Abstract

Circuito de refrigeración con por lo menos dos compresores (10a, 10b, 10c), comprendiendo cada compresor (10a, 10b, 10c) por lo menos un punto de lubricación que es un punto que resulta necesario lubricar durante el funcionamiento del compresor respectivo (10a, 10b, 10c), un cárter de aceite (20a, 20b, 20c) y por lo menos una bomba de aceite (12a, 12b, 12c) que presenta una salida para proporcionar aceite a dicho punto de lubricación; caracterizado por que la salida de la bomba de aceite (12a, 12b, 12c) de por lo menos uno de los compresores (10a, 10b, 10c) está conectada fluídicamente al punto de lubricación de por lo menos un compresor diferente (10a, 10b, 10c) de manera que el aceite suministrado por la bomba de aceite (12a, 12b, 12c) fluya hasta el cárter de aceite (20a, 20b, 20c) únicamente tras su paso por dicho por lo menos un punto de lubricación del compresor respectivo (10a, 10b, 10c).
