摘　　要：以国产大型机组冷却塔为研究对象,通过试验与理论分析影响冷却塔经济运行的各种因素,详细介绍在试验条件下各种淋水填料对冷却塔出水温度及机组经济性的影响。研究认为,冷却塔冷却面积的大小直接决定冷却塔的冷却能力,淋水填料是冷却塔的关键部位,在冷却面积确定的情况下其性能对冷却塔的冷却能力起决定性作用。冷却塔利用新型淋水填料进行改造,可获得巨大的经济效益。Taking air-cooling tower as study object, analysis is made on all factors concerning economic operation of air-cooling tower by test and theory. It elaborates on outlet water temperature and economic impacts on air-cooling tower by water drenching filler under test condition. The study shows the size of the cooling areas is decisive for cooling capacity of the cooling tower; water drenching filler is a key component of cooling tower. If cooling area is certain, the function of which is decisive in cooling. It will bring great economic benefit once cooling tower is retrofitted with water drenching filler.
