Abstract
An environmental-control-system (ECS) for delivering ECS supply air to a cabin having: a first mixer that receives the ECS supply air; a first vapor-cycle-system (VCS) coupled to the first mixer and includes: a first working fluid; a first compressor; a first condenser; a first turbine that is a flash-liquid-expander (FLE) turbine, that receives the first working fluid as a liquid and outputs the first working fluid as a two-phase mixture; a first interconnecting shaft coupling the first compressor and the first turbine; a first evaporator; a second mixer; a bypass connected in parallel with the first VCS, between the first mixer and the second mixer; and in predetermined operational conditions: the first mixer directs the ECS supply air to the second mixer via one or both of the first VCS and the bypass; and the second mixer directs the ECS supply air to the cabin.
