露点间接-直接蒸发冷却空调机组的实验研究
Experiments on dew-point indirect-direct evaporative cooling air conditioning unit
摘要：
搭建了实验台，对实验样机各功能段单独运行和组合运行时的性能分别进行了测试。结果表明，在实验范围内，预冷段和冷却段的最佳二次/一次风量比分别为1.2和1.69；整机联合运行时，出口终温低于入口空气的湿球温度，逼近露点温度。

Abstract：
Develops the test bed, and tests the performances on separated and connected operation modes of each functional section. The result shows that the optimal ratio of secondary air rate to primary one for pre-cooling section and cooling section is 1.2 and 1.69 respectively within experimental range. The outlet air temperature on combination operation mode is lower than the inlet wet-bulb temperature, approaching the dew-point temperature.
