Abstract
A medium supply system for delivering one or more mediums to an environmental control system of a vehicle includes a manifold arranged in fluid communication with an inlet of the environmental control system, a first medium source for delivering a first medium to the manifold via a first port; a second medium source for delivering a second medium to the manifold via a second port, and a third medium source for delivering a third medium to the manifold via a third port. At least one of a temperature and pressure of each of the first medium, the second medium, and the third medium varies.
Claims13
A medium supply system for delivering one or more mediums to an environmental control system of a vehicle, the medium supply system comprising:
- a manifold having an outlet fluidly coupled to an inlet of the environmental control system;
- a first medium source for delivering a first medium to the manifold via a first port;
- a second medium source for delivering a second medium to the manifold via a second port, wherein the second medium source is an atmosphere surrounding the vehicle and the second medium is fresh air;
- and
- a third medium source for delivering a third medium connected to the manifold via a third port, wherein the first medium, the second medium, and the third medium are different and at least one of a temperature and pressure of each of the first medium, the second medium, and the third medium varies;
- wherein a mixture of at least two of the first medium, the second medium, and the third medium is provided at the outlet of the manifold.
An environmental control system of a vehicle, the environmental control system comprising:
- an environmental control system pack including:
- an inlet;
- a compression device including a compressor, a pneumatically driven energy source, and an electrically driven energy source;
- a ram air circuit including a ram air shell having at least one heat exchanger positioned therein;
- a dehumidification system arranged in fluid communication with the ram air circuit;
- and
- a medium supply system including a conduit arranged in fluid communication with a source of a first medium, a source of a second medium, and a source of a third medium, the first medium, the second medium, and the third mediums being different types of mediums, wherein at least two of the first medium, the second medium, and the third medium are mixed within the conduit and provided to the inlet of the environmental control system pack, wherein the at least two mediums includes the second medium and the second medium is a fresh air having a pressure generally equal to an ambient pressure outside of the vehicle.
