基于airpak的室内臭氧扩散规律的模拟与研究

Simulation and Research of Indoor Ozone Diffusion Law Based on Airpak

近年来,由于室内空气净化器等电器的应用,导致其产生的臭氧在室内不断积累,同时室外大气中的臭氧也会通过围护结构的渗透作用进入室内。通过airpak软件对使用空气净化器的办公室进行数值模拟,分析室内外臭氧发生源对室内臭氧分布规律的影响。研究发现臭氧源的释放强度是影响室内臭氧浓度的主要因素,受气流组织、位置等因素的影响较小。基于不同的空气净化器臭氧散发速率、房间的体积及密封性,办公室内存在一定臭氧超标的风险。

In recent years,due to the application of indoor air purifiers and other electrical appliances,the ozone generated in the room continues to accumulate,and the ozone in the outdoor atmosphere will also enter the room through the penetration of the enclosure structure.In this paper,the airpak software is used to numerically simulate the office using an air purifier to analyze the effect of indoor and outdoor ozone sources on indoor ozone distribution.The study found that the release intensity of the ozone source is the main factor affecting the indoor ozone concentration,which is less affected by the air flow organization and location.Based on the ozone emission rate of different air purifiers,the volume and tightness of the room,there is a certain risk of ozone exceeding the standard in the office.
