| 摘 要： | 针对平肋肋片管式换热器的结霜过程，建立了数学模型，考虑了霜层密度变化和霜层阻力引起空气流量减小等因素。对结霜量随时间的变化和霜层密度的变化进行了数值分析和实验研究，模型计算结果和实验结果吻合得较好。

| Abstract: | Establishes a mathematic model, taking into account the variation of frost density and the decrease of airflow rate caused by frost layer. Studies the frost accumulation quantity and frost density of the plane-fin finned tube heat exchanger by numerical analysis and experiments. The calculated results are conformed to the experimental results better. |
