建筑室内空间环境舒适性的数值模拟研究

摘要

本文利用CFD数值模拟技术对某卧室夏季工况中壁挂式空调运行情况下的空气风速度场、温度场以及空气龄场进行了直观的分析研究,结果表明壁挂式空调系统基本能承担室内热负荷,室内热舒适性良好.在风速方面,人员活动区(包括站姿与坐姿状态)气流速度适中,满足夏季室内风速舒适性的要求,大多数区域不会产生吹风感.但在空气质量方面,局部地区存在通风死角,有毒气体无法及时排出,不利于人们身体健康,必须采取有效措施加以改善.用CFD模拟室内环境与传统的实测法相比存在诸多优点,可以在未来的绿色设计中加以应用,以期为人们营造更舒适、健康的人居环境.%This paper analyzed the simulation speed air technology on air conditioning operation of hanging a bedroom in summer conditions under the field,temperature field and air age field directly using CFD numerical,and the results show that the wall hanging type air conditioner system can undertake indoor heat load,indoor thermal comfort is good.In terms of the wind speed,staff activities (including standing and sitting state) air speed is moderate,which has met the summer indoor wind comfort and most regions will not produce the sensation.But in terms of the air quality,no ventilation exists locally and toxic gases cannot be discharged in time,which is harmful for people's health.So we must take effective measures to improve these problems.There are many advantages compared with CFD simulation of indoor environment and the traditional measurement method,which can be used in future green building designs,in order to create a more comfortable,healthy living environment for the people.
