幕墙整体传热系数的计算是通过一个面积加权的方法求得的。而幕墙中框及各种面材传热系数需要分别进行计算,在框与面材之间存在一个边界,这个边界不仅存在室内外纵向的传热,还存在框与面材之间的横向传热。如何准确的考虑这个边界的传热,是幕墙传热系数计算的关键问题。本文着重讲述一套框的传热系数计算方法,使其充分考虑边界传热在幕墙传热中的影响,仅供大家借鉴参考。

The whole curtain wall thermal transmittance is calculated by the method of area weighting,but the thermal transmittance of frames and different panels are needed to be calculated separately.There is a boundary between frame and panel,the boundary not only transfers heat lengthways,which lies inside and outside of a room,but also transfers heat breadthways.How to calculate the heat transfer in the boundary accurately.It is an important issue in curtain wall thermal transmittance calculate.This article mainly tells a calculate method of thermal transmittance about frame,it takes the impact of curtain wall boundary heat transfer into account adequately.Only to be referenced.
