Abstract

A compressing device includes a first turbine a second turbine and a compressor. The first turbine is configured to provide a first energy by expanding a first medium and the second turbine configured to provide a second energy by expanding a second medium. The compressor is configured to receive the first energy and the second energy during a first mode of the compressing device, receive the first energy during a second mode of the compressing device, and compress the second medium in accordance with the first mode or the second mode.

Claims (20)

1 . A compressing device, comprising:

a first medium provided from a first source and a second medium provided from a second source;

a turbine comprising a at least one inlet, wherein the first medium is receivable at the at least one inlet, and a mixture of the first medium and the second medium is receivable at the at least one inlet, the first medium and the second medium being mixed to form the mixture at a location upstream from the at least one inlet,

wherein the turbine is configured to provide a first energy by expanding the mixture and to provide a second energy by expanding the first medium;

a compressor configured to:

receive the first energy from the turbine during a first mode of the compressing device,

receive the second energy from the first medium during a second mode of the compressing device, and

compress the second medium in accordance with the first mode or the second mode.

2 . The compressing device of claim 1 , comprising:

a fan driven by the first energy during the first mode and the second energy during the second mode.

3 . The compressing device of claim 1 , comprising:

a power turbine configured to provide a third energy by expanding a third medium provided from a third source,

wherein the compressor is configured to receive the third energy from the third medium expanded across the power turbine.

4 . The compressing device of claim 1 , comprising:

a first component comprising the turbine and the compressor; and

a second component, which is separate from the first component, comprising a fan, a second turbine, and a shaft.

5 . The compressing device of claim 4 , wherein the fan is driven via the shaft by the first medium expanding across the second turbine.

6 . The compressing device of claim 1 , comprising:

a first component comprising the turbine and the compressor; and

a second component, which is separate from the first component, comprising a fan driven by a motor.
