A system and method that comprises an air cycle machine, a flow of bleed air, at least one heat exchanger, and an inlet configured to supply the flow of the bleed air is provided. The bleed air directly flows from a source to either a compressor of the air cycle machine or the at least one heat exchanger in accordance with a high pressure, low pressure, or pressure boost operation mode. The system and method also can also utilize recirculated air flowing from the chamber to drive or maintain the air cycle machine in accordance with the above modes.


1. An environmental control system, comprising: an air cycle machine comprising a compressor, a shaft, and a turbine;an inlet configured to receive a flow of bleed air from an engine;a flow path between the inlet and the compressor that supplies the flow of the bleed air directly to the compressor of the air cycle machine to provide a lowest possible pressure drop for the bleed air;a heat exchanger;a high pressure water separator configured to condition the bleed air before the bleed air is passed to a chamber; anda quench loop connecting an exhaust of t...
