摘要
本文提出了利用内复叠节流制冷循环获得３０Ｋ－６０Ｋ温区的新制冷方案。进行了与之相关的热力学问题分析，建立了实验装置，首次获得了５０Ｋ左右的低温。
A new thermodynamic process for obtaining the temperature range from 30K to 60K was proposed based on the auto-cascade mixed-refrigerant refrigeration (AMR) cycle. An experimental set-up was made to verify the proposed thermodynamic cycle. In the experiment, a no-load temperature of around 50K was achieved successfully.
