摘　　要：为研究极端天气对被动式太阳能建筑采暖效率的影响,选取关键气象参数(直射辐射、干球温度)来构造极端冷气象条件,主要分析太阳低辐射和极端低温对拉萨、乌鲁木齐、兰州、哈尔滨4个城市的被动式太阳能建筑采暖效率的影响。结果表明:随着太阳直射辐射和温度的降低,哈尔滨整个采暖季的采暖潜力下降最大,拉萨、兰州、乌鲁木齐在太阳直射辐射下降超过50%时,采暖潜力下降最大,哈尔滨在辐射下降43%时采暖潜力下降最大。在温度下降不超过10℃的情况下,拉萨和哈尔滨的采暖潜力下降最大,兰州和乌鲁木齐则是在温度分别下降11和15℃时,采暖潜力下降最大。气象参数对采暖潜力的敏感性分析表明,太阳直射辐射对太阳能采暖潜力的影响大于温度。同时,对不同设计因素进行全局敏感性分析,建筑保温材料的物理参数对采暖潜力的影响高于其他设计参数。To study the impact of extreme weather on the heating efficiency of passive solar buildings,key meteorological parameters(direct radiation and dry bulb temperature)were selected to construct extreme cold weather.The main focus was on analyzing the impact of low solar radiation and extreme low temperature on the heating efficiency of passive solar buildings in four cities:Lhasa,Urumqi,Lanzhou,and Harbin.The results show that with the decrease of direct solar radiation and temperature,the heating potential of Harbin decreases the most in the whole heating season.When direct solar radiation decreases by more than 50%,Lhasa,Lanzhou,and Urumqi experience the greatest decrease in heating potential,while Harbin experiences the most significant decrease when radiation decreases by 43%.Regarding temperature,Lhasa and Harbin exhibit the highest decrease in heating potential when the temperature decreases by no more than 10℃.On the other hand,Lanzhou and Urumqi experience the most significant decrease in heating potential when the temperature decreases by 11℃and 15℃,respectively.The sensitivity analysis of meteorological parameters on heating potential show that direct solar radiation has a greater effect on solar heating potential compared to temperature.Furthermore,the global sensitivity analysis of different design factors reveal that the physical parameters of building insulation materials have a higher impact on heating potential than other design parameters.
