中文摘要:
      自然通风作为一种生态建筑技术,相对于机械通风来说,既可以满足人们一定的舒适性要求,同时也可以降低能耗,创造可持续发展的绿色建筑环境。本文以垂直百叶遮阳百叶倾角为研究对象,采用PHOENICS软件对室内自然通风进行模拟分析。结果表明,随着百叶倾角θ从15°到165°的增大,室内各点风速呈波形变化,且波峰值与波谷值差值逐渐变小;当θ=90°时,即来流风风向与垂直百叶呈45°夹角时,室内涡流区域面积最小,气流组织均匀性最好。
英文摘要:
      Natural ventilation, as a kind of ecological building technology, compared with mechanical ventilation can meet the people's comfort requirements, at the same time, it can reduce energy consumption and create a sustainable development of green building environment..In this paper,taking the tilt angle of vertical blind angle as the object, the simulation of indoor natural ventilation by PHOENICS software is carried out.. The results showed that with the louver angle θ changes from 15 ° to 165 °,the wind speed indoor changes as a waveform, and the values of wave peaks and troughs arecloser, when θ = 90 °, that the angle of wind directionandvertical louvers angle is 45 °, thearea of indoor vortex is the smallest, that is the best uniformity of airflow indoor.
