Parameter analysis of waste heat recovery system of latent heat utilization compound organic Rankine cycle-partB
在partA研究基础上进一步探究工作参数变化对系统性能的影响,研究得出较高的高温循环蒸发压力和较低的高温循环冷凝压力可以提高系统余热回收效率;低温工质与冷却液的换热器、低温循环冷凝器、集成式蒸发/冷凝器和低温循环膨胀机的㶲损占比较高,可以作为优化的目标过程。在重型柴油机某工况下以系统净输出功率、系统㶲效率和㶲损为目标对象,按照对低温循环蒸发压力进行分段的加热策略,探究循环中关键工作参数的影响。结果表明,系统的输出功率、㶲效率和㶲损最佳可以达到 2…查看全部>>
Based on the partA study,we further investigate the effect of the change of operating parameters on the system performance,and conclude that higher high-temperature cycle evaporation pressure and lower high-temperature cycle condensing pressure can improve the system waste heat recovery efficiency;the heat exchanger of low-temperature working mass and coolant,low-temperature cycle condenser,integrated evaporator/condenser,and low-temperature cycle expander h…查看全部>>
