Investigation on two-stage pulse-tube refrigeration with a helium and hydrogen mixtures.

Author(s) : GAN Z. H., CHENG Z. Z., CHEN G. B., et al.

Summary

An experimental investigation on two-stage pulse tube refrigeration with binary components of helium and hydrogen mixtures is presented. With the valves optimized at 20 K, the maximum gains in cooling power of 25% and COP of 31% at helium molar fraction 40% have been obtained near 20 K in the experiment.
