Abstract

An environmental control system of a vehicle includes a compressor having a compressor inlet configured to receive a first medium and a compressor outlet. A compressed first medium is provided at the compressor outlet. A conduit is configured to receive a second medium and a heat exchanger is mounted to the compressor. The heat exchanger is fluidly connected to a portion of the compressor and to the conduit.

Claims (27)

1 . An environmental control system of a vehicle comprising:

a compressor having a compressor housing including a compressor inlet configured to receive a first medium, and a compressor outlet, wherein a compressed first medium is provided at the compressor outlet, a rotating portion arranged within the compressor housing, and a volute formed within the compressor housing;

a conduit configured to receive a second medium; and

a heat exchanger mounted to the compressor housing at a location between the compressor outlet and one of the rotating portion and the volute, wherein the heat exchanger is fluidly connected to a portion of the compressor and to the conduit.

2 . The environmental control system of claim 1 , wherein the heat exchanger is integrally formed with the compressor housing.

3 . The environmental control system of claim 1 , wherein the heat exchanger further comprises a plate and at least one fin extending from the plate.

4 . The environmental control system of claim 3 , wherein the at least one fin includes a plurality of first fins, the plurality of first fins being arranged within the compressor housing.

5 . The environmental control system of claim 4 , wherein the at least one fin further comprises a plurality of second fins, the plurality of second fins being arranged within the conduit.

6 . The environmental control system of claim 3 , wherein the at least one fin includes a plurality of second fins, the plurality of second fins being arranged within the conduit.

7 . The environmental control system of claim 1 , wherein the compressor is part of a cabin air compressor.

8 . The environmental control system of claim 1 , wherein the compressor is part of a thermodynamic device.

9 . The environmental control system of claim 1 , wherein the first medium is fresh air.

10 . The environmental control system of claim 1 , wherein the second medium is cabin air.

11 . The environmental control system of claim 1 , wherein the vehicle is an aircraft.

12 . A method of operating an environmental control system of a vehicle comprising:

compressing a first medium at a compressor to form a compressed first medium;

extracting energy from a second medium at a turbine; and

heating the second medium within a heat exchanger using the compressed first medium, wherein the heating the second medium occurs prior to the extracting energy from the second medium, the compressor having a compressor housing, a rotating portion arranged within the compressor housing, and a volute formed within the compressor housing, the heat exchanger being mounted to the compressor housing at a location between the compressor outlet and one of the rotating portion and the volute.

13 . The method of claim 12 , wherein the first medium is fresh air.

14 . The method of claim 12 , wherein the second medium is cabin air.

15 . The method of claim 12 , further comprising providing the compressed first medium to an environmental control system pack, the environmental control system pack being located downstream from the compressor relative to a flow of the first medium.

16 . The method of claim 12 , further comprising providing the first medium to an environmental control system pack, wherein the compressor is part of the environmental control system pack.

17 . The method of claim 12 , wherein the vehicle is an aircraft.

18 . An environmental control system of a vehicle comprising:

a compressor having a compressor housing including a compressor inlet configured to receive a first medium, and a compressor outlet, wherein a compressed first medium is provided at the compressor outlet;

a conduit configured to receive a second medium; and

a heat exchanger integrally formed with the compressor housing, wherein the heat exchanger is fluidly connected to a portion of the compressor and to the conduit.
