Abstract
A pressurization system for a vehicle includes an inlet for receiving a medium and a cabin air compressing device arranged in fluid communication with the inlet. The cabin air compressing device includes a shaft, a compressor connected to the shaft, a motor operably connected to the shaft and configured to drive the compressor, and a turbine connected to the shaft and also configured to drive the compressor upon receipt of the medium. A heat exchanger has a first inlet fluidly connected to the compressor outlet and a second inlet fluidly connected to the turbine outlet. The compressor inlet and the turbine inlet are fluidly connected to and are arranged in parallel relative to the inlet.
