摘要
高层建筑中自然通风利用是一个工程难题。本文采用CFD软件分析幕墙通风器的不同布置方案,以验证室内换气效果满足《绿色建筑评价标准》(GB/T50378-2019)的要求。分析了方案1(4种不同开口)和方案2共计六种工况,比选出满足2次/h换气次数的方案。同时总结了幕墙通风器的优化路径,为类似项目提供参考。
The utilization of natural ventilation in high-rise building is a big engineering challenge.This paper aims to analyze the different layout schemes of ventilated curtain wall by CFD simulation and verify whether indoor air change rate meet the requirements of“Green Building Evaluation Standard”(GB/T50378-2019).To select the scheme which air change rate per hour is bigger than 2.There are 2 options being analyzed.Option 1 has four different type of openings and option2 has 2different type of openings.In the end,the optimization path of curtain wall ventilator was summarized,which could provide reference for similar projects.
