EL CO2 COMO REFRIGERANTE COMPARACION DE PRESIONES CON OTROS REFRIGERANTES NATURALES El refrigerante R-744 o CO2 trabaja con altas presiones y por ello damos las siguientes tablas de Temperaturas de Saturación y sus respectivas presiones de Saturación para los refrigerantes R-170 (Etano), R-290(Propano), R-441a, R-600a (Isobutano), R-717 (Amoníaco) y R-744 (Dióxido de Carbono) para poder comparar las presiones de cada uno de ellos a las diferentes temperaturas. Las presiones positivas están en libras/pulg2 ó psig y las presiones negativas en pulgadas de mercurio o pulgadas de Hg. Para los refrigerante R-170 y R-744 no aparecen presiones arriba de 30°C aproximadamente y ello se debe a que se alcanzó el punto crítico de dichos refrigerantes. TIPO DE REFRIGERANTE (CLASE SEGURA)
