摘　　要：本文在对内蒙古被动式太阳房中三种常用集热部件进行稳态传热分析的基础上 ,绘制了不同气象条件下的集热部件效率曲线。通过分析这些效率曲线可知 :在总辐射强度和室外气温都很低时 ,附加阳光间式太阳房的效率最高 ;当总辐射强度较高时 ,有通风孔的实体墙式太阳房效率最高 ;效率最低的是无通风孔的实体墙式太阳房。本文最后通过一算例进一步阐述了效率曲线在被动式太阳房热工设计中的具体应用。In this paper,on the basis of steady state heat transfer analysis of the three common heating elements in Inner Mongolia passive solar houses,the thermal efficiency curves of heating elements in different meteorological conditions have been developed.By analyzing these curves,it can be seen that the solarium is the most effective at very low levels of total solar radiation and low ambient temperatures the mass wall with vents is most efficient at higher leves of total radiations and the mass wall is the least efficient of all the three elements studied.The practical use for these curves in passive solar heating design is illustrated by a worked design example.
