Title (EN) REFRIGERANT MIXTURE OF DIMETHYL ETHER AND CARBON DIOXIDE
(FR) MELANGE REFRIGERANT D’ETHER DE DIMETHYLE ET DIOXYDE DE CARBONE
(JA) ジメチルエーテルと二酸化炭素の混合物冷媒
Abstract: front page image
(EN)Disclosed is a safe, non-toxic refrigerant exhibiting excellent performance which is obtained by mixing dimethyl ether and carbon dioxide as refrigerants. This refrigerant does not deplete the ozone layer, and has an extremely low global warming potential. Specifically disclosed is a refrigerant composition for freezers which is characterized by containing 90-40 mol% of dimethyl ether and 10-60 mol% of carbon dioxide based on the total mole number of the dimethyl ether and carbon dioxide.
(FR)Il est prévu un réfrigérant inoffensif, non toxique aux excellentes performances que l’on obtient en mélangeant de l’éther de diméthyle et du dioxyde de carbone comme réfrigérants. Ce réfrigérant n’épuise pas la couche d’ozone et présente un potentiel de réchauffement de la planète extrêmement bas. Il est prévu spécifiquement une composition réfrigérante pour congélateurs, caractérisée en ce qu’elle contient de 90 à 40 % molaire d’éther de diméthyle et de 10 à 60 % molaire de dioxyde de carbone sur la base du nombre molaire total de l’éther de diméthyle et du dioxyde de carbone.
(JA)【課題】 冷媒としてジメチルエーテルと二酸化炭素とを混合し、オゾン層を破壊しない、地球温暖化係数の極めて小さい安全で毒性のない優れた性能を有する冷媒を提供する。 【解決手段】 ジメチルエーテルと二酸化炭素の総モル数を基準として、ジメチルエーテルを90モル%~40モル%、二酸化炭素を10~60モル%含有することを特徴とする冷凍機用冷媒組成物。
