Abstract
An environmental control system for conditioning a cabin of a vehicle positioned in an enclosed air-evacuated environment includes a first inlet for receiving a flow of a first medium, a second inlet for receiving a flow of a second medium, and a thermodynamic device fluidly coupled to both the first inlet and the second inlet. The thermodynamic device includes a compressor and at least one turbine operably coupled by a shaft. At least one conduit is fluidly coupled to the second inlet and bypasses the thermodynamic device. A mixing point is fluidly coupled to an outlet of the at least one turbine to the at least one conduit. A recirculation heat exchanger is fluidly coupled to an outlet of the thermodynamic device and to the at least one conduit at a location upstream from the mixing point.
