A method and apparatus for generating power and for increasing the temperature of heat in a thermodynamic machine wherein a working fluid is circulated within a rotating rotor. In the machine, the rotor contains a heating heat exchanger and a cooling heat exchanger within the rotor, and also a working fluid heat exchanger to transfer heat from one stream of working fluid into another stream, so that one stream is heated and another cooled. The working fluid heat exchanger is in one or more steps, so that the working fluid stream into which heat is added, is being expanded during heat addition, and also the stream may be compressed with heat addition. Heat removal from the other working fluid stream may also be in steps. The machine may be a single rotor unit, or may have two rotors. Alternately, one of the rotors may be held stationary in some instances, to improve working fluid circulation within the machine cavity.
In a thermodynamic machine, wherein a working fluid is compressed and expanded in a cycle, with the compression being provided within an outwardly extending rotor passage and the expansion is being provided within an inwardly extending rotor passage, the outward and the inward ends of said passages being connected by fluid passages to form a continuous working fluid circulation loop, said circulation loop being provided with a heat removal heat exchanger, a heat addition heat exchanger and a regenerative heat exchanger to exchange heat between two streams of the working fluid, the improvement comprising:
In a thermodynamic method wherein a working fluid is compressed and expanded within a closed circulation loop in a centrifugal force field, and wherein a regenerative heat exchanger is provided to exchange heat between two streams of said working fluid, and wherein heat addition and heat removal are provided for the working fluid within said circulation loop, the improvement comprising:
