| Abstract: | 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. |
