基于气象数据的乌鲁木齐建筑太阳辐射特性研究
|
摘要
根据乌鲁木齐气象站点1996-2015年气象观测数据,理论分析并结合乌鲁木齐地区特殊的地理位置,经过统计计算得出该地区采暖期(10月-次年3月)建筑外墙的太阳总辐射照度逐时变化特征,并与建筑气象参数标准中同一地区逐时的太阳总辐射照度进行了对比。结果表明:南外墙所接收的太阳逐时辐射照度最大。且近年乌鲁木齐建筑南外墙的小时太阳辐射照度总量呈减少趋势,南外墙2月份的小时辐射照度总量衰减到2604 W/m2。
The hourly total solar radiation variation characteristics of the building exterior wall during the heating season(October ～ March) is calculated from meteorological observation data(1996～2015) of Weather Information Center of Xinjiang Uygur Autonomous Region. Moreover, the hourly solar irradiance of building meteorological parameter standards in the same area was compared and the main factors which affecting solar radiation are also analyzed. The results show that the hourly solar irradiance of the South outer wall is the largest. In recent years, the total solar radiation intensity of the South outer wall of Urumqi building is decreasing, and the total radiation intensity of the South outer wall in February is attenuated to 2604 W/m2.
