Abstract

There is worldwide interest in the development of mixed refrigerant cycle refrigerators and liquefies Most studies till date have been at temperatures greater than 70 K. However, there is a need for refrigerators working below 70 K for use in superconducting transformers, motors, generators and cables. In this paper we present a new process for a mixed refrigerant cycle refrigerator for use in superconducting applications.
