湿式机械通风逆流冷却塔冷却能力检测
Cooling capacity testing of wet mechanical-draft counter-flow cooling tower
摘要：
依据机械通风冷却塔工艺设计规范和冷却塔的测试规程，对设计单位未给出其设计热力性能曲线的冷却塔，通过实际测试与Excel编程对设计规范和测试规程中提到的性能参数计算公式进行了验证，特别是对其冷却数Ω（特征数）的计算方法进行了深入研究，对测试规程中模糊的术语进行了阐述。

Abstract：
Based on the design standards and testing regulations for the mechanical draft cooling tower，for the cooling towers with their thermal performance curves not provided by designers, verifies the referred parameter formulas in design standards and testing procedures by practical testing and Excel programming. Especially makes a profound study on the calculation method of the cooling number Ω (a characteristic number) and clarifies some ambiguous terms in the testing regulation.
