Abstract

UN SISTEMA DE CIRCULACION REFRIGERANTE QUE USA UN REFRIGERANTE ALTAMENTE POLAR, COMO TIPIFICADO MEDIANTE UNA BASE HIDROFLUOROCARBONADO, Y UN ACEITE REFRIGERANTE QUE TIENE BAJA SOLUBILIDAD CON REFRIGERANTE LIQUIDO EN EL ASPECTO DE CONDENSACION. EL ACEITE TIENE UNA GRAVEDAD ESPECIFICA MAS GRANDE O MAS PEQUEÑA QUE EL REFRIGERANTE LIQUIDO. ESTO PUEDE PROPORCIONAR AISLAMIENTO ELECTRICO Y RESISTENCIA A LA HUMEDAD ALTOS, ACEITE BUENO REGRESA AL COMPRESOR (1), Y CON ALTO FIABILIDAD.
