- 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.
