Abstract

Un sistema de refrigeración de CO2 incluye una pluralidad de compresores configurados para circular un refrigerante de CO2, una línea de succión configurada para suministrar el refrigerante de CO2 a los compresores, un separador de aceite configurado para separar aceite del refrigerante de CO2, y una línea de retorno de aceite configurada para suministrar el aceite del separador de aceite a la línea de succión; el aceite se mezcla con el refrigerante de CO2 en la línea de succión antes de alcanzar los compresores.
