Title
(DE) ARBEITSMEDIUM FÜR KÄLTEKREISLAUF UND KÄLTEKREISLAUFSYSTEM
(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) A working medium for a refrigeration cycle contains (A) 1,1,2-trifluoroethylene, (B) difluoromethane, and a disproportionation inhibitor, (C) a haloalkane (having 1 to 4 carbon atoms but excluding a case where one or more halogen atoms are all fluorine) as a disproportionation inhibitor. When a ternary phase diagram according to triangular coordinates represents mass-ratio composition of the components (A) to (C), the mass-ratio composition is within a composition range corresponding to a combined region formed of: a first overlapping region where a region a (more than 0 mass% and less than or equal to 65 mass% of the component (A)) and a region b (more than 0 mass% and less than or equal to 30 mass% of the component (B)) overlap one another; and a second overlapping region where a region c (more than or equal to 20 mass% and less than 100 mass% of the component (C)) and the region b overlap one another.
(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.
