1. A rankine cycle system, comprising:

  • a heater configured to circulate a working fluid in heat exchange relationship with a hot fluid to vaporize the working fluid;

    a hot system coupled to the heater;

    wherein the hot system comprises a first heat exchanger configured to circulate a first vaporized stream of the working fluid from the heater in heat exchange relationship with a first condensed stream of the working fluid, thereby heating the first condensed stream to produce therefrom a second vaporized stream of the working fluid; and

    a cold system coupled to the heater and the hot system;

    wherein the cold system comprises a second heat exchanger configured to circulate the second vaporized stream of the working fluid from the hot system in heat exchange relationship with a second condensed stream of the working fluid to heat the second condensed stream of the working fluid before being fed to the heater.
