ENVIRONMENTAL CONTROL SYSTEM MIXING CABIN DISCHARGE AIR WITH BLEED AIR DURING A CYCLE

摘要

A system and method that comprises an air cycle machine (240), a flow of bleed air, at least one heat exchanger (220), and an inlet (201) configured to supply the flow of the bleed air is provided. The bleed air flows from a source to mix with recirculated air in accordance with a high pressure mode or a recirculation chilling mode. The system and method can also utilize the recirculated air flowing from the chamber (202) to drive or maintain the air cycle machine (240) in accordance with the above modes.
