Abstract: Disclosed is a method of environmental control, comprising: passing a first air stream and a second air stream through a valve; wherein the valve directs the first air stream through a first adsorption bed and directs the second air stream through a second adsorption bed; wherein the first adsorption bed produces a dehumidified air stream, and wherein the second adsorption bed is purged of moisture by the second air stream, thus producing a purge stream; and using the valve to redirect the first air stream and the second air stream when the first adsorption bed reaches a moisture saturation point or a timed interval, wherein the first air stream passes through the second adsorption bed and the second air stream passes through the first adsorption bed.

Abstract: An airplane is provided. The airplane includes a motor-driven compressor assembly. The motor-driven compressor assembly includes a shaft, a motor, a compressor, and a turbine coupled to the compressor via the shaft. The motor provides a first power to the compressor via the shaft. The turbine receives and expands a second medium to provide a second power to the compressor via the shaft. The compressor receives and compresses a first medium in accordance with the first power provided by the turbine and the second power provided by the motor.
