Air cycle air conditioning system for vehicles
 Air at substantially ambient pressure is cooled in a heat exchanger and introduced into an enclosure for cooling. The air is withdrawn from the enclosure and a portion of the air is expanded through a turbine for additional cooling and passed through the heat exchanger for the removal of heat therefrom. The air is then compressed to substantially ambient pressure and expelled. Additional cooling of the expanded air from the turbine may be obtained by evaporating a fluid therein. The fluid may be water condensed in, and withdrawn from, the heat exchanger.
