Abstract
An environmental control system of an aircraft, having a first flow circuit that transports a first flow to a cabin; a second flow circuit that transports a second flow away from the cabin and is fluidly separated from the first flow circuit; wherein the first flow circuit includes: a first compressor that is a cabin air compressor; an air cycle machine (ACM) downstream of the first compressor; and a primary heat exchanger between the first compressor and the ACM, and wherein the second flow circuit directs the second flow to the primary heat exchanger to condition the first flow prior to reaching the ACM.

An environmental control system of an aircraft, comprising
- a first flow circuit that transports a first flow to a cabin;
- a second flow circuit that transports a second flow away from the cabin and is fluidly separated from the first flow circuit;
- wherein the first flow circuit includes:
- a first compressor that is a cabin air compressor;
- an air cycle machine (ACM) downstream of the first compressor;
- and
- a primary heat exchanger between the first compressor and the ACM, and
- wherein the second flow circuit directs the second flow to the primary heat exchanger to condition the first flow prior to reaching the ACM.
