氨高效节能冷风机研究

本文是一篇氨高效节能冷风机研究的综合报告。文章介绍了作者研制的适合于氨冷风机蒸发器用的双面V形长槽肋片管的小件试验,优化试验,现场样机的对比测试。试验结果表明,双面V形长槽优化肋片管应用于氨冷风机与常规使用的矩形平板式肋片管相比,空气侧当量换热系数平均提高18.25％,总传热系数提高12.85％。最后还介绍了采用这种双面V形强化传热肋片管的氨高效节能冷风机的整机结构设计。按设计制造的冷风机,经多个单位使用,证明该冷风机具有结构紧凑,占地面积小,传热效率高,维护管理方便等特点,有显著的经济效益。

RESEARCH OF HIGH EFFICIENT ENERGY-SAVING AMMONIA AIR COOLER

This paper is a comprehensive report about the research of high efficient energy-saving ammonia air cooler. In the paper, it is introduced that the test of two-side long V-groove finned pipes which are fit for the evaporators of ammonia air coolers, optimum experiments of the finned pipes, and field experiments of contrasting the model machine with the old one in a cold storage. The result shows that the air-side heat transfer performance coefficient and the overall heat transfer performance coefficient of the two-side optimum long V-groove finned pipes are higher from 18.25% and 12.85% than those of conven tional rectangular plain-plate finned pipes respectively. At last, it is introduced the structure design of the high efficient energy-saving air cooler. Used by a few of units, it is proved that this type of air cooler has characteristics of compact structure, less floor area occupied, high heat transfer efficiency, convenient maintenance and management, and is of notable economical effect.
