Operation characteristic of a R123-based organic Rankine cycle depending on working fluid mass flow rates and heat source temperatures

摘要: Abstract The test and operation characteristic of an organic Rankine cycle using R123 a scroll expander have been investigated. steady-state is addressed with the varying working fluid mass flow rates ranging 0.124–0.222 kg/s heat source temperatures 383.15–413.15 K. behaviors detailed discussion for those four major components (pump, evaporator, condenser) are examined. experimental results show that environmental temperature presents higher influence on pump behaviors. range power consumption, isentropic efficiency back work ratio 0.21–0.32 kW, 26.76–53.96%, 14–32%, respectively. slight decrease first then sharp increase rate, while degree superheating more than 3 K necessary to avoid cavitation. generator efficiencies in 69.10–85.17% 60–73%, respectively, respective transfer coefficients evaporator condenser 200–400 450–2000 W/m2 K. maximum shaft electrical 2.78 kW 2.01 kW, system generating 3.25%. Moreover, tested thermal trend rate.
