摘　　要：对中等湿度地区实际工程中的蒸发冷却空调系统,在不同季节开启不同功能段时的冷却效率进行了实验测试及分析。结果表明,无论在过渡季还是夏季,管式间接蒸发冷却器冷却效率的最大值超过80%;制取相同冷量,蒸发冷却空调机组的EER是机械制冷空调机组的3倍以上,只要运行合理,机组能耗可以降低50%左右。Tests and analyses the cooling efficiency of evaporative cooling air conditioning system with different functions in projects by experiments in the medium humid areas in different seasons.The result shows that the maximum of the cooling efficiency for tube type indirect evaporative coolers is over 80% in both transition seasons and summer.When making the same refrigeration output,the energy efficiency ratio（EER） for evaporative cooling air conditioning units is more than three times as higher as that for mechanical refrigeration units.So long as operating reasonably,the energy consumption of the units can be decreased by about 50%.
