DESCRIPCIÓN
Fluido de transferencia de calor
La presente invención se refiere a composiciones que contienen hidrofluorolefinas y a su utilización como fluidos de transferencia de calor, agentes de expansión, disolventes y aerosoles.
Los problemas planteados por las sustancias que dañan la capa de ozono atmosférico (ODP: ozone depletion potencial) se trataron en Montreal, donde se firmó el protocolo que exige una reducción de la producción y de la utilización de los clorofluorocarburos (CFC). Este protocolo ha sido objeto de enmiendas que imponen el abandono de los CFC, y se ha extendido la reglamentación a otros productos, como los hidroclorofluorocarburos (HCFC).
La industria de la refrigeración y de la producción de aire acondicionado ha invertido mucho en la sustitución de estos fluidos refrigerantes, y es así como se han comercializado los hidrofluorocarburos (HFC).
Los (hidro)clorofluorocarburos utilizados como agentes de expansión o disolventes han sido sustituidos igualmente por los HFC.
En la industria automovilística, los sistemas de climatización de los vehículos comercializados en numerosos países se han pasado de un fluido refrigerante con clorofluorocarburo (CFC-12) al de hidrofluorocarburo (1,1,1,2- tetrafluoroetano: HFC-134a), menos nocivo para la capa de ozono. Sin embargo, con respecto a los objetivos fijados por el protocolo de Kyoto, el HFC-134a (potencial de calentamiento global, GWP = 1300) se considera como que tiene una capacidad de calentamiento elevada. La contribución al efecto invernadero de un fluido se cuantifica mediante un criterio, el potencial de calentamiento global (GWP, siglas en inglés de Global Warning Potentials), que resume la capacidad de calentamiento tomando un valor de referencia 1 para el dióxido de carbono.
El dióxido de carbono, siendo atóxico, ininflamable y con un GWP muy pequeño, se ha propuesto como fluido refrigerante de los sistemas de climatización reemplazando al HFC-134a. Sin embargo, el empleo de dióxido de carbono presenta muchos inconvenientes, principalmente ligados a la presión muy elevada de su puesta en práctica como fluido refrigerante en los aparatos y tecnologías existentes.
Por otra parte, la mezcla R-404A, constituida de 44% en peso de pentafluoroetano, 52% en peso de trifluoroetano y 4% en peso de HFC-134a es ampliamente utilizada como fluido de refrigeración de grandes superficies (supermercado) y en transportes frigoríficos. Esta mezcla tiene sin embargo un GWP de 3900. La mezcla R-407C, constituida de 52% en peso de HFC-134a, 25% en peso de pentafluoroetano y 23% en peso de difluorometano, se utiliza como fluido de transferencia de calor en el aire acondicionado y las bombas de calor. Esta mezcla tiene sin embargo un GWP de 1800.
El documento de patente JP 4110388 describe la utilización de los hidrofluoropropenos de fórmula CaHmFn, representando m, n un número entero comprendido entre 1 y 5 incluidos, y m + n = 6, como fluidos de transferencia de calor, en particular el tetrafluoropropeno y el trifluoropropeno.
