Cryogenic Refrigeration Concepts Utilizing Adsorption Pumping in Zeolites

  • W. H. Hartwig
Part of the Advances in Cryogenic Engineering book series (ACRE, volume 23)


Refrigeration without lubrication, vibration, and noise has heretofore been accomplished in at least three distinct forms; thermoelectric junctions that pump heat across a semiconductor PN junction [1], ammonia-water systems that remove heat in an adsorption-percolation-condensation-evaporation cycle [2], and chemisorption systems that exchange hydrogen from lanthanum-nickel and other metal hydrides to develop a pressure difference for circulation of hydrogen gas in a 20-K refrigerator [3,4]. While technically sound, these systems have a mix of advantages and disadvantages that render them unsuitable as the basis for complete cryogenic refrigeration cycles.
