Abstract
Official abstract text for this publication.
A system, which includes a plurality of heat exchangers and a compressing device, is configured to prepare in parallel a medium bled from a low-pressure location of an engine and flowing through a plurality of heat exchangers into a chamber. The compressing device is in communication with the plurality of heat exchangers and regulates a pressure of the medium flowing through the plurality of heat exchangers.
First claim
Opening claim text (preview).
What is claimed is: 1. A system, comprising: a medium flowing from a low-pressure location of an engine to a chamber; a plurality of heat exchangers; a valve located upstream from the plurality of heat exchangers, the valve configure to divide in parallel the medium across at least a first heat exchanger and a second heat exchanger of the plurality of heat exchangers, wherein the system operates in a heat exchanger cooling mode that lowers a pressure of the medium near that of a chamber pressure by combining a flow of the medium exiting out of the secondary heat exchanger and a flow of the medium exiting out of the first heat exchanger through an activation of a second valve that forwards the flow of the medium exiting out of the first heat exchanger; and a compressing device, in communication with the plurality of heat exchangers, configured to regulate a pressure of the medium, wherein the medium bypasses the compressing device when the valve divides in parallel the medium across at least the first heat exchanger and the second heat exchanger. 2. The system of claim 1 , wherein a first temperature of the medium at the valve is reduced when the medium flows across the first heat exchanger and the second heat exchanger in parallel to a second temperature. 3. The system of claim 2 , wherein ram air cooling provides sufficient energy to the plurality of heat exchangers to reduce the first temperature to the second temperature. 4. The system of claim 1 , wherein a pressure of the medium at the low-pressure location of an engine is slightly above the chamber pressure. 5. The system of claim 1 , wherein the system is an environmental control system of an aircraft, wherein the medium is air bled from an engine of the aircraft, and wherein the chamber is a cabin of the aircraft.
