A method for providing a flow control system for an aircraft. A compressor is removed from an existing air cycle machine, along with compressor ducting that is connected to a primary stage outlet of the heat exchanger and a secondary stage inlet of the heat exchanger in the existing air cycle machine. A first connector duct is provided and connected to the primary stage outlet of the heat exchanger and the secondary stage inlet of the heat exchanger. The turbine is removed from the existing air cycle machine, and a second connector duct is provided and connected to the upstream turbine duct directly and the downstream turbine duct.

1. An environmental control system for an aircraft, comprising: a bleed air source;at least a first air cycle machine that has an air cycle inlet connected to the bleed air source and is operable to provide conditioned air to an air cycle outlet;at least a first flow control system that has a flow control inlet connected to the bleed air source and is operable to provide cooled air to a flow control outlet, wherein the first flow control system includes a heat exchanger that includes a primary stage and a secondary stage;a first connector duct that connects a primary stage outlet of the primary stage of the heat exchanger of the first flow control system to a secondary stage inlet of the secondary stage of the heat exchanger of the first flow control system without junctions or valves; anda mixing manifold that receives conditioned air from the air cycle machine and cooled air from the flow control system and is operable to selectively provide the cooled air, the conditioned air, or mixed air to the aircraft, wherein the mixing manifold produces the mixed air by mixing the cooled air and the conditioned air. 2. The environmental control system of claim 1, wherein the cooled air produced by the first flow control system is produced solely by heat exchange. 3. The environmental control system of claim 2, further comprising: the first air cycle machine including at least one turbine-compressor pair to produce conditioned air. 4. The environmental control system of claim 1, further comprising: at least a second flow control system connected to the mixing manifold, wherein the second flow control system produces cooled air solely by heat exchange. 5. The environmental control system of claim 1, further comprising: at least a second air cycle machine connected to the mixing manifold, the second air cycle machine including at least one turbine-compressor pair to produce conditioned air. 6. The environmental control system of claim 1, wherein the first flow control system does not include a turbine-compressor pair. 7. An environmental control system for an aircraft, comprising: a bleed air source;at least a first air cycle machine that has an air cycle inlet connected to the bleed air source and is operable to provide conditioned air to an air cycle outlet;at least a first flow control system that has a flow control inlet connected to the bleed air source and is operable to provide cooled air to a flow control outlet, wherein the first flow control system includes a heat exchanger that includes a primary stage and a secondary stage;a first connector duct connected to a primary stage outlet of the primary stage of the heat exchanger of the first flow control system and to a secondary stage inlet of the secondary stage of the heat exchanger of the first flow control system such that air travels from the primary stage outlet of the heat exchanger of the first flow control system directly to the secondary stage inlet of the heat exchanger of the first flow control system by way of the first connector duct, wherein the first connector duct connects the primary stage outlet of the primary stage of the heat exchanger of the first flow control system to the secondary stage inlet of the secondary stage of the heat exchanger of the first flow control system without junctions or valves; anda mixing manifold that receives conditioned air from the air cycle machine and cooled air from the flow control system and is operable to selectively provide the cooled air, the conditioned air, or mixed air to the aircraft, wherein the mixing manifold produces the mixed air by mixing the cooled air and the conditioned air. 8. An environmental control system for an aircraft, comprising: a bleed air source;at least a first air cycle machine that has an air cycle inlet connected to the bleed air source and is operable to provide conditioned air to an air cycle outlet using at least one turbine-compressor pair;at least a first flow control system that has a flow control inlet connected to the bleed air source and is operable to provide cooled air to a flow control outlet, wherein the first flow control system includes a heat exchanger that includes a primary stage and a secondary stage, and the cooled air produced by the first flow control system is produced solely by heat exchange at the heat exchanger;a first connector duct that connects a primary stage outlet of the primary stage of the heat exchanger of the first flow control system to a secondary stage inlet of the secondary stage of the heat exchanger of the first flow control system without junctions or valves; anda mixing manifold that receives conditioned air from the air cycle machine and cooled air from the flow control system and is operable to selectively provide the cooled air, the conditioned air, or mixed air to the aircraft, wherein the mixing manifold produces the mixed air by mixing the cooled air and the conditioned air. 9. The environmental control system of claim 8, further comprising: at least a second flow control system connected to the mixing manifold, wherein the second flow control system produces cooled air solely by heat exchange. 10. The environmental control system of claim 8, further comprising: at least a second air cycle machine connected to the mixing manifold, the second air cycle machine including at least one turbine-compressor pair to produce conditioned air. 11. The environmental control system of claim 8, wherein the first flow control system does not include a turbine-compressor pair.
