Abstract

An environmental control system for conditioning a cabin of a vehicle positioned in an enclosed air-evacuated environment includes a first inlet for a first medium, a second inlet for a second medium, and a thermodynamic device including a compressor and at least one turbine. The at least one turbine is fluidly coupled to and arranged downstream from the first and second inlet. A flow of the first medium and a first flow of the second medium are mixed to form a third medium at a first mixing point arranged downstream from the thermodynamic device relative to the flow of the first medium. A dehumidification system is fluidly coupled to the thermodynamic device and is arranged upstream from the at least one turbine. A regeneration heat exchanger is fluidly coupled to and is downstream from the compressor. Heat is removed from the first medium at the regeneration heat exchanger.
