摘　　要：基于传热单元数法,建立了冷凝器的数学模型,模拟了两种不同流路冷凝器的换热性能和阻力特性。对比结果表明,冷凝器沿管长的壁温分布与前人的实验结果较为一致,阻力计算结果与实验结果最大偏差为7%,该模型可以用来比较不同形式流路对冷凝器性能的影响。Based on the ε-NTU method, develops a mathematic model of condenser and simulates the heat transfer performances and the resistance characteristics of two condensers with different refrigerant flow arrangements. The results show that the location tube-wall temperature distribution along the tube length agrees with experimental results recorded in previous literature, that the maximum total pressure error between the numerical simulation and the experimental values is 7%, and that the mathematic model can be used to compare the effect of flow arrangements on the perlormance oi condensers.
