根据Merkel的冷却塔传热传质理论,推导了适应于横流式冷却塔的传热模型,通过理论模型正交试验和实测数据因子相关性分析,研究了横流式冷却塔传热性能的影响因素。实测数据因子相关性分析结果表明,风量对横流式冷却塔传热性能影响程度最小,与理论模型正交实验结果存在一定的差异。运行时应保证横流式冷却塔进水流量的分布均匀,才能更有效的利用传热面积,提高横流式冷却塔传热效率。
According to the heat and mass transfer theory of Merkel’s cooling tower, the heat transfer model adapted to the cross-flow cooling tower is deduced. The influence factors of the heat transfer performance of the cross-flow cooling tower are studied by the theoretical model orthogonal test and the measured data factor correlation analysis . The correlation analysis of measured data shows that the air flow has the least influence on the heat transfer performance of the cross-flow cooling tower, which is different from the orthogonal experimental results of the theoretical model. Run-time should ensure that cross-flow cooling tower water inflow distribution, in order to more effectively use the heat transfer area, improve cross-flow cooling tower heat transfer efficiency.
