A rankine cycle system (10) includes a heater (12) configured to circulate a working fluid in heat exchange relationship with a hot fluid to vaporize the working fluid. A hot system (14) is coupled to the heater (12). The hot system (14) includes a first heat exchanger (20) configured to circulate a first vaporized stream (34) of the working fluid from the heater (12) in heat exchange relationship with a first condensed stream (36) of the working fluid to heat the first condensed stream (36) of the working fluid. A cold system (16) is coupled to the heater (12) and the hot system (14). The cold system (16) includes a second heat exchanger (28) configured to circulate a second vaporized stream (38) of the working fluid from the first system in heat exchange relationship with a second condensed stream (40) of the working fluid to heat the second condensed stream (40) of the working fluid before being fed to the heater (12).
