摘要
选取R123,R141b,R245ca,R245fa,R601,R601a作为有机朗肯循环的工质,在不同蒸发温度条件下,对其热力循环特性进行了计算分析,以热力学第一定律和第二定律为基础进行了比较。结果表明,R141b是适合本循环系统的最佳工质。同时还研究了汽轮机进口温度和进口压力对该系统的净功量、吸热量及热效率的影响。
Under the proposed working conditions, R123, R141 b, R245 ca, R245 fa, R601, R601 a are chosen as the working fluids of the low-temperature Rankine cycle system, then thos working fluids are investigated and compared based on first law of thermodynamics and second law of thermodynamics. Results show that R141b is an available and effective working fluid for low-temperature Rankine cycle. The impact of the turbine output temperature and pressure on the system performance of organic Rankine system was investigated. Including system net output power, heat absorption capacity and thermal efficiency.
