Claims
- 1. A method of compressing a compressible fluid comprising:
- a. alternately compressing and expanding said fluid in a first compressing and expanding means; subsequently
- b. compressing said fluid in a second compressing means with accompanying temperature increase;
- c. removing heat from said fluid downstream of the second compressing means and adding said heat into said fluid during the alternate compressing and expanding steps, within either said first compressing or expanding means.
- 2. The method of claim 1 wherein the heat addition into said fluid during the alternate first compression or (and) expansion is within said expanding means.
- 3. The method of claim 1 wherein the heat removal from said fluid downstream of the second compressing means is at approximately constant pressure.
- 4. The method of claim 3 wherein said heat removal at approximately constant pressure is performed within a centrifuge type machine.
- 5. The method of claim 1 wherein a separate heat transfer fluid is provided for removing the heat from the fluid downstream of the second compressing means and adding said heat into the fluid during the first alternate compressing or expanding means.
- 6. The method of claim 1 wherein the heat addition into said fluid during the alternate compression and expansion is within said first compressing means.
- 7. The method of claim 1 wherein said fluid is further expanded in another expansion means downstream of the heat removal and second compressing steps.
- 8. The method of claim 1 wherein in the first alternate compressio or expansion steps the work input during the compression and the work output during the expansion by the said fluid are approximately equal.
