Abstract
A dual-cycle heat engine employing a first cycling working fluid and a second cycling working fluid whose cycles overlap when fused into a combined working stream so as to preserve compression heat generated during compression of the first working fluid thereby yielding enhanced work extraction when complying with additional thermodynamic requirements.
Claims16
A method of exploiting heat during work generation in heat-engines, the method comprising:
- compressing vapor of a first liquid-vapor working fluid while contacting a second liquid working fluid so as to form a combined liquid working fluid containing compression heat and condensation heat released from compression and condensation of the vapor of the first liquid-vapor working fluid;
- isobarically vaporizing the combined liquid working fluid into a vaporized combined working fluid;
- expanding the vaporized combined working fluid into an expanded combined working fluid so as to extract work from the combined working fluid;
- splitting the expanded combined working fluid into the first liquid-vapor working fluid and a second liquid-vapor working fluid;
- and
- isobarically condensing vapor of the second liquid-vapor working fluid into the liquid working fluid.
