A Refrigeration System Incorporating a Low-Capacity, High-Speed, Gas-Bearing-Supported Expansion Turbine
The purpose of this report is to describe the application of previously developed gas-bearing principles [1,2,3] to a turbine expander operating as part of a small-capacity helium refrigeration system. This refrigeration system, chosen for its simplicity, uses helium gas as the refrigeration medium and bearing supply, and is capable of providing a continuous refrigeration sink at 4.2°K.
