Abstract
An environmental control system (ECS) of an aircraft includes an inlet for a first medium, an outlet for the first medium, an air cycle machine including a compressor, a turbine, and a shaft operably coupling the compressor and the turbine, and a plurality of heat exchangers arranged in fluid communication with the air cycle machine. A first heat exchanger of the plurality of heat exchangers is arranged directly downstream from the turbine and heat is transferred to the first medium within the first heat exchanger. A water extractor is arranged directly downstream from the first heat exchanger and a flow path connects the air cycle machine, the plurality of heat exchangers, and the water extractor with the inlet and the outlet.
