【英文篇名】 Heat and mass transfer of moist air on a finned air cooler and fin efficiency 【作者中文名】 宋翀芳; 李安桂; 【作者英文名】 By Song Chongfang and Li Angui; 【作者单位】 太原理工大学; 西安建筑科技大学; 【文献出处】 暖通空调, Hv 湿工况; 表冷器; 肋片效率; 【英文关键词】 heat and mass transfer; wet cooling condition; surface air cooler; fin efficiency; 【摘要】 分析了肋片式表冷器在湿工况下的传热传质过程 ,认为表冷器对空气进行冷却减湿过程中不遵循路易斯关系式 ,推导出在湿工况下的冷却能力及肋片效率 ,计算表明当肋表面出现凝结时 ,会增加表冷器的冷却能力并影响肋片效率 【英文摘要】 Analyses the heat and mass transfer process on the surface of a finned air cooler in wet cooling conditions. Considers that the process that wet air is cooled and dehumidified on the surface of a finned air cooler does not abide by Lewis analogy. Deduces the cooling capability and fin efficiency in wet cooling conditions. Calculating results show that moisture condensation on the fin surface can enhance cooling capability and efficiency.
