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

History In 1857, Siemens introduced the regenerative cooling concept with the Siemens cycle.Charles William Siemens, "Improvements in refrigerating and producing ice, and in apparatus or machinery for that purpose", British patent no. 2064 (filed: July 29, 1857). In 1895, William Hampson in EnglandW. Hampson, "Improvements relating to the progressive refrigerating of gases", British patent 10,165 (filed: May 23, 1895). and Carl von Linde in GermanyLinde, Carl, "Verfahren zur Verflüssigung atmosphärischer Luft oder anderer Gase" (Method for the liquefication of atmospheric air or other gases), German patent 88,824 (filed: June 5, 1895). independently developed and patented the Hampson–Linde cycle to liquefy air using the Joule–Thomson expansion process and regenerative cooling.Hydrogen through the Nineteenth Century On 10 May 1898, James Dewar used regenerative cooling to become the first to statically liquefy hydrogen.
