摘要
依据GB 50736—2012《民用建筑供暖通风与空气调节设计规范》中全国民用建筑供暖通风与空调室外气象参数,从夏季空调室外计算湿球温度大于等于23℃且小于28℃的161个中等湿度地区中选择29个典型城市,分析其全年及四季的平均干湿球温度差,计算间接蒸发冷却器在不同湿球效率下对室外空气湿球温度的降低程度,得出间接-直接蒸发冷却设备在分别配备湿球效率为60%,65%,70%,75%和80%的间接蒸发冷却器时的极限和实际出风(水)温度,为该设备在中等湿度地区的工程应用提供一定的参考。
According to the national outdoor meteorological parameters for heating,ventilation and air-conditioning of civil buildings in GB 50736-2012 Code for Design of Heating,Ventilation and Air Conditioning of Civil Buildings,29 typical cities are selected from 161 moderate humidity areas with outdoor calculated wet bulb temperature greater than or equal to23 C and less than 28 C in summer,and their annual and seasonal average dry wet bulb temperature differences are analyzed.The reduction degree of outdoor air wet bulb temperature by indirect evaporative cooler under different wet bulb efficiencies is calculated,and the limit and actual outlet air(water)temperature of indirectdirect evaporative cooling equipment when equipped with indirect evaporative cooler with wet bulb efficiency of 60%,65%,70%,75%and 80%respectively are obtained,which provides some reference for the engineering application of the equipment in moderate humidity areas.
