摘要
房间围护结构热力系统传递矩阵元素Ｂ（Ｓ）的根数多少或根值大小，直接影响反应系数的精度。其值取多少，国内外没有统一标准。本文结合空调房间的下部送风，针对不同结构的房间进行探讨，发现最小根值取到（—３０）时，即足能满足一般精度要求。
Number or value of root of transmission matrix element B(S)for the envelope of a room has adirect influence on the accurary of the response factors.There is not a standard for the value of root in home and abroad. Considering the air conditioning rooms with different constructions,researches are carried out as regard to upward displacement system in the paper.It is found that the general accurary can befully met when the minimum root reaehes the value of(-30).
