since the entire
amount of gas is
available for the
actual refrigeration
process. Furthermore,
in comparison to static
gas bearings, leakage flow
of warm gas into the expansion
stage of the turbine is
eliminated. The dynamic gas
bearing-supported turbine is
thus characterized by an outstanding
low heat inleak. Compared to
oil bearings, dynamic gas bearings
eliminate
the risk of oil contamination
of the process gas.
