中文摘要: 循环水流量是影响冷却塔热力性能的一个重要参数。以自然通风逆流湿式冷却塔为研究对象,基于焓差法理论,分析了循环水流量对冷却塔冷却效率及一些特性参数的影响。当循环水量增加时,出塔水温和出塔空气温度提高,塔的效率降低。
中文关键词: 冷却塔  循环水量  焓差法
Abstract:Circulating water flow is an important parameter that affects thermal performance for the cooling tower.Based on the natural draft wet cooling tower as the research object,the circulating water flow to the impact of the cooling efficiency of the cooling tower and some characteristic parameters are studied on the basis of the enthalpy difference method theory.When the circulating water increases,the water temperature and the air temperature of the outlet rise,while the efficiency of cooling tower decreases.
