摘　　要：分析了拉萨、西安和西宁三地居住建筑在不同层数和保温要求组合条件下的采暖负荷;研究了拉萨多层居住建筑热负荷随窗墙面积比变化规律,以及单层传统民居在不同保温状况及有无附加阳光间时的热负荷.结果表明:各地的太阳辐射强度决定地区间的太阳能采暖保证率差别;太阳能采暖保证率随楼层减少、南向窗面积增大而升高.若对拉萨单层传统民居采取保温措施,并设置阳光间,可明显降低主动太阳能采暖集热器面积.Heating loads of residential buildings in Lhasa,Xi′an and Xining under combination conditions of different insulation,storey and window-wall ratio were analyzed.Single-layer traditional dwelling building in Lhasa City was also studied in different conditions.The results showed that： values of solar fraction in different cities depend on the local solar radiation,increasing with less layers and larger southern window.The collector area of active solar heating system can reduce significantly in single-layer traditional dwelling building with good insulation and sunspace in Lhasa city.
