Thermodynamic efficiency in deep cooling of solids.

Author(s) : OTA J.

Summary

Deep cooling of solids for the purpose of fragmentation is based above all on the application of liquid nitrogen. It has been found that the economy of such systems can be improved by means of a modified temperature pull-down method based on a thermodynamic evaluation of energy spent for precooling and final deep cooling of solids. Presented calculation results concern two temperature pull-down processes giving substantially different temperature pull-down rates.
