A major scientific research project for developing a large-scale cryogenic refrigeration system in liquid helium to superfluid helium temperature range passed expert appraisal in April.

That means that China has the ability to develop large-scale cryogenic refrigeration equipment with a liquid helium temperature of -269 degrees Celsius kilowatt level and superfluid helium temperature of -271 degrees Celsius hundred-watt level.

The project was undertaken by the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences (TIPC-CAS).

Large-scale cryogenic refrigeration equipment from liquid helium to superfluid helium temperature range is indispensable in the aerospace industry, hydrogen energy storage and transportation, the development of helium resources, and other fields.
