1. A system for a vehicle comprising:
a plurality of inlets for receiving a plurality of mediums, respectively;
a device arranged in fluid communication with at least a first inlet of the plurality of inlets, the first inlet configured to receive a flow of a first medium of the plurality of mediums, wherein the first medium is fresh air, the device comprising:
a shaft rotatable about a shaft axis;
a compressor connected to the shaft, the compressor being fluidly connected to a and configured to receive the flow of the first medium from the first inlet of the plurality of inlets;
a turbine connected to the shaft, wherein the turbine is fluidly connected to only the first inlet of the plurality of inlets such that only a first medium of the plurality of mediums is provided to a turbine inlet, the turbine being configured to drive the compressor using energy extracted from the first medium, wherein the turbine is a mixed-flow turbine and the turbine and the compressor are fluidly connected to the first inlet of the plurality of inlets in parallel;
a heat exchanger arranged downstream from an outlet of the compressor and from an outlet of the turbine, the heat exchanger having a first inlet fluidly connected to and configured to receive the flow of first medium from the compressor and the heat exchanger having a second inlet fluidly connected to and configured to receive the first medium from the outlet of the turbine.
