摘要
研究小型会议室气流组织变化对热舒适性的影响,通过Airpak仿真软件对3种空调出风口角度设计方案下的温度、速度、压力及预测平均投票值(PMV)指标进行仿真分析。结果表明,水平出风方案的热环境效果最优,PMV小于0.5,满足人体热舒适性需求,温度分布较为均匀,风速设计合理。上调15°方案局部存在吹风感,温度分布不均;下调15°方案靠近风口位置人体感觉偏冷,整体空间分布不均匀。研究为会议室气流组织优化设计及空间布局合理性提供了参考。
The influence of air flow organization changes in small meeting rooms on thermal comfort is studied.The temperature,velocity,pressure and predicted average voting value(PMV)indicators under three design schemes of air conditioning outlet angles are simulated and analyzed through Airpak simulation software.The results show that the horizontal air outlet scheme has the best thermal environment effect,with a PMVless than 0.5,meeting the human body's thermal comfort requirements.The temperature distribution is relatively uniform and the wind speed design is reasonable.The 15°increase plan has a local blowing sensation and uneven temperature distribution.The 15°decrease plan makes people feel colder near the air outlet,and the overall spatial distribution is uneven.The research provides a reference for the optimal design of air flow organization and the rationality of spatial layout in the meeting room.
