In an air cycle system, the cold air used for air conditioning is produced due to what phenomenon?

Explanation:
Cold air in an air cycle system comes from the cooling that occurs when compressed air expands through a turbine. As the high-pressure air expands, it does work on the turbine blades, converting some of the gas’s enthalpy into shaft work, and its temperature drops. This expansion cooling is what provides the chilly air used for cabin conditioning. Heat exchangers ahead of the turbine mainly pre-cool the air, but the significant temperature drop that produces the cold supply comes from the expansion in the turbine.
