摘要： 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.

摘要翻译： 在空气循环机中，涡轮机由发动机排放空气驱动，涡轮机动力机械地传递到压缩机以压缩发动机排出空气或露天空气。 如果需要，可以设置电动机来电动驱动压缩机，从而用作涡轮机动力的辅助动力。 空气循环机用于飞机的空调系统，其中通过利用由涡轮机动力驱动的压缩机用作通风空气，露天或发动机风扇的空气在其压力下升高。 因此，能够有效地降低能量消耗高的发动机排出空气。
