Title (EN) COMPOSITION CONTAINING REFRIGERANT AND APPLICATION OF SAID COMPOSTION
(FR) COMPOSITION CONTENANT UN AGENT RÉFRIGÉRANT ET APPLICATION DE LADITE COMPOSITION
(JA) 冷媒を含有する組成物及びその応用
Abstract:
(EN) The present invention provides a composition containing a refrigerant that, relative to R404A (R125/R134a/R143a = 44/4/52 wt%), has equivalent incombustibility and substitutable refrigeration capacity, and is also endowed with performance such that the COP is equivalent or greater and the GWP is 1500 or less. The present invention, specifically, provides a composition containing a refrigerant wherein the refrigerant contains a mixture of fluorinated hydrocarbons; the mixture contains difluoromethane (R32), pentafluoroethane (R125), and 1,1,1,2-tetrafluoroethane (R134a) in specific concentrations; the fluorinated hydrocarbons included in the mixture have a specific composition ratio; and the composition can be used as a substitute refrigerant for R22 or a substitute refrigerant for R404A.
(FR) La présente invention concerne une composition contenant un agent réfrigérant qui, par rapport au R404A (R125/R134a/R143a = 44/4/52 % en pds), présente une capacité de non-combustibilité et de réfrigération substituable équivalente, et est également dotée de performance telle que le coefficient de performance, COP, est supérieur ou égal et le potentiel de réchauffement climatique, GWP, est de 1 500 ou moins. La présente invention concerne, particulièrement, une composition contenant un agent réfrigérant, l’agent réfrigérant contenant un mélange d’hydrocarbures fluorés ; le mélange contient du difluorométhane (R32), du pentafluoroéthane (R125), et du 1,1,1,2-tétrafluoroéthane (R134a) en concentrations spécifiques ; les hydrocarbures fluorés compris dans le mélange présentent un rapport de composition spécifique ; et la composition peut être utilisée comme agent réfrigérant de substitution du R22 ou agent réfrigérant de substitution du R404A.
(JA) 本発明は、R404A(R125/R134a/R143a=44/4/52重量%)と比較して、同等の不燃性、代替可能な冷凍能力等を有し、COPが同等もしくはそれ以上であり、且つ、GWPが1500以下であるという性能を兼ね備える冷媒を含有する組成物を提供する。 本発明は、具体的には、冷媒を含有する組成物であって、前記冷媒が、フッ素化炭化水素の混合物を含有し、前記混合物が、ジフルオロメタン(R32)、ペンタフルオロエタン(R125)及び1,1,1,2-テトラフルオロエタン(R134a)を特定濃度で含有し、前記混合物に含まれるフッ素化炭化水素が、特定の組成比を有し、且つ、R22の代替冷媒又はR404Aの代替冷媒として用いられる、組成物を提供する。
