摘要:
针对以R245fa为工质的朗肯循环系统,运用Aspen换热器设计模拟软件,对该系统常用的满液式、降膜式和板式蒸发器进行结构设计和性能分析.在相同工况参数下,对比3种蒸发器的尺寸、造价和综合传热因子,结果表明:板式蒸发器最适用于有机朗肯循环系统.模拟改变波纹倾角β、板片厚度d及板间距↓时蒸发器内工质预热、蒸发、过热3个阶段传热过程,得出人字形板片结构对蒸发器传热系数、压降的影响规律.
Abstract:
For the Organic Rankine Cycle System ( ORCS)using R245fa as refrigerant, three types of evapo-rators are frequently-used, namely the flooded type,the falling film type and the plate type.Based on the ex-changer design and rating heat exchanger module in Aspen,this paper performed structure design and perform-ance analysis on these three types of evaporators. Under the same heat transfer medium and operating parame-ters,comparative analysis are made on size,cost and overall heat transfer factor of the evaporators.lt ’ s foundthat the plate type evaporator is most suitable for the ORCS;the effects of the corrugated inclination angle(β),plate thickness ( d) and plate spacing (l) on the evaporating, overheating and preheating of refrigerantsin the evaporator are analyzed through numerical simulation,thus the correlation between plate structure andthe heat transfer coefficient,pressure drop is concluded.
