Abstract: An environmental control system of an aircraft includes a compressing device including a compressor and a turbine configured to receive a flow of first medium sequentially. The compressing device additionally includes a second turbine configured to receive a flow of second medium distinct from the first medium. A dehumidification system is arranged in fluid communication with the turbine and a bypass valve is configured to divert the flow of the first medium output from the compressor around the turbine.

Abstract: An airplane is provided. The airplane includes a pack. The pack includes a shaft, a compressor, and a turbine coupled to the compressor via the shaft. The turbine receives and expands a first medium to provide power to the compressor via the shaft. The compressor receives and compresses a second medium in accordance with the power provided by the turbine via the shaft. The turbine is fluidly coupled to a heat exchanger of an air conditioning system.

Abstract: A system is provided. The system includes a first environmental control sub-system, operating in a first mode, that receives a first medium at a first flow amount and a first pressure. The system also includes a second environmental control sub-system, operating in a second mode, that receives a second medium at a second flow amount and a second pressure. The first flow amount is greater than the second flow amount, and the second pressure is greater than the first pressure.

Abstract: A system includes a first inlet providing a medium from a source and a compressing device arranged in communication with the first inlet. The compressing device includes a compressor configured to receive the medium and a turbine located downstream from the compressor. The system additionally includes at least one heat exchanger and an electric motor operably coupled to the compressor. The system is powered by mechanical power from the medium and by electrical power from the electric motor. The input power of the electric motor is less than or equal to 0.5 kilowatts per pounds per minute of medium compressed.

Abstract: An environmental control system of an aircraft includes a ram air circuit including a ram air shell having a plurality of heat exchangers positioned therein, the plurality of heat exchangers including a first heat exchanger, a second heat exchanger, and a third heat exchanger. The ram air circuit is configured and arranged so that a first medium received at the first heat exchanger passes through the first heat exchanger and then through the third heat exchanger and so that a second medium received at the second heat exchanger passes through the second heat exchanger. A compressing device is arranged in fluid communication with the ram air circuit.
