The proposed method has the capability of predicting the performance of condenser including threedimensional effects due to the change of cooling water temperature and the multiple tube paths arrangement. The proposed algorithm is more suitable to the condenser of multiple tube-paths than existing method. The proposed method is applied to a N11220-1 condenser to demonstrate its predictive capability, the results indicate that condensation rate of each bay and the air concentration at gas offtake is quite different, which can not be predicted by two-dimensional method.
