超低能耗建筑中的幕墙连接结构传热分析及优化探索

Heat Transfer Analysis and Optimization Exploration of Curtain Wall Connection Structure in Ultra-low Energy Building

超低能耗建筑的外装饰采用幕墙形式时,幕墙与墙体的连接结构有产生热桥的风险,本项目针对幕墙干挂系统的一种典型连接结构为研究对象,通过数值模拟对其传热进行分析并提出合理的断热措施,为后期超低能耗建造提供参考。

When the exterior decoration of ultra-low energy building adopts curtain wall system,the connection structure between curtain wall and wall has the risk of thermal bridges.This project focuses on a typical connection structure of the curtain wall dry hanging system.The heat transfer is analyzed through numerical simulation and puts forward reasonable heat cut-off measures,which could provide a reference for the later ultra-low energy buildings.
