| 中文摘要: |
| 冷却塔的冷却能力是衡量其性能的重要参数，多数测试标准对冷却能力的评价方法可分为冷却水量法与冷却水温法。本文通过一组实测数据对比分析了冷却水量法与冷却水温法这两种评价方法以及各标准间的差异性及存在问题，得出国内测试标准的冷却水温法评价结果比冷却水量法和美国CTI标准评价结果均偏差约2.3%的结论。并分析出主要原因是标准中设计水温差计算时风量取值为实测风量，为以后标准的修订提供了技术支持。 |

| The cooling ability is one of important parameters to measure the capacity of the cooling tower.Generally speaking, the current cooling ability evaluation method consists of the cooling water yield method and the cooling wa-ter temperature method.The study made a comparative analysis of the two kinds of cooling evaluation methods though a group of testing data as well as the distinctions and limitations between the different standards.The result made a conclusion that there exists a 2.3% deviation of the evaluation result between the domestic cooling water yield meth-od and the cooling water temperature method as well as the American CTI evaluation standard.In addition, the causa-tion of the results was also analyzed, which mainly owns to the air volume which is calculated as the measured air vol-ume during the design of water temperature difference calculation of the standard, which provides the technical sup-port for the further standard modification. |
