【Abstract】 The optimization analysis is presented in this paper for mixed-refrigerant Joule Thomson refrigerators operating in the cascade refrigeration temperature range including component selection and running parameters optimization. Meanwhile, a prototype is made and tested with two kinds of mixtures. Considered of its simplicity and reliability, the single throttling refrigeration system can take the place of the classical cascade refrigeration system in many cases.更多还原
