This invention relates to power generation equipment and heat boosters, where a gaseous working fluid is compressed within a rotating rotor, heat is added or removed after such compression, and then the working fluid is expanded against centrifugal force within the rotor, and heat is again either added or removed from the working fluid. Where heat is added after the compression and heat removed after the expansion, the unit will be a power generator; where heat is removed after the compression and heat is added after the expansion, the unit will be a heat booster. Additionally, the unit may be provided with regeneration to exchange heat between the working fluid streams between such heat addition and heat removal. Working fluids that can be used are normally gaseous, and may be for example carbon monoxiode, or a halogenated hydrocarbon, or air.
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 provided within an inwardly extending rotor passage, the outward ends of said passages being connected by a first passage means and the inward ends of said passages being connected by a second passage means to form a continuous fluid circulation loop, (and wherein a hot heat exchanger is provided to exchange heat with the working fluid downstream of the compression within said outward extending rotor passages,), said fluid circulation loop being provided with a heat addition heat exchanger and a heat removal heat exchanger, the improvement comprising:
In a thermodynamic method of pumping heat and generating power, wherein a working fluid is compressed and expanded in a cycle, and heat is added into said working fluid and is rejected by said working fluid and wherein the work cycle is at least in part non-flow type, the improvement comprising:
