| 摘 要： | 通过比较8种循环工质在有机朗肯循环(ORC)系统中的热力过程,从系统性能、可靠性、环保等角度综合考虑,验证了R245fa用于ORC循环工质的优势。以康明斯某重型车用发动机为应用目标,设计了一套余热回收发电系统,通过回收增压空气、尾管废气、发动机废气的热量,用于发电。经过计算,该系统的余热回收效率为10.4%。

| Abstract: | Eight kinds of cycle media in organic Rankine cycle(ORC) were compared during the thermodynamic process.Considering the systemic,reliable and environmental factors,R245fa was the optimum selection for ORC.For the application of Cummins heavy duty vehicle engine,the power generation system with the waste heat recovery was designed.Recovering the heat from charge air,tail pipe gas and exhaust gas,the power generation was realized.The efficiency of waste heat recovery in the system was 10.4%. |
