Summary

ADSORPTION CRYOCOOLERS CAN BE COMBINED IN CASCADE REFRIGERATION SYSTEMS TO PRODUCE TEMPERATURES LOWER THE PAPER DESCRIBES HOW THE PERFORMANCE OF GAS ADSORPTION CRYOCOOLERS CAN BE GREATLY IMPROVED BY USING ADSORBENTS WITH LOW VOID VOLUME WITHIN AND BETWEEN INDIVIDUAL ADSORBENT PARTICLES, REDUCING VOID VOLUMES IN PLUMBING LINES, AND BY COMPRESSING THE WORKING FLUID IN MORE THAN ONE STAGE. AN ANALYTICAL MODEL WAS USED. OPERATING PRESSURE OPTIMIZATION CURVES FOR 80 AND 117,5 K CHARCOAL/NITROGEN ADSORPTION CRYOCOOLERS ARE ALSO PRESENTED, FOR BOTH SINGLE-STAGE AND MULTISTAGE COMPRESSOR SYSTEMS.
