Air-cycle refrigeration systems ... are used in many modern commercial aircraft for air-conditioning the cabin. ... The compressed air, when expanded in an expander turbine, drops enough in temperature to be used to chill the cabin air. Such a system for aircraft is effective and lightweight because it makes use of air already compressed by the power compressors. 1, record 2, English, - air%2Dcycle%20refrigeration%20system
