被动式太阳房冬季平均室温的予测及特朗勃墙的集热效率

PREDICATING THE MEAN ROOM AIR TEMPERATURE IN WINTER AND THE THERMAL EFFICIENCY OF TROMBE WALLS OF PASSIVE SOLAR HOUSES

本文提出了无孔及有通风孔的特朗勃集热墙的热效率曲线,并给出根据它们对集热墙式及直接受益窗与集热墙组合式的被动式太阳房的平均设计室温进行予测的手算方法。对于设计无辅助热源自然运行的被动式太阳房此法有重要实用价值。

The paper presents some formulas and curves to describe the heat collecting efficiencies of Trombe walls with or without vents. On the basis of the above, a method is also presented to predicate the mean room air temperature of compound passive solar houses with direct gain windows and heat collector walls. It is necessary and important for the design of a passive solar house without an auxilliary heat source.
