Thermal Stability and Material Compatibility of HFC245fa as Organic Rankine Cycle Working Fluids

Keywords： Organic Rankine Cycle (ORC) , HFC245fa , thermal stability , material compatibility

对于中高温热源,有机朗肯循环是一种高效灵活的能量回收利用方式.但在中高温热源的温度范围内,有机物可能会发生热分解,因此有机工质的热稳定性成为制约工质筛选的首要因素.HFC245fa因为其良好的热力性能和环保性,被认为是有良好应用前景的有机朗肯循环工质.本文主要对HFC245fa的热稳定性和材料相容性进行实验研究.结果表明,HFC245fa的热分解温度在300～320℃之间,且铜和铝对HFC245fa的热分解都有明显的催化作用,同时HFC245fa也会改变部分材料的物理性质,同时在材料表面产生积碳.
