A home refrigerator can cool down to minus 18 degrees Celsius with the power of 100 watts. But if need to cool down to minus 271 degrees Celsius with the same power, it calls for the international advanced technology.

For many years, China's large-scale cryogenic refrigeration equipment depends on import and some special refrigeration equipment even unavailable. However, with the continuous development of related technologies in China, the situation has been significantly improved.

Recently, "The Development of large-scale cryogenic refrigeration system from the liquid helium to superfluid helium temperature zone", a national major project of scientific research equipment, passed acceptance and achievement evaluation marking that China has the ability to develop large-scale cryogenic refrigeration equipment with liquid helium temperature (minus 269 ℃) kilowatt level and superfluid helium temperature (minus 271 ℃) hundred watt level.
