Helium Refrigeration and Liquefaction Using a Liquid Hydrogen Refrigerator for Precooling

reportActive / Technical Report | Accession Number: ADA286683 | Open PDF

Abstract:

Consideration is given to the use of a hydrogen refrigerator to assist in the production of temperatures below those obtained with hydrogen. A hydrogen refrigerator is used to maintain a precooling evaporator at or near 21 deg K in a helium gas circuit. The helium circuit may be arranged to produce liquid for external use or to produce refrigeration between 21 deg K and 4. 2 deg K in a closed system. Charts have been developed that show the requirements of the composite helium - hydrogen system and the effect of heat exchanger performance. The relative quantities of refrigeration hydrogen and helium at various temperature levels have been determined.
