Abstract
An improved closed loop thermodynamic system that recirculates the vaporizable working fluid between its liquid and vapor states include a thermal regeneration unit that receives vaporized working fluid after its utilization and transfers a portion of the enthalpy contained therein to condensate, the pressure of which has been raised to the highest vapor pressure in the closed loop system by communication with a vaporizing unit therein. The vaporized working fluid, from which the regenerative heat has thus been extracted, is then directed to a condensing unit of known type for condensation therein and any incidental condensation formed during the course of the regenerative heat transfer from the vaporized working fluid is collected in a separate portion of the regeneration unit and is periodically transferred to join the condensate flowing from the condensing unit to the regeneration unit for regenerative heating therein. This improved closed loop recirculating thermodynamic system effects all fluid transfers by natural convection, force of gravity, and judicious application of the highest and lowest pressures available within the system by selective communication between portions of the system.
