以中低温地热资源的高效和经济利用为背景,在以涡旋膨胀机为膨胀部件的有机朗肯循环实验系统上,以R245fa为工质,在热源水进口温度、冷凝压力保持一定的条件下,实验考查有机朗肯循环系统性能随工质蒸发压力和膨胀机转速的变化规律。结果表明,工质蒸发压力和膨胀机转速取值均对系统性能有重要影响,分别存在最优蒸发压力和最优膨胀机转速。
Based on the high efficiency and economical utilization of medium and low temperature geothermal resources, on the organic Rankine cycle experimental system with scroll expander as the expansion component, using R245fa as working fluid, under the conditions of inlet temperature and condensing pressure of heat source water kept certain , Experimentally examines the organic Rankine cycle performance with the working medium evaporation pressure and expander speed changes. The results show that both the evaporation pressure of working fluid and the value of the expander speed have an important influence on the system performance, and the optimum evaporation pressure and the optimal expander speed exist respectively.
