Abstract
Une composition appropriée pour une utilisation dans des systèmes de réfrigération à température modérée ou basse existants ou nouveaux conçus pour fonctionner avec, ou appropriés pour utilisation avec, ou capable dêtre utilisé avec du HCFC-22 comme réfrigérant, la composition comprenant du difluorométhane (HFC-32), du pentafluoroéthane (HFC-125) et du tétrafluoroéthane (HFC134a), les trois composants étant présents dans la composition en quantités telles que la caractéristique de fonctionnement de la composition réfrigérante quant à la surchauffe est obtenue à un niveau acceptable et les caractéristiques de fonctionnement de la composition réfrigérante quant aux caractéristiques de capacité de refroidissement, de débit massique et defficacité (COP), lorsquutilisés en tant que réfrigérant dans un système de réfrigération à basse température, représentent chacun au moins 95 % des caractéristiques de fonctionnement du chlorodifluorométhane (HCFC-22) si le HCFC-22 devait être utilisé comme réfrigérant dans un tel système de réfrigération à basse température.
