Regenerative cooling

Regenerative cooling

Regenerative cooling is a method of cooling gases in which compressed gas is cooled by allowing it to expand and and thereby taking heat from the surroundings, the cooled expanded gas then passes through a heat exchanger where it cools the incoming compressed gas.

Regenerative cycles

*Stirling cycle
*Gifford-McMahon
*Vuillemier
*Pulse tube refrigerator

History

1857 - Siemens introduced the Regenerative cooling concept with the Siemens cycle, in 1895 independent from each other William Hampson in England and Carl von Linde in Germany obtained patents for equipment to liquefy air using tile Joule Thomson expansion process and regenerative cooling [ [http://history.nasa.gov/SP-4404/app-a1.htm Hydrogen through the Nineteenth Century] ] On 10 May 1898, James Dewar used regenerative cooling to become the first to statically liquefy hydrogen.
