摘　　要：为改善银川地区居住区夏季室外热环境,利用软件模拟得到某小区夏季气象典型日的室外温度云图,对温度过高的区域采用雾化设备进行物理降温的试验。结果表明,在不超过3.3 m/s的风力条件下,以3 m为半径的辐射范围内降温増湿效果最好,平均降温3℃左右,平均増湿6%~8%。可采用合理的布点方式,使用雾化设备对银川高层居住区的夏季室外热环境进行优化。In order to improve the outdoor thermal environment of residential areas in Yinchuan area in summer,the outdoor temperature cloud map of typical weather days in residential areas in summer is simulated by software.The experimental results show that under the wind condition of no more than 3.3 m/s,the cooling and humidity reduction effect is best within the radiation range of 3 m,with an average temperature drop of about 3℃and an average humidity increase of 6%-8%.The outdoor thermal environment of Yinchuan high-rise residential area in summer can be optimized by using atomization equipment to select the distribution area reasonably.
