Abstract

Die Vorrichtung zum Verflüssigen von Heliumgas ent­ hält eine Vorkühlstufe (I) und eine weitere Kühlstufe (II), in dem das Hochdruckgas der Vorkühlstufe (I) in zwei Teilströ­ me aufgeteilt wird. Der erste Teilstrom (14) entspannt ar­ beitsleistend in eine Expansionsmaschine (15) auf einen ersten Zwischendruck, der zweite Teilstrom durchläuft ei­ nen Wärmeaustauscher (2). Beide Teilströme (13, 16) durch­ laufen danach gleichzeitig, aber getrennt einen dritten Wär­ meaustauscher (3). Der aus dem dritten Wärmeaustauscher (3) austretende zweite Teilstrom (21) entspannt arbeitslei­ stend in einer zweiten Expansionsmaschine (22) auf einen zweiten Zwischendruck. Beide Teilströme (17′, 23) durch­ laufen danach gleichzeitig, aber getrennt voneinander ei­ nen fünften Wärmeaustauscher (5) und von dort je ein Dros­ selventil (19 bzw. 25). Das mindestens teilweise verflüssigte Gas wird einem Kälteverbraucher (20) zugeführt. Der ther­ modynamische Wirkungsgrad der Vorrichtung ist größer als bei einer bekannten Vorrichtung.
