摘　　要：对拉萨地区某4层被动太阳能住宅的采暖系统进行了设计探索,该系统以太阳能热水作为热源。其中被动太阳技术采用南向直接收益窗,窗墙面积比为0.56。主动太阳能热水系统以真空管集热阵列为主热源,电辅助加热为辅,地下保温蓄热水池进行短期热量蓄调,户内采暖系统采用地面辐射采暖。证明在拉萨地区,采用主、被动结合的太阳能采暖,利用屋顶集热器可保证拉萨地区4层及以下的居住建筑太阳能采暖保证率≥80%。A hot water solar heating system for a direct gain passive solar residential building of four-storey in Lhasa city was designed. The area ratio of window to wall is 0.56 in South for the designed building. Heating source system includes vacuum tube collector array, auxiliary electric heating boiler, hot water heating storage tank and indoor floor heating, system The results show that when active solar heating and the passive are combined, solar heating fraction will exceed 80% in four-storey residential building by using solar collectors set up on roof in Lhasa city.
