Abstract (en)
[origin: WO9704278A1] A process and device are proposed for generating low temperatures using low-boiling gases. Circulating gas is compressed to high pressure by a compressor (1), cooling is done by expansion machines (14), and high-pressure gas cools by releasing its heat in the counterflow heat exchanger (17) while low-pressure gas is heated by heat absorption in the counterflow heat exchanger. At least one component current in part of the circulation undergoes simultaneous work-performing expansion and recuperative heat exchange in the same device (14).
