Abstract

Mezcla refrigerante sustituta del diclorodifluorometano. Las mezclas refrigerantes de la presente invención presentan la composición R227ea (heptafluoropropano), R-134a (1,1,1,2- tetrafluoroetano), R-143a (1,1,1-trifluoroetano) y R-600a (isobutano) en las proporciones en peso 12-30 / 69-90 / 2-10 / 0- 3 respectivamente. Especialmente preferida es la composición en la que los compuestos R227ea, R-134a, R-143a y R-600a están presentes en las proporciones 12 / 80 / 5 / 3 respectivamente. Dichas mezclas encuentran utilización como sustituto directo del R-12 en sistemas de refrigeración comercial e industrial, en sistemas de aire acondicionado fijo y de automóvil, así como en bombas de calor.Substituted refrigerant mixture of dichlorodifluoromethane. The refrigerant mixtures of the present invention have the composition R227ea (heptafluoropropane), R-134a (1,1,1,2-tetrafluoroethane), R-143a (1,1,1-trifluoroethane) and R-600a (isobutane) in the proportions by weight 12-30 / 69-90 / 2-10 / 0-3 respectively. Especially preferred is the composition in which the compounds R227ea, R-134a, R-143a and R-600a are present in proportions 12/80/5/3 respectively. These mixtures find use as a direct substitute for R-12 in commercial and industrial refrigeration systems, in fixed and automobile air conditioning systems, as well as in heat pumps.
