Kompressionskreislauf eines Gasfluidums bei niedrigem Druck und Temperatur.

摘要

The compression circuit for a gaseous fluid, typically helium, which is present in a first container at a pressure lower than 20 hPa and a temperature lower than 4.2K is compressed by means of a plurality of compressors mounted in series, at least one heat exchanger being disposed in the chain of compressors and cooled through said fluid at a temperature higher than the temperature of the fluid in the first container, said fluid originating from a second fluid container which is associated with a refrigerating cycle. Application for example to devices for cooling supraconductor elements.
