旧工业建筑改造中的自然通风优化设计研究

A study on natural ventilation in renovation of industrial buildings

以计算机数值模拟为主要技术手段对杭州某工业厂房改造项目的自然通风进行了研究,对厂房室内自然通风的初始状况与不同的优化设计方案分别进行了数值模拟,并以风速为主要指标进行了比对分析,研究结果表明,优化后的设计方案与初始状况相比,风速有了较大提高,部分区域的风速从0.2 m/s提高到了0.5 m/s^1 m/s。

An industrial building located on Hangzhou suburb is used as a sample to study the natural ventilation simulation in this paper. The original ventilating design and optimized design using numerical simulation are compared on vent velocity. The results show that comparing the optimized design scheme with the preliminary state,the paper point out the wind speed is lorgely improved and the wind speed at some regions is increased from 0. 2 m/s to 0. 5 m/s - 1 m/s.
