摘　　要：为解决被动式太阳能建筑设计中辐射热与采暖需求之间的匹配问题,以非稳态传热原理为基础,提出评价被动式太阳房辐射热效用的"太阳能被动采暖热系数"指标.以拉萨和北京为例,通过计算该指标分析了两地被动式太阳能采暖的可用性.建立了主被动结合太阳能间歇式采暖系统的控制策略,据此分析了在太阳能丰富地区采用主被动相结合的间隙性采暖方式的可行性.To solve matching problem between the sun＇s available heat and heating demand in the design of passive solar building. The indicator of ＂solar passive heating thermal coefficient＂ （ SPHTC ） was proposed based on the principle of unsteady heat transfer. Based on case study of Lhasa and Beijing, the contribution of solar radiation for heating energy consumption was analyzed by calculating SPHTC. The control strategy for intermittent active and passive combined solar heating system was proposed, and the feasibility of such system in regions with rich solar energy was evaluated .
