对以苯、氨、R11、R12、R134a和R113为工质的ORCs的效率进行了参数化分析和比较。在两条等压曲线之间运行时，系统效率在湿流体和干流体条件下分别增大和减小，在高涡轮进口温度条件下等熵流体达到近似恒定值。这些影响主要是由于流体的饱和蒸汽曲线的不同斜率和形状。等熵流体最适合回收低温余热。氟利昂及其替代品已被研究，并在ORCs中显示出类似的系统响应。1997爱思唯尔科学有限公司
The efficiencies of ORCs using cryogens such as benzene, ammonia, R11, R12, R134a and R113 as working fluids have been analyzed parametrically and compared. For operation between two isobaric curves, the system efficiency increases and decreases for wet and dry fluids, respectively, and the isentropic fluid achieves an approximately constant value for high turbine-inlet temperatures. These effects are primarily due to the different slopes and shapes of the saturation vapor curves of the fluids. Isentropic fluids are most suitable for recovering low-temperature waste heat. Freons and their alternatives have been studied and shown similar system responses in ORCs. (C) 1997 Elsevier Science Ltd.
