摘要:
An environmental control system for conditioning a cabin of a vehicle positioned in an enclosed air-evacuated environment includes a first inlet (24) for receiving a first medium (A1), at least one inlet for receiving a second medium, and a thermodynamic device (30) including a compressor (32) and a plurality of turbines operably coupled by a shaft (34). The plurality of turbines includes a first turbine (36) and a second turbine (38) arranged in series relative to a flow of the first medium (A1). Energy extracted from the second medium at one of the plurality of turbines is used to drive the compressor (32). The flow of the first medium (A1) and a first flow of the second medium are mixed to form a third medium at a first mixing point (M1) located downstream from the thermodynamic device (30) relative to the flow of the first medium (A1).

An environmental control system for conditioning a cabin of a vehicle positioned in an enclosed air-evacuated environment includes a first inlet (24) for a first medium (A1), a second inlet (26) for a second medium (A2), 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 (A1) and a first flow of the second medium (A2) are mixed to form a third medium at a first mixing point (M1) arranged downstream from the thermodynamic device relative to the flow of the first medium (A1). A dehumidification system (40) is fluidly coupled to the thermodynamic device and is arranged upstream from the at least one turbine. A regeneration heat exchanger (60) is fluidly coupled to and is downstream from the compressor. Heat is removed from the first medium (A1) at the regeneration heat exchanger (60).
