问题 问答题 简答题

在什么情况下对采暖室内外温差不需要进行修正?

答案

参考答案:

当供暖房间并不直接接触室外大气时,围护结构的基本耗热量会因内外传热温差的削弱而减少,为此引入了围护结构的温差修正系数,其大小取决于邻室非供暖房间或空间的保温性能和透气状况。若邻接房间或空间的保温性能差,易于室外空气流通,则该区域温度接近于室外气温,温差修正系数亦接近于1。若已知冷测温度或用热平衡法能计算出冷测温度时,可直接用冷测温度代入,不再进行温差修正。

Angela would work as hard as possible in physical treatment, and in exercise sessions.But she worked just as hard lying there faithfully doing her   37   , visualizing herself moving, moving, moving !

One day,   48   she was attempting, with all her might, to imagine her legs moving again, it seemed as though something   49   happened: the bed moved! It began to move around the room! She   50   out, "Look what I'm doing! Look'.Look! I can do it'.I moved! I moved!"
