An environmental control system for a vehicle comprising:
- at least one cabin air compressing device including a compressor having a compressor inlet and a compressor outlet;
- an environmental control system pack located downstream from and fluidly coupled to the compressor outlet via at least one conduit, the environmental control system pack including a ram air circuit;
- and
- a bypass conduit fluidly coupling the compressor outlet to the ram air circuit.
A method of operating an environmental control system of a vehicle, the method comprising:
- providing a medium to a compressor inlet of a compressor of at least one cabin air compressing device via a conduit;
- compressing the medium at the compressor to produce a compressed medium;
- providing a first portion of the compressed medium from a compressor outlet to an environmental control system pack;
- and
- exhausting a second portion of the compressed medium provided at the compressor outlet to a ram air circuit of the environmental control system pack.
