摘要：
A systematic analysis of a Rankine cycle using R134a as the working fluid and a finite (314.5 kg/s) low temperature (100 degrees C) heat source shows that, for any fixed net power output, the evaporation pressure has upper and lower limits which depend on the pinch temperature of the heat exchangers and the quality of the working fluid at the turbine's exit. The maximum net power output and minimum heat exchanger conductance have been determined for these conditions.
