Abstract

LA PRESENTE INVENCION SE REFIERE A MEZCLAS REFRIGERANTES QUE SUSTITUYEN AL CLORODIFLUOMETANO (HCFC-22). LAS MEZCLAS DE LA PRESENTE INVENCION TIENEN UNAS CARACTERISTICAS DE REFRIGERACION SIMILARES A LAS DEL HCFC-22. LAS MEZCLAS CONTIENEN DE UN 10 APROXIMADAMENTE A UN 90 POR CIENTO EN PESO APROXIMADAMENTE DE UN PRIMER COMPONENTE SELECCIONADO DEL GRUPO QUE CONSISTE EN 1,1,1-TRIFLUORETANO, DIFLUOMETANO, PROPANO Y UNA MEZCLA DE LOS MISMOS; DE UN 1 APROXIMADAMENTE A UN 50 POR CIENTO EN PESO APROXIMADAMENTE DE UN SEGUNDO COMPONENTE SELECCIONADO DEL GRUPO QUE CONSISTE EN UN HIDROFLUOCARBURO QUE TIENE DE 1 A 3 ATOMOS DE CARBONO, FLUOCARBURO QUE TIENE DE 1 A 3 ATOMOS DE CARBONO, UN COMPUESTO INORGANICO Y MEZCLAS DE LOS MISMOS QUE TIENE UN PUNTO DE EBULLICION A PRESION ATMOSFERICA QUE VA DE -90 GRADOS C APROXIMADAMENTE A MENOS DE -50 GRADOS C; Y DE UN 1 APROXIMADAMENTE A UN 50 POR CIENTO EN PESO APROXIMADAMENTE DE UN TERCER COMPONENTE QUE ES UN HIDROFLUOCARBURO QUE TIENE DE 1 A 3 ATOMOS DE CARBONO, DISTINTO DEL 1,1,1-TRIFLUORETANO, QUE TIENE UN PUNTO DE EBULLICION A TEMPERATURA ATMOSFERICA QUE VA DE -50 GRADOS C APROXIMADAMENTE A -10 GRADOS C APROXIMADAMENTE. LAS COMPOSICIONES REFRIGERANTES TIENEN UNA PRESION DE VAPOR SUSTANCIALMENTE IGUAL A LA PRESION DE VAPOR DEL HCFC-22.
