摘要
窗户的安装方式在一定程度上影响围护结构热工性能,对窗户安装方式的研究对被动式低能耗建筑节能有重要意义。本文主要研究了被动式低能耗建筑中几种不同窗户安装方式和保温层厚度对围护结构整体性能的影响。通过有限元模拟软件THERM分别模拟窗户的下口、侧口(上口),得到窗口处的温度场和热流量,利用热桥计算方法得到安装热桥系数,对多种安装方式进行定量比较分析,得出各种安装方案的优劣,为被动式低能耗建筑中窗的外挂式安装提供参考。
The way of window installation affects the thermal performance of envelop structure to some extent.This paper mainly studies the influence of several different window installation methods and insulation thickness on the overall performance of the enclosure structure in the passive and low-energy buildings.By using the finite element simulation software THERM,the temperature field and heat flow at the lower and side openings of windows are simulated respectively. The thermal bridge coefficient is calculated by the thermal bridge calculation method,and the quantitative comparison of various installation methods is made.The advantages and disadvantages of various installation schemes are obtained to provide references for the installation methods of passive windows with the external hanging installation.
