Abstract
A closed loop thermodynamic system that recirculates a vaporizable working fluid between its liquid and vapor states includes a thermal regeneration unit that receives exhausted working fluid after its utilization in an energy-utilizing device and transfers a portion of the enthalpy contained therein to a pressurized flow of condensed working fluid to a vaporizing unit in the system. Uncondensed exhausted vapor, after regenerative heat has thus been extracted, is then directed to a condensing unit of known type for condensation therein and collection in a condensate-holding unit. Condensation formed from the exhausted vapor during the course of the regenerative heat transfer therefrom is collected in a pool in the regeneration unit and is transferred to join the condensate in the condensate-holding unit to be flowed through the regeneration unit for regenerative heating therein. A pump is provided between the condensate-holding unit and the vaporizing unit to ensure that the regenerative heating is provided to liquid working fluid at the highest pressure in the system regardless of the different heights at which the various units are located.
