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 .In this paper,on the basis of steady state heat transfer analysis of the three heating elements,most in use in Inner Mongolia passive solar houses,thermal efficiency curves of heating elements under different meteorological conditions have been drawn.Through the analysis of these curves it has been found that the solarium is most efficient when levels of the total solar radiation and the ambient temperature appear to be very low,while the mass wall with vents is most efficient if the total radiation appears to be at higher levels.Of all the three elements,the mass wall without vents proves to be the least efficient.A design example is given for illustrating the practical use of these curves in passive solar heating design.
