplete the ozone layer, that do not cause unwanted levels of global warming and that at the same time satisfy all of other stringent requirements of such systems for materials used as heat transfer materials.SOLUTION: A heat transfer composition comprises: (a) a first component comprising difluoromethane (R-32); (b) a second component selected from C2-C5 multifluorinated olefins; (c) and optionally at least one third component selected from C2-C3 fluorinated alkanes, CF3I, and combinations of these.SELECTED DRAWING: None 【課題】オゾン層を破壊せず、不必要なレベルの地球温暖化の原因とならず、同時に、熱移動媒体として使用される材料についてかかる系の他の厳しい要求をすべて満たす冷媒組成物の提供。【解決手段】（ａ）ジフルオロメタン（Ｒ−３２）を含む第一の成分；（ｂ）多フッ素化されたＣ２〜Ｃ５のオレフィンから選択される第二の成分；及び（ｃ）場合により、フッ素化されたＣ２〜Ｃ３のアルカン、ＣＦ３Ｉ、及びこれらの組合せから選択される少なくとも１種の第三の成分を含む熱伝達組成物。【選択図】なし
