水冷式表冷器传热研究(2):以等价干工况为理论基础的试验方法 【英文篇名】 Heat transfer study of surface air coolers(2): A testing method based on equivalent dry cooling conditions 【作者中文名】 王晋生; 【作者英文名】 By Wang Jinsheng; 【作者单位】 解放军理工大学; 【文献出处】 暖通空调, Hv 试验方法; 等价干工况; 【英文关键词】 surface air cooler; testing method; equivalent dry cooling condition; 【摘要】 指出了目前表冷器试验方法中因含有析湿因数项而存在的缺陷 ,提出了以等价干工况为基础 ,只做湿工况变风量、干工况变风量和变水量试验的新方法。认为该方法遵循了焓差是湿工况下换热推动力的规律 ,试验工作量减少一半以上 ,对试验装置的要求降低 ,由试验数据整理出的公式用于表冷器热力计算完全可以满足空调常用范围内的要求 【英文摘要】 Points out the shortcoming of present water cooled air cooler testing procedure related to the dehumidification factor. Puts forward an improved method based on the theory in which the enthalpy difference is considered as the driving force in heat transfer under wet cooling conditions and thinks that the method can halve the testing work, require less for the experiment devices and reach higher accuracy.
