I think Carnot cycle is the answer.

Air can also be liquefied by Claude's process in which the gas is allowed to expand isentropically twice in two chambers. While expanding, the gas has to do work as it is led through an expansion turbine. The gas is not yet liquefied, since it would destroy the turbine. Final liquefaction takes place by isenthalpic expansion in a Joule-Thomson-Valve.
