20 K Helium Refrigerator
Essential Core Equipment for Basic Science & Energy Security
The 20K helium refrigerator adopts a helium turbine reverse Brayton refrigeration cycle to obtain 20K refrigeration capacity. The obtained cold helium gas below 20K is returned to the cold box after cooling the user equipment. The main equipment includes: compressor, oil filter, 20K cold box, control system, helium buffer tank, etc. The 20K cold box is a vacuum adiabatic cold box, and the cold box contains a multistage heat exchanger, turbine expansion machine, internal adsorber, low-temperature valves, measuring elements and other components.
