Title
(EN) WORKING MEDIUM FOR REFRIGERATION CYCLE, AND REFRIGERATION CYCLE SYSTEM
(FR) FLUIDE ACTIF POUR CYCLE DE RÉFRIGÉRATION ET SYSTÈME À CYCLES DE RÉFRIGÉRATION

Abstract
(EN) This working medium for a refrigeration cycle contains (A) 1,1,2-trifluoroethylene, (B) difluoromethane, and (C) a haloalkane (excluding cases of C1-4 haloalkanes in which all of the halogen atoms are fluorine) as a disproportionation-suppressing agent. When the mass ratio compositions of components (A) through (C) are represented in a three-component composition diagram using triangular coordinates, the composition of the working medium is within the range of a composition corresponding to a synthesis region configured from: a first overlap region, in which a region a (where component (A) is greater than 0% by mass and no more than 65% by mass) and a region b (where component (B) is greater than 0% by mass and no more than 30% by mass) overlap; and a second overlap region, in which a region c (where component (C) is at least 20% by mass and less than 100% by mass) and the region b overlap.
(FR) Ce fluide actif pour un cycle de réfrigération se compose de (A) 1,1,2-trifluoroéthylène, de (B) difluorométhane et de (C) un haloalcane (à l'exclusion des cas d'haloalcanes C1-4 dans lesquels tous les atomes d'halogène sont du fluor) en tant qu'agent de suppression de dismutation. Lorsque les compositions de rapport de masse des composants (A) à (C) sont représentées dans un diagramme de composition à trois composants à l'aide de coordonnées triangulaires, la composition du fluide actif se situe dans la plage d'une composition correspondant à une région de synthèse configurée à partir de ce qui suit : une première région de chevauchement, dans laquelle une région a (où le composant [A] est supérieur à 0 % en masse et inférieur à 65 % en masse) et une région b (où le composant [B] est supérieur à 0 % en masse et inférieur à 30 % en masse) se chevauchent ; et une seconde région de chevauchement, dans laquelle une région c (où le composant [C] est d'au moins 20 % en masse et inférieur à 100 % en masse) et la région b se chevauchent.
(JA) 冷凍サイクル用作動媒体は、(A)1,1,2-トリフルオロエチレン、(B)ジフルオロメタン、不均化抑制剤の(C)ハロアルカン(炭素数1~4でハロゲン原子が全てフッ素の場合を除く)を含有する。(A)~(C)成分は、その質量比組成が三角座標による3成分組成図により表されたときに、領域a((A)成分が0質量%より大きく、かつ65質量%以下)と、領域b((B)成分が0質量%より大きく、かつ30質量%以下)とが重複する第一重複領域と、領域c((C)成分が20質量%以上、かつ100質量%未満)と、領域bとが重複する第二重複領域と、から構成される合成領域に対応する組成の範囲内である。
