In an air cycle machine, a turbine is driven by an engine bleed air, and the turbine power is mechanically transmitted to a compressor to compress the engine bleed air or open air. An electric motor may be provided to electrically drive the compressor, if necessary, to thereby serve as an auxiliary power for the turbine power. The air cycle machine is used for an air conditioning system for an aircraft, wherein open air or engine fan air is raised in its pressure by taking advantage of the compressor driven by the turbine power to use as a ventilation air. Therefore, a consumption of the engine bleed air having a high energy level can be efficiently reduced.
