Abstract

Et multitrinns kjølesystem er tilveiebragt. Kjølesystemet innbefatter et første kompresjonselement som frembringer en første komprimert kjølemiddelstrøm. En blander kombinerer den første komprimerte kjølemiddelstrømmen med en hjelpekjølemiddelstrøm. Et andre kompresjonselement er koblet til blanderen og frembringer en andre komprirnert kjølemiddelstrøm. En første varmeveksler mottar den andre komprimerte kjølemiddelstrømmen og genererer en avkjølet strøm. En strømsplitter mottar den avkjølte strøm og tilveiebringer første og andre utgangsstrømmer. En første ekspansjonsventil mottar den første utgangsstrømmen og styres flytende av den første utgangsstrømmen og en andre ekspansjonsventil mottar den andre utgangsstrømmen og styrer flyten av den andre utgangsstrømmen. En andre varmeveksler genererer hjelpekjølemiddelstrømmen som leveres til blanderen. En fordamper er koblet til den første ekspansjonsventilen og det første kompresjonselementet for å fordampe den første utgangsstrømmen og tilveiebringer en fordampet strøm til det første kompresjonselementet.
