| 摘 要： | 阐述了环境风对空冷凝汽器散热的影响及防风网的防风原理,分析了防风网在空冷单元的防风效果,加装防风网可降低空冷风机入口风速,增大空冷风机吸入的空气量,进而提高空冷单元的换热效率。并就防风网的布置和结构形式对空冷岛防风效果的影响进行分析,防风网的开孔率和高度均对空冷单元的换热效率有一定影响。

| Abstract: | It summarizes the influence of ambient wind on air-cooled condenser and the working principle of windbreak net,analyzes the effect of the windbreak net in the air-cooled unit,and it is concluded that the installation of windbreak net can reduce the inlet wind velocity and increase the amount of air inhaled by the air-cooled fan,thus improving the heat transfer efficiency of the air-cooled unit.The passage also analyzes how the arrangement and structure of the windbreak net influence the windbreak effect of the air-cooled island,and the pierced rate and the height of windbreak net have certain influence on the heat transfer efficiency of the air-cooled unit. |
