Abstract
An air cycle machine for an environmental control system for an aircraft includes at least one turbine configured to receive and extract work from a first medium and a third medium. A compressor is configured to compress a second medium and a shaft mechanically couples the at least one turbine and the compressor. A mixing point is located downstream of at least one turbine. A mixture of the first medium and the third medium generated at the mixing point is provided to another component of the environmental control system.

An air cycle machine for an environmental control system for an aircraft, the air cycle machine comprising:
- at least one turbine configured to receive and extract work from a first medium and a third medium;
- a compressor configured to compress a second medium;
- a shaft mechanically coupling the at least one turbine and the compressor;
- a mixing point located downstream of the at least one turbine, wherein a mixture of the first medium and the third medium generated at the mixing point is provided to another component of the environmental control system;
- a ram air circuit having at least one ram air heat exchanger arranged therein, the at least one ram air heat exchanger being the another component of the environmental control system;
- and
- a divider arranged within the ram air circuit to form a first region and a second region, the at least one heat exchanger having a first portion arranged within the first region and a second portion arranged within the second region.
