ABSTRACT:
A method and apparatus for generating heat and vaporizing of liquids, and for providing cooling by using a continuous flow centrifuge to compress a gas with accompanying temperature increase and removing heat to another fluid from said gas in compressed state; said gas then being passed from the first rotor via nozzles mounted on said first rotor in backward direction thus reducing the absolute tangential velocity of said gaseous fluid; said gaseous fluid being then passed to a second rotor for which the rotor tip speed may be nearly the same as the velocity of said entering gaseous fluid. After said gaseous fluid enters the second rotor, it is then passed inward within said second rotor and discharged near said second rotor center. Work is supplied to said first rotor normally, and recovered in said second rotor. The gaseous fluid may be air, carbon dioxide, or some other fluid. The fluid receiving said heat may be water, ammonia, or some other fluid. A third fluid may be employed to add heat to said gaseous fluid during expansion; then said gaseous fluid is directly returned to said first rotor; said third fluid may be water, or be some other fluid.
