Abstract
An environmental control system includes a ram air circuit having a ram air duct and at least one ram heat exchanger arranged within the ram air duct, a compression device, and an expansion device. The compression device is configured to receive at least one of a first medium, a second medium, and a third medium. The environmental control system is operable in a plurality of modes including at least one normal mode and a failure mode. In the at least one normal mode, the first medium output from the compression device is exhausted into the ram air duct upstream from the at least one ram heat exchanger, and in the failure mode, only the third medium output from the compression device is exhausted into the ram air duct upstream from the at least one ram heat exchanger.
