摘　　要：根据我国各地气候条件多变的特点,建立了各区域适用于蒸发冷却空调的六区模型,分析了直接蒸发与间接蒸发技术在各区域中的应用方式,搭建了可模拟各区域室外环境温湿度的蒸发冷却空调技术测试实验台进行实验测试,并与理论计算结果进行对比分析。结果显示,蒸发冷却在各区域中的适用形式基本与理论分析结果相符;实测各分区采用蒸发冷却技术的出风温度较理论值更低,冷却效果更好;当夏季空调室外计算湿球温度低于16℃时,采用直接蒸发进行加湿即可满足空调送风要求。According.to the characteristics of climate variability all over the country, establishes the six-district model with the evaporative cooling technology suited to different regions. Analyses the application modes of direct evaporation and indirect evaporation technology in different regions. Builds the test bed of the evaporative cooling air conditioning which can simulate the outdoor environment in different regions for the experimental measurements and compares with the theory studying. The resultsshow that the application form of the evaporative cooling technology in six-district is broadly consistent with the theory; that the measured value of the air temperature is lower than the theory value and the cooling effect is better; and that it can meet the requirements of air conditioning supply air with the direct evaporative cooling when the outdoor design wet-bulb temperature for summer air conditioning is below 16 ℃.
