China's large-scale cryogenic refrigeration technology, which is fundamental for important industrial sectors such as aerospace and hydrogen energy, has made a major breakthrough, with the ability to cool down -271C with hundred-watt level power.
China's major scientific research project for developing the large-scale cryogenic refrigeration system in liquid helium to superfluid helium temperature range has passed experts' appraisal, Xinhua reported on Saturday. This project is supported by the Ministry of Finance and undertaken by the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences (TIPC-CAS).
China can now develop large-scale cryogenic refrigeration equipment with a liquid helium temperature of 4.2K (-269 C) kilowatt level and superfluid helium temperature of 2K (-271C) hundred-watt level, a milestone which has broken technology monopoly by the developed countries, and made China's large-scale cryogenic refrigeration technology reach the global advanced level, according to TIPC-CAS's official website.
