An environmental control system pack is located downstream from and is fluidly coupled to the compressor outlet. The environmental control system pack includes a ram air circuit having at least one ram air heat exchanger. Another conduit for providing a second medium to the compressor fluidly couples an outlet of the at least one ram air heat exchanger and the compressor inlet.
