Abstract
(EN)
A non-azeotropic refrigerant composition is described which comprises (A) at least one compound selected from the group consisting of carbon dioxide and fluoromethane, (B) at least one compound selected from the group consisting of the hydrofluorocarbons and the hydrofluorocarbon ethers, and (C) at least one hydrocarbon. The boiling point of component (B) is at least 15 °C higher than the sublimation temperature of the carbon dioxide and/or the boiling point of the fluoromethane making up component (A).
(FR)
L'invention concerne une composition réfrigérante comprenant (A) au moins un premier composé sélectionné dans le groupe comprenant le dioxyde de carbone et le fluorométhane, (B) au moins un composé sélectionné dans le groupe comprenant les hydrofluorocarbones et les éthers d'hydrofluorocarbone, et (C) au moins un hydrocarbone. Le point d'ébullition du composant (B) est supérieur d'au moins 15 °C à la température de sublimation du dioxyde de carbone et/ou au point d'ébullition du fluorométhane faisant partie du composant (A).
