Paper Abstract

Practical application of many low-temperature phenomena will demand capability for uninterrupted cryogenic cooling for periods of several years. The reversed Brayton turbo-refrigerator offers unmatched potential for satisfying this need. Life limitation due to wear is virtually eliminated through use of gas bearing turbo-machines for all dynamic components of the system. The turbo-refrigerator is suitable for cooling at temperatures down to liquid helium levels. The refrigerator concept is defined and the physical and operational characteristics are discussed. The input power, weight, and volume of turbo-refrigerator systems providing from 10 to 500 watts of cooling at temperatures from 10 to 100 K are presented, showing that performance of the turbo-refrigerator improves dramatically as the capacity increases.
