An environmental control system includes a turbomachine and an air cycle machine that is driven by shaft power of the turbomachine. The turbomachine includes a compressor, which supplies compressed bleed air to the air cycle machine. Ambient air is compressed by the compressor, and heat of compression is removed by an air-to-air heat exchanger, which envelops the turbomachine. The cooled, compressed air is expanded in the air cycle machine to produce a stream of cooled, conditioned air. Ambient air used by the air-to-air heat exchanger to cool the compressed bleed air is drawn into the turbomachine's exhaust by an eductor.
