摘　　要：针对GB 50736—2012《民用建筑供暖通风与空气调节设计规范》中夏季空调室外设计湿球温度不低于28℃的31个高湿度地区,对采用间接-直接蒸发冷却空调设备制取的冷水(风)温度进行研究。计算不同湿球效率(60%,65%,70%,75%和80%)间接蒸发冷却器对室外空气湿球温度的降低程度,并分析采用间接-直接蒸发冷却技术可制取的冷水(风)极限温度和实际冷水(风)温度。According to GB 50736-2012 Design code for heating, ventilation and air conditioning of civil buildings, the chilled water(air) temperature produced by indirect-direct evaporative cooling air-conditioning equipment is analyzed for 31 high humidity areas with not lower than 28 ℃ outdoor design wet bulb temperature of air-conditioning in summer. The reduction degree of outdoor air wet bulb temperature by indirect evaporative coolers with different wet bulb efficiencies(60%, 65%, 70%, 75% and 80%) is calculated, and the limit temperature of chilled water(air) and the actual chilled water(air) temperature produced by indirect-direct evaporative cooling technolo-gy are analyzed.
