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 。
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.
