工业循环水冷却塔改造效果的测试与评价

On Improvement of Cooling Tower in the Industrial Circulating Water System

探讨了工业循环水冷却塔改造后其热力性能的测试及有关数据的推算方法、步骤和改造效果的评价方式等方面的问题 ,提出冷却塔的改造效果应以改造后与改造前冷却能力 ηst的差值Δηst作为衡量的标准。在利用实测数据进行推算时可以采取近似计算方式 ,并在使用填料的热力特性方程之前要对其进行修正。

The regular renovation of industrial cooling tower has to be carried out to keep the cooling performance. Research was conducted on the appreciation method of the improved effect, the method and procedure of the heating power's test and the calculation of the data etc. after the renovation. The D value, a differential value of cooling capacities after and before the renovation, was put forward as the judgment standard to the cooling tower improvement. It is necessary to adopt the approximation method for calculation, but the amendment of them must be made before using the Equation of the Thermodynamic.
